Example Embodiment

[0033] As described in the background art, in the existing bidirectional stereoscopic display device, the color cast is serious, which leads to cross effect, small viewing angle and poor stereoscopic image display effect. The inventor discovered through research that the reason for this problem is that in the existing bidirectional stereoscopic display device, the directions of the straight grating bars are horizontal and vertical, while the straight RGB color bars in the current display The direction of is also horizontal or vertical. Therefore, there must be a direction of grating bars and RGB color bars arranged in parallel.

[0034] At this time, such as figure 2 As shown, when the RGB color bar 20 is viewed obliquely through the grating bar 21 at position 24, the image actually seen by the left eye 22 (right eye 23) is the partial area of ​​the image that the left eye 22 (right eye 23) should see and / Or the partial area of ​​the image that the right eye 23 (left eye 22) sh...

Abstract

The invention provides a bidirectional three-dimensional display device which comprises a display screen with a plurality of parallel RGB color bars. The bidirectional three-dimensional display device further comprises a liquid crystal optical grating located on one side of the display screen, and the liquid crystal optical grating comprises a plurality of parallel vertical optical grating strips or slant optical grating strips distributed at intervals. According to the bidirectional three-dimensional display device, due to the fact that the directions of the optical grating strips in the liquid crystal optical grating are perpendicular to the directions of the RGB color bars in the display screen or preset included angles are formed between the directions of the optical grating strips in the liquid crystal optical grating and the directions of the RGB color bars and range from 0 degree to 90 degrees, the directions of the optical grating strips can not be parallel to the directions of the RGB color bars in the display screen, color shifting, the cross effect and the small view angle problem are accordingly avoided, and the display effect on a three-dimensional picture is further improved.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, and more specifically, relates to a bidirectional stereoscopic display device. Background technique [0002] At present, most naked-eye 3D (three-dimensional) display devices are equipped with a liquid crystal grating in front of a 2D (two-dimensional) display screen. During 2D display, no voltage is applied to the liquid crystal grating, which has high transmittance and basically does not affect 2D The brightness and resolution of the display screen, etc.; during 3D display, a certain voltage is applied to the electrodes of the liquid crystal grating to form black and white stripes, so that there is a gap between the images seen by the left and right eyes at the same time, and then synthesized by the brain to produce a three-dimensional effect. [0003] With the wide application of 3D display devices and people's higher and higher requirements for products, a stereoscopic ...
