Detection and Analysis of LED Display System in Large Stadiums

Abstract

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.

“…2) Constant current drive Using the basic principle of constant current low-pass drive can effectively overcome the serious impact of the dispersion of external devices [22][23]. Since the constant current output circuit of the new transistor has the characteristics of oriented constant current drive, it can be considered to use the new transistor constant current drive device LED.…”
