Abstract
An information handling system presents visual images at a display that includes a display panel having a capacitive touch detection surface supported by an indium tin oxide layer disposed between a front layer, such as polarizer, and a display cell. To prevent excessive charge build up associated with the capacitive touch detection surface, a conductive ink is applied at the display panel perimeter and interfaced with a ground at the rear side of the display panel. In one example embodiment, a non-conductive ink insulates the conductive ink from the display panel except as desired to transfer excess charge from the indium tin oxide layer. The conductive ink may interface directly with the indium tin oxide layer or indirectly through a second non-conductive ink having greater conductivity than the insulative non-conductive ink.
