According to the invention, the third sub-pixel 203 is arranged at the central position between the first pixel pair 210 and the second pixel pair 220, so that two first sub-pixels 201, two second sub-pixels and at least one third sub-pixel jointly form a pixel group 100, the pixel structure is arranged, the adjacent same-color sub-pixels are integrated together as much as possible, the smaller pixel size can be realized through an evaporation process or a printing process, and the resolution of the display panel can be improved under the condition of the same process conditions; and the same-color sub-pixels form a straight line, which is beneficial to the manufacture of the display panel and improves the process efficiency.
Optionally, with continued reference to fig. 1 and fig. 2, the pixel group 100 is rectangular, the first subpixel 201 and the second subpixel 202 are pentagonal, the first subpixel 201 and the second subpixel 201 are located at a vertex angle of the rectangle, a vertex angle at which the pentagonal of the first subpixel 201 or the second subpixel 202 coincides with the rectangular of the pixel group 100 is a first vertex angle a, an opposite side of the first vertex angle a is a first side 700 of the pentagonal, the third subpixel 203 is square, and four sides of the square of the third subpixel are respectively opposite to the first side 700.
The invention obtains a pixel group 100 structure with compact arrangement by arranging the first side 700 of the pentagon of the first sub-pixel 201 and the second sub-pixel 202 opposite to the side of the square of the third sub-pixel 203. On one hand, the aperture ratio of the first sub-pixel 201 and the second sub-pixel 202 is increased while the resolution of the display panel is increased; on the other hand, the edges of the adjacent sub-pixels can be embedded together through the arrangement, effective color mixing of the adjacent sub-pixels is facilitated, and the display quality of the display panel is improved.
It should be noted that the sub-pixels in the present application may also have other shapes, such as triangle, quadrangle, hexagon, etc., and the present application does not specifically limit this, as long as the display panel with high PPI can be formed by the pixel arrangement provided by the present invention, which is consistent with the description of the present application.
Optionally, with reference to fig. 3, in the same pixel group 100, the total area of the first sub-pixels 201 is equal to the total area of the second sub-pixels 202, and the total area of the second sub-pixels 202 is equal to the total area of the third sub-pixels 203. Specifically, in fig. 3, the first pixel group 101 includes two first sub-pixels 201, and the areas of the first sub-pixels 201 are S11 and S12, respectively; two second sub-pixels 202, the areas of the second sub-pixels 202 being S21 and S22, respectively; and a third subpixel 203, wherein the area of the third subpixel 203 is S3, and then S11+ S12 is S21+ S22 is S3. It can be understood that, a pixel group 100 constitutes a complete display pixel, for example, the first sub-pixel 201 is red, the second sub-pixel 202 is blue, and the third sub-pixel 203 is green, and by setting the total area of the first, second, and third sub-pixels (201/202/203) in the same pixel group 100 to be the same, it is beneficial to uniform display of the display panel and to improve the display quality of the display panel.
It should be noted that the above embodiment is only described by taking the case that one pixel group 100 includes one third sub-pixel 203, and in some other embodiments, there may be a plurality of third sub-pixels 203 included in one pixel group 100.
Alternatively, referring to fig. 1 and fig. 4, the four same-color sub-pixels adjacent to each other are located at the center of the four adjacent pixel groups 100, and the four same-color sub-pixels adjacent to each other form a same-color sub-pixel unit 400, and the same-color sub-pixel unit 400 is octagonal. It should be noted that, in the present application, four pixel groups adjacent to each other may be that pixel group 100/1 is adjacent to pixel group 100/2 and pixel group 100/4, pixel group 100/2 is adjacent to pixel group 100/1 and pixel group 100/3, and pixel group 100/3 is adjacent to pixel group 100/2 and pixel group 100/4. Illustratively, four second sub-pixels 202 adjacent to each other constitute a same-color sub-pixel unit 400, but of course, four first sub-pixels 201 adjacent to each other may constitute a same-color sub-pixel unit. In the manufacturing process of the specific display panel, the same-color sub-pixels adjacent to each other are concentrated together, so that the concentrated evaporation of the same-color area or the continuous printing of the same-color area is facilitated.
Optionally, with continued reference to fig. 4, the side length d of the octagon of the same-color sub-pixel unit 400 is greater than 5 μm. It can be understood that when the sub-pixel is manufactured by adopting the printing process, in the process of continuous printing, ink is dripped into the corresponding printing area through the movement of the printing nozzle, and the sub-pixel unit with the same color is obtained. When the side length of the same-color sub-pixel unit 400 is greater than 5 micrometers, the implementation of linear continuous printing is facilitated, and the difficulty of the preparation process of the display panel is reduced; and the thickness of ink falling into all the positions in each sub-pixel can be controlled to be the same by controlling the movement speed of the printing nozzle, so that the display uniformity of the display panel is improved.
Optionally, please refer to fig. 5-7, fig. 5 is a schematic structural diagram of a display panel according to the present invention; FIG. 6 is a schematic cross-sectional view along AA' of the display panel shown in FIG. 5; fig. 7 is a schematic cross-sectional view of the display panel of fig. 5 along BB'.
Specifically, the display panel 500 includes a substrate and a pixel defining layer 520 on one side of the substrate; the pixel defining layer 520 includes a plurality of grooves 510 arranged in an array, and adjacent sub-pixels with the same color are located in the same groove 510. It can be understood that the same-color sub-pixels adjacent to each other and having the same color form the same-color pixel unit 400, and the same-color sub-pixel unit includes a first same-color sub-pixel unit 401 and a second same-color sub-pixel unit 402, wherein the same-color sub-pixel units are located in the same column, and in the process of manufacturing the display panel, the same-color sub-pixel units 400 located in the same column are located in the same groove 510. Optionally, the groove 510 includes a plurality of vias 540, the vias 540 correspond to the sub-pixels one by one, and an orthographic projection of the via 540 on the substrate 530 coincides with an orthographic projection of the corresponding sub-pixel on the substrate 530. Optionally, the thickness of the pixel defining layer 520 between adjacent grooves 510 is greater than the thickness of the pixel defining layer 520 within the grooves 510.
The via 540 in this embodiment penetrates through the pixel defining layer to expose a corresponding anode electrode (not shown in the figure), and the liquid organic light emitting material dripped in the via is in direct contact with the anode electrode to emit light under the control of an electric field formed between the anode electrode and a cathode layer located at a side of the pixel defining layer away from the substrate.
In this embodiment, the plurality of same-color sub-pixels in different pixel groups are arranged adjacently and concentratedly, so that the organic light emitting function layers of the plurality of sub-pixels in the same-color sub-pixel unit 400 in the organic light emitting display substrate can correspond to the same evaporation hole or the same organic light emitting material droplet and are formed in the same process step, thereby increasing the number of sub-pixels corresponding to the evaporation hole and the organic light emitting material droplet, improving the resolution of the display substrate, and solving the problem that the pixel density cannot be continuously improved due to the fact that the sizes of the evaporation hole and the organic light emitting material droplet cannot be reduced under the influence of process limits.
And the same-color sub-pixel units 400 with the same color are located on the same straight line, when the sub-pixels are formed by adopting a printing process, the drippers of the printing equipment for outputting the liquid organic light-emitting material can make linear motion along the extending direction of the groove 510, the liquid organic light-emitting material is kept continuously output in the process, the liquid organic light-emitting material dripped onto the pixel limiting layer between the through holes can be converged into the adjacent through holes along the inclined hydrophobic surfaces, the printing difficulty of the liquid organic light-emitting material is reduced, and the uniformity of the liquid organic light-emitting material is improved.
The pixel defining layer 520 between the adjacent via holes 540 has a structure with a high middle and two low sides in the extending direction of the groove 510, so that the liquid organic light emitting material directly dripped in the region can be converged into the adjacent via holes along the surface of the pixel defining layer. On the other hand, the structure with high middle and low two sides enables the middle position to have no platform, and the liquid organic luminescent material is prevented from staying on the platform.
It should be noted that, in the embodiment of the present invention, the sub-pixels with the same color in the groove 510 are separated by the pixel defining layer, so that the crosstalk influence of the adjacent sub-pixels is avoided on the basis of ensuring the high PPI of the array substrate. In some other embodiments, the sub-pixels in the same-color sub-pixel unit 400 may also be separated by an inorganic material, or no pixel definition layer is disposed in the same-color sub-pixel unit 400, and the sub-pixels are separated by an anode, so that the arrangement of the sub-pixels is more compact, which is beneficial to realize high PPI display.
