Abstract

The invention relates to a back projection TV, which comprises a screen, a protective glass, and a front frame, while the screen is cling to the protective glass and fixed at one side of front frame. The invention also provides a relative mounting method, which comprises: mounting the protective glass into front frame; horizontally arranging the screen on the protective glass; arranging screen compress bars on the four edges of screen; fixing the screen compress bars, screen and protective glass on the front frame, to avoid hurting screen; the protective glass and screen are at the same side of front frame, to be cling, to avoid dust entering to the interlayer between them; the sponge bar adhered on the screen compress bar has flexibility, with adjustable mounting error, to reduce the breakage caused by over compressing the protective glass and screen, with sealing function.

Description

【Technical field】 [0001] The invention relates to a rear-projection TV, and the invention also relates to an installation method of a rear-projection TV. 【Background technique】 [0002] Among the high-end TVs on the market, in the large screen size segment of 50 to 80 inches, rear-projection TVs have a large share due to their excellent picture quality and relatively low prices. Existing rear projection TVs include a screen, protective glass, and a front frame. The protective glass is fastened on the front side of the front frame by screws, the screen is located on the back side of the front frame, and there are pressure strips or top blocks around the screen to fix the screen on the front frame. The disadvantage of this rear-projection TV is that the distance between the screen and the glass is large, which affects the clarity. In addition, for the sake of appearance, it is necessary to do screen printing ink processing around the protective glass, so that the transparent...
