1. A method for assembling a touch sensing apparatus, the touch sensing apparatus comprising a display panel, a plate comprising a top surface and a bottom surface opposite the top surface, and a frame assembly,
wherein the plate has a first curvature along at least a first edge of the top surface of the plate when uncoupled with the frame assembly, and
wherein the frame assembly comprises:
a first frame portion configured to extend over the first edge of the top surface of the plate;
a second frame portion configured to extend substantially parallel to a side surface of the plate adjacent the first edge; and
a support portion configured to provide support to the plate, and wherein the support portion is further configured to extend under at least an edge portion of the bottom surface of the plate adjacent the side surface;
the method comprising the steps of:
arranging a plurality of light emitters alongside a periphery of the plate, the plurality of light emitters configured to emit light propagating over the top surface;
arranging a plurality of detectors alongside the periphery of the plate, the plurality of detectors configured to receive light emitted from the plurality of light emitters; and
coupling the display panel, the plate, and the frame assembly,
wherein the step of coupling causes the first curvature of the plate to change to a second curvature.
