Abstract: Display panel, display device and detection compensation method of display panel are disclosed herein. In one embodiment, a display panel includes: display pixels arranged in M rows and N columns and provided in a display area, where both M and N are both positive integers; first power supply lines provided in the display area; and an integrated circuit, a switch circuit and a voltage stabilization transistor provided in a border area. One row of display pixels is electrically connected to one first power supply line. The first power supply lines are electrically connected to a first pin of the integrated circuit. A detection pin of the integrated circuit is electrically connected to the switch circuit. The voltage stabilization transistor includes: a control electrode electrically connected to the second pin, a first electrode electrically connected to the detection pin, and a second electrode electrically connected to one row of display pixels.

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.

Abstract: Provided is a method for determining a compensation grayscale value of a display panel. The method includes searching, in a table of grayscale bit number judgment values, for a grayscale bit number judgment value corresponding to a sub-pixel to be compensated; determining a compensation grayscale value corresponding to the sub-pixel to be compensated by a first reading process if the grayscale bit number judgment value satisfies a grayscale bit number condition, and determining the compensation grayscale value corresponding to the sub-pixel to be compensated by a second reading process if the grayscale bit number judgment value does not satisfy the grayscale bit number condition.
