Abstract
Light-emitting diodes (LEDs) have been widely used in liquid
crystal display (LCD) backlight modules. In general, the light emitted
by the LED backlight modules is not un-polarized light. However, our
experiment results and analysis show that the light is partial polarization.
The characteristics of partial polarization obtained in the experiment
and analysis are utilized to increase the brightness of LCD backlight
module, and then the results of this study demonstrate that the brightness
can be increased by 46%. Thus, this study provides a method to increase
the brightness of LCD backlight modules.
