Problems solved by technology

[0004] However, the adhesion between the metal back cover and the glass substrate is poor, and after heating, the expansion degree of the metal back cover is larger than that of the glass substrate, which will cause stress problems
In addition, when the metal back cover is made into a large area, not only the cost is high, but also the problem of deformation will occur
Furthermore, after the traditional glass back cover is sandblasted to form grooves, the strength of the glass is weakened a lot

Embodiment Construction

[0033] The present invention proposes an organic electro-luminescent display (Organic Electro-Luminescent Display, OELD), which includes a display substrate and a back cover, and the back cover is assembled on the display substrate. The back cover is made of tempered glass, which can greatly increase the strength of the back cover and effectively prevent the fragments from falling. Hereinafter, an organic electroluminescent display and its packaging method are taken as an example to describe in detail. However, this embodiment is only an implementation mode under the inventive spirit of the present invention, and does not limit the protection scope of the present invention.

[0034] Please refer to figure 1 , which shows a graph according to a preferred embodiment of the present invention. The Organic Electro-Luminescent Display (OELD) 100 of this embodiment includes a display substrate 110 , a back cover 120 , a desiccant 130 and an adhesive.

[0035] The display substrate ...

Abstract

An organic electroluminance display includes a display base plate and a back cover-an intensified glass assembled in side display plate. The content of K ions in the back cover is larger than 1%, that is 3%~10%. A package method includes: providing a display base plate, and an intensified glass as the back cover, which is back-to-back with the display base plate.

Description

technical field [0001] The invention relates to an organic electroluminescent display, in particular to an organic electroluminescent display which applies tempered glass to a back cover. Background technique [0002] In recent years, Organic Light-Emitting Display (OLED) has gradually attracted attention in the display market due to its simple structure, excellent operating temperature and response speed, sharp color contrast, and no viewing angle limitation. [0003] The organic light-emitting materials and metal electrodes in the OLED are easy to interact with the moisture in the air, which will affect the display quality of the OLED and even shorten the service life. Traditionally, the method of adding desiccant is used to improve the above problems. In practice, after the desiccant is installed on the back cover with the groove, the back cover is combined with the OLED glass substrate to complete the OLED assembly. At present, there are two commonly used materials for...
