Abstract

The invention relates to an OLED panel with a special packaging structure. The OLED panel comprises an OLED device, a substrate, and a packaging cover plate opposite to the substrate. An accommodationgroove is formed in the surface, opposite to the substrate, of the packaging cover plate and is used for packaging an OLED device. The surface, opposite to the substrate, of the packaging cover platecomprises 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 isprovided with a packaging glue groove matching the first convex part and a drying agent groove matching the second convex part. A packaging adhesive is arranged between the packaging glue groove and the first convex part, and a first drying agent is arranged between the drying agent groove and the second convex part; a buffer structure is arranged on the surface, located between the first convex part and the accommodation groove, of the packaging cover plate. According to the OLED panel, the packaging glue groove and the first convex part are additionally arranged on the packaging cover plateand the substrate respectively, so that the contact surface with the packaging glue 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 an OLED panel with a special encapsulation 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 for the sho...
