Huanda WU has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11605651
    Abstract: A display panel and a display device are provided. A pixel electrode of the display panel includes a pixel electrode body and a pixel electrode extension. The pixel electrode body is positioned within the light-emitting section and the pixel electrode extension is positioned within the light-shielding section. When an insulating layer positioned on an overlapping section is perforated, the pixel electrode extension is electrically connected to the signal electrode of other sub-pixel units via a repair line, thereby solving a technical problem that existing display panels possess a limited effect on repairing bright spots.

  • Patent number: 11164894
    Abstract: The present invention provides a display panel and a manufacturing method thereof. The display panel includes a common electrode layer, a pixel definition layer, a light emitting layer, a transparent pixel electrode layer, and an electrode connecting layer which are sequentially stacked. An electrode connecting portion is formed on the electrode connecting layer and electrically connected with the transparent pixel electrode layer and a signal electrode. Because a common electrode is disposed in a light emitting direction away from the light emitting layer, a light transmittance is not required.

  • Patent number: 10802348
    Abstract: An array substrate, display panel and display device. The array substrate includes: a source-drain metal layer, a pixel electrode layer, an insulation layer located between the source-drain metal layer and the pixel electrode layer, and a plurality of sub-pixels distributed in an array. Each sub-pixel corresponds to a drain electrode contained in source-drain metal layer, a pixel electrode contained in pixel electrode layer, and a drain through-hole defined in insulation layer. The pixel electrode is connected to the drain electrode via the drain through-hole. For any one row of the array, in a column direction, each drain electrode through hole is located at the same side of the sub-pixel 10 corresponding to the drain electrode through hole. The sub-pixels includes two adjacent support sub-pixels in a row direction, and the two drain through-holes respectively corresponding to the two adjacent support sub-pixels are unaligned in the column direction.
