AI Technical Summary

Benefits of technology

The present technology allows creation of special displays where different images are displayed separately without interference between them or any changes made during playback due to slight movements caused by external factors like vibrations. This helps improve viewers' experience when watching 3D movies through stereoscopy techniques.

Problems solved by technology

In this patented technology described in the technical problem addressed in the patents describes how current methods used to switch between different types of images displayed simultanously cause interference or even distortion effects due to overlapping areas caused by multiple horizontal sync signals received through separate shutters attached at one end to each screen's frame.

Embodiment Construction

[0047]Referring to FIGS. 4 to 6, the preferred embodiment of an active shutter stereoscopic image display system according to the present invention comprises a stereoscopic image display device 21 and shutter glasses 22. In this embodiment, the stereoscopic image display device 21 is a raster scan type TV, and the shutter glasses 22 are liquid crystal shutter glasses.

[0048]The stereoscopic image display device 21 includes a display processor 211, a display screen 212, a signal generator 213, a delay module 214, and a signal transmitter 215.

[0049]Further referring to FIGS. 7 and 8, the display processor 211 is for receiving a video input signal and outputting a video output signal sequence according to a frame sync signal (e.g., vertical sync signal) acquired from the video input signal. The display screen 212 is electrically connected to the display processor 211 for receiving the video output signal sequence. The video output signal sequence corresponds to a sequence of left-eye and r

Abstract

A stereoscopic image display device is for use with shutter glasses having left and right shutter lenses and includes a display processor, a display screen, a signal generator, and a signal transmitter. The display processor is for receiving a video input signal and outputting a video output signal sequence according to a frame sync signal acquired from the video input signal. The display screen is for receiving the video output signal sequence corresponding to a sequence of left-eye and right-eye images and displays the left-eye and right-eye images in an alternating manner according to the frame sync signal. The signal generator is for generating a shutter sync control signal that is transmitted to the shutter glasses by the signal transmitter for controlling duty cycles of alternating operations of the shutter glasses according to the frame sync signal.
