Liquid Crystal Matrix Displays
Electronic techniques of displaying information are becoming widely used. The applications of these displays range from the display of simple numeric information — as in a watch or digital voltmeter — to the display of radar or television information. Most of these displays emit radiation and thus consume considerable amounts of power when they are bright enough to be seen in high-ambient lighting conditions. The alternative display is one that does not compete with incident radiation but modulates it — just as a printed page or blackboard writing does. A display of this form will be visible in the brightest lighting conditions but need not consume large amounts of power. They are known as “passive” or “subtractive” displays and it is in this area that liquid crystals show considerable promise.
