LCD Driving Method Back Light Unit The back light unit is one of the core components of an LCD, providing the light required to illuminate the display screen. Unlike OLED, which is a self-emissive technology, LCDs do not generate their own light and therefore require an external light source - the backlight. As the light from the backlight passes through the liquid crystals and the color filter, the color of each pixel is determined. When the liquid crystals completely block the light to each subpixel, black is displayed: when they fully allow the light white is produced. Structure of an LCD Backlight The structure of a back light unit consists of multiple layers. It includes a lamp that emits light, a reflection sheet that reduces optical loss, a lightguide plate that distributes light evenly, a diffusion sheet that spreads the light uniformly, and a set of prism sheets that enhance optical efficiency. Common light sources used in backlights include CCFLs and LEDs. In recent years, LEDs have become the primary choice, as they enable thinner designs and deliver higher brightness.
