Abstract
Provided is a pixel integrate scanning (PIS) distributed type automatic power-saving electronic display board, which histogram-equalizes a reference value of color values of an initial image signal on the basis of image pulses along with the drive control for easily implementing a high-definition image to set the value of a current (If) supplied to and flowing through the LED, and allows the gain controller to compare the set current value with a difference between the image reference value of the gamma controller and the correction value of the histogram-equalized image and determine a change in a subtraction loss value based on the power consumption difference of a display image in consideration of image quality change, brightness, and image size to designate a current value for display on the electronic display board and transmit corresponding image information so that the power-saving operation of the LED module is automatically performed.
