Sight distance optimizing structure and method of display driving chip for controlling three-dimensional display screen

Abstract

The invention discloses a sight distance optimizing structure of a display driving chip for controlling a three-dimensional display screen. The sight distance optimizing structure is mainly composed of a control unit and a display unit, wherein the control unit comprises a display control and a sight distance control, the display unit comprises a liquid crystal display and a liquid crystal optical grating and is electrically connected with the control unit through an FPC, the sight distance control and the display control are arranged in a side-by-side mode and communicated with the display unit, and the sight distance control comprises a distance sensor and a distance control circuit. One end of the distance control circuit is electrically connected with the distance sensor, and the other end of the distance control circuit is electrically communicated with the liquid crystal optical grating. According to the combined design of the structure, the sight distance optimizing structure of the display driving chip for controlling the three-dimensional display screen is achieved, and therefore the good effects of automatically conducting sensing, optimizing and control over the sight distance and expanding the sight distance range are achieved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional images, in particular to a viewing distance optimization structure and method for a display driver chip to control a three-dimensional display screen. Background technique [0002] Today, three-dimensional display imaging technology and equipment are developing rapidly, among which: the parallax barrier method is a kind of naked-eye 3D. out of the grating, so that the sub-pixels of the odd (even) columns of the display can only enter the left eye of the person, and the sub-pixels of the even (odd) columns can only enter the right eye of the person. In this way, the images captured by the left and right eyes of the observer A slight deviation occurs, and finally read as a three-dimensional image through the retina to produce a three-dimensional effect. [0003] The grating includes a liquid crystal grating, which is developed to replace the traditional shading plate technology. However, ...

AI Technical Summary

Problems solved by technology

[0003] The grating includes a liquid crystal grating, which is developed to replace the traditional shading plate technology. However, the distance from the ordinary liquid crystal grating to the LCD screen is fixed, and the transparent and opaque parts of the liquid crystal grating are also of equal width, so the viewing distance is strictly limited. The range requirement, that is to say, the correct 3D picture cannot be seen outside the line-of-sight range
