Abstract

This paper analyzes the principle of liquid crystal display backlight system illuminating by light emitting diode (LED) and serial kinds of structure of light guide plate. The density of diffusion dots on the light guide plate is an important factor to determine symmetric luminance and percentage of light transmission of LGP surface. Through changing the structure of light-guide plate, we can decrease the loss of light and improve the distribution of light.
