| description | According to the present invention, provided is an operating method of a display driving chip, which includes the steps of: determining whether to change a level of a logic voltage supplied to a logic circuit of a display driving chip; transmitting a logic voltage setting command to a power management chip, when a level of the logic voltage needs to be changed; and receiving the logic voltage with a changed level corresponding to the logic voltage setting command from the power management chip. Therefore, power consumption can be reduced.
본 발명에 따른 디스플레이 구동 칩의 동작 방법은, 상기 디스플레이 구동 칩의 로직 회로에 제공되는 로직 전압의 레벨을 변경할 지를 판별하는 단계, 상기 로직 전압의 레벨 변경이 필요할 때, 대응하는 로직 전압 설정 커맨드를 전원 관리 칩으로 전송하는 단계, 및 상기 전원 관리 칩으로부터 상기 로직 전압 설정 커맨드에 대응하는 변경된 레벨을 갖는 로직 전압을 수신하는 단계를 포함할 수 있다. |
