AUTOMATIC DYNAMIC PIXEL MAP CORRECTION AND DRIVE SIGNAL CALIBRATION

摘要

To determine the pixel positions of a flat panel display, signals are applied to the gate lines and the data lines of the flat panel display without exciting the pixels. The gate lines and data lines have the same periodicity or pitch as the panel pixels but because the gate and data lines have narrower dimensions than the camera pixels, they provide sharper and more distinct signals. The intersections of the gate and data lines provide information about the position of the pixels. The pixel positions are subsequently used to generate a dynamic pixel map. Enhanced computational techniques use the pixel positions to determine the magnification of the imaging sensor head as well as the degree of rotation and offset of the panel pixel plane relative to the pixel plane of the imaging sensor head.
