| description | An objective of the present invention is to provide a method of driving an LED backlight unit which can realize performance improvement and power reduction. The method of driving an LED backlight unit including a plurality of LED devices connected to a plurality of source lines and a plurality of gate lines generates a plurality of gate signals applied to the plurality of gate lines. While generating the plurality of gate signals, a non-overlapping section, in which the plurality of gate signals are all inactivated, is generated between active sections of two adjacent gate signals. A plurality of source signals applied to the plurality of source lines are generated. While generating the plurality of source signals, a high-impedance section allowing at least some of the plurality of source signals to have a high-impedance state and including the non-overlapping section is generated.
복수의 게이트 라인들 및 복수의 소스 라인들과 연결되는 복수의 LED 소자들을 포함하는 LED 백라이트 유닛의 구동 방법에서, 복수의 게이트 라인들에 인가되는 복수의 게이트 신호들을 생성한다. 복수의 게이트 신호들을 생성하면서, 인접한 2개의 게이트 신호들의 활성화 구간들 사이에 상기 복수의 게이트 신호들 모두가 비활성화되는 비중첩 구간을 생성한다. 복수의 소스 라인들에 인가되는 복수의 소스 신호들을 생성한다. 복수의 소스 신호들을 생성하면서, 복수의 소스 신호들 중 적어도 일부가 하이 임피던스 상태를 가지고 비중첩 구간에 포함되는 하이 임피던스 구간을 생성한다. |
