Abstract: Embodiments of the present application provide a demultiplexer circuit, a display panel and a driving method of a display panel. The display panel includes a first operating frequency and a second operating frequency. Responsive to the display panel being at the first operating frequency, the first switch unit is in a switched-on state and the second switch unit is in a switched-off state; responsive to the display panel being at the second operating frequency, both the first switch unit and the second switch unit are in the switched-on state.

Abstract: A touch control display substrate, a touch control display panel, and a touch control display device are provided. The touch control display substrate includes a substrate, a plurality of touch control electrode blocks, a plurality of first touch control switches, a plurality of compensation switches, a plurality of first signal lines, and a plurality of compensation signal lines. Each of the compensation signal lines is connected to one of the compensation switches and one of the touch control electrode blocks. Each of the touch control signal blocks is connected to the first touch control switches by the first signal lines, and is connected to the compensation switches by the compensation signal lines.

Abstract: An array substrate and a liquid crystal display panel are provided. By arranging scan lines on a second metal layer in the array substrate, a width of a channel of a thin-film transistor is not related to a width of a scan line, so that the width of the scan line can be increased to reduce resistance of the scan line. In addition, the impedance of the second metal layer is relatively small, so that the impedance of the scan line can be reduced. Furthermore, a channel width of the thin-film transistor is relatively small, which improves charging efficiency of the array substrate and reduces the distortion difference of scan signals.
