Problems solved by technology
In addition, when the plastic frame and the iron frame are installed with each other, they are usually assembled with additional connecting and locking parts to realize the fixing of the plastic frame and the iron frame. Since the additional connecting and locking parts are required, the manufacturing cost will be increased, and the installation will also be difficult. It is more troublesome, and it is easy to cause light leakage

The invention relates to the technical field of photoelectric display, in particular to a brightness enhancement film with a light leakage prevention function, which comprises a lower iron frame and is characterized in that an LED light emitting assembly is arranged right above the lower iron frame, a rubber frame is arranged right above the LED light emitting assembly, a reflector plate is arranged right above the rubber frame, a light guide plate is arranged right above the reflector plate, and a diffusion plate is arranged right above the light guide plate. A lower brightness enhancement film is arranged over the diffusion film, an upper brightness enhancement film is arranged over the brightness enhancement film, and an upper iron frame is arranged over the upper brightness enhancementfilm. The buckles are arranged on the rubber frame, the corresponding clamping holes are formed in the corresponding lower iron frame, assembly convenience is improved through direct buckling of thebuckles and the clamping holes, and the LED lamp is stable and reliable after assembly, not prone to loosening, not prone to light leakage, simple in structure and high in practicability.
Description
technical field [0001] The invention relates to the field of optoelectronic display technology, in particular to a brightness enhancement sheet with the function of preventing light leakage. Background technique [0002] With the rapid development of liquid crystal display technology, the application of light emitting diode (light emitting diode, referred to as LED) backlight modules has gradually expanded from telephones, game consoles and mobile phones to portable products, audio players, and even larger TVs and monitors. Among them, the demand for ultra-thin LED backlight modules is increasing, its development is also faster, and its application is more common. [0003] According to the arrangement of the light source, the backlight module device used in the liquid crystal display device is divided into a direct type or a side type backlight module device. The backlight module is the light source that provides the LCD panel. It is mainly composed of light source, light...
