AI Technical Summary

Technical Problem

Traditional embedded touchscreens suffer from poor visibility of touch electrodes and inconsistent display due to differences in the film structure between the touch area and the non-touch area.

Method used

Isolation pillars are set in both the touch area and the non-touch area to make the film structure of the two areas similar. The first sub-electrode on the isolation pillar is connected to the second sub-electrode in the area outside the isolation pillar in the non-touch area. The width of the second electrode for display is increased to reduce resistance and improve display uniformity.

Benefits of technology

By making the film structure of the touch area and non-touch area similar, the touch electrodes are prevented from becoming visible, thus improving the display uniformity and performance of the display panel.

Abstract

The application relates to a display panel and a display module. In the display panel, not only is a first sub-electrode on an isolation column reused as a touch electrode by arranging the isolation column in a touch area, but also the isolation column is arranged in a non-touch area, so that the film layer structures of the touch area and the non-touch area are similar, the display performance is improved, and the first sub-electrode on the isolation column in the touch area is prevented from being exposed due to a large difference between the film layer structures of the two areas. Furthermore, the first sub-electrode on the isolation column in the non-touch area is connected with a second sub-electrode in an area outside the isolation column, the width of the second electrode for display is increased, the resistance of the second electrode for display is reduced, the voltage drop of the second electrode for display is reduced, and the display uniformity of the display panel is improved.
