LED backlights have revolutionised the way we view screens, offering significant advantages over older backlighting technologies. They have become the dominant technology in various applications, from small handheld devices to large television displays.
LED backlights are a type of lighting system that uses light-emitting diodes (LEDs) to illuminate liquid crystal displays (LCDs). Unlike traditional cold cathode fluorescent lamps (CCFLs), LEDs are much smaller, more energy-efficient, and offer greater control over brightness and colour.
LED backlights work by emitting light from an array of LEDs placed behind the LCD panel. This light passes through the liquid crystals, which act as tiny shutters, controlling the amount of light that reaches each pixel. By selectively blocking or allowing light to pass through, the LCD creates an image on the screen.
LED backlights offer several advantages over other backlighting technology:
- Energy Efficiency: LEDs are significantly more energy-efficient than CCFLs, resulting in lower power consumption and longer battery life for portable devices.
- Longer Lifespan: LEDs have a much longer lifespan than CCFLs, reducing the need for replacements.
- Improved Colour Accuracy: LEDs offer a wider colour gamut and more accurate colour reproduction compared to CCFLs.
- Better Contrast: LED backlighting, especially full-array with local dimming, can achieve higher contrast ratios and deeper black levels.
Nuline specialises in custom-developed LED backlight modules for the auto industry. These modules are manufactured to deliver uniform light intensity over a wide area of display using special light distribution technology. LEDs are bin-sorted for the same light wavelength to deliver perfectly matched colour between modules.
