Method For Displaying Stereoscopic Image And Corresponding Stereoscopic Image Displaying Device

A method for displaying stereoscopic image for use with a stereoscopic image displaying device, the stereoscopic image displaying device comprising a display panel, a backlight module, and shutter glasses, the display panel being divided into a plurality of display zones, the backlight module being correspondingly divided into a plurality of light source zones, wherein the method for displaying stereoscopic image comprises:

• sequentially writing image data of first polarity into the display zones;
• sequentially activating the light source zones to sequentially scan the image data of first polarity of the display zones, wherein a starting point for activating the light source zones lags behind a starting point for writing the image data of first polarity into the display zones by a half of a frame period;
• opening a left-eye shutter of the shutter glasses and shutting a right-eye shutter in order to receive the image data of first polarity as left-eye image data;
• sequentially writing image data of second polarity into the display zones, wherein the second polarity is opposite to the first polarity;
• repeating to sequentially activate the light source zones to sequentially scan the image data of second polarity of the display zones, wherein a starting point for activating the light source zones lags behind a starting point for writing the image data of second polarity into the display zones by a half of the frame period;
• and
• shutting the left-eye shutter of the shutter glasses and opening the right-eye shutter in order to receive the image data of second polarity as right-eye image data.

A stereoscopic image displaying device, wherein the stereoscopic image displaying device comprises:

• a display panel, which sequentially writes in left-eye image data and right-eye image data;
• a backlight module, which is sequentially activated and deactivated in order to scan the left-eye image data and the right-eye image data;
• and
• shutter glasses, which alternately open and shut a left-eye shutter and a right-eye shutter in order to receive the left-eye image data when the left-eye shutter opens and to receive the right-eye image data when the right-eye shutter opens;
• wherein the left-eye image data received when the left-eye shutter opens are completely image data of first polarity, and the right-eye image data received when the right-eye shutter opens are completely image data of second polarity.
