Abstract
A process for integrating digitizer sensor array into flat panel displays. The sensor array is formed on the side of the display element (e.g., LC layer or OLED layer) where the pixel control switches (e.g., thin film transistors (TFTs)) of the display module are present, or on the other side of the display element where the pixel control switches are not present. In particular, the sensor array may be formed (a) before planarization layer of the pixel control switches, (b) after forming the planarization layer of the pixel control switches, (c) prior to forming the pixel control switches (e.g., formed on the substrate, before or after forming an electrode on the substrate), and/or (d) formed above or below a color filter layer, e.g., in the case of an LCD module, or above or below the encapsulating layer, e.g., in the case of an OLED display module.
