LCD monitor and LCD TV manufacturers want to solve the problem about scaler board and PCB assembly test solution at present. It's very difficult to analyze large data by instruments. Because the scaler board output LVDS belongs serial signals. The test solution of scaler board PCBA use LCD panel to check image quality.
HXT provides the scaler board automation test solution and use high speed garbbing card and IMAQ to test.
LCD Scaler Board Test System
1:LCD scaler board (imaging and data garbbing)
The LCD scaler board can't automation for testing because the scaler board data acquisition.LVDS is not easy to external instruments such as logic analysis or restore the original image signal by oscilloscope.
The high speed imaging grabbing card of NI provides high speed image bandwidth and the same signal of LDVS. So,the best choice of equipment.
2:To analyze the value of test imaging
The image of LCD scaler board is captured to the computer, how to analyze the captured image data and how to distinguish product characteristic is a major challenge.
NI IMAQ image library has the function of visual testing analysis and saving the time of test system.
3:Check defect imaging
The abnormal image of scaler board is appeared in the different location, shapes and sizes in different test pattern. Algorithm and artificial intelligence to check abnormal image because the test program can't distinguish it.
