How is the diffuser sheet applicated in LCD and LED?

Types of diffuser sheets

The types of Diffuser sheets can be divided into gas diffusion plates, sound diffusion plates, liquid diffusion plates, polycarbonate diffuser sheets, taste diffusion plates, and materials like lexan polycarbonate which are capable of uniformly dispersing molecules are collectively referred to as diffuser sheets (most of them are polycarbonate panels).



How does the diffuser sheet work?

If you wonder know why it can be used diffusely, you need to know how the diffuser pc sheet works. Before you can understand how a diffuser diffuses, you must first understand two principles, one is the principle of reflection and the other is the principle of refraction. The principle of reflection is that when light from one medium to another smooth interface, part of the light reflected through the interface, the other part of the light refracted through the interface of another medium. The incident Angle of light is equal to the reflected Angle, and the reflected light is in the same plane and on both sides of the normal of the incident plane. And the principle of refraction is that the refracted light is in the plane of the incident light and the normal light, and the ratio of the refracted light and the normal light to the incident angle and the sine of the refraction angle is a constant. Polycarbonate led light diffuser sheet, a principle like this, can be widely used in liquid crystal display, LED lighting and imaging display systems.

Diffuser sheet shows its characteristics in liquid crystal display

The diffuser like polycarbonate light diffuser is one of the main applications of liquid crystal display. The diffusion sheet in the liquid crystal display application is mainly due to its heat resistance, flame retardant, light transmittance and other advantages, followed by the diffusion polycarbonate panel in liquid crystal display performance. Out of the features, let's talk about the performance features.


1. Light source diffusibility: Suitable for direct-lit backlight modules, with high brightness and high diffusivity, which can improve the uniform diffusion effect of the backlight.


2. Light transmittance: Excellent light transmittance occurs with high brightness.


3. Dimensional stability: minimum water absorption, good dimensional stability in wet environment, and normal use in the temperature range of -40 ° C ~ 125 ° C.


4. Antistatic property: It has good antistatic performance and prevents dust from adsorbing.

This is the performance of the diffuser sheet on the LCD display. It is precisely because of these characteristics that the light diffuser is selected in the liquid crystal display.


The main application of the Diffuser sheet is on LED lighting and liquid crystal display, which is used to fully scatter the incident light for a softer and evener illumination. However, LED lighting has certain requirements for the use of diffuser sheets. The main requirements are as follows. Contact us for the polycarbonate sheet price now!
