摘要： An encapsulation structure, a display panel, an electronic device and an encapsulation method are provided. The encapsulation structure includes: a first substrate and a second substrate, and a first sealant and a second sealant bonding the first substrate and the second substrate to each other. The first sealant includes a first inclined surface; the second sealant includes a second inclined surface which is attached to and in direct contact with the first inclined surface. In a direction parallel to the first substrate, each of the first inclined surface and the second inclined surface extends from a first position to a second position. Along a direction from the first position to the second position, a distance from the first inclined surface to the first substrate and a distance from the second inclined surface to the second substrate gradually change; and sums of the two distances are substantially equal.

摘要： Provided are a pixel circuit, a display apparatus and a driving method. In one type of pixel circuit, a first switch transistor is arranged between a gate electrode of a driving transistor and a second electrode of a first reset transistor, such that a leak current of the first reset transistor has a relatively small influence on a gate signal of the driving transistor. In other types of pixel circuit, a second reset transistor for short-circuiting the gate electrode and a first electrode is provided, such that the resetting of an anode of a light-emitting device is only related to a signal of a second reset signal end. Therefore, the voltage difference between two ends of a third reset transistor can be reduced by means of adjusting a signal voltage of a reference voltage signal end.
