Abstract

The invention discloses a bright enhancement film, a manufacturing method therefor, a backlight module group, and display equipment. The bright enhancement film comprises a base material, a soft glue layer, and a prism structure layer. The manufacturing method comprises the steps: coating the surface of the base material with a soft resin layer; solidifying the soft resin, and forming the soft glue layer; coating the surface of the soft glue layer with a hard resin layer; carrying out the compression molding of the hard resin layer through a die which has a complementary structure with the prism structure layer, and enabling the hard resin layer to form a structure which has a plurality of preset prism shapes; solidifying the structure with the plurality of preset prism shapes to form a plurality of first prisms, wherein the plurality of first prisms form a prism structure layer. The backlight module group comprises any one prism structure above. The display equipment comprises any one backlight module group above. According to the invention, the damage to the bright enhancement film is reduced, and the white points or white spots generated during the use of the backlight module group are reduced. Moreover, the possibility that the display equipment of a display is affected is reduced.

Description

technical field

[0001] The invention relates to the field of inventive backlight film materials, in particular to a light enhancement film and a manufacturing method thereof, a backlight module and a display device. Background technique

[0002] At present, optical films have been widely used in the fields of optics and optoelectronics technology to manufacture various optical instruments. It is especially widely used in the field of backlight modules. For example, the light enhancement film in the backlight module can be used to gather the light emitted by the light source, especially in display devices such as liquid crystal displays. For example, in LCM (LCD Module, LCD display module, Also known as the backlight module), the brightness enhancement film is often used to increase the display brightness and save the energy of the display battery equipment.

[0003] The light-enhancing film is usually composed of a substrate and a condensing prism structure layer. The subst...
