AI Technical Summary

Technical Problem

Existing display devices that integrate fingerprint recognition and touch functions are relatively thick and prone to moiré patterns, affecting the display effect.

Method used

The fingerprint sensing layer and touch layer are set on the same layer, and the fingerprint recognition area and touch area are designed as patterned areas. The fingerprint recognition and touch functions are integrated without increasing the cost. By optimizing the layout of the metal layer and the connection of the signal transmission line, the compatibility of on-screen touch function and fingerprint recognition function is achieved.

Benefits of technology

It achieves compatibility between fingerprint recognition and touch functions, maintains good display performance, does not increase costs and avoids moiré patterns, and improves space utilization and manufacturing precision.

Abstract

Embodiments of the present application disclose a display panel, a display device and a control method. The display panel of one embodiment comprises: a substrate, an array substrate arranged on the substrate, a touch layer arranged on the array substrate, and a fingerprint sensing layer arranged in the same layer as the touch layer, wherein the touch layer comprises: a first metal layer arranged on a side of the array substrate away from the substrate, and a second metal layer arranged on a side of the first metal layer away from the substrate, and the orthographic projections of the first metal layer and the second metal layer on the substrate overlap to form a plurality of patterned touch areas; the fingerprint sensing layer comprises: a third metal layer arranged in the same layer as the first metal layer, and a fourth metal layer arranged in the same layer as the second metal layer, and the orthographic projections of the third metal layer and the fourth metal layer on the substrate jointly form a patterned fingerprint identification area, wherein the number of the touch areas is greater than the number of the fingerprint identification area.
