Stereo display, stereo display method and backlight modulation unit thereof

Abstract

The invention provides a stereo display. The stereo display comprises a display panel, a backlight source and a backlight modulation unit, wherein the backlight modulation unit modulates light emitted by the backlight source, so that the modulated light selectively reaches a left eye view region or a right eye view region through the display panel; and the display panel selectively displays a left eye parallax image or a right eye parallax image according to the modulation state of the backlight modulation unit. The invention also provides a stereo display method and the backlight modulation unit. Through the structure and the method, the left eye parallax image and the right eye parallax image are projected to the left eye view region and the right eye view region respectively by a time division multiplexing mode by using an improved backlight system, so that the resolution and the display effect of the stereo display are improved.

Description

【Technical field】 [0001] The invention relates to stereoscopic display technology, in particular to a stereoscopic display, a stereoscopic display method and a backlight modulation unit thereof. 【Background technique】 [0002] In recent years, three-dimensional display technology has developed rapidly and has become a research hotspot. Stereoscopic display technology has important applications in medical, advertising, military, exhibition, games and other fields. Early stereoscopic display technology mainly uses stereoscopic glasses to watch stereoscopic images, while the current mainstream products are mainly naked-eye stereoscopic display devices based on binocular parallax. The main principle of the naked-eye stereoscopic display device is to install a grating in front of the display panel, and the grating provides at least two parallax images displayed on the display panel to the left eye and the right eye of the viewer respectively. Wherein, the grating may be a slit ...

AI Technical Summary

Problems solved by technology

[0003] At present, the clarity of most naked-eye stereoscopic displays based on gratings is not satisfactory

The main reasons include: first, the slit grating or cylindrical grating will form moiré fringes with the display, forming visual interference; second, the grating will divide the pixels of the display, which is fine when the display displays a large screen, but the display is small. Screens (such as text, etc.) will form cuts, so that the viewer cannot see the font clearly. Therefore, although there are many 2D / 3D switching technologies, it is particularly difficult to see small fonts clearly in a 3D state such as a game scene; Third, the gratings are distributed in front of the display, making the pixels of the display severely grainy; fourth, and most importantly, due to the limitation of the principle of stereoscopic display, most current naked-eye stereoscopic displays need to simultaneously display two or more images, resulting in a significant drop in resolution
