A watch that displays time by using digits (numbers) instead of hands/markers and a dial [analog display].

Includes display technologies such as LCD, Plasma and LED. There are other emerging digital display technologies such as OLED a cost effective.

As opposed to an analogue display, a digital display shows the time in numbers. Most often used with LCD displays in the case of a quartz watch, during the 1960's there were many mechanical digitals with rotating discs instead of hands. Cut outs in the dial would show the correct time. The first quartz digital watches came onto the market in the early/mid 1970s; for example the Pulsar Time Computer.

Shows the time with a liquid crystal display.

Display that indicates values, such as rpm, mph, voltage in an electronic LED readout format rather than a movable needle. Digital displays are harder to read at a quick glance.

A technique in which digitized trace information, stored in memory, is displayed on the screen. The displayed trace is a series of points designed to present a continuous looking trace. While the default number of display points varies between different models, most modern spectrum analyzers allow the user to choose the desired resolution by controlling the number of points displayed. The display is refreshed (rewritten from data in memory) at a flicker-free rate; the data in memory is updated at the sweep rate. Nearly all modern spectrum analyzers have digital flat panel LCD displays, rather than CRT-based analog displays that were used in earlier analyzers.
