Packaging method of organic electronic device

Abstract

The invention discloses a method for packaging an organic electronic device. The method for packaging the organic electronic device comprises the following steps that a plurality of layers of composite thin films are deposited on the back side of a lining material before the electronic device is prepared, the layers of composite thin films are deposited on the surface of the organic electronic device after the electronic device is prepared. By the adoption of a chip scale packaging method, a packaging process is integrated to a device manufacturing technological process, and therefore the original method of firstly manufacturing the device on a wafer and then the device is singly packaged after being cut is replaced. The method for packaging the organic electronic device has the advantages of improving efficiency and reducing cost. By the adoption of packaging through organic / inorganic layers of composite thin films in an innovative mode, water and oxygen can be isolated, therefore, the service life of the organic electronic device is greatly prolonged, flexible packaging can be achieved, and foldable and bending performance of the organic electronic device can be saved to the maximum. Eventually, according to the method for packaging the organic electronic device, low-temperature film formation below 120 DEG C is achieved, and heat damage to the device and plastic lining is reduced.

Description

Technical field [0001] The present invention relates to the field of electronic packaging, in particular to a packaging method for organic electronic devices. Background technique [0002] Organic optoelectronic devices have developed rapidly in the past two decades, especially organic light-emitting diodes (OLED), which have a series of advantages such as high luminous efficiency, low working voltage, lightness and flexibility, and their related technologies and industries have received extensive attention. At present, the annual output value of OLED displays exceeds one billion U.S. dollars, and the products involve TVs, MP3s, mobile phones, car audio, etc. OSRAM, GE, Philips and other traditional global lighting giants have invested heavily in the OLED lighting field and began to launch related products in 2009. According to the market analysis report of professional organization NanoMarkets, the OLED display and lighting market will reach 10.9 billion US dollars in 2012. Rea...

Problems solved by technology

[0005] The traditional rigid OLED and OPV device packaging is generally used in the glove box to cover the device with epoxy resin cured glass and other packaging covers, and combined with the use of dry film packaging, but the rigid packaging cannot meet the packaging requirements of flexible devices, and the flexible plastic substrate itself The water oxygen permeability is also higher than 10-5g / m 2 / day, which requires water and oxygen barrier isolation for flexible substrates
