DETAILED DESCRIPTION

[0056] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0057] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, they do not represent any order, quantity or importance, but are only used to distinguish different components. These terms are only used to distinguish one element from another element. For example, without departing from the scope of the present application, the first element may be referred to as the second element, and similarly, the second element may be referred to as the first element. "Including" or "comprising" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0058] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0059] Organic Light-Emitting Diode (OLED) display devices have been listed as a display technology with great development prospects due to their advantages such as thinness, lightness, wide viewing angle, active light emission, continuously adjustable light emission color, low cost, fast response speed, low energy consumption, low driving voltage, wide operating temperature range, simple production process, high light emission efficiency and flexible display.

[0060] In the related art, in addition to the display function, the light-transmitting display panel also allows users to see the object behind the light-transmitting display panel through at least part of the light-transmitting display panel. The light-transmitting display panel has a wide range of applications in various fields, such as traffic windows, museum display cabinets, shopping mall windows, and augmented reality (AR).

[0061] However, in order to ensure the light transmittance of the light-transmitting display panel, the display area will be reduced, resulting in a lower pixel density (Pixels Per Inch, abbreviated as PPI) of the light-transmitting display panel, which will cause the brightness and visibility of the light-transmitting display panel to deteriorate, thereby affecting the display effect of the light-transmitting display panel and reducing the life of the light-transmitting display panel. In addition, in order to ensure the light transmittance of the light-transmitting display panel, the polarizer will be removed, which will further increase the reflectivity of the light-transmitting display panel. When the external ambient light is bright, the light-transmitting display panel has a strong reflection, resulting in a lower ambient contrast of the light-transmitting display panel, poor visibility of the light-transmitting display panel, and further deterioration of the display effect.

[0062] To solve the above problems, the embodiments of the present application provide a display panel and a display device, in which the auxiliary pixels are located on the side of the conductive trace away from the substrate. In this way, when the display panel is in a display state, the auxiliary pixels can emit light to display the picture. For example, the user can adjust the brightness of the auxiliary pixels according to the intensity of the ambient light, and can realize the display function when the external light intensity is strong, so that the external objects will not be reflected and imaged, thereby reducing the reflectivity of the display panel and increasing the ambient light contrast of the display panel, thereby enhancing the readability of the display panel. In addition, the brightness of the display panel can be improved, the aperture ratio can be increased, thereby improving the display effect of the display panel and the display device, and prolonging the life of the display panel and the display device.

[0063] For a better understanding, some explanations are given before going into detail:

[0064] Sub-pixels: Sub-pixels are composed of small grids that display images. These small grids have a clear position and assigned color values, and the clear position is determined by the pixel arrangement, and the assigned color value is determined by the pixel circuit. The color and position of these small grids determine the appearance of the displayed image.

[0065] Resolution: Display resolution refers to the precision of the displayed image, specifically, how many sub-pixels the display can display. For example, common resolutions are HD: 720*1280, FHD: 1080*1920, QHD: 1440*2560, and UHD (2K\4K): 2160*3840. Taking FHD as an example, it means that there are 1080 R sub-pixels, 1080 G sub-pixels, and 1080 B sub-pixels in one direction, and 1920 R sub-pixels (i.e., red sub-pixels), 1920 G sub-pixels (i.e., green sub-pixels), and 1920 B sub-pixels (i.e., blue sub-pixels) in the other direction.

[0066] PPI (Pixels Per Inch): Also known as pixel density, it indicates the number of pixels in one inch. For example, FHD resolution and 5-inch size have 441 PPI. Therefore, it can be considered that under the premise that the size of the display is certain, the higher the resolution, the higher the PPI.

[0067] It should be pointed out that those skilled in the art should know that based on the pixel arrangement structure of the present application, each sub-pixel should be distributed as evenly as possible.

[0068] The following will be combined Figure 1-Figure 19 The display device provided in the embodiment of the present application is described.

[0069] The present application provides a display device, which includes a display panel. The display device can be an electronic paper, a mobile phone, a tablet computer, a television, a display, a laptop, a digital photo frame, a smart bracelet, a smart watch, a super personal computer, a navigator, a wireless device, a personal digital assistant (PDA), a handheld or portable computer, a GPS receiver / navigator, a camera, an MP4 video player, a camera, a game console, a clock, a calculator, a television monitor, a computer monitor, a car display (e.g., an odometer display, etc.), a cockpit controller and / or display, a display of a camera view (e.g., a display of a rear-view camera in a vehicle), an electronic billboard or sign, a projector, and other mobile or fixed terminals.

[0070] Exemplarily, the display panel can be an organic light-emitting diode (OLED) display panel, a micro organic light-emitting diode (Micro OLED) display panel, a light emitting diode (LED) display panel, a quantum dot light emitting diode (QLED) display panel, a mini light emitting diode (Mini LED) display panel, a micro light emitting diode (Micro Light Emitting Diode) display panel, or a liquid crystal display (LCD) display panel, etc.

[0071] The display panel provided in the embodiments of the present application is described below.

[0072] The display panel provided in the embodiment of the present application may include a display area 10a ( Figure 1 A partial display area 10a) and a non-display area are shown. The display area 10a can be used to display a picture, and the non-display area can be arranged adjacent to the display area 10a. The non-display area can be located on at least one side of the display area 10a. For example, the non-display area can be arranged around the periphery of the display area 10a, and the non-display area can form a "black border" surrounding the periphery of the display area 10a. Specifically, the display area 10a can be a rectangle. Of course, the shape and arrangement of the display area 10a and the non-display area include but are not limited to the above-mentioned examples. For example, when the display panel is used for a wearable device worn on a user, the display area 10a can have a circular shape like a watch. When the display substrate is used for display on a vehicle, the display area 10a and the non-display area can be in a circular, polygonal or other shape, for example.

[0073] In some embodiments, see Figure 1 The display area 10a may include a pixel area 10c and a light-transmitting area 10b. At least part of the pixel area 10c may be arranged around the periphery of the light-transmitting area 10b. The pixel area 10c may include a plurality of first pixel areas 11c and a plurality of second pixel areas 12c. The plurality of first pixel areas 11c may be arranged at intervals, and a second pixel area 12c may be arranged between each two adjacent first pixel areas 11c. The display panel of the light-transmitting area 10b may transmit light, so that the user may observe the object behind the display panel through the display panel, or the device behind the display panel may be illuminated by the display panel of the light-transmitting area 10b. In addition, at least part of the display panel of the first pixel area 11c and at least part of the display panel of the second pixel area 12c may not be light-transmitting.

[0074] Exemplarily, there may be a plurality of light-transmitting regions 10 b , and the plurality of light-transmitting regions 10 b may be arranged at intervals.

[0075] For example, the distribution area and proportion of the light-transmitting area 10b in the display area 10a can be set according to needs, and the embodiment of the present application does not limit this.

[0076] In some embodiments, the display panel may include a substrate, and the substrate may provide support for the remaining structural layers that are subsequently arranged. In some examples, the substrate may be a rigid substrate, for example, the material of the substrate may be glass. In some other examples, the substrate may be a flexible substrate, and the material of the substrate may include at least one of polyimide (PI), polyethylene terephthalate, polyethylene naphthalate, polyethylene, polyacrylate, polyetherimide, polycarbonate, polyarylate, and polyethersulfone.

[0077] The first pixel region 11 c and the pixel group 110 provided in the embodiment of the present application are described below.

[0078] In some embodiments, see Figure 3 The display panel may include a plurality of pixel groups 110, and each of the plurality of pixel groups 110 may be located on a substrate. One pixel group 110 may be located in one first pixel region 11c.

[0079] In some embodiments, see Figure 3 and Fig.17 , the display panel may have a first direction X, a second direction Y and a third direction Z, and the first direction X, the second direction Y and the third direction Z are all different. The first direction X and the second direction Y may be any two different directions parallel to the display panel, and the third direction Z may be any direction intersecting with a plane parallel to the display panel. For example, the first direction X, the second direction Y and the third direction Z may be perpendicular to each other. Exemplarily, the first direction X may be the width direction of the display panel, the second direction Y may be the length direction of the display panel, and the third direction Z may be the thickness direction of the display panel. The length, width and thickness in the embodiments of the present application are merely for the convenience of description and do not imply any limitation on the size. For example, the width may be greater than, equal to or less than the length.

[0080] In some embodiments, see Figure 3 , the plurality of pixel groups 110 may be arranged in rows along the first direction X, and in columns along the second direction Y. For example, the plurality of pixel groups 110 may be arranged in an array, thereby alleviating the jaggedness and discontinuity of the image of the display panel.

[0081] In some examples, the plurality of pixel groups 110 form a plurality of rows, wherein the odd-numbered pixel groups 110 and the even-numbered pixel groups 110 are arranged relative to each other in the second direction Y. Specifically, each pixel group 110 in the odd-numbered pixel groups 110 is arranged relative to each pixel group 110 in the adjacent even-numbered pixel groups 110. In other examples, the plurality of pixel groups 110 form a plurality of rows, wherein the odd-numbered pixel groups 110 and the even-numbered pixel groups 110 are arranged in a staggered manner in the second direction Y. Specifically, the pixel groups 110 in the odd-numbered pixel groups 110 are located between two pixel groups 110 in the adjacent even-numbered pixel groups 110.

[0082] In some embodiments, see Figure 3 and Figure 6In the same first pixel region 11c, the pixel group 110 may include a plurality of sub-pixels, and the plurality of sub-pixels may include a first sub-pixel 111, a second sub-pixel 112, and a third sub-pixel 113 having different luminous colors. The first pixel region 11c may include a first sub-pixel region 101c, a second sub-pixel region 102c, and a third sub-pixel region 103c. The first sub-pixel 111 may be located in the first sub-pixel region 101c, the second sub-pixel 112 may be located in the second sub-pixel region 102c, and the third sub-pixel 113 may be located in the third sub-pixel region 103c.

[0083] Among them, the pixel group 110 refers to: the smallest repeating unit repeatedly arranged in the display panel. The first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel 113 can be one of a red sub-pixel, a blue sub-pixel and a green sub-pixel, respectively. Of course, in some other embodiments, the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 can also be sub-pixels that emit light of other colors besides red, green and blue, for example, white or yellow, which is not limited in the embodiments of the present application. A sub-pixel is characterized as the smallest unit for emitting light (for example, the smallest addressable unit of a display panel).

[0084] In some examples, the shapes of the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 are different. In other examples, at least two of the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 are the same in shape.

[0085] It should be noted that the display panel provided in the embodiment of the present application can adjust the graphic sizes of the first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel 113 according to actual needs, so as to facilitate the adjustment of color deviation.

[0086] In some embodiments, see Figure 4 and Figure 5 In the same first pixel region 11c, at least one sub-pixel may include a third sidewall 1143 ( Figure 5 ), the shape of the orthographic projection of the third side wall 1143 on the substrate is adapted to the shape of the edge of the first pixel region 11c, which is conducive to reducing the distance between the sub-pixel and the edge of the first pixel region 11c, so that the sub-pixels are compactly arranged, and the space in the first pixel region 11c is fully utilized, thereby improving the aperture ratio. For example, the shape of the orthographic projection of the third side wall 1143 of each sub-pixel in the same first pixel region 11c on the substrate is adapted to the shape of the edge of the first pixel region 11c, so that the aperture ratio can be further improved.

[0087] In some examples, the shape of the first pixel region 11c may be circular or elliptical, and correspondingly, the third sidewall 1143 ( Figure 5 ) is an arc in shape of its orthographic projection on the substrate, or the shape of the first pixel region 11c is a polygon, and the angle between two adjacent sides of the polygon is greater than 90°, so that the edge transition of the first pixel region 11c is smoother and more rounded. Taking the shape of the first pixel region 11c as a polygon as an example, such a setting can avoid the angle between two adjacent sides being too sharp as an acute angle or a right angle, so that the area at the angle of the polygon can be large enough, that is, the area of ​​the first pixel region 11c is large enough, which is conducive to improving the aperture ratio of the display panel. In addition, in the embodiment of using a mask plate to evaporate the sub-pixel, the mask plate includes a plate body, and the plate body has an opening. During the evaporation process, the opening is set corresponding to the sub-pixel area (any one of the first sub-pixel area 101c, the second sub-pixel area 102c, and the third sub-pixel area 103c) in the first pixel region 11c. The mask may include a first mask for evaporating each first sub-pixel 111, a second mask for evaporating each second sub-pixel 112, and a third mask for evaporating each third sub-pixel 113. During the evaporation process, the opening of the first mask is set corresponding to the first sub-pixel area 101c and the shape is adapted, the opening of the second mask is set corresponding to the second sub-pixel area 102c and the shape is adapted, and the opening of the third mask is set corresponding to the third sub-pixel area 103c and the shape is adapted. The angle between two adjacent sides of the polygonal first pixel area 11c is set to be greater than 90°, or the first pixel area 11c is set to be circular or elliptical. Correspondingly, the opening of the mask needs to be set large enough and, when the sub-pixel is evaporated through the larger opening of the mask, it is beneficial to increase the area of ​​the evaporated sub-pixel, so as to improve the aperture ratio of the display panel.

[0088] It is understandable that, since the second pixel area 12c is provided and the auxiliary pixel 130 is provided in the second pixel area 12c, the aperture ratio of the display panel can be improved. In the related art, the second pixel area 12c and the auxiliary pixel 130 are not provided. In order to achieve the aperture ratio of the display panel of the embodiment of the present application, it is necessary to set the first pixel area 11c larger and the light-transmitting area 10b smaller, resulting in a decrease in the light transmittance of the display panel. Therefore, the embodiment of the present application is conducive to improving the aperture ratio of the display panel by providing the second pixel area 12c and the auxiliary pixel 130, while ensuring that the display panel has a high transmittance.

[0089] For example, the shape of the first pixel region 11 c is a polygon, and the angle between two adjacent sides of the polygon may be 95°, 100°, 105°, 110°, or any value greater than 90°.

[0090] It should be noted that, in a polygon, two adjacent sides may be straight sides, or two adjacent sides may be arc sides, or one of the two adjacent sides may be a straight side and the other may be an arc side. When one of the two adjacent sides is a straight side and the other is an arc side, the angle between the two adjacent sides is the angle between the tangent of the connection point where the arc side and the straight side are connected and the straight side. If the two adjacent sides are both arc sides, the angle between the two adjacent sides is the angle between the tangents at the connection point of the two arc sides.

[0091] It can be realized that the polygon of the first pixel region 11c can be a dodecagon. For example, the polygon can be a regular dodecagon or a non-regular dodecagon. For example, see Figure 6 , six regular hexagons A1, A2, A5, A7, A6, A3 can be connected end to end in sequence, and the six regular hexagons A1, A2, A5, A7, A6, A3 can be arranged around the periphery of the seventh regular hexagon A4, so as to achieve the most densely packed arrangement of seven regular hexagons, and then, the vertices of the shapes of the seven hexagonal stacking arrangements are connected to form a dodecagon as the shape of the first pixel area 11c, so that the area at the angle of the dodecagon can be further made large enough, so that the area of ​​the first pixel area 11c is large enough, and the aperture ratio of the display panel is further improved. Among them, the seven regular hexagons are all virtual graphics.

[0092] In the embodiment of using seven regular hexagons in the closest packing arrangement to obtain the first pixel area 11c of dodecagonal shape, see Figure 6 , the seven regular hexagons can be regular hexagon A1, regular hexagon A2, regular hexagon A3, regular hexagon A4, regular hexagon A5, regular hexagon A6, and regular hexagon A7. Figure 7 , the vertices of the dodecagon may include vertex B1, vertex B2, vertex B3, vertex B4, vertex B5, vertex B6, vertex B7, vertex B8, vertex B9, vertex B10, vertex B11, and vertex B12. Figure 8 , the vertices of any regular hexagon may include vertex C1, vertex C2, vertex C3, vertex C4, vertex C5, and vertex C6.

[0093] The shape of the first pixel region 11c is circular, elliptical or the above polygonal ( Figure 5 ) embodiment, since the edge of the first pixel region 11c is more rounded, the third sidewalls 1143 ( Figure 5) The shape enclosed by the anode is also more rounded, so that the white light mixing effect is better and the tailing phenomenon can be alleviated. For example, the shape of the edge of the anode corresponding to the pixel group 110 can be set to match the shape of the first pixel area 11c. The shape of the edge of the anode is relatively rounded, which is conducive to reducing the diffraction effect of the anode, thereby alleviating the haze of the display panel and improving the display effect of the display panel.

[0094] In some embodiments, see Figure 5 In the same pixel group 110, the side walls of the first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel 113 adjacent to each other are the fourth side walls 1144, and the shape of the orthographic projection of the fourth side wall 1144 on the substrate is a straight line. In this way, it is helpful to reduce the distance between two adjacent sub-pixels, so that multiple sub-pixels are compactly arranged, and the space in the first pixel area 11c is fully utilized, thereby improving the aperture ratio.

[0095] The first sub-pixel region 101c, the second sub-pixel region 102c and the third sub-pixel region 103c provided in the embodiment of the present application are described below.

[0096] The following description is made by taking an example where the first sub-pixel 111 is a blue sub-pixel, the second sub-pixel 112 is a green sub-pixel, and the third sub-pixel 113 is a red sub-pixel.

[0097] In the same first pixel region 11 c , areas of any two of the first sub-pixel region 101 c , the second sub-pixel region 102 c , and the third sub-pixel region 103 c may be the same or different.

[0098] Exemplarily, in the same first pixel region 11c, the area of ​​the first sub-pixel region 101c is larger than the areas of the second sub-pixel region 102c and the third sub-pixel region. For example, the areas of the first sub-pixel region 101c, the second sub-pixel region 102c and the third sub-pixel region 103c can be reduced in sequence, which is conducive to achieving a sequential reduction in the areas of the blue sub-pixel, the green sub-pixel and the red sub-pixel, so that the area of ​​the blue sub-pixel is larger (the lifespan of the blue sub-pixel is lower than that of sub-pixels of other colors), which can help to increase the lifespan of the blue sub-pixel.

[0099] Figure 3-Figure 6 A first arrangement of the first sub-pixel region 101c, the second sub-pixel region 102c and the third sub-pixel region 103c is shown. Figure 6 In the same first pixel area 11c, the second sub-pixel area 102c can be located on the same side of the first sub-pixel area 101c and the third sub-pixel area 103c. At this time, the green sub-pixel can be located on the same side of the blue sub-pixel and the red sub-pixel, so that the white light mixing effect of the pixel group 110 is better, and there is no protruding area at the edge, the overall shape is smoother, and the light spot is more uniform.

[0100] For example, see Figure 6 There is a first boundary line 171 between the second sub-pixel area 102c and the first sub-pixel area 101c and the third sub-pixel area 103c. The first boundary line 171 intersects at the vertex B1 and the vertex B8 of the dodecagon ( Figure 7 ), that is, the first dividing line 171 intersects at the vertex C1 of the regular hexagon A3 and the vertex C5 of the regular hexagon A5. A second dividing line 172 is provided between the first sub-pixel area 101c and the third sub-pixel area 103c. The second dividing line 172 is perpendicular to the first dividing line 171. The second dividing line 172 intersects with the first dividing line 171 at the first intersection. The ratio of the distance between the first intersection and the vertex B1 to the extension length of the first dividing line 171 is in the range of 1 / 2-2 / 3. For example, the second dividing line 172 intersects at the midpoint of the line connecting the vertex C1 and the vertex C6 of the regular hexagon A7, at the midpoint of the line connecting the vertex C2 and the vertex C3 of the regular hexagon A7, and at the first dividing line 171 and the side of the dodecagon. In this way, the division difficulty of the first dividing line 171 and the second dividing line 172 is relatively low. For example, the second sub-pixel region 102c may be located on the left side of the first pixel region 11c, the first sub-pixel region 101c and the third sub-pixel region 103c may be located on the right side of the first pixel region 11c, and the first sub-pixel region 101c may be located on the upper side of the third sub-pixel region 103c.

[0101] It should be noted that the “dividing line” (eg, the first dividing line 171 ) in the embodiment of the present application is a virtual straight line, and different sub-pixel areas can be distinguished by the dividing line.

[0102] Figure 9-12 A second arrangement of the first sub-pixel region 101c, the second sub-pixel region 102c and the third sub-pixel region 103c is shown. Fig.12 In the same first pixel area 11c, the second sub-pixel area 102c can be located between the first sub-pixel area 101c and the third sub-pixel area 103c. At this time, the green sub-pixel can be located between the blue sub-pixel and the red sub-pixel. At this time, the arrangement of the green sub-pixel, the blue sub-pixel and the red sub-pixel is relatively uniform and regular. When the auxiliary pixel 130 does not need to be displayed, part of the outer edge of the display panel of the display area 10a is the blue sub-pixel and the red sub-pixel, and the human eye is not sensitive to the blue sub-pixel and the red sub-pixel, so that the color edge effect of the display panel of the display area 10a is better.

[0103] For example, see Fig.12, there is a third dividing line 173 between the first sub-pixel area 101c and the second sub-pixel area 102c, and the third dividing line 173 may intersect at the side BB1 ​​of the regular hexagon A3 and the side BB2 of the regular hexagon A5, the side BB1 ​​is the side where the vertices C1 and C6 of the regular hexagon A3 are located, and the side BB2 is the side where the vertices C5 and C6 of the regular hexagon A5 are located. For example, the third dividing line 173 intersects at the vertex B1 and the vertex B8 of the dodecagon (i.e., the vertex C1 of the regular hexagon A3 and the vertex C5 of the regular hexagon A5) ( Fig.12 ). A fourth dividing line 174 is provided between the second sub-pixel area 102c and the third sub-pixel area 103c. The fourth dividing line 174 can be compared to the side BB3 of the regular hexagon A3 and the side BB4 of the regular hexagon A5. The side BB3 is the side where the vertices C2 and C3 of the regular hexagon A3 are located, and the side BB4 is the side where the vertices C3 and C4 of the regular hexagon A5 are located. For example, the fourth dividing line 174 intersects at the vertex C1 of the regular hexagon A6 and the vertex C1 of the regular hexagon A7, and intersects with the side of the dodecagon. For example, the first sub-pixel area 101c can be located on the left side of the first pixel area 11c, the third sub-pixel area 103c can be located on the right side of the first pixel area 11c, and the second sub-pixel area 102c can be located between the first sub-pixel area 101c and the third sub-pixel area 103c.

[0104] Figure 9-12 FIG. 1 shows a third arrangement of the first sub-pixel region 101c, the second sub-pixel region 102c and the third sub-pixel region 103c. Fig.16 In the same first pixel region 11c, the first sub-pixel region 101c can be located between the second sub-pixel region 102c and the third sub-pixel region 103c. In this way, since the first sub-pixel region 101c is arranged close to the middle of the first pixel region 11c, and the length of the middle position of the first pixel region 11c (for example, along the first direction X) is large, even if the width of the first sub-pixel region 101c (for example, along the second direction Y) is set to be narrow, the area of ​​the first sub-pixel region 101c can be made larger, so that a larger blue area can be arranged in the first sub-pixel region 101c. Sub-pixels are beneficial to improving the life of the blue sub-pixel. In addition, since the width of the first sub-pixel area 101c is relatively small, the widths of the second sub-pixel area 102c and the third sub-pixel area 103c located on both sides of the first sub-pixel area 101c are relatively large, so that the areas of the second sub-pixel area 102c and the third sub-pixel area 103c are relatively large, thereby alleviating the adverse effects of the blue sub-pixel occupying too large a width of the first pixel area 11c on the settings of the green sub-pixel and the red sub-pixel, thereby helping to improve the aperture ratio of the display panel and achieve a better white light mixing effect.

[0105] For example, see Fig.16, there is a fifth dividing line 175 between the first sub-pixel area 101c and the second sub-pixel area 102c, and the fifth dividing line 175 may intersect at the side BB1 ​​of the regular hexagon A3 and the side BB2 of the regular hexagon A5, the side BB1 ​​is the side where the vertices C1 and C6 of the regular hexagon A3 are located, and the side BB2 is the side where the vertices C5 and C6 of the regular hexagon A5 are located. For example, the fifth dividing line 175 intersects at one-fourth of the line connecting the vertices C1 and C6 of the regular hexagon A3 (and the intersection is closer to the vertex C6 of the regular hexagon A3), intersects at one-fourth of the line connecting the vertices C1 and C6 of the regular hexagon A5 (and the intersection is closer to the vertex C6 of the regular hexagon A5), and intersects at the side of the dodecagon. There is a sixth dividing line 176 between the first sub-pixel area 101c and the third sub-pixel area 103c. The sixth dividing line 176 can be compared to the side BB3 of the regular hexagon A3 and the side BB4 of the regular hexagon A5. The side BB3 is the side where the vertices C2 and C3 of the regular hexagon A3 are located, and the side BB4 is the side where the vertices C3 and C4 of the regular hexagon A5 are located. For example, the sixth dividing line 176 intersects at one-fourth of the line connecting the vertices C2 and C3 of the regular hexagon A3 (and the intersection is closer to the vertex C3 of the regular hexagon A3), intersects at one-fourth of the line connecting the vertices C2 and C3 of the regular hexagon A5 (and the intersection is closer to the vertex C3 of the regular hexagon A5), and intersects at the side of the dodecagon. For example, the second sub-pixel region 102c may be located on the left side of the first pixel region 11c, the third sub-pixel region 103c may be located on the right side of the first pixel region 11c, and the first sub-pixel region 101c is located between the second sub-pixel region 102c and the third sub-pixel region 103c.

[0106] The conductive trace 120 and the auxiliary pixel 130 provided in the embodiment of the present application are described below.

[0107] See also Figure 17-Figure 19 The display panel may include a conductive trace 120, and the orthographic projection of the conductive trace 120 on the substrate overlaps with the orthographic projection of the second pixel region 12c on the substrate. For example, the conductive trace 120 may be located in the second pixel region 12c. Exemplarily, the conductive trace 120 may also extend into the first pixel region 11c. The conductive trace 120 may be used to electrically connect every two adjacent pixel groups 110, and may also control the light emission of the pixel group 110.

[0108] See also Fig.19 In the same second pixel region 12c, the conductive trace 120 may include a plurality of sub-conductive traces 121, and any two of the plurality of sub-conductive traces 121 may be located in the same layer, or may be located in different layers.

[0109] Exemplarily, the material of the conductive trace 120 may include any one or more metals such as titanium, silver, copper, aluminum, molybdenum, or alloys, or conductive oxides (such as indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), and aluminum zinc oxide (AZO).

[0110] In some embodiments, a planarization layer 140 is disposed on the side of the conductive trace 120 facing away from the substrate, thereby facilitating improving the flatness of subsequent film layers on the planarization layer 140 .

[0111] Exemplarily, the side of the planarization layer 140 facing away from the substrate may be flat, thereby better improving the flatness of subsequent film layers.

[0112] In some embodiments, see Fig.17 and Fig.19 , in the second pixel area 12c, the first surface 1221 is the surface of the film layer farthest from the substrate when the planarization layer 140 has not been set on the conductive trace 120, and its surface morphology is affected by the conductive trace 120. The orthographic projection of each sub-conductive trace 121 on the substrate is a third orthographic projection, and there may be a gap between at least part of the two adjacent third orthographic projections. Due to the existence of this gap, there is a gap between the corresponding two adjacent sub-conductive traces 121 along the extension direction of the substrate, resulting in a more serious diffraction phenomenon in the second pixel area 12c, which deteriorates the display effect of the display panel. In addition, each sub-conductive trace 121 also makes the flatness of the first surface 1221 poor. If light is irradiated to the first surface 1221, the diffraction phenomenon of the second pixel area 12c is further enhanced, thereby further deteriorating the display effect of the display panel. For example, the orthographic projections of each sub-conductive trace 121 on the substrate are arranged at intervals. Therefore, the present application can alleviate the influence of the first surface 1221 on the flatness of subsequent film layers through the planarization layer 140. Among them, in Fig.19 In the figure, since the auxiliary anode 150 covers the conductive trace 120, the conductive trace 120 is displayed as a dotted line to indicate that the conductive trace 120 is a perspective effect.

[0113] Exemplarily, an auxiliary anode 150 may be provided on the side of the planarization layer 140 facing away from the substrate, and the surface of the auxiliary anode 150 facing away from the substrate is relatively flat by providing the planarization layer 140. The material of the auxiliary anode 150 is a non-light-transmitting material, so that the light cannot be irradiated to the first surface 1221, but irradiates to the relatively flat auxiliary anode 150, which can alleviate the diffraction phenomenon caused by the gap of the conductive trace 120, thereby alleviating the haze of the display panel, and can also alleviate the reflectivity difference caused by the unevenness of the conductive trace 120, thereby alleviating the color unevenness phenomenon, and better improving the display effect.

[0114] In some embodiments, see Figure 1 and Fig.17 The display panel may include an auxiliary pixel 130, and the orthographic projection of the auxiliary pixel 130 on the substrate overlaps with the orthographic projection of the second pixel area 12c on the substrate. For example, the auxiliary pixel 130 may be located in the second pixel area 12c, and the auxiliary pixel 130 may be located on the side of the conductive trace 120 away from the substrate. For example, the auxiliary pixel 130 may be located on the side of the auxiliary anode 150 away from the substrate. With such a configuration, when the display panel is in a display state, the auxiliary pixel 130 may emit light to display a picture. For example, the user may adjust the brightness of the auxiliary pixel 130 according to the intensity of the ambient light, and the display function may be realized when the intensity of the external light is strong, so that the external object will not be reflected and imaged, thereby reducing the reflectivity of at least part of the second pixel area 12c, increasing the ambient light contrast of the display panel, and thus enhancing the readability of the display panel. In addition, the brightness of the display panel may be improved, the aperture ratio may be increased, and thus the display effect of the display panel and the display device may be improved, and the life of the display panel and the display device may be increased.

[0115] For example, the light emitting color of the auxiliary pixel 130 may include red, blue, green, white or other colors.

[0116] Exemplarily, the light-emitting colors of any two auxiliary pixels 130 may be the same, or may be different.

[0117] When the light emitted by the auxiliary pixel 130 is white, the auxiliary pixel 130 can be disposed at the edge of the display area 10 a , thereby alleviating the color edge phenomenon of the display panel in the display area 10 a , and better improving the display effect of the display panel and the display device.

[0118] In some embodiments, there may be a plurality of auxiliary pixels 130 between two adjacent first pixel regions 11 c . For example, there may be two, three, four or more auxiliary pixels 130 between two adjacent first pixel regions 11 c .

[0119] The auxiliary layer 160 provided in the embodiment of the present application is described below.

[0120] In some embodiments, see Figure 1 and Figure 2 The display panel may include multiple auxiliary layers 160, which may be stacked along the thickness direction of the substrate, and each of the multiple auxiliary layers 160 may be located between the pixel group 110 and the substrate, and each of the auxiliary layers 160 may cover the pixel area 10c. For example, any auxiliary layer 160 may be an insulating layer that isolates two adjacent sub-conductive traces 121, or other film layers.

[0121] For example, see Figure 1 and Figure 2 , two adjacent auxiliary layers 160 may include a first auxiliary layer 161 and a second auxiliary layer 162, the first auxiliary layer 161 may be located on a side of the second auxiliary layer 162 close to the substrate, the first auxiliary layer 161 may have a first orthographic projection on the substrate, the second auxiliary layer 162 may have a second orthographic projection on the substrate, the first orthographic projection may cover the second orthographic projection, and there is a gap between the outer edge of the first orthographic projection and the outer edge of the second orthographic projection, so that the first auxiliary layer 161 can better support the second auxiliary layer 162, and can also reduce the influence of the second auxiliary layer 162 on the transmittance of the light-transmitting area 10b.

[0122] For example, see Figure 1 and Figure 2 , the side wall of the auxiliary layer 160 may include a first side wall 1631 close to the first pixel area 11c, and the first side wall 1631 may be protruded in a direction away from the first pixel area 11c. The shape of the orthographic projection of the first side wall 1631 on the substrate may be an arc, or the shape of the orthographic projection of the first side wall 1631 on the substrate may be a polyline, and the angle between two adjacent sides of the polyline may be greater than 90°, so that the transition of the first side wall 1631 is smoother and more rounded, thereby alleviating the diffraction phenomenon caused by the step, so as to alleviate the haze of the display panel and improve the display effect of the display panel. In addition, it is also beneficial to expand the area of ​​the light-transmitting area 10b and improve the perspective effect of the display panel in the light-transmitting area 10b. Among them, the auxiliary layer 160 may have a plurality of through holes, and one through hole may be located in a corresponding light-transmitting area 10b. Since the auxiliary layer 160 is not provided at the through hole, the influence of the auxiliary layer 160 on the transmittance of the light-transmitting area 10b can be alleviated. The first side wall 1631 is also the hole wall of the through hole.

[0123] For example, the shape of the orthographic projection of the first side wall 1631 on the substrate may be a polyline, and the angle between two adjacent sides of the polyline may be 95°, 100°, 105°, 110°, or any value greater than 90°.

[0124] For example, see Figure 1 and Figure 2The sidewall of the auxiliary layer 160 may include a second sidewall 1632 close to the second pixel region 12c, and the shape of the positive projection of the second sidewall 1632 on the substrate is a straight line, thereby simplifying the preparation process of the second sidewall 1632 and reducing the preparation cost of the display panel.

[0125] In the case of using “including”, “having”, and “comprising” described herein, another component may be added unless a clear limiting term such as “only”, “consisting of”, etc. is used. Unless mentioned otherwise, a term in the singular form may include a plural form and should not be understood as being one in number.

[0126] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0127] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
