An in-cell OLED touch panel structure of narrow border includes an upper substrate, a lower substrate, an OLED layer configured between the upper and lower substrates, a black matrix layer, a first sensing electrode layer, a second sensing electrode layer, and a thin film transistor layer. The molecular wire transistor comprises a pair of crossed wires, with at least one of the wires comprising a doped semiconductor material. A sliding member is slidably coupled to the conductor and moves with the piston or cylinder.
