High-resolution color displays, such as modern LCD computer monitors and televisions, use an active-matrix structure. A matrix of thin-film transistors (TFTs) is added to the electrodes in contact with the LC layer. Each pixel has its own dedicated transistor, allowing each column line to access one pixel. When a row line is selected, all of ...
Overall, color reproduction and linearity on TN panels is poor. Shortcomings in display color gamut (often referred to as a percentage of the NTSC 1953 color gamut) are also due to backlighting technology. It is common for older displays to range from 10% to 26% of the NTSC color gamut, whereas other kind of displays, utilizing more complicated ...
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).

The LCD grid can mask effects of spatial and grayscale quantization, creating the illusion of higher image quality. [57] 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. [58]
LCD TVs are thin and light, but have some disadvantages compared to other display types such as high power consumption, poorer contrast ratio, and inferior color gamut. LCD TVs rose in popularity in the early years of the 21st century, and exceeded sales of cathode-ray-tube televisions worldwide from late 2007 on. [ 1 ]
This is a milestone for implementing large-screen LCDs having acceptable visual performance for flat-panel computer monitors and television screens. In 1996, Samsung developed the optical patterning technique that enables multi-domain LCD. Multi-domain and in-plane switching subsequently remain the dominant LCD designs through 2006. [10]
