Abstract

The invention discloses an optical screen structure of an ultrathin laser television. The optical screen structure comprises a projection optical film, a supporting back plate, a first adhesive and ahanging frame assembly, The projection optical film is bonded to the front face of the supporting back plate through a first adhesive, and the hanger assembly is fixed to the back face of the supporting back plate. According to the optical screen structure of the ultra-thin laser television, the thicknesses of the ultra-large-size screen main body and the frame can be reduced to be within 6mm, andthe ultra-large-size, ultra-narrow-frame and ultra-thin full-screen design of the laser television screen is realized while the flatness of the screen main body is ensured.

Description

technical field [0001] The invention relates to the technical field of image display, in particular to an ultra-thin laser TV optical screen structure. Background technique [0002] Laser TV usually adopts ultra-short-throw projection, and the projection ratio is usually ≤0.233. The product is usually placed on the customer's TV cabinet or hoisted directly above the screen. It is precisely because of the characteristics of ultra-short-throw projection that the projection size is generally super large: 70~ 300-inch class, which has very high requirements for the flatness of the screen or projection surface; in order to ensure the flatness and strength of the screen, the traditional laser TV optical screen in the industry usually uses aluminum honeycomb board as the base material, and adopts riveting method on the back of the honeycomb board Install the suspension structural parts for suspension, and the main body of the screen undertakes the gravity of the screen itself; or a...
