Abstract
The present disclosure discloses a control method and a control apparatus for brightness of display panel, a storage medium and a processor. The method comprises: acquiring a plurality of pixel values processed by an image processor, wherein the bit width of each of the plurality of pixel values is a first preset bit width; performing data type conversion on each pixel value to obtain a plurality of pixel values of a second preset bit width, wherein the second preset bit width is greater than the first preset bit width; sending the plurality of pixel values of the second preset bit width to a digital-to-analog conversion module to determine the voltage output value of each sub-pixel of a display panel, wherein the voltage output value has a first linear relationship with the screen brightness of the display panel; and adjusting the voltage output value to control the screen brightness of the display panel.
