What type of backlighting is commonly used in LCD displays for improved color reproduction ?
Fluorescent backlighting
An LCD panel does not emit light by itself; the liquid-crystal cells only modulate light coming from a backlight behind them.
For many years the standard LCD backlight was the cold-cathode fluorescent lamp (CCFL). Its phosphor emission covers the red, green and blue parts of the spectrum well, giving the colour filters a broad white light to work with and thus good colour reproduction.
Incandescent lamps are inefficient, hot and yellowish, lasers are not a common LCD backlight, and OLED is a self-emissive display technology that needs no backlight at all.
Hence, the backlighting commonly used in LCD displays is Fluorescent backlighting.
