Description

Technical Field

[0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background Art

[0002] As an important component of a display device, a display panel is used to realize the display function of the display device. With the development of technology, a display panel with a simple rectangular display area can no longer meet the needs of consumers, and display panels with display areas of various shapes have emerged, such as circular or other shapes of smart wearable electronic products. Usually, the pixels in the display area are arranged in rows and columns, and the row direction and column direction are perpendicular to each other, so that when the display area has at least one virtual arc edge, the pixels set close to the virtual arc edge will be arranged in a jagged shape. Due to the presence of the jagged edges, when the display panel displays the picture, the edge of the display picture has jagged display defects.

[0003] Therefore, there is an urgent need to provide a display panel and a display device that can improve the jagged display defects at the edges of the displayed images. Summary of the invention

[0004] In view of this, the present invention provides a display panel and a display device to improve the problem of jagged display defects at the edges of a display image.

[0005] In one aspect, the present invention provides a display panel, comprising a display area and a non-display area at least partially surrounding the display area; the display area comprises at least one virtual irregular edge; the extension direction of the virtual irregular edge intersects both the first direction and the second direction, the first direction is a row direction, and the second direction is a column direction; the display panel comprises a substrate and a light-emitting layer located on one side of the substrate, the light-emitting layer comprises a plurality of light-emitting units arranged along the first direction and the second direction, the light-emitting units comprising micro light-emitting devices; the plurality of light-emitting units are arranged as a light-emitting unit row along the first direction, and the plurality of light-emitting units are arranged as a light-emitting unit column along the second direction;

[0006] The light-emitting units include a plurality of first light-emitting units overlapping with the virtual special-shaped edges in a direction perpendicular to the plane of the substrate and a plurality of remaining second light-emitting units; in the same row of light-emitting units and / or the same column of light-emitting units, the brightness of the first light-emitting units is less than the brightness of the second light-emitting units.

[0007] On the other hand, the present invention further provides a display device, comprising the above display panel.

[0008] Compared with the prior art, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0009] The display panel of the present invention has a display area, and the display area includes at least one virtual shaped edge; the light-emitting layer of the display panel includes a plurality of light-emitting units arranged along a first direction and a second direction, and the light-emitting units include micro-light-emitting devices; the light-emitting units include a plurality of first light-emitting units overlapping with the virtual shaped edge in a direction perpendicular to the plane where the substrate is located and a plurality of remaining second light-emitting units; in the same light-emitting unit row and / or the same light-emitting unit column, the brightness of the first light-emitting unit is less than the brightness of the second light-emitting unit. The light-emitting units arranged near the virtual shaped edge of the layout design are arranged in a zigzag shape, and the first light-emitting unit overlaps with the virtual shaped edge required by the customer, and the second light-emitting unit is a conventional light-emitting unit far away from the virtual shaped edge. When displaying, in the same light-emitting unit row and / or the same light-emitting unit column, the brightness of the first light-emitting unit is less than the brightness of the second light-emitting unit, so that the brightness of the first light-emitting unit near the virtual shaped edge is reduced, that is, the brightness of the virtual shaped edge area is reduced, so that the boundary of the display area is blurred, and the boundary line of the display area is closer to the virtual shaped edge in the user's visual sense, and is no longer an obvious zigzag edge of the first light-emitting unit, thereby weakening the sawtooth effect.

[0010] Of course, any product implementing the present invention does not necessarily need to achieve all of the technical effects described above at the same time.

[0011] Further features and advantages of the present invention will become apparent from the following detailed description of exemplary embodiments of the present invention with reference to the attached drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0027] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0028] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0029] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0030] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0031] In the prior art, there is a problem of jagged display at the edge of the display screen. The inventor has conducted the following research on the prior art: Figure 1 and Figure 2 , Figure 1 It is a schematic diagram of the planar structure of a display panel in the prior art; Figure 2 yes Figure 1 A partial enlarged view of the middle P region; Figure 1 The display panel 000 includes a display area AA' and a non-display area BB' at least partially surrounding the display area AA'; the display area AA' includes at least one virtual profiled edge K', where the virtual profiled edge K' is the boundary line of the display area AA' in the user's visual sense as required by the customer, and the extension direction of the virtual profiled edge K intersects both the first direction X and the second direction Y, the first direction X is the row direction, and the second direction Y is the column direction, the display panel 000 includes a plurality of light emitting units 3' arranged along the first direction X and the second direction Y, the plurality of light emitting units 3' are arranged as a light emitting unit row 5' along the first direction X, and the plurality of light emitting units 3 are arranged as a light emitting unit column 6 along the second direction Y, The first light-emitting unit 10' arranged near the virtual irregular edge K' in the layout design will be arranged in a zigzag shape, and the first light-emitting unit 10' will overlap with the virtual irregular edge K' required by the customer. The second light-emitting unit 11' is a regular light-emitting unit far away from the virtual irregular edge K'. When displaying, the brightness of the first light-emitting unit 10' and the brightness of the second light-emitting unit 11' are equal. Therefore, when the first light-emitting unit 10' and the second light-emitting unit 11' emit light, it can be clearly seen that the boundary of the display area is the zigzag arrangement boundary of the first light-emitting unit 10', rather than the virtual irregular boundary K' of the user's visual display area AA' required by the customer, and the visual zigzag is particularly obvious. Due to the existence of the zigzag, when the display panel displays the picture, the edge of the display picture has a zigzag display defect.

[0032] In view of this, the present invention provides a display panel and a display device for improving the problem of jagged display defects at the edges of a display image. Specific embodiments of the display panel and the display device will be described in detail below.

[0033] Reference Figure 3 , Figure 4 and Figure 5 , Figure 3 is a schematic diagram of a planar structure of a display panel provided by the present invention, Figure 4 yes Figure 3 A partial enlarged view of the middle M area. Figure 5 yes Figure 4 A cross-sectional view along the A-A' direction.

[0034] Combination Figure 3 , Figure 4 and Figure 5The display panel 100 in this embodiment includes a display area AA and a non-display area BB at least partially surrounding the display area AA; the display area AA includes at least one virtual irregular edge K; the extension direction of the virtual irregular edge K intersects with both the first direction X and the second direction Y, the first direction X is the row direction, and the second direction Y is the column direction; the display panel 100 includes a base substrate 1 and a light-emitting layer 2 located on one side of the base substrate 1, the light-emitting layer 2 includes a plurality of light-emitting units 3 arranged along the first direction X and the second direction Y, the light-emitting unit 3 includes a micro light-emitting device 4; the plurality of light-emitting units 3 are arranged as a light-emitting unit row 5 along the first direction X, and the plurality of light-emitting units 3 are arranged as a light-emitting unit column 6 along the second direction Y;

[0035] The light-emitting unit 3 includes a plurality of first light-emitting units 10 and a plurality of remaining second light-emitting units 11 that overlap with the virtual special-shaped edge K in a direction perpendicular to the plane of the substrate 1; in the same light-emitting unit row 5 and / or the same light-emitting unit column 6, the brightness of the first light-emitting unit 10 is less than the brightness of the second light-emitting unit 11.

[0036] Specifically, Figure 3 1 shows that the display panel 100 includes a display area AA and a non-display area BB surrounding the display area AA. The display area AA includes four virtual shaped edges K. Of course, the shapes and numbers of the virtual shaped edges K are schematically illustrated. The extension direction of the virtual shaped edges K intersects both the row direction and the column direction. Figure 3 The virtual irregular edge K in the embodiment is only a convex arc edge at the R angle position, and can also be a circular edge corresponding to the camera set in the display area AA, which is not specifically limited here. It should be noted that the virtual irregular edge K in the present invention is a theoretical edge of the display area AA required by the customer, and is a theoretical visual edge. However, since the light-emitting unit 3 cannot be completely manufactured according to the virtual irregular edge K during design and manufacturing, part of the light-emitting unit 3 will overlap with the theoretical visual edge, such as Figure 4 As shown in the figure, in the first row of light-emitting units 5, two light-emitting units 3 overlap with the virtual irregular edge K. Of course, there is no limitation on the number of first light-emitting units 5 overlapping with the virtual irregular edge K, which is determined according to the design of the actual product.

[0037] Optional, see Figure 5The display panel includes a base substrate 1 and a light-emitting layer 2 located on one side of the base substrate 1, and the light-emitting unit 3 includes a micro-light-emitting device 4; the light-emitting layer 2 also includes a shading layer 7 on the side away from the base substrate 1, and the shading layer 7 includes a light-transmitting area 8 and a shading structure 9 surrounding the light-transmitting area 8. In a direction perpendicular to the plane where the base substrate 1 is located, the light-transmitting area 8 overlaps with the light-emitting unit 3; the shading structure 9 in this embodiment can be a black matrix. When the display panel is observed from the light-emitting surface of the display panel 100 in the present invention, the position corresponding to the light-transmitting area 8 is the opening area of ​​the pixel of the display panel.

[0038] Optionally, the light-emitting unit 3 schematically shows that it includes three sub-light-emitting units 12, each of which is provided with a micro-light-emitting device 4, and each micro-light-emitting device 4 can emit red light, green light and blue light, which is not specifically limited here. Figure 5 The light-emitting layer 2 further includes a retaining wall 13 , and the micro light-emitting device 4 is arranged in a groove of the retaining wall 13 .

[0039] It can be understood that the micro-light emitting device 4 (i.e., Micro LED) has the following beneficial effects: First, Micro LED is a micron-level pitch LED array formed by miniaturizing traditional LED to achieve ultra-high density pixel resolution, that is, the Micro LED array is a high-density integrated micron-level pitch LED array, each LED in the array can be used as a pixel point, independently addressed and lit, that is, each LED pixel in the Micro LED array can emit light by itself, and through the precise control of the luminous intensity of each LED, the image display can be realized, that is, the Micro LED array can directly emit image light. Secondly, in addition to achieving high brightness, ultra-high resolution and color saturation, and high luminous efficiency, Micro LED is more importantly not affected by water vapor, oxygen or high temperature, so Micro LED has obvious advantages in stability, service life, operating temperature, etc. In addition, the power consumption of Micro LED is about 10% of LCD and 50% of OLED; compared with OLED, only about 10% of the coating area of ​​the latter is required to achieve the same display brightness.

[0040] Figure 5 It is also shown that there is an array layer 14 between the base substrate 1 and the light-emitting layer 2. The array layer 14 includes a driving circuit (not shown in the figure) for driving the micro light-emitting device 4 to emit light. Of course, the structure of the micro light-emitting device 4 here is only for schematic illustration.

[0041] When the light-emitting unit 3 of the present invention is provided with the display panel 100 in the entire display area AA and the non-display area BB for display, the light observed is the light emitted by the micro-light-emitting device 4 and passing through the light-transmitting area 8 and the light-emitting surface of the display panel.

[0042] like Figure 4 In the display area AA, the light-emitting unit 3 includes a plurality of first light-emitting units 10 and a plurality of remaining second light-emitting units 11 overlapping with the virtual special-shaped edge K in a direction perpendicular to the plane of the substrate 1; it can be understood that, when the light-emitting unit 3 has a plurality of sub-light-emitting units 12, the area of ​​the light-transmitting area 8 overlapping with the light-emitting unit 3 refers to the sum of the total areas of the light-transmitting areas 8 overlapping with each sub-light-emitting unit 12.

[0043] like Figure 4 The first row of light-emitting units 5 in the diagram includes two first light-emitting units 10 and a second light-emitting unit 11, wherein the two first light-emitting units 10 are respectively a first light-emitting unit 10a and a first light-emitting unit 10b, wherein the brightness of the first light-emitting unit 10a and the first light-emitting unit 10b is lower than the brightness of the second light-emitting unit 11. Of course, the brightness of the first light-emitting unit 10a and the brightness of the first light-emitting unit 10b may be equal or different, and no specific limitation is made here.

[0044] In the prior art, the brightness of the first light-emitting unit 10 and the second light-emitting unit 11 are the same, so when the display panel is displaying, the light-transmitting area where the display area overlaps with the first light-emitting unit will emit light with the same brightness. When the first light-emitting unit 10 and the second light-emitting unit 11 emit light, it can be clearly seen that the boundary of the display area is the zigzag arrangement boundary of the first light-emitting unit 10, rather than the virtual irregular boundary K of the display area AA required by the customer. The visual zigzag is particularly obvious. Due to the presence of zigzags, when the display panel displays a picture, the edge of the display picture has a zigzag display defect.

[0045] In this embodiment, in the same light-emitting unit row 5 and / or the same light-emitting unit column 6, the brightness of the first light-emitting unit is less than the brightness of the second light-emitting unit, so that the brightness of the first light-emitting unit close to the virtual special-shaped edge is reduced, that is, the brightness of the virtual special-shaped edge area is reduced, thereby blurring the boundary of the display area. Visually, the boundary line of the display area is closer to the virtual special-shaped edge to the user, and is no longer the obvious edge of the zigzag arrangement of the first light-emitting unit, thereby weakening the zigzag effect.

[0046] In some optional embodiments, continue to refer to Figure 3-Figure 5 The display panel 100 includes a light-emitting unit group 40, which includes at least three light-emitting units 3 arranged continuously in the same light-emitting unit row 5 or the same light-emitting unit column 6; the at least three light-emitting units 3 include a second light-emitting unit 11 and at least two first light-emitting units 10; in the light-emitting unit group 40, the brightness of the first light-emitting unit 10 that is closer to the second light-emitting unit 11 is greater than or equal to the brightness of the first light-emitting unit 10 that is farther away from the second light-emitting unit 11.

[0047] Figure 4 It is only shown that the light emitting unit group 40 includes at least three light emitting units 3 arranged continuously in the same light emitting unit row 5. Of course, the light emitting unit group 40 may also include at least three light emitting units 3 arranged continuously in the same light emitting unit column 6, which is not specifically limited here.

[0048] In the prior art, regardless of whether the first light-emitting unit is closer to the second light-emitting unit or the first light-emitting unit is farther from the second light-emitting unit, the brightness is the same. Therefore, when the display panel is displaying, the brightness of the first light-emitting unit and the second light-emitting unit overlapping with the virtual irregular edge is the same. It can be very clearly seen that the boundary of the display area is the zigzag boundary of the first light-emitting unit 10, rather than the virtual irregular boundary K of the display area AA required by the customer. The visual jaggies are particularly obvious, and there are jagged display defects on the edges of the displayed screen.

[0049] Reference Figure 4 , the light emitting unit group 40 includes at least three light emitting units 3 arranged continuously in the same light emitting unit row 5 or the same light emitting unit column 6; the at least three light emitting units 3 include one second light emitting unit 11 and at least two first light emitting units 10; in the light emitting unit group 40, the brightness of the first light emitting unit 10 that is closer to the second light emitting unit 11 is greater than or equal to the brightness of the first light emitting unit 10 that is farther from the second light emitting unit 11. In the first light emitting unit row 5, the first light emitting unit 10a is farther from the second light emitting unit 11, and the first light emitting unit 10b is closer to the second light emitting unit 11, so the brightness of the first light emitting unit 10b is greater than or equal to the brightness of the first light emitting unit 10a.

[0050] In this embodiment, the brightness of the first light-emitting unit 10 that is closer to the second light-emitting unit 11 is greater than or equal to the brightness of the first light-emitting unit 10 that is farther from the second light-emitting unit 11. In this way, the brightness of the first light-emitting unit close to the virtual special-shaped edge is reduced, that is, the brightness of the virtual special-shaped edge area is reduced, so that the boundary of the display area is blurred, and the boundary line of the display area is closer to the virtual special-shaped edge to the user's vision, and is no longer an obvious zigzag edge of the first light-emitting unit, thereby weakening the sawtooth effect; in addition, the brightness of the first light-emitting unit 10 that is closer to the second light-emitting unit 11 is greater than or equal to the brightness of the first light-emitting unit 10 that is farther from the second light-emitting unit 11, which can make the brightness of the first light-emitting unit 10 close to the virtual special-shaped edge smaller and the brightness close to the second light-emitting unit 11 larger, so that the brightness gradually transitions to the brightness of the second light-emitting unit 11, which will further weaken the sawtooth, and the boundary line of the display area is closer to the virtual special-shaped edge to the user's vision, and the display effect is better.

[0051] Of course, it is understandable that if there is only one first light emitting unit 10 and one second light emitting unit 11 in a light emitting unit group 40, such as Figure 4 In the third row of light-emitting units, the brightness of the first light-emitting unit 10 is lower than that of the second light-emitting unit 11 in the direction from the non-display area BB to the display area AA. In this way, on the side of the virtual irregular edge K close to the display area AA, the brightness does not suddenly increase to the brightness of the second light-emitting unit 11, but gradually transitions to the brightness of the second light-emitting unit 11, which can further improve the sawtooth effect at the virtual irregular edge K.

[0052] In some optional embodiments, continue to refer to Figure 4 and Figure 5 , in the direction from the non-display area BB to the display area AA, the brightness of the first light emitting unit 10 in the light emitting unit group 40 gradually increases.

[0053] Reference Figure 4 , the light emitting unit group 40 includes at least three light emitting units 3 arranged continuously in the same light emitting unit row 5 or the same light emitting unit column 6; the at least three light emitting units 3 include a second light emitting unit 11 and at least two first light emitting units 10; Figure 4 The first row of light-emitting units 5 in the embodiment includes three first light-emitting units 10 and second light-emitting units 11, and the three first light-emitting units 10 are respectively the first light-emitting unit 10a and the first light-emitting unit 10b. In the light-emitting unit group 40, in the direction from the non-display area BB to the display area AA, the brightness of the first light-emitting units 10 in the light-emitting unit group 40 gradually increases. In the first row of light-emitting units 5, the distance between the first light-emitting unit 10a, the first light-emitting unit 10b and the second light-emitting unit 11 gradually decreases, that is, the closer the first light-emitting unit 10b is to the second light-emitting unit 11, the brightness of the first light-emitting unit 10a, the first light-emitting unit 10b gradually increases. In this way, the brightness of the first light-emitting unit close to the virtual special-shaped edge is reduced, that is, the brightness of the virtual special-shaped edge area is reduced, so that the boundary of the display area is blurred, and the boundary line of the display area is closer to the virtual special-shaped edge to the user's vision, and is no longer an obvious zigzag edge of the first light-emitting unit, thereby weakening the sawtooth effect; in addition, in the direction from the non-display area BB to the display area AA, the brightness of the first light-emitting unit 10 in the light-emitting unit group 40 gradually increases, and the brightness of the first light-emitting unit close to the virtual special-shaped edge K will not suddenly increase to the brightness of the second light-emitting unit 11. From the direction away from the second light-emitting unit 11 to the direction close to the second light-emitting unit 11, the brightness of the first light-emitting unit 10 in the light-emitting unit group 40 gradually increases, forming a gradient transition with the brightness of the second light-emitting unit 11, thereby further weakening the sawtooth effect, and the boundary line of the display area is closer to the virtual special-shaped edge to the user's vision, and the display effect is better.

[0054] In some optional embodiments, continue to refer to Figure 4 and Figure 5 In the same light-emitting unit row and / or the same light-emitting unit column, the current provided to the first light-emitting unit 10 is smaller than the current provided to the second light-emitting unit.

[0055] It is understandable that the light-emitting unit 3 in the present invention is provided with a micro-light-emitting device 4, and each micro-light-emitting device 4 can emit light independently, and different currents can be provided to the micro-light-emitting devices 4 to accurately control the brightness.

[0056] Of course, the greater the current provided to the light-emitting unit 3, the greater the brightness, and the smaller the current provided to the light-emitting unit 3, the smaller the brightness. In the same light-emitting unit row 5 and / or the same light-emitting unit column 6 in this embodiment, the current provided to the first light-emitting unit 10 is less than the current provided to the second light-emitting unit 11, which can ensure that the brightness of the first light-emitting unit 10 is less than the brightness of the second light-emitting unit 11. The brightness of the first light-emitting unit 10 near the virtual profile edge will not suddenly increase to the brightness of the second light-emitting unit 11. In the direction from the non-display area to the display area, the brightness gradually reaches the brightness of the second light-emitting unit 11, thereby blurring the boundary of the display area and not showing obvious jagged edges, thereby weakening the jagged effect.

[0057] In some optional embodiments, continue to refer to Figure 4 and Figure 5 , the current provided to the first light-emitting unit 10 which is closer to the second light-emitting unit 11 is greater than or equal to the current provided to the first light-emitting unit 10 which is farther from the second light-emitting unit 11 .

[0058] It is understandable that the light-emitting unit 3 in the present invention is provided with a micro-light-emitting device 4, and each micro-light-emitting device 4 can emit light independently, and different currents can be provided to the micro-light-emitting devices 4 to accurately control the brightness. As described above, the greater the current provided to the light-emitting unit 3, the greater the brightness, and the smaller the current provided to the light-emitting unit 3, the smaller the brightness.

[0059] If the current provided to the first light-emitting unit 10 that is closer to the second light-emitting unit 11 is greater than or equal to the current provided to the first light-emitting unit 10 that is farther from the second light-emitting unit 11, then the brightness of the first light-emitting unit 10 that is closer to the second light-emitting unit 11 is greater than or equal to the brightness of the first light-emitting unit 10 that is farther from the second light-emitting unit 11. In this way, the brightness of the first light-emitting unit close to the virtual irregular edge is reduced, that is, the brightness of the virtual irregular edge area is reduced, thereby blurring the boundary of the display area. Visually, the boundary line of the display area is closer to the virtual irregular edge to the user, and is no longer an obvious zigzag edge of the first light-emitting unit, thereby weakening the sawtooth effect; in addition, the current provided to the first light-emitting unit 10 that is closer to the second light-emitting unit 11 is greater than or equal to the current provided to the first light-emitting unit 10 that is farther from the second light-emitting unit 11, and the brightness of the first light-emitting unit 10 close to the virtual irregular edge K will not suddenly increase to the brightness of the second light-emitting unit 11, and the brightness will gradually transition to the brightness of the second light-emitting unit 11, further weakening the sawtooth effect.

[0060] In some optional embodiments, in the direction from the non-display area BB to the display area AA, the current provided to the first light-emitting unit 10 in the light-emitting unit group 40 gradually increases, and the brightness gradually transitions to the brightness of the second light-emitting unit 11. The boundary of the display area will be further blurred, and visually the boundary line of the display area will be closer to the virtual special-shaped edge, further weakening the sawtooth effect.

[0061] In some optional embodiments, continue to refer to Figure 4 and Figure 5 , the current provided to the second light emitting unit 11 is I, the current provided to the first light emitting unit 10 is I', I'=(S' / S) 2 . 2 ×I, wherein the virtual profiled edge K divides the first light-emitting unit 10 into a first portion 1001 and a second portion 1002, the first portion 1001 is the portion of the first light-emitting unit 10 close to the second light-emitting unit 11, S' is the light-transmitting area of ​​the first portion 1001, and S is the light-transmitting area of ​​the second light-emitting unit.

[0062] The current provided to the first light-emitting unit 10 is smaller than the current provided to the second light-emitting unit 11, which can ensure that the brightness of the first light-emitting unit 10 is smaller than the brightness of the second light-emitting unit 11. Therefore, by adjusting the current provided to the first light-emitting unit 10 to I', the light output brightness of the first light-emitting unit 10 can be changed. In this embodiment, I'=(S' / S) 2 . 2×I, because the virtual profiled edge K overlaps with the first light-emitting unit 10, the first light-emitting unit 10 is divided into two parts by the virtual profiled edge K, one part is on the side of the first light-emitting unit 10 close to the non-display area BB, and the other part of the first light-emitting unit 10 is in the display area AA. Therefore, the current provided to the first light-emitting unit 10 can be determined based on the area size of the part of the first light-emitting unit 10 located in the display area AA (i.e., the first part 1001) as the main factor to achieve that the brightness of the first light-emitting unit 10 is less than that of the second light-emitting unit 11. It should be noted that when adjusting the brightness, the brightness is adjusted according to the gamma2.2 curve. Of course, under the premise that the resistance of the micro-light-emitting device remains unchanged, the greater the voltage provided, the greater the current, and the higher the brightness, and gamma2.2 is more in line with the human eye's perception of brightness. This embodiment determines the current size to the first light-emitting unit 10 based on the gamma2.2 curve, so that the brightness of the first light-emitting unit 10 is less than that of the second light-emitting unit. In this way, the brightness of the first light-emitting unit close to the virtual special-shaped edge is reduced, thereby blurring the boundary of the display area, and no obvious jagged edges are displayed, thereby improving the jagged effect.

[0063] In some optional embodiments, continue to refer to Figure 3 The non-display area BB includes a frame, and the junction of two adjacent frames includes a first outer edge 22, wherein the width of one frame in the first direction is a, and the width of the other frame in the second direction is b, and the distance between the virtual special-shaped edge K and the first edge is c, wherein b<c<a, or a<c<b.

[0064] In this embodiment, the virtual irregular edge K is at the R corner position, and the non-display area BB includes an upper frame 21a, a lower frame 21b, a left frame 21c, and a right frame 21d. The junction of the upper frame 21a and the left frame 21c has a first outer edge 22. Of course, the junction of the upper frame 21a and the right frame 21d, the junction of the lower frame 21b and the left frame 21c, and the junction of the lower frame 21b and the right frame 21d also have a first outer edge 22. Figure 3 Not marked in Figure 3 In the example, b<c<a is used for illustration. The width of the left frame 21c in the first direction X is a, the width of the upper frame 21 in the second direction Y is b, the distance between the virtual profile edge K and the first outer edge 22 is c, b<c<a, Figure 3In the example, b<c<a is used for illustration, and a<c<b may also be used, which is not specifically limited here. Thus, by setting the size of c between the sizes of a and b, the position of the virtual profiled edge K is set according to the user's requirements, and the boundary line of the display area in the user's visual sense is preset to achieve a better display effect. In addition, by adjusting the brightness of the first light-emitting unit around the virtual profiled edge K to be lower than the brightness of the second light-emitting unit, the sawtooth phenomenon in the virtual profiled edge area can be weakened.

[0065] In some optional embodiments, referring to Figure 6 and Figure 7 , Figure 6 is a schematic diagram of a planar structure of a display panel provided by the present invention, Figure 7 yes Figure 6 A partial enlarged view of the middle Q area. Figure 6 The circular edge of the camera is set in the middle display area AA, that is, Figure 6 The virtual shaped edge K in the embodiment is a circular edge, and the corresponding circular area is a non-display area for placing a camera. No light is emitted from the circular area. Of course, the position of the virtual shaped edge K in the present invention is not specifically limited. Figure 7 The virtual irregular edge K in the image overlaps with the first light emitting unit 10 . Figure 7 In the same light-emitting unit row 5 and / or the same light-emitting unit column 6, the brightness of the first light-emitting unit 10 can be less than the brightness of the second light-emitting unit 11. This can ensure that the brightness of the side of the virtual special-shaped edge K close to the display area AA will not suddenly increase to the brightness of the second light-emitting unit 11, and the brightness will gradually transition to the brightness of the second light-emitting unit 11. The boundary of the display area is further blurred, thereby further weakening the sawtooth effect.

[0066] In some optional embodiments, continue to refer to 4 and Figure 5 The orthographic projection areas of the micro-light emitting devices 4 of the plurality of first light emitting units 10 on the plane where the substrate 1 is located are all equal.

[0067] In this embodiment, the orthographic projection area of ​​the micro-light emitting device 4 of the first light emitting unit 10 on the plane where the base substrate 1 is located refers to the sum of the orthographic projection areas of the micro-light emitting devices 4 of each sub-light emitting unit on the plane where the base substrate 1 is located. Figure 4 The orthographic projection areas of the micro-light emitting devices 4 in the first light emitting unit 10a and the first light emitting unit 10b on the plane where the substrate 1 is located are equal.

[0068] In this embodiment, the current provided to the first light-emitting unit 10 which is closer to the second light-emitting unit 11 is greater than or equal to the current provided to the first light-emitting unit 10 which is farther away from the second light-emitting unit 11, but the orthographic projection areas of the micro-light-emitting devices 4 of the plurality of first light-emitting units 10 on the plane where the substrate 1 is located are all equal, that is, the light brightness is adjusted only by adjusting the current of the first light-emitting unit 10.

[0069] The orthographic projection areas of the micro-light emitting devices 4 of the plurality of first light emitting units 10 on the plane where the substrate 1 is located are all equal, which can facilitate mass production, is easy to implement, and reduces production costs.

[0070] In some optional embodiments, referring to Figure 8 and Fig. 9 , Figure 8 yes Figure 3 Another partial enlarged view of the middle M area, Fig. 9 yes Figure 8 In a cross-sectional view taken along line BB′, the orthographic projection area of ​​the micro-light emitting device 4 of the first light emitting unit 10 on the plane where the base substrate 1 is located is smaller than the orthographic projection area of ​​the micro-light emitting device 4 of the second light emitting unit 11 on the plane where the base substrate 1 is located.

[0071] Specifically, in this embodiment, the orthographic projection area of ​​the micro-light emitting device 4 of the first light emitting unit 10 on the plane where the base substrate 1 is located refers to the sum of the orthographic projection areas of the micro-light emitting devices 4 of each sub-light emitting unit on the plane where the base substrate 1 is located.

[0072] It is understandable that the smaller the orthographic projection area of ​​the micro-light-emitting device 4 on the plane where the substrate 1 is located, that is, the smaller the size of the micro-light-emitting device 4, the less fluorescent powder can be accommodated in the micro-light-emitting device 4 for luminescence, the lower the external quantum efficiency, and the lower the brightness.

[0073] The smaller the orthographic projection area of ​​the micro-light emitting device 4 of the first light emitting unit 10 on the plane where the substrate 1 is located, the smaller the brightness of the first light emitting unit 10. Figure 8 As shown, the orthographic projection area of ​​the micro-light emitting device 4 of the first light-emitting unit 10 on the plane where the substrate 1 is located is smaller than the orthographic projection area of ​​the micro-light emitting device 4 of the second light-emitting unit 11 on the plane where the substrate 1 is located, which can ensure that the brightness of the first light-emitting unit 10 is lower than the brightness of the second light-emitting unit 11, and the brightness will gradually transition to the brightness of the second light-emitting unit 11, thereby further blurring the boundary of the display area. Visually, the boundary line of the display area is closer to a virtual special-shaped edge rather than the obvious zigzag edge of the first light-emitting unit, thereby weakening the zigzag effect.

[0074] In some optional embodiments, continue to refer to Figure 8 and Fig. 9 , Figure 8 yes Figure 3 Another partial enlarged view of the middle M area, Fig. 9 yes Figure 8 A cross-sectional view along the B-B' direction. Figure 8 and Fig. 9 As shown, the orthographic projection area of ​​the micro-light emitting device 4 of the first light emitting unit 10 which is farther away from the second light emitting unit 11 on the plane where the substrate 1 is located is smaller than the orthographic projection area of ​​the micro-light emitting device 4 of the first light emitting unit 10 which is closer to the second light emitting unit 11 on the plane where the substrate 1 is located.

[0075] Specifically, in this embodiment, the orthographic projection area of ​​the micro-light emitting device 4 of the first light emitting unit 10 on the plane where the substrate 1 is located refers to the sum of the orthographic projection areas of the micro-light emitting devices 4 of each sub-light emitting unit on the plane where the substrate 1 is located. The smaller the orthographic projection area of ​​the micro-light emitting device 4 of the first light emitting unit 10 that is farther away from the second light emitting unit 11 on the plane where the substrate 1 is located, the smaller the area of ​​the light-transmitting area 8 that overlaps with the first light emitting unit 10 can be, such as Figure 8 As shown, the area of ​​the light-transmitting region 8 overlapping the first light-emitting unit 10 which is farther away from the second light-emitting unit 11 is smaller than the area of ​​the light-transmitting region 8 overlapping the first light-emitting unit 10 which is closer to the second light-emitting unit 11 .

[0076] It can be understood that the larger the orthographic projection area of ​​the micro-light-emitting device 4 on the plane where the substrate 1 is located, that is, the larger the size of the micro-light-emitting device 4, the more fluorescent powder for luminescence can be accommodated in the micro-light-emitting device 4, the higher the external quantum efficiency and the higher the brightness.

[0077] The orthographic projection area of ​​the micro-light emitting device 4 of the first light emitting unit 10a which is farther away from the second light emitting unit 11 on the plane where the substrate 1 is located is smaller than the orthographic projection area of ​​the micro-light emitting device 4 of the first light emitting unit 10b which is closer to the second light emitting unit 11 on the plane where the substrate 1 is located, so that the brightness of the first light emitting unit 10a which is farther away from the second light emitting unit 11 is smaller than the brightness of the first light emitting unit 10b which is closer to the second light emitting unit 11, and the brightness of the side of the virtual special-shaped edge K close to the display area AA will not suddenly increase to the brightness of the second light emitting unit 11, and the brightness will gradually transition to the brightness of the second light emitting unit 11, thereby weakening the sawtooth effect.

[0078] In some optional embodiments, continue to refer to Figure 4 The light-emitting unit includes multiple sub-light-emitting units 12. In the same first light-emitting unit 10, the brightness of the sub-light-emitting unit 12 that is closer to the second light-emitting unit 11 is greater than or equal to the brightness of the sub-light-emitting unit 12 that is farther away from the second light-emitting unit 11.

[0079] It can be understood that each light-emitting unit 3 may include a self-luminous unit 3 that emits red light, green light and blue light. In the direction perpendicular to the plane where the light-emitting surface of the display panel is located, the first light-emitting unit 10 overlaps with the virtual special-shaped edge K, then at least one sub-light-emitting unit 12 in the same first light-emitting unit 10 overlaps with the virtual special-shaped edge K, and the brightness of the sub-light-emitting unit 12 that is closer to the second light-emitting unit 11 is greater than or equal to the brightness of the sub-light-emitting unit 12 that is farther away from the second light-emitting unit 11. The brightness of the first light-emitting unit 11 close to the virtual special-shaped edge K will not suddenly increase to the brightness of the second light-emitting unit 11. In the direction from the non-display area BB to the display area AA, the brightness of the sub-light-emitting unit 12 in each first light-emitting unit 10 will gradually transition to the brightness of the sub-light-emitting unit 12 in the second light-emitting unit 11, which can further weaken the jagged effect.

[0080] Of course, optionally, in the direction from the non-display area BB to the display area AA, the brightness of each light-emitting unit 3 in the same first light-emitting unit 10 gradually increases, and the brightness of the sub-light-emitting unit 12 in each first light-emitting unit 10 gradually transitions to the brightness of the sub-light-emitting unit 12 in the second light-emitting unit 11, thereby further blurring the boundary of the display area, and the edge is not an obvious zigzag arrangement, which can further weaken the zigzag effect.

[0081] Optionally, continue to refer to Figure 4 , in the same first light-emitting unit 10, the current provided to the sub-light-emitting unit 12 closer to the second light-emitting unit 11 is greater than or equal to the current provided to the sub-light-emitting unit 12 farther from the second light-emitting unit 11. It can be understood that in the present invention, each sub-light-emitting unit 12 is provided with a micro-light-emitting device 4, and each micro-light-emitting device 4 can emit light independently, and the brightness can be accurately controlled by providing different currents to the micro-light-emitting devices 4. In the same first light-emitting unit 10, the current provided to the sub-light-emitting unit 12 closer to the second light-emitting unit 11 is greater than or equal to the current provided to the sub-light-emitting unit 12 farther from the second light-emitting unit 11, then the brightness of the sub-light-emitting unit 12 closer to the second light-emitting unit 11 is greater than or equal to the brightness of the sub-light-emitting unit 12 farther from the second light-emitting unit 11, so that in the direction from the non-display area BB to the display area AA, the brightness of the sub-light-emitting unit 12 in each first light-emitting unit 10 will gradually transition to the brightness of the sub-light-emitting unit 12 in the second light-emitting unit 11, which can further weaken the sawtooth effect. Of course, if the current provided to each sub-light emitting unit 12 in the second light emitting unit 11 is I, the current provided to each sub-light emitting unit 12 in the first light emitting unit 10 is I1′=(S1′ / S1) 2 . 2×I1, the virtual special-shaped edge K overlaps with the sub-light-emitting unit 12, so the light-emitting unit 12 is divided into two parts by the virtual special-shaped edge K, one part is on the side of the sub-light-emitting unit 12 close to the non-display area BB, and one part of the sub-light-emitting unit 12 is in the display area AA, S1' is the light-transmitting area area of ​​the sub-light-emitting unit 12 in the display area AA, and S1 is the light-transmitting area 8 area overlapping with each sub-light-emitting unit 12 of the second light-emitting unit 11. In this way, in the direction from the non-display area BB to the display area AA, the brightness of the sub-light-emitting unit 12 in each first light-emitting unit 10 will gradually transition to the brightness of the sub-light-emitting unit 12 in the second light-emitting unit 11, thereby further blurring the boundary of the display area, which is not an obvious zigzag edge, and can further weaken the zigzag effect.

[0082] Optionally, refer to Fig.10 , Fig.10 yes Figure 3 Another partial enlarged view of the middle M area, in the same first light-emitting unit 10, the area of ​​the light-transmitting area 8 corresponding to the sub-light-emitting unit 12 farther from the second light-emitting unit 11 is smaller than the area of ​​the light-transmitting area 8 corresponding to the sub-light-emitting unit 12 closer to the second light-emitting unit 11. Of course, the area of ​​the light-transmitting area 8 corresponding to the sub-light-emitting unit 12 farther from the second light-emitting unit 11 is smaller than the area of ​​the light-transmitting area 8 corresponding to the sub-light-emitting unit 12 closer to the second light-emitting unit 11. At this time, the area overlapping with the light-transmitting area 8 in the first light-emitting unit 10 can be adjusted, and the amount of light emitted through the light-transmitting area 8 can be adjusted to change the brightness. In the direction from the non-display area BB to the display area AA, the brightness of each light-emitting unit 3 in the same first light-emitting unit 10 gradually increases, and the brightness of the sub-light-emitting unit 12 in each first light-emitting unit 10 will gradually transition to the brightness of the sub-light-emitting unit 12 in the second light-emitting unit 11, thereby further blurring the boundary of the display area, which is not an obvious zigzag edge, and can further weaken the zigzag effect.

[0083] Optionally, refer to Fig.11 , Fig.11 yes Fig.10 A cross-section taken along the C-C' direction. Fig.11Each sub-light-emitting unit 12 is provided with a micro-light-emitting device 4. In the same first light-emitting unit 10, the orthographic projection area of ​​the micro-light-emitting device 4 of the sub-light-emitting unit 12 which is farther away from the second light-emitting unit 11 on the plane where the substrate 1 is located is smaller than the orthographic projection area of ​​the micro-light-emitting device 4 of the sub-light-emitting unit 12 which is closer to the second light-emitting unit 11 on the plane where the substrate 1 is located. In the present invention, each sub-light-emitting unit 12 is provided with a micro-light-emitting device 4, and each micro-light-emitting device 4 can emit light independently. The larger the orthographic projection area of ​​the micro-light-emitting device 4 on the plane where the substrate 1 is located, that is, the larger the size of the micro-light-emitting device 4, the more fluorescent powder for luminescence can be accommodated in the micro-light-emitting device 4, the higher the external quantum efficiency, and the higher the brightness. In the same first light-emitting unit 10, the orthographic projection area of ​​the micro-light-emitting device 4 of the sub-light-emitting unit 12 which is farther away from the second light-emitting unit 11 on the plane where the substrate 1 is located is smaller than the orthographic projection area of ​​the micro-light-emitting device 4 of the sub-light-emitting unit 12 which is closer to the second light-emitting unit 11 on the plane where the substrate 1 is located, so that the brightness of the sub-light-emitting unit 12 which is farther away from the second light-emitting unit 11 is smaller than the brightness of the sub-light-emitting unit 12 which is closer to the second light-emitting unit 11, and the brightness of the side of the virtual special-shaped edge K close to the display area AA will not suddenly increase to the brightness of the second light-emitting unit 11, and the brightness will gradually transition to the brightness of the second light-emitting unit 11, thereby further blurring the boundary of the display area, which is not an obvious zigzag edge, thereby weakening the zigzag effect.

[0084] In some optional embodiments, continue to refer to Figure 4 and Figure 5 Each sub-light emitting unit 12 is provided with a micro-light emitting device 4. In the same first light emitting unit 10, the orthographic projection areas of the micro-light emitting devices 4 of the sub-light emitting units 12 on the plane where the substrate 1 is located are equal.

[0085] At least one sub-light-emitting unit 12 in the same first light-emitting unit 10 overlaps with the virtual special-shaped edge K, and the brightness of the sub-light-emitting unit 12 closer to the second light-emitting unit 11 is greater than or equal to the brightness of the sub-light-emitting unit 12 farther from the second light-emitting unit 11. In the direction from the non-display area BB to the display area AA, the brightness of the sub-light-emitting unit 12 in each first light-emitting unit 10 will gradually transition to the brightness of the sub-light-emitting unit 12 in the second light-emitting unit 11. Of course, at this time, in order to ensure that the brightness of the sub-light-emitting unit 12 in each first light-emitting unit 10 will gradually transition to the brightness of the sub-light-emitting unit 12 in the second light-emitting unit 11, the current provided to the sub-light-emitting unit 12 closer to the second light-emitting unit 11 in the same first light-emitting unit 10 is greater than or equal to the current provided to the first light-emitting unit 10 farther from the second light-emitting unit 11, which can further weaken the sawtooth effect. In the same first light-emitting unit 10, the orthographic projection areas of the micro-light-emitting devices 4 of the sub-light-emitting units 12 on the plane where the substrate 1 is located are equal, which is convenient for manufacturing and easy to implement.

[0086] In some optional embodiments, continue to refer to Figure 5 , Fig. 9 and Fig.11 The light-emitting unit 3 includes a plurality of sub-light-emitting units 12, and the light-emitting layer 2 further includes a retaining wall 13. The retaining wall 13 includes a plurality of grooves, which define the boundaries of the sub-light-emitting units 12, and the micro-light-emitting devices 4 are arranged in the grooves.

[0087] Specifically, in this embodiment, the display panel includes a light-emitting layer 2 located on one side of the base substrate 1. Optionally, the light-emitting layer 2 further includes a light-shielding layer 7 on a side away from the base substrate 1. The light-shielding layer 7 includes a light-transmitting area 8 and a light-shielding structure 9 surrounding the light-transmitting area 8. In a direction perpendicular to the plane where the base substrate 1 is located, the light-transmitting area 8 overlaps with the light-emitting unit 3. Figure 5 It is also shown that there is an array layer 14 between the base substrate 1 and the light-emitting layer 2. The array layer 14 includes a driving circuit (not shown in the figure) for driving the micro light-emitting device 4 to emit light. Of course, the structure of the micro light-emitting device 4 here is only for schematic illustration.

[0088] The light-emitting layer 2 also includes a retaining wall 13, which has a plurality of grooves, in which micro-light-emitting devices 4 are arranged. Of course, the grooves are also filled with a protective layer 30 for protecting the micro-light-emitting devices 4. It can be understood that the retaining wall 13 with grooves defines the light-emitting area of ​​each sub-light-emitting unit 12. In the direction perpendicular to the plane of the substrate 1, the grooves penetrate the retaining wall 13, and the boundaries of the grooves also correspond to the boundaries of the sub-light-emitting units 12. Of course, the retaining wall 13 can prevent light mixing between adjacent micro-light-emitting devices 4.

[0089] In some optional embodiments, referring to Fig.12 , Fig.12 yes Figure 4 In another cross-sectional view along the line A-A', the light emitting color of the micro light emitting device 4 is blue;

[0090] The display panel further includes a color conversion layer 15 located on a side of the barrier rib 13 away from the base substrate 1 .

[0091] Specifically, in a direction perpendicular to the plane where the base substrate 1 is located, the color conversion layer 15 overlaps with the micro-light-emitting device 4. The color conversion layer 15 can convert the light emitted by the micro-light-emitting device 4 into light of a desired color. The light-emitting color of the micro-light-emitting device 4 can be only blue. In order to realize the color display of the display panel, in the same light-emitting unit 3, the micro-light-emitting device 4 emitting blue light needs to be converted into red light and green light. Fig.12 The middle color conversion layer 151 converts the blue light emitted by the micro-light-emitting device 41 into red, and the color conversion layer 152 converts the blue light emitted by the micro-light-emitting device 42 into green. The blue light emitted by the micro-light-emitting device 42 does not need to be converted. Of course, the embodiment of the present invention does not limit the color of the light after conversion by the color conversion layer 15. The color of the light after conversion by the color conversion layer 15 can be determined according to actual needs.

[0092] In some optional embodiments, continue to refer to Figure 5 , the light emitting color of the micro light emitting device 4 is red, green or blue.

[0093] In this embodiment, refer to Figure 5 In the same light-emitting unit 3, the light-emitting color of the micro-light-emitting device 41 is red, the light-emitting color of the micro-light-emitting device 41 is green, and the light-emitting color of the micro-light-emitting device 41 is blue, thereby realizing color display of the display panel.

[0094] In some alternative embodiments, please refer to Fig.13 , Fig.13 1 is a schematic diagram of a planar structure of a display device provided by the present invention. The display device 1000 provided by this embodiment includes the display panel 100 provided by the above embodiment of the present invention. Fig.13 The embodiment only takes a mobile phone as an example to illustrate the display device 1000. It can be understood that the display device 1000 provided in the embodiment of the present invention can be a computer, a television, a car display device or other display device 1000 with a display function, and the present invention does not specifically limit this. The display device 1000 provided in the embodiment of the present invention has the beneficial effects of the display panel 100 provided in the embodiment of the present invention. For details, please refer to the specific description of the display panel 100 in the above embodiments, and this embodiment will not be repeated here.

[0095] It can be seen from the above embodiments that the display panel and the display device provided by the present invention achieve at least the following beneficial effects:

[0096] The display panel of the present invention has a display area, and the display area includes at least one virtual shaped edge; the light-emitting layer of the display panel includes a plurality of light-emitting units arranged along a first direction and a second direction, and the light-emitting units include micro-light-emitting devices; the light-emitting units include a plurality of first light-emitting units overlapping with the virtual shaped edge in a direction perpendicular to the plane where the substrate is located and a plurality of remaining second light-emitting units; in the same light-emitting unit row and / or the same light-emitting unit column, the brightness of the first light-emitting unit is less than the brightness of the second light-emitting unit. The light-emitting units arranged near the virtual shaped edge of the layout design are arranged in a zigzag shape, and the first light-emitting unit overlaps with the virtual shaped edge required by the customer, and the second light-emitting unit is a conventional light-emitting unit far away from the virtual shaped edge. When displaying, in the same light-emitting unit row and / or the same light-emitting unit column, the brightness of the first light-emitting unit is less than the brightness of the second light-emitting unit, so that the brightness of the first light-emitting unit near the virtual shaped edge is reduced, that is, the brightness of the virtual shaped edge area is reduced, so that the boundary of the display area is blurred, and the boundary line of the display area is closer to the virtual shaped edge in the user's visual sense, and is no longer an obvious zigzag edge of the first light-emitting unit, thereby weakening the sawtooth effect.

[0097] Although some specific embodiments of the present invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
