Clock

Abstract

The invention provides a clock. The clock comprises a graduated disc, a clock signal generator, a time counter, a data selector and a decoding driver, wherein the graduated disc comprises a graduated surface and twelve groups of light-emitting diodes (LEDs); the twelve groups of LEDs are distributed on the graduated surface and arranged at equal intervals to form an hour graduated ring; each group of LEDs comprise sixty LEDs which are arranged at equal intervals to form a minute graduated ring; and the clock signal generator, the time counter, the data selector and the decoding driver are used for generating a time driving signal for selectively driving the twelve groups of LEDs to emit light so as to indicate the current moment. The twelve groups of LEDs which are arranged by simulating the graduated disc of a pointer clock are used for indicating the current moment, so the clock has high indicating property; and the LEDs do not generate sound when emitting the light to indicate timeand silently indicate the 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...
