Claim:
1. An organic light-emitting diode (OLED) pixel driving circuit, comprising: a plurality of interlaced scanning and data lines; and a first defect detection unit electrically connected to a first endpoint of at least one of: a) the scanning lines, and b) the data lines, wherein the first endpoint is located at one end of the at least one scanning line or data line, the first defect detection unit comprises an organic light-emitting diode for detecting a defect in the at least one scanning line or data line, and the organic light-emitting diode comprises an anode disposed in the same layer as the data line or the scanning line and disposed on a substrate; an organic light-emitting layer covering the anode; and a cathode covering the organic light-emitting layer, wherein the cathode of the organic light-emitting diode is connected to a common ground terminal.
