Description

technical field [0001] The invention relates to the display field, in particular to an organic light-emitting display device. Background technique [0002] An organic light-emitting display device, that is, an organic light-emitting diode (Organic Light-Emitting Diode, OLED) display device, is also called an organic electroluminescence display (OELD) device. Because of its thinness, power saving and other characteristics, it has many incomparable advantages of liquid crystal displays, so it has always been favored by people in the industry. The OLED display device is different from the traditional liquid crystal display in that it does not require a backlight. It uses a very thin coating of organic materials on a glass substrate. When an electric current passes through, these organic materials will emit light. Moreover, the OLED display screen can be made lighter and thinner, has a larger viewing angle, and can significantly save power. [0003] There are two kinds of colo...
