Abstract

The invention discloses a display device. The display device comprises a three-dimensional display module, a transparent display module and a liquid crystal light valve, wherein the transparent display module is overlaid on the upper portion of the liquid crystal light valve, the three-dimensional transparent module is overlaid on the upper portion of the transparent display module, and the three-dimensional display module, the transparent display module and the liquid crystal light valve all comprise multiple electrodes which can be controlled independently. When display contents are arranged on the transparent display module, an area on the three-dimensional display module is in a three-dimensional (3D) display state, wherein the area on the three-dimensional display module corresponds to the display contents on the transparent display module, the other areas of the three-dimensional display module are in a two-dimensional (2D) display state. An area on the liquid crystal light valve is in a light-proof state, wherein the area on the liquid crystal light valve corresponds to the display contents on the transparent display module, and the other areas of the liquid crystal light valve is in a transparent state or a semi-transparent state. The display device is not only capable of improving real effects of 3D frames displayed by the 3D display area on the display device, but also improving a contrast ratio between stereo display and transparent display.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] With the rapid development of display technology, people can no longer be satisfied with two-dimensional (Two Dimension, 2D) display images, but need a three-dimensional (Three Dimension, 3D) stereoscopic display device to provide a sense of depth and more comprehensive Information. After more than ten years of development, 3D display technology has achieved very fruitful results. There have been devices capable of 3D imaging such as handheld observers, 3D stereoscopic glasses, and helmet displays. Up to now, the latest ones that do not need glasses Glasses-free 3D display using technical solutions such as prisms, lenses, gratings, and electronic switches. [0003] At the same time, research on transparent display devices is also being actively carried out. In addition to realizing image display thereon, this transparent ...
