Abstract
A micro LED touch display pane of reduced thickness includes a substrate, a display driving layer, micro LEDs on the display driving layer, and common electrodes connecting to the micro LEDs. The micro LEDs are spaced apart from each other and coupled to the display driving layer. The common electrodes cover the micro LEDs. The touch display panel further includes first and second electrodes. The common electrodes and the first electrodes are defined in one layer, insulated from the second electrodes. The first electrodes and the second electrodes cooperatively form mutual-capacitance touch sensing structures.
