  • Patent number: 10515586
    Abstract: The present disclosure discloses a display panel and a display device. The display panel includes pixel circuits arranged in an array. Each pixel circuit includes a driving transistor, at least two switching transistors and at least two first auxiliary electrodes arranged in a one to one relationship to the switching transistors. By electrically connecting each of the first auxiliary electrodes with a gate of a related switching transistor, the first auxiliary electrode and the gate of the corresponding switching transistor have a same potential. A capacitor can be formed between the first auxiliary electrode and the active layer, and a capacitor is formed between the gate and the active layer.
    Type: Grant

  • Patent number: 10269829
    Abstract: An array substrate and a flexible display panel are provided. The array substrate includes a flexible substrate, a thin film transistor, a first metal layer, a second metal layer and a stacked structure including multiple inorganic layers. The thin film transistor includes a source, a drain, a channel and a gate. The gate of the thin film transistor is insulated from the source, the channel and the drain. The multiple inorganic layers include one or more buffer layers between the flexible substrate and the thin film transistor, one or more gate insulating layers between a channel area and the gate, and a first isolating layer between the thin film transistor and the second metal layer. At least one inorganic layer of the multiple inorganic layers has multiple openings at a position corresponding to a display area.
