Frame structure device of narrow-frame liquid crystal display television

Abstract

The invention discloses a frame structure device of a narrow-frame liquid crystal display television, which comprises liquid crystal glass, a light guide plate, a back plate, a frame, a reflector plate and an optical film sheet which is arranged on the light emergent side of the light guide plate. The frame is of an aluminum profile and a protruding part is arranged inwardly on the inner side wall of the frame, so that several dressing grooves with different widths are formed in the inner side wall of the aluminum profile. U-shaped elastic materials are also inlaid into the grooves. The light guide plate, the back plate, the optical film sheet and the reflector plate are inserted to grooves made of the U-shaped elastic materials. A circle of elastic sponge is pasted on an inner opening of a part close to the liquid crystal glass on the aluminum profile. PVC (Polyvinyl Chloride) for decoration is pasted on the external surface of the aluminum profile, and a screw hole used for fixing a rear cover is designed in the aluminum profile. Surface frames and screen frames are substituted by aluminum profiles in the structure provided by the invention, and a very narrow frame effect can be obtained.

Description

technical field [0001] The invention relates to a TV, in particular to a frame structure device of a narrow frame liquid crystal TV for a flat panel TV. Background technique [0002] With the development of LCD screen technology, the borders of LED screens are becoming narrower and narrower. [0003] Bezel-less flat-screen TVs or ultra-narrow bezel flat-screen TVs. The narrowing of the frame of the TV greatly improves the appearance of the whole machine, making it more aesthetically pleasing in design with a thinner and wider screen. Narrow bezel design has become the general trend, but the space occupied by the traditional assembly method is relatively too large The assembly structure of the flat-panel TV is usually divided into three parts: the front shell, the rear shell, and the screen. The front shell is a frame with a front frame and a side frame. The front frame is narrowed, and the front of the screen Fit the front frame, the side frame is on the side of the screen...

AI Technical Summary

Problems solved by technology

In the backlight module with the above structure, when the optical film is heated and wrinkled, a gap will be formed between the optical film and the light guide plate in some areas, which will cause the light emitted by the backlight source (such as LED lamp) to enter the gap, resulting in light leakage
