Abstract

The invention discloses an organic electroluminescence display appliance and a driving method and a related device thereof. Each pixel unit group comprises a first pixel unit group and a second pixel unit group which are adjacently arranged along a first direction and are respectively provided with three sub pixels different in colors; all the sub pixels in the first pixel unit group and all the sub pixels in the second pixel unit group are arranged in a staggered manner along a second direction; and the color of any one sub pixel on a substrate is different from the colors of other sub pixels adjacent to the sub pixel. Thus, the sub pixels in the same color on the substrate are regularly arranged in a staggered manner. Therefore, when a corresponding metal mask plate is manufactured, a distance between adjacent opening areas in the metal mask plate corresponding to the sub pixels in the same color is relatively enlarged, so that the strength of the metal mask plate is enhanced, and the manufacturing of the sub pixels in small sizes can be facilitated. As a result, the resolution ratio of the organic electroluminescence display appliance is improved.

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...
