Optical-touch calibration method and optical-touch panel for calibrating the deformation bias on the optical-touch panel
An optical-touch calibration method and an optical-touch panel are disclosed herein. The optical-touch calibration method is suitable for the optical-touch panel including a projective light source and a line optical sensor. The optical-touch calibration method includes steps of: generating a projective beam by the projective light source, and the projective beam being reflected to the line optical sensor; utilizing the line optical sensor to measure the reflected projective beam for obtaining a reflected intensity curve relative to a linear coordinate axis; calculating an intensity difference between the reflected intensity curve and a reference intensity curve; and, adjusting an emitting power of the projective light source if the intensity difference exceeds a threshold value.
