An LED-backlit LCD is a liquid-crystal display that uses LEDs for backlighting instead of traditional cold cathode fluorescent (CCFL) backlighting. [1] 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.
OLED displays use 40% of the power of an LCD displaying an image that is primarily black as they lack the need for a backlight, [35] while OLED can use more than three times as much power to display a mostly white image compared to an LCD. [36] Environmental influences
This chart shows the most common display resolutions, with the color of each resolution type indicating the display ratio (e.g., red indicates a 4:3 ratio).
Transflective LCDs combine the features of a backlit transmissive display and a reflective display. The common implementations of LCD backlight technology are: 18 parallel CCFLs as backlight for a 42-inch (106 cm) LCD TV. WLED array: The LCD panel is lit by a full array of white LEDs placed behind a diffuser behind the panel.
