Problems solved by technology

However, the metal traces currently used in OLEDs mainly include molybdenum (Mo), titanium (Ti), and aluminum (Al) with high elastic modulus. Although metals are more resistant to bending than inorganic films, but with With the continuous reduction of bending radius and the continuous increase of product bending times, it is difficult for the currently used metal materials to meet more and more stringent requirements. Under the current technical conditions, metal traces are prone to cracks after bending

Abstract

The present invention relates to a display panel and a manufacturing method thereof. The display panel utilizes the advantage that a conductive polymer can form a film over a large area, facilitates patterning, and has an electrical conductivity that is comparable to that of metal and not decreasing with an increase in temperature, excellent bending resistance, good conductance direction and the like. A conductive polymer material replaces the metal material of wires in the display panel to satisfiy the requirements for both conductivity and bending resistance.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a preparation method thereof. Background technique [0002] OLED (full name in English: Organic Light-Emitting Diode, referred to as OLED) devices are also called organic electro-laser display devices and organic light-emitting semiconductors. The basic structure of an OLED is a thin, transparent indium tin oxide (ITO) with semiconducting properties connected to the positive electrode of electricity, plus another metal surface cathode, wrapped into a sandwich structure. The whole structural layer includes: hole transport layer (HTL), light emitting layer (EL) and electron transport layer (ETL). When the power is supplied to an appropriate voltage, positive holes and surface cathode charges will combine in the light-emitting layer, and under the action of Coulomb force, they will recombine with a certain probability to form excitons (electron-hole pairs) in a...
