Display device, driving method of the same and electronic apparatus using the same

Abstract

A display device, a driving method and an electron of this invention can correct the self-adaptivity migration rate according to the gray scale of a video signal and improve evenness of images. A writing scanner (4) comprises a shift register (S / R) and an output buffer (4B). The shift register (S / R) is synchronous with a line order scanning so as to generate input signals (IN, AZX) to each level order of the shift register. The output buffer (4B) is connected between each level an each scanning line (WS) of the shift register (S / R) and outputs a control signal to the scanning line (WS) based on input signals (IN, AZX). The shift register (S / R) changes the level of input signals (IN, AZX) in at least two stages. The output buffer (4B) changes the decline of the control signal (WS) for stopping the time of specified sampling transistor based on the level change of the input signals (IN, AZX) along the waveform, such that the changeable control to the migration rate correction period based on the signal level of the video signal.

Description

technical field [0001] The present invention relates to a display device that displays an image by current driving a light emitting element allocated to each pixel and a driving method thereof. It also relates to electronic equipment using such a display device. More specifically, it relates to a driving method of a so-called active matrix display device in which the amount of current passed to a light emitting element such as an organic EL is controlled by an insulated gate field effect transistor provided in each pixel circuit. Background technique [0002] In a display device such as a liquid crystal display, a large number of liquid crystal pixels are arranged in a matrix, and an image is displayed by controlling the transmission intensity or reflection intensity of incident light for each pixel according to pixel information to be displayed. The same is true for organic EL displays and the like in which organic EL elements are used as pixels, but unlike liquid crystal ...

Problems solved by technology

However, conventional display devices do not necessarily take into account the dependence of the optimum mobility correction time on the signal potential of the video signal, which has become a problem to be solved in order to improve the uniformity of the screen.
