Problems solved by technology

Since the thickness of the thin-film packaging material is only a dozen microns, the distance between the touch sensor and the cathode is too close, and the electric field of the cathode affects the driving signal of the touch sensor, reducing the signal amount of the node, thereby causing the signal to change when the touch occurs. Smaller, making it difficult for the touch sensor to perceive the touch signal

Abstract

The invention provides a flexible touch panel, which is arranged on an OLED substrate. The flexible touch panel comprises a conductive layer, a first insulated layer, a first electrode layer, a secondinsulated layer, a second electrode layer and a protective layer arranged in sequence. The conductive layer is arranged on an encapsulation layer of the OLED substrate; the first insulated layer andthe first electrode layer are superposed on the conductive layer in sequence; a capacitive structure is formed among the first electrode layer, the second insulated layer and the second electrode layer; the capacitive structure is used for sensing a touch signal; the conductive layer is used for inputting a first voltage signal; and the first voltage signal enables the conductive layer to repel anelectric field line generated by the first electrode layer and shield signal interference between the first electrode layer and a negative electrode layer of the OLED substrate. The invention provides a fabrication method for the flexible touch panel and a touch apparatus. The signal interference of an electric field of the negative electrode layer to a touch sensor can be shielded, so that the touch sensitivity is improved.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a flexible touch panel, a preparation method thereof, and a touch device. Background technique [0002] With the development of display technology, organic light-emitting diode (Organic Light-Emitting Diode, OLED) touch panels are adopted by more and more electronic products. The flexible OLED touch panel has attracted much attention because of its flexibility. The touch sensor used in the flexible OLED touch panel is mainly of the plug-in type, that is, the touch sensor module is completed on the substrate and then bonded to the OLED substrate. However, the external touch sensor has a negative impact on the thinning and flexibility of the display module. [0003] In-cell touch technology integrates touch sensors on flexible OLED touch panels. At present, when the touch sensor is directly manufactured on the flexible OLED touch panel, a major problem is that the electron emissi...
