Abstract
LED (Light Emitting Diode) display as a new display device, has been the development of rapid, widely used in highway, urban trunk roads, securities, stadiums, arena and other public occasions. LED importance because of widespread and rapid development, with its own advantages as inseparable. To sum up these advantages are: high brightness, low voltage, small power consumption, small size, long life, impact resistance and stable performance. LED very bright prospects for the development, the current is moving in a higher brightness, higher weather resistance, and higher luminous density, higher luminous uniformity, reliability, full color and direction.
LED dot matrix display system in order to STC89S54 single-chip microcomputer as the core of intelligent design can be updated display LED dot matrix; can display real-time date and time face significant lunar and solar calendar of festivals, celebrating the pop-up A message from a certain holiday, holiday in the range of 2000-2099.
LED dot matrix display system, most functional software to achieve, so that the circuit is simple and greatly improved system stability. The system not only achieved the success of the basic functions required to play the part has been fully realized, but also has some innovative features.
