A pixel driving circuit and method, an array substrate, and a display apparatus, wherein the pixel driving circuit comprises a data line, a first scan line, a signal control line, a light emitting device, a storage capacitor, a driving transistor and four switching transistors. The conductor assembly includes a plurality of the first electrical conductors each covered with an insulator and helically wound in a first direction to form an inner coil with a lumen. Once these acceleration levels are achieved, the slider is moved by a V-beam shaped actuator arrangement to position the microdetonator relative to a secondary lead to start an explosive train in a munitions round.
