Embodiment 1

[0037] Please refer to figure 1 , the pixel arrangement structure 01 provided by the embodiment of the present invention includes a plurality of first repeating units 10 and a plurality of second repeating units 20 alternately arranged in the row direction X and the column direction Y, the first repeating units 10 and the second Each repeating unit 20 includes a first sub-pixel 011 , a second sub-pixel 012 , a third sub-pixel 013 and a fourth sub-pixel 014 . As an example, figure 1 Only a partial area of ​​the pixel arrangement structure 01 provided in the embodiment of the present invention is intercepted; in the actual pixel arrangement structure 01, the number of first repeating units 10 may be M, where M is a positive integer not less than 1, The quantity of the second repeating unit 20 can be the same as the quantity of the first repeating unit 10, which is also M, and M is a positive integer not less than 1, and can also be one less than the quantity of the first repeat...

Embodiment 2

[0060] Please refer to Figure 4 , the pixel arrangement structure 02 provided by the embodiment of the present invention includes a plurality of first repeating units 11 and a plurality of second repeating units 21 alternately arranged in the row direction X and the column direction Y, the first repeating units 11 and the second Each repeating unit 21 includes a first sub-pixel 021 , a second sub-pixel 022 , a third sub-pixel 023 and a fourth sub-pixel 024 . As an example, Figure 4 Only a partial area of ​​the pixel arrangement structure 02 provided in the embodiment of the present invention is intercepted; in the actual pixel arrangement structure 02, the number of first repeating units 11 may be N, where N is a positive integer not less than 1, The quantity of the second repeating unit 21 can be the same as the quantity of the first repeating unit 11, which is also N, and N is a positive integer not less than 1, and can also be one less than the quantity of the first repe...

Embodiment 3

[0089] Please refer to Figure 8 , the embodiment of the present invention provides a high-precision metal mask 03, the high-precision metal mask 03 includes openings of three shapes: the opening 311 corresponding to the second sub-pixel 012, the opening corresponding to the first sub-pixel 011 312 and an opening 313 corresponding to the third sub-pixel 013 or the fourth sub-pixel 014 . Since the third sub-pixel 013 and the fourth sub-pixel 014 have the same shape, the third sub-pixel 013 and the fourth sub-pixel 014 can share the opening 313 . As a preferred implementation manner, the shapes and positions of the openings corresponding to the sub-pixels are the same, so that during the evaporation process, the accuracy of the evaporation of the sub-pixels can be effectively improved. It can be understood that the above-mentioned openings can be set on the same mask plate, or can be set on different mask plates.

[0090] It is worth noting that, in the pixel arrangement struc...

Abstract

The invention provides a pixel arrangement structure, a high-precision metal mask plate and a display panel. The pixel arrangement structure provided by the invention comprises a plurality of first repeating units and a plurality of second repeating units which are alternately arranged in the row direction and the column direction, wherein each of the first repeating unit and the second repeatingunit comprises a first sub-pixel, a second sub-pixel, a third sub-pixel and a fourth sub-pixel; each of the first sub-pixels and the second sub-pixels is of an arc structure, and the first sub-pixelsand the second sub-pixels are the same in size; the two first sub-pixels and the two second sub-pixels are arranged around the corresponding third sub-pixel; and the fourth sub-pixel is arranged on one side, far away from the third sub-pixel, of any one first sub-pixel or any one second sub-pixel. By means of the arrangement, the pixel arrangement structure can be in the shape with the arc-shapededge, and therefore the sawtooth feeling generated during special-shaped display of the display panel is reduced; while the display effect is ensured, the adjacent sub-pixels can be shared, and the display resolution is further effectively improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel arrangement structure, a high-precision metal mask plate and a display panel. Background technique [0002] OLED (Organic light-emitting diode, organic light-emitting diode) display panel has been widely promoted due to its advantages of low power consumption, high saturation, wide viewing angle, thin thickness, and flexibility. With the maturity of the market and the progress of the industry, OLED display panels have gradually evolved from traditional rectangular panels to special-shaped display panels, such as: circular watches, car display screens, etc. However, most of the sub-pixels currently used in OLED display panels are mostly rectangular in shape, and the corners of the pixel arrangement structure composed of rectangular sub-pixels are straight. Therefore, when rectangular sub-pixels form special-shaped images, they are easily restricted by the shape of the pix...
