Three-dimensional display device

Abstract

The invention discloses a three-dimensional display device which comprises a display appliance, a pair of three-dimensional glasses, a liquid crystal box and a drive control circuit, wherein the display appliance is used for displaying images, and provided with a polaroid with a polarization degree of a first angle; a left lens of the three-dimensional glasses has a polarization degree of the first angle, and a right lens of the three-dimensional glasses has a polarization degree of a second angle; the liquid crystal box is provided with a plurality of independent liquid crystal units and arranged on the polaroid, one surface (adjacent to the polaroid) of the liquid crystal box has an orientation angle of the first angle, and one surface (back to the display appliance) of the liquid crystal box has an orientation angle of the second angle; the drive control circuit is connected with the display appliance and used for controlling the independent liquid crystal units, namely, synchronously controlling the distortion angles of the independent liquid crystal units according to frame signals and line signals of the display appliance, so that the polarization angle of light passing through the liquid crystal units is switched between the orientation angle of the first angle and the orientation angle of the second angle; and the two lenses of the three-dimensional glasses have the polarization degrees of the first angle and the second angle, so that human eyes can not see a picture updating process, thereby eliminating ghosting and vertigo feelings.

Description

technical field [0001] The invention relates to a display device, in particular to a stereoscopic display device. Background technique [0002] Usually, the stereoscopic image is formed according to the principle of stereo vision (stereo eyesight) through the eyes of the human body, that is, due to the existence of binocular parallax at a distance of about 65mm between the eyes, the eyes see different images through the left and right lenses, which can make people get Very real 3D feeling. In other words, the eyes see two different two-dimensional (2D) images transmitted to the human brain through the retina, and the human brain combines the two images to generate the depth and solidity of the real image. [0003] Existing 3D display devices are very complicated to realize the stereoscopic effect, and there are problems such as high system resource occupation, such as a computer display card, which alternately displays the left and right lens images through the display scre...

In this case, half of the time is when both lenses are closed, that is, only one frame of every two frames can be received by the human eye. For example, the display screen updated at a frame rate of 60HZ can only be seen by the human eye. The content of 30 frames will make the viewing feel flickering, so the frame rate needs to be doubled to eliminate the flickering feeling for the human eye. A higher frame rate also puts forward higher requirements for the display device, and the LCD worn Switching glasses also requires frame synchronization circuits and batteries, which increases weight and volume and reduces wearing comfort
