Abstract
A brightness adjustment method, a brightness adjustment device and a display device are provided. The brightness adjustment method includes: dividing into M first regions in accordance with a distribution state of common voltages V, a difference between the common voltages Vin different first regions being greater than a first threshold; dividing into N second regions in accordance with a distribution state of pixel voltages V, a difference between the pixel voltages Vin different second regions being greater than a second threshold; calculating a voltage compensation value in each first region; calculating a voltage compensation value in each second region; overlapping the M first regions and the N second regions to obtain M*N adjustment regions; calculating gamma voltages at different grayscales in each adjustment region to obtain a set of gamma data about the M*N adjustment regions; driving a display module to display in accordance with the gamma data.
