LED applied to backlight module has the advantage of power saving

by:Toponetech     2021-06-23
Abstract: LED used in backlight module has the advantage of power saving. LED used in backlight module as a light source, replacing the traditional cold cathode fluorescent lamp (CCFL), not only has the advantages of light and power saving, small size, long life, low voltage, and fast start-up. In addition to the benefits, it also has the concept of environmental protection. For notebook computers, depending on the processor and size, the use of LEDs in the backlight module has the advantage of saving power. The use of LEDs in the backlight module as the light source replaces the traditional cold cathode fluorescent lamp (CCFL), which not only has the advantages of lightness, power saving, and volume In addition to the advantages of small size, long life, low voltage, and fast start-up, it also has the concept of environmental protection. For notebook computers, depending on the processor and size, the power consumption of the LCD panel accounts for about one-third of the whole machine. Due to the low power consumption of the LED, the current use of the LED backlight NB can extend its use time by more than 1.5 hours; The thickness of the light guide plate with LED can be reduced from 2mm to 0.6mm (13.3-inch product), the thickness of the screen can be reduced, and the weight of the whole machine will also be reduced; and currently each CCFL contains about 2mg of mercury, using LED as the light source Can reduce the use of mercury. If RGB is mixed into white light, it can provide better color saturation, and the color of the TV screen will be more vivid. The LED can be dynamically controlled by the area, turning off when the screen is black in some areas to improve the contrast between light and dark, and at the same time it can save power. The LED has a fast response speed. Using RGB three-color LEDs with fast-response liquid crystals can use the Color Sequituonal method to omit the use of color filters. The luminous efficiency of LED is only 20-40lm/W, which is not as good as the 80lm/W of CCFL. At the same time, the high cost will be the biggest weakness of the LED backlight module. The unit price of a CCFL and a high-brightness LED is around US$1.5, but the number of LEDs used far exceeds that of CCFL. In addition, the poor heat dissipation of LEDs, the use of large-size TVs need to add heat dissipation substrates, will be another item, and the attenuation speed of each LED color is different, long-term use will cause uneven color.
