Embodiment Construction

[0018] The slit grating of the present invention is used in a stereoscopic display device to realize the parallax effect, wherein the parallax slit grating is distributed in stripes, and the light-transmitting parts and the shielding parts are arranged alternately. The parallax barrier adopts a non-uniform period design method. Specifically, the slit grating includes several repeating periods, each repeating period includes several regions, all regions have the same grating pitch, and the edges on both sides of each region are light-shielding parts or light-transmitting parts , the distance between the light-shielding parts or the light-shielding parts of adjacent regions is less than or equal to the width of the light-transmitting parts or light-shielding parts inside the region.

[0019] However, there are different positional offsets between the regions. Preferably, the distance between the light-shielding parts or the light-transmitting parts of each adjacent region in the...

Abstract

The invention relates to slit grating and display equipment. The slit grating is used for the three-dimensional display equipment to realize a parallax effect, and comprises a plurality of repeated cycles; each repeated cycle comprises a plurality of zones; the zones have same rating pitches; shading parts or light transmission parts are formed at edges of two sides of each zone; and the gap between the shading parts or the light transmission parts of adjacent zones is smaller than or equal to the width of shading parts or the light transmission parts inside the zone. The slit grating and the display equipment can avoid moire effect and improve the three-dimensional display effect.

Description

technical field [0001] The invention relates to a stereoscopic display technology, in particular to a slit grating and a stereoscopic display device thereof. Background technique [0002] Among current display technologies, stereoscopic display technologies can be roughly divided into auto-stereoscopic for direct viewing and stereoscopic for viewing with specially designed glasses. The working principle of the glasses-free three-dimensional display technology is mainly to use a grating device to control the images received by the viewer's left and right eyes. According to the visual characteristics of human eyes, when the left and right eyes respectively watch two images with the same image content but with different parallax, the two images observed by the human eyes are synthesized into a stereoscopic image. Glasses-free stereoscopic display technology has become a development trend of 3D display technology because it is closer to people's daily habits and widely used. ...
