Abstract
A manufacturing method for OLED display panel is disclosed, which first performs patterning on the encapsulation colloid of the encapsulant to divide encapsulation colloid into a plurality of target encapsulation areas, with each target encapsulation area corresponding to each OLED substrate unit, and a gap area outside of target encapsulation areas, performing disintegration treatment from the other side of encapsulation colloid on a portion of encapsulation colloid belonging to gap area so that the surface losing adhesiveness, then attaches encapsulation colloid to OLED substrate, and finally, obtains a plurality of OLED display panels by cutting. This method is simple to perform, reduces the size compatibility requirement of the laminator and avoids the use of extra manipulator and carrier fixture, which reduces the product cost incurred by fixture cleaning, transport, storage and other complex operations, and improves the product of the alignment accuracy, is good for automated production.
