  • ORGANIC LIGHT EMITTING DIODE PIXEL DRIVING CIRCUIT AND DISPLAY APPARATUS OF SAME
    Publication number: 20200135094
    Abstract: The present disclosure provides an OLED pixel driving circuit and an OLED display apparatus utilizing the circuit scheme of 3T1C. The normal displaying mode and detecting mode of the pixel driving circuit both include two phases by controlling the conductions of different transistors. And, the pixel driving circuit is capable of implementing corresponding data compensation under the displaying mode according to the detected voltage threshold Vth of the driving TFT and the intrinsic conductivity factor value k of the aged OLED. This is capable of improving the uniformity of display and the illuminating efficiency.
