AI Technical Summary

Problems solved by technology

Therefore, when the total luminance (current value) of pixels in each row is different in each row, even when the signal voltage of the same gray scale is applied, the actual light emission luminance of each row will be different (horizontal crosstalk). Therefore, there is a problem that image quality degradation occurs

Abstract

There is provided a display device capable of reducing a horizontal crosstalk. the display device includes: a plurality of light emitting elements two-dimensionally arranged in a horizontal direction and a vertical direction, and including an anode electrode, a light emitting layer, and a cathode electrode; and a voltage generating circuit applying a correction voltage corresponding to a video signal of one horizontal line to the cathode electrode.

Description

technical field [0001] The present invention relates to a display device including a light emitting element. Background technique [0002] In recent years, in the field of display devices for displaying images, a display device that utilizes an element such as an organic EL (Electroluminescence) element whose luminance depends on a flow has been developed and gradually commercialized. The current-driven optical element that changes the current value is used as the light-emitting element of the pixel. Unlike liquid crystal elements and the like, this organic EL element is a self-luminous element. Therefore, a display device using an organic EL element (organic EL display device) does not require a light source (backlight), so that the display device can be made thinner and brighter than a liquid crystal display device that requires a light source. Specifically, in the case of employing the active matrix method as a driving method, each pixel can be turned on and kept, and l...
