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.

Pixel integrate scanning (PIS) distributed type automatic power-saving electronic display board

A four-way dual scanning electronic display board capable of scan control, whereby, in order to provide drive control, an LED module arrangement method, and processing for each LED pixel dot (R, G, B), which are for easily enabling a high definition image, pixel display dots of an LED module are controlled by processing image display dots of the module by means of a four-way method by an automatic image switching device through the display control of SCU image switching, in order to display a high definition image through the four-way control of each image dot (R, G, B) pixel, and thus high resolution image quality may be enabled and displayed.
