Abstract
A backlight system and an LCD employing the backlight system. The backlight system includes a plurality of light emitting devices arranged on a base plate to form a plurality of lines each including a plurality of light emitting devices, and a light guide panel having a sidewall spaced apart from the plurality of light emitting devices such that light incident from the plurality of light emitting devices is dispersed by inner reflection, and a scattering region formed adjacent to the base plate such that light incident into the scattering region is irregularly reflected to emit in a direction away from the base plate.
Claims49
A backlight system comprising:
- a plurality of light emitting devices arranged on a base plate to form a plurality of lines;
- and
- a light guide panel having a sidewall spaced apart from the plurality of light emitting devices such that light incident from the plurality of light emitting devices is dispersed by inner reflection, and a scattering region formed adjacent to the base plate such that light incident into the scattering region is irregularly reflected to be emitted away from the base plate.
An LCD comprising:
- a liquid crystal panel;
- and
- a backlight system to irradiate light toward the liquid crystal panel,
- wherein the backlight system comprises:
- a plurality of light emitting devices arranged on a base plate to form a plurality of lines;
- and
- a light guide panel having a sidewall spaced apart from the plurality of light emitting devices such that light incident from the plurality of light emitting devices is dispersed by inner reflection, and a scattering region formed adjacent to the base plate such that light incident into the scattering region is irregularly reflected to be emitted away from the base plate.
An apparatus comprising:
- a plurality of light emitting devices arranged on a base plate to emit light by inner reflection;
- and
- at least one light guide panel to guide the light emitted by the plurality of light emitting devices, the light guide panel including a scattering region having at least two components that vary in width based on a distance away from each of the plurality of light emitting devices.
An apparatus comprising:
- at least two lines of light emitting devices denoted ‘n’, arranged on a base plate, where each line includes at least two light emitting devices;
- and
- a plurality of light guide panels each disposed in parallel along a side of a respective line of light emitting devices to guide the light emitted by the plurality of light emitting devices, where the number of light guide panels is ‘n+1’.
A light guide panel usable with a backlight system for a liquid crystal display, comprising:
- a plurality of sidewalls, wherein pairs of the plurality of side walls can accommodate a respective light emitting device;
- and
- a plurality of scattering regions extending in parallel along the length of the light guide panel to irregularly reflect incident light emitted from the light emitting devices and internally reflected therein and to project the light out of a lengthwise side of the light guide panel.
