Title:
LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/108165
Kind Code:
A1
Abstract:
It is possible to provide a liquid crystal display device capable of improving response
speed as compared to the prior art. When a level of applied data signal voltage
in one of the pixels of the liquid crystal display device is changed from a previous
frame period, simultaneously with it, the luminance of the backlight device
is temporarily increased or decreased. Thus, the light quantity of light passing
through the liquid crystal layer per unit time is substantially constant before
and after the transmittance of the liquid crystal layer reaches a set value and
the apparent luminance on the display screen reaches the set value in a short time
as compared in the prior art. This improves the response speed. The liquid crystal
display device of the present invention can be applied to a mobile telephone, a
television, and a display device of a computer.
