Brightness debugging method and device of display panel, computer equipment and storage medium

The invention relates to a brightness debugging method and device of a display panel, computer equipment, a storage medium and a computer program product. The method comprises the following steps: lightening a target screen according to a preset gray scale, and obtaining a first brightness difference between a first area and a second area in the target screen and a second brightness difference between a third area and the second area; generating an experiment image of the target screen according to the preset gray scale, the first brightness difference and the second brightness difference; determining a target experiment condition of the target screen according to the first brightness difference, a brightness attenuation curve of the first area and a preset experiment condition corresponding to the brightness attenuation curve; and under the condition that the target screen displays the experiment image, performing an experiment on the target screen according to the target experiment condition. The brightness
