Abstract
A pixel testing method is provided. The pixel testing method is adapted to measure device parameters within each pixel of a display. Before plating a lighting device into each pixel, a capacitor is formed such that one end of the capacitor is connected to an open-circuit terminal of an electronic device while the other end of the capacitor is connected to an added common line (or the original scan line or data line of the display). The parameters of the electronic device connected to the lighting device are tested through a charging/discharging of the capacitor so that all the devices within a pixel can be tested before forming organic functional layer in every pixel.
