AI Technical Summary

Technical Problem

The fingerprint recognition accuracy of the existing display panels is poor and misjudgment is prone to occur. This is mainly because the touch leads block the light-transmitting hole, resulting in a decrease in the amount of detected light injection.

Method used

Only one of the touch leads and the light-transmissive holes is provided in the sub-pixel interval area of ​​the display panel, so that the touch leads and the light-transmissive holes are located in different sub-pixel interval areas and are far apart, so as to avoid the touch leads from blocking the light-transmissive holes.

Benefits of technology

The amount of detected light that can be shot through the light-transmitting hole is effectively improved, the fingerprint recognition accuracy is enhanced, and the sufficient spacing between the touch lead and the sub-pixel and between the light-transmitting hole and the sub-pixel is ensured, thereby optimizing the touch performance.
