Abstract

The embodiment of the invention provides a display device and a driving method thereof, relates to the field of display technology and solves the problems that the process difficulty on the manufacturing of the existing liquid crystal display device is high, and the structural uniformity is not easy to control. In the embodiment of the invention, a controllable gray scale display component capable of providing a gray scale gradient backlight source, and a pixel component comprising a light path switch array are adopted, and a single light path switch can stop the light of the backlight source from passing the pixel component, so as to realize monochrome or colorful display of an image when a specific gray scale arrives, so that the structure of the display device is greatly simplified, the manufacturing process is accordingly simplified, and the problem that the structural uniformity is not easy to control is avoided, further a single pixel is driven only by controlling the on-off state of the light path switch, and the driving method of the display device is greatly simplified.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a driving method thereof. Background technique [0002] At present, liquid crystal display devices generally adopt an active matrix structure, that is, each pixel unit includes a thin film transistor, and the drain of the thin film transistor is connected to the pixel electrode of the pixel unit. When a turn-on signal is applied to the gate of the thin film transistor, the thin film transistor The transistor is turned on, so that the source and drain of the thin film transistor are turned on. The electrical signal applied to the source electrode is applied to the pixel electrode, so that the liquid crystal molecules in the pixel unit are deflected, and the light is passed or cut off. [0003] The gates of the thin film transistors of the pixel units in a row of the liquid crystal display device are connected together, and the sources of the thin fil...
