LIQUID CRYSTAL DISPLAY DEVICE, LIQUID CRYSTAL DISPLAY METHOD, AND TV RECEIVER
Document Type and Number:
WIPO Patent Application WO/2008/015830
Kind Code:
A1
Abstract:
Provided is a liquid crystal display device comprising a display controller
(400) for outputting images independently to a first panel and a second panel
so that the images displayed on the individual panels may be superposed to one
image corresponding to an image source. The display controller (400) includes
a brightness ratio adjusting unit (402) for adjusting the gradations of images
to be outputted to individual liquid crystal panels, when the gradations of the
images to be outputted to the individual panels are synthesized to attain one
synthesized gradation, so that the display responding time period at the gradation
synthesizing time may be shorter than a preset reference display responding
time period. As a result, the contrast and the moving image performance are improved
to realize the liquid crystal display device, which is high for the display quality
not only in the still image display but also in the moving image display.
