Abstract

The invention provides an OLED touch control panel and OLED touch control device. The OLED touch control panel consists of: OLED display layer, the OLED display layer includes the cathode and the encapsulated layer set on one side of the said cathode. The touch layer is set on one side at the encapsulated layer far from the cathode, wherein the touch layer consists of: the first electrode chain set up in more than one interval, and the first electrode chain includes the first electrode of multiple electrical connections. The second electrode chain set in more than one interval, wherein the second electrode chain consists of the secondary electrode of multiple electrical connections, the second electrode chain and the first electrode chain are crossed with insulation; at least one first shield electrode, wherein the first shield electrode is set between the first electrode and the encapsulation layer, used to form the first electric field with the first cathode to improve the interaction capacitance between the first electrode and the secondary electrode. The OLED touch control panel of the invention has high detection accuracy.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to an OLED touch panel and an OLED touch device. Background technique [0002] With the development of display technology, OLED (Original Light Emitting Diode, OLED) display panel has the advantages of self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, uniform image quality, and fast response speed. to be used more and more. When the OLED display panel is applied in a touch device, usually after the OLED display panel is packaged, the touch module is attached to the packaging structure of the OLED display panel. However, in this structure, the touch module is closer to the OLED display panel, and the cathode of the OLED display panel affects the driving signal in the touch module, thereby reducing the interactive capacitance value in the touch module, making the touch The detection is not sensitive enough.
