Abstract
The present disclosure discloses a luminance compensation method, a luminance compensation circuit and a display device. When a display panel starts displaying, reference compensation factors are acquired from a flash. Then the acquired reference compensation factors are stored in and RAM. Finally, a scale factor corresponding to the current to-be-displayed frame image is acquired, and the reference compensation factors corresponding to all sub-pixels and stored in the RAM are multiplied by the scale factor to generate a target compensation factor corresponding to the current to-be-displayed frame image, to enable the display panel to perform the displaying according to the target compensation factor.
