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, projectors ...
In 1988, Sharp demonstrated a 14-inch, active-matrix, full-color, full-motion TFT-LCD. This led to Japan launching an LCD industry, which developed large-size LCDs, including TFT computer monitors and LCD televisions. [55] Epson developed the 3LCD projection technology in the 1980s, and licensed it for use in projectors in 1988. [56]
Detail of a TFT display showing whole screen persistence artifacts TFT display showing persistence artifacts Image persistence on a BenQ GW2765HT IPS LCD monitor. Image persistence, or image retention, is a phenomenon in LCD and plasma displays where unwanted visual information is shown which corresponds to a previous state of the display.
Having supplanted passive-matrix LCDs in general use, in common vernacular, an active-matrix LCD is also simply referred to as a LCD. As of 2025, the term "AMLCD" is uncommon as a matter of technical jargon ; instead, due to their ubiquity, different types of active-matrix liquid crystal displays are usually specified — TFT LCD , IPS LCD ...
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]
The first commercial TFT-based AM LCD product was the 2.1-inch Epson [41] [42] [43] ET-10 [37] (Epson Elf), the first color LCD pocket TV, released in 1984. [44] In 1986, a Hitachi research team led by Akio Mimura demonstrated a low-temperature polycrystalline silicon (LTPS) process for fabricating n-channel TFTs on a silicon-on-insulator (SOI ...
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). [2] Under bright illumination (e.g. when exposed to daylight) the display acts mainly as a reflective display with the contrast being constant with ...
Directly behind the scintillator layer is an amorphous silicon detector array manufactured using a process very similar to that used to make LCD televisions and computer monitors. Like a TFT-LCD display, millions of roughly 0.2 mm pixels each containing a thin-film transistor form a grid patterned in amorphous silicon on the glass substrate. [1]
