Analyze the light that is free on TV!

TV is a product with strong technology and technology. The appearance of the hero is by no means what you can see. You may have seen a lot of articles about the internal structure of the TV. It is not technically strong or long-term, redundant and complicated to read. The internal structure of the TV is indeed worth exploring. Simple depictions and explanations can give a clearer understanding of the mystery. Today we will talk about the soul center of TV in the easy-to-understand language.

The new generation of flat-panel TVs no longer need the long distance penetrated by the electron gun, but the principle of using a thin light source to illuminate the front TV panel, so the size of the TV is greatly reduced. The current light source is divided into CCFL cold cathode fluorescent tube and led two light sources emitting diode, look name was scare, CCFL lamp can be regarded as general that we use, the required drive power emit bright white light and the LCD screen, but there is good place is a fluorescent tube Power consumption is high and short-lived, and is replaced by LEDs after a while.

The backlight module composed of the new LED light source is mainly divided into a light source group, a light guide plate, a reflection sheet, a reflective brightness enhancement film, a diamond lens and a diffusion sheet. The most important thing for the TV to remove the liquid crystal panel is the backlight module, and the LED is a single piece. The small sequins of the LEDs, the brightness and life of the light source are much better than the CCFL, and the coverage is larger. At present, the LED backlight module is divided into two types: direct type and side-in type, and due to the new quantum dot technology. Joined, the backlight of the quantum dot TV has been upgraded. We will not discuss how OLED TVs emit light for the time being because they do not require backlighting but self-luminous.
