Embodiment example 1

[0046] Implementation case 1, autostereoscopic display with high brightness and large viewing angle.

[0047] Prepare a 47-inch LCD TV with a resolution of 1920*1080 and a refresh rate of 120Hz. The pixel pitch of the LCD TV is 0.5415mm. The effective area of ​​the switchable lenticular lens grating is 1040*585mm, and the inclination angle of the grating lines and the vertical direction is 18.43 degrees. It is composed of a lenticular lens grating (16) and a field type LCD screen, and line-shaped electrodes are printed on the IPO (18) glass , the conversion of the light-transmitting slit (21) and the light-shielding strip (20) is controlled by voltage to form the turn-on and turn-off of the cylinder lens. The convex surface of the lenticular grating (16) faces the LCD TV screen inwardly, and the pixel surface is in the focus position. By sharing the outer layer polarizer of the LCD TV, the polarizer (17) close to the lenticular grating (16) can be omitted. The pitch of the le...

Embodiment example 2

[0050] Implementation case two, full-resolution autostereoscopic display.

[0051] Prepare a 47-inch LCD TV with a resolution of 1920*1080 and a refresh rate of 240Hz. The pixel pitch of the LCD TV is 0.5415mm. The effective area of ​​the switchable slit grating is 1040*585mm, the inclination angle between the grating lines and the vertical direction is 18.43 degrees, the grating pitch p=0.8548mm, and the width of the light-transmitting slit (9) is 0.1710mm. The switchable slit grating is composed of a field-type liquid crystal screen, and each grid pitch is divided into 5 lines, and the corresponding line-shaped electrodes are printed on the IPO (18) glass, and the lines are controlled by voltage in two states of light transmission and light shielding At any time, only one line in a grating pitch is light-transmitting, forming the light-transmitting slit (9) of the slit grating, and other lines are light-shielding, forming the light-shielding strip (8) of the slit grating, fa...

Abstract

The invention discloses a high-resolution auto-stereoscopic display which is composed of a switching grating and a flat-panel display screen. The flat-panel display screen can be an LCD, a PDP, an LED or other equipment with a point-to-point image display function. The flat-panel display screen has high refresh frequency and can refresh an image at a frequency which is N times the base frequency under the control of a frequency-doubling player. A synchronizer controls the switching grating to carry out state switching which is synchronous with refreshing of the flat-panel display screen. Each frame of high-resolution stereoscopic synthetic image output by the frequency-doubling player is decomposed into N full-resolution sub images which are sequentially refreshed and displayed in a point-to-point manner in a basic refresh period, and the N sub images can be combined into an image with N-time definition under the action of the switching grating. The high-resolution auto-stereoscopic display has the outstanding advantage that large-viewing-angle and high-definition naked-eye stereoscopic display can be realized.

Description

Technical field: [0001] The present invention relates to a high-resolution autostereoscopic display, more specifically, to a high-definition autostereoscopic display, which can be used in stereoscopic televisions, 3D game machines, 3D advertisements, and the like. Background technique: [0002] The three-dimensional display has the characteristics of large amount of information and can reproduce all the three-dimensional information of the actual scene, so that the viewer can directly see the distance and depth of each object in the image from the display, so the viewer can obtain more comprehensive and intuitive information . Traditional stereoscopic displays require viewers to wear auxiliary tools such as polarized glasses, complementary color glasses, or liquid crystal switch glasses. Although they have a good stereoscopic effect, they are not suitable for public places, especially for displaying advertisements. [0003] In recent years, autostereoscopic technology witho...
