Description

Technical Field

[0001] This disclosure relates to the field of display technology, and more particularly to a display panel and display device. Background Technology

[0002] From the CRT (Cathode Ray Tube) era to the LCD (Liquid Crystal Display) era, and now to the OLED (Organic Light Source) era... In the era of organic light-emitting diodes (OLEDs) and LED displays, the display industry has undergone rapid development over the past few decades. The display industry is now closely related to our lives, from traditional mobile phones, tablets, televisions, and PCs to today's smart wearable devices, VR, automotive displays, and other electronic devices, all of which rely on display technology.

[0003] With the development of display technology, users have increasingly higher demands for the diverse functions of display products. For example, fingerprint recognition and ambient light recognition have become essential features of display products. However, the implementation of these functions can easily cause visual differences in display products under conditions such as when the screen is off or under strong light.

[0004] Therefore, how to reduce the visual effect difference of display products under off-screen or strong light illumination has become one of the technical problems that urgently need to be solved by those skilled in the art. Summary of the Invention

[0005] To address the aforementioned technical problems, this disclosure provides a display panel and display device for reducing the visual effect difference of display products under off-screen or strong light illumination.

[0006] In a first aspect, this disclosure provides a display panel, including: a pixel aperture area and a photosensitive area, wherein the pixel aperture area is provided with a light-emitting element and the photosensitive area is provided with a light-transmitting hole; The display panel includes a light filter layer located on one side of the light-emitting surface of the light-emitting element. The light filter layer includes a first color resist, which overlaps with the light-emitting element. The filter layer includes a second color resist, which at least partially overlaps with at least one of the light-transmitting holes.

[0007] Based on the same inventive concept, this disclosure also provides a display device, including the display panel as described above.

[0008] Compared with the prior art, the technical solution provided in this disclosure has the following advantages: This disclosure provides a display panel and display device, comprising: a pixel aperture area and a photosensitive area. The pixel aperture area is provided with a light-emitting element, and the photosensitive area is provided with a light-transmitting hole. The display panel includes a filter layer located on one side of the light-emitting surface of the light-emitting element. The filter layer includes a first color resist that overlaps with the light-emitting element. The filter layer also includes a second color resist that at least partially overlaps with at least one light-transmitting hole. By providing a second color resist in the vertical direction of the light-transmitting hole, and by having the second color resist at least partially overlap with at least one light-transmitting hole, this disclosure can absorb ambient light through the second color resist overlapping with the light-transmitting hole, thereby reducing the amount of reflected light from the light-transmitting hole and thus reducing the reflectivity of the light-transmitting hole. This reduces the difference in reflectivity between the photosensitive area and the pixel aperture area when the display panel is off or under strong light, achieving a visual experience close to "hole-free". Furthermore, the second color resist is positioned on the side of the light-transmitting hole facing the light-emitting surface of the display panel. This can visually alter the hue of the light-transmitting hole, reducing the hue difference between the photosensitive area and the pixel opening area, and improving the uniformity of the display panel. In the manufacturing process, the first and second color resists can be produced using the same process, eliminating the need for additional steps, simplifying the manufacturing process, and avoiding additional costs.

Detailed Implementation

[0012] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0013] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0014] Traditional under-display optoelectronic technology suffers from inconsistencies in the reflective properties of the pixel aperture area and the photosensitive area due to differences in structure, materials, and color. When the screen is off or under strong light, the photosensitive area appears brighter or darker due to these differences in reflectivity, creating visible "spots" or "holes" that negatively impact the user's visual experience.

[0015] To address the aforementioned issues, this disclosure provides a display panel for reducing visual differences in display products. Figure 1 The figure shown is a plan view of a display panel provided in an embodiment of this disclosure. Figure 2 for Figure 1 A planar schematic diagram of the central photosensitive area. Figure 3 for Figure 2 Please refer to the schematic diagram of a cross-section along B-B'. Figures 1 to 3This disclosure provides a display panel 100, including: a pixel aperture area A2 and a photosensitive area A1, wherein the pixel aperture area A2 is provided with a light-emitting element D, and the photosensitive area A1 is provided with a light-transmitting hole K; please refer to Figure 3 The display panel 100 includes a light filter layer 10 located on one side of the light-emitting surface of the light-emitting element D. The light filter layer 10 includes a first color resist 11, which overlaps with the light-emitting element D. The light filter layer 10 also includes a second color resist 12, which at least partially overlaps with at least one light-transmitting hole K.

[0016] Specifically, along a direction parallel to the plane of the display panel 100, the display panel 100 includes a pixel opening area A2 and a photosensitive area A1, wherein the pixel opening area A2 is used to house the light-emitting element D. Figure 2 The arrangement of the light-emitting elements D in the display panel 100 is for illustrative purposes only, and this disclosure does not limit the number, shape, or arrangement of the light-emitting elements D in the display panel 100.

[0017] This embodiment also illustrates the driving layer, light-emitting layer, etc. on the display panel 100. Please refer to [link / reference]. Figure 3 In one optional embodiment provided in this disclosure, the display panel 100 includes a substrate 00 and a driving layer 40, a sensing layer 30, a light-emitting layer 20, and a filter layer 10 disposed on one side of the substrate 00. The sensing layer 30 is located between the driving layer 40 and the light-emitting layer 20, and the driving layer 40 is located on the side of the sensing layer 30 facing the substrate 00. The filter layer 10 is located on the side of the light-emitting layer 20 away from the substrate 00. The light-emitting layer 20 includes a light-emitting element D. The filter layer 10 includes a light-shielding matrix BM and a plurality of openings defined by the light-shielding matrix BM. A first color resist 11 is formed on some of the openings for color display of the display panel 100, and some openings are used to form light-transmitting holes K for light intake of the photosensitive device 01. It should be noted that, in addition to having openings on the filter layer 10, the light-transmitting hole K also needs to have openings on the pixel definition layer. In order to increase the amount of light transmitted to the photosensitive device 01, an opening corresponding to the light-transmitting hole K can also be provided on the pixel definition layer. For the sake of simplicity in the illustration, Figure 3 The pixel definition layer is not shown. The photosensitive device 01 may be a fingerprint recognition unit or an ambient light sensing unit, etc., and this disclosure does not specifically limit the type of the photosensitive device 01. Along the direction perpendicular to the substrate 00, the light-transmitting hole K overlaps with the photosensitive device 01; at least one light-transmitting hole K is at least partially covered by the second color resist 12.

[0018] Optionally, the driving layer 40 includes a driving circuit, comprising a pixel driving circuit P0 for driving the light-emitting element D and a photosensitive driving circuit P1 for driving the photosensitive device 01. The pixel driving circuit P0 is connected to the light-emitting element D to drive it to emit light, and the photosensitive driving circuit P1 is connected to the photosensitive device 01 to receive the sensing signal. Optionally, the photosensitive device 01 includes a photodiode, which can be fabricated using a thin-film structure in related technologies. When there is no light, the photodiode is in a forward bias state with a very small current. When light shines on the photosensitive layer of the photodiode, photons excite electrons and holes in the semiconductor of the photodiode to migrate, forming a current. The current generated in the photosensitive device 01 is output to the photosensitive driving circuit P1, thereby realizing the light sensing function. Optionally, the driving layer 40 includes an oxide thin-film transistor and an amorphous silicon thin-film transistor. Figure 3 This diagram only illustrates one connection relationship between the transistors in the driving layer 40 and the photosensitive device 01 and the light-emitting element D, and does not limit the types of transistors actually connected to the photosensitive device 01 and the light-emitting element D. The following will use... Figure 3 The specific structure of the driving layer 40 will be described using an example. Optionally, the driving layer 40 includes an active layer Poly, a first metal layer M1, a capacitor metal layer, a second metal layer M2, and a third metal layer M3 disposed on the substrate 00. The first metal layer M1 can be, for example, a gate metal layer. The source and drain electrodes of the transistor can be located in the second metal layer M2. The active layer Poly includes a source region and a drain region. The source electrode of the transistor is electrically connected to the source region of the semiconductor layer Poly through a contact hole, and the drain electrode is electrically connected to the drain region of the active layer Poly through a contact hole. The third metal layer M3 can be considered as a wiring layer, used to electrically connect the corresponding transistor to the photosensitive device 01 or the light-emitting element D. It should be noted that... Figure 3 The film structure shown is for illustrative purposes only and does not limit the actual film structure of the display panel 100.

[0019] The photosensitive area A1 is provided with a light-transmitting hole K. The light-transmitting hole K is parallel to the plane of the display panel 100 and does not overlap with the light-emitting element D. The light-transmitting hole K is used to increase the brightness of the display panel 100 or to provide ambient light for the camera or photosensitive device 01 inside the display panel 100. Please refer to... Figure 3 The display panel 100 includes a light filter layer 10. Along a direction perpendicular to the plane of the display panel 100, the light filter layer 10 is located on one side of the light-emitting surface of the light-emitting element D. The light filter layer 10 includes a first color resist 11. The first color resist 11 overlaps with the light-emitting element D in a direction perpendicular to the plane of the display panel 100. The first color resist 11 can be a blue color resist, a red color resist, or a green color resist. It is used to form light of a specific color emitted by the light-emitting element D, thereby realizing the color display of the display panel 100.

[0020] In this embodiment, the filter layer 10 includes a second color resist 12. Along a direction perpendicular to the plane of the display panel 100, the second color resist 12 at least partially overlaps with at least one light-transmitting hole K. That is, a first color resist 11 and a second color resist 12 are simultaneously disposed in the filter layer 10 on the light-emitting surface of the light-emitting element D. The first color resist 11 overlaps with the light-emitting element D in the thickness direction of the display panel 100, and the second color resist 12 overlaps with at least one light-transmitting hole K in the thickness direction of the display panel 100. The first color resist 11 is used for the color display of the light-emitting element D, and the light-transmitting hole K allows external light to enter, improving the transmittance of the display panel 100 or providing ambient light for the photosensitive device 01.

[0021] This embodiment illustrates a scheme where a second color resist 12 is introduced on the side of the light-transmitting hole K of the OLED display panel facing the light-emitting surface of the display panel 100 when the display panel 100 provided in this embodiment is an OLED display panel. Compared to related technologies where only the light-transmitting hole K is provided for the light intake of the photosensitive device 01, this embodiment provides the second color resist 12 in the vertical direction of the light-transmitting hole K, and the second color resist 12 at least partially overlaps with at least one light-transmitting hole K. The light-shielding matrix BM in the filter layer 10 and the second color resist 12 have the function of absorbing light. When ambient light shines on the display panel 100, the light shining on the light-shielding matrix BM can be absorbed by the light-shielding matrix BM, and the light shining on the second color resist 12 can be at least partially absorbed by the second color resist 12, thereby reducing the light reflection of the light-transmitting hole K, reducing the difference in reflectivity between the photosensitive area A1 and the pixel opening area A2 of the display panel 100 in the off state or under strong light, and improving the user experience. In addition, the setting of the second color resist 12 can also change the hue of the light-transmitting hole K, thereby changing the hue of the photosensitive area A1, making the hue of the photosensitive area A1 as close as possible to the hue of the pixel opening area A2, so that the display panel 100 can not be seen from the appearance, improving the uniformity of the appearance and facilitating the realization of full-screen display.

[0022] In actual production, the first color resist 11 and the second color resist 12 can be manufactured in the same process, without the need to introduce different manufacturing processes for the first color resist 11 and the second color resist 12. This simplifies the manufacturing process of the display panel when the second color resist 12 is introduced into the display panel, improves production efficiency, and does not increase costs.

[0023] Figure 1The illustrated embodiment only uses a rectangular display panel 100 as an example to illustrate the display panel 100 of this disclosure, and does not limit the specific structure of the display panel 100 of this disclosure. In some other embodiments of this disclosure, the shape of the display panel 100 may also be a rounded rectangle, a circle, an ellipse, or other structures including curved edges, and this disclosure does not specifically limit it. Figure 1 The illustration only shows one relative position of the pixel aperture area A2 and the photosensitive area A1 on the display panel 100. In other embodiments of this disclosure, the relative positional relationship between the pixel aperture area A2 and the photosensitive area A1 can also be of other types, and the shape of the photosensitive area A1 can also be set according to the actual situation. Figure 1 The rectangle shown is for illustrative purposes only. For example, the photosensitive area A1 can also be set as a circle, square, polygon, etc. In addition, the size of the photosensitive area A1 can also be flexibly set according to actual needs.

[0024] Optionally, the display panel 100 provided in this embodiment can be a display panel using organic light-emitting diode display technology, i.e., OLED (Organic Light Diode). The basic structure of an OLED display panel includes an anode, an emissive layer, and a cathode. When a suitable voltage is supplied, holes in the anode and electrons in the cathode combine in the emissive material layer to produce light. Of course, in some other embodiments of the present invention, the display panel 100 may also be a display panel employing inorganic light-emitting diode display technology, such as a Micro LED display panel, or a Mini LED display panel, etc.

[0025] Figure 4 As shown Figure 1 Please refer to another planar schematic diagram of the central photosensitive area. Figure 4 This disclosure provides a display panel 100, wherein the light-transmitting hole K includes a first light-transmitting hole K1 and a second light-transmitting hole K2. Along the direction perpendicular to the light-emitting surface of the display panel 100, the overlap area of ​​the second color resist 12 with the first light-transmitting hole K1 and the second light-transmitting hole K2 is different.

[0026] Specifically, along a direction perpendicular to the light-emitting surface of the display panel 100, one second color resist 12 at least partially overlaps with the first light-transmitting hole K1, and another second color resist 12 at least partially overlaps with the second light-transmitting hole K2. The overlapping area of ​​the second color resist 12 with the first light-transmitting hole K1 is a first area, and the overlapping area of ​​the second color resist 12 with the second light-transmitting hole K2 is a second area. The first area and the second area are different. By setting the second color resist 12 to have different overlapping areas with the first light-transmitting hole K1 and the second light-transmitting hole K2, the first area formed by the overlap of the second color resist 12 with the first light-transmitting hole K1 absorbs a first amount of light, and the second area formed by the overlap of the second color resist 12 with the second light-transmitting hole K2 absorbs a second amount of light. The first amount and the second amount are different, meaning that different overlapping areas absorb different amounts of reflected light. While meeting the light transmission requirements, it is possible to achieve a differentiated design of the reflectivity of different light-transmitting holes K in the photosensitive area A1. This can also reduce the difference in reflectivity between the photosensitive area A1 and the display area, and improve the display uniformity of the display panel 100 in the off state.

[0027] Figure 5 As shown Figure 1 Please refer to another planar schematic diagram of the central photosensitive area. Figure 5 This disclosure provides a display panel 100 in which a second color resist 12 partially overlaps with a first light-transmitting hole K1 along a direction perpendicular to the light-emitting surface of the display panel 100, and the second color resist 12 covers the second light-transmitting hole K2.

[0028] In one optional embodiment provided in this disclosure, along a direction perpendicular to the light-emitting surface of the display panel 100, a second color resist 12 partially overlaps with the first light-transmitting hole K1, and the overlapping area of ​​the second color resist 12 and the first light-transmitting hole K1 is a first area, which is smaller than the area of ​​the first light-transmitting hole K1; another second color resist 12 covers the second light-transmitting hole K2, and the overlapping area of ​​the second color resist 12 and the second light-transmitting hole K2 is a second area, which is greater than or equal to the area of ​​the second light-transmitting hole K2. Because the second color resist 12 partially overlaps with the first light-transmitting hole K1, external light can enter the interior of the display panel 100 through the first light-transmitting hole K1, ensuring sufficient external light to enter, which is beneficial for the normal use of the under-display fingerprint recognition unit or the ambient light sensor. Furthermore, because the second color resist 12 partially overlaps with the first light-transmitting hole K1, the second color resist 12 can absorb at least a portion of the light illuminating the second color resist 12, thereby reducing light reflection from the first light-transmitting hole K1, effectively reducing the amount of reflected light emitted from the photosensitive area A1, and reducing visual interference. Since the second color resist 12 covers the second light-transmitting aperture K2, it allows ambient light of the same color as the resist to pass through while absorbing light of a different color. In this case, the photosensitive device 01 can be configured as a sensor adapted to the type of light transmitted through the second light-transmitting aperture K2, enabling the normal operation of a specific type of sensor. The second color resist 12 covering the second light-transmitting aperture K2 absorbs most of the light incident on it, further reducing light reflection from the aperture and decreasing the reflectivity difference between the photosensitive area A1 and the pixel opening area A2.

[0029] Optionally, the light-shielding matrix in the filter layer 10 can also be fabricated using color resists. For example, the light-shielding matrix can be fabricated using two different colors of color resists. The light-shielding matrix, the first color resist 11, and the second color resist 12 are fabricated in the same process. The difference is that the first color resist 11 is a single color and covers one side of the light-emitting surface of the light-emitting element to achieve color display of different light-emitting elements; the second color resist 12 is also a single color, and in the direction of the light-emitting surface of the display panel 100, the second color resist 12 at least partially overlaps with at least one light-transmitting hole K to reduce the reflectivity of the light-transmitting hole K. That is, the second color resist 12 can be fabricated simultaneously with the light-shielding matrix using one of the colors of color resists used to fabricate the light-shielding matrix, completing the fabrication of the second color resist 12 without adding any new processes or steps, thus reducing the manufacturing process. The above is merely an example; it is understood that other colors of color resists different from those in the light-shielding matrix can also be used to fabricate the second color resist 12, and this disclosure does not limit this.

[0030] Thus, by setting the first light-transmitting hole K1 in the photosensitive area A1 to partially overlap with the second color resist 12 in the thickness H direction of the display panel 100, and setting the second light-transmitting hole K2 to completely overlap with the second color resist 12 in the thickness H direction of the display panel 100, the reflectivity of the photosensitive area A1 can be further reduced, thereby further reducing the difference in reflectivity between the photosensitive area A1 and the display area in the screen-off state, which is beneficial to improving the uniformity of the display surface.

[0031] Please refer to Figure 4 and Figure 5 This disclosure provides a display panel 100, wherein the second color resist 12 corresponding to the first light-transmitting hole K1 has the same color as the second color resist 12 corresponding to the second light-transmitting hole K2.

[0032] Optionally, the second color resist 12 corresponding to the first light-transmitting hole K1 and the second color resist 12 corresponding to the second light-transmitting hole K2 are both red color resists; or, the second color resist 12 corresponding to the first light-transmitting hole K1 and the second color resist 12 corresponding to the second light-transmitting hole K2 are both blue color resists; or, the second color resist 12 corresponding to the first light-transmitting hole K1 and the second color resist 12 corresponding to the second light-transmitting hole K2 are both green color resists.

[0033] In this embodiment, along a direction perpendicular to the plane of the display panel 100, the second color resist 12 partially overlaps with the first light-transmitting hole K1, and the second color resist 12 covers the second light-transmitting hole K2. The second color resist 12 corresponding to the first light-transmitting hole K1 and the second color resist 12 corresponding to the second light-transmitting hole K2 have the same color. In the manufacturing process, assuming that the first light-transmitting hole K1 and the second light-transmitting hole K2 correspond to different colors of color resist, manufacturing two different colors of second color resist 12 would require two different sets of materials, photomasks, and process steps, significantly increasing production complexity and cost. In this embodiment, since the second color resist 12 corresponding to the first light-transmitting hole K1 and the second color resist 12 corresponding to the second light-transmitting hole K2 have the same color, they can be manufactured using the same material and the same color, greatly simplifying the process. Color resists of the same color made with the same color and material will have consistent physical and chemical properties, helping to improve product yield and reducing the risks of adverse reactions that may occur during manufacturing due to different materials, or delamination and peeling that may occur during long-term use. Thus, this embodiment differentiates the overlapping areas of the second color resist 12 corresponding to the first light-transmitting hole K1 and the second light-transmitting hole K2, and sets the colors of the second color resist 12 corresponding to the first light-transmitting hole K1 and the second color resist 12 corresponding to the second light-transmitting hole K2 to be the same. This can reduce the reflectivity of the photosensitive area A1, and by using the same color of the second color resist 12, the manufacturing process can be greatly simplified, which is conducive to reducing costs and improving the feasibility of large-scale mass production.

[0034] Please continue to refer to this. Figure 4 and Figure 5 This disclosure provides a display panel 100, wherein the second color resist 12 corresponding to the first light-transmitting hole K1 has a different color than the second color resist 12 corresponding to the second light-transmitting hole K2.

[0035] In one optional embodiment provided in this disclosure, along a direction perpendicular to the plane of the display panel 100, the second color resist 12 partially overlaps with the first light-transmitting hole K1, and the second color resist 12 covers the second light-transmitting hole K2. The second color resist 12 corresponding to the first light-transmitting hole K1 has a different color than the second color resist 12 corresponding to the second light-transmitting hole K2. The second color resist 12 is one of blue, red, or green color resists. For example, the second color resist 12 corresponding to the first light-transmitting hole K1 is blue, and the second color resist 12 corresponding to the second light-transmitting hole K2 is red; or, the second color resist 12 corresponding to the first light-transmitting hole K1 is green, and the second color resist 12 corresponding to the second light-transmitting hole K2 is blue; or, the second color resist 12 corresponding to the first light-transmitting hole K1 is red, and the second color resist 12 corresponding to the second light-transmitting hole K2 is green, and so on. They are not listed one by one here. It is only necessary to set the colors of the second color resist 12 corresponding to the first light-transmitting hole K1 and the second color resist 12 corresponding to the second light-transmitting hole K2 to be different.

[0036] By using a second color resist 12 of a different color to cover the second light-transmitting hole K2 or partially block the first light-transmitting hole K1, the reflectivity of the light-transmitting hole K can be reduced, and the hue of different light-transmitting holes K can be further changed, thereby changing the hue of the photosensitive area A1. The second color resist 12 is one of blue, red, or green color resist. That is, by setting the second color resist 12 corresponding to different light-transmitting holes K to the color type of the first color resist 11 corresponding to the light-emitting element D, the hue of the light-transmitting hole K can be close to the hue of the light-emitting element D in the pixel opening area A2, which is beneficial to improving the uniformity of the display panel 100 and reducing the hue difference between the photosensitive area A1 and the pixel opening area A2. Thus, by differentiating the overlapping areas of the second color resists 12 corresponding to the first light-transmitting hole K1 and the second light-transmitting hole K2, and further setting the colors of the second color resists 12 corresponding to the first light-transmitting hole K1 and the second color resists 12 corresponding to the second light-transmitting hole K2 to be different, it is possible to reduce the reflectivity of the photosensitive area A1 while making the hue of the light-transmitting hole K in the photosensitive area A1 closer to the pixel opening area A2. This is beneficial to improving the uniformity of the display panel 100 and reducing the difference in reflectivity and hue between the photosensitive area A1 and the pixel opening area A2.

[0037] Please continue to refer to this. Figure 5This disclosure provides a display panel 100, wherein the light-transmitting hole K further includes a third light-transmitting hole K3, and the third light-transmitting hole K3 does not overlap with the second color resist 12 along a direction perpendicular to the light-emitting surface of the display panel 100.

[0038] In one optional embodiment provided in this disclosure, the light-transmitting hole K includes a first light-transmitting hole K1, with the second color resist 12 partially overlapping the first light-transmitting hole K1 along a direction perpendicular to the plane of the display panel 100; the light-transmitting hole K also includes a second light-transmitting hole K2, with the second color resist 12 covering the second light-transmitting hole K2 along a direction perpendicular to the plane of the display panel 100; the light-transmitting hole K further includes a third light-transmitting hole K3, which does not overlap with the second color resist 12 along a direction perpendicular to the plane of the display panel 100. Because the third light-transmitting hole K3 does not overlap with the second color resist 12, light entering the third light-transmitting hole K3 does not undergo any filtering processing, allowing the photosensitive device inside the display panel 100 to receive the most original and complete spectral information, which is beneficial for achieving lossless sensing of full-spectrum light. When the photosensitive device includes an under-display camera, the under-display camera can capture more realistic and richer color information from the third light-transmitting hole K3, reducing color cast. When the photosensitive device includes an ambient light sensor, the ambient light sensor can sense the intensity of ambient light through the third light-transmitting hole K3 and accurately sense the color temperature and spectral distribution of the ambient light, thereby achieving more intelligent and accurate screen brightness and color adjustment. By differentiating the overlapping areas of the first light-transmitting hole K1, the second light-transmitting hole K2, the third light-transmitting hole K3 and the second color resist 12 (partial overlap, complete coverage, no overlap), the accuracy and reliability of the entire photosensitive system inside the display panel 100 can be improved while satisfying the light transmittance of the photosensitive area A1, while also reducing the reflectivity of the photosensitive area A1 and the hue difference between the photosensitive area A1 and the pixel opening area A2.

[0039] In this way, by differentiating the overlapping areas of the first light-transmitting hole K1, the second light-transmitting hole K2, the third light-transmitting hole K3 and the second color resist 12, not only can high-fidelity light sensing of the photosensitive device be achieved, but the differences in reflectivity and hue between the pixel opening area A2 and the photosensitive area A1 can also be taken into account, which greatly enhances the reliability of the display panel 100.

[0040] Please refer to Figures 1 to 5 This disclosure provides a display panel 100, wherein the second color resist 12 is at least one of red, blue, and green color resists. That is, in this embodiment, the second color resist 12 has the same color type as the first color resist 11. Since the first color resist 11 of the display panel 100 includes red, green, and blue color resists, and the photosensitive area A1 uses the same color type of second color resist 12, it can be manufactured using the same process as the first color resist 11, without requiring additional steps, thus simplifying the manufacturing process.

[0041] Please refer to Figure 3 This disclosure provides a display panel 100 in which the thickness H of the second color resist 12 is greater than or equal to 1µm and less than or equal to 4µm.

[0042] Optionally, along the direction perpendicular to the plane of the display panel 100, the thickness H of the second color resist 12 can be greater than or equal to 1µm and less than or equal to 3µm; or, the thickness H of the second color resist 12 can be greater than or equal to 1µm and less than or equal to 2µm; or, the thickness H of the second color resist 12 can be greater than or equal to 2µm and less than or equal to 4µm; or, the thickness H of the second color resist 12 can be greater than or equal to 2µm and less than or equal to 3µm... and so on. They are not listed one by one here. It is sufficient that the thickness H of the second color resist 12 is greater than or equal to 1µm and less than or equal to 4µm. If the thickness H of the second color resist 12 is less than 1µm, the thickness H of the second color resist 12 is too thin and cannot effectively absorb external light, which is not conducive to reducing the reflectivity of the light-transmitting hole K, and thus not conducive to reducing the reflectivity of the photosensitive area A1; if the thickness H of the second color resist 12 is greater than 4µm, the thickness H of the second color resist 12 is too thick, which is not conducive to the thinning of the display panel 100, and can also easily lead to excessive attenuation of light incident from the light-transmitting hole K, which is not conducive to the accurate perception of light by the photosensitive device 01.

[0043] Thus, by setting the thickness H of the second color resist 12 within the range of greater than or equal to 1µm and less than or equal to 4µm, this thickness H range takes into account the manufacturing process and long-term reliability, which helps ensure that the second color resist 12 is not easily broken or detached during manufacturing and use, thereby improving the durability and reliability of the display panel 100. The thickness range of the second color resist 12 is highly compatible with the current manufacturing process of the display panel 100 and can be seamlessly integrated into existing production lines, reducing manufacturing costs and technical risks. The second color resist 12 within this thickness range can both ensure the normal light response of the photosensitive device and block the reflected light emitted from the light-transmitting hole K to a certain extent, reducing the reflectivity of the photosensitive area A1. The second color resist 12 with a certain thickness H is located on the side of the light-transmitting hole K facing the light-emitting surface of the display panel 100, which can change the hue of the light-transmitting hole K, making it closer to the hue of the sub-pixels in the display area, which helps improve the uniformity of the display panel 100.

[0044] Figure 6 As shown Figure 1 Please refer to another planar schematic diagram of the central photosensitive area. Figure 6This disclosure provides a display panel 100, wherein the photosensitive area A1 includes a plurality of light-transmitting holes K. Along a direction perpendicular to the light-emitting surface of the display panel 100, the overlapping area of ​​the light-transmitting hole K away from the center of the photosensitive area A1 and the second color resist 12 is larger than the overlapping area of ​​the light-transmitting hole K near the center of the photosensitive area A1 and the second color resist 12.

[0045] In one optional embodiment provided in this disclosure, the overlap area between the light-transmitting aperture K, which is far from the center of the photosensitive area A1, and the second color resist 12 is set to be larger than the overlap area between the light-transmitting aperture K, which is close to the center of the photosensitive area A1 and the second color resist 12. That is, the overlap area between the light-transmitting aperture K, which is close to the center of the photosensitive area A1, and the second color resist 12 is set to be smaller, so that more of the light-transmitting aperture K, which is close to the center of the photosensitive area A1, is exposed outside the second color resist 12. This is beneficial for the light-transmitting aperture K, which is close to the center of the photosensitive area A1, to receive more external light and improve the light-gathering efficiency of the center of the photosensitive area A1. The overlap area between the light-transmitting aperture K, which is far from the center of the photosensitive area A1, and the second color resist 12 is set to be larger, so that more of the light-transmitting aperture K, which is far from the center of the photosensitive area A1, is blocked by the second color resist 12. This is beneficial for reducing the reflectivity of the light-transmitting aperture K, which is far from the center of the photosensitive area A1, and reducing the reflectivity difference between the photosensitive area A1 and the pixel opening area A2. In this embodiment, the light-transmitting hole K (with low light-gathering efficiency) far from the center of the photosensitive area A1 is overlapped by a larger area of ​​the second color resist 12, while the light-transmitting hole K (with high light-gathering efficiency) at the center of the photosensitive area A1 is overlapped by a smaller area of ​​the second color resist 12. This differentiated overlapping design of "large on the outside and small on the inside" can further reduce the reflectivity of the light-transmitting hole K far from the center of the photosensitive area A1 while ensuring the amount of light entering the center of the photosensitive area A1. This is beneficial for blurring the boundary between the pixel opening area A2 and the photosensitive area A1, so as to achieve the "hiding" effect of the photosensitive area A1.

[0046] In addition, the light-transmitting hole K in the center of the photosensitive area A1 is less affected by stray light from the light-emitting element D, while the light-transmitting hole K far from the center of the photosensitive area A1 is more affected by stray light from the light-emitting element D. By increasing the overlap area between the photosensitive area A1 far from the center of the photosensitive area A1 and the second color resist 12, stray light obliquely incident from the light-emitting element D can be filtered out more effectively, reducing light crosstalk.

[0047] Figure 7 As shown Figure 1 Another planar schematic diagram of the central photosensitive area. Figure 8 As shown Figure 1 Please refer to another planar schematic diagram of the central photosensitive area. Figure 7 and Figure 8 This disclosure provides a display panel 100 in which different light-transmitting holes K in the photosensitive area A1 overlap with the second color resist 12 in the same area.

[0048] In one optional embodiment provided in this disclosure, the photosensitive area A1 includes a plurality of light-transmitting holes K. Along the direction of the light-emitting surface of the display panel 100, at least one light-transmitting hole K at least partially overlaps with the second color resist 12, wherein the overlap area between different light-transmitting holes K and the second color resist 12 is the same. Optionally, the orthographic projection shapes of different second color resists 12 on the plane of the display panel 100 may be the same, thus ensuring that the overlap area between different light-transmitting holes K and the second color resist 12 is the same. Please refer to... Figure 7 The second color resist 12 overlaps with the first light-transmitting hole K1 to form a first area, and the second color resist 12 overlaps with the second light-transmitting hole K2 to form a second area. The second color resist 12 corresponding to the first light-transmitting hole K1 and the second color resist 12 corresponding to the second light-transmitting hole K2 have the same orthographic projection shape, and the first area and the second area have the same size.

[0049] Alternatively, the orthographic projection shapes of different second color resists 12 on the plane of the display panel 100 may differ, but the overlap area between different light-transmitting holes K and the second color resists 12 may be the same. Please refer to... Figure 8 The second color resist 12 overlaps with the first light-transmitting hole K1 to form a third area, and the second color resist 12 overlaps with the second light-transmitting hole K2 to form a fourth area. The orthographic projection shape of the second color resist 12 corresponding to the first light-transmitting hole K1 is annular, and the orthographic projection shape of the second color resist 12 corresponding to the second light-transmitting hole K2 is rectangular. That is, the orthographic projection shapes of the second color resist 12 corresponding to the first light-transmitting hole K1 and the second color resist 12 corresponding to the second light-transmitting hole K2 are different, but the third area and the fourth area are the same size.

[0050] It is also possible that the orthographic projection shapes of different second color resists 12 on the plane where the display panel 100 is located are different, and the overlapping shapes of different light-transmitting holes K and second color resists 12 are different, but the overlapping area is the same...etc. This disclosure does not limit this, as long as the overlapping area of ​​different light-transmitting holes K and second color resists 12 in the photosensitive area A1 is the same. Figure 7 The only difference is that the orthographic projection shapes of the different second color resists 12 are the same. Figure 8 The illustration is based on the example where the overlapping area of ​​different light-transmitting holes K and the second color resist 12 is the same.

[0051] The design of uniformly overlapping areas between different light-transmitting holes K and the second color resist 12 in the photosensitive area A1 ensures that the area blocked by the second color resist 12 is the same for each light-transmitting hole K. This results in the same amount of external light absorbed by different second color resists 12, and a similar reduction in the amount of reflected light from different light-transmitting holes K. Consequently, the degree of reflectivity reduction among different light-transmitting holes K is the same or similar, which helps to uniformly reduce the reflectivity of various areas in the photosensitive area A1, thereby improving the uniformity of the display panel 100. Thus, by setting the overlapping area of ​​different light-transmitting holes K and the second color resist 12 in the photosensitive area A1 to be the same, the reflectivity of various areas within the photosensitive area A1 can be uniformly reduced, which is beneficial to improving the uniformity of the display panel 100.

[0052] Figure 9 As shown Figure 1 Another planar schematic diagram of the central photosensitive area. Figure 10 As shown Figure 1 Please refer to another planar schematic diagram of the central photosensitive area. Figure 7 , Figures 9 to 10 This disclosure provides a display panel 100 in which the orthographic projection shapes of different second color resists 12 are the same in the overlapping areas formed by different light-transmitting holes K and second color resists 12.

[0053] In one optional embodiment provided in this disclosure, the photosensitive area A1 includes a plurality of light-transmitting holes K. Along the direction of the light-emitting surface of the display panel 100, at least one light-transmitting hole K at least partially overlaps with the second color resist 12, wherein the overlapping areas of different light-transmitting holes K and the second color resist 12 are the same, and the orthographic projection shapes of different second color resists 12 are the same. Optionally, please refer to... Figure 10 The orthographic projection shape of different second color resists 12 onto the plane of the display panel 100 is rectangular, and the overlapping area of ​​the rectangular second color resists 12 with different light-transmitting holes K is the same; or, please refer to Figure 9 The orthographic projection shape of different second color resists 12 onto the plane of the display panel 100 is a triangle, and the overlapping area of ​​the triangular second color resists 12 with different light-transmitting holes K is the same; or, please refer to Figure 7 The orthographic projection shape of different second color resists 12 onto the plane of the display panel 100 is annular, and the overlapping area of ​​the annular second color resists 12 with different light-transmitting holes K is the same...etc., this disclosure does not limit this. Figure 7 , Figure 9 , Figure 10 The second color resistor 12 is illustrated in the form of a ring, a triangle, and a rectangle, respectively.

[0054] As mentioned earlier, second color resists 12 of the same shape can be manufactured uniformly in the same process, which greatly simplifies the most critical photolithography manufacturing step, and helps to simplify the process and reduce costs. In this embodiment, by setting the shapes of different second color resists 12 to be the same, and using photomask patterns with consistent shapes, even if there are slight alignment errors during the manufacturing process, it will not have a significant impact on the consistency of the final overlapping area, which helps to improve the fault tolerance rate in the manufacturing process and reduce production costs and time.

[0055] Please refer to Figure 10 In one optional embodiment provided in this disclosure, the colors of the second color resists 12 overlapping with different light-transmitting holes K can be set to different colors. For example, the second color resist 12 overlapping with the first row of light-transmitting holes K can be set to red, the second color resist 12 overlapping with the second row of light-transmitting holes K can be set to blue, and so on. That is, the second color resists 12 located in different rows can be set to different colors, or the second color resists 12 located in different rows can be set to different colors in a regular alternation, or irregular alternation. Alternatively, the second color resists 12 located in different columns can be set to different colors, or the second color resists 12 located in different columns can be set to different colors in a regular alternation, or irregular alternation. Alternatively, the second color resists 12 overlapping with different light-transmitting holes K can be set to different colors irregularly, etc. This disclosure does not limit this. Figure 10 The example shown is to set the second color resistor 12 located in different rows to different colors.

[0056] Figure 11 As shown Figure 1 Please refer to another planar schematic diagram of the central photosensitive area. Figure 7 , Figures 9 to 11 This disclosure provides a display panel 100 in which different second color resists 12 and different light-transmitting holes K cover the same area.

[0057] In one optional embodiment provided in this disclosure, the photosensitive area A1 includes a plurality of light-transmitting holes K. Along the direction of the light-emitting surface of the display panel 100, at least one light-transmitting hole K at least partially overlaps with the second color resist 12, wherein the overlap area between different light-transmitting holes K and the second color resist 12 is the same, and the coverage area of ​​different second color resists 12 and different light-transmitting holes K is the same. Optionally, please refer to... Figure 9 and Figure 10 Different second color resists 12 may cover the left side of different light-transmitting holes K, or different second color resists 12 may cover the right side of different light-transmitting holes K, or different second color resists 12 may cover the upper side of different light-transmitting holes K, or different second color resists 12 may cover the lower side of different light-transmitting holes K, etc., and so on. They will not be listed one by one here. It is only necessary to satisfy that the coverage area of ​​different second color resists 12 and different light-transmitting holes K is the same. Figure 9 and Figure 10The illustration only takes the left side, where different second color resists 12 cover different light-transmitting holes K, as an example. Understandably, please refer to... Figure 11 Alternatively, different second color resists 12 can be configured to cover multiple of the left, right, upper, and lower sides of different light-transmitting holes K, as long as the coverage area of ​​different second color resists 12 and different light-transmitting holes K is the same.

[0058] In this embodiment, under the premise that the overlapping area of ​​different second color resists 12 and different light-transmitting holes K is set to be the same, the coverage area of ​​different second color resists 12 and different light-transmitting holes K is further set to be the same, so that the shape, size and position of different second color resists 12 are consistent, and the same photomask can be used to achieve repeatable and precise processing, which is beneficial to simplifying the manufacturing process. Different second color resists 12 cover the same area as different light-transmitting holes K, which can absorb light from the same position in different light-transmitting holes K. This helps to reduce the reflectivity of the same position in different light-transmitting holes K, and also helps to uniformly reduce the reflectivity of each light-transmitting hole K in the photosensitive area A1, reducing the reflectivity difference between the pixel opening area A2 and the photosensitive area A1. Different second color resists 12 cover the same area as different light-transmitting holes K, which allows the same position of different light-transmitting holes K to be covered by the second color resist 12. This makes the hue change position of the light-transmitting holes K the same, which helps to improve the hue uniformity of the light-transmitting holes K, thereby reducing the hue difference between the pixel opening area A2 and the photosensitive area A1, and improving the uniformity of the display panel 100. Thus, by setting the coverage areas of different second color resists 12 and different light-transmitting holes K to be the same, it is beneficial to uniformly reduce the reflectivity of each light-transmitting hole K in the photosensitive area A1, improve the hue uniformity of different light-transmitting holes K in the photosensitive area A1, and reduce the reflectivity and hue differences with the pixel opening area A2.

[0059] Please refer to Figures 1 to 11 This disclosure provides a display panel 100 in which the reflectance difference between the pixel aperture area A2 and the photosensitive area A1 is less than or equal to 0.1%.

[0060] Optionally, the reflectance difference between the pixel aperture area A2 and the photosensitive area A1 can be less than or equal to 0.09%, or the reflectance difference between the pixel aperture area A2 and the photosensitive area A1 can be less than or equal to 0.08%, or the reflectance difference between the pixel aperture area A2 and the photosensitive area A1 can be less than or equal to 0.07%, or the reflectance difference between the pixel aperture area A2 and the photosensitive area A1 can be less than or equal to 0.06%, or the reflectance difference between the pixel aperture area A2 and the photosensitive area A1 can be less than or equal to 0.05%, etc., and so on. They are not listed one by one here. It is sufficient to satisfy that the reflectance difference between the pixel aperture area A2 and the photosensitive area A1 is less than or equal to 0.1%. In the above embodiments and accompanying drawings, the percentage of the overlapping area between the second color resist 12 and the light-transmitting hole K is only for illustration. The specific percentage can be set according to actual customer needs. In order to reduce the difference in reflectivity between the pixel opening area A2 and the photosensitive area A1, while meeting the minimum requirements for the transmittance of various colors of light, the difference in reflectivity between the two needs to be controlled below 0.1%.

[0061] When the reflectivity difference between pixel aperture area A2 and photosensitive area A1 is less than or equal to 0.1%, this minute difference is beyond the range of human eye perception. This means that under any lighting conditions, users will hardly notice the presence of photosensitive area A1, thus minimizing the visual "hole" in the display panel 100 and achieving a display effect closer to a hole-free, complete screen. This provides users with a truly full-screen experience and has higher aesthetic value. When the reflectivity difference between pixel aperture area A2 and photosensitive area A1 is less than or equal to 0.1%, their light absorption and reflection characteristics are very similar. This reduces light scattering and reflection within the display panel 100, improves the quality of light received by the photosensitive device, and reduces stray light interference. Therefore, by controlling the reflectivity difference between pixel aperture area A2 and photosensitive area A1 to below 0.1%, a display effect close to a hole-free, complete screen can be achieved, providing users with a seamless and flawless new experience.

[0062] Figure 12 The figure shown is a plan view of a display device provided in an embodiment of this disclosure. Please refer to it. Figure 12 This disclosure provides a display device 200, including the display panel 100 as described above. The display device 200 provided in this disclosure can be any electronic device with display functionality, such as a touch screen, mobile phone, tablet computer, laptop computer, e-reader, or television. The display device 200 provided in this disclosure has the beneficial effects of the display panel 100 provided in this disclosure. For details, please refer to the specific descriptions of the display panel 100 in the above embodiments; these descriptions will not be repeated here.

[0063] Understandable Figure 12The shape of the display device 200 is illustrated using only a right-angled rectangle structure as an example. In some other embodiments of this disclosure, the display device 200 may also be circular, elliptical or any other feasible shape, and this disclosure does not specifically limit it in this regard.

[0064] In summary, the present disclosure provides a display panel and display device, comprising: a pixel aperture area and a photosensitive area, wherein a light-emitting element is disposed in the pixel aperture area and a light-transmitting hole is disposed in the photosensitive area; the display panel includes a filter layer located on one side of the light-emitting surface of the light-emitting element, the filter layer including a first color resist overlapping the light-emitting element; the filter layer including a second color resist at least partially overlapping at least one light-transmitting hole. By setting the second color resist to at least partially overlap with at least one light-transmitting hole, the transmittance of the light-transmitting hole can be relatively reduced, thereby reducing the difference in reflectance between the photosensitive area and the display area when the display panel is in the off state. In addition, the setting of the second color resist can also change the hue of the light-transmitting hole, improving display uniformity. By configuring the second color resist to create different overlap areas with the first and second light-transmitting holes, the amount of reflected light blocked by different overlap areas varies. This allows for differentiated reflectivity design of different light-transmitting holes within the photosensitive area while meeting light transmission requirements. It also reduces the reflectivity difference between the photosensitive area and the display area, improving the display uniformity of the panel when the screen is off. Furthermore, by configuring the first light-transmitting hole within the photosensitive area to partially overlap with the second color resist in the thickness direction of the display panel, and configuring the second light-transmitting hole to completely overlap with the second color resist in the thickness direction of the display panel, the reflectivity of the photosensitive area can be further reduced. This further reduces the reflectivity difference between the photosensitive area and the display area when the screen is off, contributing to improved display panel uniformity. By differentiating the overlapping areas of the second color resists corresponding to the first and second light-transmitting holes, and setting the colors of the second color resists corresponding to the first and second light-transmitting holes to be the same, the reflectivity of the photosensitive area can be reduced. Using the same color for the second color resists greatly simplifies the manufacturing process, reduces costs, and improves the feasibility of mass production. Furthermore, the colors of the second color resists corresponding to the first and second light-transmitting holes can also be set to be different, which helps to make the hue of the light-transmitting holes in the photosensitive area approximate that of the display area.

[0065] The above description is merely a specific embodiment of this disclosure, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this disclosure. Therefore, this disclosure is not to be limited to the embodiments described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
