Display apparatus that controls luminance irregularity and gradation irregularity, and method for controlling said display apparatus

摘要

In an active matrix display apparatus, the drive transistor to drive an OLED self-corrects the operation timing of the drive transistor. A correction transistor controls on and off of the self-correction. The drive circuit self-corrects the operation of the drive transistor by generating a luminance signal which is corrected based on a predetermined signal delivered temporarily and an operation threshold value. The current flowing to the OLED is controlled by gradually changing the voltage of luminance signal from a ramp signal line. After the luminance signal for one frame is inputted to each pixel, the same luminance signal for one frame is inputted to the each pixel in a reversed scanning direction. One frame period is divided into a plurality of subframe periods and the data control circuit inputs respectively the same luminance signal to each pixel in the plurality of subframe periods.
