Abstract
Disclosed are a display panel, a drive method therefor, and a display apparatus. By providing a light emergence angle adjustment structure () on a light emergence side of an organic light emitting device () and when an electric field is formed by applying different voltages on an electrode structure (), on one respect, an electrical control material layer () of the light emergence angle adjustment structure () forms a convex lens structure under the action of the electric field, and the convex lens structure has the effect of concentrating an outputted light; and an another respect, the electrical control material layer () forms a concave lens structure under the action of the electric field, and the concave lens structure has the effect of dispersing an outputted light.
