Abstract

A brightness enhancement film used for coating quantum dots comprises a basal film. The basal film is coated with two layers of structures. A first layer of structure is thermal-curing molding acrylic resin containing the quantum dots and diffusion particles and is used for preventing water so as to protect quantum dot stability. A second layer of structure is UV epoxy resin which forms a prism structure through UV curing and is located on a first layer mechanism and is used for preventing oxygen so as to protect the quantum dot stability. In the invention, the acrylic resin and the epoxy resin are used to prevent water and oxygen, and the quantum dots are placed below the prism structure so that reflected large-angle incident light can be used to excite the quantum dots at a second time. Sensitivity of the quantum dots to water and oxygen is overcome and the quantum dots are fully excited. A fluorescence yield of the quantum dots is increased so that color display with a large color domain and high brightness is acquired.

Description

technical field [0001] The invention relates to a brightness enhancing film. Background technique [0002] Liquid crystal display (LCD) is the most mature display technology at present, and it will also be the mainstream display technology in the next ten years. However, the color gamut of ordinary LCD TVs can only reach 72% now, and cannot display 100% of the color gamut, resulting in distorted colors and chromatic aberrations of many scenes and characters, which have a great impact on people's viewing. The improvement of color saturation and color gamut of liquid crystal displays is of great significance. [0003] Quantum dots are extremely small semiconductor crystals with a size of about 3 to 12 nanometers, composed of only a few atoms, so their activities are limited to a limited range and lose their original semiconductor characteristics. It is also because it can only move in a small space, so it is easy to make it glow by affecting its energy state. [0004] The f...
