Abstract
The present embodiments relate to an all-in-one switch device as well as a touch display apparatus and a display panel including such an all-in-one switch device. The all-in-one switch device includes a switching transistor electrically connected between a pixel electrode and a data line, and a sensor pattern connected between a first electrode and a second electrode of the switching transistor. One device is enough to provide both a switching function for display driving and a sensor function for sensing a touch position and/or a fingerprint, a separate touch sensor having a large size is unnecessary, and it is possible to precisely sense a touch position and/or a fingerprint without being affected by parasitic capacitance, even in a situation where a system has a structure or a circuit in which touch sensing based on capacitance is impossible.
