Abstract

The invention provides a printing device and a frame encapsulating frit printing device, and belongs to the technical field of display panel preparation. The printing device can solve the problem thatan existing screen printing mask is easy to lose and short in life. The printing device is used for printing a frame encapsulating frit on a display substrate; the printing device comprises an accommodating chamber and an air pressure chamber, wherein the accommodating chamber comprises a main body part and a mask, the main body part is used for accommodating a frame encapsulating frit material;the mask is arranged on the side, close to the display substrate, of the main body part, and the mask is provided with a patterned opening area; and the air pressure chamber communicates with the accommodating chamber and is used for adjusting air pressure of the accommodating chamber so as to enable the frame encapsulating frit material in the accommodating chamber to be overflown through the opening area of the mask under the action of the air pressure.

Description

technical field

[0001] The invention belongs to the technical field of display panel preparation, and in particular relates to a printing device and a sealing glue printing device. Background technique

[0002] Currently, Organic Light-Emitting Diode (Organic Light-Emitting Diode;

[0003] One of the encapsulation methods adopted by OLED) display substrates is glass glue (frit) encapsulation. In this packaging method, a circle of glass glue is printed around the display area (edge) of the display substrate by screen printing to form a sealant pattern, and then the cover plate and the display substrate with the pattern of the sealant pattern are vacuum-boxed, and then The organic matter in the glass glue is removed by baking, and then the vacuum-bonded packaging substrate and the display substrate are bonded together by melting and bonding the glass glue through laser sintering. Specifically, in the prior art, the screen printing process uses a scraper to squeeze the mask, ...
