IMAGE DISPLAY DEVICE AND DRIVING METHOD OF THE SAME

An image display device equalizes an amount of shift in Vth of a driving element for each pixel. Provided are a light-emitting element (D1) that emits light corresponding to current flowing therethrough; a driving element (Q1) that is connected to the light-emitting element (D1) and controls light e...

Summary:An image display device equalizes an amount of shift in Vth of a driving element for each pixel. Provided are a light-emitting element (D1) that emits light corresponding to current flowing therethrough; a driving element (Q1) that is connected to the light-emitting element (D1) and controls light emission of the light-emitting element (D1); and a controller (U1) that detects a threshold voltage of the driving element (D1) and controls an applied voltage to the driving element (D1) based on the detected threshold voltage. The controller (U1) applies voltages for a reverse or forward bias to the driving element (D1) based on a comparison result between the threshold voltage and a predetermined threshold when the light-emitting element (D1) does not emit light.
