What are the classifications of watch displays
LED display type. When you need to check the time, press the button and small red numbers will appear on the surface. After showing for one or two seconds, these numbers will disappear again. In addition to displaying the hour and minute numbers, most of the light-emitting diode electronic devices can also display the date and second. But it does not appear at the same time as the hour and minute numbers. If a different number is displayed, a different button must be pressed. The number of seconds displayed can continue to be presented continuously.
Liquid crystal display type. Liquid crystal display devices utilize the optical anisotropy characteristics of liquid crystals. Under the action of the electric field, the external illumination is modulated to realize the display. The liquid crystal display device is a thin device with a thickness of only a few millimeters. The working voltage is low, only a few volts, and it is directly driven by the cmos circuit. Miniaturization of electronic circuits.
Quartz analog type. The micro-motor controlled by the transistor in the watch drives the hour, minute, and second hands on the surface. Quartz Electronic Yuan’s travel time is very accurate, and the error of speed within a month is within a few seconds. The price of the electronic watch itself is also declining with the advancement of technology. In the end it may drop to such a degree.
