Working method of shutter glasses type 3D (three dimensional) display

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of 3D display, in particular to a working method of a shutter glasses type 3D display. Background technique [0002] At present, most glasses-type 3D display technologies use the left and right eye frame signals to be alternately output to the LCD panel, driving the LCD panel to form left and right eye images respectively, combined with the illumination of the scanning BLU (scanning backlight unit) and shutter glasses (shutter glass) timing control, so that the left and right eye signals stimulate the left and right eyes respectively, so that people feel 3D images. Because the response speed of the LCD screen is too slow, it is necessary to adjust the timing and duty (working) time of turning on the BLU (backlight unit) and opening of the shutter glasses to reduce the influence of crosstalk between the left and right eye signals. However, due to timing control, the opening time of the backlight and the shut...

Problems solved by technology

Additionally, if figure 1 As shown, the opening time of the shutter glasses for the left eye is relatively early, and the blocks S2, S3, S4, and S5 are working to give signals to the left eye. At the same time, due to the slow response of the liquid crystal, the blocks S2, S3, S4, and S5 will exist at the same time when they are working. Influenced by the previous right-eye image to varying degrees, there will also be afterimage interference
