The LCD panel is powered by LCD drivers that are carefully matched up with the edge of the LCD panel at the factory level. The drivers may be installed using several methods, the most common of which are COG (Chip-On-Glass) and TAB ( Tape-automated bonding ) These same principles apply also for smartphone screens that are much smaller than TV ...
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 ...
The operation of TN, VA and IPS-LCDs can be summarized as follows: a well aligned LC configuration is deformed by an applied electric field, this deformation changes the orientation of the local LC optical axis with respect to the direction of light propagation through the LC layer,
An active-matrix liquid-crystal display (AMLCD) is a type of flat-panel display used in high-resolution TVs, computer monitors, notebook computers, tablet computers and smartphones with an LCD screen, due to low weight, very good image quality, wide color gamut and fast response time.
Liquid crystal display (LCD) An LCD is a display technology employing the use of liquid crystals to form images. Thin-film transistor (TFT) A TFT refers to the thin layer of transistors used with an LCD. LED-backlit LCD An LCD display which uses LEDs as a backlight. Prior to the use of LED based backlighting, Cold Cathode Fluorescent (CCFL ...
An LCD TV. A liquid-crystal-display television (LCD TV) is a television set that uses a liquid-crystal display to produce images. It is by far the most widely produced and sold type of television display.
Major technologies are CRT, LCD and its derivatives (Quantum dot display, LED backlit LCD, WLCD, OLCD), Plasma, and OLED and its derivatives (Transparent OLED, PMOLED, AMOLED). An emerging technology is Micro LED. Cancelled and now obsolete technologies are SED and FED.
The image shows a rotation of the director about 180° in a cholesteric phase. The corresponding distance is the half-pitch, p/2. A cholesteric liquid-crystal display (ChLCD) is a display containing a liquid crystal with a helical structure and which is therefore chiral.
