LOW PROFILE BACKLIGHT OPTIMIZED FOR LIQUID CRYSTAL DISPLAYS |
摘要 |
An apparatus is disclosed that provides back light for liquid crystal displays ("LCD"). The apparatus includes an electrodeless lamp disposed in a cabinet for generating light; and a reflector disposed on one side of the electrodeless lamp for directing light from the lamp in the direction of the LCD. The reflector further includes a surface profile that provides a uniform distribution of light intensity into the LCD. The reflector further is adjacent and in near contact with the lamp to provide a minimum depth behind the lamp. An alternate embodiment of the invention includes an IR reflector disposed between the electrodeless lamp and a diffuser, which is located adjacent to the LCD screen. |
