  • Patent number: 11086172
    Abstract: A pixel unit, a display panel and a display device are provided. The pixel unit includes: a first sub-pixel, comprising a first sub-region and a second sub-region; and a second sub-pixel, disposed adjacent to the first sub-pixel and comprising a third sub-region and a fourth sub-region; wherein the first sub-region is disposed adjacent to the third sub-region, and the second sub-region is disposed adjacent to the fourth sub-region; wherein a divided voltage of the first sub-region is same as a divided voltage of the third sub-region; the divided voltage of the first sub-region, a divided voltage of the second sub-region and a divided voltage of the fourth sub-region are different from one another. The pixel unit of the embodiment is advantageous for improving the washout and color shift problem of a larger side view angle and improving the optical characteristics of the viewing angle.

  • Patent number: 10928686
    Abstract: An array substrate, a liquid crystal display panel and a display device are provided. The array substrate includes: a substrate; a common electrode and a gate electrode, both disposed on the substrate; and a shielding electrode, disposed on the common electrode and the gate electrode, wherein an orthographic projection of the shielding electrode on the substrate is overlapped with an orthographic projection of the gate electrode on the substrate as well as an orthographic projection of the common electrode on the substrate, and the shielding electrode is electrically connected to the common electrode. In the embodiment of the disclosure, the shielding electrode is disposed on the common electrode and the gate electrode, so that the influence of the voltage difference formed by the gate electrode and the common electrode can be effectively shielded, thereby eliminating the phenomenon of push mura.
