Abstract:
1. A stereoscopic image displaying system comprising: a display panel for periodically displaying a left-eye image for a user's left eye to view and a right-eye image for a user's right eye to view; a pair of shutter glasses comprising a left-piece eyeglass and a right-piece eyeglass which are periodically and alternately turned on and off for respectively receiving the left-eye image and the right-eye image; a backlight plate disposed corresponding to the display panel, the backlight plate being divided into a plurality of regional light sources from top to bottom; and a backlight controller for providing control signals to turn on the regional light sources, wherein during one image frame displaying period, time points for turning on the respective regional light sources are different from each other, and turn-on durations that the respective regional light sources are turned on are different from each other, wherein the backlight controller comprises: a microprocessor for providing an enable signal based on the turn-on durations and the time points of the respective regional light sources; and a light source driver coupled to the microprocessor, for driving the regional light sources respectively via different channels according to the enable signal, wherein driving currents which are provided by the light source driver and supplied to the regional light sources via the channels are different while an illuminated energy for every one of the regional light sources is the same in one image frame displaying period.
