    • 본 발명은 전계방출형 백라이트 장치를 개시한다. 이 백라이트 장치의 구동방식은 음극을 접지로 한 상태에서 게이트에 (+),(-)의 바이폴라(bipolar)형 펄스 전원을 인가한다. 펄스 전원은 일정 듀티 비를 가지며, 게이트에 (+)전압이 인가된 때에는 음극전극 상의 탄소나노튜브로 구성된 에미터로부터 게이트로 전자가 방출되고, (-)전압이 인가된 때에는 게이트 상부면의 탄소나노튜브로부터 음극전극으로 전자가 방출되도록 한다. 게이트 및 음극전극으로부터 전자가 양쪽에서 교대로 방출되는 동안 양극에 고전압을 인가하여 방출된 전자가 가속되게 하고 가속된 전자가 양극전극 상부면에 도포된 형광체를 때려서 발광시킨다. 본 발명은 음극 및 게이트 양쪽에서 교대로 전자가 방출되도록 하기 때문에, 전체 기판 면적중 에미터의 유효면적을 두배로 넓게하여 발광영역을 크게 하는 효과를 볼 수 있을 뿐만 아니라, 탄소나노튜브 에미터의 수명을 길게 해주고 면발광장치의 효율을 향상시킨다.
