Clock

Abstract

A light emitting diode (LED) base clock includes a clock face and twelve groups of LEDs. The twelve groups of LEDs are arranged as an hourly indicator. Each group of LEDs are arranged as a minutely indicator. The clock further comprising a time signal generator configured for generating time signals and selectively drive corresponding LEDs to light using the time signals to display the time and keep time.

Description

technical field [0001] The present invention relates to a clock. Background technique [0002] Existing clocks can be roughly divided into two types: pointer type and digital type. An analog clock generally indicates time by a pointer moving on a dial, which is good in indication, clear and easy to read. However, due to the relatively loud movement of the hands, the analog clock has the disadvantage of high noise. Digital clocks generally use black and white display panels such as LCD panels to display Arabic numerals to indicate time, and there is no noise problem. However, the display effect of the black and white display panel is not ideal, the contrast ratio is low, the viewing angle is limited, and the indication is poor. In addition, in order to reduce power consumption, digital clocks generally use smaller-sized black and white display panels as much as possible, which further affects their indication. Contents of the invention [0003] In view of this, it is ne...
