Solar Powered Scrolling led Display Board for Public Utility Places

This work introduces a development of scrolling LED notice board with self-generating power from built in solar panel for its working. The main advantage of the project is to get a major reduction in paper consumption and manpower. The messages can also be passed immediately without any delay. Scrolling LED display is used as it is low power and low cost. The led Display System is aimed at the colleges and universities for displaying day-to-day information continuously or at regular intervals during the working hours.

Detection and Analysis of LED Display System in Large Stadiums

As the mainstream products of flat panel display, LED screen is becoming more and more popular, which has been widely used in the display system of large gymnasium. The detection of LED display system in large stadium is analyzed. Based on the large LED display in Jingzhou stadium, the qualification of LED display system after installation is tested. A scanning line seed filling algorithm is proposed and used to collect the gray value in the connected domain of the lamp and obtain the average gray value of the light point, so that the LED display system of the large gymnasium is detected. The experimental results show that a reasonable LED display and adjustment scheme can ensure the installation of LED display system in large gymnasium in line with the requirements of the national standard.
