Abstract: The present application provides an anti-glare and anti-reflection film, a polarizer and a display panel. The anti-glare and anti-reflection film includes: a hardened layer; and first extinction particles dispersed in the hardened layer. The first extinction particles include a particle core, a first coating covering the particle core, and a second coating covering the first coating, and the first coating has a greater refractive index than that of the second coating. The anti-glare and anti-reflection film, polarizer and display panel provided by the present application can improve haze of a product itself and reduce reflectivity of a product itself, so as to improve quality of display screen.

Abstract: An optical film layer and a manufacturing method thereof, a polarizer, and a display panel are provided. The optical film layer includes a base layer and a group of particle layers arranged in the base layer. The group of particle layers includes multiple particle layers, and refractive indices of the multiple particle layers gradually decrease in a direction from a first side of the optical film layer to a second side of the optical film layer.

Abstract: Embodiments of the present disclosure are directed to a display module and a display device. The display module includes a display panel and an optical film arranged on an eminent side of the display panel. The optical film includes a first pattern layer and a second pattern layer disposed on a surface of the first pattern layer away from the display panel. The first pattern layer includes a plurality of first protrusions and a plurality of first recesses away from the display panel. The second pattern layer includes a plurality of second protrusions and a plurality of second recesses near first pattern layer. A refractive index of the first pattern layer is greater than a refractive index of the second pattern layer.

Abstract: Disclosed are a backlight module and a display device. The backlight module includes a plurality of light-emitting units disposed at intervals with one another, an optical film, and a concentrating structure. A slit is between two adjacent light-emitting units. The optical film is disposed at a side of the light-emitting unit. The concentrating structure is disposed at a side of the optical film close to the light-emitting unit and arranged in an area opposite to the slit. The concentrating structure comprises a plurality of protrusions.
