Flat-panel displays are thin panels of glass or plastic used for electronically displaying text, images, or video. Liquid crystal displays (LCD), OLED (organic light emitting diode) and microLED displays are not quite the same; since 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 ...

The Chumby One [24] Freescale iMX233 454 MHz ARM926EJ-S processor; 64 MB DDR SDRAM
A thin-film-transistor liquid-crystal display (TFT LCD) is a type of liquid-crystal display that uses thin-film-transistor technology to improve image qualities such as addressability and contrast. [1] 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 ...
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. [63] Epson developed the 3LCD projection technology in the 1980s, and licensed it for use in projectors in 1988. [64]
A 16×2-character dot-matrix display, where each character is made from a grid of 5×7 dots. A dot-matrix display is a low-cost electronic digital display device that displays information on machines such as clocks, watches, calculators, and many other devices requiring a simple alphanumeric (and/or graphic) display device of limited resolution.
176×220 pixel TFT LCD The Motorola RAZR V3 , popularly called simply the Razr (pronounced / ˈ r eɪ z ər / like "razor"), is a clamshell style cell phone developed by Motorola and initially released in November 2004, the first device using the RAZR moniker.
Display size. On 2D displays, such as computer monitors and TVs, display size or viewable image size (VIS) refers to the physical size of the area where pictures and videos are displayed. The size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners, typically measured in inches.
Backlight. A backlight is a form of illumination used in liquid-crystal displays (LCDs) that provides illumination from the back or side of a display panel. LCDs do not produce light by themselves, so they need illumination (ambient light or a special light source) to produce a visible image. Backlights are often used in smartphones, computer ...
