Description

technical field [0001] The invention relates to a pixel structure and a repair method thereof, in particular to an organic electroluminescence display unit and a repair method thereof. Background technique [0002] The rapid progress of the multimedia society is mostly benefited from the rapid development of semiconductor devices or display devices. As far as displays are concerned, flat panel displays (FPDs) with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation have gradually become the mainstream of the market. Currently, flat panel displays on the market include Liquid Crystal Displays (LCDs), Organic Electro-Luminescence Displays (Organic Electro-Luminescence Displays), Plasma Display Panels (Plasma Display Panels, PDPs) and the like. Among them, due to the advantages of organic electroluminescent displays, such as no viewing angle limitation, low manufacturing cost, high response speed (abou...
