ILLUMINATING DEVICE, BACKLIGHT DEVICE, LIQUID CRYSTAL DISPLAY DEVICE, METHOD FOR CONTROLLING ILLUMINATING DEVICE AND METHOD FOR CONTROLLING LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/029548
Kind Code:
A1
Abstract:
An illuminating device is provided with a plurality of light source modules (LM)
each of which has a light emitting body and a driving circuit for driving the light
emitting body, and the illuminating device separately controls the driving
circuit of each light source module. All the light source modules are grouped
by having a plurality of light source modules arranged at an interval (d) as one
group. A step of lighting light emitting bodies of the light source modules belonging
to the same group (for instance, LM(1, 1)·LM(1, 9)) at the same time under
prescribed conditions is performed in sequence for all the groups. Based on
the obtained light emitting quantity of the light emitting body of each light
source module (LM), the driving circuit of the light source module is controlled.
Thus, in a backlight device provided with a plurality of illuminating areas,
the light emitting quantity in each illuminating area can be accurately corrected
in a short time.
