Low Power Liquid Crystal Display Backlight.

Abstract

A liquid crystal display panel is disclosed having a backlight for providing high brightness, uniformity of illumination intensity, high efficiency, and long battery life, and which can be manufactured at a low cost. The display device includes a liquid crystal display panel, a light source for illuminating the liquid crystal panel, a light passage member which can be formed of a transparent material disposed between the liquid crystal panel and the light source. The light source inlet side of the light passage member is formed with a recess with the thickness being reduced at the region diametrically opposed to the light source. A light reflecting member reflects light from the light source. Within the photoconductor, two or more of the wedged shaped photo conductor can be used for increased area of coverage. Patent applications. (JHD)
