AI Technical Summary

Technical Problem

The design of the existing display substrate in the frame area is difficult to compatible with conventional integrated circuits, and the transmission trace of the data signal has a sudden resistance change, which affects the display effect.

Method used

By electrically connecting the first lead wire and the second lead wire in the first frame area of ​​the display substrate, the transmission order of the data signals is adjusted so that they are consistent with the data lines in the display area, and openings are provided on the power line to reduce the impact on the lead wire.

Benefits of technology

Compatibility with conventional integrated circuits is achieved, the resistance changes in data signal transmission traces are reduced, and the stability and compatibility of the display effect are improved.

Abstract

A display substrate includes: a display area and a frame area, wherein the frame area includes a first frame area located on one side of the display area. The display area includes: a plurality of sub-pixels, a plurality of first data lines, a plurality of second data lines, a plurality of first data connection lines, and a plurality of second data connection lines. The plurality of first data lines are electrically connected to the plurality of second data connection lines through the plurality of first data connection lines. The first frame area includes: a plurality of first data lead-out lines, a plurality of second data lead-out lines, a plurality of lead-out switching lines, and at least one first power line. The first data lead-out line includes: a first lead-out line and a second lead-out line. The first lead-out line is electrically connected to the second lead-out line through a lead-out switching line. The orthographic projection of at least one lead-out switching line on the substrate overlaps with the orthographic projection of the first power line on the substrate.
