Publication number: 20040046730Abstract: The invention is related to an LCD (Liquid Crystal Display) with a back light source characterized by light source local penetration. There is a reflective layer on the bottom of the LCD. The reflective layer contains some light channels. A micro lens-film is placed between the LCD and the back light source. The micro lens-film contains some light collection sections in such a way that individual light collection sections are opposite individual light channels. The invention has two merits. Firstly, the reflective layer reflects incident daylight greatly so as to help illuminate the LCD. Secondly, the light emitted by the back light source is condensed by the light collection sections before passing through the light channels, so that it helps illuminate the LCD. Not only is the LCD illuminated better, but the images it shows also have better contrast under daylight. Hence, the images displayed on the LCD screens are greatly improved.Type: ApplicationFiled: August 21, 2002Publication date: March 11, 2004Inventors: Kazuhiro Miyashita, Wen-Hsiang Chang, Yen-Chuan Chu, Yu-Bing Liu
