摘要： The present disclosure provides a transistor acoustic sensor element and a method for manufacturing the same, an acoustic sensor and a portable device. The transistor acoustic sensor element comprises a gate, a gate insulating layer, a first electrode, an active layer and a second electrode arranged on a base substrate, wherein the active layer has a nanowire three-dimensional mesh structure and thus can vibrate under the action of sound signals, so that the output current of the transistor acoustic sensor element changes correspondingly. Since the active layer having the nanowire three-dimensional mesh structure can sensitively sense weak vibration of acoustic waves, the sensitivity to sound signals of the transistor acoustic sensor element is improved.

摘要： Provided are a display substrate and a detection method therefor, and a display apparatus. Compensation sub-circuits that are in one-to-one correspondence with each stage of a shift register are arranged in a gate driving circuit, and a first capacitor in each compensation sub-circuit is thus charged under the control of a detection input circuit when each stage of the shift register outputs a signal stage by stage; and an output control circuit is used to disconnect the compensation sub-circuit from a pull-up node of the corresponding stage of the shift register. The triggering of each stage of the shift register is stopped after each stage of the shift register (CR(n)) completes outputting, and the output control circuit provides a signal of a first power voltage end to the pull-up node of the corresponding stage of the shift register under the control of a second control end and the first capacitor.
