IMAGE DISPLAY DEVICE AND DRIVING METHOD THEREOF

摘要

An image display device in which V_th shift amount of a drive element is uniformed for each pixel. A light emitting element (D1) which emits a light by supplying a power, a drive element (Q1) which is connected to the light emitting element (D1) to control light emission of the light emitting element (D1), and a controller (U1) which detects a threshold voltage of the drive element (Q1) and controls a voltage applied to the drive element (Q1) based on the detected threshold voltage are provided. The controller (U1) applies a reverse-bias voltage or a forward-bias voltage to the drive element (Q1) when the light emitting element (D1) does not emit a light based on the comparison result between the threshold voltage and a predetermined threshold value.
