Problems solved by technology

In the prior art, organic or inorganic materials have been used to form a protective layer to surround a specific organic light emitting diode layer to resist the intrusion of harmful gas elements. Examples of such protective layers are disclosed in US Patent Nos. 6,268,695 and 6,570,325. However, these protective layers are usually only hundreds of nanometers (nanometer) thick, they can only provide a general degree of protection, can not achieve satisfactory efficacy

Abstract

A double-sided display device comprising two organic light-emitting diode display elements fabricated on two substrates, each substrate having a peripheral region surrounding its respective display element, absorbing elements placed on one or both of the peripheral regions, And it substantially surrounds two display elements to absorb harmful gas elements in the double-sided display device. The sealing material is coated along the peripheral areas of the two substrates to surround the absorbing element, so that the organic light-emitting diode display element can be completely sealed, and one or more absorbing layers can be placed between the first and second display elements to seal the The material has a thickness sufficient to leave an air gap between the first and second display elements.

Description

technical field [0001] The invention relates to an organic electroluminescence display element, in particular to an organic light emitting diode (OLED) and a polymer light emitting diode (PLED) display element, and a method for protecting a double-sided display device from harmful gas elements in the surrounding environment. Background technique [0002] Organic electroluminescent display elements, including polymer and small molecule organic light-emitting diodes, can be applied to display elements of various products, such as laptop computers, televisions, digital display electronic watches, telephones, portable pagers, In mobile phones, electronic calculators and similar products. Generally speaking, OLEDs have a simpler structure, and are easier and less expensive to manufacture than other display elements. A basic OLED display element consists of a flat, transparent substrate, and display elements fabricated on the substrate. [0003] Some product applications, such a...
