Display device and driving method thereof

Abstract

The application discloses a display device and a driving method thereof, which are used for improving the light transmittance of the display device. The display device includes: an array substrate, anopposite substrate and a liquid crystal layer; the display device is divided into sub-pixel areas, and the sub-pixel areas are divided into shading areas and light-transmitting areas; each sub-pixelarea comprises an electrode structure and a first shading part, and each electrode structure comprises a first electrode, a second electrode and a third electrode; the first electrodes are divided into a first type of electrodes and a second type of electrodes; the electrode structures are configured to apply the same voltage to the first type of electrodes and the second electrodes and the thirdelectrodes, apply different voltages to the first type of electrodes and the second type of electrodes, control liquid crystal molecules to form a liquid crystal lens, so that light passing through aliquid crystal lens is converged to the first shading part; and the electrode structures are further configured in that: a voltage is not applied to the first electrodes, different voltages are applied to the second electrodes and the third electrodes, and the liquid crystal molecules are controlled to form a liquid crystal grating, so that at least part of light passing through the liquid crystalgrating is emitted from the light-transmitting areas.

Description

technical field

[0001] The present application relates to the field of display technology, in particular to a display device and a driving method thereof. Background technique

[0002] With the increasing development of display technology, various display technologies are constantly emerging, among which, transparent display technology has attracted more and more attention because of the light transmission characteristics of the display panel. Since the transparent display device has a certain light penetration, it can not only display the picture on the display screen, but also watch the background behind the display screen through the display screen, so it is more suitable for building windows, car windows, shop windows, etc. .

[0003] Liquid crystal display is a display device used on a large scale at present. It has a series of advantages such as high color gamut, lightness and thinness, and fast response time. It has mature technologies in theoretical research and pra...
