What is light wave watch and electronic paper watch?
Light wave watch
The solar-powered radio wave watch uses the radio wave receiver and antenna built into the watch. Receive the “standard time” radio waves sent by the transmission tower to obtain data such as time and calendar. Automatically correct the time and date of the watch. The standard time signal uses the theory of high-precision cesium atomic watches, with an error of one second in 100,000 years. Radio-controlled watches all use light kinetic energy technology and use any visible light source as energy drive. As long as there is light, there is energy, and as long as the radio waves can be received, there will never be errors.
Electronic paper watch
An electronic paper watch is a watch equipped with an electronic paper display inside. It can display the time, day of the week, and date. The way to realize electronic paper technology mainly includes cholesterol liquid crystal display technology. And electrophoresis display technology and electrowetting display technology. The electronic watch paper used in electronic paper watches mainly adopts electrophoretic display technology. The display brightness and contrast of the electronic paper watch are high. There is no need to use backlighting to improve readability. The electronic paper display used in the electronic paper watch has a simple hardware structure and the thickness can reach about 1mm. It is a new force in the watch army.
