本發明之目的在提供一種可攜式抬頭顯示裝置。可攜式抬頭顯示裝置採用模組化設計,可簡易地設置於一汽車內,減少建置複雜度。可攜式抬頭顯示裝置使用微投影機為影像來源,並在微投影機投影出影像後先經過一光路導引模組。光路導引模組內包含一光擴散板或一毛玻璃,光擴散板或毛玻璃包含可切換之一高穿透率部及一低穿透率部。光擴散板藉由高穿透率部或低穿透率部接收影像,並隨一外部環境背景光之一亮度變化而調整影像之一亮度及對比。影像經由光學鏡頭模組由實像狀態轉化為虛像狀態後,透過一可調式顯示板呈現至駕駛者。可調式顯示板可隨不同擋風玻璃的傾斜角度及不同駕駛者的駕駛姿勢而變化,以達到最佳視角。 A portable head-up display device includes an image source, a light guiding module and an adjustable display panel. The light guiding module includes a light diffusor plate and an optical lens module. The light diffusor plate has a high transmittance portion and a low transmittance portion. The light diffusor plate is spaced a pre-determined distance from the image source for receiving an image, and adjusts a brightness and a contrast of the image with a variation of a brightness of an environmental background light. The optical lens module is space a pre-determined distance from the light diffusor plate for receiving the image from the light diffusor plate, and transforms the image form a real image state to a virtual image state. The adjustable display panel projects the image to a viewer. The adjustable display panel includes various tilting directions for coupling with various inclined angle of different windshields and various gesture of different drivers.
