Backlight module suitable for edge-removing side light leakage of ultra-narrow frame

Abstract

The invention discloses a backlight module suitable for edge-removing side light leakage of an ultra-narrow frame. The backlight module comprises a shell, baffles are fixedly connected to the two sides of the upper end of the shell, expansion rubber is fixedly connected to the side ends of the two baffles, a liquid crystal display screen is arranged between the lower ends of the two baffles, and the two sides of the liquid crystal display screen are sleeved with sealing plates; a diffusion brightness enhancement module is arranged on the lower side of the liquid crystal display screen and composed of a diffusion film and a brightness enhancement film, a light guide plate is arranged on the lower side of the diffusion brightness enhancement module, light bars are arranged on the two sides of the light guide plate, a back plate is fixedly connected to the lower side of the shell, and a supporting plate is arranged at the upper end of the back plate and is of a U-shaped structure. The supporting plate is fixedly connected with reflector plates at the light bars and the light guide plate. According to the invention, through multiple measures, light at the side edges of the liquid crystal display screen can be refracted and sealed, and the situation that light leaks from the side edges is avoided.

Description

technical field [0001] The invention relates to the field of display screens, in particular to a backlight module suitable for ultra-narrow frames and side light leakage. Background technique [0002] With the development of electronic technology and liquid crystal display technology, electronic screens are gradually developing towards thinner and full screen. Especially in recent years, with the overall development of our country's economy, we have begun to vigorously carry out infrastructure construction, and gradually realized the Internet to every household. More and more families have begun to use large-screen LCD TVs or computers. The panels of LCD TVs and computers are divided into two structures, LCD and LED. Among them, LCD liquid crystal screens are widely used because of their easy processing, good color performance and low price. Since the LCD liquid crystal screen is used for display and does not emit light by itself, a backlight module is required to provide s...
