A pixel matrix is determined for a capacitive touch panel. The pixel matrix comprises pixel values representative of mutual capacitance of respective pixels of the capacitive touch panel. A difference matrix is generated from the pixel matrix. The difference matrix contains differences in pixel values for respective pixels of the capacitive touch panel with respect to pixel values of adjacent pixels. A determination may then be made from the difference matrix whether respective ones of the pixels of the capacitive touch panel contain a discontinuity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Differential pixel test for capacitive touch screens","description":"Techniques are described for testing a capacitive touch panel for the presence or absence of discontinuities.
