Problems solved by technology

[0003] Since OLED is a self-illuminating device, light is emitted from various angles, causing the light to diffuse from this pixel to other adjacent pixels, resulting in mixed light, uneven light emission, low brightness and other phenomena that affect the display effect.

Abstract

The invention discloses an OLED packaging structure and a preparation method thereof. The packaging structure comprises a substrate and an anode layer arranged on the substrate, the packaging structure further comprises an OLED layer, an ALD film layer, a first nitrogen-silicon compound layer, a PMMA layer, a second nitrogen-silicon compound layer, an insulating filtering assembly layer and a glass cover plate which are sequentially arranged on the anode layer from bottom to top. An annular hole cavity penetrating through the ALD film layer, the first nitrogen-silicon compound layer and the PMMA layer is formed in the packaging structure, and a reflecting film layer is arranged in the annular hole cavity. According to the invention, the phenomena of light mixing, non-uniform light emitting, low brightness and the like caused by a fact that light rays are not diffused to adjacent sub-pixels can be controlled.

Description

Technical field [0001] The invention belongs to the field of OLED display, and specifically relates to an OLED packaging structure and a preparation method thereof. Background technique [0002] OLED (Organic Light Emitting Display) is known as the dark horse of the next-generation display technology. It has been widely used in the fields of electronic products, commercial fields, transportation, industrial control, and medical fields. In recent years, major international companies have In the continuous strengthening of OLED technology research, OLED technology will be further improved, OLED displays will usher in explosive growth. Since OLEDs are extremely sensitive to water, oxygen, and pollutants, it is necessary to use packaging. Nowadays, the packaging methods for OLED devices basically use TFE packaging, that is, ALD preparation is performed on the OLED layer, followed by SiNx preparation, and then inkjet printing (IJP) polymer (PMMA) on it, and then SiNx Preparation.
