DETAILED DESCRIPTION

Technical solutions in some embodiments of the present disclosure will be described clearly and completely in combination with accompanying drawings. Obviously, the described embodiments are merely some but not all embodiments of the present disclosure. All other embodiments obtained on a basis of the embodiments of the present disclosure by a person of ordinary skill in the art shall be included in the protection scope of the present disclosure.

Unless the context requires otherwise, throughout the description and the claims, the term “comprise” and other forms thereof such as the third-person singular form “comprises” and the present participle form “comprising” are construed as open and inclusive, i.e., “including, but not limited to”. In the description, the terms such as “one embodiment”, “some embodiments”, “exemplary embodiments”, “example”, “specific example” or “some examples” are intended to indicate that specific features, structures, materials or characteristics related to the embodiment(s) or example(s) are included in at least one embodiment or example of the present disclosure. Schematic representations of the above terms do not necessarily refer to same embodiment(s) or example(s). In addition, the specific features, structures, materials or characteristics may be included in any one or more embodiments or examples in any suitable manner.

The phrase “at least one of A, B, and C” has a same meaning as the phrase “at least one of A, B, or C”, and both include the following combinations of A, B, and C; only A, only B, only C, a combination of A and B, a combination of A and C, a combination of B and C, and a combination of A, B, and C.

A liquid crystal display device includes a backlight module and a display panel that are stacked. The backlight module is disposed on a back side of the display panel (i.e., a side opposite to a display surface side of the display panel), and the backlight module is configured to provide light to the display panel, so that the display panel may display an image.

As shown inFIGS.1and1B, according to different arrangements of a light source, the backlight module mainly includes a side-type backlight module and a direct-type backlight module.

As shown inFIG.1A, for example, the side-type backlight module100includes a backplane10, a light source20and a light guide plate30. The light source20is disposed at an end of the light guide plate30, and the backplane10is disposed on a side of the light guide plate30configured to face away from the display panel.

A process of providing light by the side-type backlight module100is roughly as follows. The light source20emits light, and the light enters an interior of the light guide plate30from an end of the light guide plate30and exits from a side of the light guide plate30facing away from the backplane10after being guided by the light guide plate30, thereby providing required backlight for the display panel.

In some cases, the side-type backlight module100further includes a reflective plate40capable of re-reflecting light emitted from a side of the light guide plate30facing the backplane10back to the interior of the light guide plate30, thereby improving a utilization rate of the light.

In the side-type backlight module100, the backplane10is configured to support and protect the light guide plate30. In a case where no reflective plate40is disposed between the backplane10and the light guide plate30, the backplane10may further have a reflective function, i.e., re-reflect the light emitted from the side of the light guide plate30facing the backplane10back to the interior of the light guide plate30.

As shown inFIG.1B, the direct-type backlight module100′ includes a backplane10, a light source20′ and a diffusion plate30′. The light source20′ is disposed on a side of the backplane10facing the diffusion plate30′, and the backplane10is disposed at a side of the light guide plate30′ configured to face away from the display panel.

A process of providing light by the direct-type backlight module100′ is roughly as follows. The light source20′ emits light, and the light enters the diffusion plate30′ and exits from a side of the diffusion plate30′ facing away from the backplane10′ after being uniformly dispersed by the diffusion plate30′, thereby providing required backlight for the display panel.

In the direct-type backlight module100′, the backplane10is configured to support and protect the light source20′, and the backplane10further has a reflective function, i.e., reflect light emitted by the light source20′ and directed to the backplane10to the diffusion plate30′.

In some embodiments, the backplane included in the backlight module is a metal backplane, which has disadvantages of easy deformation, easy expansion when heated, complex structure, high mold opening cost and the like. Compared with the metal backplane, a glass backplane has advantages of being good in flatness, light and thin, anti-glare, good in weather resistance, free of mold opening and the like, and thus becomes one of choices of the backplane in the backlight module. However, since glass itself has disadvantages of fragility, poor impact resistance, light transmission and the like, a wide application of the glass backplane in the liquid crystal display device is limited.

On this basis, as shown inFIGS.2A to5, some embodiments of the present disclosure provide a glass backplane. For ease of description of relative positions of a plurality of film layers included in the glass backplane200, reference is made toFIG.2A, where two opposite sides of each film layer are a first side A and a second side B. InFIGS.2B to5, the two opposite sides of each film layer included in the glass backplane200are the same as those inFIG.2A.

The glass backplane200includes a tempered glass substrate1, a light-shielding layer2and a reflective layer3.

The tempered glass substrate1is obtained by tempering a glass base. Compared with a common glass substrate, the tempered glass substrate has a stronger impact resistance and thermal stability, stronger carrying capacity, and is not easy to break with higher safety.

In some embodiments, the glass base used to manufacture the tempered glass substrate1is obtained by cutting float glass, such as low-iron float glass. The float glass has advantages of good transparency, free of glass furuncles and bubbles, good optical performance, good flatness, compact structure, being not easy to break and the like. The float glass is selected and made to be a glass base and tempered to obtain the tempered glass substrate1, which may improve flatness of the backplane200and further improve impact resistance of the glass backplane200.

Referring toFIGS.2A to5, two opposite sides of the tempered glass substrate1are a first side A and a second side B. In a case where the glass backplane200is applied to a backlight module, the first side A of the tempered glass substrate1is closer to a light source in the backlight module than the second side B.

The light-shielding layer2is disposed on a surface of the first side A of the tempered glass substrate1, two opposite sides of the light-shielding layer2are a first side A and a second side B, and the second side B of the light-shielding layer2is closer to the tempered glass substrate1than the first side A of the light-shielding layer2. The light-shielding layer2is configured to reduce light transmittance of the tempered glass substrate1and prevent light from passing through the tempered glass substrate1.

The reflective layer3is disposed at the first side A of the light-shielding layer, and is configured to reflect light to improve light reflection performance of the glass backplane200.

The glass backplane200provided in the embodiments of the present disclosure includes the tempered glass substrate1, the light-shielding layer2and the reflective layer3that are stacked successively. The tempered glass substrate1itself has strong impact resistance and high carrying capacity. The light-shielding layer2is disposed on a side of the tempered glass substrate1, and is capable of reducing the light transmittance of the tempered glass substrate1. The reflective layer3is disposed at a side of light-shielding layer2facing away from the tempered glass substrate1, and is capable of reflecting light. In this way, when light is directed to the glass backplane200, the light is reflected under action of the reflective layer3and exits in a direction away from the glass backplane200. Moreover, the light cannot pass through the light-shielding layer2to reach the tempered glass substrate1under action of the light-shielding layer2. Therefore, problems of poor impact resistance and light transmission of the glass are solved, and the glass backplane200is with an improved impact resistance, is not easy to break, has excellent deformation resistance and is less affected by environment (e.g., temperature changes and humidity changes). That is to say, the glass backplane200provided in the embodiments of the present disclosure further has strong deformation resistance, low light transmittance and certain light reflection performance with advantages of being good in the flatness, good in the weather resistance, not easy to expand and deform, light and thin, free of the mold opening and the like.

A position of the light-shielding layer2and a position of the reflective layer3in the glass backplane200provided by the present disclosure are not limited to the ones in the above arrangements. In some other embodiments, the light-shielding layer2and the reflective layer3may further be disposed at other positions. For example, the light-shielding layer2is disposed on the second side B of the tempered glass substrate1, and the reflective layer3is disposed at the first side A of the tempered glass substrate1. For example, the light-shielding layer2is disposed on the second side B of the tempered glass substrate1, with the first side A of the light-shielding layer2being closer to the tempered glass substrate1than the second side B of the light-shielding layer2, and the reflective layer3is disposed at the second side B of the light-shielding layer2.

In some embodiments, a material of the light-shielding layer2is not limited, as long as the material is capable of shielding light. For example, the material of the light-shielding layer2is ink, a black color resistor, a black light-absorbing film, or the like.

In some examples, the material of the light-shielding layer2is high-temperature ink. For example, the high-temperature ink is capable of withstanding a temperature in a range of 500° C. to 850° C. Compared with low-temperature ink, the high-temperature ink has characteristics such as a higher adhesive force and stronger weather resistance, and has a higher hiding power. By selecting the high-temperature ink as the material of light-shielding layer2, the light-shielding layer2may be firmly adhered to a surface of the tempered glass substrate1, and corrosion resistance of the light-shielding layer2may be improved.

In some examples, in a case where the light-shielding layer2is disposed on the surface of the first side A of the tempered glass substrate1, and the material of the light-shielding layer2is the high-temperature ink, a method of manufacturing the glass backplane200provided by the present disclosure is as follows. After the light-shielding layer2is formed on a surface of a first side A of the glass base, the glass base with the light-shielding layer2formed thereon is tempered, so as to transform the glass base into a tempered glass substrate1. In a process of tempering the glass base with the light-shielding layer2formed thereon, a simultaneous heating and then a drastical temperature reducing are required to be made to the glass base and the light-shielding layer2, and with the high-temperature ink being selected as the material of the light-shielding layer2due to its characteristics such as high adhesive force and strong weather resistance, it is possible to avoid phenomena of falling off and fading of the light-shielding layer2caused by an insufficient adhesive force and unstable performance of the material of the light-shielding layer2in the heating process. After the glass base with the light-shielding layer2being formed thereon is tempered, the high-temperature ink may be in closer contact with the surface of the tempered glass substrate1. Therefore, the light-shielding layer2is closely attached to the surface of the tempered glass substrate1and is not easy to fall off.

In some embodiments, by setting a thickness of the light-shielding layer2within an appropriate range, it is possible to avoid that the glass backplane200is not light and thin enough due to a fact that an overall thickness of the glass backplane200is increased due to an excessively large thickness of the light-shielding layer2, and it is further possible to avoid that a light transmission phenomenon of the glass backplane200cannot be effectively improved due to a fact that light-shielding performance of the light-shielding layer2for the tempered glass substrate1is insufficient due to an excessively small thickness of the light-shielding layer2.

For example, the thickness of the light-shielding layer is greater than or equal to 29.5 μm, and is less than or equal to 30.5 μm. In this way, not only is it possible to ensure that the light-shielding layer2is capable of effectively improving the light transmission phenomenon of the glass backplane200, but also it is possible to ensure that the glass backplane200is light and thin. For example, the thickness of the light-shielding layer2is 29.5 μm, or the thickness of the light-shielding layer2is 30 μm, or the thickness of the light-shielding layer2is 30.5 μm.

In some embodiments, the thickness of the light-shielding layer2is related to the material thereof. For example, in the case where the material of the light-shielding layer2is the high-temperature ink, the thickness of the light-shielding layer2is greater than or equal to 29.5 μm, and is less than or equal to 30.5 μm. In this way, not only is it possible to ensure that the light-shielding layer2is capable of effectively improving the light transmission phenomenon of the glass backplane200, but also it is possible to ensure that the glass backplane200is light and thin. For example, the thickness of the light-shielding layer2is 29.5 μm, or the thickness of the light-shielding layer2is 30 μm, or the thickness of the light-shielding layer2is 30.5 μm.

In some embodiments, as shown inFIGS.2A to5, the reflective layer3includes a first sub-layer31disposed at the first side A of the light-shielding layer2. The first sub-layer31includes a base and reflective particles, and the reflective particles are dispersed in the base, and are configured to reflect light.

In the above embodiments, the reflective layer3includes the first sub-layer31. The reflective particles included in the first sub-layer31are configured to reflect the light, and the base serves as a matrix for carrying the reflective particles, so that the reflective particles may be dispersed in the base and form a film layer, which is disposed in the glass backplane200, together with the base. In this way, when the light is incident on the glass backplane200, the light is reflected under reflection action of the first sub-layer31, and exits in the direction away from the glass backplane200, thereby effectively preventing the light from passing through the tempered glass substrate1and improving the utilization rate of the light.

In some embodiments, a material of the base in the first sub-layer31is not limited, as long as the material is capable of carrying the reflective particles. For example, the material of the base includes at least one of acrylic resin, polymethyl methacrylate and polyethylene glycol terephthalate (PET). Acrylic resin, polymethyl methacrylate and PET all have characteristics of transparency, good wear resistance, good weather resistance, no toxicity and the like. By using these materials as the material of the base, the reflective particles may be dispersed therein, the reflective particles may be carried, and light reflection performance of the reflective particles is not affected.

In some embodiments, a material of the reflective particles in the first sub-layer31is not limited, as long as the material is capable of reflecting light. For example, the material of the reflective particles includes at least one of titanium dioxide, zinc oxide and zirconium oxide. Titanium dioxide, zinc oxide and zirconium oxide all have strong light reflection performance. Therefore, by dispersing the reflective particles in the base, the light directed to the glass backplane200may be effectively reflected.

A specific composition of the first sub-layer31may be any combination of the material included in the base and the material included in the reflective particles. For example, the composition of the first sub-layer31is that acrylic resin is used as the base, and titanium dioxide particles are dispersed in the acrylic resin. Or, the composition of the first sub-layer31is that acrylic resin is used as the base, and titanium dioxide particles and zinc oxide particles are dispersed in the acrylic resin. Or, a mixture of acrylic resin and polymethyl methacrylate is used as the substrate, and titanium dioxide particles, zinc oxide particles and zirconium oxide particles are uniformly dispersed in the mixture.

In some embodiments, by setting a thickness of the first sub-layer31within an appropriate range, it is possible to avoid that the glass backplane200is not light and thin enough due to a fact that the overall thickness of the glass backplane200is increased due to an excessively large thickness of the first sub-layer31, and it is further possible to avoid that the first sub-layer31is incapable of reflecting light effectively due to an excessively small thickness of the first sub-layer31.

For example, the thickness of the first sub-layer31is greater than or equal to 50 μm, and is less than or equal to 100 μm. In this way, not only is it possible to ensure that the first sub-layer31is capable of effectively reflecting light, but also it is possible to ensure that the glass backplane200is light and thin. For example, the thickness of the first sub-layer31is 60 μm, or the thickness of the first sub-layer31is 80 μm, or the thickness of the first sub-layer31is 100 μm.

In some embodiments, the thickness of the first sub-layer31is related to the material included in the base and the material included in the reflective particles in the first sub-layer31. In a case where the material of the base in the first sub-layer31includes at least one of acrylic resin, polymethyl methacrylate and PET, and the material of the reflective particles includes at least one of titanium dioxide, zinc oxide and zirconium oxide, the thickness of the first sub-layer31is greater than or equal to 50 μm, and is less than or equal to 100 μm. In this way, not only is it possible to ensure that the first sub-layer31is capable of effectively reflecting light, but also it is possible to ensure that the glass backplane200is light and thin. For example, the thickness of the first sub-layer31is 60 μm, or the thickness of the first sub-layer31is 80 μm, or the thickness of the first sub-layer31is 100 μm.

In some embodiments, as shown inFIGS.2A to5, the reflective layer3further includes a second sub-layer32stacked with the first sub-layer31. In a case where the reflective layer3is disposed at the first side A of the tempered glass substrate1, the second sub-layer32is closer to the tempered glass substrate1than the first sub-layer31.

By providing the second sub-layer32, stiffness of the first sub-layer31may be improved, and thus the first sub-layer31is not easy to deform, and the impact resistance of the glass backplane200may be further improved.

In some embodiments, a material of the second sub-layer32is not limited, as long as the material is capable of improving the stiffness of the first sub-layer31and further improving the impact resistance of the glass backplane200. For example, the material of the second sub-layer32has high mechanical strength and high hardness.

In some examples, the material of the second sub-layer32is one of PET, polypropylene (PP) and polyvinyl chloride (PVC). For example, the material of the second sub-layer32is PET. PET, PP and PVC all have strong mechanical properties, high surface hardness and good heat resistance. By using one of the materials as the material of the second sub-layer32, the obtained second sub-layer32has higher hardness and good impact resistance, thereby providing an effective support for the first sub-layer31and improving the stiffness of the first sub-layer31. Moreover, the second sub-layer32may further strengthen the impact resistance and tear resistance of the tempered glass substrate1, and prevent the tempered glass substrate1from bursting and scattering.

In some embodiments, in a case where the material of the base in the first sub-layer31is PET, and the material of the second sub-layer32is PET, the base of the first sub-layer31is integrated with the second sub-layer32.

In some embodiments, by setting a thickness of the second sub-layer32within an appropriate range, it is possible to avoid that the glass backplane200is not light and thin enough due to a fact that the overall thickness of the glass backplane200is increased due to an excessively large thickness of the second sub-layer32, and it is further possible to avoid an insufficient support for the first sub-layer31due to an excessively small thickness of the second sub-layer32.

For example, the thickness of the second sub-layer32is greater than or equal to 30 μm, and is less than or equal to 150 μm. In this way, not only is it possible to ensure that the second sub-layer32is capable of effectively supporting the first sub-layer31, but also it is possible to ensure that the glass backplane200is light and thin. For example, the thickness of the second sub-layer32is 60 μm, or the thickness of the second sub-layer32is 70 μm, or the thickness of the second sub-layer32is 80 μm.

In some embodiments, the thickness of the second sub-layer32is related to the material thereof. In a case where the material of the second sub-layer32is PET, the thickness of the second sub-layer32is greater than or equal to 30 μm, and is less than or equal to 150 μm. In this way, not only is it possible to ensure that the second sub-layer32is capable of effectively supporting the first sub-layer31, but also it is possible to ensure that the glass backplane200is light and thin. For example, the thickness of the second sub-layer32is 60 μm, or the thickness of the second sub-layer32is 70 μm, or the thickness of the second sub-layer32is 80 μm.

It will be noted that, positions of the first sub-layer31and the second sub-layer32included in the reflective layer3are not limited to the above arrangements. In some other embodiments, the first sub-layer31and the second sub-layer32in the reflective layer3may further be disposed at other positions.

In some embodiments, as shown inFIGS.3to5, the glass backplane200further includes a heat-dissipating layer4. In a case where the light-shielding layer2is disposed on the first side A of the tempered glass substrate1, and the reflective layer3is disposed at the first side A of the light-shielding layer2, the heat-dissipating layer4is disposed between the light-shielding layer2and the reflective layer3. The heat-dissipating layer4is capable of conducting and dissipating heat. Therefore, in the case where the glass backplane200is applied to the backlight module, heat generated by the backlight module in a working process may be effectively dissipated, thereby preventing an excessively high temperature of the backlight module from affecting its normal operations.

In some embodiments, a material of the heat-dissipating layer4is not limited, as long as the material is capable of dissipating heat. For example, the material of the heat-dissipating layer4is a material with a high thermal conductivity.

In some embodiments, the material of the heat-dissipating layer4includes at least one of graphite, copper, aluminum and silver. Graphite, copper, aluminum and silver have high specific heat capacity and good thermal conductivity, and are fast in heat dissipation and absorption. Therefore, heat-dissipating performance of the heat-dissipating layer4may be ensured, and the heat-dissipating layer4is capable of conducting and dissipating heat quickly and effectively. For example, the material of the heat-dissipating layer4is graphite, or the material of the heat-dissipating layer4is silver, or the material of the heat-dissipating layer4is an alloy of copper and silver.

In some embodiments, by setting a thickness of the heat-dissipating layer4within an appropriate range, it is possible to avoid that the glass backplane200is not light and thin enough due to a fact that the overall thickness of the glass backplane200is increased due to an excessively large thickness of the heat-dissipating layer4, and it is further possible to avoid an ineffective heat conduction and dissipation caused by an excessively small thickness of the heat-dissipating layer4.

For example, the thickness of the heat-dissipating layer4is greater than or equal to 50 μm, and is less than or equal to 100 μm. In this way, not only is it possible to ensure that the heat-dissipating layer4is capable of effectively conducting and dissipating heat, but also it is possible to ensure that the glass backplane200is light and thin. For example, the thickness of the heat-dissipating layer4is 60 μm, or the thickness of the heat-dissipating layer4is 80 μm, or the thickness of the heat-dissipating layer4is 100 μm.

In some embodiments, the thickness of the heat-dissipating layer4is related to the material of the heat-dissipating layer4. In a case where the material of the heat-dissipating layer4includes at least one of graphite, copper, aluminum and silver, for example, in a case where the material of the heat-dissipating layer4is graphite, the thickness of the heat-dissipating layer4is greater than or equal to 50 μm, and is less than or equal to 100 μm. In this way, not only is it possible to ensure that the heat-dissipating layer4is capable of effectively conducting and dissipating heat, but also it is possible to ensure that the glass backplane200is light and thin. For example, the thickness of the heat-dissipating layer4is 60 μm, or the thickness of the heat-dissipating layer4is 80 μm, or the thickness of the heat-dissipating layer4is 100 μm.

In some embodiments, a position of the heat-dissipating layer4in the glass backplane200provided by the present disclosure is not limited to the above arrangement. In some other embodiments, the heat-dissipating layer4may further be disposed at other positions. For example, the heat-dissipating layer4is disposed at the second side B of the tempered glass substrate1.

In some embodiments, as shown inFIGS.3to5, the glass backplane200further includes a destaticizing layer5. In a case where the light-shielding layer2is disposed on the first side A of the tempered glass substrate1, and the reflective layer3is disposed at the first side A of the light-shielding layer2, the destaticizing layer5is disposed between the light-shielding layer2and the reflective layer3.

In some examples, in a case where the glass backplane200includes the heat-dissipating layer4, the heat-dissipating layer4and the destaticizing layer5are both disposed between the light-shielding layer2and the reflective layer3, and relative positions of the heat-dissipating layer4and the destaticizing layer5are not limited. For example, as shown inFIG.3, the destaticizing layer5is closer to the light-shielding layer2than the heat-dissipating layer4, or, as shown inFIG.4, the destaticizing layer5is further away from the light-shielding layer2than the heat-dissipating layer4.

In a case where the glass backplane200is applied to the backlight module, and the backlight module and a display panel are applied to a display apparatus, the display panel may generate static electricity during operation of the display apparatus, thereby affecting normal operations of the display panel. The destaticizing layer5is capable of conducting out the static electricity generated by the display panel, thereby preventing the static electricity from affecting the normal operation of the display panel.

In some embodiments, a material of the destaticizing layer5is not limited, as long as the material has strong conductivity and is capable of removing static electricity. For example, the material of the destaticizing layer5is a metal. For example, the material of the electrostatic layer5includes at least one of copper, silver and aluminum. Copper, silver and aluminum all have high conductivity, and are capable of conducting out static electricity and removing static electricity.

In some embodiments, by setting a thickness of the destaticizing layer5within an appropriate range, it is possible to avoid that the glass backplane200is not light and thin enough due to a fact that the overall thickness of the glass backplane200is increased due to an excessively large thickness of the destaticizing layer5, and it is further possible to avoid that the destaticizing layer5is incapable of effectively removing static electricity due to an excessively small thickness of the destaticizing layer5.

For example, the thickness of the destaticizing layer5is greater than or equal to 2 μm, and is less than or equal to 6 μm. In this way, not only is it possible to ensure that the destaticizing layer5is capable of effectively removing ions, but also it is possible to ensure that the glass backplane200is light and thin. For example, the thickness of the destaticizing layer5is 2 μm, or the thickness of the destaticizing layer5is 4 μm, or the thickness of the destaticizing layer5is 6 μm.

In some embodiments, the thickness of the destaticizing layer5is related to the material thereof. In a case where the material of the destaticizing layer5is copper, the thickness of the destaticizing layer5is greater than or equal to 2 μm, and is less than or equal to 6 μm. In this way, not only is it possible to ensure that the destaticizing layer5is capable of effectively removing the ions, but also it is possible to ensure that the glass backplane200is light and thin. For example, the thickness of the destaticizing layer5is 2 μm, or the thickness of the destaticizing layer5is 4 μm, or the thickness of the destaticizing layer5is 6 μm.

In some embodiments, a position of the destaticizing layer5in the glass backplane200provided by the present disclosure is not limited to the above arrangement. In some other embodiments, the destaticizing layer5may further be disposed at other positions. For example, in the case where the reflective layer3is disposed at the first side A of the tempered glass substrate1, the destaticizing layer5is disposed at a side of the reflective layer3facing away from the tempered glass substrate1. Or, the destaticizing layer5is disposed at the second side B of the tempered glass substrate1.

In some embodiments, as shown inFIGS.3to5, the glass backplane200further includes a wear-resistant layer6disposed on the second side B of the tempered glass substrate1.

The wear-resistant layer6is disposed on the second side B of the tempered glass substrate1, so as to be capable of protecting a surface of the second side B of the tempered glass substrate1from being damaged. For example, the wear-resistant layer6is capable of preventing the surface of the tempered glass substrate1from scratching, and preventing fingerprints from being made on the surface of the tempered glass substrate1, thereby ensuring an aesthetic appearance of the glass backplane200.

In some embodiments, a material of the wear layer6is not limited, as long as the material is capable of protecting the tempered glass substrate1. For example, the material of the wear-resistant layer6has high friction resistance.

In some examples, the material of the wear layer6includes one of PET, PP and PVC. For example, the material of the wear layer6includes PET. PET, PP and PVC all have good friction resistance and strong mechanical properties. By using one of the materials as the material of the wear-resistant layer6, it is possible to ensure that the wear-resistant layer6has good friction resistance and high mechanical strength, thereby protecting the tempered glass substrate1and further improving the impact resistance of the tempered glass substrate1.

In some embodiments, by setting a thickness of the wear-resistant layer6within an appropriate range, it is possible to avoid that the glass backplane200is not light and thin enough due to a fact that the overall thickness of the glass backplane200is increased due to an excessively large thickness of the wear-resistant layer6, and it is further possible to avoid that the wear-resistant layer6is incapable of effectively protecting the tempered glass substrate1due to an excessively small thickness of the wear-resistant layer6.

For example, the thickness of the wear-resistant layer6is greater than or equal to 50 μm, and is less than or equal to 100 μm. In this way, not only is it possible to ensure that the wear-resistant layer6is capable of effectively protecting the tempered glass substrate1, but also it is possible to ensure that the glass backplane200is light and thin. For example, the thickness of the wear layer6is 60 μm, or the thickness of the wear layer6is 80 μm, or the thickness of the wear layer6is 100 μm.

In some examples, the thickness of the wear-resistant layer6is related to the material of the wear-resistant layer6. For example, in a case where the material of the wear layer6is PET, the thickness of the wear-resistant layer6is greater than or equal to 50 μm, and is less than or equal to 100 μm. In this way, not only is it possible to ensure that the wear-resistant layer6is capable of effectively protecting the tempered glass substrate1, but also it is possible to ensure that the glass backplane200is light and thin. For example, the thickness of the wear layer6is 60 μm, or the thickness of the wear layer6is 80 μm, or the thickness of the wear layer6is 100 μm.

It will be noted that, in a case where film layers included in the backlight module200except the wear-resistant layer6are disposed at the second side B of the tempered glass substrate1, for example, in a case where the light-shielding layer2is disposed on the second side B of the tempered glass substrate1, and the first side A of the light-shielding layer2is closer to the tempered glass substrate1than the second side B, the wear-resistant layer6is disposed on the second side B of the light-shielding layer2. That is to say, the wear-resistant layer6is disposed at the second side B of the tempered glass substrate1and is located on an outermost side of the backlight module200to protect the tempered glass substrate1and other film layers.

In some embodiments, as shown inFIG.5, the glass backplane200further includes an adhesive layer disposed between the light-shielding layer2and the reflective layer7.

For example, in a case where the glass backplane200includes the light-shielding layer2and the reflective layer3, the adhesive layer7is disposed on the first side A of the light-shielding layer2(i.e., a side of the light-shielding layer2that is not in contact with the tempered glass substrate1), so that the adhesive layer7enables the light-shielding layer2and the reflective layer3to be more tightly bonded, thereby avoiding a peeling-off phenomenon caused by an insecure bonding between the light-shielding layer2and the reflective layer3. For example, in the case where the glass backplane200further includes the heat-dissipating layer4, the adhesive layer7is disposed on the first side A of the light-shielding layer2(i.e., the side of the light-shielding layer2that is not in contact with the tempered glass substrate1), so that the adhesive layer7enables the light-shielding layer2and the heat-dissipating layer4to be tightly bonded, thereby avoiding a peeling-off phenomenon caused by an insecure bonding between the light-shielding layer2and the heat-dissipating layer4.

For example, in a case where the glass backplane200further includes the heat-dissipating layer4and the destaticizing layer5, with the destaticizing layer5being further away from the tempered glass substrate1than the heat-dissipating layer4, the adhesive layer7is disposed on the first side A of the light-shielding layer2(i.e., the side of the light-shielding layer2that is not in contact with the tempered glass substrate1), so that the adhesive layer7enables the light-shielding layer2and the heat-dissipating layer4to be tightly bonded, thereby avoiding a peeling-off phenomenon caused by an insecure bonding between the light-shielding layer2and the heat-dissipating layer4. Or, in a case where the glass backplane200further includes the heat-dissipating layer4and the destaticizing layer5, with the destaticizing layer5being closer to the tempered glass substrate1than the heat-dissipating layer4, the adhesive layer7is disposed on the first side A of the light-shielding layer2(i.e., the side of the light-shielding layer2that is not in contact with the tempered glass substrate1), so that the adhesive layer7enables the light-shielding layer2and the destaticizing layer5to be tightly bonded, thereby avoiding a peeling-off phenomenon caused by an insecure bonding between the light-shielding layer2and the destaticizing layer5.

In some embodiments, a material of the adhesive layer7is not limited, as long as the material is capable of playing an adhesive role. For example, the material of the adhesive layer7has high adhesiveness.

In some examples, the material of the adhesive layer7is acrylate. Acrylate is widely used as an adhesive due to a strong hydrogen bonding of its ester group. An acrylate adhesive has characteristics such as a high strength, impact resistance, good weather resistance, being capable of be bonded to an oil surface, and the like. The acrylate adhesive has a wide application range, and enables the film layers in the glass backplane200to be tightly bonded, and is especially applicable to the case where the material of the light-shielding layer2is ink (e.g., the high-temperature ink). Since the acrylate adhesive has the characteristic of being capable of being binded to the oil surface, the acrylate adhesive enables the light-shielding layer2and other film layers to be tightly bonded and not to fall off easily.

In some embodiments, by setting a thickness of the adhesive layer7within an appropriate range, it is possible to avoid that the glass backplane200is not light and thin enough due to a fact that the overall thickness of the glass backplane200is increased due to an excessively large thickness of the adhesive layer7, and it is further possible to avoid an insufficient bonding by the adhesive layer7caused by an excessively small thickness of the adhesive layer7.

For example, the thickness of the adhesive layer7is greater than or equal to 50 μm, and is less than or equal to 100 μm. In this way, not only is it possible to ensure that the adhesive layer7effectively plays the adhesive role, but also it is possible to ensure that the glass backplane200is light and thin. For example, the thickness of the adhesive layer7is 50 μm, or the thickness of the adhesive layer7is 70 μm, or the thickness of the adhesive layer7is 100 μm.

In some embodiments, the thickness of the adhesive layer7is related to the material thereof. For example, in a case where the material of the adhesive layer7is acrylate, the thickness of the adhesive layer7is greater than or equal to 50 μm, and is less than or equal to 100 μm. In this way, not only is it possible to ensure that the adhesive layer7effectively plays the adhesive role, but also it is possible to ensure that the glass backplane200is light and thin. For example, the thickness of the adhesive layer7is 50 μm, or the thickness of the adhesive layer7is 70 μm, or the thickness of the adhesive layer7is 100 μm.

The possible positions, functions, materials and thickness ranges of the film layers in the glass backplane200are described above, and an overall introduction of the glass backplane200will be given below by taking an overall structure of the glass backplane200as an example.

In some embodiments, as shown inFIG.5, the glass backplane200includes the wear-resistant layer6, the tempered glass substrate1, the light-shielding layer2, the adhesive layer7, the heat-dissipating layer4, the destaticizing layer5and the reflective layer3that are sequentially stacked. The wear-resistant layer6is disposed on the second side B of the tempered glass substrate, and the light-shielding layer2, the adhesive layer7, the heat-dissipating layer4, the destaticizing layer5and the reflective layer3are sequentially stacked at the first side A of the tempered glass substrate1. The reflective layer3includes the first sub-layer31and the second sub-layer32that are stacked, with the second sub-layer32being closer to the tempered glass substrate1than the first sub-layer31.

On a basis of the above positional relationship among the film layers, the materials and the thicknesses of the film layers are introduced as follows.

For example, the tempered glass substrate1is obtained by tempering the glass base. The selected glass base is of the float glass, with a thickness of greater than or equal to 3 mm and less than or equal to 8 mm. For example, the thickness of the glass base is 5 mm.

For example, the material of the light-shielding layer2is ink, such as the high-temperature ink, with a thickness of greater than or equal to 29.5 μm and less than or equal to 30.5 μm. For example, the thickness of the light-shielding layer2is 30 μm.

For example, the material of the adhesive layer7is acrylate, with a thickness of greater than or equal to 50 μm and less than or equal to 100 μm. For example, the thickness of the adhesive layer7is 70 μm.

For example, the material of the heat-dissipating layer is graphite, with a thickness of greater than or equal to 50 μm and less than or equal to 100 μm. For example, the thickness of the heat-dissipating layer4is 70 μm.

For example, the material of the destaticizing layer5is copper, with a thickness of greater than or equal to 2 μm and less than or equal to 6 μm. For example, the thickness of the destaticizing layer5is 2 μm.

For example, the material of the second sub-layer32included in the reflective layer3is PET, with a thickness of greater than or equal to 30 μm and less than or equal to 150 μm. For example, the thickness of the second sub-layer32is 70 μm. The first sub-layer31included in the reflective layer3includes the base and the reflective particles. The material of the base is acrylic resin, and the material of the reflective particles includes titanium dioxide and zinc oxide. The thickness of the first sub-layer31is greater than or equal to 50 μm, and is less than or equal to 100 μm. For example, the thickness of the first sub-layer31is 70 μm.

For example, the material of the wear-resistant layer6is PET, with a thickness of greater than or equal to 50 μm and less than or equal to 100 μm. For example, the thickness of the wear-resistant layer6is 70 μm.

As shown inFIG.6, some embodiments of the present disclosure provide a method of manufacturing a glass base. The method includes: S1to S4.

In S1, a glass base is provided, and two opposite sides of the glass are a first side and a second side.

It will be noted that, in the above step, the provided glass base is the one processed with a specific size. For example, before the glass base is provided, a piece of glass needs to be selected, and subjected to processes such as cutting, edging, perforating and chamfering according to a required size to obtain the glass base. In some embodiments, the selected glass is float glass, such as low-iron float glass, which has characteristics such as a good optical performance, good flatness, compact structure, being easy to cut, not easy to break and the like, and is an ideal material for manufacturing the glass base. For example, a thickness of the obtained glass base is greater than or equal to 3 mm, and is less than or equal to 8 mm.

In S2, a light-shielding layer2is formed on a surface of the first side of the glass base. Two opposite sides of the light-shielding layer2are a first side A and a second side B, and the second side B of the light-shielding layer2is closer to the glass base than the first side A of the light-shielding layer2.

In some embodiments, the light-shielding layer2is formed on the surface of the first side of the glass base through a screen printing process. For example, a material of the light-shielding layer2is ink, such as high-temperature ink. In a case where the material of the light-shielding layer2is the high-temperature ink, a thickness of the light-shielding layer2is greater than or equal to 29.5 μm, and is less than or equal to 30.5 μm.

In S3, the glass base on which the light-shielding layer2is formed is tempered, so as to transform the glass base into a tempered glass substrate1.

In the above step, for example, a manner of tempering the glass base with the light-shielding layer2formed thereon is: placing the glass base with the light-shielding layer2formed thereon into a tempering furnace, and heating the glass base to a temperature of 700° C. and for a certain period of time, followed by cooling the glass base by rapidly blowing cold air. In this way, a glass structure of the glass base is changed, a compressive stress is formed on a surface of the glass base, and impact resistance is improved, thereby forming the tempered glass substrate1. Moreover, in the case where the material of the light-shielding layer2is the high-temperature ink, interaction between the high-temperature ink and the glass base is enhanced after the heating and cooling processes in the tempering process, and an adhesive force of the light-shielding layer2is improved, thereby making the light-shielding layer2be tightly bonded to the tempered glass substrate1and not easy to fall off.

In some embodiments, in the steps of tempering the glass base with the light-shielding layer2formed thereon, heating time and cooling time are set to be related to the thickness of the glass base, so that it is possible to ensure that the compressive stress on the surface of the glass base is enhanced, and a tempered glass substrate1with strong impact resistance is formed. For example, in a case where the thickness of the glass base is greater than or equal to 3 mm, and is less than or equal to 5 mm, the time for which the glass base with the light-shielding layer2formed thereon is heated at the temperature of 700° C. is in a range of 200 s to 240 s, and the cooling time is in a range of 120 s to 150 s. In a case where the thickness of the glass base is greater than or equal to 6 mm, and is less than or equal to 8 mm, the time for which the glass base with the light-shielding layer2formed thereon is heated at the temperature of 700° C. is in a range of 450 s to 480 s, and the cooling time is in a range of 300 s to 330 s.

In S4, a reflective layer3is formed at the first side A of the light-shielding layer2.

In some embodiments, as shown inFIG.7A, S4includes S41and S42.

In S41, a second sub-layer32is formed on the first side A of the light-shielding layer2. Two opposite sides of the second sub-layer32are a first side A and a second side B, and the second side B of the second sub-layer32is closer to the light-shielding layer2than the first side A of the second sub-layer32.

For example, the second sub-layer32is formed on a surface of the first side A of the light-shielding layer2through a deposition process.

In some examples, a material of the second sub-layer32is polyethylene glycol terephthalate (PET), with a thickness of greater than or equal to 30 μm and less than or equal to 150 μm. For example, the thickness of the second sub-layer32is 70 μm.

In S42, a first sub-layer31is formed on a surface of the first side A of the second sub-layer32, and the first sub-layer31includes a base and reflective particles dispersed in the base.

For example, the first sub-layer31is formed on the surface of the first side A of the second sub-layer32through a deposition process. As a possible implementation, the reflective particles are dispersed in the base to form a mixture of the reflective particles and the base before the deposition process, and then the mixture of the reflective particles and the base is deposited on the surface of the first side A of the second sub-layer32through the deposition process to form the first sub-layer31.

In some examples, a material of the base in the first sub-layer31includes at least one of acrylic resin, polymethyl methacrylate and PET. A material of the reflective particles in the first sub-layer31includes at least one of titanium dioxide, zinc oxide and zirconium oxide. A thickness of the first sub-layer31is greater than or equal to 50 μm, and is less than or equal to 100 μm. For example, the thickness of the first sub-layer31is 70 μm.

In some other embodiments, as shown inFIG.78, S4includes S41′ to S43′.

In S41′, the second sub-layer32is provided. The two opposite sides of the second sub-layer32are the first side A and the second side B.

In some examples, the material of the second sub-layer32is PET, with a thickness of greater than or equal to 50 μm and less than or equal to 100 μm. For example, the thickness of the second sub-layer32is 70 μm.

In S42′, the first sub-layer31is formed on the surface of the first side A of the second sub-layer32, and the first sub-layer31includes the base and the reflective particles dispersed in the base.

As a possible implementation, the reflective particles are dispersed in the base to form the mixture of the reflective particles and the base, and then the mixture of the reflective particles and the base is coated on the surface of the first side A of the second sub-layer32to form the first sub-layer31.

In S43′, the reflective layer composed of the first sub-layer31and the second sub-layer32is bonded to the surface of the first side A of the light-shielding layer2through an adhesive, with the second side B of the second sub-layer32being closer to the light-shielding layer2than the first side A of the second sub-layer32.

For example, with the adhesive being coated on a surface of the second side B of the second sub-layer32to form an adhesive layer7, the reflective layer3composed of the first sub-layer31and the second sub-layer32can be bonded to the surface of the first side A of the light-shielding layer2through the adhesive layer7. Or, with the adhesive being coated on the surface of the first side A of the light-shielding layer2to form the adhesive layer7, the second side B of the second sub-layer32can be bonded to the surface of the first side A of the light-shielding layer2through the adhesive layer7.

It will be noted that, for a preparing manner in which the reflective layer3being bonded to the surface of the first side A of the light-shielding layer2through the adhesive in S41′ to S43′, S41′ to S42′ (i.e., the steps of preparing the reflective layer3) may be performed simultaneously with S1to S3(i.e., the steps of preparing the light-shielding layer2on the glass base and tempering the glass base), and then the prepared reflective layer3is bonded to the surface of the first side A of the light-shielding layer2, which may improve manufacturing efficiency and save time.

In some embodiments, the method of manufacturing the glass backplane further includes: cleaning the surface of the glass base before S2.

For example, the surface of the glass base is brushed in a rolling manner to remove debris on the surface, and is ultrasonically cleaned by sequentially using cleaning agents such as acetone, isopropanol and deionized water for 10 min to 15 min, and then hot air is blown to the surface of the glass base to dry the surface of the glass base.

In some embodiments, the method of manufacturing the glass backplane further includes steps of forming a heat-dissipating layer4, a destaticizing layer5and a wear-resistant layer6, all of which can be formed by using the deposition process, and a sequence of forming the film layers is determined according to actual situations, and is not limed in the present disclosure.

An overall introduction of an embodiment of the method of manufacturing the glass backplane will be given below with the glass backplane200shown inFIG.5as an example.

In S1, the glass base is provided.

In S2, the light-shielding layer2is formed on the surface of the first side of the glass base. The two opposite sides of the light-shielding layer2are the first side A and the second side B, with the second side B of the light-shielding layer2being closer to the glass base than the first side A of the light-shielding layer2.

In S3, the glass base with the light-shielding layer2formed thereon is tempered, so as to transform the glass base into the tempered glass substrate1. Two opposite sides of the tempered glass substrate1are a first side A and a second side B, with the second side B of the light-shielding layer2being closer to the tempered glass substrate1than the first side A of the light-shielding layer2.

As for a specific introduction of S1to S3, reference may be made to the above description.

In S41′, the second sub-layer32is provided. The two opposite sides of the second sub-layer32are the first side A and the second side B.

In S42′, the first sub-layer31is formed on the surface of the first side A of the second sub-layer32, and the first sub-layer31includes the base and the reflective particles dispersed in the base.

As for a specific introduction of S41′ and S42′, reference may be made to the above description.

In S421′, the destaticizing layer5is formed on the surface of the second side B of the second sub-layer32.

For example, the destaticizing layer5is formed on the surface of the second side B of the second sub-layer32through the deposition process.

In some examples, a material of the destaticizing layer5is a metal such as copper, with a thickness of greater than or equal to 2 μm and less than or equal to 6 μm. For example, the thickness of the destaticizing layer5is 2 μm.

In S422′, the heat-dissipating layer4is formed on a surface of aside (i.e., a first side A) of the destaticizing layer5away from the first sub-layer31.

For example, the heat-dissipating layer4is formed on the surface of the side of the destaticizing layer5away from the first sub-layer31through the deposition process.

For example, a material of the heat-dissipating layer4includes at least one of graphite, copper, aluminum and silver. For example, the material of the heat-dissipating layer is graphite. A thickness of the heat-dissipating layer4is greater than or equal to 50 μm, and is less than or equal to 100 μm. For example, the thickness of the heat-dissipating layer4is 70 μm.

It will be noted that, S1to S3and S41′ to S422′ are two separate manufacturing processes. In some embodiments, S1to S3and S41′ to S422′ are performed simultaneously, which may improve the manufacturing efficiency of the glass backplane.

In S43′, a stacked structure formed by the reflective layer3composed of the first sub-layer31and the second sub-layer32, the destaticizing layer5and the heat-dissipating layer4is bonded to the surface of the first side A of the light-shielding layer2through the adhesive.

In the above steps, for example, the adhesive is coated on the surface of the first side A of the light-shielding layer2to form the adhesive layer7, and then the stacked structure formed by the reflective layer3, the destaticizing layer5and the heat-dissipating layer4is transferred onto the adhesive layer7, with the heat-dissipating layer4being in contact with the adhesive layer7, thereby bonding the stacked structure to the surface of the first side A of the light-shielding layer2through the adhesive.

For example, a material of the adhesive layer7is acrylate, with a thickness of greater than or equal to 50 μm and less than or equal to 100 μm. For example, the thickness of the adhesive layer7is 70 μm.

In S5, the wear-resistant layer6is formed on a surface of the second side B of the tempered glass substrate1.

For example, the wear-resistant layer6is formed on the surface of the second side B of the second sub-layer32through the deposition process.

For example, the material of the wear-resistant layer6is PET, with a thickness of greater than or equal to 50 μm and less than or equal to 100 μm. For example, the thickness of the wear layer6is 70 μm.

The glass backplane200shown inFIG.5is manufactured through the above method of manufacturing the glass backplane.

For example, a thickness of each film layer mentioned in some embodiments of the present disclosure refers to an average of thicknesses at respective positions of the film layer in a direction perpendicular to a plane where the film layer is located. Or, the thickness of each film layer mentioned in some embodiments of the present disclosure refers to a maximum thickness or a minimum thickness in the thicknesses at respective positions of the film layer in the direction perpendicular to the plane where the film layer is located.

Some embodiments of the present disclosure provide a backlight module including the glass backplane200provided in some embodiments of the present disclosure. For convenience of description, taking the glass backplane200shown inFIGS.2A to5as an example, a surface of the glass backplane200provided with the reflective layer3is referred to as a backlight surface, and another surface thereof is referred to as a design surface. In a case where the backlight module is applied to a display device, the backlight surface of the glass backplane200is configured to face the display panel.

In some embodiments, as shown inFIG.8A, the backlight module is a side-type backlight module300, which includes a glass backplane200, a light source20, a light guide plate30, a reflective sheet40, an optical film50, a heat-dissipating plate60and a frame70.

The light source20is disposed at an end of the light guide plate30and is configured to emit light to provide the light to the display panel. The reflective sheet40is disposed at the backlight side of the glass backplane200, and is configured to reflect the light. The light guide plate30is disposed on a side of the reflective sheet40facing away from the glass backplane200, and is configured to convert the light emitted by the light source20into a surface light source. The optical film50(e.g., the optical film50including a diffusion sheet, a prism sheet and a brightness enhancement sheet) is disposed on a side of the light guide plate30facing away from the glass backplane200, and functions to homogenize light and converge large-angle light for a front observation. The heat-dissipating plate60is disposed at a side of the light source20, and is configured to dissipate heat. The frame70is disposed on a periphery of the backlight module, and is configured to fix the components included in the backlight module.

A process of providing light by the side-type backlight module300is roughly as follows. The light source20emits light, and then the light enters an interior of the light guide plate30from an end of the light guide plate30, and is guided to an opposite end of the light guide plate30from the end of the light guide plate30after the light is totally reflected, refracted, scattered, or reflected in the interior of the light guide plate30. Then, the light exits uniformly from a side of the light guide plate30facing away from the glass backplane200, and is directed to the optical film50. Finally, the light passes through the optical film50and exits to provide required backlight for the display panel after being homogenized and converged by the optical film50. In the above working process, the heat-dissipating plate60functions to dissipate heat, so as to prevent excessive heat generated by the light source20in a light-emitting process from affecting normal operations of the side-type backlight module300.

In the side-type backlight module300, the backplane200is configured to support and protect the light guide plate30. In a case where no reflective sheet40is disposed between the backplane200and the light guide plate30, the backplane200may further have a reflective function, i.e., re-reflect light emitted from a side of the light guide plate30facing the backplane200back to the interior of the light guide plate30.

In some other embodiments, the backlight module is a direct-type backlight module. Referring toFIG.88, the direct-type backlight module300′ includes a glass backplane200, alight source20′, a diffusion plate30′, a frame40′ and an optical film50′.

The light source20′ is disposed on a backlight side of the glass backplane200and is configured to provide light. Under support of the frame40′, there is a certain distance between the diffusion plate30′ and the glass backplane200. For example, the distance is a light-mixing distance, and the diffusion plate30′, the glass backplane200and the frame40′ together form a chamber. For example, the chamber is a light-mixing chamber for mixing light. The diffusion plate30′ is configured to uniformly disperse light. The optical film50′ (e.g., the optical film50′ including a prism sheet and a brightness enhancement sheet) is disposed on a side of the diffusion plate30′ facing away from the glass backplane200, and is configured to enhance brightness of emitted light.

A working process of the direct-type backlight module300′ described above is as follows. The light source20′ emits light, and the light is mixed in the light-mixing chamber. A part of the light directly enters the diffusion plate30′, and a part of the light entering the backplane200enters the diffusion plate30′ after being reflected by the backplane200. Then, the light enters the optical film50′ from the diffusion plate30′ after being uniformly dispersed by the diffusion plate30′. Finally, the light passes through the optical film50′ and is directed to an exterior of the direct-type backlight module100to provide light with high uniformity and high luminance for the display panel after being homogenized and converged by the optical film50′.

In the direct-type backlight module300′, the glass backplane200is configured to support and protect the light source20′. The glass backplane200′ further has a reflective function, i.e., reflects light emitted by the light source20′ and directed to the backplane10′ to the diffusion plate30′.

In the side-type backlight module300and the direct-type backlight module300′ described above, the glass backplane200further has strong deformation resistance, low light transmittance and certain light reflection performance with advantages of being good in flatness, good weather resistance, not easy to expand and deform, light and thin, free of the mold opening and the like. Therefore, an overall flatness of the backlight module may be improved, with a reduced overall thickness, less difficulty in a manufacturing process, saved costs and improved deformation resistance of the backlight module. Moreover, since the glass backplane200provided in the present disclosure overcomes disadvantages of fragility and light transmission of glass, the glass backplane may be widely applied to the backlight module.

As shown inFIG.9, some embodiments of the present disclosure further provide a display apparatus1000including the backlight module provided in some embodiments of the present disclosure (the side-type backlight module300or the direct-type backlight module300′), and a display panel400stacked with the backlight module and disposed on a light-emitting side of the backlight module300(300′).

In some embodiments, the display panel400mentioned above includes an array substrate401and an opposite substrate403that are disposed opposite to each other, and a liquid crystal layer402disposed between the array substrate401and the opposite substrate403.

For example, a working process of the display apparatus is as follows. The backlight module300(300′)) provides a backlight, light is irradiated onto the display panel400, and meanwhile liquid crystal molecules in the liquid crystal layer402are deflected under action of a voltage to control whether the light is emitted from a front surface of the display panel in which a deflected degree of the liquid crystal molecules is related to a magnitude of the applied voltage, thereby controlling intensity of the light emitted from the front surface of the display panel. Each pixel on an entire display panel may determine the intensity of the emitted light separately, thereby generating an image.

The display apparatus1000provided in the embodiments of the present disclosure includes the backlight module provided in the embodiments of the present disclosure. Therefore, the display apparatus has good performance, an aesthetic appearance, a light and thin body, and has same technical effects as the backlight module. For example, an overall thickness of the display apparatus1000may be within 10 mm.

In some examples, the display apparatus may be a fringe field switching (FFS) liquid crystal display apparatus, an in-plane switching (IPS) liquid crystal display apparatus, or an advanced super dimension switch (ADS) liquid crystal display apparatus.

In addition, the display apparatus is a product with a display function such as a television, a cellphone, a tablet computer, a notebook computer, a display, a digital photo frame or a navigator, which is not limited in the present disclosure.

The forgoing descriptions are merely specific implementations of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art could conceive of changes or replacements within the technical scope of the present disclosure, which shall all be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to the protection scope of the claims.
