AI Technical Summary
Technical Problem
Current OLED display panels suffer from significant color deviation issues due to the presence of via holes in the conductive layers, which affect the flatness of the electrodes and lead to display defects.
Method used
The display panel design positions the orthographic projections of via holes outside the pixel openings, ensuring that signal lines intersect and connect outside the pixel opening area, forming a mesh structure to avoid display defects and improve color uniformity.
Benefits of technology
This design enhances display quality by reducing the impact of via holes on electrode flatness, thereby improving color accuracy and yield, particularly for blue light-emitting units, and simplifies wiring complexity.

Abstract
The present application discloses a display panel and a display device, wherein the display panel comprises an array substrate, the array substrate comprises a substrate, a first conductive layer, an insulating layer, and a second conductive layer, the first conductive layer comprises a first signal line and a second signal line extending in a first direction, and the second conductive layer comprises a third signal line and a fourth signal line extending in a second direction, and the third signal line and the fourth signal line transmit the same signal; along a direction perpendicular to the substrate, the first signal line and the third signal line have a first overlapping region and are electrically connected in the first overlapping region, the second signal line and the fourth signal line have a fourth overlapping region and are electrically connected in the fourth overlapping region, the first signal line and the fourth signal line have a second overlapping region and are insulated, and / or, the second signal line and the third signal line have a third overlapping region and are insulated, and the orthographic projections of the second overlapping region and the third overlapping region in the substrate are both located outside the orthographic projection of a type of pixel aperture in the substrate. The display panel according to the present application can improve the color deviation of the display panel.
