History of display technology

Electrically operated display devices have developed from electromechanical systems for display of text, up to all-electronic devices capable of full-motion 3D color graphic displays. Electromagnetic devices, using a solenoid coil to control a visible flag or flap, were the earliest type, and were used for text displays such as stock market prices and arrival/departure display times. The cathode ray tube was the workhorse of text and video display technology for several decades until being displaced by plasma, liquid crystal (LCD) and solid-state devices such as LEDs and OLEDs. With the advent of microprocessors and microelectronic devices, many more individual picture elements ("pixels") could be incorporated into one display device, allowing graphic displays and video.

History

One of the earliest electronic displays is the [1] CRTs were the single most popular display technology used in television sets and computer monitors for over half a century; it was not until the 2000s that LCDs began to gradually replace them.

A derivative of CRTs were [2]

Cathode ray tube

Monochrome CRT

1922 Monochrome cathode ray tube:

Dual trace, showing different time bases on each trace.

Color CRT

Direct-View Bistable Storage Tube

1968[2] The Direct-View Bistable Storage Tube CRT retains static information displayed upon it, written using a steerable electron beam that can be turned off. In principle the DVBST is similar to an Etch-a-Sketch, and was used in vector displays of early computers and in oscilloscopes.

Flip-flap/disc display

1957 Split-flap display:

Flip-Dot-Display

Monochrome plasma display

1964 Monochrome plasma display:

Plasma displays were first used in PLATO computer terminals. This PLATO V model illustrates the display's monochromatic orange glow as seen in 1988.

Light-emitting diode

1968 Light-emitting diode:

LED destination displays on buses, one with a colored route number.

Eggcrate display

1968 Eggcrate display

Vacuum fluorescent display

1967 Vacuum fluorescent display as used in consumer electronics.

Vacuum fluorescent display used in a videocassette recorder.
VFD raster display

Twisted nematic field effect LCD

1971 Twisted nematic field effect LCD [3] [4]

Super-twisted nematic LCD

1984 Super-twisted nematic display (STN LCD) to improve passive-matrix LCDs, allowing for the first time higher resolution panels with 540x270 pixels.

Prototype Brown Boveri STN LCD with 540x270 pixels

Each ring makes one digit of the calculator's display. The numbers from zero to nine are in each ring. To display a numeral, the calculator briefly flashes a light behind it.
