Abstract:
1. A structure for active photoelectric element, which aims to every matrix-arranged pixel on the display panel, comprising: a common electrode, a pixel electrode, and a liquid crystal layer between the two electrodes, which forms a pixel storage capacitor, and the common electrode connects to a data line; a set of first thin film diodes and a set of second thin film diodes, the first set of film diodes and the second set of film diode connected at a node, the pixel electrode also connecting to the node, and the electrical impedance of the first set of film diodes and the electrical impedance of the second set of film diode being different; and a select line and the data line being perpendicular to each other, wherein the other terminal of the first set of film diode connects to the select line while the other terminal of the second set of film diodes connects to the select line of the pixel on the next row, which forms a configuration that the up/down pixels share one select line; wherein the second set of thin film diodes is 1˜5 times of the electrical impedance of the first set of thin film diodes.
