The sampling transistor samples a video signal in the holding capacitor, the driving transistor changes the device to a luminous state, the switching transistor becomes ON in advance of the sampling of the video signal to change the light emitting device to a non-luminous state, and the sampling transistor takes in the OFF voltage from the signal line to the driving transistor, thereby preventing a penetration current from flowing from the power source toward the fixed potential.

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.
