How They Came To Be

Today's monitors have a long history, spanning from the first personal computer to today's big-screen LCD. Along the way, innovations enabled growth of PCs as well as industries, such as computer gaming. Current LCD computer monitors now outnumber the original CRT screen. Screens now displaying millions of colors for complex graphics began with just two for basic text.
The video display terminal, or VDT, marked the early days of computer monitors. These VDTs included a screen and attached keyboard linked to a larger computer by a serial connection. Because VDTs required a connection to a larger computer, they were often referred to as "dumb terminals." Dumb terminals displayed text only in two colours, usually black and green. The Apple II and first game machines began using a television CRT.

LCD's (otherwise known as Liquid Crystal Displays)

Although the CRT dominated computer monitor sales since 1980, the rise of Liquid Crystal Displays (LCDs) has nearly eclipsed the venerable CRT. More than 20 years after RCA first experimented with LCDs in 1968, the price of new monitors has fallen while size increased. First developed for calculators and other small device displays, LCDs now measure 21-inches or more. In 1990 the popularity of LCD computer displays began. By 1997 LCD monitors were competing with CRTs
