CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 U.S.C. § 119 (a) to Chinese Patent Application No. 202310636191.X, filed May 31, 2023, the entire disclosure of which is incorporated herein by reference.

TECHNICAL FIELD

This disclosure relates to the field of display technology, and in particular to a display panel and a display device.

BACKGROUND

With continuous development of the display industry and widespread application of display panels, requirements of users for multi-functionalization of the display panels are also increasing. For example, with increasing attention of the user to privacy, in a public scenario or some special scenarios, when the user uses a display product such as a mobile phone, a tablet computer, or a notebook computer, the user may need the display product to implement a privacy function to protect privacy.

However, if a display effect of the display panel is limited to a privacy state, and intelligent adjustment of a display view angle cannot be satisfied, a viewing experience of the user will also be reduced to a large extent when switching usage scenarios.

A display panel10is provided in an embodiment of the present disclosure. The display panel10has a light-exiting surface11. The display panel10includes a color film substrate12and a privacy film13. The color film substrate12includes a carrier plate121and multiple color resist units122. The carrier plate121has a first surface1211and a second surface1212opposite to the first surface1211. The first surface1211is closer to the light-exiting surface11than the second surface1212. The multiple color resist units122are arranged at intervals on the carrier plate121and are away from the first surface1211. The privacy film13includes multiple privacy units131disposed corresponding to the multiple color resist units122. Different privacy units131correspond to different color resist units122. Each of the multiple privacy units131has a transparent film1311and multiple charged particles1312. The transparent film1311covers a corresponding color resist unit122and part of the transparent film1311is located in at least part of a gap123between two adjacent color resist units122. The transparent film1311defines a cavity131f, and the multiple charged particles1312are accommodated in the cavity131f. The privacy film13has a first state and a second state. When the privacy film13is in the first state, the multiple charged particles1312in the privacy unit131are attached to one end of the transparent film1311close to the corresponding color resist unit122and exceed a surface of the corresponding color resist unit122by a first height H1. When the privacy film13is in the second state, the multiple charged particles1312in the privacy unit131are attached to said one end of the transparent film1311close to the corresponding color resist unit122and exceed the surface of the corresponding color resist units122by a second height H2, and the second height H2is greater than the first height H1. When the privacy film13is in the first state or the second state, at least part of each of the multiple charged particles1312is disposed in the gap123between the two adjacent color resist units122.

The display panel10may be, but is not limited to, a Liquid Crystal (LC) display panel, an Organic Light-Emitting Diode (OLED) display panel, a field emission display panel, a plasma display panel, a curved panel, or the like. The OLED display panel may further include a polarizer-less (i.e., Color On Encapsulation, COE) panel. It can be understood that the function type of the display panel10shall not be construed as a limitation to the display panel10provided in this implementation.

The image display can be performed on the light-exiting surface11in the display panel10. The color film substrate12can perform color filtering on the light emitted from the display panel10and greatly improve the color performance of the display panel10.

The material of the carrier plate121may be, but is not limited to, glass, a transparent organic layer, or other materials. The carrier plate121has a first surface1211and a second surface1212opposite to the first surface1211. The first surface1211is closer to the light-exiting surface11than the second surface1212, and in other words, the first surface1211is close to the light-exiting surface11, and the first surface1211may, but is not limited to, directly face the light-exiting surface11.

Optionally, the color resist unit122may be a Red (R) color resist, a Green (G) color resist, a Blue (B) color resist, or color resists of other colors. The multiple color resist units122may include color resists of multiple colors, which is not limited in the present disclosure.

The multiple color resist units122are arranged at intervals on the carrier plate121and are away from the first surface1211, and are configured to filter the light of the display panel10.

Optionally, the number of color resist units122may be two, three, four, or other number. A distance between two adjacent color resist units122may be equal or unequal. The multiple color resist units122may be, but are not limited to, arranged in an array on the carrier plate121.

Optionally, the color resist unit122may be directly disposed on the carrier plate121or be indirectly disposed on the carrier plate121. In the schematic diagram of this implementation, for example, the color resist unit122is indirectly disposed on the carrier plate121through the privacy film13.

Optionally, the number of privacy units131may be, but is not limited to, two, three, four, or other number. Two adjacent privacy units131may, but are not limited to, be spaced apart from or abut against each other. In the schematic diagram of this implementation, for example, the two adjacent privacy units131abut against each other.

Optionally, the multiple privacy units131may be arranged in an array on the carrier plate121, and the number of privacy units131may be equal to the number of color resist units122.

The privacy film13may be disposed on the second surface1212of the carrier plate121. Specifically, the second surface1212may be a flat surface, or the second surface1212may define a recess1213recessed towards the light-exiting surface11of the display panel10. The privacy unit131may have one end accommodated in the recess1213, and the other end carrying the color resist unit122. According to the display panel10provided in this implementation, the privacy film13is disposed on the carrier plate121, and compared to traditional designs of a privacy assembly on the display panel alone, due to the structure of the privacy film13provided in this implementation, the display panel10has a privacy function, and the thickness of the display panel10is also increased as small as possible or is not additionally increased, so that the display panel10can meet the design requirements of lightness and thinness.

The multiple privacy units131are disposed corresponding to the multiple color resist units122, and different privacy units131correspond to different color resist units122. Specifically, the privacy unit131may be disposed at one side of the color resist unit122close to the light-exiting surface11, and the privacy unit131may cover a surface of the color resist units122close to the light-exiting surface11.

The privacy unit131may be, but is not limited to, designed to have a structure similar to a capsule. The privacy unit131has a transparent film1311and multiple charged particles1312.

Optionally, the transparent film1311may be made of a colloid or other composite materials. When the transparent film1311is made of a colloid, such as, a gelatin, a silica sol, or a gum, the transparent film1311can meet requirements of mechanical strength and flexibility at the same time, and can be used for a flexible display panel10.

The transparent film1311cooperatively define the cavity131f, and the multiple charged particles1312may be accommodated in the cavity1. Optionally, the shape of the cavity131fmay be a cylinder, or an approximate cylinder, a cube, or other shapes.

Optionally, in an implementation of the present disclosure (FIG.8), the cavity131fof the transparent film1311may also be filled with a transparent liquid, thereby facilitating the movement of the multiple charged particles1312.

The charged particle1312may be made of carbon black or other dark materials, and charges are adsorbed by the charged particle1312through modification or other processes. When the light in the display panel10irradiates the charged particle1312, the charged particle1312may, but is not limited to, block or reduce the passage of the light through adsorption or reflection.

Further, in other implementations of the present disclosure (FIG.9), a surface of the charged particle1312may also be coated with a reflective coating for reflecting light, thereby reducing the loss of light emitted from the color resist units, so that the display panel has the privacy function, and it is ensured that optical efficiency of the display panel is not reduced, thereby improving the display yield of the display panel.

The transparent film1311covers the color resist unit122. Specifically, the transparent film1311may cover a surface of the color resist unit122close to the light-exiting surface11, and the transparent film1311may also partially or completely cover a peripheral side surface of the color resist unit122.

Part of the transparent film1311is located in at least part of the gap123between two adjacent color resist units122, and the transparent film1311may be disposed around the peripheral side surface of the color resist unit122, so that the charged particles1312in the cavity131fcan also be distributed in the gap123, and the charged particles1312can be disposed around the peripheral side surface of the color resist unit122. On one hand, when privacy is not necessary for the display panel10, the charged particles1312can be accommodated in the gap123between the two adjacent color resist units122, thereby not affecting the normal light-exiting of the color resist units122, so that the display panel10has multiple function states, such as a privacy state, a non-privacy state, etc. On the other hand, since the charged particles1312each have a function of blocking light transmission, the charged particles1312can be densely distributed in the gap123between the two adjacent color resist units122, thereby replacing a black matrix in the display panel10and simplifying the technological manufacturing process of the display panel10.

Optionally, the privacy unit131may be provided with an electrode1315. When the electrode1315is loaded with an electrical signal, the charged particles1312will move in the cavity131funder the attraction of the electrode1315, and the charged particles1312may have different distribution states in the cavity131faccording to different cases in which the electrode1315is loaded with the electrical signal.

When the charged particles1312have different distribution states in the cavity131f, the privacy film13and the display panel10may also have different viewing angle states. Specifically, the privacy film13may, but is not limited to, have a first state and a second state, where the first state may be a sharing state, and the second state may be a privacy state.

When the privacy film13is in the first state, that is, when the display panel10is in the sharing state, the multiple charged particles1312in the privacy unit131are attached to one end of the transparent film1311close to the color resist unit122and exceed the surface of the color resist unit122by a first height H1. Specifically, the first height H1may be, but is not limited to, a maximum value among distances between surfaces of the charged particle1312and a plane on which the surface of the color resist unit122close to the light-exiting surface11is located.

When the privacy film13is in the second state, that is, when the display panel10is in the privacy state, the multiple charged particles1312in the privacy unit131are attached to one end of the transparent film1311close to the color resist unit122and exceed the surface of the color resist unit122by a second height H2. Specifically, the second height H2may be, but is not limited to, a maximum value among distances between surfaces of the charged particles1312and the plane on which the surface of the color resist unit122close to the light-exiting surface11is located.

It can be understood that the first height H1and the second height H2each are a height defined by the multiple charged particles1312together, and are not a height of a single charged particle1312.

The second height H2is greater than the first height H1, so that when the privacy film13is in the second state, part of the light emitted from the color resist unit122to the light-exiting surface11is blocked by the charged particles1312, so that an angle at which the light is emitted to the light-exiting surface11is limited, and a viewing angle of the display panel10is narrowed. Therefore, images on the display panel10can be normally viewed from a front viewing angle, but cannot be normally viewed from a side viewing angle, so that the display panel10is in the privacy state.

However, when the privacy film13is in the first state, the light emitted from the color resist unit122to the light-exiting surface11may not be blocked by the charged particles1312, or compared to the privacy film13being in the second state, the light emitted from the color resist unit122to the light-exiting surface11may be less blocked by the charged particles1312, so that compared to the privacy film13being the second state, the angle at which the light is emitted to the light-exiting surface11is increased, and the viewing angle of the display panel10is increased.

Further, in an implementation (FIG.10) of the present disclosure, when the light emitted from the color resist unit122to the light-exiting surface11is not blocked by the charged particles1312, that is, when no charged particle1312exceed the surface of the color resist unit122close to the light-exiting surface11, the images on the display panel10can be normally viewed from various viewing angles, so that the display panel10is in a normal display state.

Further, when the privacy film13is in the first state or the second state, at least part of each of the multiple charged particles1312is at least partially disposed in the gap123between the two adjacent color resist units122, so that a design of a black matrix in a traditional display panel can be replaced, or a black matrix can be completely replaced, thereby simplifying the manufacturing process of the display panel10.

To sum up, the display panel10provided in this implementation includes the color film substrate12and the privacy film13. The color film substrate12includes the carrier plate121and the multiple color resist units122. The privacy film13includes multiple privacy units131, and the multiple privacy units131are disposed corresponding to the multiple color resist units122. In other words, the privacy film13is disposed in the color film substrate12, and compared to the traditional designs of the privacy assembly on the display panel alone, the privacy film13does not increase the thickness of the display panel10additionally, so that the display panel10is designed to be light and thin. In addition, the privacy film13has the first state and the second state. When the privacy film13is in the first state, the multiple charged particles1312in the privacy unit131are attached to one end of the transparent film1311close to the color resist unit122and exceed the surface of the color resist unit122by the first height H1. When the privacy film13is in the second state, the multiple charged particles1312in the privacy unit131are attached to one end of the transparent film1311close to the color resist unit122and exceed the surface of the color resist units122by the second height H2, and the second height H2is greater than the first height H1, so that the display panel10has different display viewing angles, and with adjustment of distribution states of the multiple charged particles1312, the display panel10can have a full-viewing-angle display state, and the display panel10can flexibly switch between the privacy state and the normal display state. Furthermore, the multiple charged particles1312are at least partially disposed in the gap123between the two color resist units122, so that the design of the black matrix in the traditional display panel can be replaced with the aid of the multiple charge particles1312, thereby simplifying the technological manufacturing process of the display panel10.

Reference can be made toFIG.2,FIG.11, andFIG.14, whereFIG.11is a schematic cross-sectional structural diagram of a privacy unit in an embodiment of the present disclosure, andFIG.14is a schematic cross-sectional structural diagram of a privacy unit and a color resist unit in yet another embodiment of the present disclosure. The transparent film1311includes a first film-portion131aand a second film-portion131b. The first film-portion131ais attached to the surface of the color resist unit122close to the light-exiting surface11. The second film-portion131band a peripheral edge of the first film-portion131aare connected in a bent manner and collectively define the cavity131f. The second film-portion131bis farther away from the color resist unit122than the first film-portion131a.

Optionally, the first film-portion131amay be partially attached to the surface of the color resist units122close to the light-exiting surface11, and partially attached to the peripheral side surface of the color resist unit122. On one hand, the first film-portion131acan carry the color resist unit122, and on the other hand, the charged particles1312accommodated in the transparent film1311can be disposed around the peripheral side of the color resist unit122, thereby realizing a comprehensive effect of privacy and anti-light leakage.

The second film-portion131bis connected to a peripheral edge of the first film-portion131aaway from the color resist unit122in a bent manner. Specifically, a peripheral edge of the second film-portion131bmay be, but is not limited to, connected to the peripheral edge of the first film-portion131ain a bent manner, so that the second film-portion131band the first film-portion131acooperatively define the cavity131f.

The second film-portion131bis farther away from the color resist unit122than the first film-portion131a, and the second film-portion131bmay be, but is not limited to, disposed in or partially disposed in the carrier plate121.

Optionally, the surface of the second film-portion131bmay be a flat surface (FIG.14), a curved surface, or the like, and the surface of the first film-portion131amay be formed by several sub-surfaces connected to one another in a bent manner, so as to be attached to the peripheral side surface of the color resist unit122.

Reference can be made toFIG.2andFIG.12, whereFIG.12is a schematic cross-sectional structural diagram of multiple privacy units and multiple color resist units in an embodiment of the present disclosure. The gap123is defined between the two adjacent color resist units122, and a transparent film1311in one of two adjacent privacy units131is located in part of the gap123. A transparent film1311in the other one of the two adjacent privacy units131is located in the other part of the gap123and abuts against the transparent film1311in said one of the two adjacent privacy units131.

Specifically, the multiple color resist units122may at least include a first color-resist-unit1221and a second color-resist-unit1222, and the multiple privacy films13may also at least include a first privacy-film132and a second privacy-film133. The first privacy-film132is disposed corresponding to the first color-resist-unit1221, that is, the first privacy-film132is disposed at one side of the first color-resist-unit1221close to the light-exiting surface11. The second privacy-film133is disposed corresponding to the second color-resist-unit1222, that is, the second privacy-film133is disposed at one side of the second color-resist-unit1222close to the light-exiting surface11. The first privacy-film132may have a first transparent film1313, and the first transparent film1313is disposed in part of the gap123. The second privacy-film133may have a second transparent film1314, and the second transparent film1314is disposed in the other part of the gap123. In addition, the first transparent film1313may partially abut against the second transparent film1314, so that multiple charged particles1312filled in the first privacy-film132and multiple charged particles1312filled in the second privacy-film133can block the gap123, and prevent light leakage and color mixing of light between the first color-resist-unit1221and the second color-resist-unit1222, thereby ensuring that the display panel10has excellent display taste.

It should be noted that the gap123may or may not be completely filled with the first privacy-film132and the second privacy-film133, which is not limited in the present disclosure.

Optionally, the surface of the first privacy-film132close to the first color-resist-unit1221and the surface of the second privacy-film133close to the second color-resist-units1222may be in the same horizontal plane or different horizontal planes. In other words, in other implementations of the present disclosure, a position of the first privacy-film132and a position of the second privacy-film133can also be adjusted according to the volume of the first color-resist-unit1221being different from the volume of the second color-resist-unit1222, as long as the first privacy-film132abuts against the second privacy-film133.

Reference can be made toFIG.2andFIG.13, whereFIG.13is a schematic structural diagram of a top view of a display panel in an embodiment of the present disclosure. The multiple charged particles1312are filled in the gap123, the gap123has a first orthographic projection123aon the light-exiting surface11, the multiple charged particles1312have a second orthographic projection131con the light-exiting surface11, and the second orthographic projection131cat least partially covers the first orthographic projection123a.

Specifically, when the privacy film13is in the first state or when the privacy film13is in the second state, the multiple charged particles1312are all filled in the gap123under the adsorption effect of the electrode1315. The first orthographic projection123ais an orthographic projection range of the gap123on the light-exiting surface11, the second orthographic projection131cis an orthographic projection range of the multiple charged particles1312on the light-exiting surface11, and the second orthographic projection131cmay, but is not limited to, cover or partially cover the first orthographic projection123a.

In an embodiment, the second orthographic projection131ccovers the first orthographic projection123a, so that the multiple charged particles1312can prevent the light leakage between the gap123. Therefore, the design of the black matrix in the traditional display panel can be replaced with the aid of the multiple charged particles1312, so that the display panel10has the privacy function, and the technological process of the display panel10can be simplified, thereby reducing the manufacturing cost of the display panel10.

Referring toFIG.2andFIG.13again, the color resist unit122have a third orthographic projection122aon the light-exiting surface11, and the third orthographic projection122aabuts against the second orthographic projection131c, but overlaps no second orthographic projection131c.

Specifically, the third orthographic projection122ais an orthographic projection range of the color resist unit122on the light-exiting surface11. The peripheral edge of the third orthographic projection122amay, but is not limited to, abut against or substantially abut against the second orthographic projection131c, and the third orthographic projection122aand the second orthographic projection131cdo not overlap with each other, so that the multiple charged particles1312have the privacy function and replace the black matrix, and do not affect a normal light-exiting effect of the color resist unit122, thereby ensuring the optical display effect of the display panel10.

It should be noted that in some implementations of the present disclosure, the display panel10may, but is not limited to, control the magnitude of the electrical signal loaded on the electrode1315or use other adjustment manners to control the movement track of the multiple charged particles1312and distribution positions of the multiple charged particles1312stagnated, so as not to affect the light-exiting effect of the surface of the color resist units122directly opposite to the light-exiting surface11. In addition, since the charged particles1312each have a bistable effect (a magnetic hysteresis effect) in the privacy unit131, when the charged particles1312keep at fixed positions in the display panel10, too much energy consumption will not be generated in the display panel10, and the display panel10can also balance the performance experience of energy conservation and low power consumption.

Reference can be made toFIG.15, whereFIG.15is a schematic cross-sectional structural diagram of a display panel taken along line A-A in a second state in yet another embodiment of the present disclosure. The privacy unit131further includes an electrode1315. The electrode1315is disposed at one side of the transparent film1311away from the cavity1311. When the electrode1315is loaded with an electrical signal, the electrode1315adsorbs the charged particles1312.

Specifically, the electrode1315is disposed at one side of the transparent film1311away from the cavity1311, and the electrode1315may be, but is not limited to, attached to the transparent film1311. A surface of the charged particle1312may, but is not limited to, carry positive (“+”) charges. When the electrode1315is loaded with the electrical signal, the electrode1315will attract the charged particles1312to positions of the transparent film1311close to the electrode1315, that is, the charged particles1312are adsorbed.

The electrode1315may be, but is not limited to, loaded with different electrical signals in different segments, so as to control the multiple charged particles1312to have different distribution states in the privacy unit131, so that the display panel10has different display viewing angles. Therefore, the display panel10can realize flexible privacy from multiple angles, and can also have the normal display state, that is, the display panel10has a full-viewing-angle experience.

Optionally, the electrode1315may also control the distribution states of the multiple charged particles1312by being loaded with electrical signals of different magnitudes or by other implementations.

It can be understood that in other implementations of the present disclosure, the electrode1315may also not be attached to the transparent film1311, as long as it is ensured that an electric field is generated to attract the charged particles1312and move the charged particles1312to designed positions.

It can be understood that in other implementations of the present disclosure, the charged particles1312may also carry other charges, as long as the charged particles are attracted by the electrode1315, which is not limited in the present disclosure.

The material of the electrode1315may be, but is not limited to, Indium Tin Oxides (ITO) or other conductive materials.

In an embodiment, the electrode1315is made of a transparent material, so that the electrode1315can attract and control the distribution states of the charged particles1312in the privacy unit131, and the normal display viewing angle of the display panel10is not affected.

Reference can be made toFIG.15andFIG.16, whereFIG.16is a schematic cross-sectional structural diagram of a display panel taken along line A-A in a first state in yet another of the present disclosure. The electrode1315includes a first electrode-portion131dand a second electrode-portion131e. The first electrode-portion131dis disposed at a peripheral side of a color resist unit122corresponding to the privacy unit131. The second electrode-portion131eexceeds the color resist unit122, and the second electrode-portion131eis closer to the first surface1211than the first electrode-portion131d. The multiple charged particles1312carry charges of a first polarity. When the first electrode-portion131dis loaded with a voltage signal of a second polarity and the second electrode-portion131eis loaded with a voltage signal of the first polarity, the multiple charged particles1312are adsorbed by the first electrode-portion131d, and the privacy film13is in the first state. When the first electrode-portion131dand the second electrode-portion131eeach are loaded with the voltage signal of the second polarity, the multiple charged particles1312are adsorbed by the first electrode-portion131dand the second electrode-portion131e, and the privacy film13is in the second state.

Specifically, the first electrode-portion131dis disposed at the peripheral side of the color resist unit122corresponding to the privacy unit131, and the first electrode-portion131dmay be, but is not limited to, disposed around the peripheral side of the color resist unit122. The second electrode-portion131eexceed the color resist unit122, that is, the second electrode-portion131eis closer to the first surface1211of the carrier plate121than the first electrode-portion131d.

Optionally, the first electrode-portion131dand the second electrode-portion131eeach may be, but are not limited to, formed by processes such as soldering, bonding, or integral molding, which is not limited in the present disclosure.

Optionally, the first electrode-portion131dmay be, but is not limited to, a portion disposed only on the peripheral side surface of the corresponding color resist unit122. Optionally, the first electrode-portion131dmay also be partially attached to the first film-portion131a, that is, the first electrode-portion131dmay, but is not limited to, include two portions that are connected to each other in a bent manner, where one portion of the first electrode-portion131dis attached to the first film-portion131aand is accommodated in the gap123between the two adjacent color resist units122, and the other portion of the first electrode-portion131dis attached to the second film-portion131band is accommodated in the gap123between the two adjacent color resist units122.

In an implementation of the present disclosure, the multiple charged particles1312may carry charges of the first polarity, and when the second electrode-portion131eis loaded with the voltage signal of the first polarity, the second electrode-portion131erepels the multiple charged particles1312due to the principle of like poles repulsion, so that the multiple charged particles1312do not stay at positions close to the second electrode-portion131e. At the same time, the first electrode-portion131dis loaded with the voltage signal of the second polarity, the first electrode-portion131dattracts the multiple charged particles1312, due to the principle of opposite poles attraction, so that the multiple charged particles1312are distributed at positions close to the first electrode-portion131d, that is, distributed at the peripheral side of the color resist unit122without exceeding the color resist unit122. Therefore, the privacy film13is in the first state, that is, the display panel10is in a shared state with a wide viewing angle.

When the second electrode-portion131eand the first electrode-portion131deach are loaded with the voltage signal of the second polarity, the first electrode-portion131dand the second electrode-portion131eeach attract the multiple charged particles1312due to the principle of opposite poles attraction, so that the multiple charged particles1312are distributed at positions close to the first electrode-portion131dand positions close to the second electrode-portion131e, that is, some of the multiple charged particles1312are partially distributed at the peripheral side of the color resist unit122and the rest of the multiple charged particles1312exceed the color resist unit122. Therefore, the privacy film13is in the second state, that is, the display panel10is in a privacy state with a narrow viewing angle.

It can be understood that in another implementation of the present disclosure, the multiple charged particles1312may carry charges of the first polarity. When the first electrode-portion131dis loaded with the voltage signal of the second polarity and the second electrode-portion131eis not loaded with a voltage signal, the multiple charged particles1312may also be distributed at positions close to the first electrode-portion131ddue to the attraction of the first electrode-portion131d, that is, distributed at the peripheral side of the color resist unit122without exceeding the color resist unit122, so that the privacy film13is in the first state, that is, the display panel10is in the shared state with the wide viewing angle. However, when the second electrode-portion131eand the first electrode-portion131deach are loaded with the voltage signal of the second polarity, the privacy film13is in the second state for the similar reason, that is, the display panel10is in the privacy state with the narrow view angle.

It can be understood that in yet another implementation of the present disclosure, the multiple charged particles1312may carry charges of the first polarity, and the first electrode-portion131dand the second electrode-portion131eeach are loaded with the voltage signal of the second polarity. When the first electrode-portion131dand the second electrode-portion131eeach are loaded with a first voltage signal, the privacy film13is in the first state. When the first electrode-portion131dand the second electrode-portion131eeach are loaded with a second voltage signal, the privacy film13is in the second state. A signal value of the second voltage signal is greater than a signal value of the first voltage signal. In other words, the privacy film13is controlled to be in different states by controlling the magnitude of the voltage signal loaded on the electrode1315.

It should be noted that the electrode1315may further include multiple electrode portions, so that multistage control can be performed by the electrode1315, and the multiple charged particles1312can be controlled to have multiple distribution states by different signals loaded on the electrode portions of different stages.

It can be understood that the electrode1315may also be loaded with multiple voltage signals of different magnitudes to control the multiple charged particles1312to have multiple distribution states.

For the display panel10provided in this implementation of the present disclosure, the privacy film13can be flexibly switched between the first state, the second state, or other states by multiple control manners, so that the display panel10can realize the privacy state at multiple viewing angles, and can have the normal display effect. Therefore, the display panel10can meet multi-scenario user experience and intelligence requirements of the user.

Referring toFIG.2again, the carrier plate121further defines multiple recesses1213corresponding to the multiple privacy units131, different recesses1213correspond to different privacy units131, and at least part of the privacy unit131is accommodated in the corresponding recess1213.

The number of recesses1213may be, but is not limited to, two, three, four, or other number, etc. The number of the recesses1213may be, but is not limited to, equal to the number of the anti-peeping units131.

Further, the recess1213is defined at one side of the carrier plate121close to the second surface1212, and the recess1213may, but is not limited to, directly face the privacy unit131. Furthermore, different recesses1213directly face different privacy units131respectively.

The privacy unit131may be, but is not limited to, accommodated in the recess1213, or partially accommodated in the recess1213, so that compared to traditional designs of the privacy assembly on the display panel alone, due to the privacy unit131provided in this implementation, the display panel10has the privacy function, and the thickness of the display panel10is also increased as small as possible or is not additionally increased, so that the display panel10can meet the design requirements of lightness and thinness.

Further, in an implementation of the present disclosure, the manufacturing process of the recess1213, the privacy unit131, and the color resist unit122may include the following. step one, manufacture a privacy unit; step two, provide a carrier blank, and define a recess on the carrier blank to obtain a carrier plate; step three, dispose the privacy unit on the carrier plate at a position corresponding to the recess; and step four, coat a color resist unit at one side of the privacy unit away from the carrier plate.

In another implementation of the present disclosure, the manufacturing process of the recess1213, the privacy unit131, and the color resist unit122may include the following. Step one, provide a carrier blank, and define a recess on the carrier blank to obtain a carrier plate; step two, manufacture a privacy unit in the recess; and step three, coat a color resist unit at one side of the privacy unit away from the carrier plate.

In yet another implementation of the present disclosure, the manufacturing process of the recess1213, the privacy unit131, and the color resist unit122may include the following. Step one, provide a flexible base; step two, coat a color resist unit on the flexible base; step three, manufacture a privacy unit on a surface of the color resist unit; step four, manufacture a carrier plate on a surface of the privacy unit and a surface of the flexible base; and step five, peel off the flexible base.

It can be understood that the display panel may also be manufactured by other technological processes, and the technological manufacturing process of the display panel should not be a limitation to the display panel in implementations of the present disclosure.

Referring toFIG.15again, the display panel10further includes a signal line14. The signal line14is disposed on the carrier plate121, is electrically connected to the electrode1315, and is configured to load the electrical signal to the electrode1315.

Optionally, the signal line14may be, but is not limited to, partially disposed in the carrier plate121.

Optionally, one end of the signal line14may be electrically connected to the electrode1315, and the other end of the signal line14may be, but is not limited to, electrically connected to an Integrated Circuit (IC) chip of the display panel10. The IC signal can transmit different control signals to the signal line14, so that the signal line14load different electrical signals to the electrode1315, thereby controlling different states of the privacy film13and realizing the full-viewing-angle display effect of the display panel10. In other words, when the privacy film13is in different states, the light emitted from the light-exiting surface11of the display panel10has different view angle ranges.

It can be understood that in an implementation of the present disclosure, a user can independently choose a viewing angle range of the display panel10based on the requirements, and a privacy degree of the display panel10can also be adjusted according to different distribution states of the multiple charged particles1312, so that the display panel10has a wider application range, and the user can have more choices, thereby effectively improving the user experience.

Referring toFIG.1,FIG.2, andFIG.3again, the display device1includes a housing20and the display panel10. The housing20is configured to accommodate the display panel10.

The display device1may be, but is not limited to, a device having a display function, which is for a smart phone, a portable phone, a navigation device, a Television (TV), an in-vehicle head unit, a laptop computer, a tablet computer, a Portable Multimedia Player (PMP), a Personal Digital Assistant (PDA), and the like. It can be understood that an application scenario of the display device1shall not be a limitation to the display device1provided in this implementation.

The material of the housing20may be, but is not limited to, a metal, an alloy, a plastic, or another composite material. It can be understood that the material of the housing20shall not be a limitation to the display device1provided in this implementation. The housing20can be configured to accommodate and carry the display panel10.

The display panel10may further include an array substrate15, and the array substrate15may be, but is not limited to, opposite to the color film substrate12. When the display panel10is a LC display panel10, the array substrate15may be provided with a metal electrode1315for driving LC molecules. It can be understood that metal electrodes1315for driving liquid crystal molecules in a traditional display panel are all disposed on the array substrate15, and only the signal line14and the electrodes1315for controlling the privacy units131are designed on the color film substrate12, so that the display panel10has a wider application range. It can be understood that the privacy unit131may also be for display panels10with different types of functions, such as an OLED display panel10and the like, which is not limited in the present disclosure.

For the display device1provided in this implementation of the present disclosure, the display panel10can have a full-viewing-angle display state, that is, the display panel10can flexibly switch between the privacy state and the normal display state. In addition, the multiple charged particles1312are at least partially disposed in the gap123between the two color resist units122, so that the design of the black matrix in the traditional display panel can be replaced with the aid of the multiple charged particles1312, thereby simplifying the technological manufacturing process of the display panel10, and reducing the manufacturing cost of the display panel10and the display device1. Furthermore, when the display device1implements the privacy function, there are multiple viewing angles to be chosen, thereby improving the user experience of the display device1.
