【Abstract】 A way to capture the data for LED display screen was introduced. We can capture the analog signals from display adapter to achieve synchronous display with computer, as well as adjust the position and size of displaying window by means of making special software, which is more flexible and more compatible with out using special display adapter. Therefore, It is very easy to achieve and have practical value.更多还原
