Abstract

A display device includes a scan write line for receiving a scan write signal, a first driving voltage line for receiving a first driving voltage, a first data line for receiving first data voltages, a second data line for receiving second data voltages, and a sub-pixel connected to the scan write line, the first data line, the second data line, and the first driving voltage line, wherein the sub-pixel includes a light emitting element connected to the first driving voltage line, a constant current generator configured to apply a driving current to the light emitting element according to a first data voltage among the first data voltages of the first data line, and a light emission period controller configured to control a light emission period of the light emitting element according to a second data voltage among the second data voltages of the second data line.

Description

technical field [0001] Aspects of embodiments of the present disclosure relate to display devices. Background technique [0002] With the development of information technology, demands on display devices for displaying images have increased in various forms. For example, display devices are applied to various electronic devices such as smart phones, digital cameras, notebook computers, navigators, and smart TVs. The display device may be a flat panel display device such as a liquid crystal display device, a field emission display device, or a light emitting display device. [0003] Since the light emitting display device includes a light emitting element through which each of the subpixels in the display panel emits light by itself, the light emitting display device can display images without a backlight unit providing light to the display panel. Each of the subpixels in the light emitting display device may include: a light emitting element; a driving transistor for adjus...
