Abstract

The invention discloses an organic electroluminescence display device, a driving method thereof and a display device. Due to the fact that at least part of pixel units are of a stacked structure, each pixel unit of the stacked structure comprises two sub-pixel unit stacked sets arranged in an adjacent mode. Each sub-pixel unit stacked set comprises at least two stacked sub-pixel units which are different in lighting color and insulated to each other. Therefore, during display, in different frames of images, the sub-pixel unit stacked sets in each pixel unit of the stacked structure can display the gray scale effect of at least two colors according to an applied signal. Compared with the situation in the prior art that in different frames of images, the gray scale effect of only one color is displayed at the position of each sub-pixel unit, the organic electroluminescence display device can improve the display effect due to the fact that the sub-pixel unit stacked sets can display more colors.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic electroluminescent display device, a driving method thereof and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) display devices are one of the hot spots in the field of flat panel display research today. Compared with liquid crystal displays, OLED display devices have low energy consumption, low production cost, self-illumination, wide viewing angle and response speed. At present, OLED display devices have begun to replace traditional Liquid Crystal Displays (LCDs) in the field of flat panel displays such as mobile phones, PDAs, and digital cameras. [0003] The structure of an OLED display device mainly includes: a base substrate, a pixel unit arranged in a matrix on the base substrate, and the pixel unit is composed of a plurality of sub-pixel units arranged on the same layer and respectively corresponding to each of the sub-pixel...
