Disclosed are a head-up display device for a vehicle and a control method thereof. According to an embodiment of the present invention, the head-up display device for a vehicle comprises: a display panel configured to receive an optical signal and output an image; a guide housing having one side on which the display panel is fixated and having an air circulation path configured such that the internal air can circulate along an inner circumferential surface; a backlight unit fixated inside the guide housing and configured to emit light toward the display panel; a blowing fan for forced convection of the internal air along the air circulation path; and a heat exchange unit configured such that internal air of the guide housing can exchange heat with ambient air. The present invention enhances the durability and reliability.
차량용 헤드업 디스플레이 장치 및 그 제어방법을 개시한다. 본 개시의 일 실시예에 의하면, 광신호(optical signal)를 전달받아 영상을 출력하도록 구성된 디스플레이 패널(display panel); 일측에 상기 디스플레이 패널을 고정시키고, 내부둘레면(inner circumferential surface)을 따라 내부공기(internal air)가 순환할 수 있도록 구성된 공기순환로(air circulation path)를 구비한 가이드 하우징(guide housing); 상기 가이드 하우징의 내부에 고정되어 상기 디스플레이 패널을 향해 빛을 방출하도록 구성된 백라이트 유닛(backlight unit); 상기 공기순환로를 따라 상기 내부공기를 강제 대류(forced convection)시키기 위한 송풍팬(blowing fan); 및 상기 가이드 하우징의 내부공기가 외기(ambient air)와 열교환할 수 있도록 구성된 열교환부(heat exchange unit)를 포함하는 것을 특징으로 하는 차량용 헤드업 디스플레이 장치를 제공한다.
