[vc_row][vc_column][vc_column_text]EL backlight is an obsolete technology, it is disappearing. CCFL backlight is disappearing, too. They are both being replaced by LED Backlight. I have never heard anyone ask for a quote about CCFL backlight. But every now and then, I can hear my customers ask about EL backlight, so let us dig in and find… Continue reading EL Backlight vs LED Backlight

[vc_row][vc_column][vc_column_text] Hello everyone, Happy Chinese New Year! It has been a really long time since my last post. And how have you been? I have been receiving many RFQs about round and ring LED backlights recently, and I want to find a chance to explain how we make them. I will make everything very clear,… Continue reading The Ways We Make Round And Ring LED Backlight

[vc_row][vc_column][vc_column_text]LED backlight can not only be used as the light source for LCD panels, but can also be used as an illumination equipment, like LED panel lights, LED ceiling lights and LED light boxes. There is no essential distinction among these lights which are edge LED backlights. The only difference among them is the size.… Continue reading 8 Points We Must Confirm before We Quote a Custom LED Backlight

[vc_row][vc_column][vc_column_text]If we want to know about color production theory of LED backlight, we must learn about LED lamps first. The colors of LED backlight are composited by the colors of LED lamps we are going to use. First, how can we choose what kind of LED lamp we should use? Basically, there are 3 main… Continue reading LED Backlight Color Production Theory

[vc_row][vc_column][vc_column_text]Reflection Film for LED Backlight You May Not Know 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 large reflective ratio of metals. The amplitude of the light in the metal rapidly decays when… Continue reading Reflection Film for LED Backlight You May Not Know

[vc_row][vc_column][vc_column_text]The comparison of bottom LED backlight and edge LED backlight 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, almost all the clients I have seen choose edge LED backlight. Why? The… Continue reading Bottom LED Backlight vs Edge LED Backlight

[vc_row][vc_column][vc_column_text]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 shade film, etc. Therefore, we can see that backlight module consists of many optical films and the light which is emitted by LED lamps goes… Continue reading Optical Films for Backlight Module

[vc_row][vc_column][vc_column_text]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 a uniform surface light source in the LCD module. The theory of LCD diffusion film is that making the light pass through the medium of… Continue reading Diffusion Film for LED Backlight You May Not Know

[vc_row][vc_column][vc_column_text]Brightness enhancement film for LED Backlight 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 in the backlight module. It not only can concentrate the scattering light within a 70-degree angle in the front,… Continue reading Brightness Enhancement Film for LED Backlkight

[vc_row][vc_column][vc_column_text]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 the radiation of object is 0°and Kelvin is -273° C as the starting point of calculation. When the object is heated, the color temperature will… Continue reading What is Color Temperature
