Problems solved by technology

What they use is to place a panel with a small hole in front of the image display screen to isolate the left and right parts of the stereoscopic image and transmit them to the left and right eyes of the viewer in a directional way. This solution will greatly lose the resolution of the image.

Embodiment Construction

[0011] The working principle of ordinary liquid crystal display is as follows: the uniform white light emitted by the backlight module passes through the screen, the transmittance of different points on the screen is different, the color and brightness of the transmitted light are different, and the user sees different colors on the screen. Brightness images, people's left and right eyes observed exactly the same plane image, no stereoscopic.

[0012] When human beings observe a real object, there is a distance between their eyes, and the images seen by the two eyes are slightly different. The human brain automatically fuses the two images to produce a three-dimensional effect. The pseudo-3D display technology does not create a 3D object that is consistent with the real object. Instead, several images are displayed at the same time, and the left and right eyes get different images respectively by using optical methods, so that people have a three-dimensional effect.

Abstract

The invention is mainly applied to display and display screen in order to bring about a 3-D effect to the users. For the purpose of observing 3-D images without 3-D glasses, it tires to change the optical structure of an ordinary display so as to realize a simple 3-D display technique compatible 2-D plane display. This solution generates a group of line light sources by grating, polarizing plate or plastic lens, so as to realize the 3-D display. For the 2-D display, light sources are changed into multiple groups of line light sources or uniform illuminating light. It makes parallel lines on the surface of the glass plated with conductive film, and the polarizing materials are placed in between two pieces of glass, which composes a grating to cooperate with the polarizing plate so as to generate line light sources or uniform illuminating light under different voltages. And it adopts multiple side-by-side lenses to cooperate with the tubes so as to realize one or multiple groups of line light sources.

Description

technical field [0001] Monitors, display screens, and various civilian and military displays give users a sense of depth. Related to optics, materials science and other disciplines Background technique [0002] Current mainstream monitors are all flat, and three-dimensional objects are displayed on the plane, which lacks a sense of three-dimensionality. To observe the three-dimensional effect like a three-dimensional movie, stereoscopic glasses must be used. The three-dimensional display technology represented by Philips does not need to use stereo glasses, and can get a good three-dimensional effect, but can only display three-dimensional images, and cannot display two-dimensional plane images well, and loses the resolution of two-dimensional images. Taiwan Industrial Technology Research Institute adopts micro-phase difference plate technology to produce many lines on the plate with similar depth and light wavelength. This solution is suitable for projection display, but p...
