AI Technical Summary

Technical Problem

The existing flexible touch display panel has a large line width or is wound around the border, resulting in a high risk of accidentally touching the active brushstroke.

Method used

A flexible touch display panel is designed, including a display area, a binding area and a bending area. By setting a winding design of snake-shaped traces in the binding area, the trace width and number of windings at the border are reduced, thereby reducing the risk of accidentally touching.

Benefits of technology

By reducing the trace width and number of windings at the border, the risk of accidentally touching by active brushstrokes is reduced, and the impedance between touchstrokes tends to be consistent, improving the transmission quality of touch signals.

Abstract

A flexible touch-control display panel, comprising a display area, a binding area and a bending area. The flexible touch-control display panel comprises binding terminals located in the binding area, touch control electrodes located in the display area, and touch control traces. Each touch control trace comprises a first trace portion and a second trace portion, which are connected to each other, wherein the first trace portion is connected to the corresponding touch control electrode; the second trace portion is connected to the corresponding binding terminal; the first trace portion extends from the display area, via the bending area and to the binding area; and the second trace portion is located in the binding area.
