Digital wall clocks
Earlier this my review on watches that you can hang on, did I mention that there are also digital wall clocks. The digital word means “numeric” and indicates the type of watches that do not serve the hands because the time is indicated in figures. These figures are produced by the movement of liquid crystals in seven segments. With the passage of time, the liquid crystals are positioned to form the numbers from 0 to 9, drawing precisely the time on an LCD display.
Not so very long ago, instead of liquid crystals were used by LED, however in the long run the energy consumption of these watches was quite high. Even today the digital clocks are powered electrically, because batteries are needed to make them work.
However, the power consumption of LCD clocks is much lower compared to LEDs. Even just a very small stack to allow these watches to continue operating for several years in a row.
Mechanism of these clocks
Most digital clocks is based on a quartz mechanism. Quartz is a common mineral in nature, so it’s not very expensive, which has several interesting properties. Among these, it has been discovered that if you cut a quartz crystal in a very specific way and then smites, this crystal vibrates at a certain frequency adjust.
This charming property is what led him to produce the first quartz watches for if a quartz crystal has the right size, you can do so that the frequency of vibrations corresponds to very specific time intervals, such as the second. Also, in the percussion of quartz crystals will be initiated and made possible by an electrical impulse, sent from the battery.
Scan time by the quartz crystal is then connected to a mechanism that allows us to see what time it is. In the case of digital clocks, as I already explained, the time is expressed in digits displayed on a display. Though the mechanics are also used in quartz clocks with hands.
The accuracy of these watches is far superior to that of mechanical watches, to the point that the mechanism is based on quartz crystals to calculate time is used very much even in time, where time is measured in milliseconds. Today, moreover, the technologies and materials used to produce this kind of watches are always lower cost, so you really can buy a quartz wall clock with a digital display at affordable rates.
