Description

[Technical field]

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

[0002] Organic Light Emitting Diode (OLED) display panel is one of the research hotspots in the field of flat panel displays today. Compared with liquid crystal display panels, OLED display panels have the advantages of low energy consumption, self-luminescence, wide viewing angle and fast response speed, and have been widely used in electronic devices such as mobile phones and computers.

[0003] However, existing display panels have a problem of mismatched sub-pixel lifespans in different areas, which in turn causes the display panel to have undesirable phenomena such as uneven display. [Summary of the invention]

[0004] In view of this, embodiments of the present invention provide a display panel and a display device to improve the problem of differences in the attenuation of sub-pixel lifetimes in different regions.

[0005] In one aspect, an embodiment of the present invention provides a display panel, including:

[0006] A display area, including a first display area and an optical component setting area;

[0007] A pixel unit located in the display area, one pixel unit corresponds to a virtual quadrilateral, the pixel unit includes a first sub-pixel and four second sub-pixels, the first sub-pixel is located inside the virtual quadrilateral, and the four second sub-pixels are respectively located at four vertices of the virtual quadrilateral;

[0008] The virtual quadrilateral includes a first side, a second side, a third side and a fourth side connected in sequence, the angle between the third side and the fourth side is a first angle, and the first angle is less than or equal to 90°;

[0009] The virtual quadrilateral includes a first virtual quadrilateral and a second virtual quadrilateral, the first virtual quadrilateral is located in the first display area, the second virtual quadrilateral is located in the optical component setting area, and the light emission colors of the first sub-pixels corresponding to the first virtual quadrilateral and the second virtual quadrilateral are the same;

[0010] The first included angle of the first virtual quadrilateral is θ1, and the first included angle of the second virtual quadrilateral is θ2, where θ2>θ1.

[0011] On the other hand, an embodiment of the present invention provides a display device, including the above-mentioned display panel.

[0012] One of the above technical solutions has the following beneficial effects:

[0013] When designing the openings on the mask plate, generally, the openings corresponding to two adjacent sub-pixels of different colors (openings on different mask plates) or the openings corresponding to two adjacent sub-pixels of the same color (openings on the same mask plate) overlap. At this time, the overlapping parts of the openings need to be cut corners to form actual non-square openings. Of course, the larger the cutting area, the smaller the area of ​​the final opening, and thus the smaller the area of ​​the sub-pixel formed by evaporation.

[0014] The embodiment of the present invention makes a differentiated design for the arrangement of sub-pixels in the optical component setting area and the first display area, so that the first angle of the second virtual quadrilateral corresponding to the pixel unit in the optical component setting area is increased, and the distance between the two second sub-pixels at the vertices of the second side of the second virtual quadrilateral can be increased. At this time, the overlap between the two openings corresponding to the two second sub-pixels will also become smaller. In this way, the cut angle area of ​​this part of the opening can be reduced, and the actual area of ​​the opening after the cut angle can be increased. For example, the shape of the opening after the cut angle is closer to a square, thereby increasing the area of ​​the second sub-pixel to be evaporated, and effectively improving the total aperture ratio of the optical component setting area.

[0015] Therefore, the embodiment of the present invention can effectively weaken the total aperture ratio difference between the optical component setting area and the first display area, slow down the life attenuation of sub-pixels in the optical component setting area, and thus improve the display uniformity of the optical component setting area and the first display area.

[0016] In addition, it should be noted that after optimizing the arrangement of sub-pixels in the optical component setting area, the embodiment of the present invention can also optimize the spacing between the anodes. At this time, when the external ambient light enters the camera through the optical component setting area, the diffraction of the external ambient light between the anodes can be reduced, and the diffraction phenomenon can be significantly weakened, thereby avoiding the generation of starbursts in the image formed and optimizing the imaging effect.

[0043] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] It should be clear that the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0046] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0047] At present, sub-pixels in OLED display panels mostly adopt "RGBG" arrangement, "delta" arrangement and "diamond" arrangement.

[0048] Take the "diamond" layout as an example. Figure 1 As shown, Figure 1 Schematic diagram of an arrangement of sub-pixels in the prior art, the display panel includes a pixel unit 1', and one pixel unit 1' corresponds to a virtual square 2'. The pixel unit 1' includes five sub-pixels 3', one sub-pixel 3' is located inside the virtual square 2', and the remaining four sub-pixels 3' surrounding the sub-pixel 3' are respectively located at the four corners of the virtual square 2'. For example, see Figure 1 , the pixel unit 1′ includes a first pixel unit 11′, the first pixel unit 11′ includes two red sub-pixels 31′, two blue sub-pixels 32′ and one green sub-pixel 33′, the virtual square 2′ includes a first virtual square 21′, the green sub-pixel 33′ is located inside the first virtual square 21′, and the two red sub-pixels 31′ and two blue sub-pixels 32′ surrounding the green sub-pixel 33′ are respectively located at the four vertex corners of the first virtual square 21′.

[0049] The inventors found during the research that based on the above arrangement, when the display panel displays an image, obvious color stripes will appear at the edge of the image that deviate from the original image. Figure 1 When the green sub-pixel 33' is close to the lower edge of the display panel, an obvious green stripe will appear at the lower edge of the image displayed by the display panel, resulting in a green color edge at the lower edge of the display panel, which seriously affects the display effect.

[0050] In this regard, the embodiment of the present invention further proposes a "Windmill" arrangement based on the "diamond" arrangement. Figure 2 As shown, Figure 2 A schematic diagram of an arrangement of sub-pixels provided in an embodiment of the present invention. The arrangement is to Figure 1The virtual square 2′ corresponding to the middle pixel unit 1′ is adjusted to a virtual trapezoid 4′. For example, the virtual trapezoid 4′ includes a first virtual trapezoid 41′, the green sub-pixel 33′ is located inside the first virtual trapezoid 41′, and the two red sub-pixels 31′ and the two blue sub-pixels 32′ surrounding the green sub-pixel 33′ are respectively located at the four top corners of the first virtual trapezoid 41′.

[0051] Compared with the “diamond” arrangement, the position of the sub-pixel 3′ in the “Windmill” arrangement is offset. For example, near the lower edge of the display panel, the red sub-pixel 31′ and the blue sub-pixel 32′ are staggered in the row direction, so that the red sub-pixel 31′ is closer to the edge of the display panel, thereby using red light to weaken the green stripes at the lower edge, thereby effectively improving the color fringing phenomenon of the display panel.

[0052] For display panels with camera functions, the display area of ​​such display panels includes an optical component setting area for setting optical devices. At present, the transmittance of the optical component setting area is usually improved by reducing the pixel density in the optical component setting area, thereby improving the imaging quality. However, in this way, the total aperture ratio of the optical component setting area will be significantly smaller than the total aperture ratio of the conventional display area. For example, in one design, the average number of sub-pixels per unit inch length (Pores Per Linear Inch, PPI) in the conventional display area is 374, the total aperture ratio of the conventional display area is 23.13%, and the average number of sub-pixels per unit inch length of the optical component setting area is only 93, so that the total aperture ratio of the optical component setting area is only about 16%.

[0053] In the above structure, if the optical component setting area and the conventional display area are to achieve the same display brightness, it is necessary to increase the driving current flowing to the sub-pixels in the optical component setting area. However, this will cause the current density of the sub-pixels in the optical component setting area to be too large and the life span to decay too quickly, resulting in serious brightness reduction and color shift problems after a period of use.

[0054] Therefore, although the color edge phenomenon can be improved by applying the above-mentioned “Windmill” arrangement to this type of display panel, the display panel still has the problem of uneven display due to the large difference in sub-pixel lifespan.

[0055] To this end, the embodiment of the present invention further proposes a technical solution, which can improve the color edge phenomenon while further solving the problem of uneven display between the conventional display area 1 and the optical component setting area 3 .

[0056] like Figure 3 As shown, Figure 3A top view of a display panel provided in an embodiment of the present invention, wherein the display panel includes a display area 1, and the display area 1 includes a first display area 2 and an optical component setting area 3. The first display area 2 is a conventional display area, and the optical component setting area 3 is a display area for realizing functions such as video recording, and the optical component setting area 3 is correspondingly provided with optical components such as a camera, and specifically can be in a square, circular, or elliptical shape. In an embodiment of the present invention, the pixel density of the optical component setting area 3 can be less than the pixel density of the first display area 2 to improve the light transmittance of the optical component setting area 3.

[0057] like Figures 4 to 6 As shown, Figure 4 A schematic diagram of an arrangement of sub-pixels in the first display area 2 provided in an embodiment of the present invention, Figure 5 A schematic diagram of an arrangement of sub-pixels in the optical component setting area 3 provided in an embodiment of the present invention is shown. Figure 6 A schematic diagram of the structure of the pixel unit 4 in the first display area 2 and the optical component setting area 3 provided in an embodiment of the present invention, wherein the display panel further comprises a pixel unit 4 located in the display area 1, and one pixel unit 4 corresponds to one virtual quadrilateral 5, which can be a virtual trapezoid. The pixel unit 4 comprises a first sub-pixel 6 and four second sub-pixels 7, wherein the first sub-pixel 6 is located inside the virtual quadrilateral 5, and the four second sub-pixels 7 are respectively located at the four vertices of the virtual quadrilateral 5, wherein the first sub-pixel 6 and the second sub-pixel 7 emit light of different colors.

[0058] It should be noted that, for a sub-pixel, when the sub-pixel is considered to be located inside a virtual quadrilateral 5, the sub-pixel serves as the first sub-pixel 6 in the pixel unit 4 corresponding to the virtual quadrilateral 5; when the sub-pixel is considered to be located at the vertex of another virtual quadrilateral 5, the sub-pixel serves as the second sub-pixel 7 in the pixel unit 4 corresponding to the virtual quadrilateral 5.

[0059] The virtual quadrilateral 5 includes a first side 8, a second side 9, a third side 10 and a fourth side 11 connected in sequence, and the angle between the third side 10 and the fourth side 11 is a first angle, which is less than or equal to 90°.

[0060] The virtual quadrilateral 5 includes a first virtual quadrilateral 12 and a second virtual quadrilateral 13. The first virtual quadrilateral 12 is located in the first display area 2, and the second virtual quadrilateral 13 is located in the optical component setting area 3. In addition, the light emission colors of the first sub-pixels 6 corresponding to the first virtual quadrilateral 12 and the second virtual quadrilateral 13 are the same. The first angle of the first virtual quadrilateral 12 is θ1, and the first angle of the second virtual quadrilateral 13 is θ2, and θ2>θ1.

[0061] It should be noted that if Figure 7As shown, Figure 7 A partial cross-sectional view of a display panel provided in an embodiment of the present invention, the display panel includes a substrate 52 and a light-emitting device layer 14 located on one side of the substrate 52, the light-emitting device layer 14 includes an anode 15, a pixel definition layer 16, a light-emitting layer 17 and a cathode 18, wherein the pixel definition layer 16 includes an opening 50, and the light-emitting layer 17 is located in the opening 50 of the pixel definition layer 16. The sub-pixel described in the embodiment of the present invention can be understood as the light-emitting layer 17 arranged in the opening 50 of the pixel definition layer 16, and the position of the sub-pixel and the spacing between the sub-pixels described later are the position of the opening 50 in the pixel definition layer 16 and the spacing between the openings 50. It should be noted that in the display panel, an array layer may also be included between the substrate 52 and the light-emitting device layer 14, which is not shown in the figure.

[0062] In the manufacturing process of the display panel, sub-pixels are formed by vapor deposition using a mask plate, which has openings. Generally, the area of ​​the openings is slightly larger than the area of ​​the sub-pixels to be vapor deposited. When the display panel includes sub-pixels of multiple colors, sub-pixels of the same color are vapor deposited using the same mask plate, such as Figure 8 and Fig. 9 As shown, Figure 8 A schematic diagram of the positions of the openings and sub-pixels in the mask provided by an embodiment of the present invention, Fig. 9 A schematic diagram of a mask plate provided in an embodiment of the present invention, when the display panel includes a red sub-pixel 19, a blue sub-pixel 20 and a green sub-pixel 21, the red sub-pixel 19 is evaporated using a first mask plate 22, the first mask plate 22 includes a first opening 23, the blue sub-pixel 20 is evaporated using a second mask plate 24, the second mask plate 24 includes a second opening 25, and the green mask plate is evaporated using a third mask plate 26, the third mask plate 26 includes a third opening 27.

[0063] When designing the openings on the mask, Fig.10 As shown, Fig.10 A schematic diagram of the angle cutting of the openings in the mask plate provided in an embodiment of the present invention. Generally, in order to achieve a close arrangement of sub-pixels in a display panel, the openings corresponding to two adjacent sub-pixels of different colors (openings on different mask plates) or the openings corresponding to two adjacent sub-pixels of the same color (openings on the same mask plate) overlap. At this time, in order to avoid color mixing and achieve a close arrangement of pixels in the display panel, the overlapping parts of the openings need to be angle-cut to form actual non-square openings. Of course, the larger the angle cutting area, the smaller the area of ​​the opening finally formed, and thus the smaller the area of ​​the sub-pixel formed by vapor deposition.

[0064] The embodiment of the present invention makes a differentiated design for the arrangement of sub-pixels in the optical component setting area 3 and the first display area 2, so that the first angle of the second virtual quadrilateral 13 corresponding to the pixel unit 4 in the optical component setting area 3 is increased. Figure 6 and Fig.10 , the distance between the two second sub-pixels 7 at the vertices of the second side 9 in the second virtual quadrilateral 13 can be increased, and at this time, the overlap between the two openings corresponding to the two second sub-pixels 7 will also be reduced. In this way, the corner cutting area of ​​this opening can be reduced, and the actual area of ​​the opening after corner cutting can be increased, for example, the shape of the opening after corner cutting is made closer to a square, thereby increasing the area of ​​the evaporated second sub-pixel 7, and effectively improving the total aperture ratio of the optical component setting area 3.

[0065] Therefore, the embodiment of the present invention can effectively weaken the total aperture ratio difference between the optical component setting area 3 and the first display area 2, slow down the life attenuation of sub-pixels in the optical component setting area 3, and thereby improve the display uniformity of the optical component setting area 3 and the first display area 2.

[0066] In addition, it should be noted that, after optimizing the arrangement of sub-pixels in the optical component setting area 3 according to the embodiment of the present invention, the spacing between the anodes 15 is also optimized accordingly. At this time, when the external ambient light enters the camera through the optical component setting area 3, the diffraction of the external ambient light between the anodes 15 of the multiple sub-pixels can be reduced. For example, Fig.11 As shown, Fig.11 A diffraction comparison schematic diagram is provided for an embodiment of the present invention. When the first angle in the second virtual quadrilateral 13 is increased to 90°, the diffraction phenomenon can be significantly weakened compared to 83°, thereby avoiding the generation of starburst phenomenon in the formed image, realizing full-screen display while optimizing the imaging effect of the optical components of the under-screen camera display panel.

[0067] In a feasible implementation manner, in order to ensure that the five sub-pixels in the pixel unit 4 have an appropriate distance from each other and avoid the situation where the distance between two sub-pixels is too close and the distance between another two sub-pixels is too far, when setting θ1 and θ2, θ1 and θ2 can satisfy: 80°≤θ1≤86°, 83°≤θ2≤90°, so as to avoid color cast.

[0068] In addition, the larger the first angle is, the more conducive it is to increase the area of ​​the second sub-pixel, and the larger the aperture ratio of the pixel unit 4 is, and the longer the service life of the sub-pixel is. According to the test, it is found that, in combination with Table 1, setting θ2 between 83° and 90° can effectively improve the total aperture ratio of the optical component setting area 3.

[0069] Table 1

[0070] The first angle 90° 88° 86° 83° Aperture ratio of pixel unit (%) 22.02 21.55 20.71 19.10 Sub-pixel life (h) 475 447 420 304

[0071] In a possible implementation, combining Figure 6 , in the first virtual quadrilateral 12 , the second side 9 is the shortest side; the length of the second side 9 in the second virtual quadrilateral 13 is greater than the length of the second side 9 in the first virtual quadrilateral 12 .

[0072] Since the second side 9 in the first virtual quadrilateral 12 is the shortest side, the distance between the two second sub-pixels 7 at the vertex where the second side 9 is located is very close, and the two second sub-pixels 7 will greatly affect the size of the corner cutting area of ​​the opening in the mask. In this regard, the embodiment of the present invention increases the length of the second side 9 in the second virtual quadrilateral 13, so that the center distance between the two second sub-pixels 7 at the vertex where the second side 9 is located can be increased, which helps to optimize the corner cutting design of the opening to a greater extent, and is more conducive to realizing a sub-pixel design with a larger area.

[0073] In one possible implementation, see Figure 6 , the second side 9 in the virtual quadrilateral 5 is parallel to the fourth side 11, and the third side 10 is equal to the length of the first side 8, that is, the first virtual quadrilateral 12 and the second virtual quadrilateral 13 are isosceles trapezoids respectively. At this time, the overall arrangement of sub-pixels in the display panel is more regular and the display effect is better.

[0074] In a possible implementation, Fig.12 As shown, Fig.12 A comparative schematic diagram of the first color sub-pixel 28 in the first display area 2 and the optical component setting area 3 provided in an embodiment of the present invention. In the virtual quadrilateral 5, the first side 8 intersects with the second side 9 at the first vertex A1, and the third side 10 intersects with the second side 9 at the second vertex A2.

[0075] The second sub-pixel 7 at the first vertex A1 and / or the second vertex A2 in the first virtual quadrilateral 12 is the first color sub-pixel 28, and the second sub-pixel 7 at the first vertex A1 and / or the second vertex A2 in the second virtual quadrilateral 13 is the first color sub-pixel 28. The area of ​​the first color sub-pixel 28 corresponding to the first virtual quadrilateral 12 is S1, and the area of ​​the first color sub-pixel 28 corresponding to the second virtual quadrilateral 13 is S2, and S2>S1.

[0076] After optimizing the sub-pixel arrangement in the optical component setting area 3 , the total aperture ratio of the optical component setting area 3 can be improved by increasing the area of ​​the first color sub-pixel 28 at the first vertex A1 and / or the second vertex A2 in the second virtual quadrilateral 13 .

[0077] Optionally, the minimum distance from the first vertex A1 to the second vertex A2 in the first virtual quadrilateral 12 is smaller than the minimum distance from the first vertex A1 to the second vertex A2 in the second virtual quadrilateral 13 in the optical component setting area 3 .

[0078] Optional, see again Fig.12 In the first virtual quadrilateral 12, the distance between the first sub-pixel 6 and the first color sub-pixel 28 is P1, and in the second virtual quadrilateral 13, the distance between the first sub-pixel 6 and the first color sub-pixel 28 is P2, and P2>P1.

[0079] For the optical component setting area 3, after increasing the area of ​​the first color sub-pixel 28, the distance between the first sub-pixel 6 and the first color sub-pixel 28 is increased at the same time to avoid the first sub-pixel 6 and the first color sub-pixel 28 being too close to each other, thereby preventing the light-emitting material from drifting into the adjacent pixel definition layer opening during the evaporation process, causing color mixing or color cast.

[0080] It should be noted that see Fig.12 , the distance between the two sub-pixels mentioned above can be understood as the distance between the geometric center points of the two sub-pixels. It can be understood that the pattern actually evaporated by the sub-pixels may be an irregular pattern such as a rounded rectangle. In this case, the geometric center of the sub-pixel can be the geometric center of the irregular pattern when it is filled into a regular pattern. For example, if the shape of the sub-pixel is a rounded rectangle, then the geometric center of the sub-pixel is the geometric center of the rectangle when the rounded rectangle is filled into a rectangle. Alternatively, the distance between the two sub-pixels can also be understood as the maximum distance between the edges of the two sub-pixels.

[0081] In a possible implementation, Fig.13 As shown, Fig.13 A structural schematic diagram of a first virtual quadrilateral 12 and a second virtual quadrilateral 13 provided in an embodiment of the present invention, in the virtual quadrilateral 5, the center point of the first side 8 and the third side 10 is the first center point O1, and the center point of the second side 9 and the fourth side 11 is the second center point O2.

[0082] In the first virtual quadrilateral 12 and the second virtual quadrilateral 13, the vertical distance from the first center point O1 to the second side 9 and the vertical distance from the first center point O1 to the fourth side 11 are both L1, and the distance from the first center point O1 to the second center point O2 is both L2. That is, after the two center points and the two second center points O2 in the second virtual quadrilateral 13 are translated as a whole, they coincide with the two first center points O1 and the two second center points O2 in the first virtual quadrilateral 12.

[0083] Combined with the above description of the "diamond" arrangement, in the embodiment of the present invention, Fig.14As shown, Fig.14 Another structural schematic diagram of the first virtual quadrilateral 12 and the second virtual quadrilateral 13 provided in an embodiment of the present invention, the first virtual quadrilateral 12 can be constructed on the basis of the virtual square 2' in the "diamond" arrangement. For example, under the premise of ensuring that the position of the center point of each side in the virtual square 2' remains unchanged, the two opposite sides in the virtual square 2' are adjusted to construct a first virtual quadrilateral 12 in the form of an isosceles trapezoid, thereby making the position of the sub-pixel in the first display area 2 slightly offset compared to the position of the sub-pixel in the "diamond" arrangement, and achieving the effect of improving the color edge without affecting the overall arrangement. At this time, the center points of the four sides in the first virtual quadrilateral 12 coincide with the center points of the four sides in the virtual square 2'.

[0084] When the first angle of the second virtual quadrilateral 13 is adjusted by adjusting the position of the second sub-pixel 7 corresponding to the second virtual quadrilateral 13, the position change of the second sub-pixel 7 corresponding to the second virtual quadrilateral 13 may also follow the above-mentioned design concept, that is, no matter how the positions of the four second sub-pixels 7 at the vertex corners of the second virtual quadrilateral 13 change, it is satisfied that the center points of the four sides of the second virtual quadrilateral 13 coincide with the center points of the four sides of the virtual square, that is, the center points of the four sides of the second virtual quadrilateral 13 coincide with the center points of the four sides of the first virtual quadrilateral 12, so that the arrangement of the sub-pixels in the optical component setting area 3 and the arrangement of the sub-pixels in the first display area 2 follow the same design concept, while achieving an improvement in the total aperture ratio of the optical component setting area 3, the regularity of the overall arrangement of the sub-pixels of the display panel is improved.

[0085] It should be noted that, again, see Fig.14 , the second virtual quadrilateral 13 is translated, and when the center points of the four sides of the second virtual quadrilateral 13 coincide with the center points of the four sides of the first virtual quadrilateral 12, the distance between any vertex in the second virtual quadrilateral 13 and the vertex of the first virtual quadrilateral 12 closest to it is L.

[0086] In a possible implementation, Fig.15 As shown, Fig.15 A schematic diagram comparing the positions of the second sub-pixels 7 corresponding to the first virtual quadrilateral 12 and the second virtual quadrilateral 13 provided in an embodiment of the present invention. In the virtual quadrilateral 5, the first side 8 intersects with the second side 9 at the first vertex A1, the second side 9 intersects with the third side 10 at the second vertex A2, the third side 10 intersects with the fourth side 11 at the third vertex A3, and the fourth side 11 intersects with the first side 8 at the fourth vertex A4.

[0087] In the first virtual quadrilateral 12, the distance between the two second sub-pixels 7 at the first vertex A1 and the second vertex A2 is P31, and the distance between the two second sub-pixels 7 at the third vertex A3 and the fourth vertex A4 is P31, which can also be understood as the length of the second side 9 in the first virtual quadrilateral 12 is P31, and the length of the fourth side 11 is P32. In the second virtual quadrilateral 13, the distance between the two second sub-pixels 7 at the first vertex A1 and the second vertex A2 is P41, and the distance between the two second sub-pixels 7 at the third vertex A3 and the fourth vertex A4 is P42, which can also be understood as the length of the second side 9 in the second virtual quadrilateral 13 is P41, and the length of the fourth side 11 is P42, P41>P31 and P42<P32.

[0088] In this setting, compared with the first virtual quadrilateral 12, by moving the two second sub-pixels 7 at the vertices of the second side 9 in the second virtual quadrilateral 13 in opposite directions and moving the two second sub-pixels 7 at the vertices of the fourth side 11 in the direction of approaching each other, it is possible to better achieve that the two center points and the two second center points O2 in the second virtual quadrilateral 13 are coincident with the two first center points O1 and the two second center points O2 in the first virtual quadrilateral 12 after the overall translation, so as to better realize the above-mentioned design concept for the second virtual quadrilateral 13.

[0089] Further, see again Fig.15 In the second virtual quadrilateral 13, the distance between the first sub-pixel 6 and the second sub-pixel 7 at the first vertex A1 is P5, and the distance between the first sub-pixel 6 and the second sub-pixel 7 at the second vertex A2 is P6, P5=P6. At this time, the distances between the first sub-pixel 6 inside the second virtual quadrilateral 13 and the two second sub-pixels 7 at the vertices of the second side 9 are equal, especially when the two second sub-pixels 7 at the vertices of the second side 9 are sub-pixels of different colors, the first sub-pixel 6 and the two second sub-pixels 7 of different colors can be spaced the same distance apart to avoid color cast.

[0090] In a possible implementation, Fig.16 As shown, Fig.16A schematic diagram of the position of the first sub-pixel 6 provided in an embodiment of the present invention, in the second virtual quadrilateral 13, the geometric center of the first sub-pixel 6 coincides with the center point of the diagonal of the virtual quadrilateral 5. At this time, the first sub-pixel 6 is located in the middle position of the virtual quadrilateral 5. Taking the virtual quadrilateral 5 as an isosceles trapezoid as an example, the distances between the first sub-pixel 6 and the two second sub-pixels 7 at the first vertex A1 and the second vertex A2 are equal, and the distances between the first sub-pixel 6 and the second sub-pixels 7 at the third vertex A3 and the fourth vertex A4 are also equal. At the same time, the positional relationship between the first sub-pixel 6 and each sub-pixel at the four vertices of the virtual quadrilateral is taken into account, so that color cast can be avoided to a greater extent.

[0091] In a possible implementation, combining Figures 4 to 6 , the pixel unit 4 includes a first pixel unit 31, the first pixel unit 31 corresponds to the first type virtual quadrilateral 32, in which the first sub-pixel 6 is a green sub-pixel 21, the two second sub-pixels 7 are red sub-pixels 19, and the two second sub-pixels 7 are blue sub-pixels 20, wherein the two red sub-pixels 19 are located at the two vertex angles where a diagonal line of the first type virtual quadrilateral 32 is located, and the two blue sub-pixels 20 are located at the two vertex angles where another diagonal line of the first type virtual quadrilateral 32 is located. The first angle of the first type virtual quadrilateral 32 in the first display area 2 is θ11, and the first angle of the first type virtual quadrilateral 32 in the optical component setting area 3 is θ21, and θ21>θ11.

[0092] At this time, by adjusting the first angle of the first type of virtual quadrilateral 32 in the optical component setting area 3, the distance between the red sub-pixel 19 and the blue sub-pixel 20 at the vertex of the second side 9 in the first type of virtual quadrilateral 32 can be increased, so that when designing the openings in the first mask plate 22 and the second mask plate 24, the cut angle area corresponding to this part of the opening can be reduced, thereby increasing the area of ​​the red sub-pixel 19 and the blue sub-pixel 20 that can be evaporated, and improving the total aperture ratio of the optical component setting area 3.

[0093] In a possible implementation, combining Figure 4 and Figure 5 ,like Fig.17 As shown, Fig.17 Another structural schematic diagram of the pixel unit 4 in the first display area 2 and the optical component setting area 3 provided by an embodiment of the present invention, the pixel unit 4 includes a second pixel unit 33, the second pixel unit 33 corresponds to the second type of virtual quadrilateral 34, in the second pixel unit 33, the first sub-pixel 6 is a blue sub-pixel 20, and the four second sub-pixels 7 are all green sub-pixels 21. The first angle of the second type of virtual quadrilateral 34 in the first display area 2 is θ12, and the first angle of the second type of virtual quadrilateral 34 in the optical component setting area 3 is θ22, θ22>θ12.

[0094] At this time, by adjusting the first angle of the second type virtual quadrilateral 34 in the optical component setting area 3, the distance between the two green sub-pixels 21 at the vertices of the second side 9 in the second type virtual quadrilateral 34 can be increased. Therefore, when designing the opening of the third mask plate 26, the cutting angle area of ​​this part of the opening can be reduced, while taking into account the evaporation yield and increasing the area of ​​the green sub-pixel 21 that can be evaporated, thereby improving the total aperture ratio of the optical component setting area 3.

[0095] In a possible implementation, combining Figure 4 and Figure 5 ,like Fig.18 As shown, Fig.18 It is another structural schematic diagram of the pixel unit 4 in the first display area 2 and the optical component setting area 3 provided by the embodiment of the present invention, the pixel unit 4 includes a third pixel unit 35, the third pixel unit 35 corresponds to the third type of virtual quadrilateral 36, in the third pixel unit 35, the first sub-pixel 6 is a red sub-pixel 19, and the four second sub-pixels 7 are all green sub-pixels 21. The first angle of the third type of virtual quadrilateral 36 in the first display area 2 is θ13, and the first angle of the third type of virtual quadrilateral 36 in the optical component setting area 3 is θ23, and θ23>θ13.

[0096] At this time, by adjusting the first angle of the third type of virtual quadrilateral 36 in the optical component setting area 3, the distance between the two green sub-pixels 21 at the vertices of the second side 9 in the third type of virtual quadrilateral 36 can be increased, so that when designing the opening of the third mask plate 26, the cutting angle area of ​​this part of the opening can be reduced, thereby increasing the area of ​​the green sub-pixel 21 that can be evaporated, and improving the total aperture ratio of the optical component setting area 3.

[0097] In a feasible embodiment, among multiple virtual quadrilaterals 5, the virtual quadrilaterals 5 with the same light emitting color of the first sub-pixel 6 are the same type of virtual quadrilaterals 5, the first angles of the same type of virtual quadrilaterals 5 in the first display area 2 are the same, and / or the first angles of the same type of virtual quadrilaterals 5 in the optical component setting area 3 are the same.

[0098] Specifically, in the first display area 2, the first angles of the plurality of first-type virtual quadrilaterals 32 are the same, the angles of the plurality of second-type virtual quadrilaterals 34 are the same, and the angles of the plurality of third-type virtual quadrilaterals 36 are the same. In the optical component setting area 3, the first angles of the plurality of first-type virtual quadrilaterals 32 are the same, the angles of the plurality of second-type virtual quadrilaterals 34 are the same, and the angles of the plurality of third-type virtual quadrilaterals 36 are the same, so as to improve the arrangement regularity of the sub-pixels and the display effect.

[0099] In a possible implementation, Fig.19 and Fig. 20 As shown, Fig.19 Another top view of a display panel provided by an embodiment of the present invention, Fig. 20 A schematic diagram of a structure of a transition zone 37 provided in an embodiment of the present invention, wherein the display area 1 further includes a transition zone 37 surrounding the optical setting area. The virtual quadrilateral 5 further includes a third virtual quadrilateral 38, which is located in the transition zone 37, and the light emission colors of the first sub-pixel 6 corresponding to the third virtual quadrilateral 38 and the first virtual quadrilateral 12 are the same. The first angle in the third virtual quadrilateral 38 is θ3, and θ1<θ3<θ2.

[0100] In this setting, by making the first angle of the third virtual quadrilateral 38 in the transition zone 37 larger than the first angle of the first virtual quadrilateral 12 in the first display area 2, and smaller than the first angle of the second virtual quadrilateral 13 in the optical component setting area 3, for sub-pixels of the same color, it helps to achieve the transition of the sub-pixel area in the first display area 2, the transition zone 37 to the optical component setting area 3, so that the life span of the sub-pixels in the entire display area 1 decays evenly, avoiding color cast in local areas.

[0101] Optionally, 2°≤θ3-θ1≤5°, 2°≤θ2-θ3≤5°.

[0102] If the difference between θ3 and θ1 and the difference between θ2 and θ3 are too small, the arrangement difference and area difference of the sub-pixels in the first display area 2, the transition area 37 and the optical component setting area 3 are very small, and it is difficult for the transition area 37 to achieve a good transition effect. If the difference between θ3 and θ1 and the difference between θ2 and θ3 are too large, the difference between θ1 and θ2 will be too large, which will cause the arrangement difference of the sub-pixels in the first display area 2 and the optical component setting area 3 to be too large, thereby affecting the display effect.

[0103] To this end, by setting θ3-θ1 and θ2-θ3 between 2° and 5°, it is possible to optimize the sub-pixel arrangement in the first display area 2 and the optical component setting area 3, and also to utilize the transition area 37 to better weaken the display difference between the first display area 2 and the optical component setting area 3.

[0104] In order to achieve a smoother transition, θ3-θ1=θ2-θ3 can be further set.

[0105] It should be noted that the display panel further includes a pixel circuit electrically connected to the sub-pixel. Fig.21 As shown, Fig.21Another structural schematic diagram of the transition area 37 provided in an embodiment of the present invention, the transition area 37 includes a first pixel circuit 39, and the first pixel circuit 39 is electrically connected to the sub-pixel 40 in the optical component setting area 3. That is to say, the above-mentioned setting method sets at least part of the pixel circuits electrically connected to the sub-pixel 40 in the optical component setting area 3 in the transition area 37, thereby reducing the number of pixel circuits required to be set in the optical component setting area 3, and even eliminating the need to set pixel circuits in the optical component setting area 3, thereby increasing the light transmittance of the optical component setting area 3 to a greater extent and optimizing the imaging quality.

[0106] Or, in another feasible implementation, as Fig. 22 As shown, Fig. 22 This is another structural schematic diagram of the optical component setting area 3 provided in an embodiment of the present invention, wherein the optical component setting area 3 includes a second pixel circuit 51, and the second pixel circuit 51 is electrically connected to the sub-pixel 40 in the optical component setting area 3. That is to say, in the above-mentioned setting mode, the pixel circuit electrically connected to the sub-pixel 40 in the optical component setting area 3 is directly set in the optical component setting area 3, and at this time, the connection distance between this part of the sub-pixel 40 and the second pixel circuit 51 can be reduced, thereby reducing the attenuation of the signal during the transmission process.

[0107] In a possible implementation, Fig.23 As shown, Fig.23 A schematic diagram of the structure of sub-pixels in the optical component setting area 3 provided in an embodiment of the present invention, in which the first sub-pixel 6 and the second sub-pixel 7 are circular in shape in the pixel unit 4 of the optical component setting area 3. Compared with the sub-pixels in the shape of squares, the sub-pixels in the optical component setting area 3 are designed to be circular, which can avoid the regular stripe gaps between the anodes 15 corresponding to the sub-pixels, thereby effectively improving the diffraction generated when the external ambient light is incident from the optical component setting area 3, and avoiding the starburst phenomenon during imaging.

[0108] It should be noted that in other optional embodiments of the present invention, Fig.24 As shown, Fig.24 This is another top view of the display panel provided by the embodiment of the present invention. To improve the display effect of the optical component setting area 3, the pixel density in the optical component setting area 3 can be set to be the same as the pixel density in the first display area 2. At this time, to improve the light transmittance of the optical component setting area 3, the area of ​​a single sub-pixel in the optical component setting area 3 can be reduced.

[0109] In this setting mode, the arrangement space of the sub-pixels in the optical component setting area 3 can still be more reasonably optimized by adjusting the size of the first angle θ12 in the second virtual quadrilateral 13 in the optical component setting area 3, so as to allocate part of the space to the sub-pixels with the most serious brightness attenuation, so as to increase the setting area of ​​these sub-pixels and improve their display life. Exemplarily, compared with the first type of virtual quadrilateral 32 in the first display area 2, the first angle of the first type of virtual quadrilateral 32 in the optical component setting area 3 can be increased to allocate a larger setting space for the blue sub-pixel 20, thereby increasing the setting area of ​​the blue sub-pixel 20 to a certain extent, reducing the life attenuation rate of the blue sub-pixel 20, and improving the life consistency between the blue sub-pixel 20 and the red sub-pixel 19 and the green sub-pixel 21.

[0110] Based on the same inventive concept, an embodiment of the present invention provides a display device, such as Fig.25 As shown, Fig.25 1 is a schematic diagram of a structure of a display device provided in an embodiment of the present invention, and the display device includes the above-mentioned display panel 100.
