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.
