Description

Technical Field

[0001] The present invention relates to the field of display technology, and more particularly to a liquid crystal display module, a display device, and a light compensation method. Background Art

[0002] The display principle of liquid crystal display (LCD) products is to achieve different display effects by controlling the angle of liquid crystal deflection by changing the voltage difference between the electrodes on both sides of the liquid crystal.

[0003] Current LCD products with under-display cameras typically employ a punch-hole or teardrop design due to the difficulty in achieving the required transmittance. Panel wiring is carefully designed to avoid the perforated or teardrop-shaped areas near the camera. Furthermore, the camera module design is significantly limited due to the size of the perforated hole. Consequently, due to the limitations of the perforated hole and the display, products with under-display cameras often experience lower camera quality. Summary of the Invention

[0111] In order to more clearly illustrate the present invention, the present invention will be further described below in conjunction with the embodiments and drawings. Similar components in the drawings are represented by the same reference numerals. It should be understood by those skilled in the art that the following specific description is illustrative rather than restrictive and should not be used to limit the scope of protection of the present invention.

[0112] Current LCD products with under-display cameras typically employ a punch-hole or teardrop design due to the difficulty in achieving the required transmittance. Panel wiring is carefully designed to avoid the perforated or teardrop-shaped areas near the camera. Furthermore, the camera module design is significantly limited due to the size of the perforated hole. Consequently, due to the limitations of the perforated hole and the display, products with under-display cameras often experience lower camera quality.

[0113] Based on the related art that the light at the through-hole structure position of the liquid crystal display module is poor, which leads to the problem of low shooting quality when using the under-screen camera module, the present invention proposes a liquid crystal display module, a display device and a light compensation method to solve the above problem.

[0114] The first embodiment of the present invention provides a liquid crystal display module, such as Figures 1 to 3 As shown, the liquid crystal display module includes a display area AA, a through hole 01, and a compensation area BB at least partially surrounding the through hole 01. The through hole 01 and the compensation area BB are both non-display areas, that is, these areas do not have a display function. Figure 1As shown, the through hole 01 is located at the edge of the display area AA, and the compensation area BB is designed to be a U-shaped structure around the edge of the through hole 01. Figure 2 As shown, the through hole 01 is located inside the display area AA, and the compensation area BB is a ring structure surrounding the through hole 01. Figure 3 As shown, the through hole 01 is an arc-shaped structure located at the edge of the display area AA, and the compensation area BB is a semi-annular structure. Therefore, the position of the through hole 01 and the structure of the compensation area BB can be designed according to different requirements.

[0115] Now Figure 2 The circular through hole shown is an embodiment to illustrate the structure of the liquid crystal display module of the embodiment of the present invention. In an optional embodiment, as shown in FIG. Figure 4 As shown,

[0116] The liquid crystal display module includes a first substrate 10, a second substrate 20 opposite to the first substrate 10, and a liquid crystal layer 30 located between the first substrate 10 and the second substrate 20, wherein the through hole 01 includes a hole that passes through the first substrate 10, the liquid crystal layer 30 and the second substrate 20.

[0117] In an optional embodiment, the first substrate 10 is a liquid crystal display substrate, which realizes the emission of liquid crystal display by changing the driving voltage, and the second substrate 20 is a color filter substrate, which realizes the emission of light of different colors.

[0118] In an optional embodiment, if Figure 4 As shown,

[0119] The first substrate 10 includes:

[0120] a display substrate 11 corresponding to the display area AA, for emitting display light; and

[0121] A compensation substrate 12 corresponding to the compensation area BB, the compensation substrate 12 including a compensation circuit (not shown in the figure) for performing optical compensation on the through hole 01 in response to a compensation signal output by a driving chip;

[0122] The second substrate 20 includes:

[0123] The first color filter layer 21 corresponding to the display substrate 11 is used to filter the display light.

[0124] The liquid crystal display module of the embodiment of the present invention provides a compensation substrate 12 in the compensation area BB and a compensation circuit on the compensation substrate 12, and utilizes the compensation circuit to perform optical compensation on the position of the through hole 01, thereby improving the optical compensation effect and further improving the imaging quality of the camera module applied at the through hole 01.

[0125] Example 1

[0126] In an optional embodiment, if Figure 5 As shown, the display substrate 11 includes a first substrate 111, a first drive electrode 112 located on the first substrate 111, and a second drive electrode 113 insulated from the first drive electrode 112. The liquid crystal layer 30 includes a display liquid crystal layer 31 corresponding to the display area AA, which is driven by the first drive electrode 112 and the second drive electrode 113. For the display substrate 11, the liquid crystal deflection of the display liquid crystal layer 31 is controlled by changing the voltage difference between the first drive electrode 112 and the second drive electrode 113, thereby achieving brightness control of the display area AA.

[0127] In an optional embodiment, if Figure 5 As shown, the first color filter layer 21 includes a first color resist layer 211, a second color resist layer 212, a third color resist layer 213, and a black matrix (not shown) located between the two color resist layers of different colors. The first color filter layer 21 is disposed on the surface of the display liquid crystal layer 31 away from the first substrate 111. For example, the first color resist layer 211 is red, the second color resist layer 212 is green, and the third color resist layer 213 is blue, thereby achieving color display.

[0128] In an optional embodiment, if Figure 6 As shown, the compensation substrate 12 includes a second substrate 121,

[0129] The compensation circuit includes a first compensation electrode 122 located on the second substrate 121 and a second compensation electrode 123 insulated from the first compensation electrode 122;

[0130] The liquid crystal layer 30 further includes a compensation liquid crystal layer 32 corresponding to the compensation area BB and driven by the first compensation electrode 122 and the second compensation electrode 123 .

[0131] Based on the liquid crystal display principle, the display substrate 11 and the compensation substrate 12 of the embodiment of the present invention have different functions. The display substrate 11 realizes the display of the display area AA, and the compensation substrate 12 also uses the deflection of the liquid crystal to change with the change of voltage to realize the light modulation characteristics and achieve different light compensation.

[0132] In an optional embodiment, the first substrate 111 and the second substrate 121 are provided in the same layer.

[0133] The first driving electrode 112 and the first compensation electrode 122 are arranged on the same layer.

[0134] The second driving electrode 113 and the second compensation electrode 123 are arranged on the same layer.

[0135] The display liquid crystal layer 31 and the compensation liquid crystal layer 32 are disposed in the same layer.

[0136] The same-layer arrangement described in the embodiment of the present invention is to form the same material layer on the same film surface using different processes. The material layer forms different structures at different positions. This arrangement can improve process efficiency.

[0137] In an optional embodiment, the first driving electrodes 112 and the second driving electrodes 113 can adopt an advanced superdimensional switching display mode (ADS), a twisted nematic (TN) display mode, or a vertical alignment (VA) display mode, which has a wide range of applications. Similarly, the first compensation electrodes 122 and the second compensation electrodes 123 can also adopt an advanced superdimensional switching display mode (ADS), a twisted nematic (TN) display mode, or a vertical alignment (VA) display mode, which has a wide range of applications.

[0138] In a specific embodiment of light compensation, no color resist layer of any color is disposed at a position of the second substrate 20 corresponding to the compensation area BB.

[0139] This embodiment is an example of the first embodiment, and takes the compensation substrate 12 in the ADS mode as an example to illustrate the electrodes in the compensation area BB. Figure 7 As shown, in this display mode, the orthographic projections of the first compensation electrode 122 and the second compensation electrode 123 on the second substrate 121 do not overlap, for example Figure 7 As shown, the first compensation electrodes 122 and the second compensation electrodes 123 are alternately arranged in the same row direction and the same column direction. All the first compensation electrodes 122 are connected to the same first voltage signal V1 through metal wires, and all the second compensation electrodes 123 are connected to the same second voltage signal V2 through metal wires, thereby realizing the voltage driving design of the compensation area BB.

[0140] like Figure 7 As shown, color resist layers of various colors, such as a first color resist layer 211, a second color resist layer 212, and a third color resist layer 213, are provided on the first color filter layer 21 of the display area AA to achieve color display. However, unlike the display area AA, the compensation area BB is not provided with a color resist layer. With this arrangement, the light in the compensation area BB is white light for optical compensation.

[0141] like Figure 7As shown, the display substrate 11 includes Gate lines extending horizontally and Data lines extending vertically. The Gate lines and the Data lines intersect to form a region defining a sub-pixel. The Gate lines transmit gate drive signals and the Data lines transmit data signals to realize the driving of the display substrate.

[0142] In an optional embodiment, if Figure 8 As shown, the liquid crystal display module further includes:

[0143] A first backlight module 41 corresponding to the display substrate 11 is provided on a side of the display substrate 11 away from the display liquid crystal layer 31 . The first backlight module 41 is used to provide display light to the display area AA.

[0144] The second backlight module 42 corresponding to the compensation substrate 12 is disposed on a side of the compensation substrate 12 away from the compensation liquid crystal layer 32 . The second backlight module 42 is used to provide compensation light to the compensation area BB.

[0145] In an optional embodiment, the first backlight module 41 and the second backlight module 42 are of an integrated design, that is, the first backlight module 41 and the second backlight module 42 are the same module structure, and the "first" and "second" are only used to numerically limit and indicate different setting areas, and the two are an integral structure.

[0146] Or, in another optional embodiment, as Figure 8 As shown, the first backlight module 41 and the second backlight module 42 are designed as independent structures, that is, the first backlight module 41 and the second backlight module 42 are designed separately. For example, the plastic frame of the first backlight module 41 and the plastic frame of the second backlight module 42 are fixed to the same substrate, for example Figure 8 Fixing is achieved on the metal substrate 50 shown.

[0147] In this embodiment, the brightness of the second backlight module 42 is greater than that of the first backlight module 41, that is, the second backlight module 42 uses LED lamp beads with higher brightness, and adjusts the electrode voltage of the compensation area BB as needed to change the deflection of the compensation liquid crystal layer 32 to achieve light compensation of different brightness.

[0148] Based on the above-mentioned structural design of the first backlight module 41 and the second backlight module 42, those skilled in the art can design according to actual applications. Those skilled in the art can choose any structural design of the first backlight module 41 and the second backlight module 42, which will not be repeated here.

[0149] Based on the light design scheme of the first embodiment of the present invention, the display area AA and the compensation area BB need to be controlled by separate circuits. According to the need for light compensation, the backlight of the compensation area BB is turned on or off, and the compensation light intensity of the compensation area BB is controlled.

[0150] The circuit of the liquid crystal display module corresponding to the first embodiment of the present invention is now described.

[0151] In an optional embodiment, the display substrate 11 further includes a first light control circuit (not shown in the figure) for lighting the first backlight module 41 in response to the display signal;

[0152] The compensation substrate 12 further includes:

[0153] at least one photosensitive circuit, configured to sense light at the position of the through hole 01 and generate optical data to the driver chip, so that the driver chip generates the compensation signal; and

[0154] The second light control circuit (not shown in the figure) is used to light up the second backlight module 42 in response to the compensation signal generated by the driving chip.

[0155] The first compensation electrode 122 and the second compensation electrode 123 are used to drive the compensation liquid crystal layer 32 to perform light compensation according to the compensation signal.

[0156] In the embodiment of the present invention, the first light control circuit and the second light control circuit designed in a partitioned manner control the light output of the corresponding backlight module, the light sensing circuit realizes the transmission of optical data, and the connecting wires realize the control of the driving chip and each compensation electrode. Through the joint design of the above circuits, light compensation of the compensation area BB and normal display of the display area AA are realized.

[0157] In an optional embodiment, if Figure 9 As shown, the liquid crystal display module further includes a driving chip 60, and the driving chip 60 includes: a first connecting terminal 61 connected to the display substrate 11, a second connecting terminal 62 connected to the compensation substrate 12, a first light-control terminal (not shown in the figure) connected to the first light-control circuit, and a second light-control terminal (not shown in the figure) connected to the second light-control circuit.

[0158] Among them, Figure 9 As shown, the first connection terminal 61 includes a first electrode connection terminal, which is respectively connected to the first driving electrode 112 and the second driving electrode 113; the second connection terminal 62 includes a second electrode connection terminal, which is respectively connected to the first compensation electrode 122 and the second compensation electrode 123.

[0159] The embodiment of the present invention designs the connection between the driver chip 60 and each circuit. Through this setting, the connection design of each circuit is realized to ensure the normal display function and light compensation function of the liquid crystal display module.

[0160] Based on the first embodiment, the present invention further proposes a second embodiment for performing optical compensation according to ambient light, which is detailed in the following embodiment.

[0161] Example 2

[0162] In an optional embodiment, if Figure 10 As shown, the photosensitive circuit 124 includes:

[0163] The first photosensitive device 1241 located on the second substrate 121 is used to sense the first color light at the position of the through hole 01 to generate first color light sensing data;

[0164] The second photosensitive device 1242 located on the second substrate 121 is used to sense the second color light at the position of the through hole 01 to generate second color light sensing data;

[0165] The second substrate 20 further includes a second color filter layer 22 corresponding to the compensation substrate 12.

[0166] The second color filter layer 22 includes a light shielding layer 221 arranged at a position corresponding to the second photosensitive device 1242 , and the orthographic projection of the light shielding layer 221 on the second substrate 121 covers the orthographic projection of the second photosensitive device 1242 on the second substrate 121 .

[0167] The photosensitive circuit 124 of the embodiment of the present invention utilizes the characteristic that the leakage current Ioff of the photosensitive device changes after being exposed to light. By comparing the current difference between the first color light sensing data and the second color light sensing data, it reflects the changes in the surrounding light environment, realizes the function of a light sensor, and achieves the effect of automatic light compensation according to the difference in ambient light.

[0168] Unlike the structural design of the first embodiment in which the second color filter layer 22 is not provided, the embodiment of the present invention utilizes the original film layer structure of the liquid crystal display module for design, and further designs the color filter layer of the compensation area BB. A light-shielding layer 221 is provided in the second color filter layer 22 at the position corresponding to the compensation substrate 12 to block the second photosensitive device 1242. The first photosensitive device 1241 can receive ambient light, and the second photosensitive device 1242 will not feel the ambient light under the shielding of the light-shielding layer 221, thereby achieving light contrast.

[0169] The light-shielding layer 221 of this embodiment can be provided on the same layer as the black matrix of the first color filter layer 21 , that is, when the black matrix of the first color filter layer 21 is manufactured using the same process, the light-shielding layer 221 can be simultaneously formed above the second photosensitive device 1242 , thereby improving process efficiency.

[0170] In an optional embodiment, if Figure 10 or Figure 11 As shown,

[0171] The first photosensitive device 1241 includes a first end, a second end and a third end;

[0172] The second photosensitive device 1242 includes a fourth end, a fifth end, and a sixth end;

[0173] The first end and the fourth end are connected to the same first node A1 to access the first start signal QD1 that controls each photosensitive device to perform sensing.

[0174] The second end and the fifth end are connected to the same second node A2 to access the second start signal QD2 for controlling each photosensitive device to perform sensing.

[0175] The third terminal and the sixth terminal are connected to the driver chip 60, for example, Figure 10 As shown, the third end is connected to the driving chip 60 through the data transmission line M1, and the sixth end is connected to the driving chip 60 through the data transmission line M2 to transmit corresponding color sensing data.

[0176] Specifically, during light compensation, the driver chip 60 outputs various signals required for light compensation. For example, the first terminal of the first photosensitive element 1241 receives the first start signal QD1 output by the driver chip 60, and the fourth terminal receives the second start signal QD2 output by the driver chip 60. When the first and second terminals are conductive, the first photosensitive element 1241 senses the light and transmits color data via the third terminal, allowing the driver chip 60 to generate a compensation signal based on the sensed data. The second photosensitive element 1242 operates in a similar manner, except that it senses light data after being blocked.

[0177] In an optional embodiment, the first photosensitive device 1241 and the second photosensitive device 1242 are thin-film drive transistors, which are relatively low in cost. The first photosensitive device 1241 and the second photosensitive device 1242 can be designed on the same layer as the thin-film drive transistors of the display substrate 11, which simplifies the structure and improves process efficiency. For example, when the photosensitive device is a thin-film drive transistor, the first and fourth terminals are gates, the second and fifth terminals are sources, and the third and sixth terminals are drains.

[0178] The second embodiment of the present invention also requires designing the connection between the compensation area BB and the driver chip 60.

[0179] In an optional embodiment, if Figure 11 As shown, when the display module further includes a photosensitive circuit 124 , the driving chip 60 further includes a third connecting terminal 63 connected to the photosensitive circuit 124 , which is connected to each photosensitive device respectively.

[0181] The third connection terminal 63 includes:

[0182] a first sensing connection terminal connected to the third terminal of the first light sensing device 1241;

[0183] The second sensing connection terminal connected to the sixth terminal of the second photosensitive device 1242 transmits various sensing data to the driving chip 60 through the third connection terminal 63 .

[0184] like Figure 10 As shown, there can be multiple photosensitive circuits 124, forming a structure surrounding the through hole 01, sensing the ambient light at different positions of the through hole 01, thereby improving the sensing accuracy and further improving the compensation effect.

[0185] Based on the design of the above-mentioned embodiment 2, the embodiment of the present invention further designs and proposes embodiment 3 on the basis of detecting ambient light, so that the photosensitive circuit 124 has the function of detecting each light color in the ambient light, further improving the compensation effect. The embodiment 3 of the present invention is now described.

[0191] Wherein, the second color filter layer 22 further includes:

[0192] a fourth color resist layer 222 disposed at a position corresponding to the third photosensitive device 1243 , wherein the orthographic projection of the fourth color resist layer 222 on the second substrate 121 covers the orthographic projection of the third photosensitive device 1243 on the second substrate 121 ;

[0193] a fifth color resist layer 223 disposed at a position corresponding to the fourth photosensitive device 1244 , wherein the orthographic projection of the fifth color resist layer 223 on the second substrate 121 covers the orthographic projection of the fourth photosensitive device 1244 on the second substrate 121 ;

[0194] The sixth color resist layer 224 is disposed at a position corresponding to the fifth photosensitive device 1245 , and the orthographic projection of the sixth color resist layer 224 on the second substrate 121 covers the orthographic projection of the fifth photosensitive device 1245 on the second substrate 121 .

[0195] Based on the design of the light-shielding layer 221 in the second embodiment, this solution not only provides a light-shielding layer 221 in the second color filter layer 22 corresponding to the position of the compensation substrate 12 to block the second photosensitive device 1242, and not only does not provide a blocking layer at the position of the first photosensitive device 1241, but further provides color-resistance layers of different colors at the positions of the third photosensitive device 1243, the fourth photosensitive device 1244 and the fifth photosensitive device 1245. The first photosensitive device 1241 can receive ambient light, the second photosensitive device 1242 will not feel the ambient light under the shielding of the light-shielding layer 221, and the third photosensitive device 1243, the fourth photosensitive device 1244 and the fifth photosensitive device 1245 can feel ambient light of different colors under the shielding of each color-resistance layer, thereby achieving light contrast.

[0196] Therefore, the photosensitive circuit 124 of the embodiment of the present invention utilizes the characteristic that the leakage current Ioff of the photosensitive device changes after being exposed to light, combined with the solution of designing the second color filter layer 22 of the compensation area BB with color resist layers of different colors, so that the photosensitive devices at different color resist layer positions sense different data. By comparing the different sensed data, it can reflect the light quality of red light, green light, and blue light in the surrounding ambient light, thereby realizing the function of a light sensor, which has the function of automatically performing light compensation and color compensation according to the ambient light.

[0197] Illustratively, the light-shielding layer 221 of this embodiment can be arranged on the same layer as the black matrix of the first color filter layer 21, and the color resist layers of each color can be arranged on the same layer as the color resist layers of each color of the first color filter layer 21. For example, when the black matrix of the first color filter layer 21 is produced using the same process, the light-shielding layer 221 can be simultaneously formed above the second photosensitive device 1242, thereby improving process efficiency.

[0198] In an optional embodiment, if Figure 12 and Figure 13 As shown,

[0199] The third photosensitive device 1243 includes a seventh end, an eighth end, and a ninth end;

[0200] The fourth photosensitive device 1244 includes a tenth end, an eleventh end, and a twelfth end;

[0201] The fifth photosensitive device 1245 includes a thirteenth terminal, a fourteenth terminal, and a fifteenth terminal;

[0202] The first terminal, the fourth terminal, the seventh terminal, the tenth terminal, and the thirteenth terminal are connected to the same first node A1 to receive a first start signal QD1 for controlling each photosensitive device to perform sensing.

[0203] The second terminal, the fifth terminal, the eighth terminal, the eleventh terminal and the fourteenth terminal are connected to the same second node A2 to access the second start signal QD2 for controlling each photosensitive device to perform sensing.

[0204] The third terminal, the sixth terminal, the ninth terminal, the twelfth terminal, and the fifteenth terminal are respectively connected to the driving chip 60 to transmit corresponding color sensing data.

[0205] In one specific example, the driver chip 60 outputs various signals requiring light compensation. For example, the seventh terminal of the third photosensitive device 1243 receives the first start signal QD1 output by the driver chip 60, and the eighth terminal receives the second start signal QD2 output by the driver chip 60. When the seventh and eighth terminals are conductive, the third photosensitive device 1243 senses the light and transmits color data via the ninth terminal, allowing the driver chip 60 to generate a compensation signal based on the sensed data. The fourth and fifth photosensitive devices 1244 and 1245 operate in a similar manner, except that they sense light data of different colors.

[0206] In an optional embodiment, the third photosensitive device 1243, the fourth photosensitive device 1244, and the fifth photosensitive device 1245 are thin-film drive transistors, which are relatively low in cost. The third photosensitive device 1243, the fourth photosensitive device 1244, and the fifth photosensitive device 1245 can be designed on the same layer as the thin-film drive transistors of the display substrate 11, which simplifies the structure and improves process efficiency. For example, when the photosensitive devices are thin-film drive transistors, the seventh, tenth, and thirteenth terminals are gates, the eighth, eleventh, and fourteenth terminals are sources, and the ninth, twelfth, and fifteenth terminals are drains.

[0207] The third embodiment of the present invention also requires designing the connection between the compensation area BB and the driver chip 60.

[0208] The photosensitive circuit 124 further includes a third photosensitive device 1243, a fourth photosensitive device 1244 and a fifth photosensitive device 1245.

[0209] The third connection terminal 63 further includes:

[0210] a third sensing connection terminal connected to the ninth terminal of the third photosensitive element 1243;

[0211] a fourth sensing connection terminal connected to the twelfth terminal of the fourth photosensitive element 1244;

[0212] The fifth sensing connection terminal connected to the fifteenth terminal of the fifth photosensitive device 1245 transmits the sensing data generated by each photosensitive device to the driving chip 60 through the third connection terminal 63 .

[0213] In the embodiment of the present invention, color resist layers of various colors are provided in the compensation area BB. The color resist layers have different design schemes, with the photosensitive circuit 124 detecting red light, green light, and blue light as the design principle. The distribution of the color resist layers in the embodiment of the present invention is now described.

[0214] In an optional embodiment, if Figure 12 As shown,

[0215] The center of the orthographic projection of the fourth color resist layer 222 , the fifth color resist layer 223 and the sixth color resist layer 224 on the second substrate 121 coincides with the center of the through hole 01 .

[0216] The orthographic projections of the fourth color-resistance layer 222 , the fifth color-resistance layer 223 and the sixth color-resistance layer 224 on the second substrate 121 are ring-shaped structures;

[0217] The color resist layer at a position corresponding to the first photosensitive device 1241 has a first via structure to expose a surface of the first photosensitive device 1241 close to the color resist layer and away from the second substrate 121;

[0218] The color resist layer at a position corresponding to the second photosensitive device 1242 has a second via structure, and the light shielding layer 221 is disposed in the second via structure.

[0219] The fourth color resist layer 222, the fifth color resist layer 223 and the sixth color resist layer 224 of the embodiment of the present invention are designed as annular with overlapping centers, which can detect the difference of light of each color in the annular area of the entire through hole 01. In this embodiment, the third photosensitive device 1243, the fourth photosensitive device 1244 and the fifth photosensitive device 1245 are respectively arranged at the positions of the color resist layers of corresponding colors, such as Figure 13 As shown, the photosensitive circuit 124 also includes a first photosensitive device 1241 and a second photosensitive device 1242. No film layer is set on the first photosensitive device 1241, and a light-shielding layer 221 is set on the second photosensitive device 1242. Therefore, in this embodiment, the fourth color-resistance layer 222, the fifth color-resistance layer 223 and the sixth color-resistance layer 224 in an annular shape on the outside of the through hole 01 need to be designed.

[0220] Exemplarily, the fourth color resist layer 222 is a red color resist layer, the fifth color resist layer 223 is a green color resist layer, and the sixth color resist layer 224 is a blue color resist layer. If the first photosensitive device 1241 is arranged on the compensation substrate 12 covered by the projection of the red color resist layer, then a first via structure is set in the red color resist layer above the first photosensitive device 1241 to expose the first photosensitive device 1241 so that the first photosensitive device 1241 can directly detect unfiltered ambient light. For example, if the second photosensitive device 1242 is located on the compensation substrate 12 covered by the projection of the blue color resist layer, then a second via structure is set in the blue color resist layer above the second photosensitive device 1242, and a light-shielding layer 221 is set in the second via structure so that the second photosensitive device 1242 does not detect any ambient light, thereby realizing data comparison of each color light.

[0221] Therefore, the first photosensitive device 1241 and the second photosensitive device 1242 of the embodiment of the present invention can be arranged at the position where the color resist layer of any color is located, such as Figure 12 The projection position of the photosensitive circuit 124 shown in FIG. Figure 13 The device connection diagrams shown are for illustrative purposes only. Those skilled in the art can design according to actual applications to form a photosensitive circuit 124 with various photosensitive devices as shown below. Figure 13 The circuit configuration shown is a design guideline.

[0223] The center of the orthographic projection of the fourth color resist layer 222 , the fifth color resist layer 223 and the sixth color resist layer 224 on the second substrate 121 coincides with the center of the through hole 01 ;

[0224] The color resist layer at a position corresponding to the first photosensitive device 1241 has a third via structure to expose a surface of the first photosensitive device 1241 close to the color resist layer and away from the second substrate 121;

[0225] The color resist layer at a position corresponding to the second photosensitive device 1242 has a fourth via structure, and the light shielding layer 221 is disposed in the fourth via structure.

[0226] In the embodiment of the present invention, the color resist layers of each color are designed as fan rings, and the ends are connected to form the following Figure 14 The complete circular structure shown, that is, the color resist layer of each color detects the color difference in the ambient light in a certain sector-shaped area of the through hole 01 .

[0227] In this embodiment, the designs of the first photosensitive device 1241 and the second photosensitive device 1242 are the same as the aforementioned ring-shaped color resist layer, which will not be described in detail here.
