Abstract

A brightness enhancement film and its manufacturing method, a backlight module and a display device, wherein the brightness enhancement film includes a base material, a soft rubber layer and a prism structure layer. The manufacturing method includes coating a layer of soft resin on the surface of the base material; curing the soft resin to form a soft glue layer; coating a layer of hard resin on the surface of the soft glue layer; The mold presses the hard resin to form a structure with several preset prism shapes; solidifies the several structures with preset prism shapes to form a plurality of first prisms, and the plurality of first prisms form a prism structure layer. A backlight module, including any one of the above prism structures. A display device, comprising any one of the above backlight modules. The above-mentioned brightness enhancement film and its manufacturing method, backlight module and display device reduce the damage of the brightness enhancement film, reduce the occurrence of white spots or white spots when the backlight module is used, and reduce the occurrence probability of the display effect being affected.

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