Problems solved by technology

The advantage of the shutter display technology is that the resolution of the display device will not be halved, but at least twice the picture update frequency of 120 Hz (Hertz, Hz) is required. However, increasing the picture update frequency will make it difficult for the liquid crystal to transition to the desired state , and the brightness of the display screen is greatly reduced
In addition, increasing the frequency of picture updates will also make the viewer's vision more likely to feel tired

Embodiment Construction

[0015] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] see Figure 3A-Figure 3B , is a schematic diagram showing the cholesteric liquid crystal display device 30 and its 3D image display principle according to the first embodiment of the present invention. The cholesteric liquid crystal display device 30 includes a substrate 300 , a light absorbing layer 302 and a cholesteric liquid crystal layer 304 . The cholesteric liquid crystal display device 30 may be an active matrix driven display device or a passive matrix driven display device. The substrate 300 can be a glass substrate or a plastic substrate. The light absorbing layer 302 can be made of black material or other materials capable of absorbing light. The light absorbing layer 302 is disposed on the substrate 300 . The cholesteric liquid crystal layer 304 is disposed on the light absorbing layer 302 , and includes a plurality o...

Abstract

The invention relates to a cholesterol liquid crystal display device, comprising a substrate, a light absorption layer and a cholesterol liquid crystal layer. The light absorption layer is arranged on the substrate. The cholesterol liquid crystal layer is arranged above the light absorption layer and comprises a plurality of lines of levorotatory cholesterol liquid crystals and a plurality of lines of dextrorotatory cholesterol liquid crystals which are alternately arranged. The cholesterol liquid crystal display device in the invention respectively reflects a levorotatory light and a dextrorotatory light by virtue of the levorotatory cholesterol liquid crystals and the dextrorotatory cholesterol liquid crystals, thus an observer can see different images with the eyes so as to form 3D development effect.

Description

technical field [0001] The present invention relates to a liquid crystal display device, in particular to a cholesteric liquid crystal display device capable of displaying stereoscopic (3D) images. Background technique [0002] The 3D display device uses spatial multiplexed or time multiplexed to allow the left eye and right eye to receive two images from different angles, and then the brain re-integrates the two images from different angles into an image with stereoscopic depth perception, forming a so-called 3D image. [0003] At present, the 3D display device still needs to wear special glasses to watch to form 3D images as the mainstream method, and this method can be further subdivided into two technologies: pattern retarder and shutter glasses. [0004] see figure 1 , is a schematic diagram illustrating the polarized 3D display device 10 . The polarizing 3D display device 10 uses spatial multitasking to allow the left eye 100 and the right eye 102 to receive differe...
