Narrow border touch display apparatus
A narrow border touch display apparatus is provided and includes a display layer and a self-capacitive touch-sensing layer. The self-capacitive touch-sensing layer is disposed on a surface of the display layer and includes a touch-sensing area and a wiring area adjacent to the touch-sensing area. The touch-sensing area is provided with a plurality of touch-sensing electrodes arranged in a matrix. Each of the touch-sensing electrodes is connected to a lead. The leads extend to the wiring area. A portion of the self-capacitive touch-sensing layer that is located within the wiring area extends over an edge of the display layer and is mounted on another surface of the display layer by bending.
