Problems solved by technology

[0013] Existing stereoscopic display pictures need to wear special stereoscopic glasses to realize, but wearing stereoscopic glasses will make the viewer feel inconvenient on the one hand; (binocular display) and convergence (convergence), resulting in differences from other depth cues such as adaptation and motion parallax
This difference will cause fatigue and dizziness to the human body, making it inconvenient to watch for a long time, and it is not conducive to some people, such as the elderly and children watching

Embodiment 1

[0138] Take 24-inch LCD monitor as an example

[0139] As shown in Figure 1, it is a structural schematic diagram of a naked-eye visible stereoscopic display system, a naked-eye visible stereoscopic display system, including a display 1 and a convex grating sheet 2, and is characterized in that a convex grating sheet 2 is arranged on the surface of the display 1 .

[0140] As shown in Figures 2 and 3, it is a schematic diagram of the structure of the convex grating sheet 2. One side of the surface of the convex grating sheet 2 is a group of corduroy-like gratings 3, and the inclination direction of the gratings 3 is inclined from upper right to lower left. The inclination angle β to the horizontal line is 71.55°, the pitch a of two adjacent gratings 3 is 0.81 mm, the thickness of the convex grating sheet 2 is 0.4 cm, the magnification of the convex grating sheet 2 is 750 times, and the grating sheet 2 can be front-facing Facing the monitor 1 screen.

Abstract

The invention relates to a display system which image in the sight of bare eye is tridimensional. This invention includes a display. It is characterized in that it has a prominentia raster slice on the surface of the invention. This invention uses a set of oblique arranged prominentia lens array, through the refraction in horizontal direction, offers different perspective image to each eye. In this way, it can present clear tridimensional image, wipe off 70% Moore veins and angle of sight can be enlarged to 120degree,besides, the resolution factor in the direction of X and Y is quite equal. Excellence of this invention are that it can make people looking at three-dimension images without glasses and definition of images can be at least 1000 as well as extensive angle of view, many clear spots, stable brightness, and so on.
