Solid State LED Display Device.
Abstract
A visual display system constructed to provide increased resolution of a digital signal representing a measured analog value is described. An analog signal is converted to a digital number represented by a group of most significant bits and lesser significant bits. Each group of digits is stored in a digital storage circuit with the group of most significant bits additionally being stored in a preset counting circuit and increased in value by a logical 1. The outputs of the storage and counting circuits holding the group of most significant bits are then coupled to energize elements of a visual display for a time proportional to the digital number represented by the group of lesser significant bits. The magnitude of the analog signal can then be determined by observing the position and relative length of time that any of two elements of the display are energized over a sampling period.
