A luminance inspector used for in-line backlight module quality assurance

In this paper, we propose a luminance inspector which uses a CCD camera and neural network models to inspect multiple backlight modules at once. The proposed inspector can display the results at predetermined checked points in real time which is important for in-line quality check. The proposed inspector is more efficient compared to the traditional inspector which examines checked points one by one. Experiments show that the proposed inspector yields satisfactory results.
