Abstract:
1. An operation method of shutter glasses based 3D (3-Dimensional) display devices, which alternatively supplies left-eye and right-eye frame signals to a liquid crystal panel to drive the liquid crystal panel to respectively form left-eye and right-eye images, which cooperate with illumination of a scanning back light unit and timing control of the shutter glasses to simulate left and right eyes respectively with left-eye and right-eye signals for perception of a 3D image, wherein in a period of a current frame signal, duty time of each of blocks of the back light unit is located between the time when liquid crystal corresponding to the block completely responds after being driven by the current frame signal and the time when the liquid crystal corresponding to the block starts to respond as being driven by a subsequent frame signal; wherein each of the blocks of the back light unit has identical duty time; and wherein for each of pixels located in the liquid crystal corresponding to each of the blocks of the back light unit, transmittance of the pixel is individually changed to T
