A high-accuracy OLED touch display panel structure of narrow border includes an upper substrate, a lower substrate, an OLED layer configured between the upper and lower substrates, a sensing electrode layer, a thin film transistor layer, a cathode layer, and an anode layer. The sensing electrode layer has a plurality of first conductor line units. The thin film transistor layer includes a plurality of gate lines, a plurality of source lines, and a plurality of second conductor line units. The plurality of first conductor line units and the plurality of second conductor line units form a sensing touch pattern structure for sensing an approaching external object. The plurality of first conductor line units and the plurality of second conductor line units are disposed corresponding to positions of the plurality of gate lines and the plurality of source lines.
