Reflection film can be divided into metal reflection film, full dielectric reflection film and metal-dielectric reflection film which can increase the reflectivity of the film surface. Generally, there is a

LED light source is the best for all the light sources of backlight. The thickness of LED backlight is based on two important factors: the client requirements and the design requirements. Moreover,

The Introduction for Backlight Unit Structure Backlight module is mainly composed of light source (LED lamps), light guide plate, reflection film, diffusion film, brightness enhancement film / prism sheet, light

The Theory and Function of Diffusion Film The diffusion film is the spread material that transforms the linear light source of CCFL or the point light source of LED into

BEF which is abbreviated for Brightness Enhancement Film and is also called Prism Sheet. It is the key component of backlight module and occupy the highest proportion of the cost

The color temperature is that human eyes see the variation of the color when light waves are in different energy. We regard Kelvin as the unit for color temperature, and

1. LED Backlight is dominating the market while CCFL Backlight is disappearing The  power consumption of LED backlight is much lower than CCFL backlight’s in the same amount of brightness.  

1. Introduction of Light Guide Plate The main material of light guide plate is an optical acrylic sheet whose chemical name is polymethyl methacrylate (PMMA) and its weight is 1190

1. What is backlight bleeding? It is a very common phenomenon that liquid crystal display panel and the frame are not tight enough that some lights are transmittance out. It
