Embodiment Construction

[0048] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0049] see Figure 6 , which shows a stereoscopic display device according to a preferred embodiment of the present invention.

[0050] The stereoscopic display device includes a display panel 600 , a gamma voltage generator 610 , a timing controller 620 and at least one source driving circuit 630 .

[0051] The stereoscopic display device of the present invention adopts double-frame switching and is driven at a fixed frame rate. The display panel 600 is used to alternately display a left-eye image and a right-eye image and has a plurality of pixels (represented by a pixel 602 in the figure). The timing controller 620 receives a system input signal SI, and provides an image data to the source driving circuit 630 and a first set of gamma voltage V according to the system input signal SI. 11 -V 1N or a second set of gamma voltage V 21 -V ...

Abstract

The invention relates to a stereoscopic display device and a driving method thereof. The stereoscopic display device employs a double frame inversion driving mode. The stereoscopic display device comprises a display panel, a time sequence controller, a gamma voltage generator and at least one source driving circuit, wherein the display panel is provided with a plurality of pixels. The time sequence controller provides two groups of different gamma voltages for the gamma voltage generator, so the charging situations of all pixels during frame inversion tend to be accordant. By the invention, the problem of ghost phenomenon caused by insufficient charging during double frame inversion driving can be solved.

Description

technical field [0001] The present invention relates to a stereoscopic display device, in particular to a stereoscopic display device and a driving method thereof. Background technique [0002] The 3D display device forms a 3D image by alternately providing left-eye images and right-eye images, so double frame rate is required. see figure 1 , which shows the relationship between frame and polarity when a conventional stereoscopic display device is driven by 1 frame inversion. Single frame switching means that each frame switches polarity once. [0003] Frames N and N+2 display images for the left eye, and frames N+1 and N+3 display images for the right eye. In the left-eye images of frame N and frame N+2, the pixel voltage of the same pixel is the same polarity, and in the right-eye images of frame N+1 and N+3, the pixel voltage of the same pixel is also same polarity. Since the images of the same eye are all of the same polarity, mottled phenomena will occur. [0004]...
