The present invention describes a planarization tape and a touch sensor assembly comprising a cover glass, a touch sensor film bonded to the cover glass by a layer of optically clear adhesive, and a planarization tape, the planarization A tape is releasably bonded to the touch sensor film. The planarizing tape includes a polymeric substrate and a peelable adhesive layer bonded to the substrate. The thickness of the substrate is between 250 microns and 5 millimeters, and the thickness of the adhesive layer is between 5 microns and 100 microns. The adhesive layer may be adapted to releasably bond to at least one of glass and cycloolefin polymer films. |
