Embodiment Construction

[0027] A parallax barrier that uses a slit grating to form a parallax image is one of the technologies for realizing naked-eye 3D display. The slit grating is usually composed of a plurality of parallel slits of equal width and equal intervals, and the slits are light-transmitting stripes. , between adjacent slits are light-shielding stripes. The specific principle of the parallax barrier 3D display is: the pixels of the display screen are transmitted to the observation point through the light-transmitting stripes on the parallax barrier, and the left and right eyes of the observer at the observation point can see different pixels, forming Parallax images, so that the observer's brain can synthesize a stereoscopic effect to achieve 3D display.

[0028] The parallax barrier type 3D display technology in the prior art, because the left and right eyes of the observer can only see half of the pixels, the resolution of the display screen is reduced by half, the brightness is also r...

Abstract

The invention relates to the technical field of 3D display, and discloses a parallax barrier and a display device. The parallax barrier realizes 3D display by using a slit grating, and includes a plurality of spaced and parallel first stripes, and light-transmitting stripes are formed between the first stripes, the light transmittance of the first stripes is greater than zero, and the observer can see through After passing through the parallax baffle, all pixels of the display screen can be seen by left and right eyes, which improves the resolution and brightness of 3D display and reduces energy consumption. And the light transmittance of the first stripe is set to be lower than that of the light-transmitting stripe, so that there is parallax in the images seen by the left and right eyes, so that the brain of the observer can synthesize a three-dimensional effect and realize 3D display. At the same time, the left and right eyes of the observer can see all the pixels through the parallax barrier, which overcomes the problem of the dead zone where the 3D display cannot be seen in the parallax barrier in the prior art.

Description

technical field [0001] The invention relates to the technical field of 3D display, in particular to a parallax barrier and a display device. Background technique [0002] At present, 3D display has gradually become the standard configuration in the market. Among them, naked-eye 3D display technology has become the mainstream. In the naked-eye 3D technology, there are mainly parallax barrier method, lens method, directional backlight method, etc., but considering the LCD process compatibility and cost issues, the parallax barrier method is currently a more common method. [0003] see figure 1 As shown, the parallax barrier 20' is a slit grating, including opaque stripes 21' and light-transmitting stripes 22' between the opaque stripes 21', and the light-transmitting stripes 22' correspond to the slits of the slit grating , the slits are usually set with equal width and equal intervals. Generally, the commonly used slit grating is made by carving a large number of parallel...
