Abstract: A touch display apparatus includes a display panel, first light-emitting elements and a first conductive layer. The first light-emitting elements are disposed on a first auxiliary display area of the display panel. The first conductive layer is disposed on the display panel and includes first mesh-shaped touch electrodes and first dummy electrodes. Each of the first dummy electrodes is disposed between two adjacent first mesh-shaped touch electrodes and is structurally separated from the two adjacent first mesh-shaped touch control electrodes. At least one portion of the first dummy electrode is electrically connected to at least one of the first light-emitting elements disposed in the first auxiliary display area.

Abstract: Disclosed are a touch display circuit and a touch display device. The touch display circuit includes a touch circuit and a light-emitting element set. The touch circuit includes a first touch electrode and corresponding plurality of second touch electrodes. The first touch electrode receives an emitting signal. The plurality of second touch electrodes respectively generate a plurality of sensing signals. A first end of the light-emitting element set is directly coupled to the first touch electrode and receives the emitting signal as a first driving signal. A second end of the light-emitting element set receives a second driving signal. As such, the touch display circuit is able to drive the touch circuit and the light-emitting element set simultaneously to simplify the circuit design.
