Display panel and display device

Abstract

The invention discloses a display panel and a display device. The adjacent sub-binding areas of the display panel are respectively a first sub-binding area and a second sub-binding area; the fan-out line correspondingly and electrically connected with the binding bonding pad nearest to the second sub-binding area in the first sub-binding area is the ith fan-out line; the fan-out line correspondingly and electrically connected with the binding bonding pad nearest to the first sub-binding area in the second sub-binding area is the jth fan-out line; the jth fan-out line comprises a jth straight line section; the ith fan-out line comprises an ith broken line section; the included angle between the first part of the ith broken line section and the jth straight line section is smaller than a first included angle threshold value, and the difference between the included angle between the second part of the ith broken line section and the second direction and the included angle between the jthstraight line section and the second direction is smaller than a second included angle threshold value; the length difference value of the jth straight line section and the ith broken line section issmaller than a preset length value; and the included angle between the first part and the second part of each fan-out line comprising the first part and the second part is gradually increased along the direction deviating from the second sub-binding area.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] In a conventional display device, the driver chip needs to provide signals to the display area of ​​the display panel through fan-out lines, so as to drive the display panel for display. [0003] Due to the location of the driver chip and the signal lines in the display area, the lengths of the fan-out lines from the output pins of the driver chip to the signal lines in the display area are different. Especially when multiple driver chips are installed, the impedance of each fan-out line corresponding to the same driver chip is slightly different, but the impedance of two adjacent fan-out lines of adjacent driver chips is very different, and there is a sudden change in impedance, which makes the transmitted signal waveform serious. Distortion, resulting in problems such as split scree...
