Three-dimensional display module capable of being viewed in two directions and LCD panel

Abstract

The invention discloses a three-dimensional display module capable of being viewed in two directions, comprising an LCD (Liquid Crystal Display) screen and a grating display screen. The LCD screen provides backlight of a light source; the grating display screen is attached to the LCD screen and is provided with a transversal grating fringe and a vertical grating fringe with controllable display states; the transversal grating fringe transversally blocks the pixels of the LCD screen, and the vertical grating fringe vertically blocks the sub-pixels of the LCD screen. The vertical grating fringe of the grating display screen can vertically block the sub-pixels of the LCD screen so as to overcome the pixel arrangement limit of the prior LCD and freely realize the three-dimensional viewing effect in the transversal direction and the vertical direction without color change phenomena while improving the display resolution and viewing clearer and more refined three-dimensional images.

Description

technical field [0001] The invention relates to the field of liquid crystal display, and more specifically relates to a stereoscopic display module and a liquid crystal display panel capable of bidirectional viewing. Background technique [0002] According to research, when our human eyes observe a three-dimensional object, because the two eyes are horizontally separated at two different positions, the images of the observed object are different, and there is an aberration between them. Due to this aberration Through the existence of the human brain, we can feel the depth and stereoscopic changes of a three-dimensional world, which is the so-called principle of stereo vision. According to the principle of stereo vision, if we can allow our left and right eyes to see two images taken at different positions, we can experience a three-dimensional three-dimensional space from these two images. According to this principle, the existing technology enables the flat panel display t...

Problems solved by technology

[0003] However, due to the influence of the liquid crystal display (Liquid Crystal Display, LCD) pixel arrangement (please refer to figure 2 ), at the same time, in order to be able to block a complete pixel, to prevent the user from seeing only one or two sub-pixels in R, G, and B due to changes in the relative positions of the human eye and the display screen when viewing 3D images, so that the phenomenon of color transformation occurs, When the above method is implemented, the slit direction of the strip grating can only be pasted perpendicular to the sub-pixel direction, so the 3D display in the prior art can only meet the needs of viewing from a single direction
