LED backlight has gradually become the mainstream development trend

Compared with traditional CCFL (cold cathode tube) backlights, LEDs have advantages such as low power consumption, low heat generation, and high brightness. Domestic professional LCD splicing factory Emperor Ai Di analysis said that as the concept of low-carbon energy continues to infiltrate and highlight the application of continuous stimulation, the future application of LED backlight in the field of LCD splicing will become more and more widely, has become the mainstream development trend.

In general, the brightness of a CCFL lamp backlit LCD screen is 100~200cd/m2, and the brightness of two CCFL lamp backlit LCD screens is 200~300cd/m2. The more lamps, the brightness increases. However, by increasing the number of tubes to increase the brightness of the LCD screen, it also increases the power consumption of the LCD screen. LED backlight refers to the LED (light emitting diode) as the backlight of the LCD screen. Ordinary LED lamp backlight LCD screen brightness can reach 350cd/m2 or more, increase the LED lamp power, brightness can meet the visual requirements of sunlight brightness - 600cd/m2 above the ultra-high brightness, this can be visible in the sun LCD Screen commonly known as highlight LCD screen.

The power consumption of the LED lamp backlighting LCD screen is only a few watts, which increases the LED lamp power, increases the brightness, and does not increase the power consumption. The power consumption of the ordinary CCFL lamp backlit LCD screen is more than 30W. The number of lamps increases, the brightness increases, and the power consumption also increases exponentially.

At present, most of the LCD splicing screens use LED backlights, and the brightness can reach 800cd/m2, which can better display the pictures on the splicing wall, minimizing the viewer's visual blind spot and visual splitting, and the performance is stable. Small stitching seams are ideal for monitoring environmental applications. The LCD spliced ​​large screen integrates seamlessly into any existing control center and supports multiple signal input ports and arbitrary content.

LCD splicing screen adopts LED backlight source to make the picture more clear, the contrast is increased, the service life is also increased, the color saturation is good, the advantages of ultra-thin appearance, energy saving and environmental protection make the LCD splicing screen win the favor of consumers in the market.
