The present disclosure proposes a detection support100.

Referring toFIGS. 1 to 4, in the embodiment of the present disclosure, the detection support100is configured to support the display panel200, the display panel200includes opposing first and second surfaces, the direction from the first surface to the second surface is a first direction, the detection support100includes at least one support assembly10, and the support assembly10includes:

a base1, sequentially defining a first accommodation groove11and a second accommodation groove12at interval along the first direction;

a first stop block2, detachably connecting the base1and being accommodated in the first accommodation groove11; and

a second stop block3, detachably connecting the base1and accommodated in the second accommodation groove12;

When the display panel200is disposed on the detection support100, the base1abuts against one lateral side of the display panel200, and the first stop block2and the second stop block3abut against the first surface and the second surface, respectively.

In this embodiment, the detection support100is defined to support the display panel200in an upright state, thereby facilitating the testing of the optical performance of the display panel200to ensure the qualified rate of the display panel200. The display panel200is a display device that is common in our daily life, and includes a first surface and a second surface which are opposite to each other, and four lateral sides. When the size of the real panel200is small, the amount of support assemblies10may be defined to one. Of course, in order to provide more stable support, it is generally to use two support assemblies10together. The base1is in a shape of a long plate with a certain thickness, and its material may be metal and of a large mass, so that it may play a very good stabilizing role. Of course, the material of the base1is not limited to metal, such as bakelite, plastic or other materials. The base1is integrally formed to effectively improve its structural strength. The connection of the first stop block2, the second stop block3and the base1may respectively be the one selected from a group consisting of a threaded connection, a snap connection or other detachable connection.

The base opening1is defined with a first accommodation groove11and a second accommodation groove12, and the distance between the first accommodation groove11and the second accommodation groove12equals the thickness of a display device200of a size in prior art, so that it is convenient to clamp common display devices. The depth of the first accommodation groove11matches the thickness of the first stop block2, the depth of the second accommodation groove12matches the thickness of the second stop block3, and the width of the first accommodation groove11is slightly larger than the width of the first stop block2, and the width of the second accommodation groove12is slightly larger than the width of the second stop block3, thus making the first stop block2and the second stop block3more convenient in the transition between accommodating state and supporting state.

The first stop block2and the second stop block3are both defined with one and have a simple structure, and they respectively abut against the opposite first surface and the second surface of the display panel200when they are in the working state. Of course, the base1may also be defined wider, so as to define a plurality of the first and the second accommodation grooves11and12in parallel. One of the first stop block2and second stop blocks3may be defined with one, and the other one may be defined plural, so as to making the clamping more stable. Of course, it is also possible that both the first stop block2and the second stop block3are defined with a plurality, and the amount is not limited here.

When the display panel200is disposed on the detection support100, one of the first stop block2and the second stop block3may abut against the screen of the display panel200and the other may abut against the back plate of the display panel200. In the following embodiments, the first surface is defined as a screen, the second surface is defined as a back plate surface, the first stop block2abuts against the screen of the display panel200, and the second stop block3abuts against the back plate of the display panel200. Of course, it is also possible that the first stop block2abuts against the back plate of the display panel200and the second stop block3abuts against the screen of the display panel200. The surfaces of the second stop block3and the first stop block2facing the display panel200may fully or partially abut against the surface of the display panel200. In this embodiment, the first stop block2and the second stop block3are defined in parallel so that both fully abut against the surface of the display panel200, thereby further increasing the stability of the clamping.

According to the technical scheme of the disclosure, the first stop block2and the second stop block3are defined to cooperate with the base1to form a clamping structure, which is simple in structure and does not require a complicated connection relationship. The clamping structure may clamp two opposite surfaces and one lateral side surface of the display panel200, i.e., the base1abuts against one lateral side of the display panel200, the first stop block2abuts against the first surface and the second stop block3abuts against the second surface. The structure reduces the height of the support display panel200and increases the contact area between the detection support00and the display panel200, thereby providing stable support without falling and damaging the display panel200. And, the first stop block2and the second stop block3are detachably connected with the base1and may be accommodated in the first accommodation groove11and the second accommodation groove12, respectively. When the detection support100is not used or transferred, the first stop block2and the second stop block3may be accommodated in parallel with the base1, and no disassembly is required, which is simple and convenient, thereby saving space, and facilitating storage and carrying.

Please referring toFIGS. 1 and 2, in some embodiments of the present disclosure, the first stop block2and the second stop block3are respectively rotatably connected with the base1.

In the embodiment, in order to facilitate the transition of the first stop block2and the second stop block3of the support assembly10between accommodating state and supporting state, the first stop block2is rotatably connected with the base1, and the second stop block3is also rotatably connected with the base1. Therefore, when not in use, the first stop block2and the second stop block3may be rotated to be respectively accommodated in the first accommodation groove11and the second accommodation groove12, which is simple, convenient, and time and labor saving. In the use state, the first stop block2and the second stop block3are rotated to the abutment position again, and both are fixed to stabilize in the abutment position, thereby achieving stable support.

Referring toFIGS. 5ato7, in some embodiments of the present disclosure, two first mounting holes13are defined through the two side walls of the first accommodation groove11, two second mounting holes14are defined through the two side walls of the second accommodation groove12, and the first stop block2and the second stop block3are respectively defined with a first connecting hole21and a second connecting hole31.

A connector4penetrates the first mounting hole13and the first connecting hole21, and cooperates with the fastener5so that the first stop block2is screwed to the base1, and another connector4penetrates the second mounting hole14and the second connecting hole31and cooperates with the fastener5so that the second stop block3is screwed to the base1.

In this embodiment, the connector4is inserted into the first mounting hole13and the first connecting hole21. The connector4is a bolt, the fastener5is a nut, the first connecting hole21is in interference fit with the connector4, and the connector4is loosely fit with the first mounting hole13, thus facilitating the connector4to rotate in the first mounting hole13while driving the first stop block2to rotate. When the fastener is screwed into the connector4, the first stop block2is in a stable state. The arrangement of the structure not only may realize the rotational connection between the first stop block2and the base1, but also may realize the stable fixation of the first stop block2, which is simple, convenient, and saves materials and processing costs. Similarly, the second stop block3is also penetrated into the second connecting hole31and the second mounting hole14through the connector4, so that it may be rotationally connected with the base1or may be stably fixed when it is rotated to the right place. Of course, the rotational connection may also be other connection methods such as shaft hole rotation, and provide a supporting and fixing structure.

Please referring toFIGS. 2, 5aand5b, in some embodiments of the present disclosure, the distance between the first stop block2and the second stop block3in the first direction is adjustable.

In this embodiment, the first stop block2and the second stop block3may be defined at right angles or acute angles to the base1according to actual requirements, so that the display panel200is defined perpendicular to the base1or obliquely to the base1, facilitating measurement of optical color gamut, uniformity, transmittance, etc. And, the distance between the first stop block2and the second stop block3along the first direction may be adjusted so that the detection support100may be defined to clamp display panels200of different thicknesses, thereby making the detection support be used more widely, and be more practicable.

In some embodiments of the present disclosure, the second mounting hole14is a strip-shaped hole or a waist-shaped hole extending in a first direction, and the connector4drives the second stop block3to move in the second mounting hole14.

In this embodiment, the second stop block3is slidably disposed relative to the base1, and the first stop block2does not move relative to the base1in the first direction, so that the distance between the first stop block2and the second stop block3may be adjusted to clamp display panels200of different thicknesses only by adjusting the position of the second stop block3, which is simple in structure, convenient to operate, and improves detection efficiency. The second mounting hole14is a strip-shaped hole or a waist-shaped hole extending along the first direction, so that the connector4that penetrating through the second mounting hole14may slide along the first direction, thereby driving the second stop block3to slide along the first direction, thereby increasing the distance between the first stop block2and the second stop block3along the first direction and achieving the purpose of clamping display panels200of different thicknesses. The size of the second mounting hole14matches the size of the connector4so as to facilitate sliding without loosening the connector4too much. The connector4slides in the second mounting hole14and is fixed in a proper position, thereby forming a certain clamping distance to clamp a certain thickness of the display panel200. Of course, it is also possible to define the first mounting hole14as a strip-shaped hole or a waist-shaped hole extending in the first direction so as to move the first stop block3to adjust the distance between the first stop block2and the second stop block3in the first direction. It is also possible to provide that both the first stop block2and the second stop block3are slidably defined with the base1, so that the distance adjustment between the first stop block2and the second stop block3is more selective.

Please refer toFIG. 2, in some embodiments of the present disclosure, when the display panel200is disposed on the detection support100, the first stop block2and the second stop block3are defined perpendicular to the base1.

In this embodiment, the first stop block2and the second stop block3are both perpendicular to the base1, so that the display panel200may be completely upright in the horizontal plane, thereby allowing the weight of the display panel200to directly press on the base1, reducing the bending pressure on the first stop block2and the second stop block3, and making the use of the detection support100more durable. The efficiency of optical testing may also be improved.

In some embodiments of the present disclosure, the groove bottoms of the first accommodation groove11and the second accommodation groove and12are respectively defined with a first receiving hole16and a second receiving hole17. When the display panel200is disposed on the detection support100, the end portions of the first and second stop blocks2and3are respectively located in the first receiving hole16and the second receiving hole17.

In this embodiment, the groove bottom of the first accommodation groove11is defined with a first receiving hole16, and the groove bottom of the second accommodation groove12is defined with a second receiving hole17. The shapes of the first receiving hole16and the second receiving hole17may be square or circular or other shapes. The length of the first receiving hole16is approximately the same as the diameter of the first mounting hole13, and the length of the second receiving hole17is the same as the length of the second mounting hole14, so that the end portion of the second stop block3may also be placed in an accommodating state when adjusting the space conveniently. The definition of this structure may reduce the depths of the first accommodation groove11and the second accommodation groove12, and keep the depths consistent with the thickness of the first stop block2and the second stop block3, so that the mounting positions of the first stop block2and the second stop block3are more closely fitted to the base1and the support structure is more stable.

Please referring toFIGS. 2, 6 and 7, in some embodiments of the present disclosure, the first stop block2and the second stop block3are both long rods, and the length of the first stop block2is smaller than the length of the second stop block3.

In this embodiment, in order to further improve the clamping stability, the first stop block2is in the shape of a long rod, and since it clamps on the screen surface of the display panel200, it is not appropriate to define its height, width, and thickness too large in case that the first stop block2blocks the screen. Specifically, the first surface is a display screen surface and the second surface is a back panel surface. The height of the first stop block2is approximately equal to half of the height of the display panel200, which is not limited here. The thickness is less than or equal to 5 mm and the width is less than or equal to 15 mm. In order to further reduce the influence on the screen test, the material of the first stop block2is defined as a light transmissive material, so that when carrying out the optical test, the light rays may not be blocked from entering the screen of the display screen, thereby not only providing stable clamping, but also not affecting the normal test. The light transmissive material may be glass, light-transmitting plastic, resin, etc.

According to the principle of reflection and refraction of light rays, when the incident surface and the exit surface of light rays are parallel, the light path may be kept unchanged, thus reducing the attenuation of light to a greater extent. Therefore, in order to further reduce the influence of the first stop block2and facilitate the formation of the first mounting hole21, the cross-sectional shape of the first stop block2is rectangular, and the two opposite surfaces of the rectangle are both parallel surfaces. When the cross-sectional shape is semicircular, incident light is still emitted as parallel light after reflection and refraction, so the shape may effectively reduce light attenuation and improve the accuracy of optical testing of the display panel200.

The material of the second stop block3may be metal, plastic or wood, etc., and has good bending and compression resistance. The second stop block3abuts against the back plate surface of the display panel200and does not affect the optical test. The height of the second stop block3is larger than the height of the first stop block2, which may be defined according to the height of the display panel200, and the width may also be defined to a larger size, but the matching relationship with the base1is guaranteed not to be affected so as to provide a more stable support. And, the back plate surface of the display panel200commonly has a certain degree of arc, so the joint between the two sides of the second stop block3may be chamfered to better match with the back plate, thereby improving the clamping stability without scratching the back plate.

Please referring toFIGS. 3 and 4, in some embodiments of the present disclosure, the support assembly10is defined with two, the two support assemblies10are spaced apart, the first stop blocks2of the two support assemblies10abut against the first surface together, and the second stop blocks3of the two support assemblies10abut against the second surface together.

In this embodiment, in order to further improve the clamping stability, two support assemblies10are provided, and the two support assemblies10are parallelly defined at intervals so as to provide uniform and stable support for the display panel200and facilitate the testing of the display panel200. And it is not necessary to define the same size as the display panel200, thereby further reducing the size of the detection support100and making it more convenient to carry, use and store.

And, according to the size of the display panel200, the distance between the two support assemblies10is defined as adjustable in the direction perpendicular to the first direction, so that the detection support is adapted to the display panel200with various screen size specifications, meeting the clamping requirements. Of course, it is also possible to provide three or more support assemblies10to improve support stability while meeting the support requirements of a larger display panel200.

The above is only an optional embodiment of the present disclosure and is not intended to limit the patent scope of the present disclosure. Any equivalent structural change made by using the contents of the specification and drawings of the present disclosure or directly/indirectly applied in other related technical fields is included in the patent scope of the present disclosure under the inventive concept of the present disclosure.
