3d image display device and 3d image display system with uniform luminance

A 3D image display system, comprising:

• a shutter glasses with an enabling time period;
• a 3D image display device, comprising:
• a backlight source driver providing N driving current signals;
• a backlight module, electrically connected to the backlight source driver, comprising N backlight sources which emit lights when receiving N driving current signals in sequence, wherein N is a positive integral greater than 1;
• and
• a liquid crystal panel comprising a plurality of liquid crystal display zones to adjust alignment of liquid crystal molecules according to data signals;
• wherein after the first frame image is displayed in the liquid crystal panel in the first time period, when the second frame image is being displayed in the liquid crystal panel in the second time period and the shutter glasses enables, luminance of 1st˜kth backlight sources is greater than luminance of (k+1)th˜Nth backlight sources because the backlight source driver adjusts the N driving current signals, wherein N>k>1.
