Problems solved by technology

The currently used transparent electrode material is mainly indium tin oxide (ITO), and ITO is usually prepared by sputtering. If the sputtering power is too high, it will damage the organic light-emitting layer of the OLED. If the sputtering power is too low, the film formation time will be reduced. Too long, mass production capacity is very low

Abstract

The invention provides a transparent OLED display and a manufacturing method thereof. In the manufacturing method of the transparent OLED display of the present invention, by preparing the cathode and the anode on two different substrates, the damage to the light-emitting layer made of organic light-emitting materials is effectively avoided when sputtering the top anode of the OLED, and the product quality is improved. efficiency; by using transparent conductive metal oxides to make the cathode and anode of OLED devices, it effectively solves the problem of high conductivity and high transparency electrode materials required for making transparent OLED displays; in addition, the upper and lower substrates can be produced at the same time during the production process, Then carry out pair pressing, which greatly improves the production efficiency. The transparent OLED display of the invention is easy to process and manufacture, and has good product performance.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a transparent OLED display and a manufacturing method thereof. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display, also known as organic electroluminescent display, is a new type of flat panel display device, due to its simple preparation process, low cost, low power consumption, high luminance, Wide range of working temperature, light and thin size, fast response speed, easy to realize color display and large-screen display, easy to realize matching with integrated circuit driver, easy to realize flexible display, etc., so it has broad application prospects. [0003] According to the driving method, OLED can be divided into two categories: passive matrix OLED (Passive Matrix OLED, PMOLED) and active matrix OLED (Active Matrix OLED, AMOLED), namely direct addressing and thin film transistor matrix addressing. Among them, AMOL...
