Abstract

The invention discloses a touch panel and manufacturing method thereof and a display device, wherein the touch panel comprises: a first substrate and a second substrate oppositely disposed; an organic light emitting layer located between the first substrate and the second substrate, wherein the organic light emitting layer includes at least a cathode layer formed by a plurality of strip-like cathode electrodes; and a first touch layer located between the first substrate and the second substrate, wherein the first touch layer comprises a plurality of first touch electrodes, the first touch electrode comprises at least one first touch sub electrode the projection on the organic light emitting layer of which is located between two adjacent cathode electrodes. The technical solution of the invention can reduce at least electromagnetic interference between the first touch layer and the cathode electrode, and thus can improve the touch effect and the display effect. In addition, the invention can further reduce manufacture procedure of the process and reduce product costs.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a touch panel, a manufacturing method thereof, and a display device. Background technique [0002] AMOLED (Active Matrix Organic Light Emitting Diode, active matrix organic light-emitting diode) has the characteristics of self-illumination, low power consumption, fast response speed, high contrast and wide viewing angle. Therefore, AMOLED has a wide range of applications in the field of display technology. Application prospects. [0003] With the development of display technology, a touch structure will be integrated in the AMOLED display panel to realize the touch function. In the prior art, in order to realize the touch function of the AMOLED display panel, the touch control structure is integrated with the AMOLED display structure in the form of On-Cell. However, for the AMOLED display panel produced in this integrated form, when the display panel is working, electromagneti...
