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 is used for replacing a backlight part in a traditional mode to be arranged below a liquid crystal display panel, and the whole three-dimensional display device can become light and thin. Under a three-dimensional display mode, light-emitting regions and black regions are formed in the electroluminescent display panel, and thus a special-shaped grating structure is formed, wherein the light-emitting regions and the black regions are arranged alternately in the row direction and the column direction. The electroluminescent display panel provides backlight and also achieves the effect of a rear three-dimensional grating in a compatible mode, the three-dimensional grating additionally arranged in front of the liquid crystal display panel is omitted, and thus the integral light and thin design of the three-dimensional display device is facilitated. Under the three-dimensional display mode, first subpixels corresponding to the same light-emitting region are controlled to display different kinds of gray scale information, and the left eye and the right eye of a person can receive images with different kinds of gray scale information when located at two points of sight respectively, so that stereoscopic vision is generated, and 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 naked-eye 3D display devices all need to add an additional 3D grating in front of the display panel that can realize the parallax barrier, which is not conducive to the thinning and thinning of the 3D display device.
