Abstract

The present invention provides a double-sided OLED packaging structure, which includes an upper plate and a lower plate. A bending structure is arranged on the edge of the upper plate and the lower plate, and an encapsulating glue is arranged inside the bending structure, so that the first base, The side parts of the second base are correspondingly connected to the bending structure through the encapsulation glue; the beneficial effect is: in the double-sided OLED encapsulation structure of the present invention, the encapsulation glue is arranged on the side of the encapsulation cover, away from the light-emitting surface, thereby protecting the organic light emitting Layers are protected from high temperature damage to extend display life; the sides of the package lid can be thinned to help reduce the bezel width of double-sided displays.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a double-sided OLED display and a packaging method thereof. Background technique [0002] Organic Light Emitting Diode (OLED) displays are becoming more common, most notably in products such as mobile phones, media players and small entry-level TVs; It has the advantages of wide viewing angle, fast response speed, and flexible preparation; at the same time, when OLED devices work, electrons are injected from the cathode, which requires that the cathode work function be as low as possible, but these metals used as cathodes such as aluminum, magnesium, and calcium etc., are generally live waves, and are easy to react with the infiltrated water vapor, thereby affecting the working life of the OLED device. Therefore, the OLED device needs to be packaged during production to avoid entering water vapor. [0003] With the diversification of electronic products, double-sided display ha...
