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 storage tubes , which had the ability to retain information displayed on them, unlike standard CRTs which need to be refreshed ...
Nick Holonyak Jr. (/ h ʌ l ɒ n j æ k / huh-LON-yak; November 3, 1928 – September 18, 2022) was an American engineer and educator.He is noted particularly for his 1962 invention and first demonstration of a semiconductor laser diode that emitted visible light.
A flat-panel display (FPD) computer monitor A cathode-ray tube (CRT) computer monitor A computer monitor is an output device that displays information in pictorial or textual form. A discrete monitor comprises a visual display , support electronics, power supply, housing , electrical connectors , and external user controls.
Green electroluminescence from a point contact on a crystal of SiC recreates Round's original experiment from 1907. Close-up of a 1 watt red power led. The first Light-Emitting Diode was created in 1927 by Russian inventor Oleg Losev, [1] and used silicon carbide as a semiconductor.

To save the cost of a dedicated monitor, the home computer would often connect through an RF modulator to the family TV set, which served as both video display and sound system. [17] The rise of the home computer also led to a fundamental shift during the early 1980s in where and how computers were purchased.
It was the first alphanumeric LED display, and was a revolution in digital display technology, replacing the Nixie tube for numeric displays and becoming the basis for later LED displays. [24] In 1977, James P Mitchell prototyped and later demonstrated what was perhaps the earliest monochromatic flat-panel LED television display.
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals.
