Method of encapsulating display substrate and counter substrate, encapsulated display panel, display apparatus, and counter substrate

An encapsulated display panel, comprising:

• a display substrate;
• a counter substrate facing the display substrate;
• and
• a sealant filled in a space between the display substrate and a counter substrate;
• wherein the display substrate in a peripheral area has a plurality of protruding parts and a plurality of recessing parts, resulting in an uneven surface topography;
• the counter substrate in at least a portion of the peripheral area has a counter surface topography substantially complementary to the surface topography of the display substrate, the counter substrate in the peripheral area has a plurality of counter protruding parts;
• the counter substrate in the peripheral area has a plurality of corner protrusions abutting a plurality of corners of the sealant frame, respectively;
• a respective one of the plurality of corner protrusions is in direct contact with the sealant frame;
• and
• the respective one of the plurality of corner protrusions protrudes into a recess having the sealant and the sealant frame as side walls.
