A flexible substrate is formed on the patterned release layer, wherein the flexible substrate covers the patterned release layer and a portion of the flexible substrate contacts the carrier substrate. An adhesive force between the patterned release layer and the flexible substrate is larger than an adhesive force between the patterned release layer and the carrier substrate. A device layer is formed on the flexible substrate. A display layer is formed on the device layer. The flexible substrate and patterned release layer are cut simultaneously. The patterned release layer being cut is separated from the carrier substrate, wherein the flexible substrate, the device layer and the display layer which have been cut are sequentially disposed on the separated patterned release layer.

  • Publication number: 20130059128
    Abstract: The present disclosure relates to a touch-on-lens (TOL) device and a method for manufacturing the same. The method includes forming a plastic layer and a touch layer; cutting the plastic layer and the touch layer; and filially laminating the plastic layer and the touch layer after cutting to a strengthened lens. The method can not only help keep good mechanical property but can also help improve the efficiency of mass production. Moreover, the present disclosure adopts a photoetching process to form a sensing pattern, thereby making the circuit thinner and beautifying the appearance.
