[0058] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusion and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first" and "second", etc. are used merely as labels and are not intended to limit the quantity of their objects.

[0059] The present disclosure first provides an optical measurement stand for a display device. The optical measurement stand can be rotated to change the angle between the display device and the optical measurement instrument, and thus the optical characteristics of the display device at various angles can be measured. At the same time, the optical measurement stand has a simple structure and is easy to operate.

[0060] In one embodiment of the present disclosure, Figures 1 to 6 As shown, the optical measurement stand of the display device may include: a base 1, a first bracket 2 and a second bracket 3. Among them, one end of the first bracket 2 can be connected to the base 1, and the other end can extend in a direction away from the base 1. The second bracket 3 can be spaced apart from the first bracket 2 in the first direction X, and one end of the second bracket 3 can be connected to the base 1, and the other end can extend in a direction away from the base 1. The rotating bearing platform 4 can be arranged between the first bracket 2 and the second bracket 3, and the rotating bearing platform 4 can be rotatably connected to the first bracket 2 and the second bracket 3. The rotating bearing platform 4 can be provided with a positioning portion 41, and the positioning portion 41 can locate the center point of the display device.

[0061] The optical measurement stand of the display device provided by the present disclosure may include: a base 1, a first bracket 2, a second bracket 3 and a rotating bearing platform 4. When measuring the optical characteristics of the display device, the display device can be placed on the rotating bearing platform 4. In addition, the rotating bearing platform 4 is provided with a positioning portion 41, which can position the center point of the display device, thereby ensuring the accuracy of the placement position of the display device on the rotating bearing platform 4, so as to ensure the accuracy of the measurement result.

[0062] At the same time, the rotating bearing platform 4 can be arranged between the first bracket 2 and the second bracket 3, and can be rotatably connected with the first bracket 2 and the second bracket 3. Therefore, when it is necessary to measure the optical characteristics of the display device, the rotating bearing platform 4 can be rotated to change the angle between the display device and the optical measuring instrument, so that the optical characteristics of the display device at various angles can be measured conveniently and quickly. Therefore, the optical measurement stand for the display device provided by the present disclosure is more convenient to operate than the prior art, thereby improving the efficiency of measuring the optical characteristics of the display device.

[0063] Furthermore, since the optical measurement stand of the display device is only provided with the base 1, the first bracket 2, the second bracket 3 and the rotating support platform 4, the optical measurement stand of the display device provided by the present disclosure has a simpler structure than the prior art, which can reduce the cost of manufacturing the optical measurement stand of the display device, thereby effectively reducing the cost of measuring the optical characteristics of the display device.

[0064] In one embodiment, the optical characteristics of the display device may include but are not limited to the half-height width of the display device. Here, the half-height width of the display device refers to the observation angle corresponding to the half-height width of the display device when the brightness of the display device is half of the reference brightness when the display device is viewed at a normal viewing angle at a specific setting angle of the display device.

[0065] Therefore, when using an optical measuring instrument to measure the half-height width of a display device, the brightness measured when the optical measuring instrument and the display device are facing each other can be used as the reference brightness, and the angle between the optical measuring instrument and the display device can be changed. When the brightness measured by the optical measuring instrument is equal to the reference brightness, the angle between the optical measuring instrument and the display device is the measured half-height width of the display device.

[0066] It should be noted that the optical measurement stand of the display device can not only measure the half-height width of the display device, but also measure the optical properties of the display device such as brightness at various angles. It can be selected and set according to actual needs, which is within the protection scope of the present disclosure.

[0067] In one embodiment, the optical measuring instrument mentioned above may be an optical measuring lens, but is not limited thereto. The type of the optical measuring instrument may also be selected and set according to actual measurement needs.

[0068] In one embodiment of the present disclosure, Figures 1 to 3As shown, the rotating bearing platform 4 may include: a bearing platform 42 and a tray 43. The positioning portion 41 may be disposed on the bearing platform 42. When the optical characteristics of the display device need to be measured, the display device may be placed on the bearing platform 42.

[0069] The tray 43 can be rotatably connected to the first bracket 2 and the second bracket 3, and the bearing platform 42 can be connected to the tray 43. The tray 43 may include a bottom 431 and a flange 432. Among them, the flange 432 can be connected to the bottom 431 and can extend in a direction away from the bottom 431, the bearing platform 42 can be placed on the bottom 431, and the flange 432 can surround the bearing platform 42. Such a setting can facilitate the disassembly and replacement of the bearing platform 42. At the same time, such a setting can also facilitate the rotation of the bearing platform 42 on the horizontal plane, which can also change the setting angle of the display device on the horizontal plane, so that the optical characteristics of the display device at different setting angles can be measured. In addition, such a setting can also use the flange 432 to limit and stop the bearing platform 42, so as to ensure the position accuracy of the bearing platform 42 installed on the tray 43, and reduce the probability of the bearing platform 42 falling off the tray 43.

[0070] It should be noted that, in this embodiment, the above-mentioned carrying platform 42 can be connected to the tray 43, which can be understood as the carrying platform 42 can be connected to the bottom 431, or the carrying platform 42 can be connected to the flange 432, or the carrying platform 42 can be connected to both the bottom 431 and the flange 432.

[0071] In one embodiment, Figures 1 to 3 As shown, the bottom 431 may include: a main body 4311 and a connecting block 4312. The main body 4311 may be an annular structure, and the main body 4311 may be connected to the flange 432. The present disclosure can reduce the weight of the main body 4311 by setting the main body 4311 as an annular structure, so that the operator can rotate the main body 4311 more easily, thereby further improving the ease of operation of the optical measurement stand of the display device. At the same time, by setting the main body 4311 as an annular structure, the material for making the main body 4311 can be saved, thereby reducing the cost of making the main body 4311, thereby further reducing the cost of measuring the optical characteristics of the display device.

[0072] The connecting block 4312 may be connected to the inner circumference of the main body 4311, and the connecting block 4312 may extend toward the center of the main body 4311. The carrying platform 42 may be connected to the connecting block 4312. In this way, the connecting block 4312 may be used to provide a stable connection position for the carrying platform 42, thereby ensuring the stability of the connection between the carrying platform 42 and the tray 43.

[0073] In one embodiment, the side of the carrying platform 42 close to the base 1 can be connected to the side of the connecting block 4312 away from the base 1. In this way, the connecting block 4312 can provide a certain support force to the carrying platform 42 while ensuring the stability of the connection between the carrying platform 42 and the tray 43.

[0074] In one embodiment, a plurality of connection blocks 4312 may be provided, and the plurality of connection blocks 4312 may be spaced apart along the inner circumference of the body portion 4311. Such a configuration may further improve the connection stability between the carrying platform 42 and the tray 43, and may further improve the supporting capacity of the connection block 4312 for the carrying platform 42.

[0075] Multiple connecting blocks 4312 can be evenly spaced along the inner circumference of the main body 4311, so that when the supporting platform 42 is connected to the multiple connecting blocks 4312, it can be ensured that the load borne by each connecting block 4312 is the same, avoiding the problem of individual connecting blocks 4312 breaking due to excessive load.

[0076] In one embodiment, the first connection part may be provided on the side of the carrying platform 42 close to the base 1, and the second connection part 4313 may be provided on the side of the connecting block 4312 away from the base 1. The carrying platform 42 and the connecting block 4312 may be connected via the first connection part and the second connection part 4313.

[0077] In this embodiment, the first connecting portion may be a first magnetic portion, and the second connecting portion 4313 may be a second magnetic portion. The first magnetic portion and the second magnetic portion have opposite magnetic properties, so that the mutual attraction between the first magnetic portion and the second magnetic portion can be used to connect the carrying platform 42 and the connecting block 4312. This arrangement can facilitate the installation and removal of the carrying platform 42.

[0078] In one embodiment, the material of the carrying platform 42 may be a metal material, such as aluminum alloy, iron, etc. At this time, the first connecting portion may be a side of the carrying platform 42 close to the base 1, and the second connecting portion 4313 may be a magnet.

[0079] In another embodiment of the present disclosure, the first connection part may not be the first magnetic part, and the second connection part 4313 may not be the second magnetic part. For example, the first connection part may be a connection hole, such as a threaded hole, etc.; the second connection part 4313 may be a connector, such as a screw, etc. The connection hole and the connector may be used to connect the support platform 42 and the connection block 4312, but it is not limited thereto. The support platform 42 and the connection block 4312 may also be connected by other connection methods, that is, the first connection part and the second connection part 4313 may also be other forms of connection parts, which may be selected and set according to actual needs, all of which are within the protection scope of the present disclosure.

[0080] In one embodiment of the present disclosure, Figures 1 to 3 As shown, the flange portion 432 may be provided with a slot 4321 extending along the second direction Y. The outer peripheral surface of the carrying platform 42 may be provided with a block 421, and the block 421 may be engaged in the slot 4321. The second direction Y may be the direction from the carrying platform 42 to the tray 43. With such a configuration, the slot 4321 may be used to further limit the carrying platform 42, ensuring that the setting angle of the carrying platform 42 in the horizontal direction is the setting angle required for measurement, and also ensuring that the setting angle of the display device in the horizontal direction is the setting angle required for measurement.

[0081] In one embodiment, the flange portion 432 may be a circular ring structure, and the flange portion 432 may be provided with a plurality of slots 4321, and the plurality of slots 4321 may be arranged at intervals along the circumference of the flange portion 432. In this way, a plurality of setting angles in the horizontal direction may be provided for the carrying platform 42. The block 421 may be inserted into the required slot 4321 according to the measurement requirements.

[0082] For example, the flange portion 432 may be provided with five slots 4321, and the angles between the lines connecting the center point of the display device and the center points of the five slots 4321 and the first direction X may be 0°, 45°, 90°, 135° and 180°, respectively. With such a configuration, a plurality of fixed setting angles may be provided to the carrying platform 42, so that the operator can directly select the setting angle, thereby further improving the convenience of operation of the optical measurement stand of the display device. However, the number of the slots 4321 provided in the flange portion 432 may not be five, and may be selected and set according to actual needs, which is within the protection scope of the present disclosure.

[0083] In one embodiment, the shape of the main body 4311 may also be a circular ring to match the flange 432. However, the shape of the main body 4311 may also be a polygon, etc., and may be set according to actual needs.

[0084] In one embodiment of the present disclosure, Figure 1 and Figure 3 As shown, the carrying platform 42 may include: a main body 422, a storage platform 423 and a handle 424. Among them, the block 421 may be arranged on the outer peripheral surface of the main body 422, and a receiving groove 4221 may be arranged on the side of the main body 422 away from the tray 43. The storage platform 423 may be arranged in the receiving groove 4221, and the positioning portion 41 may be arranged on the storage platform 423, and the display device may be placed on the storage platform 423. In this way, the side wall of the receiving groove 4221 may be used to limit and stop the display device, so as to reduce the probability of the display device falling off from the storage platform 423.

[0085] The handle 424 may be disposed on a side of the main body 422 facing away from the tray 43 to assist in the installation and removal of the carrying platform 42 .

[0086] In one embodiment, the positioning portion 41 may be a positioning scale 411, and the positioning scale 411 may include two mutually perpendicular and intersecting positioning scale lines 4111, and the intersection point between the two positioning scale lines 4111 is the position where the center point of the display device is located. Such a setting can further improve the positioning accuracy of the display device.

[0087] In one embodiment, the carrying platform 42 may also be provided with a wiring through hole 44 , through which a connection line of the display device may electrically connect the display device to an external power source.

[0088] In one embodiment of the present disclosure, Figure 1 and Figure 4 As shown, the first bracket 2 may include: a first bracket portion 21, a first rotating portion 22, an angle scale portion 23 and an indication portion 24.

Such a configuration allows the operator to directly read the angle value of the rotation of the rotating bearing platform 4 through the indication portion 24 and the angle scale portion 23 without the need for other angle measurement tools.

[0089] In one embodiment, the first rotating portion 22 may be connected to the main body 4311 of the rotating support platform 4 so that the main body 4311 and the first rotating portion 22 may rotate synchronously, thereby driving the support platform 42 and the first rotating portion 22 to rotate synchronously.

[0090] In one embodiment, the first bracket 2 may further include a first connecting structure 27 , the main body 4311 may be provided with a third connecting portion 4314 , and the first connecting structure 27 is connected to the third connecting portion 4314 and the first rotating portion 22 to connect the main body 4311 with the first rotating portion 22 .

[0093] The indicator portion 24 and the first connection structure 27 may be sleeved on the outer circumferential surface of the first connection shaft, so that the indicator portion 24 and the first connection structure 27 are connected to the first connection shaft.

[0094] In one embodiment, the axis of the first rotating portion 22 may be at the same height as the side of the platform 423 facing away from the base 1 in the second direction Y. This arrangement ensures that the center point of the display device always remains at the same height during the rotation process, thereby further ensuring the accuracy of the measurement structure.

[0095] In one embodiment, the angle scale 23 can be arranged on a side of the first bracket 21 away from the rotating platform 4, and the indicator 24 can be arranged on a side of the first bracket 21 away from the rotating platform 4.

In this way, the operator can rotate the adjustment knob 261 to make the second transmission part 262 rotate synchronously with the adjustment knob 261. At this time, the second transmission part 262 can drive the first transmission part 25 to rotate so that the first rotating part 22 rotates. Therefore, through the above-mentioned arrangement, the present disclosure can use the adjustment knob 261 to control the rotation of the carrying platform 42.

[0098] In one embodiment, the first transmission part 25 and the second transmission part 262 can be arranged on a side of the first bracket part 21 close to the rotating support platform, and the adjusting knob 261 can be arranged on a side of the first bracket part 21 away from the rotating support platform. Such an arrangement can provide an operator with a larger operating space when turning the adjusting knob 261, thereby facilitating the operator to turn the adjusting knob 261.

[0099] In one embodiment, the first transmission part 25 and the second transmission part 262 may both be gears, and the first transmission part 25 and the second transmission part 262 may mesh with each other, so that the second transmission part 262 can drive the first transmission part 25 to rotate. In addition, when the first transmission part 25 and the second transmission part 262 are both gears, the transmission efficiency between the first transmission part 25 and the second transmission part 262 can be guaranteed.

[0100] However, the present invention is not limited thereto, and the first transmission part 25 and the second transmission part 262 may not be gears. For example, the first transmission part 25 and the second transmission part 262 may both be rollers, and the outer circumference of the first transmission part 25 and the outer circumference of the second transmission part 262 may fit each other, so that the second transmission part 262 can drive the first transmission part 25 to rotate. The present disclosure does not limit the specific structures of the first transmission part 25 and the second transmission part 262, and they may be configured according to actual needs.

[0101] In one embodiment of the present disclosure, Figure 1 , Figure 4 and Figure 5As shown, the optical measurement stand of the display device may further include: a locking assembly 5.

When the locking member 52 is in the first state, the locking member 52 abuts against the second transmission portion 262 to lock the second transmission portion 262; when the locking member 52 is in the second state, the locking member 52 releases the second transmission portion 262.

[0102] Thus, when the rotating platform 42 rotates to a desired angle, the locking member 52 can be in the first state, thereby preventing the second transmission part 262 from rotating, and thus ensuring that the rotating platform 42 can always be kept at this angle. When the rotating platform 42 needs to change the rotation angle, the locking member 52 can be in the second state, thereby enabling the second rotating part 32 to continue rotating, so as to continue adjusting the angle of the rotating platform 42.

[0103] In one embodiment, the locking member 52 may include: a locking link structure 521, a friction member 522, and an adjustment structure 523. The friction member 522 may be connected to the locking link structure 521 through the adjustment structure 523. The operator may operate the locking link structure 521 to move the friction member 522 toward or away from the second transmission part 262, and may adjust the fit tightness between the friction member 522 and the second transmission part 262 through the adjustment structure 523.

[0104] In one embodiment, the adjustment structure 523 may include a lead screw 5231 and a nut 5232. The lead screw 5231 may pass through the locking link structure 521, the friction member 522 may be connected to one end of the lead screw 5231 close to the second transmission part 262, the nut 5232 may be threadedly connected to the lead screw 5231, and the nut 5232 may be located on a side of the locking link structure 521 away from the friction member 522, so that the nut 5232 may be used to adjust the fit tightness between the friction member 522 and the second transmission part 262.

[0105] In one embodiment of the present disclosure, Figure 1 As shown, the second bracket 3 may include: a second bracket portion 31 and a second rotating portion 32.

[0106] In one embodiment, the second rotating portion 32 may be connected to the main body 4311 of the rotating support platform 4 so that the main body 4311 and the second rotating portion 32 may rotate synchronously, thereby driving the support platform 42 and the second rotating portion 32 to rotate synchronously.

[0107] In one embodiment, the second bracket 3 may further include a second connecting structure 33 , the main body 4311 may be provided with a fourth connecting portion 4315 , and the second connecting structure 33 is connected to the fourth connecting portion 4315 and the second rotating portion 32 to connect the main body 4311 with the second rotating portion 32 .

[0108] In this embodiment, the second connection structure 33 and the fourth connection part 4315 can be connected by a connection piece, that is, the second connection structure 33 and the fourth connection part 4315 can be provided with connection holes, and the connection piece can connect the second connection structure 33 and the fourth connection part 4315 through the connection holes.

[0109] In one embodiment, the second bracket 3 may be provided with a second bearing, and the second bearing may be installed in the second bracket portion 31. The second rotating portion 32 may be a second connecting shaft, and the second connecting shaft may pass through the second bearing and be connected to the inner surface of the second bearing. The second connecting shaft and the inner surface of the second bearing may be connected by interference fit, but is not limited thereto.

[0110] In one embodiment, the axis of the second rotating portion 32 may be at the same height as the side of the platform 423 facing away from the base 1 in the second direction Y. This arrangement can ensure that the center point of the display device always remains at the same height during the rotation process, thereby further ensuring the accuracy of the measurement structure.

[0111] In one embodiment of the present disclosure, Figure 1 and Figure 6 As shown, the base 1 can be provided with two bracket positioning grooves 11, and the two bracket positioning grooves 11 can be arranged at intervals along the first direction X. The first bracket 2 and the second bracket 3 can both be connected to the base 1 through the bracket positioning grooves 11, thereby improving the stability of the connection between the first bracket 2 and the base 1 and the stability of the connection between the second bracket 3 and the base 1.

[0112] In one embodiment of the present disclosure, the base 1 may be provided with a plurality of first hollow portions 12, the first bracket 2 may be provided with a plurality of second hollow portions 28, and the second bracket 3 may be provided with a plurality of third hollow portions 34. Such a configuration may further reduce the weight of the optical measurement stand of the display device, and may further save materials for manufacturing the optical measurement stand of the display device, thereby further reducing the cost of measuring the optical characteristics of the display device.

[0113] Another aspect of the present disclosure provides an optical measuring device for a display device. Figures 1 to 6 As shown, the optical measuring device of the display device includes: an optical measuring instrument and an optical measuring stand for the display device. The optical measuring stand for the display device can be the optical measuring stand for the display device described above, and the optical measuring instrument can be arranged on a side of the rotating support platform 4 away from the base 1.

[0114] It should be noted that, since the present disclosure has already elaborated in detail the specific structure and beneficial effects of the optical measuring stand and the optical measuring instrument of the display device in the previous topic, the specific structure and beneficial effects of the optical measuring stand and the optical measuring instrument of the display device will not be repeated in this topic, and the above description can be referred to, which is also within the protection scope of the present disclosure.

When measuring the optical characteristics of the display device, the display device can be placed on the rotating bearing platform 4. In addition, the rotating bearing platform 4 is provided with a positioning portion 41, which can position the center point of the display device, so as to ensure the accuracy of the placement position of the display device on the rotating bearing platform 4, so as to ensure the accuracy of the measurement result.

[0116] At the same time, the rotating bearing platform 4 can be arranged between the first bracket 2 and the second bracket 3, and can be rotatably connected with the first bracket 2 and the second bracket 3. Therefore, when it is necessary to measure the optical characteristics of the display device, the rotating bearing platform 4 can be rotated to change the angle between the display device and the optical measuring instrument, so that the optical characteristics of the display device at various angles can be measured conveniently and quickly. Therefore, the optical measuring device of the display device provided by the present disclosure is more convenient to operate than the prior art, thereby improving the efficiency of measuring the optical characteristics of the display device.

[0117] Furthermore, since the optical measurement stand of the display device is only provided with the base 1, the first bracket 2, the second bracket 3 and the rotating support platform 4, the optical measurement device of the display device provided by the present disclosure has a simpler structure than the prior art, which can reduce the cost of manufacturing the optical measurement device of the display device, thereby effectively reducing the cost of measuring the optical characteristics of the display device.

[0118] In one embodiment of the present disclosure, the optical measuring instrument can be arranged opposite to the positioning portion 41 of the rotating support platform 4 to ensure that the optical measuring instrument can be arranged opposite to the center point of the display device, thereby ensuring the accuracy of the measurement result.
