In the quiet architecture of a single display pixel, an invisible accumulation has long undermined a promising technology. Researchers have now mapped the precise mechanics by which electrical charges become trapped at the boundary between oil and insulating material in electrowetting displays, causing colored oil to drift backward and images to destabilize. Their mathematical model reveals that this degradation follows a steady, linear progression — a finding that transforms an elusive failure mode into a quantifiable, and therefore manageable, phenomenon. In naming the mechanism clearly, the
