Flexible touch panel

Abstract

The invention relates to a flexible touch panel. The flexible touch panel comprises a substrate, an OLED packaging layer, a touch electrode metal layer and a touch packaging layer. According to the invention, self-capacitance touch electrodes are manufactured on the flexible touch panel. A high-speed switch controller is additionally arranged in the second area. Touch sensing signal leads are processed by the high-speed switch controller, and under the condition that the number of the touch units is not changed, the number of the touch sensing signal leads led out to touch bonding terminals isreduced, so that the position of a display bonding area is reserved, and the touch sensing signal leads can be conveniently realized on an oncell. Therefore, the display bonding area is separated from the touch bonding area, excessive concentration of the touch sensing signal leads and the display signal leads is avoided, and signal interference is avoided.

Problems solved by technology

Among them, the mutual capacitance type needs to use two layers of driving and sensing electrodes. For example, the mutual capacitance structure in an oncell needs to complete the bridging design where the driving electrode and the sensing electrode overlap. The process is difficult and the structure is complex.

Among them, the self-capacitance type only needs a single layer of electrodes, no bridging is required, the process is less, and the structure is simple. The touch display panel based on the self-capacitance type usually sets the electrodes for touch control inside the outer substrate of the display panel. Therefore, The overall thickness of the self-capacitive touch display panel is smaller and lighter, but compared with the mutual-capacitive structure, the number of touch sensing signal leads is too large, resulting in the inability to leave a display bonding position after the oncell design, which is difficult to realize in the oncell
