In the second half of 2010, the infinite CCFL LCD display was gradually replaced by LED , and the popularity of LED has been the result of the nailing. At the beginning of 2011, with the arrival of the Spring Festival promotion, a variety of LED displays have been listed, consumers for LED The level of acceptance has also risen.
At present, the advantages of LED lighting technology have been deeply rooted in people's minds. Energy-saving, low-temperature, non-radiative, long-life and other characteristics make LED lighting technology widely used in the manufacture of liquid crystal displays. First-line display manufacturers have introduced a variety of color performance, brightness balance, low energy consumption. The LED display products have launched another round of new competition since the LCD.
LED lighting advantage
LED lighting technology has significant color advantages, so it is favored in display manufacturing. Currently obsolete CCFL (Cold Cathode Backlight) technology, due to its own spectrum limitation, the color gamut range is greatly limited, the best performance is only about 70% of the NTSC color gamut, and the higher color gamut effect is more expensive. cost.
However, the use of LEDs as backlights is completely different, because LEDs (light-emitting diodes) cover a wider range of chromatograms, more uniform light-emitting area, and the normal color gamut can easily reach 100% to 130%, unlike traditional CCFL backlights. The same 30% color loss. Therefore, the color of the LED-backlit display is more full, the details of the picture are clearer, and the color transition is more natural.
Better brightness is more energy efficient
In addition to the advantages of illumination, the biggest benefit of LED backlight display is to ensure that the brightness difference at each point of the screen is well controlled and does not require too much power. Better brightness uniformity allows the image on the LED screen to have a richer level than a simple black block.
