A working method of shutter glasses type 3D display, the left and right eye frame signals are alternately output to the LCD panel, driving LCD panel respectively to form left and right eye image, with the scanning backlight unit irradiation plus the shutter glasses sequential control, the left and right eye are stimulated by the left and right eye of the signal respectively, so as to feel the 3D images,in the period of the current frame signal, the working time of every block of the said backlight unit is between the moment at which the liquid crystal corresponding to every block completely react under the driving of the current frame signal and the moment at which the liquid crystal corresponding to every block begin to react under the driving of the next frame signal, the working time of every block is divided into the working time before the liquid crystal complete reacting duty1 and the working time after the liquid crystal complete reacting duty2, The luminance of every block in duty1 and duty2 is adjusted respectively, making the luminance of liquid crystal corresponding to every block in duty1 and duty2 be equal to the target luminance. The working method could reduce the ghost phenomenon caused by the crosstalk of the left and right eye frame signals; it does not need to shorten the working time of every block of BLU. |
