    Abstract: A structure and driving method for active photoelectric element that aims to every matrix-arranged pixel on the display panel. The pixel structure includes a set of first thin film diodes and a set of second thin film diodes. The first set and the second set of film diodes are connected at a node. The electrical impedances of the first set and the second set of film diodes are unsymmetrical. The first set of film diodes connects to the select lines of the pixel while the second set of film diodes connects to the select lines of the pixel on the next row, which forms a configuration that the up/down pixels share one select line. Consequently, the driving signal for the up select line of a single pixel is determined by the driving signal for the down select line of the up pixel so as to reduce the quantity of select lines.
