Double-sided display panel with special packaging structure

Abstract

The invention relates to a double-sided display panel with a special packaging structure, which comprises an OLED (Organic Light Emitting Diode) device, a substrate, a packaging cover plate arranged opposite to the substrate, wherein an accommodating groove formed in the surface, opposite to the substrate, of the packaging cover plate and used for packaging the OLED device; the surface, opposite to the substrate, of the packaging cover plate comprises a first convex part surrounding the accommodating groove and a second convex part surrounding the first convex part; the surface, opposite to the packaging cover plate, of the substrate is provided with a packaging glue groove matched with the first convex part and a drying agent groove matched with the second convex part. A packaging adhesive is arranged between the packaging adhesive groove and the first convex part, and a first drying agent is arranged between the drying agent groove and the second convex part; and the inner side of the packaging glue groove is provided with a whole circle of isolation groove. According to the double-sided display panel, the packaging adhesive groove and the first convex part are additionally arranged on the packaging cover plate and the substrate respectively, so that the contact surface of the double-sided display panel and packaging adhesive is increased, and the packaging strength is improved.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a double-sided display panel with a special packaging structure. Background technique [0002] Compared with the traditional TFT-LCD (thin film transistor-liquid crystal display, thin film transistor liquid crystal display) technology, OLED (Organic Light-Emitting Diode, organic electroluminescent device) has the advantage of being able to be made into a flexible device, and its application range is wider wide. According to the driving method, OLED can be divided into passive OLED and active OLED. Active OLEDs are driven by thin-film transistors, and each pixel is individually lit. It has the advantages of high brightness, high resolution, low power consumption, easy colorization, and large-area display. It is a commonly used method now. [0003] At present, the biggest problem restricting the development of the OLED industry is the short lifespan. The main reason ...

Problems solved by technology

[0003] At present, the biggest problem restricting the development of the OLED industry is the short lifespan. The main reason for the short lifespan of OLEDs is that the electrodes and light-emitting layer organic materials that make up OLED devices are very sensitive to pollutants, water vapor, and oxygen in the atmosphere. , Oxygen environment is prone to electrochemical corrosion, causing damage to OLED devices
