Three-dimensional display device and driving method thereof

Abstract

The invention discloses a three-dimensional display device and a driving method thereof. An electroluminescent display panel which is arranged below a liquid crystal display panel for black and white display and used for colorful display is adopted to replace backlight in a traditional form and provide chrominance information of a picture, and the whole three-dimensional display device can be lightened and thinned. In a three-dimensional transverse screen or vertical screen display mode, light-emitting regions and back regions are formed in the electroluminescent display panel and are arrayed alternately in the column direction to form a special-shaped grating structure, and therefore the step of additionally arranging a three-dimensional grating before the liquid crystal display panel is omitted, which is beneficial to the overall lighting and thinning design of the three-dimensional display device. In the three-dimensional transverse screen or vertical screen display mode, all first subpixels which correspond to the same light-emitting region and are used for providing gray scale information of different view point images are controlled, the left eye and the right eye of a user receive images with different pieces of gray scale information when located at two view points respectively to generate stereoscopic vision, and bi-directional naked eye three-dimensional display at the subpixel level is achieved.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional display, in particular to a three-dimensional display device and a driving method thereof. Background technique [0002] The main principle of three-dimensional (3D) display technology is to enable the viewer's left eye and right eye to receive images with subtle differences, that is, the left view and the right view, and the two views are integrated after analysis by the brain so that the viewer perceives the objects in the picture depth, thereby creating a three-dimensional effect. [0003] Early 3D display devices required users to wear corresponding 3D glasses, and glasses-free 3D display devices have attracted much attention in recent years. There are generally two types of devices for naked-eye 3D display: a slit grating type 3D display device and a microlens array type 3D display device. The slit grating type, also known as the parallax barrier, is usually realized by us...

AI Technical Summary

Problems solved by technology

[0004] At present, the existing 3D display devices with parallax barriers generally can only be viewed in a state of horizontal screen or vertical screen, which limits the 3D viewing effect.
