[0003] However, in the structure of the existing display panel, in order to reduce the area of the non-display area occupied by the integrated circuit and realize the design of the narrow frame, usually the distance between the two signal output terminals of the integrated circuit is smaller than that between the signal lines. At the same time, the output terminals of the integrated circuit are distributed on both sides of the integrated circuit, which makes the length of the signal transmission line connecting the integrated circuit and the signal line different, resulting in a difference in the impedance between the signal transmission lines, thus making the transmission There is a difference between the signals to the signal line, which affects the display effect or touch effect of the display panel

The invention discloses an array substrate, a display panel and a display device. The array substrate comprises an integrated circuit. The integrated circuit comprises multiple signal output ends and a first symmetry axis stretching in the first direction. The signal output ends of the integrated circuit are symmetrically distributed on the two sides of the first symmetry axis. A region covered with signal transmission lines is an axial symmetry figure symmetric about the first symmetry axis, and on one side of the first symmetry axis, the region covered with the signal transmission lines sequentially comprises a first region, a second region and a third region in the second direction, and the second direction is orthogonal with the first direction; the line width of the first signal transmission lines in the first region and the third region is W1, the line width of the second signal transmission lines in the second region is W2, and W2 is smaller than W1. According to the embodiment, the impedance differences between the signal transmission lines can be reduced, and the display effect of the display panel can be improved.
Description
technical field [0001] The present application relates to the field of display technology, and in particular to an array substrate, a display panel including the above-mentioned array substrate, and a display device including the above-mentioned display panel. Background technique [0002] In the existing display technology, an integrated circuit is usually provided on the display panel, and the integrated circuit is used to provide various signals to the display area of the display panel, for example, to provide data signals to the display area during the display period, while the integrated touch display In the technology, it is also necessary to provide touch driving signals to the display area during the touch period, so signal transmission lines need to be arranged on the array substrate to transmit the signals output by the integrated circuit to the signal lines. [0003] However, in the structure of the existing display panel, in order to reduce the area of the no...
