  • Patent number: 11826755
    Abstract: A panel includes a substrate, an array layer and an electrode array layer. The array layer is on a side of the substrate; the electrode array layer is on a side of the array layer away from the substrate; and the array layer includes an active layer, a gate metal layer and a source/drain metal layer. The substrate includes drive units arranged in an array, scan line groups, data lines extending in a second direction; and common signal lines extending in the second direction. The scan line group includes first scan lines and second scan lines, extending in a first direction. The first direction is perpendicular with the second direction. The electrode array layer includes drive electrodes arranged in an array; the drive electrodes correspond to the drive units; and the drive unit includes a first transistor, a second transistor, a third transistor, a first capacitor and a second capacitor.

  • Patent number: 11084033
    Abstract: A drive circuit and its drive method, and a panel and its drive method are provided. The drive circuit includes a step-up unit, a plurality of signal input terminals and a signal output terminal, which are electrically connected with each other. The step-up unit includes a first module, a second module, a third module and a first capacitor, which are electrically connected with each other. The first module is configured to transmit a signal of a third signal input terminal to a first electrode of the first capacitor. The second module is configured to transmit a signal of a fourth signal input terminal to a second electrode of the first capacitor. The third module is configured to transmit a signal of the third signal input terminal to the second electrode of the first capacitor, which further increases the signal of the first electrode of the first capacitor.
