发明名称 Electronic timepiece with negative resistance light emitting elements
摘要 A time calculation ring counter is made of a plurality of negative resistance light emitting elements, which provide display of current time information. In a preferred form, a plurality of GCR's (gallium arsenide gate controlled rectifiers) or a plurality of GND's (gallium arsenide negative resistance light emitting diodes) are aligned in a circular fashion on a display panel of an electronic timepiece. The GCR's or GND's function to either calculate the time information or indicate the time information.
