Organic light-emitting diode display unit, driving method thereof and display device

摘要

An organic light-emitting diode display unit, a driving method thereof and a display device are disclosed. At least part of pixel units are pixel units each with a stacked structure; each pixel unit with the stacked structure includes two adjacent subpixel unit stacked groups; and each subpixel unit stacked group includes at least two subpixel units which have different emitting colors and are stacked and insulated from each other. During display of different image frames, each subpixel unit stacked group in each pixel unit with the stacked structure can display gray-scale effect of at least two colors based on applied signals. Compared with an approach that each subpixel unit can only display gray-scale effect of only one color for different image frames, the display effect can be improved.

主权项

1. An organic light-emitting diode (OLED) display unit, comprising a base substrate and a plurality of pixel units disposed on the base substrate, the plurality of pixel units including a plurality of subpixel units and pixel circuits which are respectively connected with the subpixel units in a one-to-one correspondence, wherein:
the subpixel units are OLED structures, and pixel circuits in a same pixel unit are respectively connected with different data signal lines; at least part of the pixel units are pixel units each with a stacked structure, and each of the pixel units with the stacked structure includes two adjacent subpixel unit stacked groups; each subpixel unit stacked group includes at least two subpixel units which have different emitting colors and are stacked and insulated from each other, and a quantity of subpixel units in each subpixel unit stacked group of a same pixel unit with the stacked structure is identical; in each pixel unit with the stacked structure, two subpixel units disposed in a same layer form a subpixel unit layer; and in a same pixel unit with the stacked structure, only one subpixel unit layer includes two subpixel units that have same emitting colors, and one or more other subpixel unit layers each include two subpixel units that have different emitting colors.
