Problems solved by technology

The slit grating stereoscopic display has good stereoscopic display characteristics, but because the left and right eye disparity maps are displayed alternately on the same display screen, it has an inherent defect: the resolution is at most half of the corresponding 2D display
This is extremely unfavorable for today's pursuit of high-resolution display trends, and urgently needs to be improved.

Embodiment Construction

[0015] An embodiment of a full-resolution 3D autostereoscopic display device based on a polarizing parallax bar screen proposed by the present invention will be described in detail below to further describe the present invention in detail. It is necessary to point out that the following examples are only used for further description of the present invention, and cannot be interpreted as limiting the protection scope of the present invention, and those skilled in the art make some non-essential improvements to the present invention according to the above-mentioned content of the present invention And adjustments still belong to the protection scope of the present invention.

[0016] According to the present invention, a 2.2-inch 3D autostereoscopic display screen is produced. A 2.2-inch 176×220 resolution TFT (field thin-film transistor) liquid crystal display is used to display the left and right eye parallax images at a frequency of 120Hz. The polarization switch screen adopt...

Abstract

This invention discloses one whole resolution 3D free space display device and its method based on bias vision difference grating screen, wherein, the device comprises plane display screen, bias switch screen and bias vision difference grating screen; the bias grating screen comprises part semi-wave screen, infraction screen and bias grating screen; the infraction screen has infraction property in vertical direction and the bias grating screen is formed by two bias vertical slices; the plane display screen is to display one semi-wave resolution pattern in open status and other half vision pattern in close status.

Description

1. Technical field [0001] The present invention relates to the technical field of three-dimensional (3D) stereoscopic display, and more specifically, the present invention relates to the technical field of 3D autostereoscopic display with naked eyes. 2. Background technology [0002] Realizing 3D display is a long-term dream of mankind. With the development of 3D naked-eye autostereoscopic display technology, this dream is gradually being realized. Wherein the slit grating type stereoscopic display based on binocular parallax and grating light splitting principle is an important naked-eye 3D autostereoscopic display, which is formed by adding a slit grating on a two-dimensional (2D) flat display. 2D flat panel displays include conventional liquid crystal display LCD, plasma display PDP, field emission display FED, organic electroluminescent display OLED, etc. The slit grating stereoscopic display has good stereoscopic display characteristics, but because the left and right...
