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 cathode ray tube (CRT), which was made commercial in 1922. The CRT consists of an electron gun that forms images by firing electrons onto a phosphor-coated screen. The earliest CRTs were monochrome and were used primarily in oscilloscopes and black and white televisions. The first commercial colour CRT was produced in 1954.〔(– earlytelevision.org – Picture Tubes, 15GP22 Color CRT )〕 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 periodically. In 1968, Tektronix introduced the Direct-View Bistable Storage Tube, which went on to be widely used in oscilloscopes and computer terminals.〔(medical-answers.org – Tektronix 4014 )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「History of display technology」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
