An organic electroluminescence display device, its driving method and related device

Abstract

The invention discloses an organic electroluminescent display device, its driving method and related devices, since each pixel unit group includes first sub-pixels arranged adjacently along the first direction and respectively including three sub-pixels with different colors The unit group and the second sub-pixel unit group; and each sub-pixel in the first sub-pixel unit group and each sub-pixel in the second word pixel unit group are arranged in a dislocation along the second direction, and any sub-pixel on the substrate The colors of each are different from the colors of other sub-pixels adjacent to the sub-pixel. Therefore, it is ensured that the sub-pixels of the same color on the substrate are regularly staggered, and then when making the corresponding metal mask, the sub-pixels of the same color correspond to the adjacent opening regions in the metal mask. The distance between them is relatively large, which increases the strength of the metal mask, which is conducive to the manufacture of small-sized sub-pixels, and thus can improve the resolution of the organic electroluminescent display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic electroluminescence display device, a driving method thereof and related devices. 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 the OLED display device mainly includes: a base substrate, and pixels arranged in a matrix on the base substrate. Wherein, each pixel generally uses an organic material to form an organic electroluminescent structure at a corresponding pixel position on the arr...

Problems solved by technology

Although this method can make the shape of the metal strips in the metal mask plate more stable, in order to avoid the shadowing effect of the metal bridge on the sub-pixel during evaporation, the sub-pixel and the metal Sufficient distance must be kept between the bridges, resulting in a reduction in the size of the sub-pixel, which affects the aperture ratio of the OLED display device
