Abstract
A personal electronic device includes a programmable display and a programmable keypad, wherein at least one of the programmable display and the programmable keypad includes a capacitive touch sensor and an EL panel in a unitary structure. A conductive layer shields the capacitive touch sensor from the EL panel and can be a separate layer or be incorporated into either the capacitive sensor or the EL panel. The conductive layer includes antimony tin oxide (ATO), other conductive oxide, or a conductive polymer, such as Orgacon™ 3010.
