AI Technical Summary

Technical Problem

In the existing technology, the monitoring electrodes of foldable display panels are easily affected by temperature drift and environmental factors, which leads to errors in the monitoring results and makes it impossible to accurately detect the bending angle and the degree of material deformation fatigue.

Method used

A first monitoring electrode and a second monitoring electrode are set in the bent display area of ​​the folding display panel. The first monitoring electrode serves as a control group for the second monitoring electrode. By calculating the resistance change values ​​of the two electrodes, the effects of temperature drift and environmental factors are offset, thereby improving the monitoring accuracy.

Benefits of technology

It effectively reduces the impact of temperature drift and environmental factors on monitoring results, improves the detection accuracy of bending angle and material deformation fatigue of foldable display panels, and protects the screen from damage.

Abstract

The application discloses a folding display panel and a display device. The display device comprises the folding display panel, and the folding display panel comprises a bending display area, and the bending display area comprises a first monitoring electrode and a second monitoring electrode. The first monitoring electrode is located in the bending display area and is arranged along a first direction. The second monitoring electrode is also located in the bending display area and has a detection part. The detection part is located in the bending display area and forms a preset included angle with the first direction. The detection part is used for detecting a bending angle of the folding display panel. The folding display panel provided by the application can offset the resistance change value of the second monitoring electrode caused by temperature drift or other environmental factors by calculating the resistance change value of the first monitoring electrode, so that errors of the detection part in monitoring the bending angle and material deformation fatigue degree of the folding display panel are avoided, the monitoring precision of the detection part is improved, and the screen is protected from being damaged.
