Abstract: A discrete LED display control includes a method of scaling the brightness of frames of an image according to corresponding electrical current requirements. The method includes opening an electronic file containing a frame of an image to be shown on the display and measuring a commanded brightness for each pixel of the frame of the image. Brightness values of the commanded brightnesses are summed and converted to corresponding current values. The corresponding current values are adjusted to arrive at a total estimated current for the frame of the image. If the total estimated current exceeds a current limit of the display, the brightness value of each pixel is scaled to a final brightness value. The final brightness value corresponds to an adjusted current that is within the current limit. The adjusted current that corresponds to the final brightness value is sent to the display.
