Abstract: A method for improving a halo is applied to a display panel. The display panel includes a dimming sub-panel and a display sub-panel that are superposed. The dimming sub-panel includes a plurality of first pixels, the display sub-panel includes a plurality of second pixels, and each first pixel corresponds to at least two second pixels. The method for improving the halo includes: as for the first pixel: acquiring a second brightness datum of each of the at least two second pixels corresponding to the first pixel; calculating a target brightness datum of the first pixel according to second brightness data of the at least two second pixels; determining a first gray-scale datum of the first pixel according to the target brightness datum.
