Technical Field

The utility model relates to the field of OLED display, in particular to an OLED pixel arrangement structure, a mask plate and a display thereof.

Background

The panel realizes the display of a color picture by superposing and mixing R, G, B three-color sub-pixels with different brightness.

The conventional LCD panel is passively lighted, and in order to make the displayed picture uniform, a standard RGB arrangement is adopted, and the size and number of sub-pixels of three colors are the same. The OLED panel is active light emitting because the light emitting materials of the three color sub-pixels have different service lives, wherein the color of blue is shortest, the color of green is second, the color of red is longest, and the characteristics of human eyes, such as strongest green light perception, second red light perception and weakest blue light perception, if the standard RGB arrangement is adopted, the phenomenon of color cast of the display picture of the panel can be caused after long-time use.
