Abstract

The invention discloses a display panel and a display device. Multiple welding discs are included, the welding discs comprise first secondary parts and second secondary parts which are electrically connected, the first secondary parts have first length, the second secondary parts have second length, the second length is greater than the first length, the edges, close to a fastening area, of the display panel is first edges, the ends, close to the first edges, of the first secondary parts are first end parts, the distance from the first end parts to the first edges is first range, the ends, close to the first edges, of the second secondary parts are second end parts, the distance from the second end parts to the first edges is second range, and the second range is smaller than the first range. By lengthening the second secondary parts of the welding discs to increase the fastening area, the fastening effect is better, the signal transmission accuracy and stability of the fastening areaare improved, better compatibility is achieved when the electronic assembly is fastened, and the influence on the fastening of an electronic assembly caused by expansion caused by heat and contractioncaused by cold is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] In a display panel provided by the prior art, since the binding of electronic components such as flexible circuit boards usually needs to be carried out in a high-temperature environment, and the expansion coefficients of the display panel and the flexible circuit board are different in the high-temperature environment, resulting in flexible circuit boards, etc. The electronic components have poor contact when they are bound to the pads of the display panel, which affects the normal transmission of signals. Contents of the invention [0003] In view of this, the present invention provides a display panel, including: a base substrate; a binding area, the binding area includes a plurality of pads, the pads include a first sub-section and a second sub-section electrically connected, the first Th...
