Abstract

본 발명은 프로젝션 TV에 관한 것으로서, 특히 램프를 효율적으로 사용하는 프로젝션 TV의 램프전원 제어방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a projection TV, and more particularly, to a lamp power control method of a projection TV that efficiently uses a lamp.

프로젝션 TV의 램프전원 제어방법은 전원 스위치를 온하였을 때 램프가 정상적으로 동작하는가를 확인하는 과정; 상기 확인과정에서 정상적으로 동작되지 않으며 소정의 시간 경과 후 자동으로 램프를 방전시켜 발광시키는 과정; 상기 램프가 정상동작하면 소정의 시간 후 리모콘 키입력 신호가 유입되는지 확인하는 과정; 및 상기 키입력신호가 유입되면 램프를 온 상태로 유지하고 상기 키입력신호가 유입되지 않으면 전원을 오프하여 램프를 오프시키는 과정을 포함함을 특징으로 한다.A method of controlling a lamp power supply of a projection TV includes the steps of checking whether a lamp operates normally when a power switch is turned on; A step of discharging the lamp by automatically discharging the lamp after a lapse of a predetermined period of time; Checking whether a remote control key input signal is inputted after a predetermined time when the lamp operates normally; And maintaining the lamp in an ON state when the key input signal is input, and turning off the lamp when the key input signal is not supplied, thereby turning off the lamp.

본 발명에 따른 프로젝션 TV의 램프전원 제어방법은 전원 온시에 램프가 소정의 기간동안 작동되지 않아 사용자가 TV를 더 이상 시청하지 않을 경우, 전원을 오프시켜 램프를 오프 상태로 함으로써, 램프가 비효율적으로 사용되는 것을 방지한다.The lamp power control method of a projection TV according to the present invention is characterized in that when the user does not watch TV any more because the lamp is not operated for a predetermined period of time at power on, To be used.
