Color display device with pixel circuits including two capacitors
Abstract:
In a pixel circuit, TFTs are connected and driven such that a threshold voltage Vth of a TFT, which is a drive transistor, can be held in a threshold holding capacitor having a capacitance value c1, voltages, including a data potential Vdata representing an image to be displayed, can be held in a data holding capacitor having a capacitance value c2, and charges in the data holding capacitor and the threshold holding capacitor are redistributed at the time of light emission. As a result, a potential obtained by multiplying the data potential Vdata by c1/(c1+c2) is provided to a gate potential of the TFT.
