[0002] The present invention relates to the field of display technology, and in particular to a display panel and a display device including the display panel. Background Art

[0003] With the continuous development of display technology, consumers' requirements for display panels are constantly increasing. Various types of display panels have emerged and have developed rapidly, such as liquid crystal display panels, organic light-emitting display panels, etc. On this basis, display technologies such as 3D display, touch display technology, curved display, ultra-high resolution display and anti-peep display are constantly emerging to meet consumer needs.

[0004] In addition, in recent years, more and more functions have been gradually integrated into display panels, such as fingerprint recognition, light-sensing touch, facial recognition, or iris recognition. However, functions such as fingerprint recognition and facial recognition require light to pass through the display panel and illuminate the sensing device installed on the backlight surface of the display panel, which requires the display panel to have a sufficiently high light transmittance. However, with the increasing resolution of current display panels, the sub-pixels are distributed more and more densely, and accordingly, the number of pixel circuits is also increasing. The transistors in the pixel circuits are all formed by metal layers, which make it difficult for light to pass through the display panel, reducing the transmittance of the display panel. Therefore, how to further improve the light transmittance of the display panel while ensuring that the display panel has a higher resolution, so as to achieve accurate fingerprint recognition and facial recognition functions, is a technical problem that needs to be solved in this field.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] It should be noted that the following description sets forth specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in a variety of other ways than those described herein, and those skilled in the art may make similar generalizations without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] refer to Figure 1 , Figure 1 It is a structural schematic diagram of a display panel provided by an embodiment of the present invention, wherein the display panel 10 includes a sub-pixel array, the sub-pixel array includes a plurality of sub-pixels 101 arranged in an array, a first display area 110 and a second display area 120, and the light transmittance of the non-luminous area of ​​the second display area 120 is greater than the light transmittance of the non-luminous area in the first display area 110; wherein the distribution density of the sub-pixels 101 in the second display area 120 is less than the distribution density of the sub-pixels 101 in the first display area 110, and the luminous area of ​​the sub-pixels in the second display area 120 is greater than the luminous area of ​​the sub-pixels 101 presenting the same luminous color in the first display area 110.

[0024] It should be noted that the display panel 10 provided in this embodiment may be an organic light-emitting display panel, wherein the organic light-emitting display panel includes an anode and a cathode, and an organic light-emitting layer located between the anode and the cathode. A voltage applied between the anode and the cathode excites carrier migration, which acts on the organic light-emitting layer, thereby emitting light. In other implementations of this embodiment, the display panel 10 may also be other display panels, such as a quantum dot light-emitting display panel, a nanochip light-emitting display panel, etc., which will not be further described in this embodiment.

[0025] In addition, it should be noted that if Figure 1 As shown, since the distribution density of sub-pixels in the second display area 120 is relatively small, the center distance between the sub-pixels is relatively large. Therefore, the area between the sub-pixels is the high-transmittance area 102. Generally, the face recognition device or fingerprint recognition device can be set in the area corresponding to the high-transmittance area 102, so that the face recognition device or fingerprint recognition device can fully receive the light signal, thereby realizing an accurate unlocking function.

[0026] As can be seen from the above description, the display panel and display device provided in this embodiment include a first display area 110 and a second display area 120, wherein the display panel 10 includes a first display area 110 and a second display area 120, wherein the light transmittance of the second display area 120 is greater than that of the first display area 110, the distribution density of sub-pixels in the second display area 120 is less than that of the first display area 110, and the light-emitting area of ​​the sub-pixels in the second display area 120 is greater than the light-emitting area of ​​sub-pixels of the same light-emitting color in the first display area 110. This design, on the one hand, improves the light transmittance in the second display area 120 by reducing the distribution density of sub-pixels in the second display area 120. However, reducing the sub-pixel density results in a decrease in the aperture ratio of the sub-pixels in the second display area 120. Therefore, by increasing the light-emitting area of ​​the sub-pixels in the second display area 120, the aperture ratios of the first display area 110 and the second display area 120 are made consistent, thereby ensuring uniform brightness of the display panel.

[0027] In this embodiment, optionally, the light transmittance T1 of the non-luminous area in the first display area 110 and the light transmittance T2 of the non-luminous area in the second display area 120 satisfy the following relationship: 3≤T2 / T1≤50. Since the area generally used for setting up devices such as fingerprint recognition or facial recognition is only a portion of the display panel, to ensure normal display of the display panel, only a portion of the display panel (the second display area 102) is set as a high-transmittance area, while the other areas can remain normal display areas. When the transmittance of the high-transmittance area satisfies the above ratio, light can be fully transmitted, thereby ensuring that the display panel can achieve accurate fingerprint recognition or facial recognition functions.

[0028] like Figure 1 As shown, in this embodiment, the display panel 10 includes a gate signal line 111 extending along a first direction X and a data line 112 extending along a second direction Y. The first direction X intersects with the second direction Y. The gate signal line 111 is connected to a gate driving circuit to provide a gate driving signal to the sub-pixel 101. The data line 112 is connected to a driving chip to provide a data signal to the sub-pixel 101. In particular, in this embodiment, the first direction X intersects with the second direction Y.

[0029] Furthermore, in this embodiment, the sub-pixels in the second display area 120 are R1 times the width of the sub-pixels in the first display area 110 that emit the same luminous color in the first direction X, and the sub-pixels in the second display area 120 are R2 times the width of the sub-pixels in the first display area 110 that emit the same luminous color in the second direction Y; the ratio of the center distance between adjacent sub-pixels in the second display area 120 in the first direction X to the center distance between adjacent sub-pixels in the first display area 110 in the first direction X is R3, and the ratio of the center distance between adjacent sub-pixels in the second display area 120 in the second direction Y to the center distance between adjacent sub-pixels in the first display area 110 in the second direction Y is R4, wherein 0.8≤(R1×R2) / (R3×R4)≤1.2. Figure 2 , Figure 2 : is a schematic diagram of a sub-pixel aperture ratio provided by an embodiment of the present invention, wherein the center spacing between adjacent sub-pixels in the first direction X is P1, and the center spacing between adjacent sub-pixels in the second direction is P2, then the area S of the dotted area in the figure is P1×P2, and the sub-pixel aperture ratio is the ratio of the sub-pixel area in the dotted area to the area of ​​the dotted area. As described above, if the sub-pixel in the second display area 120 is R1 times the width of the sub-pixel in the first display area 110 along the first direction and R2 times the width along the second direction, then the area of ​​the sub-pixel in the dotted area in the second display area 120 is (R1×R2) times the area of ​​the sub-pixel in the dotted area in the first display area 110. Since P1 in the second display area 120 is R3 times the P1 in the first display area 110, the area of ​​the sub-pixel in the dotted area in the second display area 120 is (R1×R2) times the area of ​​the sub-pixel in the dotted area in the first display area 110. 0 is R4 times the P2 in the first display area 110. Therefore, the area of ​​the dotted area in the second display area 120 is (R3×R4) times the area of ​​the dotted area in the first display area 110. Therefore, the aperture ratio of the second display area 120 is [(R1×R2) / (R3×R4)] times the aperture ratio of the first display area 110. Therefore, if the aperture ratios of the first display area 110 and the second display area 120 are to be consistent, it is necessary to make [(R1×R2) / (R3×R4)] approach to 1 or equal to 1. In this embodiment, 0.8≤(R1×R2) / (R3×R4)≤1.2 is defined. Within this range, the aperture ratios of the first display area 110 and the second display area 120 can be made uniform, thereby making the overall brightness of the display panel uniform.

[0030] The above situation is a case where the area magnification of the sub-pixels of various colors between the second display area 120 and the first display area 110 is the same. In other embodiments, the magnification of the sub-pixels varies depending on the color.

[0031] Optionally, in this embodiment, the display panel 10 includes at least red sub-pixels, green sub-pixels and blue sub-pixels, wherein, in the ratio of the luminous areas of the sub-pixels 101 in the second display area 120 and the sub-pixels 101 presenting the same luminous color in the first display area 110, the ratio of the luminous areas of the green sub-pixels is smaller than the ratio of the luminous areas of the red sub-pixels and / or the ratio of the luminous areas of the blue sub-pixels, because among various colors, the green sub-pixels have the highest visual sensitivity in the human eye. Therefore, the light loss caused by the appropriate reduction of the luminous area of ​​the green sub-pixels is smaller than that of the red and blue lights. Generally, in the display panel, the green sub-pixels require a smaller luminous area to meet the display requirements. Therefore, in this embodiment, in order to further increase the light transmittance of the second display area 120, the luminous area of ​​the green sub-pixels in the second display area 120 can be designed to be smaller, and the brightness of the second display area 120 can also be ensured.

[0032] In this embodiment, reference Figure 3 , Figure 3 1 is a schematic diagram of the structure of a sub-pixel provided by an embodiment of the present invention, wherein the sub-pixel 101 includes an anode 130 and a pixel circuit 131. In the second display area 120, the anode 130 and the pixel circuit 131 extend in the same direction, and in the direction perpendicular to the surface of the display panel 10, the anode 130 and the pixel circuit 131 overlap with each other. With such a design, on the one hand, when the anode 130 and the pixel circuit 131 extend in the same direction and overlap with each other, the overlap between the anode 130 and the pixel circuit 131 can be made as high as possible. Because the pixel circuit is the main structure that affects the transmittance of the non-luminous area, when the pixel circuit 131 is located as much as possible below the area covered by the anode 130, the area of ​​the pixel circuit 131 extending into the non-luminous area can be reduced, thereby improving the light transmittance of the non-luminous area. It should also be noted that the light-emitting area of ​​the aforementioned sub-pixel 101 is close to or even equal to the area of ​​the anode 130. This is because in an organic light-emitting element, the light emitted by the light-emitting layer is reflected by the anode 130 and emitted from the light-emitting side. Therefore, the light-emitting area of ​​the sub-pixel corresponds to the anode. In addition, it should be noted that the figure is only a schematic diagram of the pixel circuit 131. Generally, the pixel circuit 131 includes several transistors and capacitors. For example, a 6T1C pixel circuit includes 6 transistors and 1 capacitor. The specific structure of the pixel circuit is not described in detail in this embodiment.

[0033] Furthermore, in this embodiment, in the second display area 120, the anode 130 completely covers the pixel circuit 131 in at least one of the first direction X or the second direction Y. For example, if the anode 130 completely covers the pixel circuit 131 in the first direction X, no metal film layer of the pixel circuit is present between two adjacent sub-pixels in the first direction X, thereby achieving a high light transmittance in the region between the adjacent sub-pixels. In particular, the anode 130 can completely cover the pixel circuit 131 in both the first direction X and the second direction Y, thereby achieving a high light transmittance in both the region between adjacent sub-pixels in the first direction X and the region between adjacent sub-pixels in the second direction Y.

[0034] In addition, in this embodiment, optionally, the aspect ratio of the driving transistor in the pixel circuit of the sub-pixel in the second display area 120 is greater than the aspect ratio of the driving transistor in the pixel circuit of the sub-pixel exhibiting the same luminous color in the first display area 110. This is because the sub-pixels in the second display area 120 have a larger area than the sub-pixels exhibiting the same luminous color in the first display area 110, and the distribution density of the sub-pixels in the second display area 120 is less than the distribution density of the sub-pixels in the first display area 110. Therefore, the sub-pixels in the second display area 120 need to achieve the same brightness as the sub-pixels in the first display area 110. Since the driving capability of the pixel circuit is related to the aspect ratio of the driving transistor therein, the driving transistor in the pixel circuit corresponding to the sub-pixel in the second display area 120 has a larger aspect ratio, thereby ensuring uniform brightness of the sub-pixels in the two display areas.

[0035] Optionally, in this embodiment, refer to Figure 4 , Figure 4 This is a partial schematic diagram of a second display area provided by an embodiment of the present invention, wherein in the second display area 120, at least two adjacent sub-pixels 101 share the same pixel circuit. Such a design can further reduce the area of ​​the pixel circuit and further improve the light transmittance of the non-luminous area.

[0036] As previously mentioned, the light-emitting area of ​​the sub-pixel 101 in the second display area 120 is greater than the light-emitting area of ​​the sub-pixel 101 in the first display area 110. Under this premise, the specific difference between the light-emitting areas of the two can take many forms, which are described in detail in the following embodiments:

[0037] In this embodiment, reference Figure 5-Figure 7 , wherein, along the first direction X, the center distance between adjacent sub-pixels in the first display area 110 and the second display area 120 satisfies: P12=R3×P11, R3≥1;

[0038] Along the second direction Y, the center distances between adjacent sub-pixels in the first display area 110 and the second display area 120 satisfy: P22=R4×P21, R4≥1.

[0039] In one embodiment, reference Figure 5 , Figure 5 This is a partial schematic diagram of a display panel provided by an embodiment of the present invention. Along a first direction X, the widths of sub-pixels emitting the same luminous color in the first and second display areas 110, 120 satisfy the following: W11 = W12. Along a second direction Y, the widths of sub-pixels emitting the same luminous color in the first and second display areas 110, 120 satisfy the following: W22 = M1 × W21, where M1 > 1. This means that the sub-pixels in the second display area 120 are larger than the sub-pixels emitting the same luminous color in the first display area 110 only in the second direction. This design eliminates the need for winding or folding lines when extending the data lines 112 in the second direction Y from the first display area 110 to the second display area 120, simplifying the manufacturing process.

[0040] Further optionally, in this embodiment, M1=4, R3×R4=4.

[0041] According to the aforementioned calculation method for the aperture ratio, when M1=4 and R3×R4=4, the aperture ratios of the first display area 110 and the second display area 120 can be made consistent, thereby ensuring the brightness uniformity of the display panel. It should be noted that in other optional embodiments, M1 and (R3×R4) can also take other values. It is only necessary to make M1=(R3×R4) to make the aperture ratios of the first display area 110 and the second display area 120 consistent, thereby ensuring the brightness uniformity of the display panel. In addition, in this embodiment, the center distance between two adjacent sub-pixels along the first direction X in the second display area 120 can be set to be larger. Therefore, the fingerprint recognition or face recognition detection device can be installed between two adjacent sub-pixels along the first direction X in the second display area 120.

[0042] In another embodiment, reference Figure 6 , Figure 6 This is a partial schematic diagram of another display panel provided by an embodiment of the present invention. Along a first direction X, the widths of sub-pixels emitting the same color in the first display area 110 and the second display area 120 satisfy the following: W12 = N1 × W11, where N1 > 1. Along a second direction Y, the widths of sub-pixels emitting the same color in the first display area 110 and the second display area 120 satisfy the following: W21 = W22. In this case, the arrangement of the fingerprint recognition or facial recognition detection device can be specifically matched and can be selected as needed.

[0043] Further optionally, in this embodiment, N1=4, R3×R4=4.

[0044] According to the aforementioned calculation method for the aperture ratio, when N1=4 and R3×R4=4, the aperture ratios of the first display area 110 and the second display area 120 can be made consistent, thereby ensuring the brightness uniformity of the display panel. It should be noted that in other optional embodiments, N1 and (R3×R4) can also take other values. It is only necessary to make N1=(R3×R4) to make the aperture ratios of the first display area 110 and the second display area 120 consistent, thereby ensuring the brightness uniformity of the display panel. In addition, in this embodiment, the center distance between two adjacent sub-pixels along the second direction Y in the second display area 120 can be set to be larger. Therefore, the fingerprint recognition or face recognition detection device can be installed between two adjacent sub-pixels along the second direction Y in the second display area 120.

[0045] In yet another embodiment, reference Figure 7 , Figure 7 This is a partial schematic diagram of another display panel provided by an embodiment of the present invention. Along a first direction X, the widths of sub-pixels emitting the same color in the first and second display areas 110, 120 satisfy the following equation: W12 = M2 × W11, where M2 > 1. Along a second direction Y, the widths of sub-pixels emitting the same color in the first and second display areas 110, 120 satisfy the following equation: W21 = N2 × W22, where N2 > 1. This design allows for flexible configuration of the sub-pixel size in the second display area 120. In actual use, this type of display panel can be selected based on the structure of fingerprint or facial recognition devices.

[0046] Further optionally, in this embodiment, M2=2, N2=2, R3×R4=4.

[0047] According to the aforementioned calculation method of the aperture ratio, when M2=2, N2=2, and R3×R4=4, the aperture ratios of the first display area 110 and the second display area 120 can be made consistent, thereby ensuring the brightness uniformity of the display panel.

[0048] In addition, it should be noted that in the above embodiments, the display panel 10 is described as including red sub-pixels (R), green sub-pixels (G), and blue sub-pixels (B). In other optional embodiments, the display panel 10 can also include four sub-pixels or more seed pixels, and this embodiment does not make any special limitations on this.

[0049] In addition, it should be noted that in the above embodiment, the data line 112 extends from the first display area 110 to the second display area 120. Since the number of sub-pixels in the second display area 120 is less than that in the first display area 110, only part of the data line extends from the first display area 110 to the second display area 120. This will cause different loads on different data lines in the display panel. In order to balance the load, in this embodiment, a compensation element can be connected to the data line that does not extend to the second display area 120. The compensation element can specifically be a compensation capacitor or a compensation resistor. By providing the compensation element, the load on the data line with a small number of connected sub-pixels can be increased, thereby balancing the load on each data line, so that the brightness of each area of ​​the display panel is uniform.

[0050] Optional, reference Figure 8 , Figure 8 is a schematic diagram of a display panel provided by an embodiment of the present invention, wherein the display panel 10 includes a non-display area 130 embedded in the second display area 120, and the non-display area 130 is a groove or hole structure. Since full-screen is currently the mainstream development trend in the display industry, and the biggest challenge currently faced by full-screen is the placement of the front camera, a groove or hole structure is generally provided on one side of the full-screen for accommodating the front camera. In this application, the non-display area 130 is embedded in the second display area 120, so that the front camera and facial recognition device can be placed in one part of the display screen, while the rest of the display provides normal display, which can be more conducive to improving the display effect and user experience.

[0051] Another aspect of the embodiments of the present invention provides a display device, comprising the display panel in any one of the above embodiments.

[0052] refer to Figure 9 , Figure 9 FIG2 is a schematic diagram of a display device provided in an embodiment of the present invention, wherein display device 20 includes a display panel 10. Display panel 10 is a display panel in any of the aforementioned embodiments. Display device 20 may be a mobile phone, a laptop computer, a television, a watch, a smart wearable display device, or the like, and this embodiment does not specifically limit this. In this embodiment, a facial recognition device is provided in the area corresponding to second display area 120 of display device 20. The facial recognition device receives infrared light through the light-transmitting area of ​​the second display area to recognize a human face, thereby implementing the corresponding unlocking function.

[0053] As can be seen from the above description, the display panel and display device provided by the embodiments of the present invention include a first display area 110 and a second display area 120, wherein the display panel 10 includes a first display area 110 and a second display area 120, wherein the light transmittance of the second display area 120 is greater than the light transmittance of the first display area 110, the distribution density of sub-pixels in the second display area 120 is less than the distribution density of sub-pixels in the first display area 110, and the light-emitting area of ​​the sub-pixels in the second display area 120 is greater than the light-emitting area of ​​sub-pixels of the same light-emitting color in the first display area 110. This design, on the one hand, improves the light transmittance in the second display area 120 by reducing the distribution density of sub-pixels in the second display area 120, but reducing the sub-pixel density results in a decrease in the aperture ratio of the sub-pixels in the second display area 120. Therefore, by increasing the light-emitting area of ​​the sub-pixels in the second display area 120, the aperture ratios of the first display area 110 and the second display area 120 are made consistent, thereby ensuring uniform brightness of the display panel. The light transmittance of the second display area 120 is increased, and a face recognition device can be set in the area corresponding to the position with greater transmittance, so that the face recognition device can fully receive the light signal to achieve an accurate unlocking function.

[0054] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
