Abstract
The present invention is a touch panel with a heater for enhancing the bonding of optical adhesive, which comprises a cover lens and a sensing substrate mutually bonded by optical adhesive, wherein at least one heating electrode is configured on the other side of the sensing substrate. The heating electrode is formed by printing an opaque conductive material with a plurality of openings formed thereon and through which light is allowed to pass. When ultraviolet light is irradiating from one side of the heating electrode to the direction of the cover lens, the ultraviolet light can penetrate the optical adhesives through the openings on the heating electrode, so that the optical adhesives are effectively cured by the irradiation, and the bonding strength between the cover lens and the sensing substrate is improved.
