More Information
Summary:Provided is a driving method of an LED display device which determines an idle time corresponding to each of LED driving clocks by using the number of the LED driving clocks corresponding to one frame, controls to generate LED driving clocks based on the determined idle time, and drives an LED module by an LED line unit based on the generated LED driving clocks. The LED display device automatically adjusts an idle time corresponding to LED driving clocks to reduce flicker phenomena. 하나의 프레임에 대응하는 LED 구동 클럭들의 수를 이용하여 LED 구동 클럭들 각각에 대응하는 휴지 시간을 결정하고, 결정된 휴지 시간에 기초하여 LED 구동 클럭들을 생성하도록 제어하며, 생성된 LED 구동 클럭들에 기초하여, LED 모듈을 LED 라인 단위로 구동시키는 LED 디스플레이 장치의 구동 방법을 제공한다. LED 디스플레이 장치에서 자동적으로 LED 구동 클럭들에 대응하는 휴지 시간을 조정함으로써 플리커 현상을 저감할 수 있다.
