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 baffle and a display device. According to the parallax baffle, the 3D display is achieved through slit grating, the parallax baffle comprises multiple first fringes which are arranged in parallel and at intervals, transmitting fringes are formed among the first fringes, the light transmittance of the first fringes is larger than zero, all the pixels of a display screen can be seen by an observer with both eyes through the parallax baffle, the distinguishability and luminance of the 3D display are improved, and the energy consumption is reduced. The light transmittance of the first fringes is set to be less than that of the transmitting fringes, parallax is formed between an image seen by the left eye and an image seen by the right eye, so that a three-dimensional effect can be composited by the brain of the observer, and the 3D display is achieved. Meanwhile, all the pixels can be seen by the observer with both eyes through the parallax baffle, and the problems that in the prior art, a dead zone exists in a parallax baffle and the 3D display can not be seen in the dead zone are overcome.

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...
