Abstract: The present disclosure provides an array substrate and a method for manufacturing the same, and a display apparatus. The array substrate comprises a shielding electrode driven independently, and the shielding electrode covers at least one gate line and/or at least one data line. The shielding electrode can isolate a signal of the at least one gate line and/or the at least one data line, so that the signal of the at least one gate line and/or the at least one data line is prevented from interfering with normal deflections of liquid crystal molecules of a liquid crystal display. Moreover, since the shielding electrode is driven independently, the shielding electrode will not affect a voltage of a common electrode of the liquid crystal display.

Abstract: A substrate and a photoelectric display device including the substrate are provided. The substrate includes a display region and seal material disposed in a periphery thereof. The substrate further includes a trapping buffer region which is disposed between the display region and the seal material and receives photoelectric display media. By providing the trapping buffer region, impact on the seal material by the excessive photoelectric display media can be mitigated or eliminated when the photoelectric display device is subjected to an external force or is flexed. The life time of the seal material is prolonged. A leakage of the photoelectric display media is avoided.
