Abstract
A device and a method for obtaining brightness of a display panel are provided. The display panel includes a flat area and a curved area and the curved areas including at least one first curved area. The device includes a brightness acquisition component; an optical path adjustment component; and a control component. Principle light exited from the flat area is incident on a first area of a viewfinder plane of the brightness acquisition component; the optical path adjustment component is disposed on an optical path of principle light exited from the first curved area, and configured to adjust the principle light to be incident on a second area of the viewfinder plane; the first area does not overlap with and the second area; and the control component is configured to process an image captured by the brightness acquisition component to obtain the brightness of the display panel.
