The digital electronic watch mainly uses two kinds of display devices: LED (Light Emitting Diode display) and LCD (Liuid Cry.stal Display). The LCD electronic watch uses GaAs/p light-emitting diodes as a display. This type of display consumes a lot of power, and the surface is not continuously whirling, but when you need to look at it, you can press the button to see the displayed numbers. The LCD electronic watch uses a nematic liquid crystal display as a display.

Digital quartz watch integrated circuits should pay attention to the problems. The full name of digital quartz watch integration is complementary metal monoxide-semiconductor integrated circuit (Complementary Metal Oxide Semiconductor) abbreviated as CMOS. It controls all functions of the electronic watch. The chip area of the integrated circuit product is about 10 square millimeters. It is connected to the lead of the circuit board by spot welding with gold wire or aluminum wire, and then protected by black sealant.
