摘要： In a display in which pixel circuits each including a drive transistor, switching transistors and a capacitor are arranged in rows and columns, two-stage mobility correction is implemented in which mobility correction with an intermediate grayscale level (gray level) is executed before mobility correction is executed with an input signal (Vsig) level being written to the gate of the drive transistor when the switching transistor is in the conducting state. Thus, even if the mobility correction period is constant, mobility correction can be implemented for all the grayscales within the mobility correction period. This feature allows achievement of a uniform image quality free from streaks and unevenness attributed to variation in the mobility from pixel to pixel.

摘要： It is aimed to increase efficiency and simplification of a pixel circuit having a threshold voltage correcting function. A sampling transistor Tr1 is brought into conduction in response to a control signal supplied from a scan line WS and samples a video signal supplied from a signal lien SL to a pixel capacitor Cs during a horizontal scanning period. The pixel capacitor Cs applies an input voltage Vgs to a gate G of a drive transistor Trd in response to the sampled video signal. The drive transistor Trd supplies an output current in accordance with the input voltage Vgs to a light-emitting device EL. The output current has dependency on a threshold voltage Vth of the drive transistor Trd. In order to cancel the dependency of the output current on the threshold voltage Vth, there is provided correcting means (Tr3 and Tr4) for operating in part of the horizontal scanning period, detecting the threshold voltage Vth of the drive transistor Trd, and writing the threshold voltage Vth in the pixel capacitor Cs.
