As the world is fast revolving, technology also becomes more advanced. Providing more interesting and fascinating products, one of these are the programmable LED signs. Light-emitting diode also referred to as LED is a lead semiconductor light source. In early days, LED were usually used as indicator lamps for electronic devices which replaced the use of small incandescent bulbs. They were soon enclosed into numeric readouts in the form of seven-segment displays, which are frequently seen in digital clocks.
Current progress of the use of LED allows them to be utilized in the environment and task lighting. As LED resources technology grew more advanced, light production rose, while maintaining efficiency, effectiveness and reliability at acceptable point. The discovery and expansion of the high-power white-light LED directed to the use for illumination, and slowly replaced the use of incandescent and fluorescent lighting. LED have many uses over incandescent light sources such that they use less energy, provide longer life span, have developed physical robustness, smaller size, and are faster switching. However, for every advantage come disadvantages. The use of LED for room lighting is powerful enough that it becomes comparatively expensive, and needs to entail an extra and accurate current and heat management than those compact fluorescent lamp sources of similar output. Most LED for programmable signs were made in the very usual 5 mm T1 3/4 and 3 mm T1 packages, however with the increasing power output, it has grown increasingly essential to shack excess heat to maintain reliability, so more complex and multifaceted packages have been adapted for efficient heat dissipation.

But even though with these disadvantages, LED are still in demand and are a great help to many companies. Today, LED are used for application as assorted and various as aviation lighting, automotive headlamps, advertising, general lighting, traffic signals, and camera flashes. LED are most commonly used in advertising industry wherein businessman needs these as displays outside their stores. This is a very good example is programmable LED sign for outdoor message boards. These are a flat panel display which uses a lead semiconductor light source for it to function effectively. These programmable LED signs have permitted new text, video displays, and sensors to be developed, while their high switching rates are also helpful in advanced communications technology. Since these programmable LED signs use advanced technology, it provides great features such as "message movements" and "append modes", and include programming software which will be compatible to PCs, and laptops.
