Abstract

The invention relates to the field of optical films, in particular to a composition and a brightness enhancement film. The composition and the brightness enhancement film are provided in order to solve the problem of low refractive index of a composition for preparing high-brightness optical films. The composition comprises resin and zirconium oxide particles in weight percentage content of 10%-50%. The brightness enhancement film comprises a brightness enhancement layer, and the brightness enhancement layer comprises resin and zirconium oxide particles in weight accounting for 10%-50% of thatof the brightness enhancement layer. The refractive index of the composition is larger than or equal to 1.60, the brightness enhancement film prepared from the composition is high in brightness, andthe problem that an existing brightness enhancement film is insufficient in brightness and fails to meet energy saving of mobile display equipment can be solved. A preparation method of the composition is simple in process, easy in operation and convenient for industrial production.

Description

technical field

[0001] The invention relates to the field of optical films, more specifically to a composition and a brightness enhancing film. Background technique

[0002] Liquid crystal display panels have been widely used in the display screens of computers, mobile phones, televisions, navigators, digital cameras and some instruments. Since the liquid crystal panel itself does not emit light, the backlight module, as one of the key components of the liquid crystal display panel, plays a role in providing sufficient brightness and uniform light.

[0003] However, in mobile display devices, such as mobile phones, tablet computers (Pads), etc., the power supply of the display device is a charged storage battery. In order to increase the service life of the battery after charging, the backlight module of the display device needs to meet the more efficient performance of low voltage and high brightness, so as to save energy and reduce the consumption of battery power. The m...
