Abstract

Moisture The embodiment of the present invention discloses an organic light emitting display panel and a manufacturing method thereof. Wherein, the organic light emitting display panel includes: an array of organic light emitting elements, a thin film encapsulation layer covering the array of organic light emitting elements, the thin film encapsulation layer includes at least two inorganic layers and at least two organic layers, the organic layer and the Inorganic layers are arranged alternately, at least one of the organic layers is provided with grooves, and transparent touch electrodes, at least part of the transparent touch electrodes are located in the grooves, the organic layer with the grooves and the At least one organic layer and at least two inorganic layers are included between the organic light-emitting element arrays. The technical solutions provided by the embodiments of the present invention can ensure the encapsulation reliability of the thin film encapsulation layer and improve the service life of the organic light-emitting element.

Description

technical field [0001] Embodiments of the present invention relate to the field of organic light emitting display technology, and in particular to an organic light emitting display panel and a manufacturing method thereof. Background technique [0002] Existing display panels generally have functions of touch and display, and in a display panel with a touch function, detection of a touch position is realized through touch electrodes. [0003] Generally, the touch electrodes are integrated and disposed on the protective film or the polarizer in the display panel, and this solution has higher requirements for making the protective film or the polarizer. Or integrate the touch electrode inside the thin film encapsulation layer of the display panel, for example, integrate the touch electrode between the organic layer and the inorganic layer of the thin film encapsulation layer. The lifetime of the light emitting element. Contents of the invention [0004] The present inventi...
