Display device and method for driving display device

摘要

A display device has a display section including pixels having light-emitting elements spontaneously emitting light depending on a current amount and pixel circuits for controlling current to be applied to the light emitting elements according to a video signal; scan lines for supplying a selection signal, which selects a pixel to be emitted, to the pixels at a predetermined scan cycle; data lines for supplying the video signal to the pixels; and transistors receiving the selection signal and driving the pixels, all of which are disposed in a matrix form. The display device comprises a gamma transformer for transforming the video signal so as to have a gamma characteristic and a transistor controller for controlling current-voltage characteristics of the transistors so as to have a linear characteristic if the gamma characteristic of the signal transformed by the gamma transformer is multiplied by the current-voltage characteristics of the transistors.
