This can be considered a disadvantage compared to CCFL-backlit LCDs however, if the display allows for the local dimming algorithm to be disabled via software, doing so will remove any blooming at the cost of negating some of the display's contrast-enhancing capabilities. Some LED-backlit LCDs use local dimming zones to increase contrast between bright and dim areas of the display, but this can result in a "blooming" or "halo" effect on dark pixels in or adjacent to an illuminated zone. Unlike OLED and microLED displays, LCDs cannot achieve true blacks for pixels which are illuminated by the backlight. Typically 20–30% lower power consumption and longer lifespan.Significantly lighter and cooler, as much as half the total chassis and system weight of a comparable CCFL. Very slim (some screens are less than 0.5 inches (13 mm) thin in edge-lit panels).Wider color gamut (with RGB-LED or QDEF) and dimming range.When compared with earlier CCFL backlights, using LEDs for backlighting offers: Comparison with CCFL-backlit LCDs Advantages While not an LED display, a television using such a combination of an LED backlight with an LCD panel is advertised as an LED TV by some manufacturers and suppliers. LED-backlit displays use the same TFT LCD ( thin-film-transistor liquid-crystal display) technologies as CCFL-backlit LCDs, but offer a variety of advantages over them. For true LED displays, see LED display.Īn Apple iPod Touch disassembled to show the array of white-edge LEDs powered on with the deviceĪn LED-backlit LCD is a liquid-crystal display that uses LEDs for backlighting instead of traditional cold cathode fluorescent (CCFL) backlighting.
