A dot-matrix display is a display device used to display information on machines, clocks, railway departure indicators and many other devices requiring a simple display device of limited resolution. The display consists of a dot matrix of lights or mechanical indicators arranged in a rectangular configuration (other shapes are also possible, although not common) such that by switching on or off selected lights, text or graphics can be displayed. A dot matrix controller converts instructions from a processor into signals which turns on or off lights in the matrix so that the required display is produced. ==Usual resolutions== Common sizes of dot matrix displays: *128×16 (Two lined) *128×32 (Four lined) *128×64 (Eight lined) Other sizes include: *92×31 (Four or three lined) 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「Dot-matrix display」の詳細全文を読む スポンサード リンク
