Blue LED Square Shape Edge LED Backlight with Through-Hole in the Middle
Dr Pan: Welcome to DISPLAY Museum. I am Dr Pan, the curator of Museum.
Greg: Hello, Dr Pan. I am Greg. I came here to learn about LED backlight.
Dr Pan: Hello, Greg. LED backlight is the light source for LCD screen since it can’t emit light by itself.
Dr Pan: It is an optical component and non-standard product which is attached to the back of LCD.
Dr Pan: LED backlight can also be used as a separate lighting device.
Dr Pan: For example: backlight keyboard, smart lighting socket and currently fashionable backlight capacitive switch.
Dr Pan: The light emitted from the LED enters into the light guide plate and is evenly distributed to the surface.
Dr Pan: The reflection sheet reflects the light from the back of light guide plate to the surface
Dr Pan: and the diffusion sheet diffuses the light more evenly.
Dr Pan: The light blocking film prevents the light from leaking from the edges.
Dr Pan: Eventually, it turns a single light point into a uniformly illuminated board of light.
Greg: Dr Pan, I am wondering why LED backlight is so popular.
Dr Pan: There are many reasons. 1. It is highly customized.
Dr Pan: It can be made into different shapes and brightness according to different requirements.
Dr Pan: 2. It is more energy-saving. LED backlight saves at least 40% energy if it is compared with traditional CCFL backlight in civilian industry.
Dr Pan: 3. It is green and environmentally-friendly. It does not contain any environmentally harmful substances:
Dr Pan: for example, mercury.
Dr Pan: 4. It has a wider color gamut. It can display more vivid color and make a better color representation.
Dr Pan: 5. It has a longer serving time, 50 thousand hours.
Dr Pan: 6. It is lighter and thinner. The selling point of LED backlight products in the market is super thin, which meets the fashion needs of consumers.
Greg: Thank you, Dr Pan. Now I got it.
Dr Pan: Welcome to contact us if you have any question.
