Switching box and three-dimensional display system using same

Abstract

The invention provides a switching box and a three-dimensional display system using same. The switching box comprises an input unit, a first output unit and a processing unit. The input unit is used for receiving a video signal from a set top box and transmitting the video signal to the processing unit, and the processing unit is used for processing the video signal into a left-eye picture frame and a right-eye picture frame, and for outputting the left-eye picture frame and the right-eye picture frame to a television through the first output unit frame by frame. According to the mode, the switching box is connected between the set top box and the television, and the switching box is used for processing the video signal into the left-eye picture frame and the right-eye picture frame and outputting the video signal into the left-eye picture frame and the right-eye picture frame to the television frame by frame, so that after the three-dimensional display system is used, the generation of color distortion and dinginess can be avoided, the generation of color cast and double image can be reduced, a three-dimensional display effect can be improved, and user experience can be improved.

Description

technical field [0001] The invention relates to the field of stereoscopic display, in particular to a conversion box for realizing the function of stereoscopic display and a stereoscopic display system using the conversion box. Background technique [0002] Stereoscopic TV has developed rapidly, and CCTV's stereoscopic channel began trial broadcast on New Year's Day in 2012. Currently, stereoscopic display technologies used in stereoscopic televisions include shutter-type stereoscopic display technologies and polarization-type stereoscopic display technologies. [0003] The stereoscopic television in the prior art includes: a red-blue stereoscopic display conversion box, a television, and red-blue glasses. Wherein, the stereoscopic TV processes the video signal through the red-blue stereoscopic display conversion box, so that the red-blue misplaced display screen of the TV is displayed. Red-blue glasses include a left-eye lens and a right-eye lens. The left-eye lens is a r...

Problems solved by technology

Because the red and blue glasses are filtered through the left and right glasses, the colorful display screen will produce color distortion and dimness.

In addition, the white balance of each TV will deviate, resulting in a color cast in the TV display screen. If the filter effect of the red and blue glasses does not reach the preset effect, the filter is not clean, resulting in color cast and color cast in the stereoscopic TV. ghosting effect
