20100225845	Protection framework for liquid crystal display - The present invention provides a protection framework for liquid crystal display. It is composed of an upper, a lower, a right and a left frames, and each of the length of four frames is respectively matched with the length of each side edge of liquid crystal display. The four frames are engaged together with four connecting members each provided between the adjacent frames thereby forming an integral framework for LCD screen. Since the length of each frame can be modified to match the variously sized LCD screen so as to save preparation of a lot of different molds and jigs for fabrication of frameworks as that is necessary in conventional technique, the production cost can be greatly reduced.	09-09-2010
