In terms of the cost of LED backlights and traditional CCFL backlights, LED backlight technology has become mainstream, and it has been recognized by consumers for its advantages of mercury-free, low energy consumption, good color and long life. At the same time, the cost of small-size LED backlights has gradually dropped to a price very close to CCFL backlights. For consumers, having an energy-saving, environmentally-friendly and affordable product will naturally be sought after by consumers. With its unique and overwhelming advantages, LED backlight technology has gradually shown a strong application prospect. Then, for the sake of in-depth analysis of LED backlight technology and CCFL backlight technology, what are the advantages of LED backlight technology, why is it particularly popular in the display market? LED backlight technology: top ten leading edge LED as the backlight of LCD, compared with the traditional backlight technology, in addition to the advantages of the color gamut range, there are many unique advantages, summarized into ten aspects: 1) LED backlights have a better color gamut. Its color expression is stronger than CCFL backlight, which can make a good complement to the liquid crystal technology with insufficient display color, and the color reproduction effect is better. 2) LEDs can last up to 100,000 hours. Even if it is used continuously for 10 hours every day, it can be used continuously for 27 years, which greatly prolongs the service life of LCD TVs, and has the advantage of overwhelming plasma technology. 3) The brightness adjustment range is large. It is easy to achieve LED power control, unlike the minimum brightness of CCFL. Therefore, it is easy for the user to adjust the brightness of the display device to the most pleasing state, whether in a bright outdoor or a black room. 4) Perfect motion picture. The flashing illuminating frequency of the conventional CCFL lamp is low, and the dynamic scene may cause the picture to jump. The LED backlight can flexibly adjust the lighting frequency, and the frequency is much higher than the CCFL, so it can perfectly display the moving picture. 5) Real-time color management. Since the red, green and blue colors are independent of each other, it is easy to precisely control the current display color characteristics. 6) The white balance of the backlight can be adjusted while ensuring the overall contrast. When the user's video source is switched between the computer and the DVD player, the white balance can be easily adjusted between 9600K and 6500K without sacrificing brightness and contrast. 7) A continuous array of light sources can be provided for large screen sizes. LED is a kind of planar light source. The most basic light-emitting unit is a square package with a length of 3~5mm. It is easy to combine into a surface light source with a certain area. It has good brightness uniformity. If it is used as backlight of LCD TV. The source, the required auxiliary optics can be made very simple, and the screen brightness uniformity is even better. 8) Security. The LED uses a low voltage power supply of 5~24V, which is very safe and the design of the power supply module is quite simple. 9) Environmental protection. LED light source does not produce any radiation, and there is no toxic substance such as mercury. It can be said to be a green light source. 10) Earthquake resistance. The planar structure gives the LED a solid internal structure and excellent shock resistance.
Polyvinyl Chloride (PVC) insulated Electrical Cable is used in fixed wiring. As PVC is a thermoplastic polymer, PVC properties make it suitable for applications where the cables may be exposed to high or low temperatures. PVC insulation is frequently used owing to its good insulating properties but low corona resistance, and is best suited for low voltage cable and control cable. Compared to many other types of cables, PVC Electrical Cable tend to be stable, robust and durable.
