Abstract
The present invention provides a brightness compensation method, a system and a display panel in a Demura system. The method comprises obtaining an included angle θ between a connection line of a pixel dot and a center point of a camera lens and a horizontal line as a camera is fixed; obtaining a brightness value f(θ) corresponding to the θ according to a pre-stored angle-brightness relationship; obtaining a correction brightness value of the pixel dot according to a calculation of the f(θ) and a default formula, and performing brightness compensation to the display panel according to the brightness value of the pixel dot after correction. The technical solution provided by the present invention can reduce the influence of the view angle to the brightness and the influence of cosθ to the brightness, and thus, it possesses the benefit of the brightness decay offset reduction.
