At present, the intelligent adjustment of display screens is mainly achieved by detecting ambient light through ambient light sensors in the display screen, including ambient light sensors using multiple detection schemes such as visible light and infrared light, and the display screen adjusts various display parameters according to the detection results.

[0003] The COE technology that currently replaces the polarizer of the display screen reduces the module thickness of the screen, which is beneficial to the bending performance of the folding screen. However, the current polarizer-free structure uses a nearly opaque shading design, which reduces the transmittance of the non-pixel area. In order to realize the function of the ambient light sensor to sense ambient light, a light-transmitting hole is formed by digging out part of the shading material in the non-pixel area. However, the light-transmitting hole set in this way has the problem of a small field of view (FOV). Summary of the invention

[0030] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0031] In a display panel using COE technology, a light shielding portion is provided in the filter layer for shielding light, and the pixel definition portion in the light-emitting layer is also mostly formed of a light shielding material. Therefore, it is necessary to open a through hole in the light shielding portion and the pixel definition portion to meet the transmittance requirement of the ambient light sensor to the display panel, so that light of sufficient intensity can reach the ambient light sensor.

[0032] When the light source illuminates the screen, the size of the through hole set in the shading part is the same as the size of the through hole set in the pixel definition part. It should be noted that the same here does not require that the size of the through hole set in the shading part is exactly the same as the size of the through hole set in the pixel definition part, as long as the sizes of the two are basically the same. And because the two are in different film layer structures of the display panel. Therefore, there is a spacing between the two due to the height difference of the film layer structure. The two through holes of the same size and the distance between them will cause the through hole set in the shading part and the through hole set in the pixel definition part to form an aperture. The formed aperture will intercept large-angle light, resulting in a reduction in the field of view (FOV) angle.

[0033] Among them, the field of view angle range of the ambient light sensor is the angle range when the transmittance of light incident to the ambient light sensor drops to half of the transmittance of light incident vertically to the ambient light sensor, that is, the transmittance of light incident to the ambient light sensor at the edge of the field of view angle of the ambient light sensor is half of the transmittance of light incident vertically to the ambient light sensor.

[0034] As for the ambient light sensor, its field of view will affect its ability to sense light. Therefore, the field of view of the ambient light sensor is one of the core indicators of its ability. Generally, the half-angle of the field of view of a display panel with a polarizer but no shading structure is 55 degrees. The half-angle of the field of view of a display panel with a shading structure and corresponding openings instead of a polarizer is generally 25 to 30 degrees, which is smaller than the field of view of a display panel with a polarizer but no shading structure.

[0035] If the field of view of the ambient light sensor is too small, the range of light that can be sensed by the ambient light will be smaller. Since the light emitted by the screen and the ambient light are constantly changing, there will be large parameter differences between the light emitted by the screen and the ambient light in different ranges. The smaller field of view of the ambient light sensor means that the range of the light emitted by the screen and the ambient light sensed by it is reduced. Among them, especially for the light emitted by the screen, the ambient light sensor cannot detect the light in various ranges emitted by the screen well at a smaller field of view, especially for the parameters of the screen light sensitivity and the screen color temperature, the reported values ​​are low. The ambient light sensor reports low values ​​for the parameters of the screen light sensitivity and the screen color temperature, which brings about practical problems such as dim screen brightness and inaccurate color temperature when the display panel is in use, which seriously affects the user experience.

[0036] In order to solve the aforementioned problem, an embodiment of the present application provides a display panel 10 . Figure 1 FIG. 1 shows a top view of the display panel 10. Figure 1As shown, the display panel 10 includes an adjacent display area 101 and a sensing area 102. The portion of the display panel 10 located in the display area 101 is used to display images. The portion of the display panel 10 located in the sensing area 102 is at least used to enable the sensor to sense corresponding parameters through the portion of the display panel 10 located in the sensing area 102. That is, in addition to the aforementioned functions, the portion of the display panel 10 located in the sensing area 102 may also have other functions, such as being used to display images.

[0037] It should be noted that Figure 1 The arrangement of the display area 101 and the sensing area 102 shown is only a feasible embodiment, but is not limited thereto in other embodiments.

[0038] Figure 2 FIG. 1 is a schematic diagram showing the structure of a display panel 10. Figure 2 As shown, the display panel 10 further includes: a substrate 11 , a light emitting layer 12 and a filter layer 13 .

[0039] The light emitting layer 12 is located between the substrate 11 and the filter layer 13 , and the filter layer 13 is located on the side of the light emitting layer 12 facing away from the substrate 11 .

[0040] The filter layer 13 includes a light shielding portion 131 and a light filtering portion 132. The light shielding portion 131 is adjacent to the light filtering portion 132 and surrounds the light filtering portion 132. Figure 3 The top view starting from the filter layer 13 is shown. Figure 3 The first direction X and the second direction Y are shown. The light shielding portion 131 is adjacent to the filter portion 132 and surrounds the filter portion 132 , that is, the light shielding portion 131 is adjacent to the filter portion 132 on the plane formed by the first direction X and the second direction Y, and the light shielding portion 131 surrounds the filter portion 132 on the plane formed by the first direction X and the second direction Y.

[0041] The light-emitting layer 12 includes a pixel definition portion 121 and a light-emitting portion 122. The pixel definition portion 121 is adjacent to the light-emitting portion 122 and surrounds the light-filtering portion 132. The light-emitting portion 122 and the light-filtering portion 132 are disposed correspondingly. Figure 3 In the top view of the filter layer 13 shown, the pixel definition portion 121 is adjacent to the light emitting portion 122 and surrounds the filter portion 132, that is, the pixel definition portion 121 is adjacent to the light emitting portion 122 on the plane formed by the first direction X and the second direction Y, and the pixel definition portion 121 surrounds the filter portion 132 on the plane formed by the first direction X and the second direction Y.

[0042] The filter layer 13 further includes a first through hole 133 penetrating the light shielding portion 131 along the thickness direction of the display panel 10. The light emitting layer 12 further includes a second through hole 123 penetrating the pixel defining portion 121 along the thickness direction of the display panel 10. In the sensing area 102, the orthographic projection of the first through hole 133 on the light emitting layer 12 is located in the second through hole 123.

[0043] The thickness direction of the display panel 10 is Figure 2 The third direction Z is shown. The first through hole 133 penetrates the light shielding portion 131 in the third direction Z, and the second through hole 123 penetrates the pixel defining portion 121 in the third direction Z.

[0044] By providing the first through hole 133 in the filter layer 13 and the second through hole 123 in the light emitting layer 12, and making the orthographic projection of the first through hole 133 in the light emitting layer 12 located in the second through hole 123, the light path between the first through hole 133 and the second through hole 123 can form a light cone with a triangular cross section. Specifically, the light cone with a triangular cross section formed by the light path between the first through hole 133 and the second through hole 123 can refer to Figure 2 The optical path G1 shown in FIG. By making the optical path between the first through hole 133 and the second through hole 123 form a light cone with a triangular cross section, a light path G2 corresponding to the light path G1 can be formed on the side of the first through hole 133 facing away from the second through hole 123, and the light path G2 is symmetrical with the light path G1 along the first direction X. Therefore, the optical path G2 can also form a light cone with a triangular cross section, and the vertex angle G3 of the cross section of the light cone formed by the optical path G2 is the same as the vertex angle of the cross section of the light cone formed by the optical path G1. The vertex angle G3 formed by the optical path G2 is the field of view angle of the ambient light sensor, and the range of the light cone formed by the optical path G2 is the sensing range of the ambient light sensor.

[0045] It should be noted that since the first through hole 133 and the second through hole 123 include various shapes, that is, the first through hole 133 and the second through hole 123 include various shapes on the plane formed by the first direction X and the second direction Y, the light cone mentioned above is not limited to be a positive cone.

[0046] Therefore, by setting a first through hole 133 in the filter layer 13 and a second through hole 123 in the light-emitting layer 12, and making the orthographic projection of the first through hole 133 in the light-emitting layer 12 located within the second through hole 123, a larger light cone range of the incident light can be formed through the first through hole 133 and the second through hole 123, and the formation of an aperture can be avoided. Therefore, while ensuring the transmittance of the display panel 10, the field of view angle of the ambient light sensor can be improved, and the sensing range of the ambient light sensor can be effectively improved. Furthermore, problems such as dim brightness of the display panel and inaccurate color temperature can be avoided, thereby effectively improving the user experience of the display panel 10.

[0047] In some embodiments, Figure 2 and Figure 3 As shown, the first through hole 133 has the same shape as the second through hole 123. The first through hole 133 has the same shape as the second through hole 123, that is, the shape of the first through hole 133 on the plane formed by the first direction X and the second direction Y is the same as the shape of the second through hole 123 on the plane formed by the first direction X and the second direction Y.

[0048] Furthermore, it should be noted that the first through hole 133 and the second through hole 123 having the same shape does not require that the first through hole 133 and the second through hole 123 have completely the same shape, but only requires that the first through hole 133 and the second through hole 123 have substantially the same shape. For example, the first through hole 133 and the second through hole 123 may be circular and elliptical, respectively, or the first through hole 133 and the second through hole 123 may be elliptical with different curvatures of corresponding sides, or the first through hole 133 and the second through hole 123 may be rectangular and square, respectively, but are not limited thereto.

[0049] The side length of the second through hole 123 is greater than or equal to 1.1 times the corresponding side length of the first through hole 133 , and less than or equal to 2 times the corresponding side length of the first through hole 133 .

[0050] For example, refer to Figure 3 The first side L1 of the first through hole 133 and the second side L2 of the second through hole 123 are shown. When the side length of the second through hole 123 is 1.1 times the corresponding side length of the first through hole 133, the length of the second side L2 is 1.1 times the first side L1. When the side length of the second through hole 123 is 2 times the corresponding side length of the first through hole 133, the length of the second side L2 is 2 times the first side L1.

[0051] Specifically, the field of view angle 1 is the half-angle of the vertex angle G3 formed by the first through hole 133 and the second through hole 123 in the second direction Y, that is, the angle of half the vertex angle of the triangle of the cross section of the light cone formed by the optical path G2 in the second direction Y. The field of view angle 2 is the half-angle of the vertex angle G3 formed by the first through hole 133 and the second through hole 123 in the first direction X, that is, the angle of half the vertex angle of the triangle of the cross section of the light cone formed by the optical path G2 in the first direction X. The line graph of the relationship between the field of view angle 1 and the size multiple of the second through hole 123 can be referred to Figure 4 As shown, Figure 4 The vertical axis is the angle of the field of view 1, in degrees (°). Figure 4 The horizontal axis is the multiple of the size of the second through hole 123. The line graph of the relationship between the field of view angle 2 and the multiple of the size of the second through hole 123 can be referred to Figure 5 As shown. Among them, Figure 5The vertical axis is the angle of the field of view 2, in degrees (°). Figure 5 The horizontal axis shown is a multiple of the size of the second through hole 123 .

[0052] pass Figure 4 and Figure 5 The line graph clearly shows that the angles of the viewing angle 1 and the viewing angle 2 gradually increase with the increase of the size multiple of the second through hole 123. Figure 5 It can be seen that the field of view angle 2 increases slowly before the size multiple of the second through hole 123 is greater than or equal to 1.1, and at this time, the size difference between the first through hole 133 and the second through hole 123 is small, and the size of the vertex angle G3 cannot be effectively increased. Therefore, when the side length of the second through hole 123 needs to be greater than or equal to 1.1 times the corresponding side length of the first through hole 133. When the size multiple of the second through hole 123 is greater than 2, the size of the second through hole 123 is larger, and its opening range is easy to cover the wiring in the display panel 10. Since the wiring is generally made of metal, if more wiring appears within the range of the second through hole 123, it will affect the optical path G1 between the first through hole 133 and the second through hole 123, and further affect the optical path G2.

[0053] By making the side length of the second through hole 123 greater than or equal to 1.1 times the corresponding side length of the first through hole 133 and less than or equal to 2 times the corresponding side length of the first through hole 133, the vertex angle G3 formed by the first through hole 133 and the second through hole 123 can be expanded while effectively avoiding the formation of an aperture. Therefore, the field of view of the ambient light sensor can be further improved while ensuring the transmittance of the display panel 10, and the sensing range of the ambient light sensor can be further improved. Furthermore, the problems of dim brightness of the display panel and inaccurate color temperature can be avoided, thereby effectively improving the user experience of the display panel 10.

[0054] In some embodiments, the side length of the second through hole 123 includes 1.5 times the corresponding side length of the first through hole 133. Figure 4 and Figure 5 As shown in the figure, when the side length of the second through hole 123 is 1.5 times the corresponding side length of the first through hole 133, the half-angles of the field of view angle 1 and the field of view angle 2 can ensure the sensing range of the ambient light sensor while avoiding the second through hole 123 being too large to affect the wiring design in the display panel 10.

[0055] Furthermore, when the side length of the second through hole 123 is 1.5 times the corresponding side length of the first through hole 133, the size of the second through hole 123 is not much larger than the size of the first through hole 133. Therefore, the side length of the second through hole 123 is 1.5 times the corresponding side length of the first through hole 133, which can effectively prevent the size of the second through hole 123 from being too large and causing too much impact on the wiring layout in the display panel 10, that is, it can prevent the wiring in the display panel 10 from being too large due to the size of the second through hole 123 being too large, and requiring too much design adjustment to avoid the second through hole 123.

[0056] Therefore, by making the side length of the second through hole 123 include 1.5 times the corresponding side length of the first through hole 133, it is possible to effectively ensure the sensing range of the ambient light sensor while avoiding the excessive impact of the second through hole 123 that is too large on the wiring layout within the display panel 10. Therefore, it is possible to avoid problems such as dim brightness of the display panel and inaccurate color temperature, effectively improve the user experience of the display panel 10, and avoid the excessive impact of the second through hole 123 that is too large on the wiring layout within the display panel 10.

[0057] In some embodiments, Figure 2 and Figure 3 As shown, the shapes of the first through hole 133 and the second through hole 123 include rectangles. Specifically, the shapes of the first through hole 133 and the second through hole 123 on the plane formed by the first direction X and the second direction Y may include a variety of shapes, for example, the shapes of the first through hole 133 and the second through hole 123 may be circular, or the shapes of the first through hole 133 and the second through hole 123 may be triangular, or the shapes of the first through hole 133 and the second through hole 123 may be rectangular, but are not limited thereto.

[0058] Preferably, the first through hole 133 and the second through hole 123 are rectangular in shape. Since the wiring in the display panel 10 is mostly arranged in sequence in directions perpendicular to each other, for example, the wiring in the display panel 10 can be arranged in sequence along the first direction X and the second direction Y. At this time, by making the first through hole 133 and the second through hole 123 rectangular in shape, the appearance of the first through hole 133 and the second through hole 123 can correspond to the wiring arrangement mode in the display panel 10, so that it is convenient to avoid the wiring in the display panel 10 to avoid the coverage range of the first through hole 133 and the second through hole 123.

[0059] Moreover, due to the influence of the exposure process precision, although the first through hole 133 and the second through hole 123 are designed to be rectangular, they will actually form rounded rectangles. With the improvement of the exposure process, the shapes of the first through hole 133 and the second through hole 123 formed eventually will be closer to rectangles.

[0060] Since the wiring in the display panel 10 can be arranged in sequence along the first direction X and the second direction Y, the wiring in the display panel 10 will form a rectangular non-wiring portion. By making the shapes of the first through hole 133 and the second through hole 123 rectangular, the shapes of the first through hole 133 and the second through hole 123 can be better matched with the non-wiring portion. Therefore, the first through hole 133 and the second through hole 123 with a rectangular shape can obtain the largest light-transmitting area, thereby effectively improving the light transmittance of the display panel 10.

[0061] In some embodiments, the distance between the first through hole 133 and the second through hole 123 in the thickness direction of the display panel 10 is less than 13.8 micrometers. Specifically, the distance between the first through hole 133 and the second through hole 123 may be 12.3 micrometers, or the distance between the first through hole 133 and the second through hole 123 may be 10.3 micrometers, but is not limited thereto, and the distance between the first through hole 133 and the second through hole 123 may also be other values ​​within the range of less than 13.8 micrometers.

[0062] 13.8 microns is the currently common minimum spacing between the light emitting layer 12 and the filter layer 13. By making the distance between the first through hole 133 and the second through hole 123 in the thickness direction of the display panel 10 less than 13.8 microns, that is, the distance in the third direction Z is less than 13.8 microns, the spacing between the first through hole 133 and the second through hole 123 can be reduced, that is, Figure 2 The height of the cross-sectional triangle of the light cone formed by reducing the optical path G1 can be enlarged by reducing the height of the triangle while keeping the base of the triangle unchanged, thereby correspondingly enlarging the vertex angle G3. By enlarging the vertex angle G3, the field of view of the ambient light sensor can be correspondingly enlarged, thereby increasing the sensing range of the ambient light sensor.

[0063] Therefore, by increasing the spacing between the first through hole 133 and the second through hole 123, the light cone range of the incident light formed by the first through hole 133 and the second through hole 123 can be expanded, and the formation of an aperture can be avoided. Thus, while ensuring the transmittance of the display panel 10, the field of view angle of the ambient light sensor can be further improved, and the sensing range of the ambient light sensor can be further improved. Furthermore, problems such as dim brightness of the display panel and inaccurate color temperature can be further avoided, thereby effectively improving the user experience of the display panel 10.

[0064] In some embodiments, Figure 2 As shown, the display panel 10 further includes a drive array layer 14. The drive array layer 14 is located between the substrate 11 and the light emitting layer 12, and the drive array layer 14 is used to drive the light emitting layer 12 to perform a light emitting function.

[0065] refer to Figure 6The driving array layer 14 shown is a schematic diagram of the structure corresponding to the light emitting layer 12 and the filter layer 13. The driving array layer 14 includes a plurality of driving traces 141. The orthographic projections of the first through hole 133 and the second through hole 123 in the driving array layer 14 are both located outside the driving traces 141.

[0066] It should be noted that the orthographic projections of the first through hole 133 and the second through hole 123 on the driving array layer 14 are located outside the driving wiring 141, and it is not required that the orthographic projections of the second through hole 123 on the driving array layer 14 do not completely overlap with the driving wiring 141. Figure 6 As shown, the second through hole 123 and the driving trace 141 may have a small overlapped portion, but the small overlapped portion will not have a significant impact on the optical path G1 formed by the first through hole 133 and the second through hole 123 .

[0067] With such a configuration, the driving line 141 can be designed to be avoided so that there is no driving line 141 in the range covered by the first through hole 133 and the second through hole 123, or only a small part of the driving line 141 exists. Therefore, it can be avoided that the driving line 141 has a significant impact on the optical path G1 formed by the first through hole 133 and the second through hole 123, and further, it can be avoided that the display panel brightness is dim and the color temperature is inaccurate, and the user experience of the display panel 10 is effectively improved.

[0068] In some embodiments, Figure 2 As shown, the display panel 10 further includes a touch layer 15. The touch layer 15 is located between the filter layer 13 and the light emitting layer 12. Figure 7 The touch layer 15 shown corresponds to the structural schematic diagram of the light emitting layer 12 and the filter layer 13, and the touch layer 15 includes a plurality of touch lines 151 for receiving touch instructions. Specifically, the touch lines 151 can receive touch instructions by forming a capacitor with a touch indicator (e.g., a finger and a stylus, etc.).

[0069] The orthographic projections of the first through holes 133 on the touch layer 15 are all located outside the touch traces 151 .

[0070] Since the distance between the touch wiring 151 and the filter layer 13 in the third direction Z is relatively small, it is only necessary to ensure that the orthographic projection of the first through hole 133 in the touch layer 15 is located outside the touch wiring 151 to ensure that the setting of the touch wiring 151 will not affect the optical path G1 formed by the first through hole 133 and the second through hole 123.

[0071] With such a configuration, the touch line 151 can be designed to be avoided so that the touch line 151 does not exist in the range covered by the first through hole 133 and the second through hole 123. Therefore, the touch line 151 can be prevented from having a significant impact on the optical path G1 formed by the first through hole 133 and the second through hole 123. Furthermore, problems such as dim brightness of the display panel and inaccurate color temperature can be further avoided, thereby effectively improving the user experience of the display panel 10.

[0072] In some embodiments, the materials of the light shielding portion 131 and the pixel defining portion 121 both include black light shielding material.

[0073] In this way, the light shielding portion 131 and the pixel defining portion 121 can better prevent the lights emitted by adjacent sub-pixels in the light emitting layer 12 from crosstalking with each other.

[0074] In some embodiments, Figure 2 As shown, the light emitting portion 122 includes at least three sub-pixels 1221 arranged in an array, and the filter portion 132 correspondingly includes at least three filters 1321 arranged in an array. Specifically, the light emitting portion 122 may include a red sub-pixel 1221R, a green sub-pixel 1221G, and a blue sub-pixel 1221B, and the filter portion 132 may be provided with a red filter 1321R, a green filter 1321G, and a blue filter 1321B, but is not limited thereto.

[0075] The orthographic projection of the sub-pixel 1221 on the filter layer 13 is located inside the filter 1321 .

[0076] With such a configuration, the light emitted by the corresponding sub-pixel 1221 can be filtered by the filter 1321, thereby further avoiding crosstalk between the lights emitted by adjacent sub-pixels 1221, and the ambient light incident on the part of the sub-pixel 1221 corresponding to the display panel 10 can be filtered by the filter 1321, thereby reducing the influence of the ambient light on the display effect of the display panel 10. For example, the influence of the ambient light on the display contrast of the display panel 10 can be avoided.

[0077] In some embodiments, Figure 2 As shown, the light emitting layer 12 of the display panel 10 further includes a cathode 125 and a plurality of anodes 124. The cathode 125 may be a surface electrode, or may be a surface electrode using a patterning process. The plurality of anodes 124 are arranged corresponding to the sub-pixels 1221 arranged in an array.

[0078] In some embodiments, Figure 2 As shown, the filter layer 13 further includes a flat layer 134. The flat layer 134 is used to fill the uneven portion caused by other structures of the filter layer 13, so that the side of the filter layer 13 facing away from the substrate 11 remains flat.

[0079] In some embodiments, Figure 2 As shown, a packaging layer 16 is provided between the touch layer 15 and the light emitting layer 12. The packaging layer 16 is used to package and protect the light emitting layer 12 and the drive array layer 14 to prevent water vapor and oxygen from invading the light emitting layer 12 and the drive array layer 14.

[0080] In addition, a bonding layer 17 and a glass cover plate 18 are provided on the side of the filter layer 13 facing away from the substrate 11. The bonding layer 17 is used to bond the glass cover plate 18 to the filter layer 13. The glass cover plate 18 is used to protect the remaining film structures in the display panel 10.

[0081] The present application also provides a display device, including any one of the above display panels 10. The display device also includes a sensor. The sensor is located in the sensing area 102. The sensor is located on the side of the substrate 11 facing away from the light-emitting layer 12, and is arranged corresponding to the second through hole 123.

[0082] The sensor may include a variety of sensors that need to receive external light, such as an ambient light sensor and an imaging sensor, etc. In this embodiment, the sensor may be an ambient light sensor.

[0083] By configuring in this way, the size of the extended vertex angle G3 of the first through hole 133 and the second through hole 123 can be specifically realized, and the field of view of the ambient light sensor can be correspondingly enlarged.

[0084] The above embodiments of the present application may complement each other if no conflict occurs.

[0085] It should be noted that in the accompanying drawings, the sizes of layers and regions may be exaggerated for clarity of illustration. It is also understood that when an element or layer is referred to as being "on" another element or layer, it may be directly on the other element, or there may be an intermediate layer. In addition, it is understood that when an element or layer is referred to as being "under" another element or layer, it may be directly under the other element, or there may be more than one intermediate layer or element. In addition, it is also understood that when a layer or element is referred to as being "between" two layers or two elements, it may be the only layer between the two layers or two elements, or there may also be more than one intermediate layer or element. Similar reference numerals throughout the text indicate similar elements.

[0086] The term "plurality" means two or more than two, unless expressly limited otherwise.
