Transparent display panel and manufacturing method thereof

Abstract

The invention discloses a transparent display panel and a manufacturing method thereof. The transparent display panel comprises a substrate, organic electroluminescent devices, pixel electrodes, light-emitting layers, opposite-direction electrodes and a conductive layer, wherein the substrate comprises a plurality of pixel areas and a light transmitting area surrounding the pixel area; the organic electroluminescent devices are arranged on the substrate, correspond to the pixel areas of the substrate and comprise thin film transistors which are arranged on the pixel areas of the substrate; the pixel electrodes are arranged on the thin film transistors and electrically connected with the thin film transistors; the light-emitting layers are arranged on the pixel electrodes; the opposite-direction electrodes are arranged in the pixel areas of the substrate and located above the light-emitting layers; the conductive layer is arranged above the light transmitting area, located between the two opposite-direction electrodes and used for connecting the two adjacent opposite-direction electrodes; the conductive layer is made from conductive materials with the evaporation temperature lower than 600 DEG C.

Description

technical field [0001] The invention relates to the field of designing semiconductor devices, in particular to a transparent display panel and a manufacturing method thereof. Background technique [0002] According to the market research firm IHS, the market value of transparent displays can reach US$100 million in 2015, and will jump to US$87 billion in ten years, with an annual growth rate of nearly twice. Its application fields include many aspects, such as: personal applications (watches, mobile phones, tablet computers, notebook computers, etc.); household appliance displays (refrigerators, microwave ovens, etc.), TV / large-screen displays; advertising displays, office displays, education, Architecture (windows); military use; head-up displays (cars, airplanes), etc. [0003] One of the main indicators of transparent display is its transparency (that is, light transmittance). Compared with many display panels, OLED panels have become the development of transparent displ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the defects in the prior art, the purpose of the present invention is to provide a transparent display panel and its manufacturing method, which can effectively solve the problems caused by the metal mask in the cathode manufacturing process of the existing transparent display panel. The deformation of the diaphragm and the blockage of the opening affect the alignment accuracy of the metal mask and the production of the transparent display panel.
