Abstract

The invention discloses an organic electroluminescence display device, a driving method thereof and a display device. Due to the fact that in the organic electroluminescence display device, each organic electroluminescence pixel unit comprises at least two stacked and mutually insulated organic electroluminescence structures with different colors, each organic electroluminescence pixel unit can display the gray scale effect of at least two colors according to an applied signal in different frames during display. Compared with the situation in the prior art that in different frames, each organic electroluminescence pixel unit can only display the gray scale effect of one color, the organic electroluminescence display device can improve the display effect due to the fact that each organic electroluminescence pixel unit can display more colors.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an organic electroluminescence display device, a driving method thereof and a display device. Background technique [0002] Organic electroluminescence (Organic Light Emitting Diode, OLED) display device is one of the hot spots in the field of flat panel display research. Compared with liquid crystal display, OLED display device has low energy consumption, low production cost, self-luminescence, wide viewing angle and response speed. At present, in the field of flat panel displays such as mobile phones, PDAs, and digital cameras, OLED display devices have begun to replace traditional liquid crystal displays (Liquid Crystal Display, LCD). [0003] The structure of the OLED display device mainly includes: a substrate substrate, an organic electroluminescence pixel unit fabricated on the substrate substrate; such as figure 1 As shown, each organic electroluminescence pixel...
