Abstract
An electronic display board is configured to control 4-way dual scanning in which a gray scale pixel (GSP) is applied to a DICT, wherein an MCU, which is equipped with a GSP function along with driving control and DICT control for easily implementing a high-definition image, can switch, by dual scanning, an image in which an image data value with a gamma value determined on a histogram by (a gamma controller) of an image processing DICT unit including a GSP has been gray-scaled by the GSP to equalize and process the image through gamma correction of the image and the histogram of the brightness of the image, so that the image can be displayed on the electronic display board without noises such as interruption of the image and distortion of the image quality even under the control of image transmission for high-speed processing.
