Liquid crystal display system of double signal modes and driving method thereof

Abstract

The invention relates to a liquid crystal display system of double signal modes and a driving method thereof. The liquid crystal display system comprises a display unit, a data control unit and a scanning control unit, wherein the display unit comprises a plurality of scanning lines; the data control unit is coupled to the display unit and outputs picture signals to the display unit; the scanningcontrol unit is provided with a plurality of scanning ends, and the plurality of scanning lines are coupled at the plurality of scanning ends through a plurality of first switches and a plurality of second switches respectively; when the data control unit outputs the picture signals of a first frame, the plurality of first switches are switched on, and left eye signals in the picture signals are input into the display unit; and when the data control unit outputs the picture signals of a second frame, the plurality of second switches are switched on, and right eye signals in the picture signals are input into the display unit. The liquid crystal display system can be applied to the polarized and shutter type picture signals; and two classes of picture signals can be used in one liquid crystal display system, and the three-dimensional effect can be accurately displayed.

Description

technical field [0001] The invention relates to a dual-signal mode liquid crystal display system and its driving method, in particular to a liquid crystal display system and its driving method capable of sharing polarizing glasses-type stereoscopic picture signals and shutter glasses-type stereoscopic picture signals. Background technique [0002] In terms of the development of display technology, in addition to the pursuit of thinness and shortness, it is also hoped to achieve the goal of displaying stereoscopic images. At present, the stereoscopic display technology can be roughly divided into two ways that users need to wear specially designed glasses or watch directly with naked eyes. The glasses-type stereoscopic display technology includes shutter glasses-type stereoscopic display technology and polarized glasses-type stereoscopic display technology. Among them, the shutter glasses-type stereoscopic display is to distinguish the left and right eye signals in units of ...

AI Technical Summary

Problems solved by technology

[0003] Although the above two stereoscopic display technologies are mature, there is a problem that the image signals of the two systems cannot be shared due to the difference in the arrangement of left and right eye signals between the stereoscopic display of the polarized glasses type and the stereoscopic display of the shutter glasses type. The shutter glasses-type display system must correspond to the shutter glasses-type stereoscopic image signal (frame-frame interlaced type), and the polarized glasses-type display system must correspond to the polarized glasses-type stereoscopic image signal (line-to-line interlaced type). For one display system, multiple This picture signal has become a major problem for technicians
