Embodiment Construction

[0023] Figure 5 A schematic diagram showing the stereoscopic image display system of the present invention. Such as Figure 5 As shown, the stereoscopic image display system 10 of the present invention includes a display panel 11 (such as a liquid crystal display panel) in the display device and shutter glasses 17 (such as liquid crystal shutter glasses) for viewing images displayed on the display panel 11 . In the present invention, the display panel 11 periodically displays the left-eye image for the user's left eye and the right-eye image for the user's right eye in a time division (time division) manner. The image display of the display panel 11 of the present invention The frequency is at least greater than 120 Hz, which is more than twice the image display frequency of a conventional display panel. The shutter glasses 17 have a left lens 171 and a right lens 172 , and the left lens 171 and the right lens 172 exhibit periodic alternate switching operations. In a speci...

Abstract

The invention provides a stereo image display system and method. The system comprises a display panel, a backlight plate, a backlight controller and a pair of shutter glasses, wherein the display panel is used for periodically displaying a left-eye image and a right-eye image; the backlight plate is corresponding to the display panel, and the backlight plate is divided into a plurality of area light sources from top to bottom; the backlight controller provides a control signal to open the area light sources; in the display period of a frame of image, the opening time points of the area light sources are different, and the opening time lengths of the area light sources are different; and the shutter glasses comprise a left lens and a right lens which are periodically opened and closed, and the left lens and the right lens are respectively used for receiving the left-eye image and the right-eye image. The stereo image display system can promote the brightness expression of the liquid crystal display panel in the stereo image display process, and meanwhile the occurrence probability of a ghost phenomenon or an overlapping phenomenon is minimized.

Description

technical field [0001] The present invention relates to a stereoscopic image display system and method, in particular to a stereoscopic image display system and method for controlling the turn-on time of the backlight. Background technique [0002] In the current stereoscopic image display system, one is that the liquid crystal display panel alternately displays the left-eye image and the right-eye image in a time-division manner. The user wears shutter glasses to receive the left-eye image with the left eye, and the right eye to receive the right-eye image to achieve stereoscopic vision. image perception. Such a stereoscopic image display system needs to increase the frame rate to 120 Hz and increase the vertical blanking interval (VBI) to provide time for human eyes to receive the image. [0003] figure 1 A schematic diagram showing a scan sequence and a backlight turn-on sequence in a known liquid crystal display panel. figure 2 A schematic diagram showing an image wr...
