    Abstract: A pixel driving circuit includes a data writing sub-circuit, a driving sub-circuit, and a control sub-circuit. The data writing sub-circuit is configured to: in response to a first scanning signal and a third scanning signal, write a first data signal into the driving sub-circuit; and in response to a second scanning signal and the third scanning signal, write a second data signal into the driving sub-circuit. The control sub-circuit is configured to, in response to an enable signal, connect a driving transistor to a first power supply voltage signal terminal and an element to be driven. The driving sub-circuit is configured to: according to the first data signal and a first power supply voltage signal, output a driving to signal; and according to the second data signal and the first power supply voltage signal, control an operating state of the element to be driven.

  • Patent number: 10332917
    Abstract: The present disclosure provides a pixel unit and a method for producing the same, an array substrate and a display apparatus. The pixel unit includes: a thin film transistor; an insulation layer formed at least on a drain electrode of the thin film transistor and formed therein with a via hole which extends through the insulation layer to expose the drain electrode of the thin film transistor below the insulation layer; a pixel electrode formed on the insulation layer and electrically connected to the drain electrode of the thin film transistor at the via hole; and at least one elevating layer formed below the via hole and located below a part of the drain electrode exposed from the via hole such that the exposed part has a height greater than the height of the parts of the drain electrode adjacent to the exposed part. The depth and slope of the via hole is reduced by adding the elevating layer below the via hole.
