Abstract
A touch-screen display apparatus, the apparatus may include first and second sheets having opposed major surfaces and a size and shape defined by a periphery. The periphery may be defined by opposed ends and opposed edges. The first and second sheets may each have a conductive pattern including a pair of opposed busbars and a plurality of traces electrically coupled to, and extending between, corresponding pairs of opposed busbars. The transparent force sensing (TFS) sheet may have opposed major surfaces and a variable resistance which is related to a force exerted upon one or more of its major surfaces. The TFS sheet may be situated between the first and second sheets. The apparatus may also include one or more separation portions situated between the TFS sheet and the first or second sheet to bias the TFS sheet apart from the first or second sheet.
