Problems solved by technology

[0008] However, the above-mentioned structure of combining the traditional back shell is to manufacture the dust cover separately, so in addition to the need to manufacture the dust cover separately, there is also a problem of installing the dust cover to the back case.
In addition, because the back shell and the dust cover are manufactured separately, the cost of the metal mold will inevitably increase, and the increase in the installation project and the prolongation of the manufacturing process will increase the cost of the product. Therefore, it is necessary to provide an effective Rear shell and dust cover structure that can shorten the construction schedule and reduce costs while preventing dust from entering

Embodiment Construction

[0023] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0024] image 3 It is a schematic structural view of the dustproof cover and the rear shell of the present invention as one. As seen on the same drawing, the structure of the rear shell of the liquid crystal rear projection TV set of the present invention is composed of an optical engine that generates light including image signals 130; reflection mirror 140 reflecting the image signal light generated by the above-mentioned optical engine 130; a screen for displaying images by the light reflected by the above-mentioned reflection mirror 140; isolating the above-mentioned optical engine 130 and the reflection mirror 140 to prevent dust cover from entering 120 compositions.

[0025] At this time, the above-mentioned dustproof cover 120 is integrated with the rear case 110 . It is made of gold-shaped baskets made of synthetic resin.

Abstract

This invention relates to LCD back projection TV and to one TV back shell structure to prevent outside dust into reflection lens, which comprises the following parts: Optical engine of image signal light; reflection lens to send light by the optical engine; optical display image screen to receive the above reflection lens light; dust prevent cover with back shell to prevent dust to isolate the above optical engine and reflection lens to Reduce materials charges and process time.

Description

technical field [0001] The invention relates to a liquid crystal rear-projection television, in particular to a rear shell structure of the liquid crystal rear-projection television which prevents dust entering from the outside from adhering to the reflection mirror. Background technique [0002] Now, as a general display device, there are CRT TVs, CRT rear projection TVs, liquid crystal display TVs, liquid crystal display rear projection TVs, plasma TVs and the like. [0003] The above-mentioned liquid crystal display rear projection TV is to enlarge and display the image on the screen after the image information generated by the optical engine is projected through the projection mirror. [0004] Below, for LCD rear-projection TVs whose demand has increased sharply recently, refer to figure 1 described as follows. [0005] figure 1 It is a schematic diagram of the structure of a general LCD rear-projection TV. As shown in the figure, the LCD rear-projection TV is an opti...
