Patent ID: 8462201

Claim:
A stereoscopic image displaying method, for sequentially displaying a plurality of display images, a cycle of each of the display images sequentially comprising a first time period, a first vertical blanking interval, a second time period, and a second vertical blanking interval, the stereoscopic image displaying method comprising: performing a data providing step to provide a first image data to display a first image in the first time period by scanning, to maintain the first image in the first vertical blanking interval by maintaining the first image data, to provide a second image data to display a second image in the second time period by scanning, and to maintain the second image in the second vertical blanking interval by maintaining the second image data; performing a polarization adjusting step to render the first image to have a first polarization state in the first time period and in the first vertical blanking interval, and to render the second image to have a second polarization state in the second time period and in the second vertical blanking interval; and performing a backlight controlling step to provide a first backlight mode in a period of time within the first time period which starts from a beginning of the first time period and in a period of time within the second time period which starts from a beginning of the second time period, and to provide a second backlight mode in a remaining period of time within the first time period, in the first vertical blanking interval, in a remaining period of time within the second time period, and in the second vertical blanking interval, wherein a brightness of the second backlight mode is greater than a brightness of the first backlight mode, wherein the data providing step displays the first image and the second image on a display panel, the polarization adjusting step is performed with a light modulation device, and the light modulation device is disposed in front of the display panel.
