Thus, a distance between electrodes (the detection electrode and a driving electrode) for detecting an input position can be set separately from a thickness of the display device, and therefore, reduction in detection sensitivity (detection reliability) for the input position due to increase in the electrostatic capacity can be suppressed.

  • Patent number: 10698516
    Abstract: A flexible touch-sensing component is formed on a release film by support provided from a first carrier substrate and a second carrier substrate. Then, the flexible touch-sensing component can be attached onto non-planar and curved cover plates through the reloading of a third carrier substrate, so that the touch panel can be lighter and thinner, and have a lower processing cost. In addition, the flexible touch-sensing component uses a film sensor that includes a metal nanowire conductive layer. Since the silver nanowire has flexibility, the touch sensor and the touch panel in the present disclosure can be used in flexible touch-sensing devices and curved-surface touch-sensing devices. Furthermore, based on application of an adhesive reactive ink, the released touch panel can be directly attached to target carrier substrate without adding an auxiliary layer of optical glue or hydrogel glue.
