Abstract
A touch-sensing display apparatus includes a first substrate, a second substrate, a plurality of touch sensing structures, and a display medium. The first substrate has a plurality of pixels and scan lines, and a read-out line. Each touch sensing structure includes a sensing active device, a sensing space, and a bridge electrode. Each sensing active device is disposed on the first substrate and includes a bottom gate, a channel, a source, a sensing electrode, and a top gate. The top gate has an opening to form a first electrode and a second electrode that are electrically isolated. When pressed, the bridge electrode contacts the top gate to electrically connect to the first and second electrodes, so that control of the channel is transformed from one of the top gate and the bottom gate to both the top and the bottom gates, thereby forming a sensing current in the sensing electrode.
