Description

Technical Field

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

[0002] With the continuous development of display technology, organic light-emitting diodes (OLEDs) have been hailed as the "dream display" due to their advantages such as self-illumination, high efficiency, vibrant colors, thinness, energy saving, flexibility, and wide operating temperature range. In recent years, OLEDs have been widely used in consumer electronics, such as mobile phones and wearable devices, and their application in medium-sized laptops, tablets, and large-screen TVs is also increasing, gradually entering fields such as automotive displays and lighting.

[0003] The application of display panels in the automotive field needs to overcome the challenges posed by in-vehicle displays, especially instrument panels and central control screens, when projecting patterns onto the windshield at night or in low-light conditions. Because the windshield has a certain reflectivity, the light projected onto it will form an image on it and enter the eyes, interfering with the driver's vision and thus affecting driving safety.

DETAILED DESCRIPTION

[0065] Example implementations will now be described more fully with reference to the accompanying drawings. Example implementations may, however, be implemented in many different forms and should not be construed as limited to the implementations set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example implementations to those skilled in the art. Like reference numerals refer to like elements throughout the description and drawings. Additionally, the drawings are merely schematic and are not drawn to scale.

[0066] Although relative terms such as "upper," "lower," are used herein to describe one component's relationship to another component of the icon, these terms are used herein solely for convenience in describing the example as shown in the figures. It is to be understood that if the device of the icon is turned over so that what is described as the "upper" component becomes the "lower" component, then the described "upper" component becomes the "lower" component. When a structure is "on" another structure, it can mean that the structure is formed integrally with the other structure, or that the structure is "directly" on the other structure, or that the structure is "indirectly" on the other structure via another structure.

[0067] The terms "a," "an," "the," and "at least one" are used to mean one or more elements / components / features; the terms "comprises," "comprising," "includes," "including," and the like can mean the inclusion of an element or component or a group of elements or components having arbitrary values without limitation; and the terms "first," "second," and "third," and the like, merely mean different categories and do not indicate a limitation on the number of elements or components.

[0068] The display panel provided by the embodiments of the present disclosure can be applied in the field of vehicles to form a liquid crystal display for automotive (LCD). Notably, the display panel provided by the embodiments of the present disclosure can overcome the problem of the projection of a display screen, especially a center control screen, onto a front windshield in a dark environment at night. Of course, the display panel provided by the embodiments of the present disclosure can also be applied in other application scenarios, such as mobile phones, notebooks, tablets, computers, and the like.

[0069] Figure 1 FIG. 1 is a schematic view of a cross section of a display panel in the related art. As shown in FIG. 1, the display panel includes a plurality of display units 10, a plurality of first electrodes 20, and a plurality of second electrodes 30. Figure 1As shown, the vehicle-mounted LCD in the related art adds a layer of light control film 003 (LCF) above the backlight 001 and below the liquid crystal panel 002. The light control film 003 has a certain height, pitch and inclination angle, and has the function of shielding light at a large viewing angle. However, due to the low transmittance of the LCF film and the presence of appearance defects such as moire, diagonal lines and ghosting, etc.

[0070] Figure 2 A cross-sectional schematic diagram of a display panel provided by an embodiment of the present disclosure is shown. The display panel adopts a design without a light control film 003, and a viewing angle control unit is added above the display structure layer 004. The viewing angle control unit includes a black matrix 005 (BM), which can shield the light emission at a certain angle of the display panel, thereby realizing the control of the light emission angle of the display panel.

[0071] It can be understood that when OLED is applied to the vehicle-mounted field, it will be divided into: normal viewing angle, A+ zone, A zone and B zone. The normal viewing angle refers to the viewing angle range when the driver and the front passenger face the screen, which is the most core viewing area, approximately 0°. The normal viewing angle and the A+ zone are mainly for the driver and the front passenger, and require high image quality and brightness; while the A zone and the B zone cover a wider viewing angle range in the vehicle, to ensure that all passengers can obtain basic visibility.

[0072] The display panel in the embodiment can realize the large-angle privacy function, but causes the brightness to decay too quickly, and the brightness of the A / B zone is difficult to meet the requirements. If the structure in Figure 2 is used, the brightness of the A / B zone meets the specifications, but the normal viewing angle brightness needs to be improved, which will cause problems of power consumption, temperature rise and service life.

[0073] Alternatively, in order to improve the brightness, a lens structure can be added to the display panel in Figure 2 . The main function of the lens structure is to increase the intensity of the light at the normal viewing angle to improve its efficiency, but it is still difficult to make the brightness of the A+ / A / B zone meet the specifications, especially the A / B zone.

[0074] Based on this, the structure of the display panel is further optimized in an embodiment of the present disclosure. On the premise of improving the influence of the vehicle-mounted display panel on the user and improving the driving safety, the function, temperature rise and service life of the display panel are ensured to meet the set requirements, and the brightness of the display panel in different areas is optimized.

[0075] Figure 3 Another cross-sectional schematic diagram of a display panel provided by an embodiment of the present disclosure is shown. As shown in Figure 3As shown, the display panel provided by the embodiment of the present disclosure can be an OLED display panel, a tandem organic light emitting diode (TOLED), a quantum dot organic light emitting diode (QDOLED), a light emitting diode (LED), a micro-LED, or a liquid crystal display (LCD). The display panel comprises a substrate 100, a display structure layer 200, a first cover layer 300, and a touch structure layer 400.

[0076] As shown, Figure 3 The display structure layer 200 is located on one side of the substrate 100 and comprises a plurality of sub-pixel light transmission areas P. The display structure layer 200 and the substrate 100 form a first direction Z. Of course, other structure layers can also be arranged between the substrate 100 and the display structure layer 200, which will not be described in detail here.

[0077] As shown, Figure 3 The first cover layer 300 is located on the side of the display structure layer 200 away from the substrate 100. The touch structure layer 400 is located on the side of the first cover layer 300 away from the substrate 100 and comprises a first metal layer 410, a touch insulating layer 420, and a second metal layer 430 arranged in sequence in the direction of the substrate 100 pointing to the display structure layer 200. The first metal layer 410 has a first hollow area K1, and the orthogonal projection of the first hollow area K1 on the substrate 100 has an overlapping area with the orthogonal projection of the sub-pixel light transmission area P on the substrate 100. The second metal layer 430 has a second hollow area K2, and the orthogonal projection of the second hollow area K2 on the substrate 100 has an overlapping area with the orthogonal projection of the first hollow area K1 on the substrate 100.

[0078] In the embodiment of the present disclosure, the second metal layer 430 located on the side of the first metal layer 410 away from the substrate 100 has a second hollow area K2, the second hollow area K2 has an overlapping area with the first hollow area K1 of the first metal layer 410 in the orthographic projection of the substrate 100, and the first hollow area K1 has an overlapping area with the sub-pixel light-transmitting area P in the orthographic projection of the substrate 100, so that the light can be effectively emitted from the touch structure layer 400 to the display panel to realize normal display function. Meanwhile, the display panel provided by the embodiment of the present disclosure uses the first metal layer 410 and the second metal layer 430 in the touch structure layer 400 to shield the light emission of the display panel at a certain angle, so as to control the light emission angle of the display panel. Specifically, the overlapping relationship between the first hollow area K1 of the first metal layer 410 in the orthographic projection of the substrate 100 and the sub-pixel light-transmitting area P in the orthographic projection of the substrate 100 can be adjusted, and the overlapping relationship between the second hollow area K2 of the second metal layer 430 in the orthographic projection of the substrate 100 and the first hollow area K1 of the first metal layer 410 in the orthographic projection of the substrate 100 can be adjusted, so as to shield the light emission of the display panel at a certain angle, and to control the light emission angle of the display panel.

[0079] Please continue to refer to Figure 3 In the structure shown, the first hollow area K1 has a first boundary W1 and a second boundary W2 oppositely arranged in the second direction Y, the first boundary W1 of the first hollow area K1 has a first interval d with the sub-pixel light-transmitting area P in the orthographic projection of the substrate 100, the second boundary W2 of the first hollow area K1 has a second interval c with the sub-pixel light-transmitting area P in the orthographic projection of the substrate 100, and the second interval c is not equal to the first interval d; that is, the orthographic projection of the first hollow area K1 of the first metal layer 410 in the substrate 100 is offset and asymmetric with respect to the orthographic projection of the sub-pixel light-transmitting area P in the substrate 100 in the second direction Y. The second direction Y is perpendicular to the first direction Z.

[0080] Please continue to refer to Figure 3 In the structure shown, the second hollow area K2 has a first boundary W1' and a second boundary W2' oppositely arranged in the second direction Y, the first boundary W1' of the second hollow area K2 has a third interval d' with the sub-pixel light-transmitting area P in the orthographic projection of the substrate 100, the second boundary W2' of the second hollow area K2 has a fourth interval c' with the sub-pixel light-transmitting area P in the orthographic projection of the substrate 100, and the fourth interval c' is not equal to the third interval d'. That is, the orthographic projection of the second hollow area K2 of the second metal layer 430 in the substrate 100 is offset and asymmetric with respect to the orthographic projection of the sub-pixel light-transmitting area P in the substrate 100 in the second direction Y.

[0081] It is worth noting that when the first hollow area K1 and the second hollow area K2 are set, the third distance d' is also controlled to be greater than the first distance d, and the fourth distance c' is greater than the second distance c, so that the light can be effectively emitted from the touch structure layer 400 to the display panel to realize normal display function.

[0082] It should be noted that the display panel provided by the embodiment of the present disclosure sets the first hollow area K1 by the first metal layer 410 in the touch structure layer 400 and sets the second hollow area K2 by the second metal layer 430 to replace the black matrix, which can realize the normal display function of the display panel and realize the light shielding of the display panel. At the same time, the display panel provided by the embodiment of the present disclosure can offset the first hollow area K1 and the second hollow area K2 relative to the sub-pixel light transmission area P in the second direction Y, which can shield the light emission of the display panel at a certain angle, control the light emission angle of the display panel, and improve the brightness of the A+ / A / B area.

[0083] Accordingly, the embodiment of the present disclosure optimizes the structure of the display panel, which can improve the influence of the vehicle-mounted display panel on the user and improve the driving safety, and ensure that the function, temperature rise and service life of the display panel meet the set requirements, and optimize the brightness of the display panel in different areas.

[0084] It is worth noting that the display panel provided by the embodiment of the present disclosure is suitable for fixed privacy display panels, that is, the display panel only has a privacy mode. At this time, at least part of the privacy pixels form a sub-pixel light transmission area P corresponding to the first hollow area K1 and the second hollow area K2.

[0085] Alternatively, in some other embodiments, the display panel includes privacy pixels and shared pixels, wherein only the privacy pixels form a sub-pixel light transmission area P corresponding to the first hollow area K1 and the second hollow area K2. At this time, the display panel includes a privacy mode and a shared mode, only the privacy pixels are lit in the privacy mode, and only the shared pixels are lit or the privacy pixels and the shared pixels are lit at the same time in the shared mode.

[0086] For example, as shown in FIG. 6, the display panel 100 includes a plurality of sub-pixels 110, and each sub-pixel 110 includes a plurality of pixels 120. The display panel 100 includes a plurality of privacy pixels 120a and a plurality of shared pixels 120b. The privacy pixels 120a and the shared pixels 120b are arranged in a mixed manner. Figure 3The second interval c is greater than the first interval d, where the second interval c can range from 1 um to 30 um, and the first interval d can range from 0 um to 20 um. Meanwhile, the fourth interval c' can be greater than the third interval d', where the fourth interval c' can range from 1 um to 35 um, and the third interval d' can range from 0 um to 25 um. It can be understood that, when the display panel in the embodiments of the present disclosure is applied, the difference between the first interval d and the second interval c in the second direction Y, and the difference between the third interval d' and the fourth interval c' in the second direction Y can be set according to requirements. Meanwhile, the difference between the third interval d' and the first interval d in the second direction Y, and the difference between the fourth interval c' and the second interval c in the second direction Y can also be set according to requirements, for example, the difference between c' and c ranges from 2 um to 10 um, and the difference between d' and d ranges from 5 um to 10 um.

[0087] In the specific setting of the display panel provided in the embodiments of the present disclosure, in one embodiment of the present disclosure, the first hollow area K1 covers the orthogonal projection of the sub-pixel light-transmitting area P on the substrate 100, and the second hollow area K2 covers the orthogonal projection of the first hollow area K1 on the substrate 100. That is, the first metal layer 410 is completely hollowed out corresponding to the sub-pixel light-transmitting area P, and the second metal layer 430 is also completely hollowed out corresponding to the sub-pixel light-transmitting area P. For example, as shown in FIG. 1, the first metal layer 410 is completely hollowed out corresponding to the sub-pixel light-transmitting area P. Figure 4 It is worth noting that, Figure 3 The structure in the middle can be Figure 4 The cross-sectional view at A-A' is shown in the middle.

[0088] In another embodiment of the present disclosure, at least part of the sub-pixel light-transmitting area P and the first hollow area K1 can be set as follows: the first metal layer 410 is not completely hollowed out corresponding to the part of the first hollow area K1 of the sub-pixel light-transmitting area P in the orthogonal projection on the substrate 100; and / or, at least part of the sub-pixel light-transmitting area P and the second hollow area K2 can be set as follows: the second metal layer 430 is not completely hollowed out corresponding to the part of the second hollow area K2 of the sub-pixel light-transmitting area P in the orthogonal projection on the substrate 100. Taking the first metal layer 410 as an example, compared with the structure in the above embodiment, the first metal layer 410 in the present embodiment will be hollowed out in the first hollow area K1. Figure 3 The structure in the middle can be Figure 5 As shown in the middle, the part of the metal structure is a strip-shaped part arranged at intervals along the second direction Y, so as to finely separate the sub-pixel light-transmitting area P, optimize the light-emitting shielding of the display panel, and adjust the light.

[0089] Of course, in this embodiment, the setting of the strip needs to be based on the requirements to avoid excessively affecting the display function, and the specifics will not be elaborated further.

[0090] In one embodiment of this disclosure, the display structure layer 200 includes a plurality of pixels arranged in an array, each pixel including at least three sub-pixel light-transmitting areas P, and a second direction Y parallel to the column direction of the pixel; or, the second direction Y is parallel to the row direction of the pixel. It should be understood that... Figure 4 The example shown is illustrated with a pixel comprising three sub-pixel light-transmitting areas P, but is not limited to this. Figure 4 An example is shown with the second direction Y parallel to the pixel column direction.

[0091] When using the display panel provided in the embodiments of this disclosure, the display panel can be optimized only in the second direction Y to adjust the emitted light, or the display panel can be optimized in other directions.

[0092] Figure 6 This is a third planar schematic diagram of a portion of the film layer within a display panel provided in an embodiment of this disclosure. Figure 3 It can also be used as Figure 6 Sectional view at point A-A' Figure 7 For the corresponding Figure 6 Another plan view of the central display panel. Figure 8 for Figure 7 A schematic diagram of the cross-section at point B-B'. It is worth noting that... Figure 7 There are two sub-pixel light-transmitting areas P at point B-B'. Figure 8 The cross section shown is located along the second direction X. Figure 7 The light-transmitting area P of the sub-pixel on the right side of the middle pixel.

[0093] also, Figure 7 Each sub-pixel's light-transmitting area P can correspond to a different number of lens structures 510. For example, Figure 7 The light-transmitting area P of the sub-pixel located on the right side along the second direction X corresponds to two lens structures 510. Figure 7 Each sub-pixel's light-transmitting area P, located on the left side along the second direction X, corresponds to four lens structures 510.

[0094] like Figure 3 and Figure 6 As shown, based on the first hollowed-out area K1 having a first boundary W1 and a second boundary W2, and the second hollowed-out area K2 having a first boundary W1 and a second boundary W2, as follows: Figure 7 and Figure 8As shown, in one embodiment of the present disclosure, the first hollow area K1 also has a third boundary W3 and a fourth boundary W4 oppositely arranged in the third direction X, the third boundary W3 of the first hollow area K1 has a fifth distance e with the orthographic projection of the sub-pixel light-transmitting area P on the substrate 100, the fourth boundary W4 of the first hollow area K1 has a sixth distance f with the orthographic projection of the sub-pixel light-transmitting area P on the substrate 100, the fifth distance e is not equal to the sixth distance f; the third direction X is perpendicular to the first direction Z and the second direction Y; that is, the orthographic projection of the first hollow area K1 of the first metal layer 410 on the substrate 100 is offset and asymmetric with the orthographic projection of the sub-pixel light-transmitting area P on the substrate 100 in the third direction X.

[0095] The second hollow area K2 also has a third boundary W3' and a fourth boundary W4' oppositely arranged in the third direction X, the third boundary W3' of the second hollow area K2 has a seventh distance e' with the orthographic projection of the sub-pixel light-transmitting area P on the substrate 100, the fourth boundary W4' of the second hollow area K2 has an eighth distance f' with the orthographic projection of the sub-pixel light-transmitting area P on the substrate 100, the seventh distance e' is not equal to the eighth distance f'. That is, the orthographic projection of the second hollow area K2 of the second metal layer 430 on the substrate 100 is offset and asymmetric with the orthographic projection of the sub-pixel light-transmitting area P on the substrate 100 in the third direction X.

[0096] It is worth noting that when the first hollow area K1 and the second hollow area K2 are arranged, the seventh distance e' is greater than the fifth distance e, and the eighth distance f' is greater than the sixth distance f, so that the light can be effectively emitted from the touch structure layer 400 to the display panel to realize normal display function.

[0097] For example, the fifth distance e ranges from 0um to 20um, the sixth distance f ranges from 1um to 30um, the seventh distance e' ranges from 0um to 25um, and the eighth distance f' ranges from 1um to 35um.

[0098] It should be noted that the display panel provided by the embodiment of the present disclosure uses the first metal layer 410 and the second metal layer 430 in the touch structure layer 400 to arrange the hollow area to replace the black matrix, which can realize the normal display function of the display panel and simultaneously realize the light shielding of the display panel from two directions. At the same time, the display panel provided by the embodiment of the present disclosure is asymmetric and offset in the second direction Y and the third direction X relative to the sub-pixel light-transmitting area P by arranging the first hollow area K1 and the second hollow area K2, which can more comprehensively shield the light emission of the display panel at different angles and optimize the control of the light emission angle of the display panel.

[0099] It is worth noting that the size of the first metal layer 410 in the second direction Y and the third direction X is mainly related to the pixel layout. For example, the size of the first metal layer 410 in the third direction X is not necessarily uniform, provided that the sub-pixel light transmission area P is not occupied. The size of the first metal layer 410 in the second direction Y is wide in some places and narrow in some places, mainly related to the layout space, and as wide as possible, and the light blocking effect is better. Figure 6 For example, the size of the first metal layer 410 in the third direction X is not necessarily uniform, provided that the sub-pixel light transmission area P is not occupied. The size of the first metal layer 410 in the second direction Y is wide in some places and narrow in some places, mainly related to the layout space, and as wide as possible, and the light blocking effect is better.

[0100] It can be understood that, Figure 6 the third planar schematic diagram of the partial film layer in the display panel provided by the embodiment of the present disclosure, Figure 3 may also be used as Figure 6 the cross-sectional view at A-A' in FIG. 10, Figure 7 is another planar schematic diagram of the display panel corresponding to Figure 6 is another planar schematic diagram of the display panel corresponding to Figure 8 is Figure 7 the cross-sectional schematic diagram at B-B' in FIG. 10. It should be understood that, in order to clearly show the third planar schematic diagram of the partial film layer in the display panel provided by the embodiment of the present disclosure, Figure 7 and Figure 6 the same partial structure in the display panel is differentially identified.

[0101] In addition, it should be noted that, Figure 6 and Figure 7 the lens structure 510 is offset in the second direction X relative to the sub-pixel light transmission area P, that is, the center of the lens structure 510 in the second direction X does not coincide with the center of the sub-pixel light transmission area P in the second direction X, in order to combine the application scene and prevent the left direction light reflection from the left window affecting the driver's view of the left rearview mirror.

[0102] Of course, the lens structure 510 can also be offset in the third direction Y relative to the sub-pixel light transmission area P. As shown in FIG. 10, Figure 8 the center of the lens structure 510 is offset to the right relative to the center of the sub-pixel light transmission area P. Of course, the center of the lens structure 510 can also be offset to the left relative to the center of the sub-pixel light transmission area P in the third direction Y, and the details are not repeated here.

[0103] It is worth noting that, Figure 6 to Figure 8 in FIG. 10, the second direction Y is parallel to the column direction of the pixels, and the third direction X is parallel to the row direction of the pixels. Of course, the second direction Y can also be parallel to the row direction of the pixels, and the third direction X can be parallel to the column direction of the pixels, and the details are not repeated here.

[0104] In one embodiment of the present disclosure, as shown in FIG. 10, Figure 3As shown, the display structure layer 200 includes a driving structure layer 210, an anode 220 located on the side of the driving structure layer 210 away from the substrate 100, a pixel defining layer 230 located on the side of the anode 220 away from the substrate 100, a light emitting part 240 located on the side of the pixel defining layer 230 away from the substrate 100, and an encapsulation layer 250 located on the side of the light emitting part 240 away from the substrate 100. The pixel defining layer 230 has a plurality of pixel openings, which are light transmission areas P of sub-pixels, and the light emitting part 240 is located in the pixel openings.

[0105] In one specific embodiment, the driving structure layer 210 includes light emitting parts 240 of at least three colors, and each color of the light emitting parts 240 is located in a corresponding pixel opening; at least two colors of the light emitting parts 240 of the at least three colors are located in the same pixel column, and the remaining color of the light emitting parts 240 is located in an adjacent pixel column; and in the two adjacent pixel columns, one pixel column only contains the light emitting parts 240 of the at least two colors, and the other pixel column only contains the light emitting parts 240 of the remaining color.

[0106] For example, the driving structure layer 210 includes red light emitting parts 240, green light emitting parts 240, and blue light emitting parts 240, wherein two colors of the three light emitting parts 240 of red, green, and blue are located in the same pixel column, and the remaining color of the light emitting parts 240 is located in an adjacent pixel column. Specifically, in the two adjacent pixel columns, one pixel column only contains the light emitting parts 240 of the two colors, such as alternating arrangement of only red light emitting parts 240 and blue light emitting parts 240, and the other pixel column is composed of a plurality of green light emitting parts 240.

[0107] Figure 5 For example, the sub-pixel light transmission areas P corresponding to different light emitting parts 240 are marked with different fillers. For example, Figure 5 、 Figure 6 and Figure 7 As shown in FIGS. 1, 2, 3, and 4, in the pixel arrangement structure, each color of the sub-pixels is rectangular, wherein in one pixel column, red sub-pixels and blue sub-pixels are alternately arranged, and in the other pixel column, a plurality of green sub-pixels are arranged in the second direction Y, and the green sub-pixels have a larger size in the second direction Y, forming RealRGB. Each sub-pixel of the red sub-pixels and the blue sub-pixels corresponds to four lens structures 510, and the green sub-pixels correspond to two lens structures 510 with a larger diameter. Taking the two lens structures 510 corresponding to the green sub-pixels as an example, the two lens structures 510 are relatively uniformly distributed with respect to the green sub-pixels.

[0108] In another specific embodiment, the driving structure layer 210 includes light-emitting parts 240 of at least three colors, each color of light-emitting part 240 being located in a corresponding pixel opening; of the at least three different colored light-emitting parts 240, at least two colors of light-emitting parts 240 are located in the same pixel column, and the remaining colors of light-emitting parts 240 are located in adjacent pixel columns; and each pixel column includes at least three different colored light-emitting parts 240.

[0109] For example, the driving structure layer 210 includes a red light-emitting portion 240, a green light-emitting portion 240, and a blue light-emitting portion 240, wherein each pixel column includes three light-emitting portions 240 arranged alternately in sequence: the red light-emitting portion 240, the green light-emitting portion 240, and the blue light-emitting portion 240. However, the red light-emitting portion 240, the green light-emitting portion 240, and the blue light-emitting portion 240 belonging to two pixel columns are used in combination. Figure 9 This is a fourth planar schematic diagram of the internal film layers of the display panel provided in this embodiment of the disclosure. It is worth noting that... Figure 9 For example, the light-transmitting areas P of the sub-pixels corresponding to different light-emitting parts 240 are identified with different fillers. For example... Figure 9 As shown, in the pixel arrangement structure, each color sub-pixel is hexagonal and roughly the same size. Within each pixel column, red, green, and blue sub-pixels are arranged alternately. The multiple pixel columns arranged along the second direction Y are divided into odd-numbered and even-numbered columns. The arrangement patterns of red, green, and blue sub-pixels within the odd-numbered and even-numbered columns differ to facilitate mutual assistance between sub-pixels of different colors in adjacent pixel columns during display, effectively fulfilling the display function and forming Delta RGB.

[0110] like Figure 9 As shown, each of the red, green, and blue sub-pixels corresponds to two lens structures 510, and the two lens structures 510 are distributed relatively evenly.

[0111] In one embodiment of this disclosure, the display panel further includes a color filter layer, which includes a color resist portion corresponding to the light-emitting portion 240, and the color resist portion is located within the second cutout area K2.

[0112] For example, the color filter layer includes a red color resist portion corresponding to the red light-emitting portion 240, a green color resist portion corresponding to the green light-emitting portion 240, and a blue color resist portion corresponding to the blue light-emitting portion 240, wherein each color resist portion is located in the second cutout area K2. Of course, each color resist portion may also be located in the first cutout area K1, which will not be described in detail here.

[0113] Alternatively, the display panel provided by the embodiment of the present disclosure can also not be provided with a color film layer, that is, in another embodiment of the present disclosure, the display panel further comprises a polarizing layer, which is located on the side of the touch structure layer 400 away from the substrate 100.

[0114] In one embodiment of the present disclosure, as shown in Figure 3 The touch structure layer 400 further comprises an anti-reflection layer 440 located between the first metal layer 410 and the second metal layer 430, and comprising an oxide layer 441 and an intermediate metal layer 442 stacked in the direction of the display structure layer 200 along the substrate 100. The intermediate metal layer 442 has a third hollow area K3, and the third hollow area K3 at least partially overlaps the first hollow area K1 in the orthographic projection of the substrate 100. The second hollow area K2 at least partially overlaps the third hollow area K3 in the orthographic projection of the substrate 100. The oxide layer 441 can be an organic oxide layer.

[0115] It should be understood that Figure 3 The anti-reflection layer 440 is shown to be located between the first metal layer 410 and the touch insulating layer 420, of course, the anti-reflection layer 440 can also be provided between the second metal layer 430 and the touch insulating layer 420, and details are not described again.

[0116] It is worth noting that since the anti-reflection layer 440 comprises the intermediate metal layer 442, accordingly, the intermediate metal layer 442 needs to be provided with the third hollow area K3, and the third hollow area K3 is set to at least partially overlap the first hollow area K1 in the orthographic projection of the substrate 100. The second hollow area K2 at least partially overlaps the third hollow area K3 in the orthographic projection of the substrate 100, so as to ensure that the display panel can normally emit light.

[0117] In one specific implementation of the embodiment of the present disclosure, the third hollow area K3 in the orthographic projection of the substrate 100 can cover the first hollow area K1 in the orthographic projection of the substrate 100. The second hollow area K2 in the orthographic projection of the substrate 100 can cover the third hollow area K3 in the orthographic projection of the substrate 100.

[0118] It should be noted that the anti-reflection layer 440 in the embodiment of the present disclosure can eliminate the case of multiple reflection of light between the first metal layer 410 and the second metal layer 430 causing large-angle light leakage. Moreover, the anti-reflection layer has little effect on the normal display light of the display panel, and will not affect the display function of the display panel.

[0119] Of course, the anti-reflection layer 440 can further include at least two oxide layers 441 and at least two intermediate metal layers 442, and the oxide layers 441 and the intermediate metal layers 442 are alternately stacked. It is worth noting that the number of layers of the oxide layers 441 and the intermediate metal layers 442 should be set according to the requirements, and should not be excessively set to increase the thickness of the display panel.

[0120] In one specific embodiment of the present disclosure, as shown in Figure 3 the anti-reflection layer 440 includes at least two groups of oxide layers 441 and intermediate metal layers 442 to optimize the anti-reflection effect. For example, one oxide layer 441 is located on the side of the first metal layer 410 away from the substrate 100, and the side of the oxide layer 441 away from the substrate 100 is sequentially provided with an intermediate metal layer 442, another oxide layer 441, and another intermediate metal layer 442.

[0121] In one embodiment of the present disclosure, as shown in Figure 3 the display panel further includes a second cover layer 600 located on the side of the second metal layer 430 away from the substrate 100. When the display panel is prepared, the oxide layer 441, the intermediate metal layer 442, and the touch insulation layer 420 corresponding to the position of the light transmission area P of the sub-pixel can be etched to ensure the display effect of the display panel. Of course, the oxide layer 441 and / or the touch insulation layer 420 corresponding to the light transmission area P of the sub-pixel can also be retained, which will not be described in detail.

[0122] For example, in one specific embodiment, as shown in Figure 3 the oxide layer 441 is provided with a fourth hollow area K4, and the orthographic projection of the third hollow area K3 on the substrate 100 at least partially overlaps the orthographic projection of the fourth hollow area K4 on the substrate 100; the touch insulation layer 420 is provided with a fifth hollow area K5, and the orthographic projection of the fifth hollow area K5 on the substrate 100 at least partially overlaps the orthographic projection of the third hollow area K3 on the substrate 100; and the second cover layer 600 covers the second hollow area K2, the fifth hollow area K5, the third hollow area K3, the fourth hollow area K4, and the first hollow area K1, and the second cover layer 600 contacts the first cover layer 300.

[0123] It is worth noting that, as Figure 3As shown, taking an example that the anti-reflection layer 440 includes two layers of oxide layer 441 and two layers of intermediate metal layer 442, in the display panel provided by the embodiment of the present disclosure, the two third hollow areas K3 and the two fourth hollow areas K4 are alternately stacked along the first direction Z. Specifically, along the first direction Z, the third hollow area K3 away from the substrate 100 can cover the fourth hollow area K4 away from the substrate 100 in the orthographic projection of the substrate 100, the fourth hollow area K4 away from the substrate 100 can cover the third hollow area K3 close to the substrate 100 in the orthographic projection of the substrate 100, and the third hollow area K3 close to the substrate 100 can cover the fourth hollow area K4 close to the substrate 100 in the orthographic projection of the substrate 100.

[0124] In an embodiment of the present disclosure, as shown, Figure 3 The display panel provided by the embodiment of the present disclosure further includes a lens layer 500 located on the side of the second cover layer 600 away from the substrate 100 to improve the viewing angle characteristics and balance the light effect. The lens layer 500 includes a plurality of lens structures 510, at least one lens structure 510 has an overlapping area with the sub-pixel light-transmitting area P in the orthographic projection of the substrate 100, and the center of the orthographic projection of the lens structure 510 on the substrate 100 does not coincide with the center of the orthographic projection of the pixel sub-light-transmitting area on the substrate 100, so as to more comprehensively shield the light emission of the display panel at different angles and optimize the control of the light-emitting angle of the display panel.

[0125] It is worth noting that the orthographic projection of one or more lens structures 510 in the lens layer 500 on the substrate 100 has an overlapping area with the orthographic projection of the sub-pixel light-transmitting area P on the substrate 100.

[0126] Further, in an embodiment of the present disclosure, the orthographic projection of at least two lens structures 510 on the substrate 100 has an overlapping area with the orthographic projection of the sub-pixel light-transmitting area P on the substrate 100, and each adjacent two lens structures 510 among the at least two lens structures 510 are arranged at a distance.

[0127] It should be noted that the lens layer 500 in the embodiment of the present disclosure cooperates with the design rules of the pixel, which can further improve the brightness of the A / B area, reduce the center brightness of the structure design that the geometric center of the lens structure 510 overlaps with the sub-pixel light-transmitting area P, improve the power consumption and prolong the service life.

[0128] Wherein, the number and shape of the lens structure 510 corresponding to each sub-pixel light-transmitting area P can be the same or different, which needs to be determined according to the design requirements and the size and shape of the sub-pixel light-transmitting area P. For example, Figure 4 In an example, one sub-pixel light-transmitting area P corresponds to four lens structures 510, and another sub-pixel light-transmitting area P corresponds to two lens structures 510.

[0129] In a specific embodiment, such as Figure 3 and Figure 4 As shown, the orthographic projections of the two lens structures 510 onto the substrate 100 overlap with the orthographic projection of the sub-pixel light-transmitting area P onto the substrate 100. The orthographic projection of each lens structure 510 onto the substrate 100 is offset relative to the orthographic projection of the sub-pixel light-transmitting area P, and the spacing between adjacent lens structures 510 is set. The geometric center of the sub-pixel light-transmitting area P does not overlap with the geometric center of any of the lens structures 510. For example... Figure 3 The distance between the two lens structures 510 in the second direction is b, and the distance between the geometric center of one lens structure 510 and the geometric center of the sub-pixel light-transmitting area P in the second direction Y is a.

[0130] When setting the geometric center deviation 'a' of the light-transmitting structure 510 relative to the light-transmitting area P of the sub-pixel, the value of 'a' is at least 1 μm. The value of the spacing 'b' between two lens structures 510 corresponding to the same light-transmitting area P of the sub-pixel can be from 1 μm to 100 μm.

[0131] The spacing b between multiple lens structures 510 corresponding to the same sub-pixel light-transmitting area P can be greater than or equal to 0. For example, the spacing b between two lens structures 510 corresponding to the same sub-pixel light-transmitting area P can be 0 to 10 μm. It should be understood that... Figure 3 The center line of the spacing b can also be not on the same straight line as the center line of the light-transmitting area P of the sub-pixel.

[0132] In one embodiment of this disclosure, in a plane parallel to the plane formed by the first direction Z and the second direction Y, the cross section of the lens structure 510 is a pattern formed by connecting straight line segments and arc segments, wherein the straight line segments are located on the side of the lens structure 510 facing the substrate 100, and the arc segments convex to the side away from the substrate 100.

[0133] In one specific embodiment of this disclosure, such as Figure 10 to Figure 12 As shown, the lens structure 510 is one of a hemisphere, a semi-cylindrical shape, or a semi-ellipsoid.

[0134] For example, when lens structure 510 is used Figure 11 The lens structure 510 is a semi-cylindrical shape. Its height H in the first direction Z can be 1um to 20um, its length L in the second direction Y can be 3um to 200um, and its width W in the third direction X can be 1.5um to 100um (W = 2H).

[0135] Of course, the lens structure 510 can also be a non-standard cylinder, i.e., W≠2H.

[0136] In addition, the refractive index of the lens structure 510 can be defined as 1.501-2.5.

[0137] In one embodiment of the present disclosure, please continue to refer to Figure 3 The structure shown, the display panel further comprises a third cover layer 700 located on the side of the lens layer 500 away from the substrate 100; and the refractive index of the lens layer 500 is at least 0.1 greater than the refractive index of the third cover layer 700. Wherein, the third cover layer 700 mainly functions to protect the surface of the lens layer 500 and reduce reflection. If the refractive index of the third cover layer 700 is relatively low, it can better match the refractive index of air, reduce the reflection loss of light at the interface between the lens layer 500 and the third cover layer 700, and optimize the structural function of the display panel.

[0138] In one embodiment of the present disclosure, the refractive index of the third cover layer 700 is 1.1-1.499, so as to limit the third cover layer 700 to be made of a low refractive index material.

[0139] In one embodiment of the present disclosure, please continue to refer to Figure 3 The structure shown, the first cover layer 300 is provided with a first through hole, and the first through hole has no overlap with the orthographic projection of the sub-pixel light transmission area P on the substrate 100; the first metal layer 410 covers the side wall and the bottom wall of the first through hole to play a black matrix function and prevent light leakage; and / or, the touch insulation layer 420 is provided with a second through hole, and the second through hole has no overlap with the orthographic projection of the sub-pixel light transmission area P on the substrate 100; and the second metal layer 430 covers the side wall and the bottom wall of the second through hole to play a black matrix function and prevent light leakage.

[0140] Please continue to refer to Figure 3 The structure shown, in one embodiment of the present disclosure, the display panel further comprises a buffer layer 800 located between the display structure layer 200 and the first cover layer 300 to improve the structural performance of the display panel. In addition, the buffer layer 800 can also be located between the first cover layer 300 and the first metal layer 410, which will not be described in detail.

[0141] A specific structural design example of the display panel is provided in the embodiments of the present disclosure. The encapsulation layer 250 can include organic layers and inorganic layers alternately stacked. The first cover layer 300 is located on the inorganic layer farthest from the substrate 100 in the encapsulation layer 250, and the thickness of the first cover layer 300 in the first direction Z is 2 μm to 40 μm. The buffer layer 800 is located on the side of the first cover layer 300 away from the substrate 100, and the material is selected to be silicon nitride, and the thickness in the first direction Z is 0.1 μm to 5 μm. The first metal layer 410 is formed by a plurality of metal layers stacked, including titanium / aluminum / titanium, wherein the thickness of the first layer of titanium metal layer in the first direction Z is 0.01 μm to 0.2 μm, the thickness of the aluminum metal layer in the first direction Z is 0.05 μm to 0.9 μm, and the thickness of the second layer of titanium metal layer in the first direction Z is 0.01 μm to 0.2 μm. Notably, the first cover layer 300 and the buffer layer 800 are punched to allow the first metal layer 410 to be deposited and form a light shielding structure.

[0142] The display panel further includes an anti-reflection layer 440 located on the side of the first metal layer 410 away from the substrate 100. Specifically, the anti-reflection layer 440 includes an oxide layer 441 formed by three layers of silicon oxide and two layers of intermediate metal layer 442 formed by titanium, wherein each layer of intermediate metal layer 442 is sandwiched between two layers of oxide layer 441, and the thickness of each layer of oxide layer 441 in the first direction Z is The thickness of each layer of intermediate metal layer 442 in the first direction Z is The structure can increase the oxide / metal / oxide / metal anti-reflection stack and reduce the possibility of large viewing angle light leakage caused by reflection of light between the first metal layer 410 and the second metal layer 430.

[0143] The display panel further includes a touch insulating layer 420 located on the side of the anti-reflection layer 440 away from the substrate 100, and the material is selected to be silicon nitride, and the thickness in the first direction Z is 0.05 μm to 2 μm. The second metal layer 430 is located on the side of the touch insulating layer 420 away from the substrate 100, and can be formed by a plurality of metal layers stacked, for example, including titanium / aluminum / titanium, wherein the thickness of the first layer of titanium metal layer in the first direction Z is 0.01 μm to 0.2 μm, the thickness of the aluminum metal layer in the first direction Z is 0.05 μm to 0.9 μm, and the thickness of the second layer of titanium metal layer in the first direction Z is 0.01 μm to 0.2 μm. Notably, the touch insulating layer 420 can be punched to allow the second metal layer 430 to be deposited and form a light shielding structure.

[0144] The display panel also includes a second cover layer 600 located on the side of the second metal layer 430 away from the substrate 100, made of organic material, and the thickness of the second cover layer 600 in the first direction Z is 0.3 μm to 3 μm; a lens structure 510 located on the side of the second cover layer 600 away from the substrate 100, made of organic material, and the maximum height of the lens structure 510 in the first direction Z is 1 μm to 20 μm; and a third cover layer 700 located on the side of the second cover layer 600 away from the substrate 100 and covering the lens structure 510, made of organic material, and the thickness of the third cover layer 700 in the first direction Z is 1.2 μm to 25 μm.

[0145] In specific implementations, the display panel provided in this disclosure embodiment can be applied to various application scenarios. Depending on the application scenario, the positional relationship between the first hollow area K1 of the first metal layer 410 and the second hollow area K2 of the second metal layer 430 and the light-transmitting area P of the sub-pixel can be different. The following specific examples illustrate the display panel in conjunction with different arrangements of the pixel opening areas in the pixel limiting layer 230:

[0146] Scenario 1: Central Control Display. To prevent vertical light reflection from obstructing the driver's view on the windshield, only vertical light control is needed in this scenario; horizontal light emission does not require control. Specifically, the direction of the pixel rows in the display panel can be parallel to the direction from the driver's seat to the passenger seat. The vertical direction is the pixel column direction, and the horizontal direction is the pixel row direction.

[0147] Example 1, as Figure 4 As shown, pixels form Real RGB; Figure 4 The second direction Y is parallel to the direction of the pixel column, and the third direction X is parallel to the direction of the pixel row; the A-A' direction is parallel to the second direction Y, and the B-B' direction is parallel to the third direction X. The first boundary W1 and the second boundary W2 of the first hollow area K1 within the first metal layer 410 are... Figure 4 In the direction of A-A', that is Figure 3 In the middle, left and right directions.

[0148] Specifically, such as Figure 3 As shown, the first hollow area K1 of the first metal layer 410 has a first boundary W1 and a second boundary W2 disposed opposite to each other in the second direction Y. The orthographic projection of the first boundary W1 of the first hollow area K1 onto the substrate 100 and the orthographic projection of the sub-pixel light-transmitting area P onto the substrate 100 have a first distance d. The orthographic projection of the second boundary W2 of the first hollow area K1 onto the substrate 100 and the orthographic projection of the sub-pixel light-transmitting area P onto the substrate 100 have a second distance c. The second distance c is not equal to the first distance d.

[0149] The second hollowed-out region K2 of the second metal layer 430 has a first boundary W1' and a second boundary W2' oppositely arranged in the second direction Y, the first boundary W1' of the second hollowed-out region K2 has a third distance d' from the orthogonal projection of the sub-pixel light-transmitting region P on the substrate 100, and the second boundary W2' of the second hollowed-out region K2 has a fourth distance c' from the orthogonal projection of the sub-pixel light-transmitting region P on the substrate 100, and the fourth distance c' is not equal to the third distance d'.

[0150] In addition, in the first embodiment of the present disclosure, the second distance c is greater than the first distance d, the third distance d' is greater than the first distance d, the fourth distance c' is greater than the third distance d', and the fourth distance c' is greater than the second distance c, so that the light can be effectively emitted from the touch structure layer 400 to the display panel, and the normal display function is realized.

[0151] Please refer to Figure 10 for further description. Figure 4 In the first embodiment, the lens structure 510 is a hemisphere, and each lens structure 510 forms a circle in the second direction Y and the third direction X. As shown in Figure 3 , in the cross section of the A-A' direction, the orthogonal projection of the two lens structures 510 on the substrate 100 and the orthogonal projection of the sub-pixel light-transmitting region P on the substrate 100 have an overlapping area. As shown in Figure 3 , of the two lens structures 510 corresponding to the sub-pixel light-transmitting region P, the two lens structures 510 have a distance b in the second direction Y, and the center of the orthogonal projection of each lens structure 510 on the substrate 100 and the center of the orthogonal projection of the sub-pixel light-transmitting region P on the substrate 100 do not coincide, for example, the distance between the center of one lens structure 510 and the sub-pixel light-transmitting region P in the second direction Y is a.

[0152] Figure 13 In the cross section of the B-B' position in Figure 4 , in the first embodiment, the first metal layer 410 and the second metal layer 430 do not exist at the B-B' position, and the cross section is specifically as shown in Figure 4 . Figure 13 The first metal layer 410 and the second metal layer 430 do not exist in Figure 13 .

[0153] In the second embodiment, the difference between the second embodiment and the first embodiment is that the lens structure 510 adopts a semi-cylinder as shown in Figure 11 . As shown in Figure 14 , the lens structure 510 in the top view of the substrate 100 is different from the top view in Figure 4 . Since the cross section of the semi-cylinder at A-A' is the same as that of the hemisphere, the cross section of the structure at A-A in Figure 14 is also as shown inFigure 3 As shown.

[0154] Example 3: The only difference between Example 3 and Example 1 is that the lens structure 510 adopts... Figure 12 The semi-ellipsoid shown. Figure 15 As shown, the top view of the lens structure 510 on the substrate 100 is different. Figure 4 The top view in the diagram. Since the cross-section of the semi-ellipsoid at A-A' is approximately the same as that of the hemisphere, based on this... Figure 15 A cross-sectional diagram of the middle structure at point A-A' can also be shown as follows Figure 3 As shown.

[0155] Example 4, as Figure 16 As shown, the only difference between this embodiment four and the structure in this embodiment one is that the pixels form Delta RGB. It is worth noting that in this embodiment four, the first spacing between the light-transmitting areas P of different sub-pixels and the first boundary W1 of the first hollow area K1 is the same or different; for example, d1, d2, and d3 are the same or different. Similarly, the second spacing between the light-transmitting areas P of different sub-pixels and the second boundary W2 of the first hollow area K1 is the same or different; for example, c1, c2, and c3 are the same or different.

[0156] Furthermore, the spacing between the lens structures 510 corresponding to different sub-pixel light-transmitting areas P may be the same or different; for example, b1, b2, and b3 may be the same or different.

[0157] It is worth noting that, Figure 16 A cross-sectional diagram of the display panel at point A-A' is shown below. Figure 17 As shown, Figure 16 A cross-sectional diagram of the display panel at point B-B' is shown below. Figure 18 As shown.

[0158] Example 5, please refer to Figure 16 refer to Figure 19 The structure shown in Embodiment 5 differs from that in Embodiment 4 only in that the lens structure 510 within the lens layer 500 is a semi-cylinder. For example... Figure 19 As shown, each lens structure 510 has a rectangular top view in the plane formed by the second direction Y and the third direction X. Each sub-pixel corresponds to two semi-cylindrical lens structures 510, which are spaced apart along the second direction Y. The long side of each lens structure 510 extends along the third direction X. It should be understood that the two lens structures 510 corresponding to each sub-pixel are distributed relatively evenly.

[0159] Example 6, please refer to Figure 16 refer to Figure 20The structure shown in this embodiment six and the structure in the fourth embodiment are only different in that the lens structure 510 in the lens layer 500 is a semi-elliptical sphere. As shown in Figure 20 Each lens structure 510 forms an elliptical shape in a plan view in the second direction Y and the third direction X, two semi-elliptical lens structures 510 corresponding to each sub-pixel are spaced apart along the second direction Y, and the long axis of each lens structure 510 extends along the third direction X. It should be understood that the two lens structures 510 corresponding to each sub-pixel are more evenly distributed.

[0160] Embodiment seven, please combine Figure 4 Reference Figure 21 The structure shown in this embodiment seven and the structure in the first embodiment are only different in that the lens layer 500 is not provided in this embodiment seven. Figure 22 To Figure 21 The cross-sectional view at A-A' in FIG. 1C; Figure 23 The cross-sectional view at B-B' in FIG. 1C. Figure 21

[0161] Embodiment eight, please combine Figure 9 Reference Figure 24 The structure shown in this embodiment eight and the structure in the seventh embodiment are only different in that the pixel forms a Delta RGB.

[0162] Scene two, instrument display, which needs to prevent light reflection in the vertical direction from affecting the driver's view through the front windshield; prevent light reflection in the left direction from affecting the driver's view of the left side mirror (the driver is on the left side); specifically, the direction of the pixel row in the display panel can be parallel to the direction from the main driver to the co-driver. In this scene two, light control is needed in the vertical direction, and light emission to the left side in the horizontal direction needs to be controlled, and light emission to the right side does not need to be controlled.

[0163] Embodiment nine, as Figure 3 , Figure 6 , Figure 7 and Figure 25 shown, wherein Figure 3 may be Figure 6 and Figure 7 the cross-sectional view at A-A' in FIG. 1C, Figure 25 Figure 6 and Figure 7 ​​The cross-sectional schematic diagram at point B-B' shows that the difference between the display panel in Embodiment Nine and Embodiment One is that the first hollow area K1 of the first metal layer 410 not only has a first boundary W1 and a second boundary W2 that are relatively arranged in the second direction Y, but also has a third boundary W3 and a fourth boundary W4 that are relatively arranged in the third direction X. Similarly, the second hollow area K2 of the second metal layer 430 not only has a first boundary W1' and a second boundary W2' that are relatively arranged in the second direction Y, but also has a third boundary W3' and a fourth boundary W4' that are relatively arranged in the third direction X, so as to adjust the light of the display panel in the third direction X.

[0164] Example 10, as follows Figure 26 and Figure 27 As shown, the difference between Embodiment 10 and Embodiment 9 lies only in that the pixels form Delta RGB, and the lens structure 510 within the lens layer 500 is a semi-ellipsoid. It should be understood that this is a schematic diagram of a third planar representation of the internal film layers of the display panel provided in this embodiment of the present disclosure, to clearly illustrate this third planar representation. Figure 26 and Figure 27 The differences in the local structures within the same display panel are marked. Figure 26 and Figure 27 The center of the central lens structure 510 is offset to the right relative to the center of the sub-pixel light-transmitting area P, in order to prevent light emitted from the left side from reflecting onto the left window and affecting the driver's view of the left rearview mirror, depending on the application scenario. Of course, the center of the lens structure 510 can also be offset to the left relative to the center of the sub-pixel light-transmitting area P in the third direction Y, which will not be elaborated further.

[0165] The first hollow area K1 of the first metal layer 410 not only has a first boundary W1 and a second boundary W2 that are relatively arranged in the second direction Y, but also has a third boundary W3 and a fourth boundary W4 that are relatively arranged in the third direction X. Similarly, the second hollow area K2 of the second metal layer 430 not only has a first boundary W1' and a second boundary W2' that are relatively arranged in the second direction Y, but also has a third boundary W3' and a fourth boundary W4' that are relatively arranged in the third direction X, so as to adjust the light of the display panel in the third direction X.

[0166] Furthermore, the display panel provided in this embodiment can also be applied to scenario three (passenger display). Specifically, it prevents light emanating from the right side in the horizontal direction from reflecting onto the side windshield and affecting the driver's vision, and prevents light emanating from the left side in the horizontal direction from entering the driver's vision, causing driver distraction and affecting driving safety (when the driver is on the left). Specifically, the direction of the pixel rows in the display panel can be parallel to the direction from the driver's seat to the passenger seat; light control is required in the horizontal direction, while vertical light emission does not require control. It is worth noting that, at this time, compared to... Figure 6In the middle structure, only the first metal layer 410 located on both sides of the sub-pixel light-transmitting area P in the third direction X needs to be reserved. Similarly, the second metal layer 430 is also located on both sides of the sub-pixel light-transmitting area P in the third direction X.

[0167] The display device provided by the embodiments of the present disclosure includes the display panel in any of the technical solutions.

[0168] It should be noted that, in the display device, the display panel uses the first metal layer 410 in the touch control structure layer 400 to set the first hollow area K1 and uses the second metal layer 430 to set the second hollow area K2 to replace the black matrix, so that the normal display function of the display panel can be realized, and the light emission of the display panel can be shielded. Meanwhile, the display panel provided by the embodiments of the present disclosure can shield the light emission of the display panel at a certain angle by setting the first hollow area K1 and the second hollow area K2 to be asymmetric and offset relative to the sub-pixel light-transmitting area P in the second direction Y, so that the light emission angle of the display panel can be controlled, and the brightness of the A+ / A / B area can be improved.

[0169] Accordingly, the embodiments of the present disclosure optimize the structure of the display panel in the display device, so that the function, temperature rise, and service life of the display panel can meet the set requirements on the premise of improving the influence of the vehicle-mounted display panel on the user and improving the driving safety, and the brightness of the display panel in different areas is optimized.

[0170] It should be noted that although the steps of the method for manufacturing the display panel in the present disclosure are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in this specific order, or that all the steps shown must be performed to achieve the desired result. In addition or alternatively, some steps can be omitted, a plurality of steps can be combined into one step, and / or one step can be divided into a plurality of steps, etc.

[0171] Other embodiments of the present disclosure will be apparent to those skilled in the art upon consideration of the specification and practice of the present disclosure. The present disclosure is intended to cover any variations, uses, or adaptations of the present disclosure following the general principles thereof and including modifications and equivalents of the present disclosure. The specification and examples are to be regarded as illustrative only, and the true scope and spirit of the present disclosure are indicated by the appended claims.
