Must-see tips! Kimoto tells you what are the functions of diffusion films?
Kimoto Mylar film, aluminum crystal glue, PORON products, functional characteristics and material comparison, are widely used in notebook computers, game consoles, game console handles, stereo Bluetooth headsets, mobile phones, cameras, lighting, LEDs, projectors, liquid crystal displays, etc. Relevant electronic products; from the selection of raw materials and auxiliary materials, testing, procurement, production process, etc., there are complete and strict implementation of technical system documents and technological processes.
Kimoto introduced the role of the diffuser:
The diffuser is one of the components of the backlight module. The diffuser is also called the diffuser. Its main function is to provide a uniform surface light source for the display.
The diffuser is one of the components of the backlight module. The diffuser is also called the diffuser. Its main function is to provide a uniform surface light source for the display. The base material needs to choose a material with high light transmittance such as PET/PC/PMMA. Generally, the traditional diffusion film mainly incorporates chemical particles into the diffusion film base material as scattering particles, while the existing diffusion plate has fine particles dispersed between the finger layers, so the light will pass through the diffusion layer. It will continue to pass through two media with different refractive indexes. At the same time, the light will undergo many refraction, reflection and scattering phenomena, which will cause the effect of optical diffusion.
The structure of the diffusion sheet is usually an antistatic coating layer, a PET substrate, and a diffusion layer from bottom to top.
The composition of the material of the backlight module from bottom to top is a reflective sheet, a light guide plate, a lower diffuser, a prism sheet, and an upper diffuser. The working principle of the diffuser is to atomize the light source by the refraction and reflection of the diffuser, and concentrate the light from a small angle to the front to increase the front brightness. The lower diffuser mainly concentrates the light emitted from the light guide plate and uniformly projects it onto the prism sheet, while the main function of the upper diffuser is to atomize the light emitted by the prism sheet and evenly transmit the light. At the same time, the upper expansion can also be used. To protect the prism sheet.
