CCFL backlights are used on larger displays such as computer monitors, and are typically white in color; these also require the use of an inverter and diffuser. Incandescent backlighting was used by early LCD panels to achieve high brightness, [8] [9] but the limited life and excess heat produced by incandescent bulbs were severe limitations ...
LCD panels also commonly have a defect known as clouding, dirty screen effect, or, less commonly, mura, which involves uneven patches of luminance on the panel. It is most visible in dark or black areas of displayed scenes. [143] As of 2010, most premium branded computer LCD panel manufacturers specify their products as having zero defects.
This list includes LCD, OLED and microLED display manufacturers. LCD uses a liquid crystal that reacts to an electric current blocking light or allowing it to pass through the panel, whereas OLED/microLED displays consist of electroluminescent organic/inorganic materials that generate light when a current is passed through the material.
A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven (i.e. with segments directly connected to electronics outside the LCD) LCDs with a few segments. TFT LCDs are used in television sets , computer monitors , mobile phones , video game systems, personal digital assistants , navigation systems ...
A Pixel Qi screen installed in an OLPC XO laptop operating in transmissive mode. The screen is in color mode and is retro-illuminated. A transflective liquid-crystal display [1] is a liquid-crystal display (LCD) with an optical layer that reflects and transmits light (transflective is a portmanteau of transmissive and reflective).

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.
The LCD grid can mask effects of spatial and grayscale quantization, creating the illusion of higher image quality. [52] Is the cheapest display technology currently produced, with some entry-level models selling for less than $100. Screen-door effects are more noticeable than LCD when up close, or on larger sizes. [53]
