Abstract

The invention provides an organic light-emitting diode and a preparation method thereof. According to the invention, the packaging is performed on the surface of a light-emitting layer, so the processis simple, the light-emitting layer can be effectively protected, the activity of the light-emitting layer material is prevented from being reduced due to corrosion caused by water and oxygen invasion, and the service life of the organic light-emitting diode is effectively prolonged. The problems that in the prior art, an organic light-emitting device is poor in packaging effect, complex in preparation procedure and the like are solved.

Description

technical field [0001] The invention relates to the display field, in particular to an organic light emitting diode and a preparation method thereof. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) is an emerging flat panel display technology. OLED display technology is different from traditional LCD display methods. It does not require a backlight and uses very thin organic material coatings and glass substrate layers. When an electric current passes through, these organic materials will emit light. Because of its simple preparation process, low cost, low power consumption, high luminous brightness, wide range of working temperature, light and thin volume, fast response speed, easy to realize color display and large screen display, easy to realize and match with integrated circuit driver, It is easy to realize the advantages of flexible display, so it has broad application prospects. [0003] Under the action of an external ...
