  • Publication number: 20210225884
    Abstract: An array substrate, a manufacturing method thereof, and a display panel are provided in the present application. A gate electrode and source and drain electrodes of different thickness are formed on an electroplated substrate by metal electroplating. By using a height difference between the gate electrode and the source and drain electrodes, a dielectric layer covering the gate electrode and exposing the source and drain electrodes is formed on a substrate, so that an active layer is electrically connected to the source and drain electrodes. Moreover, separation is realized by means of the dielectric layer and the gate electrode, so an etching stop layer is not needed, which simplifies an IGZO manufacturing process and reduces production costs.

  • Publication number: 20210104559
    Abstract: The present invention teaches a pixel unit including thin film transistors (TFTs) and pixel electrodes corresponding to the TFTs. The pixel electrodes are connected to the source electrodes of the TFTs. Each pixel electrode includes multiple arc-shaped electrode units arranged at intervals along an axial direction around a periphery of a corresponding TFT. The electrode units are electrically connected together. The present invention adopts arc-shaped pixels (similar to concentric circles) so that liquid crystal molecules are closer to being isotropic. Then, by having different vertical alignment (VA) TFT designs in the primary pixel region and secondary pixel region and utilizing the differences in W/L and capacitance, different voltage levels for primary pixel electrode and secondary pixel electrode are achieved. The color shift problem is improved and the viewing angle is enhanced.
