The use of LED Backlightt

LED Backlightt, service life is longer than EL (more than 5000 hours), and the use of dc voltage, usually used in small monochrome display, such as telephone, remote control, microwave oven, air conditioner, instruments and meters, stereo audio equipment, etc.

However, its brightness is not enough to provide a backlight source for large transmission displays. LED Backlightting is basically the same structure as CCFL backlight. The main difference is that LED is light source and CCFL is line light source.

Small cold cathode fluorescent lamp (CCFL) provides for large LED Backlightt brightness and life (and lighting control ability), it is that it is still backlighting most commonly used method. But heat accumulation is a concern.

LED Backlightt is a non-luminous display device, which needs to be used by the back light source to achieve the display function.

One, the fuselage is thin, save the space: compared with the relatively bulky CRT display, the liquid crystal display is only one third of the space of the former.

2. Power saving, no heat generation: it belongs to low-power electrical products, which can be completely unburned, relative to CRT display, because the display technology inevitably produces high temperature.

No radiation, good health: the LCD is completely free of radiation, which is a boon for people working in front of computers all day.

4. The picture is soft and unhurt: unlike CRT technology, the LCD screen will not blink, which can reduce the damage of the monitor to the eyes, and the eyes will not be tired easily.

China has become the world's largest producer of LED Backlightts. Statistics: China's display industry sales in 2000 were about 407 billion yuan. Liquid crystal display is 6 billion yuan.

A few years ago, China's display industry had a total industrial output of about 60 billion yuan, of which the liquid crystal display was about 80 ~ 10 billion yuan. China is a huge potential market for liquid crystal display devices.

The technology threshold and capital threshold of LED Backlightt industry are very low and chaoyang industry, so the initial industrial barriers are not high enough to attract many small and medium-sized manufacturers into this field. However, due to the back light module is not can produce more goods, under the LED Backlightt application more hasten is extensive, the size and specifications of products are more and more, among them, the specifications of the guide plate, the size and thickness of each panel makers are not the same, backlight module manufacturers must according to the need of each customer, in order to design a variety of different backlight module.

Depending on the back light, LED Backlightt can be divided into two kinds of of CCFL and LED, many users believe that LED and LED Backlightt, the liquid crystal display can be divided into that actually listed on the Angle error.

Currently on the market of LED Backlightt is not really a LED Backlightt, accurately is LED backlit LCD monitor, LCD panel is still the traditional LED display screen, backlight in a sense, that contains the nature of the fraud!

For liquid crystal display, the most important is the key to the LCD panel and a backlight type, and the display of the LCD panel on the market generally use TFT panel, is the same, the difference between LED and LED Backlightt is just their different backlight: LED Backlightt and CCFL backlight (fluorescent), diodes and the cold cathode tube, respectively.

CCFL is also called cold cathode fluorescent lamp tube, which is usually referred to as the LCD monitor with cold cathode fluorescent lamp tube as a backlight source, the advantage of CCFL is that the color is good, but the power consumption is higher.

LED is often referred to as the LCD, which is used as a backlight source with LED, which is usually LED Backlightt. The advantage of LED Backlightt is small volume, low power consumption, so using LED Backlightt lamp as backlight, can achieve high brightness while balancing light and light. However, there are also some deficiencies, mainly because the color performance is worse than the CCFL, so the professional drawing LED Backlightt bulbs still use the traditional CCFL as a backlight source.
