Abstract:
A method of encapsulating a display substrate and a counter substrate, an encapsulated display panel, a display apparatus, and a counter substrate are provided. The encapsulated display panel includes 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. 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.
