Abstract
The invention discloses a panel display device, multiple conductive patterns composed of multiple connected or disconnected wires are formed on the same layer of a first electrode, the conductive patterns are not connected with the first electrode, the effective decrease of resistance of a power line is achieved by connecting the conductive patterns with the power line in parallel, the voltage drop of the power line is reduced, and the display evenness of the panel display device is improved, so that the using quality is improved; the conductive patterns are connected with the power line in parallel and are not formed in the same layer, a power line breakage risk is lowered by the double layer wire arrangement, and the repairable performance of the panel display device is improved; the conductive patterns and the first electrode are formed in the same layer, so that it is unnecessary to add an additional photoetching procedure and an etching procedure, the technology is simple, the manufacturing cost is low, and the scale production is easy to achieve.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a flat panel display device whose first electrode structure can effectively reduce the voltage drop of the power line and prevent the power line from breaking. Background technique [0002] Active-matrix flat-panel display devices use thin-film transistors (English full name Thin Film Transistor, referred to as TFT) and capacitors to store signals to control the brightness and grayscale performance of pixels. Due to the long life of the panel and other characteristics, it has been highly valued in the field of display technology. [0003] Each pixel of an active matrix flat panel display device includes a switching transistor, a driving transistor, a capacitor, etc., and the power supply line in the pixel circuit supplies common power to the driving transistor and capacitor to light up the pixel. As the size of the active matrix flat panel display device increases, the ...
