LIQUID CRYSTAL DISPLAY APPARATUS AND ILLUMINATING APPARATUS THEREFOR
摘要:
An LCD apparatus includes an LCD panel to display an image and an LED backlight to illuminate the LCD panel from behind. The LCD panel has first sections divided in a vertical direction and second sections divided in a horizontal direction. The LED backlight includes an LED light source and an edge-type light guide. The LED light source includes LEDs that are arranged along at least one of upper and lower sides of the light guide and are allocated to the second sections, respectively. A brightness of an image displayed in a given second section is used to control a light quantity of the corresponding LED. Each LED radially emits light so that light beams from adjacent ones of the LEDs intersect each other.
