Abstract
There is provided a detection circuit, a display panel and a detection method. The detection circuit includes: a conversion circuit configured to acquire a photoelectric sensing signal in real time and convert the acquired photoelectric sensing signal into a luminance value; a storage circuit configured to store N luminance values from the conversion circuit on a first input first output basis; a discrimination circuit connected to the storage circuit and configured to determine whether at least two of the N luminance values meet a preset condition; and an output circuit connected to the discrimination circuit and the storage circuit, and configured to output a preset default luminance value in response to the at least two luminance values meeting the preset condition and output at least one of the N luminance values in response to the at least two luminance values not meeting the preset condition.
