Description
本發明係有關於一種抬頭顯示器，特別指一種能有效減少佔用空間(體積)的抬頭顯示器，尤其適合使用在汽車上，將汽車行進間所需的各項資訊反射，以清晰的影像供予駕駛人讀取。The present invention relates to a head-up display, in particular to a head-up display capable of effectively reducing the space (volume), and is particularly suitable for use in a car, reflecting various information required for traveling between cars, and providing driving with clear images. People read.
抬頭顯示器(Head Up Display簡稱為HUD)係由一虛像投影系統的盒體(Box)及一光合成器(Combiner)所組成，早期是裝設於戰鬥機上，飛行員可經過光合成器同時觀看前方景物，以及由該裝置投射之虛像資訊而不必低頭察看儀表板，由於科技的不斷進步，汽車速度愈來愈快，提供行車所需相關的資訊也愈來愈多，這些資訊若一一顯示在傳統的儀表板上，駕駛人要察看前方的人、車、路面的狀況，又要挪動視線在顯示資訊的儀表板上，每一次的視線來回之間，總有時間差，在車速較快時，在專注於儀表板上的一或二秒鐘，在緊急狀況時，其實已足夠造成許多憾事，因此在汽車上裝設抬頭顯示器已漸漸漸成為一種近代潮流下的裝備。Head Up Display (HUD) is composed of a virtual projection system (Box) and a light combiner (Combiner). It was installed on the fighter aircraft at an early stage. The pilot can view the front scene through the optical synthesizer. As well as the virtual image information projected by the device, it is not necessary to look down at the dashboard. Due to the continuous advancement of technology, the speed of the car is getting faster and faster, and more and more information is needed to provide driving, and the information is displayed in the traditional one by one. On the dashboard, the driver should look at the situation of the person, the car, and the road ahead, and move the line of sight on the dashboard where the information is displayed. There is always a time difference between each line of sight. When the speed is fast, focus on One or two seconds on the dashboard, in an emergency, is enough to cause a lot of regrets, so the installation of a head-up display on the car has gradually become a device under the modern trend.
請參看第6圖所示，習用的抬頭顯示器80的盒體801(Box)內，包含有一顯像裝置81(即Imager)，可能是使用液晶面板(LCD panel)，由後方照明系統(圖中未示)將影像資訊射出，經過至少二道光學面鏡82,83，將資訊影像射向駕駛人前方的光合成器84，該光合成器84可能是汽車擋風 玻璃，或者是一個特殊設計的透明板片，使該資訊的影像510(虛像)能經反射後呈現，並被駕駛人的眼睛51所看見。Referring to FIG. 6, the box 801 (Box) of the conventional head-up display 80 includes a developing device 81 (ie, Imager), which may be a liquid crystal panel (LCD panel), and is illuminated by the rear (in the figure). The image information is emitted, and the information image is directed to the light combiner 84 in front of the driver through at least two optical mirrors 82, 83. The light combiner 84 may be a windshield of the automobile. The glass, or a specially designed transparent plate, allows the image 510 (virtual image) of the information to be reflected and rendered by the driver's eyes 51.
其中，由於抬頭顯示器80的盒體801(Box)，要把二維的影像以一定的視場角(F.O.V)投射出去，該抬頭顯示器80的盒體801就必需具有一定的體積，才可以藉由二光學面鏡82,83將二維的影像射向光合成器84，而要將此具有一定體積抬頭顯示器80的盒體801組設在汽車駕駛座前方有限的空間裡，就會變成十分困難，也阻礙了汽車上裝設抬頭顯示器的前景，此外，同時消除二個維度影像的像差非常困難，面鏡82,83必須是大面積的非球面(Aspherical Surface)或自由曲面(Free Form Surface)的面鏡，或再增設其他透鏡用來解決像差問題，如此則會增加零組件的製作成本，提高生產組裝的難度。也因此，目前在汽車上裝設抬頭顯示器的普及率一直無法達成，且成本過高，是習用的缺點。Wherein, due to the box 801 (Box) of the head-up display 80, the two-dimensional image is projected at a certain angle of view (FOV), and the box body 801 of the head-up display 80 must have a certain volume before borrowing The two-dimensional image is directed to the optical combiner 84 by the two optical mirrors 82, 83, and it is very difficult to assemble the box 801 having a certain volume of the head-up display 80 in a limited space in front of the driver's seat. It also hinders the prospect of installing a head-up display on a car. In addition, it is very difficult to eliminate the aberrations of two-dimensional images at the same time. The mirrors 82, 83 must be large-area aspherical surfaces or free-form surfaces (Free Form Surface). The mirror or other lens is added to solve the aberration problem, which will increase the manufacturing cost of the components and increase the difficulty of production assembly. Therefore, the current popularity of installing a head-up display on a car has not been achieved, and the cost is too high, which is a disadvantage of the conventional use.

本發明抬頭顯示器之結構，至少包含有：The structure of the head-up display of the present invention comprises at least:
一光源組10，為綫性排列的LED，於前方可加設一集光功能的場鏡11(Field Lens)；該光源組10接收來自經影像處理系統60轉化後的各時序掃描綫的影像資訊，再以綫性排列中各個相對應的LED點光源發出光束投射出去，在第1,3圖中僅擇兩個LED點光源發出的光束L1,L1’為例而示意之。A light source group 10 is a linear array of LEDs, and a field lens 11 (Field Lens) for collecting light is added in front; the light source group 10 receives images from the time series scan lines converted by the image processing system 60. The information is then projected by the corresponding LED point source in the linear arrangement. In the first and third figures, only the two LED point sources L1, L1' are illustrated as an example.
一聚光鏡組20，係設於光源組10的前方，用以聚焦成像。A concentrating lens assembly 20 is disposed in front of the light source group 10 for focusing imaging.
一掃描鏡30，係為一相對於光源組10的長形反射鏡，設於上述聚光鏡組20的前方，能將聚光鏡組20會聚後的光束L2,L2’掃描並反射至光合成器40，該掃描鏡30於兩端設有支軸31，為請細說明此一動作，請再參看第2-2,2-3,2-4圖所示，分別表示掃描鏡30在快速擺動時，鏡面與光束間的關係，但由於速度快速，因此可形成如第2-5圖所示，形成一整面的影像光束投射出去。A scanning mirror 30 is an elongated mirror with respect to the light source group 10, and is disposed in front of the concentrating mirror group 20, and can scan and reflect the light beams L2, L2' condensed by the concentrating lens assembly 20 to the optical combiner 40. The scanning mirror 30 is provided with a support shaft 31 at both ends. For the sake of detailed description of this action, please refer to Figures 2-2, 2-3, and 2-4, respectively, showing that the scanning mirror 30 is in a fast swing, the mirror surface The relationship with the beam, but due to the high speed, can form a full-face image beam as shown in Figure 2-5.
請參看第1、2、3圖所示，一光合成器40，係為一柱面曲率的半反射鏡，其反射率介於百分之十至百分之五十之間，用以反射由掃描鏡30射出的光束L2,L2’至駕駛人眼睛位置附近的可視範圍(Eye-Box)50，並由視線光束L3,L3’向後延伸而形成虛像成像點501,501’及綫形虛像502；該光合成器40置於駕駛人前方視綫的位置，利用其曲面設計及部分反射特性形成虛像，同時亦可利用其部分穿透特性使駕駛人得以透過該元件看清前方事物。Referring to Figures 1, 2 and 3, a light combiner 40 is a cylindrical mirror with a reflectivity between 10 and 50 percent for reflection. The light beam L2, L2' emitted by the scanning mirror 30 is to the visible range (Eye-Box) 50 near the driver's eye position, and is extended backward by the line of sight beams L3, L3' to form a virtual image forming point 501, 501' and a linear virtual image 502; The optical combiner 40 is placed at the position of the driver's front line of sight, and uses its curved surface design and partial reflection characteristics to form a virtual image. At the same time, it can also use its partial penetration characteristics to enable the driver to see things in front through the component.
一動力機構70，係接於掃描鏡30的支軸31上，再藉由控制單元71，能以該動力機構70將掃描鏡30進行往復角度的擺動，該擺動的範圍係以能將光束L2反射至光合成器40為範圍；惟該控制一物體作來 回擺動的動力機構70及控制單元71係取自習用即有的元件，並非本發明之重點，故該二結構即不予贅述。A power mechanism 70 is coupled to the support shaft 31 of the scanning mirror 30, and the control unit 71 can swing the scanning mirror 30 at a reciprocating angle by the power mechanism 70, and the swing range is such that the light beam L2 can be Reflecting to the optical combiner 40 is a range; but the control is an object The power mechanism 70 and the control unit 71 that are oscillated back are taken from the components that are conventionally used, and are not the focus of the present invention, so the two structures are not described herein.
因此，當光源組10將來自於影像處理系統60的資訊投射出影像中任一例點光束L1，經一聚光鏡組20聚光後射向掃描鏡30，該掃描鏡30受控制單元71及動力機構70而快速擺動，將會聚後的光束L2快速掃描並反射至光合成器40，再經光合成器40反射而在其外側形成一相對的虛像點501，且在內側駕駛人的可視範圍(Eye-Box)50內被看到；同理，在同一瞬間追跡光源組中所有LED點光源所發出光束至最終所形成的虛像點群，即可構成一綫形虛像502，該綫形虛像502如第3圖右側的箭頭所示，來回的投射，則集合本發明系統在各瞬間掃描所得的綫形虛像，即可形成清晰的二維虛像500。Therefore, when the light source group 10 projects the information from the image processing system 60 into any of the spot light beams L1 in the image, it is condensed by a concentrating lens group 20 and then directed to the scanning mirror 30, and the scanning mirror 30 is controlled by the control unit 71 and the power mechanism. 70 and swiftly oscillate, the concentrated beam L2 is quickly scanned and reflected to the optical combiner 40, and then reflected by the optical combiner 40 to form an opposite virtual image point 501 on the outside thereof, and the visible range of the inside driver (Eye-Box) ) is seen in 50; similarly, at the same instant, all the LED point light sources in the light source group are traced to the finally formed virtual image point group to form a linear virtual image 502, which is as shown in FIG. As shown by the arrow on the right side, the projection back and forth collects the linear virtual image obtained by scanning the system at each instant to form a clear two-dimensional virtual image 500.
請參看第2圖所示，在使用本發明時，由於本發明以綫性的光源組10射出光束L1，再由掃描鏡30進行往復角度的擺動，將光束L2反射至光合成器40，這樣的精巧構思，讓原本習用抬頭顯示器80(如第6圖所示)的大型立體盒體801立即改善成為如第2圖所示的扁長型盒體72，能減少因為視場角所造成的限制，更有利於組裝於汽車有限的駕駛位置，具有不佔空間的優點，同時便於推動汽車型的抬頭顯示器，為本發明之主要優點。Referring to FIG. 2, in the present invention, since the present invention emits the light beam L1 by the linear light source group 10, and then the reciprocating angle is swung by the scanning mirror 30, the light beam L2 is reflected to the optical combiner 40. Ingeniously conceived, the large stereo case 801 originally used for the head-up display 80 (shown in Fig. 6) is immediately improved to the elongate case 72 as shown in Fig. 2, which can reduce the limitation due to the angle of view. It is more advantageous to be assembled in a limited driving position of a car, has the advantage of not occupying space, and at the same time is convenient to promote an automobile-type head-up display, which is a main advantage of the present invention.
對於本發明之光源組10接收來自經影像處理系統60的影像資訊，是可以使用單色或彩色的LED來實施的，請參看第4-1圖所示，係為等距排列的LED 101,102,103呈一直綫排列而成的，可形成一單一綫性排列的光源組10；再請參看第4-2圖所示，係以重覆排列的紅綠藍三色 LED101R,101G,101B作出一列的綫性排列，則可藉由影像處理系統60來控制得到彩色的影像；再請參看第4-3圖所示，係分別各以一列紅綠藍三色的LED102R,102G,102B分別作出一列的綫性排列，亦可藉由影像處理系統60來控制得到彩色的影像；但不論是第4-1或4-2或4-3圖所示的LED101,1-2,103或101R,101G,101B或102R,102G,102B均可視為是形成一綫性的光束投射出去，以供如第1圖所示的掃描鏡30進行掃描及反射的動作。For the light source group 10 of the present invention, the image information received from the image processing system 60 can be implemented by using single or color LEDs. Please refer to Figure 4-1 for the LEDs 101, 102, 103 arranged equidistantly. Arranged in a straight line, a single linear array of light source groups 10 can be formed; see also Figure 4-2, which is arranged in red, green and blue colors. The LEDs 101R, 101G, and 101B are arranged in a linear array, and the image processing system 60 can be used to control the color image; for example, as shown in FIG. 4-3, the LEDs 102R are respectively arranged in a row of red, green and blue colors. , 102G, 102B respectively make a linear arrangement of columns, and the image processing system 60 can also be used to control the color image; however, the LED 101, shown in Figure 4-1 or 4-2 or 4-3, 1- 2, 103 or 101R, 101G, 101B or 102R, 102G, 102B can be regarded as forming a linear beam to be projected for scanning and reflection by the scanning mirror 30 as shown in Fig. 1.

A field lens 11 for collecting light may be added in front; the light source group 10 receives information from the image processing system 60, and can display the information in a time series scanning manner with the light beam L1.
