Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] The Pol-Less (PLP) technology can significantly improve the light output efficiency of the display panel by removing the polarizer on the light output side of the display panel, thereby increasing the display brightness and reducing the panel power consumption. However, after the polarizer is removed, the reflectivity on the light output side of the display panel is too high, which seriously affects the display effect. In order to reduce the reflectivity, the polarizer-free display panel uses a full black pixel definition layer with a black matrix to block the metal pattern and cathode, and only sets openings in the luminous pixel area for light output. This design results in almost zero light transmittance. Without special design, the light sensor cannot work properly.

[0003] In order to improve the light transmittance of the photosensitive area corresponding to the light sensor in the non-polarizer type display panel so that the light sensor can work normally on the display panel, the relevant technology forms a light-transmitting area in the photosensitive area through a winding design, and opens holes in the black pixel definition layer and the black matrix to improve the light transmittance of the photosensitive area; however, due to the design difference between the photosensitive area and the normal display area, the brightness difference between the two is large when working, and different gamma calibration compensation is required for the photosensitive area and the normal display area. As the number of light sensors increases, multiple gamma curves need to be designed for individual calibration, which prolongs the debugging time and reduces the production efficiency of the display panel.

[0069] At the same time, by reducing the number of pixel circuits 1120 in the second display area 200, thereby reducing the density of pixel circuits 1120 in the second display area 200, more space can be provided for the overall layout of the display panel 1, facilitating more sophisticated pixel arrangement and optical design, and reducing production costs and shortening manufacturing cycles.

[0070] Furthermore, the pixel definition layer 12 is also provided with a plurality of light-transmitting openings 122 located in the second display area 200, and the light-transmitting openings 122 are arranged in alignment with the light-transmitting area 201. The light-shielding layer 162 is also provided with a plurality of second openings 1622 located in the second display area 200, and the first openings 1621 are arranged corresponding to the first type of sub-pixels 181 and the second type of sub-pixels 182, thereby ensuring that functions of different sub-pixels of the display panel 1 are not affected, and the second openings 1622 are arranged in alignment with the light-transmitting openings 122, thereby ensuring that the optical element has sufficient light transmittance in the light-transmitting area 201 in the second display area 200, thereby ensuring that the optical element can work normally and accurately collect ambient light information, thereby improving the performance and response speed of the display panel 1.

[0071] Among them, by controlling the diameter of the circumscribed circle of the second opening 1622, the luminous flux of the light-transmitting area 201 can be controlled, thereby effectively adjusting the light intensity required by the optical element, and avoiding the accuracy of the optical element being affected by excessive light exposure; specifically, by adjusting the opening size, the transmittance of the light-transmitting area 201 can be flexibly adjusted under different production requirements, so that the display panel 1 can ensure good display brightness and optical element performance in different usage scenarios; and, by controlling the diameter of the circumscribed circle of the second opening 1622, it can be ensured that the light passing through the light-transmitting area 201 is limited to the area required by the optical element, so that the light-transmitting area 201 is only displayed at a specific position of the display panel 1 (such as the edge or non-core display area), which can reduce the impact of the light-transmitting area 201 on the visual effect and avoid the excessively large second opening 1622 causing the light-transmitting area 201 to be exposed or interfere with the beauty of the display area.

[0072] Please combine Figure 1 , Figure 2 , Figure 3 and Figure 4 ;in, Figure 4 This is a schematic diagram of the first gamma curve and the second gamma curve provided in an embodiment of the present application.

[0073] In one embodiment, the multiple first-category sub-pixels 181 are all configured as a first gamma curve, and the second-category sub-pixels 182 in the multiple first pixel portions 1911 are all configured as a second gamma curve, and the voltages corresponding to the same gray scale in the first gamma curve and the second gamma curve are respectively a first voltage and a second voltage, and the first voltage is greater than the second voltage, so that the display brightness of the first display area 100 and the second display area 200 are kept consistent, thereby improving the overall display effect of the display panel 1; and, by configuring at least part of the second pixel circuits 11202 in the entire second display area 200 to use the same set of gamma curves, a unified debugging and calibration standard can be adopted for at least part of the second pixel circuits 11202 in the second display area 200, without the need to individually adjust different gamma curves for each second pixel circuit 11202, thereby reducing the workload of manual calibration, shortening the debugging time, and improving the production efficiency of the display panel 1.

[0074] Specifically, the first driving transistor 11211A and the second driving transistor 11211B are both P-type thin film transistors. It can be understood that in a P-type thin film transistor, when the voltage (or gate voltage) increases, the gate generates a stronger reverse electric field on the hole channel between the source and the drain, resulting in a decrease in the hole concentration in the channel, thereby reducing the current passing through the channel; therefore, by adjusting the voltage, precise control of the current can be achieved, so that the display panel can achieve the expected brightness and color performance.

[0075] It is understandable that the "one-drive-many" design may cause the corresponding sub-pixels to fail to reach high brightness, that is, when a single pixel circuit drives multiple sub-pixels of the same color at the same time, its current output capacity is limited, resulting in the multiple sub-pixels connected to it being unable to reach the preset high brightness value, thereby causing the display brightness of this area to be inconsistent with the display brightness of other normally driven display areas (such as the "one-drive-one" design), thereby affecting the overall display effect; in the embodiment of the present application, the first driving transistor 11211A and the second driving transistor 11211B are both P-type thin film transistors, and the first voltage is greater than the second voltage, The amount of current flowing through the first driving transistor 11211A of the first pixel circuit 11201 and the second driving transistor 11211B of the second pixel circuit 11202 per unit time are differentiated by design, so that the amount of current flowing through the second driving transistor 11211B per unit time is larger, thereby improving the current output capacity of the second pixel circuit 11202, which is beneficial to improving the display brightness of the second type of sub-pixel 182 electrically connected to the second pixel circuit 11202 in the second display area 200, so that the display brightness of the first display area 100 and the second display area 200 remain consistent, thereby improving the overall display effect of the display panel 1.

[0076] Please combine Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Figures 7a to 7d ;in, Figure 5 The embodiments of the present application provide Figure 1 Schematic diagram of the local cross section corresponding to O-Oˋ; Figure 6 A schematic diagram of the arrangement of sub-pixels in the first display area and the second display area provided in an embodiment of the present application; Figure 7a The embodiments of the present application provide Figure 6 The enlarged schematic diagram of point A in the middle; Figure 7b The embodiments of the present application provide Figure 6 The enlarged schematic diagram of point B in the middle; Figure 7c The embodiments of the present application provide Figure 6 The enlarged schematic diagram of the center C; Figure 7d The embodiments of the present application provide Figure 6 Enlarged schematic diagram of point D in the middle.

[0077] In one embodiment, the multiple first display sub-areas 210 include a first sub-area 211 and a second sub-area 212, and the first sub-area 211 and the second sub-area 212 are each provided with a plurality of first repeating units 191, and the first repeating unit 191 includes the first pixel portion 1911 and the light-transmitting portion 1912; wherein the number of the first repeating units 191 per unit area in the first sub-area 211 is greater than the number of the first repeating units 191 per unit area in the second sub-area 212, so that a unified debugging and calibration standard can be adopted for the first sub-areas 211 and the second sub-areas 212 of different sizes, thereby reducing the workload of manual calibration, shortening the debugging time, and improving the production efficiency of the display panel 1.

[0078] Both the first sub-area 211 and the second sub-area 212 can be optical element areas, and the optical element areas are used to set optical elements to provide necessary optical functions; specifically, a plurality of the first pixel parts 1911 and a plurality of the light-transmitting parts 1912 are provided in the optical element area, and one first pixel part 1911 and one light-transmitting part 1912 constitute the first repeating unit 191; wherein, the light-transmitting part 1912 is located in the light-transmitting area 201, and the light-transmitting part 1912 is set corresponding to the optical element, which can provide sufficient light for the optical element, thereby helping to improve the sensitivity of the optical element.

[0079] It can be understood that by setting the number of the first repeating units 191 per unit area in the first sub-area 211 to be greater than the number of the first repeating units 191 per unit area in the second sub-area 212, the first sub-area 211 and the second sub-area 212 can respectively correspond to different optical elements, that is, according to the number of the first repeating units 191, the transmittance of different areas is adjusted to adapt to different optical elements, and the size of the light-transmitting area 201 domain can be flexibly optimized according to the optical element's demand for light; for example, the optical element in the first sub-area 211 may require a higher light transmittance to ensure that it can fully receive and process external light signals when working. Therefore, by increasing the number of the first repeating units 191 in the first sub-area 211, the number of light-transmitting parts 1912 in this area is larger, thereby providing a larger luminous flux to meet the needs of high-sensitivity optical elements.

[0080] At the same time, compared with the prior art, as the number of optical elements increases, it is necessary to design a gamma curve for each optical element separately and perform individual calibration, which greatly prolongs the debugging time, increases the workload of manual calibration during the production process, and reduces the production efficiency of the display panel 1. In this embodiment, a plurality of first pixel portions 1911 are set in both the first sub-area 211 and the second sub-area 212, and in each of the first pixel portions 1911, a plurality of second light-emitting devices 13202 and a second pixel circuit 11202 are connected, thereby achieving a unified voltage drive of the plurality of second-type sub-pixels 182 in the first sub-area 211 and the second sub-area 212; specifically, the second-type sub-pixels 182 in the plurality of first pixel portions 1911 are all configured as the second gamma curve, thereby avoiding setting a different gamma curve for each optical element separately, reducing the manual adjustment work during the calibration process, and thereby improving the production efficiency of the display panel 1.

[0081] Moreover, the configuration of a unified gamma curve also helps to optimize the display effect of the display panel 1; it is understandable that since the sub-pixels in different areas use the same voltage and calibration standard, the brightness and color consistency of each part of the display panel 1 is ensured, avoiding the color difference problem caused by different gamma curves.

[0082] It should be noted that, in this embodiment, only the second display area 200 including the first sub-area 211 and the second sub-area 212 is used as an example for illustration. In another embodiment, the second display area may include the first sub-area, the second sub-area and the third sub-area, and the first sub-area, the second sub-area and the third sub-area are each provided with a plurality of first repeating units, and the first repeating unit includes the first pixel portion and the light-transmitting portion, and the transmittance of the first sub-area, the transmittance of the second sub-area and the transmittance of the third sub-area can be flexibly adjusted according to actual needs; wherein, the first sub-area, the second sub-area and the third sub-area can all be optical element areas, and the optical element area is used to set optical elements to provide necessary optical functions; the setting of multiple sub-areas enables the display panel to flexibly adjust the transmittance and pixel layout according to the needs of different optical elements.

[0083] Please continue to combine Figure 1 to Figure 7d In one embodiment, a plurality of first pixel rows 1901 and a plurality of light-transmitting rows 1902 are provided in each of the first sub-area 211 and the second sub-area 212. The plurality of first pixel rows 1901 and the plurality of light-transmitting rows 1902 are alternately arranged in sequence along the first direction Y. Each of the first pixel rows 1901 includes a plurality of first pixel portions 1911 arranged at intervals along the second direction X. Each of the light-transmitting rows 1902 includes a plurality of light-transmitting portions 1912 arranged at intervals along the second direction X. Thus, while ensuring the display effect of the first sub-area 211 and the second sub-area 212, the first sub-area 211 and the second sub-area 212 have sufficient light-transmitting areas to meet the light transmittance requirements of the optical element.

[0084] Among them, one of the light-transmitting portions 1912 is arranged between two adjacent first pixel portions 1911, so that the light-transmitting portion 1912 is evenly distributed and will not interfere with the pixel layout of the display area. In the display panel 1 that cooperates with the optical element, the "blind area" of the optical element area can be effectively reduced and its sensitivity can be improved; it should be noted that the "blind area" refers to the area within the optical element area, due to insufficient or blocked light-transmitting area 201, the optical element cannot receive enough light, thereby causing the area to be unable to effectively perceive or respond to external light signals.

[0085] It should be noted that, in this embodiment, the first direction is Figure 7a The Y direction in the second direction is Figure 7a The X direction in FIG. 1 is taken as an example to illustrate; specifically, in Figure 7a In the figure, the Y direction represents the longitudinal direction of the display panel 1, the X direction represents the horizontal direction of the display panel 1, and the first direction Y is perpendicular to the second direction X. Through the definitions in the above directions, the arrangement of sub-pixels in different display areas and their distribution in the display panel 1 can be clearly described.

[0086] Furthermore, since the light-transmitting portion 1912 is disposed adjacent to the first pixel portion 1911 , the light utilization efficiency of the optical element can be improved by controlling the shape and size of the light-transmitting portion 1912 , which helps to improve the overall performance of the display panel 1 .

[0087] Please continue to combine Figure 1 to Figure 7d In one embodiment, the second display area 200 further includes a plurality of second repeating units 192, and the plurality of second repeating units 192 are arranged around at least a portion of the plurality of first repeating units 191, and the second repeating unit 192 includes a second pixel portion 1921; wherein, the structure of the second pixel portion 1921 is the same as the structure of the first pixel portion 1911, and the second-type sub-pixels 182 in the plurality of second pixel portions 1921 are all configured as a second gamma curve, thereby configuring at least a portion of the second pixel circuits 11202 in the entire second display area 200 to use the same set of gamma curves, and a unified debugging and calibration standard can be adopted for at least a portion of the second pixel circuits 11202 in the second display area 200.

[0088] Specifically, the second repeating unit 192 includes a second pixel portion 1921, and the structure of the second pixel portion 1921 is the same as that of the first pixel portion 1911, so that the pixel layout of the second repeating unit 192 is consistent or similar to the pixel layout of the first repeating unit 191, ensuring the continuity and consistency of the display effect in the second display area 200, and achieving that the second type of sub-pixels 182 in the multiple second pixel portions 1921 and the second type of sub-pixels 182 in the multiple first pixel portions 1911 can adopt a unified debugging and calibration standard.

[0089] Furthermore, a plurality of second pixel rows 1903 are provided in the second display area 200, and the plurality of second pixel rows 1903 are arranged at intervals along the first direction Y, and each second pixel row 1903 includes a plurality of second repeating units 192 arranged at intervals along the second direction X; wherein the number of the second repeating units 192 in adjacent second pixel rows 1903 is the same or different, thereby providing flexibility and adjustability for the pixel layout of the second display area 200.

[0090] In the second display area 200, by controlling the number of the second repeating units 192 between the first sub-area 211 and the boundary of the second display area 200, the number of the second repeating units 192 between the second sub-area 212 and the boundary of the second display area 200, and the number of the second repeating units 192 between the first sub-area 211 and the second sub-area 212, it is possible to ensure that similar display effects are achieved in different areas of the second display area 200, thereby avoiding the problem of inconsistent local display effects.

[0091] At the same time, by adjusting the number of the second repeating units 192, the area of ​​the second display area 200 can be controlled; for example, by increasing or decreasing the number of the second repeating units 192, the second display area 200 can be expanded or reduced horizontally or vertically to meet different display needs; specifically, for display devices with different numbers of light-emitting elements, the size of the second display area 200 can be flexibly adjusted to meet the needs of different application scenarios.

[0092] It should be noted that, in a display panel equipped with multiple optical elements, the display panel usually needs to be set with multiple optical element areas, and one optical element area corresponds to one optical element setting; since the functional requirements, shapes, sizes, etc. between the multiple optical elements may be different, the shapes, sizes, transmittance and other parameters of the multiple optical element areas will also be different; for example, the display panel includes multiple optical element areas with irregular shapes, for these optical element areas, it is necessary to design multiple gamma curves for individual calibration, which prolongs the debugging time and reduces the production efficiency of the display panel.

[0093] It can be understood that, in this embodiment, by controlling the number of the second repeating units 192, a plurality of optical element areas with complex geometric shapes can be integrated into a second display area 200 with a regular shape, wherein the structure of the second pixel portion 1921 is the same as the structure of the first pixel portion 1911, and the second-type sub-pixels 182 in the plurality of second pixel portions 1921 and the second-type sub-pixels 182 in the plurality of first pixel portions 1911 are both configured with a second gamma curve, thereby configuring at least part of the second pixel circuits 11202 in the entire second display area 200 to use the same set of gamma curves, and a unified debugging and calibration standard can be adopted for at least part of the second pixel circuits 11202 in the second display area 200, without the need to individually adjust different gamma curves for each second pixel circuit 11202, thereby reducing the workload of manual calibration, shortening the debugging time, and improving the production efficiency of the display panel 1.

[0094] Please continue to combine Figure 1 to Figure 7dIn one embodiment, a plurality of third-category sub-pixels 183 are provided in the second display area 200, and the third-category sub-pixels 183 include the first pixel circuit 11201 and a third light-emitting device (not shown in the figure), and the third light-emitting device is connected to the first pixel circuit 11201; wherein the plurality of third-category sub-pixels 183 are all configured with a first gamma curve, thereby effectively shortening the individual adjustment time for each of the third-category sub-pixels 183 during the production process and improving production efficiency.

[0095] Specifically, in the first display area 100, a first light-emitting device 13201 is connected to a first pixel circuit 11201, and in the second display area 200, a third light-emitting device is connected to a first pixel circuit 11201, and the plurality of first-category sub-pixels 181 and the plurality of third-category sub-pixels 183 are all configured with a first gamma curve; in the second display area 200, in the first pixel portion 1911, a plurality of second light-emitting devices 13202 and a second pixel circuit 11202 are connected, and the plurality of second-category sub-pixels 182 in the first pixel portion 1911 are all configured with a second gamma curve.

[0096] Among them, the first type of sub-pixels 181, the second type of sub-pixels 182 and the third type of sub-pixels 183 all include but are not limited to one or more of red sub-pixels 1801, green sub-pixels 1802 and blue sub-pixels 1803, that is, red sub-pixels 1801, green sub-pixels 1802 and blue sub-pixels 1803 are provided in the first display area 100 and the second display area 200.

[0097] Specifically, the first type of sub-pixel 181 includes a red sub-pixel 1801, a green sub-pixel 1802 and a blue sub-pixel 1803 located in the first display area 100, the second type of sub-pixel 182 includes any one of the red sub-pixel 1801, the green sub-pixel 1802 and the blue sub-pixel 1803 located in the second display area 200, and the third type of sub-pixel 183 includes any two of the red sub-pixel 1801, the green sub-pixel 1802 and the blue sub-pixel 1803 located in the second display area 200 that are different from the second type of sub-pixel 182; wherein, this embodiment is illustrated by taking the example that the second type of sub-pixel 182 includes the blue sub-pixel 1803 located in the second display area 200, and the third type of sub-pixel 183 includes the red sub-pixel 1801 and the green sub-pixel 1802 located in the second display area 200.

[0098] It can be understood that the red sub-pixel 1801, the green sub-pixel 1802 and the blue sub-pixel 1803 in the first display area 100 all adopt a "one-drive-one" design, and the red sub-pixel 1801 and the green sub-pixel 1802 in the second display area 200 all adopt a "one-drive-one" design; multiple second light-emitting devices 13202 are connected to one second pixel circuit 11202, and the blue sub-pixels 1803 in the second display area 200 all adopt a "one-drive-many" design, so that the brightness of the entire display panel 1 can be adjusted through two sets of gamma curves without adjusting the gamma curve for each sub-pixel separately, thereby reducing the workload of manual calibration and making the manufacturing process of the display panel 1 simpler and more efficient.

[0099] Please continue to combine Figure 1 to Figure 7d In one embodiment, in the first display area 100 and the second display area 200, the plurality of red sub-pixels 1801 are arranged in multiple rows and columns in the first direction Y and the second direction X, the plurality of blue sub-pixels 1803 are arranged in multiple rows and columns in the first direction Y and the second direction X, and the plurality of green sub-pixels 1802 are arranged in multiple rows and columns in the first direction Y and the second direction X; wherein, a row of red sub-pixels 1801 and a row of green sub-pixels 1802 are provided between any two adjacent rows of the blue sub-pixels 1803; any row of the blue sub-pixels 1803 and an adjacent row of the red sub-pixels 1801 are alternately arranged, and any row of the red sub-pixels 1801 and an adjacent row of the green sub-pixels 1802 are provided in a one-to-one correspondence.

[0100] Specifically, in the first sub-area 211 and the second sub-area 212, along the first direction Y, the first pixel portion 1911 includes two adjacent blue sub-pixels 1803, and the two adjacent blue sub-pixels 1803 are electrically connected to the same second pixel circuit 11202, and along the first direction Y, a light-transmitting portion 1912 is arranged between the two adjacent first pixel portions 1911, so that in the first sub-area 211 and the second sub-area 212, the blue sub-pixel 1803 adopts a "one-drive-many" design, so that the number of pixel circuits 1120 in the second display area 200 is reduced, thereby reducing the coverage area of ​​the driving circuit, so that the pixel circuits 1120 in the first sub-area 211 and the second sub-area 212 can be easily set away from the light-transmitting area 201, so that the light-transmitting portion 1912 can be arranged between the two adjacent first pixel portions 1911, and there is enough space to arrange the pixel circuit 1120 while achieving local high transmittance.

[0101] Furthermore, in the second display area 200, along the first direction Y, the second pixel portion 1921 includes two adjacent blue sub-pixels 1803, and the two adjacent blue sub-pixels 1803 are electrically connected to the same second pixel circuit 11202, so that in the second display area 200, the blue sub-pixel 1803 adopts a "one-drive-many" design. It can be understood that since the structure of the second pixel portion 1921 is the same as that of the first pixel portion 1911, the blue sub-pixels 1803 in the multiple second pixel portions 1921 and the blue sub-pixels in the multiple first pixel portions 1911 can be configured with a second gamma curve, so that at least part of the second pixel circuits 11202 in the entire second display area 200 are configured to use the same set of gamma curves, and a unified debugging and calibration standard can be adopted for at least part of the second pixel circuits 11202 in the second display area 200, without the need to individually adjust different gamma curves for each second pixel circuit 11202, thereby reducing the workload of manual calibration, shortening the debugging time, and improving the production efficiency of the display panel 1.

[0102] It should be noted that any sub-pixel of any color located in the second display area 200 can adopt the "one-drive-many" design. Of course, only sub-pixels of some colors can adopt the "one-drive-many" design. This embodiment only takes the blue sub-pixel 1803 adopting the "one-drive-many" design as an example for illustration.

[0106] The display device 2 further includes a housing 21 , which is integrated with the display panel 1 to provide support, fixation and protection for the display panel 1 .

[0108] Furthermore, the display device 2 also includes at least two optical elements 22, one of the optical elements 22 is arranged corresponding to the first sub-area 211, and the other optical element 22 is arranged corresponding to the second sub-area 212; in some embodiments, the optical element 22 includes but is not limited to one of a camera, an infrared sensor, an ambient light sensor or a fingerprint reader.

[0109] In the embodiment of the present application, since the light transmittance of the second display area 200 of the display panel 1 is improved, the sensitivity of the optical element 22 is improved, and at the same time, the display effects of different areas of the display device 2 are kept consistent.
