Description
一種顯示裝置,尤其是指一種小型模組化且安裝簡易之可攜式抬頭顯示裝置。A display device, in particular, a portable head-up display device that is small in modularization and simple to install.
在一駕駛環境中,駕駛者需要隨時接收車速、水溫、引擎轉速、檔位及油量等各種訊息,例如在汽車的駕駛艙中,係以儀表板顯示前述訊息,而儀表板通常配合車體之設計,設置於擋風玻璃下方。In a driving environment, the driver needs to receive various information such as speed, water temperature, engine speed, gear position and fuel quantity at any time. For example, in the cockpit of a car, the above message is displayed on the dashboard, and the dashboard is usually matched with the vehicle. The body is designed to be placed under the windshield.
駕駛者在駕駛過程中,需透過擋風玻璃掌握周遭環境路況的變化。然而,人類肉眼的視野有限,因此,在透過擋風玻璃觀察周遭路況的同時,仍需移轉視線至設置於擋風玻璃下方之儀表板觀看車速等訊息,此視線的移轉往往造成駕駛者瞬間的分心,導致駕駛危安事故的發生。During the driving process, the driver needs to grasp the changes of the surrounding environmental conditions through the windshield. However, the human eye has limited vision. Therefore, while observing the surrounding road conditions through the windshield, it is still necessary to shift the line of sight to the dashboard set under the windshield to watch the speed of the vehicle. The shift of the line of sight often causes the driver to The momentary distraction caused the driving accident to occur.
為了解決上述問題,乃有抬頭顯示裝置(Head-Up Display Device,HUD)的出現。顧名思義,抬頭顯示裝置的功能在於讓駕駛者在不需低頭觀看儀表板的情況下,亦能得知車速、油量等訊息。In order to solve the above problems, there is a emergence of a Head-Up Display Device (HUD). As the name implies, the function of the head-up display device is to allow the driver to know the speed, the amount of fuel, etc. without having to look down at the dashboard.
習知抬頭顯示裝置有多種不同形式,其一為在擋風 玻璃下方設置一LED顯示盒,再透過設置於擋風玻璃上的反射膜反射LED顯示盒之訊息至駕駛者。然而,此種形式的抬頭顯示裝置,其影像未經放大,使得影像過小,且影像聚焦點距離擋風玻璃過近,使駕駛者仍然需作視野轉移的動作方能得到所需訊息,也因此無法完全發揮抬頭顯示裝置的效果。Conventional head-up display devices come in many different forms, one of which is in the wind An LED display box is arranged under the glass, and the signal of the LED display box is reflected to the driver through the reflective film disposed on the windshield. However, in this form of head-up display device, the image is not enlarged, so that the image is too small, and the image focus point is too close to the windshield, so that the driver still needs to perform the action of the field of view to obtain the desired message, and thus The effect of the head-up display unit cannot be fully utilized.
另外一種形式的抬頭顯示裝置,在LED或LCD等顯示器之前設置一放大鏡組,再將放大後的影像透過光學系統反射至駕駛者。然而,此種形式的抬頭顯示裝置需設置複雜的光學系統以解決色像差及影像歪曲等問題,造成整個抬頭顯示裝置體積過於龐大,並且其光學系統需與車廠搭配在造車時即需設置,導致建置成本過大。再者,在周遭環境光太強的狀況下,此種抬頭顯示裝置所呈現的影像容易有對比或亮度不足而致辯識不清的問題。Another form of head-up display device provides a magnifying glass set in front of a display such as an LED or LCD, and then reflects the magnified image through the optical system to the driver. However, this type of head-up display device requires a complicated optical system to solve problems such as chromatic aberration and image distortion, resulting in an oversized bulk display device, and the optical system needs to be matched with the vehicle manufacturer to be set when the vehicle is built. The cost of construction is too large. Moreover, under the situation that the ambient light is too strong, the image presented by such a head-up display device is easy to be confused or the brightness is insufficient to identify the problem.

The portable head-up display device 100 includes a micro-projector 101, an optical path guiding module 106, and an adjustable display panel 105.
微投影機101係作為一影像源。微投影機101可為一數位光學處理微投影機、一矽基液晶微投影機、一液晶微投影機或一掃描式雷射投影機。微投影機101內包含接收模組101a,可接收訊息,並將訊息投影而出。接收模組101a可為一有線接收模組或無線接收模組。透過接收模組101a,微投影機101更可與智慧型手機、GPS導航裝置、可攜式電腦等作連結,將各式訊息投影而出。The micro projector 101 serves as an image source. The micro projector 101 can be a digital optical processing micro projector, a silicon based liquid crystal micro projector, a liquid crystal micro projector or a scanning laser projector. The micro projector 101 includes a receiving module 101a that can receive a message and project the message. The receiving module 101a can be a wired receiving module or a wireless receiving module. Through the receiving module 101a, the micro projector 101 can be connected with a smart phone, a GPS navigation device, a portable computer, etc., and various types of messages can be projected out.
光路導引模組106接收微投影機101投射過來的影像,其內設置有若干光學元件,使影像透過光路導引模組106投影而出。光路導引模組106內設置有一光擴散板102、一反射裝置103以及一光學鏡頭模組104。光路導引模組106之設計,主要為形成模組化,將除微投影機101及可調式顯示板105外的光學元件收納集合,以達到小型可攜的效果。為達到小型可攜效果,光擴散板102與微投影機101之距離介於1至5公分,反射裝置103與光擴散板102之距離介於3至7公分,而光學鏡頭模組104與反 射裝置103之距離介於3至7公分。藉由光路的最佳化設計,使光路導引模組106能達到小型化而不減損光學效果。另一方面,影像的色像差或歪曲等誤差,藉由光學鏡頭模組104即可消除,之後的可調式顯示板105可使用塑膠或玻璃材質的透明平板,不必如習知為消除色像差而使用具弧度之顯示板,易導致疊影或影像形狀失真等狀況發生。The optical path guiding module 106 receives the image projected by the micro projector 101, and has a plurality of optical elements disposed therein to project the image through the optical path guiding module 106. A light diffusing plate 102, a reflecting device 103 and an optical lens module 104 are disposed in the optical path guiding module 106. The optical path guiding module 106 is mainly designed to be modularized, and the optical components except the micro projector 101 and the adjustable display panel 105 are collected and assembled to achieve a small portable effect. In order to achieve the small portable effect, the distance between the light diffusing plate 102 and the micro projector 101 is between 1 and 5 cm, the distance between the reflecting device 103 and the light diffusing plate 102 is between 3 and 7 cm, and the optical lens module 104 and the opposite The distance of the launching device 103 is between 3 and 7 cm. By optimizing the design of the optical path, the optical path guiding module 106 can be miniaturized without detracting from the optical effect. On the other hand, errors such as chromatic aberration or distortion of the image can be eliminated by the optical lens module 104. The adjustable display panel 105 can be a transparent plate made of plastic or glass, which is not necessary to eliminate the color image. Poor use of a curved display panel can easily lead to situations such as aliasing or image shape distortion.
光擴散板102的設置,使由微投影機101投影而出的影像經過光擴散板102後的亮度分佈更為均勻,具有增加對比及亮度的效果。光擴散板102並具有可切換的一高穿透率部102b及一低穿透率部102c,藉此可依需求切換不同的穿透率,可令最終的影像亮度隨不同外在環境背景亮度得到適當的調整。光擴散板102至少一表面可形成規則或不規則之凹凸形狀102a。在一實施例中,凹凸形狀102a由一微鏡陣列組成。微投影機101投影而出的影像的光線,在透過光擴散板102後,為凹凸形狀102a打散並重分配,使亮度分佈更為均勻;並且透過凹凸形狀102a形成光學折射及反射等效應,使重分配後之光線更為集中,因此可增加影像的亮度及對比,降低周遭環境強光的影響。The arrangement of the light diffusing plate 102 makes the brightness distribution of the image projected by the micro projector 101 through the light diffusing plate 102 more uniform, and has the effect of increasing contrast and brightness. The light diffusing plate 102 has a switchable high transmittance portion 102b and a low transmittance portion 102c, so that different transmittances can be switched according to requirements, and the final image brightness can be adjusted with different external environment background brightness. Get the appropriate adjustments. At least one surface of the light diffusing plate 102 may form a regular or irregular concave-convex shape 102a. In one embodiment, the relief shape 102a is comprised of a micro mirror array. The light of the image projected by the micro projector 101 is scattered and redistributed by the uneven shape 102a after passing through the light diffusing plate 102 to make the brightness distribution more uniform, and the effects of optical refraction and reflection are formed through the uneven shape 102a. The light after redistribution is more concentrated, so it can increase the brightness and contrast of the image and reduce the influence of ambient light.
反射裝置103改變光路徑,使影像能投射至光學鏡頭模組104。反射裝置103可使用任何可改變光路徑的光學元件,例如反射鏡、分光片、偏振分光片、菱鏡或全像光學件等。The reflecting device 103 changes the light path so that the image can be projected onto the optical lens module 104. The reflecting means 103 can use any optical element that can change the light path, such as a mirror, a beam splitter, a polarizing beam splitter, a prism or a holographic optic, and the like.
光學鏡頭模組104包含至少一片鏡片。目的在接收透過反射裝置103反射而來的影像(此時為實像),將其轉化 為虛像S並且放大。光學鏡頭模組104可使用二片以上的鏡片,鏡片可為一雙凸透鏡、一雙凹透鏡、一平凸透鏡、一平凹透鏡、一全像光學件,一平面鏡、一繞射光學件或一菲涅爾透鏡的任意組合,而透過不同鏡片的組合,能對影像之色像差或歪曲作一校正,使影像能清楚正確地呈現。The optical lens module 104 includes at least one lens. The purpose is to receive an image reflected by the reflecting device 103 (in this case, a real image), and convert it into It is a virtual image S and is enlarged. The optical lens module 104 can use two or more lenses, and the lens can be a lenticular lens, a double concave lens, a plano-convex lens, a plano-concave lens, a holographic optical element, a plane mirror, a diffractive optic or a Fresnel lens. Any combination of the different lenses can be used to correct the chromatic aberration or distortion of the image so that the image can be clearly and correctly presented.
