Abstract
A touchscreen display may include display chassis, a touchscreen sensor, and filters. The touchscreen sensor may include row conductors and column conductors spanning a display surface. Each of the filters may be coupled to one of the row conductors or the column conductors such that the row conductors and the column conductors are coupled to the filters. Each of the filters may be grounded to the display chassis. Each of the plurality of filters may be configured to allow a touchscreen sensor frequency band of interest to pass through said filter such that the touchscreen sensor is configured to detect touches. Each of the filters may be configured to filter out electromagnetic interference (EMI) on frequencies other than the touchscreen sensor frequency band of interest and to ground the EMI to the display chassis. The touchscreen sensor and the filters may form an EMI shield across the display surface.
