Touch sensitive displays with layers of sensor plates providing capacitance based proximity sensing and related touch panels

A touch sensitive display comprising:

• an image rendering layer that is configured to control light transmissivity through pixel locations therein responsive to a display control signal;
• a metallic reflector layer that is configured to direct light through the image rendering layer;
• a plurality of first sensor plates that are arranged in a plurality of spaced apart columns on a first layer between the image rendering layer and the metallic reflector layer, wherein each of the first sensor plates are spaced apart and serially connected in each column and are electrically isolated from first sensor plates in other columns;
• a plurality of second sensor plates that are arranged in a plurality of spaced apart rows on a second layer between the first layer and the metallic reflector layer, wherein each of the second sensor plates are spaced apart and serially connected in each row and are electrically isolated from the second sensor plates in other rows,
• wherein the metallic reflector layer extends beneath at least a majority of the first and second sensor plates;
• and
• a position detection circuit that is configured to electrically charge the first sensor plates, the second sensor plates, and the metallic reflector layer to generate capacitive coupling to an adjacent user object and detect therefrom a location of the user object relative to the columns of first sensor plates, relative to the rows of second sensor plates, and relative to the metallic reflector layer in a direction away from the columns and rows of the first and second sensor plates.
