The invention relates to an active matrix organic LED (light-emitting diode) pixel structure and a manufacturing method thereof. The active matrix organic LED pixel structure comprises a grid wire, a common electrode wire, a signal wire and a power wire formed on a substrate, a first thin-film transistor serving as an addressing component, and a second thin-film transistor for controlling the organic LED, wherein the grid wire, the common electrode sire, the signal wire and / or the power wire are connected to a strip-shaped electrode for avoiding the disconnection; and the strip-shaped electrode comprises a first strip-shaped electrode, a second strip-shaped electrode, a third strip-shaped electrode and / or a fourth strip-shaped electrode. By arranging the strip-shaped electrode in a pixel region and forming a comb-shaped structure by the strip-shaped electrode, the grid wire, the common electrode sire, the signal wire and / or the power wire, the invention can reduce the probability of disconnection and improve the yield.
Description
technical field [0001] The invention relates to a flat panel display device and a manufacturing method thereof, in particular to an active matrix organic light emitting diode pixel structure and a manufacturing method thereof. Background technique [0002] Active Matrix Organic Light Emitting Diode (AMOLED) is a new type of flat panel display device. Compared with liquid crystal display (LCD), AMOLED has better viewing angle and contrast ratio because of its light-emitting function. Because it does not need a backlight device that provides an external light source, AMOLED has the advantages of small size, light weight, and low power consumption; due to the low DC drive, AMOLED has the advantage of fast response; due to the use of solid materials instead of LCD Therefore, AMOLED is relatively stable under external impact and can work in a wide temperature range; AMOLED also has the advantages of low production cost. [0003] Currently, the prior art active matrix organic lig...
