Problems solved by technology

The threshold voltage of the drive transistor V th Or in the case where the mobility μ varies depending on the pixel circuit, the value of the current flowing through the driving transistor varies depending on the pixel circuit, so even if the same voltage is applied to the gate of the driving transistor in the pixel circuit, the luminance of light emission Also varies with the organic EL element, which impairs the uniformity of the screen

Abstract

The invention discloses a display and a method of driving the same. The display includes: a pixel circuit array section including a plurality of light-emitting elements and a plurality of pixel circuits; a scanning line drive circuit sequentially selecting the plurality of light-emitting elements and the plurality of the pixel circuits; a signal line drive circuit writing a light emission potential corresponding to a signal potential to a selected pixel circuit; and a control circuit, in which in each frame period, the control circuit outputs a light-off control signal at a lapse of a first period after writing the light emission potential to the selected pixel circuit by the signal line drive circuit, and then the control circuit outputs a light-on control signal at a lapse of a second period, and after that, the control circuit outputs a light-off control signal at a lapse of a third period which is longer than the first period.

Description

technical field [0001] The present invention relates to a display device including a light emitting element and a method of driving the display device. Background technique [0002] In recent years, in the field of display devices that display images, display devices using current-driven optical elements such as organic EL (Electroluminescence) elements as light-emitting elements of pixels have been developed for commercialization. , the light emission luminance of the current-driven optical element changes according to the value of the current flowing therethrough. Unlike liquid crystal elements and the like, organic EL elements are self-luminous elements. Therefore, in a display device (organic EL display device) using an organic EL element, a light source (backlight) is not required, and therefore, the profile of the display device can be reduced and the brightness of the display device can be increased compared with a liquid crystal display device that requires a light ...
