LED DISPLAY SYSTEM, LED DISPLAY CONTROL DEVICE, AND LED DISPLAY DEVICE

WIPO Patent Application WO/2022/029875

A1

Provided is a technology for making it possible to perform optimum power consumption control on each display area in an LED display system provided with an LED display control device and an LED display device. An LED display control device (200) is provided with a power supply area correction coefficient calculation part (40), a display area correction coefficient calculation part (41), and a video signal distribution part (32). The power supply area correction coefficient calculation part (40) calculates a correction coefficient for each power supply area. The display area correction coefficient calculation part (41) calculates a correction coefficient for each display area. The video signal distribution part (32) distributes a video signal and the correction coefficient calculated for each display area, to a plurality of cell LED units (100). Each of the cell LED units (100) is provided with a plurality of LEDs (1), a brightness adjustment part (5), and an LED driving part (6). The brightness adjustment part (5) adjusts the brightness of the video signal on the basis of the distributed correction coefficient. The LED driving part (6) drives the plurality of LEDs (1) on the basis of the video signal in which the brightness has been adjusted.
