LED Watch Quartz electronic watches, the battery energy to the quartz oscillator time base, to integrated circuits as the core pointer or numbers to show by the time the structure. Quartz electronic http://www.sourcinggate.com/led-watch-c-477.html watches may be referred to as the quartz form, which includes quartz watches and quartz clocks. Quartz tables are Pointer, digital and dual-explicit 3. From the composition, Pointer and Pointer quartz quartz  , digital watches and digital quartz clock quartz is the same, but Analogue quartz watches and digital quartz clock table is not the same. ① Analog and digital quartz watches, a basic component (see Figure). Analog quartz analog watch quartz watches called. Pointer with the traditional mechanical watch list disk. Necessary, can be made into 3-pin or two pins to attach a single calendar or a double calendar. Is a popular quartz watches. Digital quartz watches with digital display but not the time pointer. Show two ways. One is the light-emitting diode display (the LED), due to large power  LED Watchconsumption, is no longer used; the other is the liquid crystal display (referred to as LCD), for now most of the digital quartz watch with. It consumes a small, simple structure and low cost. But the LCD is a passive light, in the dark can be seen lighting the table number, while small angle LCD. Dual display combines these two kinds of quartz watches, quartz watches advantages. It is both a pointer to pointer quartz watches, but also figures featured. Analog and digital quartz watches have in common is: energy is used batteries, used silver oxide batteries or mercury batteries; time basis and are based on quartz oscillator, frequency usually 32768Hz. In order to get the time from the basic unit of frequency ─ ─ seconds, minutes and hours, using the large-scale complementary metal oxide semiconductor integrated circuits, CMOS integrated circuit that is. The biggest difference between the two watches is: Analog quartz watch, in order to turn electrical signals into a pointer to indicate the time, used as a transducer micro stepping motor and gear drive system; digital quartz watches in the digital liquid crystal display devices, and in the circuit with the corresponding control circuit and step-up circuit.LED Watch
