[0025] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0027] Take the LCD product with integrated touch function as an example. During the production process, it is necessary to bond the touch module to the LCD module. The touch module includes a touch function layer and a cover glass. Specifically, the LCD module and the touch module are bonded by OCA optical adhesive. During the bonding process of the LCD product, there is bonding interface stress between the two bondings. Therefore, there is stress at the bonding interface between the touch module and the LCD module. The LCD module is subjected to the bonding interface stress, which will squeeze the liquid crystal box in the LCD module, resulting in differences in the thickness of the liquid crystal box in different areas. This will cause the color cast of the LCD product, especially the edge thickness of the liquid crystal box will increase, resulting in yellowing of the display edge and other defects.

[0028] There are multiple bonding processes in the production of LCD products, such as the bonding and binding of the LCD module and the touch module, the bonding and binding of the liquid crystal box inside the LCD module itself and other cover plates, such as the bonding and binding of two LCD modules, the bonding and binding of three LCD modules, etc., which are indispensable steps in production and manufacturing. Therefore, the display color cast of LCD products at least includes defects such as yellowing of the display edge caused by the bonding process. At present, the display edge color cast problem is mainly improved by improving the pressure resistance of the liquid crystal box itself and / or increasing the amount of liquid crystal at the edge of the liquid crystal box, but the degree of improvement is limited, and the cost is high and the process is complicated.

[0029] It is understandable that other manufacturing processes of LCD products may also affect the display and cause color cast.

[0030] The embodiments of the present invention provide an optical adjustment device, an optical adjustment method and an optical adjustment system, which can be applied to the case of optically adjusting a display module. No matter what kind of display color cast problem is caused, the present invention can effectively improve the display color cast. Compared with the prior art, there is no need to adjust the pressure resistance of the liquid crystal box, nor to increase the amount of liquid crystal in the liquid crystal box, and the cost is low and the process is simple.

[0031] Figure 1 is a schematic diagram of an optical adjustment device provided by an embodiment of the present invention, Figure 2 yes Figure 1 A schematic diagram of the module is shown in Figure 2. Figure 1 and Figure 2 As shown, the optical adjustment device includes: a display module 100; the display module 100 includes a display module 101 and a first backlight module 102 assembled with the display module 101 after a testing phase; the display module 101 includes a plurality of display partitions 103; the first backlight module 102 includes a plurality of first backlight partitions 104, the first backlight partitions 104 provide backlight for the display partitions 103, and the first backlight module 102 is used to adjust the backlight parameters of the first backlight partitions 104 according to the backlight compensation data of at least one display partition 103 provided by the display module 101 after assembly is completed.

[0032] In this embodiment, the optical adjustment device includes a display module 100, and the display module 100 includes a display module 101 and a first backlight module 102 assembled with the display module 101. It should be noted that the display module 101 after the test is assembled with the first backlight module 102, and the display module 100 formed is a display module 100 that can be actually applied to a liquid crystal display product. When the liquid crystal display product is working, the first backlight module 102 provides backlight to the display module 101 assembled and electrically connected thereto.

[0033] The display module 101 includes a plurality of display partitions 103. The first backlight module 102 includes a plurality of first backlight partitions 104, and the first backlight partitions 104 provide backlight for the display partitions 103. Figure 2As shown, one first backlight partition 104 may be selected to correspond to one display partition 103, and one first backlight partition 104 independently provides backlight for the corresponding display partition 103. Exemplarily, the first backlight partition 104a corresponds to the display partition 103a, and the first backlight partition 104a independently provides backlight for the display partition 103a; the first backlight partition 104b corresponds to the display partition 103b, and the first backlight partition 104b independently provides backlight for the display partition 103b. In other embodiments, one first backlight partition may be selected to correspond to multiple display partitions, and the first backlight partition independently provides backlight for the corresponding multiple display partitions; or, multiple first backlight partitions correspond to one display partition, and the multiple first backlight partitions provide backlight for the corresponding display partition.

[0034] In this embodiment, the optical adjustment device includes a test phase, and the test phase is used to obtain backlight compensation data of the display partition 103 in the display module 101. Specifically, in the test phase, the optical adjustment device provides a test backlight to the display module 101 and obtains the display condition of the display module 101; determines the display data of each display partition 103 according to the display condition of the display module 101; if the display data of the display partition 103 exceeds the allowable color cast range, adjusts the test backlight provided to the display partition 103 until the display data of each display partition 103 is within the allowable color cast range, thereby obtaining the backlight compensation data corresponding to each display partition 103; and stores the backlight compensation data corresponding to the display partition 103 in the display module 101.

[0035] After the test is completed, the display module 101 is assembled with the first backlight module 102, and the display module 101 provides the backlight compensation data corresponding to the display partition 103 to the first backlight module 102. During the operation of the liquid crystal display product, the first backlight module 102 adjusts the backlight parameters of the first backlight partition 104 corresponding to the display partition 103 according to the backlight compensation data of the display partition 103, so that the first backlight partition 104 provides the compensated backlight, thereby realizing the precise adjustment of the display partition 103. Based on this, the display condition of each display partition 103 in the display module 100 is within the allowable color cast range, which effectively improves the display color cast of the display module 100, and can especially improve the yellowing of the display edge of the display module 100.

[0036] It can be understood that the display module 101 can be a liquid crystal display module without light-emitting characteristics, and the display module 101 relies on the light source provided by the backlight module to obtain display performance. Therefore, the display condition of the display module 100 in actual application is mainly determined by the first backlight module 102. The first backlight module 102 controls the first backlight partition 104 to provide compensated backlight, so that the display condition of the display partition 103 is within the allowable color cast range, which can improve the display effect of the display module 100 and improve the display color cast problem.

[0037] The optional display module 101 includes: an array substrate 105, a color filter substrate 106, and a liquid crystal display unit 107 disposed between the array substrate 105 and the color filter substrate 106. The optional liquid crystal display unit 107 includes a liquid crystal layer. Here, the array substrate 105 and the color filter substrate 106 are disposed opposite to each other, and the liquid crystal layer is filled between the array substrate 105 and the color filter substrate 106.

[0038] Exemplarily, the array substrate 105 includes multiple functional structures for driving the liquid crystal to work, such as transistors, pixel electrodes, common electrodes, scanning signal lines, data signal lines and other devices and wiring. The color filter substrate 106 includes a substrate and a black matrix and a color resist layer located on both sides of the substrate, wherein the black matrix is ​​located on the side of the substrate facing the array substrate 105, and the color resist layer is located on the side of the substrate away from the array substrate 105. The black matrix includes multiple openings for defining the light-emitting area of ​​the sub-pixel, and the color resist layer includes red color resist, green color resist and blue color resist. Along the thickness direction of the display module 101, at least part of the color resist is located in the corresponding opening of the black matrix. When the liquid crystal display product is working, a signal is applied to the electrode functional layer in the array substrate 105, so that an electric field that can drive the liquid crystal to work is formed between the array substrate 105 and the color filter substrate 106, and the arrangement state of the liquid crystal molecules is controlled under the action of the electric field. Then, when the light emitted by the light source of the backlight module enters the liquid crystal layer, the light transmittance will be adjusted, and after passing through the color resist, it can be emitted as light of the same color as the color resist, thereby realizing the display of the image.

[0039] In the present invention, the optical adjustment device includes a display module, and the display module includes a display module and a first backlight module assembled with the display module after the test phase; after the backlight is assembled, the display module provides the backlight compensation data corresponding to the display partition to the first backlight module; during actual display, the first backlight module controls the first backlight partition to provide the compensated backlight, so that the display condition of each display partition is within the allowable color cast range, and the precise adjustment of the backlight of each display partition is achieved, which effectively improves the display color cast of the display module, and can especially improve the yellowing of the display edge of the display module, improve the display effect of the display module, and improve the product bonding yield. Compared with the prior art, there is no need to adjust the pressure resistance of the liquid crystal box, nor to increase the amount of liquid crystal in the liquid crystal box, and the cost is low and the process is simple.

[0040] Figure 3 is a schematic diagram of another optical adjustment device provided by an embodiment of the present invention, such as Figure 3 As shown, the optional optical adjustment device also includes: a test module 200, including a test backlight module 201 assembled with the display module 101 during a test phase; the test backlight module 201 includes a plurality of second backlight partitions, the test module 200 is used to provide a test backlight for the display module 101 using the test backlight module 201, and when it is detected that the actual display data of the display partition 103 is within the allowable color cast range of the reference display data, the backlight parameters of the corresponding second backlight partition are determined as the backlight compensation data of the display partition 103.

[0041] The optional test module 200 provides test backlight for multiple display modules 101 in a time-sharing manner.

[0042] The optional test module 200 also includes: an image acquisition module 202 ; the image acquisition module 202 is used to acquire the display image of the display module 101 to obtain the reference display data and the actual display data of the display partition 103 .

[0043] In this embodiment, the optical adjustment device includes a test module 200. Specifically, the test module 200 includes a stage 203, a test backlight module 201 and an image acquisition module 202.

[0044] The test backlight module 201 is mounted on the carrier 203. The optional test backlight module 201 can be detachably mounted on the carrier 203, and the corresponding test backlight module 201 can be configured in the test module 200 according to the size change of the display module 101, so as to meet the test of display modules 201 of different sizes. In the test phase, the display module 101 is assembled with the adapted test backlight module 201 to perform the test.

[0045] The image acquisition module 202 is disposed above the stage 203. After the display module 101 is assembled with the test backlight module 201 on the stage 203, the display module 101 faces the image acquisition module 202, and the image acquisition module 202 can shoot to acquire an image of the display module 101. The optional image acquisition module 202 at least includes a camera, but is not limited thereto.

[0046] The stage 203 may be a moving stage, and the stage 203 can be displaced in the vertical and horizontal directions; and / or the image acquisition module 202 may be mounted on a moving bracket, and the moving bracket can be displaced in the vertical and horizontal directions. Based on this, the relative position between the image acquisition module 202 and the test backlight module 201 can be adjusted.

[0047] The testing module 200 includes a testing backlight module 201 assembled with the display module 101 during the testing phase; the testing backlight module 201 includes a plurality of second backlight partitions.

[0048] For the same display module 101, the test backlight module 201 assembled in the test phase and the first backlight module 102 assembled after the test phase can be the same two backlight modules. Exemplarily, for multiple identical display modules 101, multiple identical first backlight modules 102 are provided, one of the first backlight modules 102 is installed on the carrier 203 as the test backlight module 201, and the test backlight module 201 is used to provide test backlight for multiple display modules 101 in a time-sharing manner.

[0049] Alternatively, for the same display module 101, the test backlight module 201 assembled in the test phase and the first backlight module 102 assembled after the test phase may be two backlight modules with different backlight area sizes, wherein the backlight area of ​​the test backlight module 201 is larger than the backlight area of ​​the first backlight module 102. Exemplarily, Figure 4 is a schematic diagram of a test backlight module provided by an embodiment of the present invention, such as Figure 4 As shown, the optional test backlight module 201 includes a first area 211 and a second area 212, wherein the first area 211 includes a plurality of second backlight subareas 213, and the second area 212 includes a plurality of backlight subareas, and the plurality of second backlight subareas 213 of the first area 211 completely correspond to and are identical to the plurality of first backlight subareas 104 of the first backlight module 102. In the test phase, the first area 211 of the test backlight module 201 is used to provide test backlight for a plurality of identical display modules 101 in a time-sharing manner.

[0050] Alternatively, the first backlight module can be reused as a test backlight module. For the same display module 101, the test backlight module 201 assembled during the test phase and the first backlight module 102 assembled after the test phase can be the same backlight module. Specifically, for the display module 101 and its corresponding first backlight module 102, during the test phase, the first backlight module 102 is installed on the carrier 203 as the test backlight module 201, the first backlight module 102 is used to provide the test backlight for the display module 101 and the backlight compensation data obtained from the test is written into the first backlight module 102. After the test is completed, the assembled display module 101 and the first backlight module 102 enter the subsequent process.

[0051] As described above, the test backlight module can be an independent backlight module, which is only used to provide test backlight for different display modules; or the first backlight module to be assembled with the display module can be reused as the test backlight module. This can improve the flexibility of the optical adjustment device and is conducive to its application in the testing of different display modules.

[0052] The optional test module is used to drive the display module to display the first color picture. The optional reference display data is the theoretical display data of the display image of the display module; or, the reference display data is the actual display data of the central display partition of the display module.

[0053] In this embodiment, during the test phase, the test module provides a test backlight, and the display module applies a driving voltage to the display module, so that the picture displayed by the assembled test backlight module and the display module is a first color picture, and the first color picture is a pure color picture, such as a white picture. When the liquid crystal display product displays a white picture, the brightness of the ambient light accounts for a small proportion, that is, the influence of the ambient light on the chromaticity of the picture can be ignored. Therefore, during the test phase, the picture displayed by the assembled test backlight module and the display module can be selected as a white picture, which is conducive to reducing the influence of ambient light on the test and improving the backlight compensation accuracy. Sequentially, the image acquisition module acquires the display image of the display module, obtains the image of the display area of ​​the display module after image processing, and then obtains the actual display data of each display partition according to the image analysis of the display area of ​​the display module, and compares the actual display data of the display partition with the reference display data.

[0054] For any display partition, if the color cast of the actual display data of the display partition relative to the reference display data exceeds the preset allowable color cast range, the test backlight module independently adjusts the backlight parameters of the second backlight partition corresponding to the display partition, so that the test backlight provided by the second backlight partition changes. Sequentially, the image acquisition module captures the display image of the display module again, and compares the actual display data of the display partition with the reference display data. If the color cast of the actual display data of the display partition relative to the reference display data is within the preset allowable color cast range, the backlight parameters of the second backlight partition corresponding to the display partition can be determined as the backlight compensation data corresponding to the display partition. In this way, by independently and accurately adjusting each second backlight partition, the backlight compensation data of each display partition can be obtained.

[0055] It should be noted that the benchmark display data for comparison with the actual display data can be obtained in a variety of different ways. The optional benchmark display data is the theoretical display data of the display image of the display module. Exemplarily, in the test phase, the picture displayed by the assembled test backlight module and the display module is a white picture, and the theoretical display data of the white picture is determined as the benchmark display data, and the theoretical display data of the white picture can be the calibrated initial driving voltage corresponding to the highest grayscale of the display module. But not limited to this. Alternatively, the optional benchmark display data is the actual display data of the central display partition of the display module. Exemplarily, in the test phase, the picture displayed by the assembled test backlight module and the display module is a white picture, and the actual display data of a display partition in the central area of ​​the white picture is determined as the benchmark display data, or the average value of the actual display data of multiple display partitions in the central area of ​​the white picture is determined as the benchmark display data.

[0056] As described above, the stage and the image processing module can be integrated in the face scanning test equipment, and the stage of the face scanning test equipment is equipped with a test backlight module. The brightness uniformity of the backlight source of the optional test backlight module can reach more than 95%, and the color uniformity deviation is within the range of ±0.001, which can reduce the impact of the test backlight module itself on the test process and provide test accuracy.

[0057] The optional test module also includes: a coordinate partitioning module, which is used to establish a first coordinate system, display the display image of the display module in the first coordinate system, make the coordinate information of the display image coincide with the coordinate information of the backlight area of ​​the test backlight module, and determine the second backlight partition corresponding to the display partition based on the coordinate correspondence between the display partition and the second backlight partition.

[0058] As described above, the coordinate partitioning module may be integrated into the face scanning test device, or the coordinate partitioning module may be integrated into a host computer, and the host computer is electrically connected to the face scanning test device.

[0059] Specifically, the coordinate partitioning module establishes a first coordinate system, and then displays the display image of the display module obtained by the image acquisition module in the first coordinate system, and also projects the backlight area of ​​the test backlight module into the first coordinate system, so that the coordinate range of the display image coincides with the coordinate range of the backlight area of ​​the test backlight module, that is, in the first coordinate system, the boundary coordinate information of the display image coincides with the boundary coordinate information of the backlight area.

[0060] The host computer analyzes the display image to find out the abnormal display partitions that exceed the allowable color cast range, and extracts the coordinate information of the abnormal display partitions that exceed the allowable color cast range through the first coordinate system, wherein the coordinate information of the abnormal display partition can be determined according to the distance between the abnormal display area and the edge of the display image. It can be understood that the coordinate information of the abnormal display partition that exceeds the allowable color cast range is the coordinate information of the second backlight partition to be adjusted in the test backlight module. The test backlight module determines the second backlight partition and adjusts the backlight parameters of the second backlight partition based on the coordinate information of the abnormal display partition that exceeds the allowable color cast range. Until the display data of the display partition is within the allowable color cast range, the backlight parameters of the corresponding second backlight partition are determined as the backlight compensation data corresponding to the display partition.

[0061] In this embodiment, a color cast test is performed on the bonded display module before leaving the factory, and the backlight compensation data obtained from the test is written into the first backlight module assembled with the display module. In actual use, the first backlight module adjusts the corresponding first backlight partition according to the backlight compensation data of the display partition, so that the first backlight partition provides backlight according to the corresponding backlight compensation data, which can improve the display color cast problem, especially the display edge yellowing and other display problems. Compared with the prior art, there is no need to adjust the pressure resistance of the liquid crystal box, nor to increase the amount of liquid crystal in the liquid crystal box, which can effectively improve the display edge yellowing problem, and the cost is low and the process is simple.
