Description
Technical field
The present embodiments relate to display technology more particularly to a kind of display panel and its packaging methods.
Background technique
Organic light emitting display panel (OLED) is the display panel of a new generation, is increasingly used by people.But by
Luminous organic material is more sensitive to the water oxygen in air in OLED, its corresponding encapsulation requires also very high.It mainly adopts at present
It is sealed with glass cement (Frit) material to achieve the purpose that effectively to obstruct water oxygen, usually using the mode of wire mark by glass
Glass glue material is coated on display panel.Wherein, wire mark (i.e. silk-screen printing) is the main printing side of one of porous printing art
Method, printing plate in netted, bite from space of a whole page throughhole portions to stock under the extruding of sdueegee by ink when printing on printing plate.
The plate-making of wire mark, printing technology are fairly simple, and required cost of equipment is few.
During practical wire mark, in the case where the height of glass cement and width meet the requirements, cross-section morphology is not
Ideal rectangle, due to the effect by halftone frictional force, glass cement pattern shows both sides protrusion and comes and under middle concave after wire mark
The shape (M shape) gone.After sintering furnace toasts, the organic solvent in glass cement volatilizees, and the bimodal aggravation in section easily causes back segment to swash
When light is sintered, substrate does not have enough glass cements to fill with cover board intermediate region, there is gap between glass cement and substrate, causes
Glass cement and substrate cannot completely attach to, and easily cause package failure.
