Touch display apparatus, display panel, and all-in-one switch device

A display panel that comprises a data line and a gate line arranged therein and a pixel defined by the data line and the gate line, the display panel including a pixel electrode, a switching transistor, and a sensor pattern arranged therein,

• wherein the pixel electrode is disposed in each pixel;
• wherein the switching transistor is electrically connected between the pixel electrode and the data line;
• wherein the sensor pattern is electrically connected between a first electrode and a second electrode of the switching transistor;
• and
• wherein the switching transistor includes a semiconductor layer, both ends of which directly electrically contact the first electrode and the second electrode, respectively, and
• wherein the switching transistor completely overlaps the sensor pattern.

An all-in-one switch device, comprising:

• a first electrode electrically connected to a pixel electrode;
• a second electrode electrically connected to a data line;
• a third electrode electrically connected to a gate line;
• a semiconductor layer including a first end in contact with a first end of the first electrode and a second end in contact with a first end of the second electrode;
• and
• a sensor pattern including a first end in direct electrical contact with a second end of the first electrode and a second end in direct electrical contact with a second end of the second electrode,
• wherein the sensor pattern completely overlaps the semiconductor layer.
