Diffuser screen module, display screen and mobile terminal

Abstract

The invention provides a diffuser screen module, a display screen and a mobile terminal. The diffuser screen module comprises a module body, a display panel located in the module body and a light guide plate located between the display panel and the bottom surface of the module body, and further comprises a lower polaroid, and only a diffusion film is arranged between the light guide plate and the lower polaroid. At least one layer of diffusion film is arranged, so that good visual experience is brought to a user, the light intensity per unit area is reduced, and the vision health of the user is protected. The display screen comprises the diffuser screen module, a touch panel and an upper polaroid, so that the display defect of a traditional display screen is overcome; a backlight module in the traditional display screen is changed into the diffuser screen module of the device, so that the light radiation area is increased. The mobile terminal provided by the invention comprises the above display screen, so that the eye health of the user is protected.

Description

technical field [0001] The invention relates to the technical field of backlight modules, in particular to a scattering screen module, a display screen and a mobile terminal. Background technique [0002] At present, 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 smaller Large TV and monitor. Among them, the demand for ultra-thin LED backlight modules is increasing, its development is also faster, and its application is more common. 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 guide p...

Problems solved by technology

[0003] At present, the traditional backlight module places a light guide plate on the reflector, and then sets a brightness enhancement film component between the light guide plate and the upper polarizer. This kind of backlight module blindly pursues display brightness by setting a brightness enhancement film, and the display screen has high brightness. , glare, easy to use eye fatigue, blue light damages eyesight, poor experience for end consumers
