Portable liquid crystal display and the tablet PC

[0001] This application claims the priority benefit of Taiwan application serial no. 93127818, filed on Sep. 15, 2004.

[0002] The present invention relates generally to a portable liquid crystal display and a Tablet PC, and more particularly, to a portable liquid crystal display and a Tablet PC with an easy-to-carry opening or gap.

[0003] Following the fast and intensive development of multi-media technology, the fashion of image delivering has transformed from analog to digital transmission. Besides, to fit the modern life style, the size of video or image devices has become minimized. Conventional cathode Ray Tube (CRT) display has the advantages of excellent display quality and low manufacturing cost; however, the CRT cannot meet the requirement of a thinner, lighter display with lower power consumption due to the structure of the electronic chamber therein. Additionally, the radiation emitted is still a concern for consumers. Therefore, with the improvement of optoelectronics and semiconductor technology, Flat Panel Display (FPD) is thriving in the market. Among various FPD products, liquid crystal display (LCD) becomes the mainstream display to replace the conventional cathode ray tube as it can be operated under low voltage without radiation, and has a thinner and lighter body.

[0004] The more development of liquid crystal display technology, the more applications are explored. The most popular applications are mobile phones, personal digital assistants (PDAs), liquid crystal display monitor (LCD monitor), liquid crystal display television (LCD TV), Notebook, Tablet PC . . . etc.
