The invention discloses a display panel assembly and an adjusting method thereof, and a display device. The display panel assembly comprises a display panel, a drive circuit and a control circuit. Display panel is provided with a display area and a fan-out area. The display area is provided with multiple first data lines. The fan-out area is provided with multiple second data lines with various lengths, and the multiple second data lines are connected with the first data lines. The drive circuit comprises a functional circuit and an adjustable resistor set which is connected with the output end of the functional circuit. The second data lines are coupled with the output end of the functional circuit via the adjustable resistor set which is used for reducing impedance difference of connection lines from the output end of the functional circuit to the first data lines. The control circuit is used for controlling resistance of the adjustable resistor set. Therefore, a situation of oversized signal delay difference among all the connection lines can be avoided, and thus excellent display of the display panel with uniform color and brightness can be realized.

A liquid crystal display (LCD) has a pixel matrix, a plurality of shift registers, a plurality of common voltage generators, a plurality of common voltage buffers, and a plurality of primary bidirectional switch circuits. The shift registers sequentially output gate signals to scan lines of the pixel matrix. The common voltage generators output initial common voltages according to the gate signals. The common voltage buffers are configured to buffer the initial common voltages to output a plurality of common voltages to a plurality of common voltage lines of the pixel matrix. Each of the primary bidirectional switch circuits is configured to control electrical connection between two of the common voltage lines according to one or more gate signals outputted from at least one of the shift registers.

The disclosure provides a touch display panel. A scan line enters a display mode and a touch mode in a scan period. In the display mode, the scan line receives a first voltage to turn off a switch unit and enable a pixel unit to receive a pixel voltage signal from a first signal transmission line; and in the touch mode, the scan line receives a second voltage to turn on the switch unit and disable the corresponding pixel unit to stop receiving the pixel voltage signal, such that a sensing pixel unit outputs a touch sensing signal to the first signal transmission line through the switch unit, wherein the first voltage is greater than the second voltage. In the disclosure, an aperture ratio of the touch display panel is improved efficiently to meet the requirement of narrow border design of the touch display panel.

A liquid crystal display panel and a fan-out area thereof are provided. The fan-out area is arranged in a peripheral circuit area of the liquid crystal display panel and includes a middle wire and multiple fan-out wires arranged at two sides thereof. The middle wire and the fan-out wires each are disposed with at least one first wire pattern. Along each of directions toward the middle wire, widths of the first wire patterns of different wires are successively increased and / or lengths of the first wire patterns are successively decreased. The first wire patterns of a same wire have same width and length. Accordingly, the present invention can reduce the resistance differences among the wires in the fan-out area, color washout and non-uniform brightness caused by the resistance differences can be relieved or avoided, and is beneficial to the narrow border design of the liquid crystal display panel.
