Abstract

The invention discloses a display panel and a display device. The display panel comprises a high-transmittance area, a wiring area and a display area, the display panel comprises data lines and scanning lines, wherein the data lines extend in the first direction, and the scanning lines extend in the second direction; the data line comprises at least one first type of data line, and the first type of data line comprises a first sub-data line located in the display area and a second sub-data line located in the wiring area; in the first direction, the maximum length value of the high-light-transmittance area is a first length L1, in the second direction, the maximum length value of the high-light-transmittance area is a second length L2, and L1 is smaller than L2; in the second direction, the wiring area comprises a center wiring area and an edge wiring area, the resistance value of the unit length of the second sub-data line of the center wiring area is r1, the resistance value of the unit length of the second sub-data line of the edge wiring area is r2, and r1 is smaller than r2. The unit length resistance values of the second sub-data lines with different lengths in the wiring area are adjusted, so that the load difference is improved, and the display uniformity is improved.

Description

technical field [0001] The present invention relates to the field of display, in particular to a display panel and a display device. Background technique [0002] With the innovation and development of display technology, it has gradually become closely related to our lives, such as traditional mobile phones, tablets, TVs and PCs, and now smart homes, smart wearable devices, VR, car displays, etc. In addition to the role of display, in order to enrich the user experience, multiple functions such as face recognition, intelligent monitoring, and human-computer interaction are often integrated on the panel, that is, more hole areas need to be integrated on the panel. With the introduction of holes, the originally regularly arranged wirings on the display panel need to be arranged around the holes, which greatly increases the non-display frame around the holes; and due to the load difference, it is easy to cause uneven display. Therefore, how to optimize the wiring distribution...
