Display device and drive method thereof

Abstract

The invention discloses a display device, comprising a display module and a liquid crystal light shield panel, wherein the display module is provided with a plurality of first display areas and second display areas staggered with each other, the first and the second display areas are suitable for displaying the images of left eye or right eye, the liquid crystal light shield panel is arranged at one side of the display module or in the display module, which operation mode displays a black picture normally, the liquid crystal light shield panel is provided with a plurality of first light valve areas and second light valve areas staggered with each other. The boundary of the first light valve areas and the second light valve areas will not leak light, therefore, the display device can display clear three-dimension pictures. The invention further provides another display device and a drive method.

Description

technical field [0001] The present invention relates to a display device and its driving method, and in particular to a display device capable of displaying stereoscopic images and its driving method. Background technique [0002] In terms of the development of display technology, in addition to the pursuit of thinness and shortness, it is also hoped to achieve the goal of displaying stereoscopic images. At present, the stereoscopic display technology can be roughly divided into two ways that users need to wear specially designed glasses or watch directly with naked eyes. Now, glasses-wearing stereoscopic display technology has matured and is widely used in some special purposes such as military simulation or large-scale entertainment, but the inconvenience and discomfort of wearing glasses makes this type of technology difficult to popularize. Therefore, the naked-eye stereoscopic display technology has gradually developed and become a new trend. [0003] Figure 1A and ...

Problems solved by technology

[0008] Based on the above, the mechanical grating 220 is prone to failure after a long time of rapid switching, which is the most serious and difficult to improve shortcoming of the stereoscopic image display 200

In addition, since the mechanical grating 220 will always block part of the light from the display panel 210, the stereoscopic image display 200 can only be used to display stereoscopic images, and cannot switch between the mode of displaying stereoscopic images and the mode of displaying flat images.
