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.

Abstract: A serial communication method between a device and a host, in which the device reports touch data including a coordinate of a detected active stylus to a host. The host issues a write command that includes data indicating a request of a descriptor, to the device.
