Encapsulation material, display panel, and encapsulation method thereof

A display panel, comprising:

• a substrate;
• a thin film transistor layer being disposed on one surface of the substrate;
• a light-emitting layer being disposed on one surface of the thin film transistor layer away from the substrate, and the light-emitting layer comprising at least two light-emitting units disposed at intervals;
• and
• a first encapsulation layer being disposed on the light-emitting layer and filling a gap between two adjacent ones of the light-emitting units;
• wherein the first encapsulation layer is made of an encapsulation material, the encapsulation material comprises by mass percentage:
• a main resin, 20%-50%;
• a dilute monomer, 20%-50%;
• a stabilizer, 0.01%-2%;
• a microgel, 1%-10%;
• a chain transfer agent, 0.01%-5%;
• and
• an initiator, in a remaining percentage balance;
• wherein the chain transfer agent comprises ester activated vinyl sulfonate, and a molecular structure formula of the ester activated vinyl sulfonate is:
