Problems solved by technology

The LCD reflective display device mainly uses ambient light or an external light source to provide the required brightness. Since the surface of the display screen is a mirror-like display structure, the light is scattered on the surface of the display screen when it is incident and emitted, which reduces the light efficiency and affects the display device. the overall brightness and affect the viewing angle of the display

Abstract

The present invention discloses a scattering film and an array substrate with the same. The scattering film comprises a substrate and a lens-like layer; the lens-like layer is arranged on the upper surface of the substrate; the lens-like lens layer is provided with a plurality of lens-like units; the light incoming surface and light outgoing surface of each lens-like unit are of lenticular structures; the plurality of lens-like units and the substrate define a plurality of cavities respectively; and the plurality of cavities are filled with a gas. According to the scattering film provided by the invention, the structural design of the lens-like layer and the substrate is adopted, and therefore, the reflection and scattering of light can be reduced through using the lens-like units of the lens-like layer, and luminous efficiency can be improved.

Description

Technical field [0001] The present invention relates to the technical field of reflective display devices, in particular to a scattering film and an array substrate with the scattering film. Background technique [0002] The breakdown structure of the existing LCD (Liquid Crystal Display, liquid crystal display) display device can be referred to figure 1 As shown, each part is a polarizer 101, a color film substrate 102, a liquid crystal 103, a TFT (Thin Film Transistor) substrate 104, a polarizer 101, and a backlight 105 in order from top to bottom. The decomposition structure of the existing LCD reflective display device can be referred to figure 2 As shown, each part is a scattering film 201, a polarizer 202, a color film substrate 203, a liquid crystal 204, a metal reflection layer 205, and a TFT substrate 206 in order from top to bottom. The LCD reflective display device mainly uses ambient light or an external light source to provide the required brightness. Because the su...
