    Abstract: A display component and a display device are provided. The display component includes a display panel including a first substrate, a thin-film transistor array layer, a second substrate and a coil-containing film layer. The coil-containing film layer at least includes a first metal layer, a first insulation layer, a second metal layer, and a second insulation layer. The first metal layer includes at least one first coil and the second metal layer includes at least one signal line, where the one first coil of the first metal layer is electrically connected to one or two signal lines of the second metal layer. An orthographic projection of the first coil on the first substrate is at least partially in the display region. The display component further includes a coil drive circuit, where the coil drive circuit is electrically connected to each of the first coil and the signal line, respectively.

    Abstract: A liquid display panel, and a display device are provided. The liquid display panel includes an array substrate. The array substrate includes a base substrate, a plurality of data lines, a plurality of scanning lines, and an auxiliary electrode. The data lines and the scanning lines intersect to form a plurality of pixels arranged in an array. Each pixel includes a first sub-pixel and a second sub-pixel adjacent to each other. Each first sub-pixel includes a first pixel electrode and a first electrode, while each second sub-pixel includes a second pixel electrode. The second sub-pixel has an area larger than the first pixel; and the second pixel electrode has an area larger than the first pixel electrode. At least a portion of the auxiliary electrode and the first electrode overlap with each other to form a first auxiliary capacitance for the first sub-pixel, and an overlap region between the auxiliary electrode and the first electrode extends into the second sub-pixel of a same pixel.

    Abstract: A driving circuit includes a first signal-input terminal, a second signal-input terminal, a third signal-input terminal, a fourth signal-input terminal, a signal-output terminal, and a voltage-boosting unit including a first module, a second module, a third module, and a first capacitor. The first module transmits the signal at the third signal-input terminal to a first terminal of the first capacitor during a first time period, and blocks signal transmission during a second time period. During the first time period and the second time period, the second module transmits the signal at the third signal-input terminal to the third module to allow the signal at the fourth signal-input terminal to be transmitted to a second terminal of the first capacitor. During a third time period, the second module and the third module both block signal transmission. The first terminal of the first capacitor is connected to the signal-output terminal for output.

    Abstract: A touch-control display panel, driving method, and a touch-control display device are provided. The touch-control display panel includes: a display area including a plurality of pixels; a non-display area; a first substrate; and a second substrate opposing the first substrate. A portion of the first substrate in the first region includes a pixel electrode layer and a first electrode layer. The first electrode layer is located on a side of the pixel electrode layer away from the second substrate and includes a plurality of first electrodes. The pixel electrode layer includes a plurality of pixel electrodes. A touch-control electrode layer is located on a side of the second substrate toward the first substrate and includes a plurality of touch-control electrodes. Along a direction perpendicular to the touch-control display panel, each touch-control electrode of the plurality of the touch-control electrode overlaps with and connects with one or more first electrode of the plurality of the first electrodes.
