Description

Technical Field

[0002] With the promotion of large-size display screens and folding screens, PLP (Pol Less Panel, Chinese abbreviation: removing the polarizer from the display panel) technology is now introduced. PLP technology uses BM (Black Matrix, Chinese abbreviation: black matrix) to block the non-pixel area and CF (Color Filter, Chinese abbreviation: color filter) to block the pixel area; since the light shielding property of BM and the light transmittance of CF are higher than those of polarizers, it can achieve the dual effects of reducing reflection and reducing power consumption. Taking mobile phones as an example, IR holes (photosensitive holes) are usually set on the mobile phone display screen, and sensors such as light sensors, distance sensors, camera photosensors, etc. are set at the positions corresponding to the IR holes; at the positions of the IR holes, the reflectivity of the light at the positions covered by CF and those not covered by CF is different, so when the screen is off, there will be visual differences in the display panel at the positions of the IR holes.

[0047] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0048] The embodiments of the present application provide a display panel 100 and a display device. The following are detailed descriptions of each. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0049] In a first aspect, an embodiment of the present application provides a display panel 100. Figure 1 , Figure 2 and Fig.18 The display panel 100 has a first display area A and a second display area B located outside the first display area A, the transmittance of the first display area A is greater than the transmittance of the second display area B; the display panel 100 includes an array substrate 1, a light-emitting functional layer 2 and a color filter layer 3; the array substrate 1; the light-emitting functional layer 2 is arranged on the array substrate 1, and the light-emitting functional layer 2 includes a plurality of light-emitting units 21 arranged in an array; the color filter layer 3 is arranged on the light-emitting functional layer 2, and the color filter layer 3 includes a plurality of color resists 31, and each of the color resists 31 corresponds to the position of one of the light-emitting units 21; wherein the display panel 100 also includes a plurality of dimming structures 4, at least in the first display area A, the dimming structure 4 is arranged between two adjacent color resists 31, and the dimming structure 4 is used to adjust the reflectivity of ambient light.

[0050] In the embodiment provided in the present application, within the first display area A, the color filter layer 3 includes a plurality of color resists 31, and each of the color resists 31 corresponds to the position of one of the light-emitting units 21; at the same time, the display panel 100 also includes a plurality of dimming structures 4, and the dimming structure 4 is arranged between two adjacent color resists 31. In this way, the reflectivity of the ambient light can be adjusted by the dimming structure 4, so that when the display panel 100 is in the screen-off state, the reflectivity of the position of the first display area A to the ambient light is adjusted, thereby reducing the difference in reflectivity between the first display area A and other areas, so that the first display area A is not obvious to the human eye, thereby improving the problem of visual difference in the position of the first display area A when the display panel is in the screen-off state.

[0051] In one embodiment, the display panel 100 also includes an encapsulation layer 5, a touch layer 6 and a flat layer 7, wherein the encapsulation layer 5 is disposed on the light-emitting functional layer 2 for encapsulating the light-emitting functional layer 2; the touch layer 6 is disposed on a side of the encapsulation layer 5 away from the array substrate 1; the color filter layer 3 is disposed on a side of the touch layer 6 away from the encapsulation layer 5; and the flat layer 7 is disposed on a side of the color filter layer 3 away from the touch layer 6.

[0052] In the prior art, the display panel 100 has a first display area A and a second display area B located outside the first display area A. Taking the under-screen display technology as an example, the transmittance of the first display area A is greater than the transmittance of the second display area B. The display panel 100 is provided with an infrared sensor, such as a light sensor, a distance sensor, a camera light sensor, etc., at a position corresponding to the first display area A. In combination with the PLP technology, by using the BM layer to block at the position between two adjacent light-emitting units and using the CF layer to filter at the position corresponding to the light-emitting unit, the transmittance of the BM layer to visible light (wavelength range 380-780nm) is close to 0%, and the transmittance to infrared light is generally less than 30%; in the CF layer, the transmittance of the red color resistance to infrared light is greater than 70%, the transmittance of the green color resistance to infrared light is greater than 90%, and the transmittance of the blue color resistance to infrared light is greater than 90%. In order to increase the infrared light transmittance of the first display area A, a light-transmitting opening is usually opened on the BM layer. However, the setting of the light-transmitting opening will also allow more visible light to pass through, thereby increasing the reflectivity of the visible light at the light-transmitting opening. As a result, when the screen is off, a bright spot can be seen by the human eye, that is, there will be a visual difference in the first display area A.

[0053] In some embodiments of the present application, at least in the first display area A, a light-transmitting area is formed between two adjacent color resists 31; the dimming structure 4 is arranged in the light-transmitting area; the setting of the light-transmitting area can improve the transmittance of infrared light at the position of the first display area A; at the same time, the dimming structure 4 is used to adjust the reflectivity of ambient light, so that when the display panel 100 is in the screen-off state, the reflectivity of the first display area A position to ambient light is adjusted, thereby reducing the difference in reflectivity between the first display area A and other areas, so that the first display area A is not obvious to the human eye, thereby improving the problem of visual difference in the position of the first display area A when the display panel is in the screen-off state.

[0054] The present application does not impose any specific restrictions on the structure of the dimming structure 4. The dimming structure 4 can be set as a single-layer color resist pattern, or can be set as a stacked structure of multiple layers of color resist patterns. The thickness of the dimming structure 4 is different, which corresponds to different transmission spectra, thereby having different visible light reflectance and screen-off hue levels, and can be designed according to product requirements.

[0055] It can be known that the infrared light transmittance of the color resist is 68%-99%. Therefore, on the basis of ensuring the infrared light transmittance, part of the visible light transmittance can be reduced. In this way, the reflectivity of the visible light in the light-transmitting area can be reduced, thereby reducing the reflectivity difference between the first display area A and other areas, making the first display area A not obvious to the human eye, thereby improving the problem of visual difference in the first display area A when the screen is off.

[0056] Based on this, the present application does not specifically limit the color of the dimming structure 4. The dimming structure 4 can be set to at least one of red color resistance, green color resistance and blue color resistance. The different colors of the dimming structure 4 correspond to different transmission spectra, thereby having different visible light reflectance and screen-off hue levels, which can be designed according to product requirements.

[0057] Meanwhile, the present application does not impose any specific restrictions on the shape of the dimming structure 4. The dimming structure 4 may be circular, square, polygonal or other irregular shapes, and may be designed according to product requirements.

[0058] See also Figures 1 to 4 In the first embodiment of the present application, the color filter layer 3 also includes a black matrix 32 for spacing the multiple color resists 31, and at least in the first display area A, a photosensitive opening 33 is set on the black matrix 32; the dimming structure 4 is set in the photosensitive opening 33; wherein the photosensitive opening 33 forms the light-transmitting area; the dimming structure 4 includes a single-layer color resist pattern, and the color resist pattern is set in the photosensitive opening 33.

[0059] In the first embodiment, the color filter layer 3 also includes a black matrix 32, and the black matrix 32 is separated by a plurality of the color resists 31; the black matrix 32 does not transmit visible light, and its transmittance to infrared light is generally less than 30%; in the first display area A, by setting the photosensitive opening 33 on the black matrix 32, the transmittance of infrared light in the first display area A can be improved; the color resist pattern is set in the photosensitive opening 33, and the transmittance of infrared light by the color resist pattern is 68%-99%. In this way, while ensuring the transmittance of infrared light, part of the visible light transmission can be reduced, and the reflectivity of visible light at the photosensitive opening 33 can be reduced, thereby reducing the reflectivity difference between the first display area A and other areas, so that the first display area A is not obvious to the human eye, thereby improving the problem of visual difference in the first display area A when the screen is off.

[0060] The present application does not impose any specific limitation on the thickness of the dimming structure 4 . The dimming structure 4 includes a single-layer color resist pattern. The thickness of the color resist pattern is set to 1 μm to 4.5 μm and can be designed according to product requirements.

[0061] As mentioned above, the dimming structure 4 includes a single-layer color resist pattern. Figure 5 When the dimming structure 4 is set to red color resistance, the thickness of the dimming structure 4 is set to 3μm, the dimming structure 4 transmits red visible light, and the infrared light transmittance of the dimming structure 4 is 79%; when the dimming structure 4 is set to green color resistance, the thickness of the dimming structure 4 is set to 3μm, the dimming structure 4 transmits green visible light, and the infrared light transmittance of the dimming structure 4 is 98%; when the dimming structure 4 is set to blue color resistance, the thickness of the dimming structure 4 is set to 3μm, the dimming structure 4 transmits blue visible light, and the infrared light transmittance of the dimming structure 4 is 95%.

[0062] Preferably, the color of the dimming structure 4 is set to blue or green, so that on the basis of ensuring the transmittance of infrared light, part of the visible light transmission can be reduced, and the reflectivity of visible light at the photosensitive opening 33 can be reduced, thereby reducing the reflectivity difference between the first display area A and other areas, making the first display area A not obvious to the human eye, thereby improving the problem of visual difference in the first display area A when the screen is off.

[0063] Furthermore, among the plurality of color resists 31 adjacent to the photosensitive opening 33, one of the color resists 31 extends toward the photosensitive opening 33 and forms a first extension portion 34 filling the photosensitive opening 33; the dimming structure 4 includes the first extension portion 34. For example, "the dimming structure 4 is set as a blue color resist, and the thickness of the dimming structure 4 is set to 3 μm", please refer to Figure 1 and Figure 2 Among the multiple color resists 31, a first color resist 311 adjacent to the photosensitive opening 33 is included. The first color resist 311 is set as a blue color resist. The first color resist 311 extends toward the photosensitive opening 33 and forms a first extension portion 34 filling the photosensitive opening 33. The first extension portion 34 fills the photosensitive opening 33 and covers the periphery of the photosensitive opening 33, thereby forming the dimming structure 4.

[0064] See also Figure 6 and Figure 7In the second embodiment of the present application, the color filter layer 3 also includes a black matrix 32 for spacing the multiple color resists 31, and at least in the first display area A, a photosensitive opening 33 is set on the black matrix 32; the dimming structure 4 is set in the photosensitive opening 33; wherein the photosensitive opening 33 forms the light-transmitting area; in the thickness direction F1 of the display panel 100, the dimming structure 4 includes at least two layers of color resist patterns stacked together, the two layers of the color resist patterns are stacked in the photosensitive opening 33, and the two layers of the color resist patterns have different colors.

[0065] In the second embodiment, the difference from the first embodiment is that the dimming structure 4 includes at least two layers of color resist patterns stacked in layers. The dimming structure 4 has an infrared light transmittance greater than 70%, so that on the basis of ensuring infrared light transmittance, part of the visible light transmission can be reduced, and the reflectivity of the visible light at the photosensitive opening 33 can be reduced, thereby reducing the reflectivity difference between the first display area A and other areas, making the first display area A not obvious to the human eye, thereby improving the problem of visual difference in the first display area A when the screen is off.

[0066] The present application does not impose any specific limitation on the thickness of the color resist pattern. The thickness of a single layer of the color resist pattern is set to 1 μm to 4.5 μm, which can be designed according to product requirements.

[0067] As described above, in one embodiment, the dimming structure 4 includes two stacked color resist patterns, the two color resist patterns include a red color resist pattern and a blue color resist pattern, the thickness of the red color resist pattern is set to 1.5 μm, the thickness of the blue color resist pattern is set to 1.5 μm, the transmittance of the dimming structure 4 to visible light is less than 5%, and the transmittance of the dimming structure 4 to infrared light is 84%.

[0068] In other embodiments, see Figure 6 and Figure 7 The dimming structure 4 includes three layers of color resist patterns stacked together, the three layers of the color resist patterns include a red color resist pattern, a green color resist pattern and a blue color resist pattern, the thickness of the red color resist pattern is set to 1μm, the thickness of the green color resist pattern is set to 1μm, the thickness of the blue color resist pattern is set to 1μm, the transmittance of the dimming structure 4 to visible light is less than 5%, and the transmittance of the dimming structure 4 to infrared light is 91%.

[0069] Furthermore, among the multiple color resists 31 adjacent to the photosensitive opening 33, at least two color resists 31 with different colors extend toward the photosensitive opening 33 respectively and form two second extension portions 35 correspondingly. In the thickness direction F1 of the display panel 100, the two second extension portions 35 are stacked and fill the photosensitive opening 33; wherein the dimming structure 4 includes two second extension portions 35 stacked.

[0070] Take "the dimming structure 4 includes three layers of color resist patterns stacked together, the three layers of color resist patterns including a red color resist pattern, a green color resist pattern and a blue color resist pattern" as an example for explanation. Figure 6 and Figure 7 The plurality of color resists 31 include a first color resist 311, a second color resist 312, and a third color resist 313 adjacent to the photosensitive opening 33, wherein the first color resist 311 is set as a blue color resist, the second color resist 312 is set as a green color resist, and the third color resist 313 is set as a red color resist; the first color resist 311 extends toward the photosensitive opening 33 and forms a first layer of second extension portion 35, the second extension portion 35 fills the photosensitive opening 33 and covers the periphery of the photosensitive opening 33; the second color resist 312 extends toward the photosensitive opening 33 and forms a second layer of second extension portion 35; the third color resist 313 extends toward the photosensitive opening 33 and forms a third layer of second extension portion 35, and the three layers of second extension portions 35 stacked together form the dimming structure 4.

[0071] In the first embodiment and the second embodiment, the present application does not limit the size and number of the photosensitive openings 33 , and the size and number of the photosensitive openings 33 may be designed according to the requirements of the specific infrared sensor for the infrared light transmittance.

[0072] The present application does not limit the distance between the edge of the photosensitive opening 33 and the adjacent edge of the color resist 31. In one embodiment, the distance H between the edge of the photosensitive opening 33 and the adjacent edge of the color resist 31 is greater than 5 μm.

[0073] It can be known that, in the first embodiment and the second embodiment, the color filter layer 3 also includes a black matrix 32, and the photosensitive openings 33 are arranged on the black matrix 32; although the provision of the photosensitive openings 33 can increase the transmittance of infrared light; however, part of the black matrix 32 will still block infrared light.

[0074] In order to further increase the infrared light transmittance of the first display area A, at least at the location of the first display area A, the black matrix 32 is removed from the color filter layer 3 .

[0075] See also Figure 8 and Fig. 9In the third embodiment, at least in the first display area A, the dimming structure 4 is arranged between two adjacent color resists 31; in the thickness direction F1 of the display panel 100, the dimming structure 4 includes three layers of stacked color resist patterns 41; the three layers of the color resist patterns 41 are colorful and have different colors.

[0077] On the touch layer 6 , a single layer of red color resist, green color resist and blue color resist forms the color resist 31 ; and a stacked layer of red color resist, green color resist and blue color resist forms the dimming structure 4 .

[0078] Although in the third embodiment, the black matrix 32 is eliminated from the color filter layer 3, the dimming structure 4 is provided between two adjacent color resists 31 at a position between two adjacent light-emitting units 21, and the dimming structure 4 includes stacked red color resists, green color resists, and blue color resists. Therefore, the transmittance of the dimming structure 4 to visible light is less than 5%, which is equivalent to the black matrix 32 in the first and second embodiments. However, the transmittance of the dimming structure 4 to infrared light is greater than 70%, forming the light-transmitting area, which has a greater infrared light transmittance than the black matrix 32 in the first and second embodiments.

[0079] See also Fig.11 and Fig.12 In the fourth embodiment, at least in the first display area A, the dimming structure 4 is arranged between two adjacent color resists 31; in the thickness direction F1 of the display panel 100, the dimming structure 4 includes three layers of stacked color resist patterns 41; the three layers of the color resist patterns 41 are colorful and have different colors.

[0080] In the fourth embodiment, see Fig.12 and Fig.13 , a blue color resist pattern 413 is arranged on the touch layer 6, and the blue color resist pattern 413 is patterned using a blue mask 83, and a fourth through hole 45 is formed on the blue color resist pattern 413, and the fourth through hole 45 corresponds to the position of a part of the light-emitting unit 21; a red color resist pattern 411 is arranged on the blue color resist pattern 413, and the red color resist pattern 411 is patterned using a red mask 81, and a fifth through hole 46 is formed on the red color resist pattern 411, and the fifth through hole 46 corresponds to the position of a part of the light-emitting unit 21; a green color resist pattern 412 is arranged on the red color resist pattern 411, and the green color resist pattern 412 is patterned using a green mask 82, and a sixth through hole 47 is formed on the green color resist pattern 412.

[0081] On the touch layer 6 , a single layer of red color resist, green color resist and blue color resist forms the color resist 31 ; and a stacked layer of red color resist, green color resist and blue color resist forms the dimming structure 4 .

[0082] Although in the fourth embodiment, the black matrix 32 is eliminated from the color filter layer 3, the dimming structure 4 is provided between the two adjacent color resists 31 at the position corresponding to the position between the two adjacent light-emitting units. The dimming structure 4 includes a stacked red color resist, a green color resist and a blue color resist. Therefore, the transmittance of the dimming structure 4 to visible light is less than 5%, which is equivalent to the black matrix 32 in the first and second embodiments. However, the transmittance of the dimming structure 4 to infrared light is greater than 70%, which has a greater infrared light transmittance than the black matrix 32 in the first and second embodiments.

[0083] It should be noted that, in another embodiment, the green color resist pattern 412 may be manufactured first, and then the blue color resist pattern 413 and the red color resist pattern 411 may be manufactured in sequence.

[0084] In the third embodiment and the fourth embodiment, the present application does not impose any specific limitation on the sizes of the color resist 31 and the dimming structure 4 , and they can be designed according to product requirements.

[0085] The third embodiment is used as an example for description. Fig. 9 and Fig.10, the size of the first through hole 42 corresponding to the blue color resist 31 on the red mask 81 is B-CD, and the size of the first through hole 42 corresponding to the green color resist 31 is G-CD; the size of the second through hole 43 corresponding to the blue color resist 31 on the green mask 82 is B-CD+X, and the size of the second through hole 43 corresponding to the red color resist 31 is R-CD; the size of the third through hole 44 corresponding to the green color resist 31 on the blue mask 83 is G-CD+X, and the size of the third through hole 44 corresponding to the red color resist 31 is R-CD+X. X refers to the safety distance to ensure that the next process will not interfere with the opening size of the previous process.

[0086] The calculation of the X value is related to the alignment film layer, size tolerance and position tolerance of the color resist 31. For example, the position tolerance OLR of the red color resist 31 is set to ±1μm, the size tolerance CDR of the red color resist 31 is set to ±1.2μm, the position tolerance OLG of the green color resist 31 is set to ±1μm, and the size tolerance CDG of the green color resist 31 is set to ±1.4μm, then according to the calculation formula = 1.69μm.

[0087] See also Figure 3 and Figure 4 In the above-mentioned first embodiment, second embodiment, third embodiment and fourth embodiment, in the second display area B, the dimming structure 4 is disposed between two adjacent color resists 31 .

[0088] See also Figures 14 to 17 In some other embodiments of the present application, the color filter layer 3 also includes a black matrix 32 for spacing the multiple color resists 31; the multiple dimming structures 4 are arranged on a side of the black matrix 32 away from the array substrate 1.

[0089] The difference from the above embodiment is that: Figures 14 to 17 In the figure, the photosensitive opening 33 is not provided on the black matrix 32; it can be known that, in the color filter layer 3, the black matrix 32 is utilized to prevent the display panel 100 from leaking light, and the light reflectivity of the display panel 100 is increased, and the color resist 31 is provided at the position corresponding to the sub-pixel area 1a; in the screen-off state, on the color filter layer 3, the positions corresponding to the black matrix 32 and the color resist 31 have different reflectivities to ambient light, so that there will be visual differences in the display panel at the IR hole position.

[0090] In the embodiment of the present application, the dimming structure 4 is arranged on the side of the black matrix 32 away from the array substrate 1; by setting the dimming structure 4, the coverage area of ​​the color photoresist is increased, so that when the display panel 100 is in the screen-off state, the reflectivity of the first display area A position to the ambient light is adjusted, thereby reducing the reflectivity difference between the first display area A and other areas, making the first display area A not obvious to the human eye, thereby improving the problem of visual difference in the first display area A position when the display panel is in the screen-off state.

[0091] As mentioned above, the dimming structure 4 can be set as a single-layer color resist pattern, or can be set as a multi-layer color resist pattern stacking structure.

[0092] In one embodiment, see Fig.14 The dimming structure 4 includes a single-layer color resist pattern, and the color resist pattern has the same color as one of the adjacent color resists 31; that is, the dimming structure 4 can be set to one of a red color resist pattern, a green color resist pattern or a blue color resist pattern.

[0093] In one embodiment, see Fig.15 In the thickness direction F1 of the display panel 100, the dimming structure 4 includes three layers of color resist patterns stacked together, and the colors of the three layers of color resist patterns are different; that is, the dimming structure 4 includes a red color resist pattern, a green color resist pattern and a blue color resist pattern stacked together; by setting the three layers of the color resist patterns stacked together, on the one hand, the hue of the first display area A in the screen-off state can be adjusted; on the other hand, the light reflectivity can be reduced, the light reflectivity of each part of the first display area A in the screen-off state can be balanced, and the problem of local visual differences in the first display area A in the screen-off state can be improved.

[0094] See also Fig.15 The plurality of color resists 31 include a first color resist 311, a second color resist 312 and a third color resist 313, wherein the first color resist 311 is set to be a blue color resist, the second color resist 312 is set to be a green color resist, and the third color resist 313 is set to be a red color resist; the peripheral side of the first color resist 311 extends to form a first color resist pattern 36, and the first color resist pattern 36 covers the black matrix 32; the peripheral side of the second color resist 312 extends to form a second color resist pattern 37, and the second color resist pattern 37 covers the first color resist pattern 36; the peripheral side of the third color resist 313 extends to form a third color resist pattern 38, and the third color resist pattern 38 covers the second color resist pattern 37, and the first color resist pattern 36, the second color resist pattern 37 and the third color resist pattern 38 are stacked to form the dimming structure 4.

[0095] See also Fig.16 In the fifth embodiment of the present application, the dimming structure 4 and the color resist 31 adjacent thereto are arranged at intervals; the color resist 31 is arranged on the black matrix 32, and the color resists of the same color are usually made using the same mask, so that the dimming structure 4 can be made synchronously using a mask of a color resist. In this way, dimming structures 4 of different colors can be formed on the black matrix 32 using masks of different colors; at the same time, the area of ​​the dimming structure 4 can be adjusted by adjusting the size of the pattern on the mask, thereby adjusting the hue correction amplitude.

[0096] See also Fig.17 In the sixth embodiment of the present application, the plurality of color resists 31 adjacent to the dimming structure 4 include a first color resist 311 having the same color as the dimming structure 4 , and the first color resist 311 partially overlaps with the dimming structure 4 .

[0097] In other embodiments of the present application, in order to ensure that the light reflectivity and screen-off color of the first display area A and the second display area B are consistent, in the second display area B, the dimming structure 4 is located between two adjacent color resists 31 and is arranged on the side of the black matrix 32 away from the array substrate 1.

[0098] That is to say, the dimming structures 4 in the first embodiment to the sixth embodiment can all be disposed in the second display area B of the display panel.
