Description of the invention (1) '---- [, technical field to which the invention belongs] The present invention relates to a refractive projection device, especially a refractive projection device suitable for a traffic carrier. [II. Prior technology] The head-up display device (head UP display) is used to project the important driving data 2 near the eyes and head up, so that the driver of the traffic vehicle (eg: steam :) during driving , Do not need to look down at the dashboard to see the magic square X Tong-like; brother, reduce the possibility of accidents. It has been widely used in automobiles and airplanes. The conventional head-up display device is placed in the space above the instrument panel, and is shot on the windshield of the parent vehicle to form a real image. However, if the real image of the f projection stroke is directly affected by external light. Especially during the day, the incidence of sunlight often causes insufficient contrast of the image projected by the head-up display device, making it difficult for the user to recognize the information displayed by the head-up display device. In addition, the traditional projection device forms a display device that projects a real image in the eyes. When the user ’s head is moved (for example, when a car is moving), the temple will produce blurred or severely shaken images caused by ghosting and Doppler effects. Poor quality. [III.

Please refer to FIG. 1, which is a schematic diagram of a first embodiment of the present invention. In the figure, the "refractive projection device i" of the present invention is located in front of a driver's seat of a car, and includes a display unit U, a convex lens 2 (that is, the refractive lens group of this embodiment), an extinction sheet 3 next to the convex lens 2, and a Windshield 4 (the virtual image imaging lens group of this embodiment), wherein the convex lens and the display unit have an included angle Y ′, wherein the angle γ is about thirty degrees. The display unit is a VFD display in this embodiment. In this embodiment, the display unit 丨 丨 projects a letter A that is inverted upside down, and is refracted by the convex lens 2 (that is, the refractive lens group of this embodiment) to form an upright real image, and then passes through the windshield 4 (that is, this embodiment).

Description of the invention (5) The reflection of the imaging mirror is formed in the eyes of the user—enlarge the upright virtual image A. Child display It is not only that μi is arranged between the focal length of the convex lens 2 (that is, the refractive lens group of this embodiment) and twice the focal length to form-enlarge an inverted real image on the convex lens 2 (that is, the refractive lens group of this embodiment). -Side. As the child enlarges the inverted real image because it is located within the focal length of the concave mirror, it transforms to form an enlarged virtual image to the user's eyeball. And the 3 extinction sheet 3 < acts when the incident light 5 i of the external light source is oriented When the convex lens comes, the matting sheet 3 can scatter most of the incident light 51 to prevent it from affecting the display unit. The image projected by u further enhances the sharpness of the image. In particular-general sunlight is incident on the windshield 4 at an angle higher than the line of sight of the image receiver (such as the driver) (that is, the virtual image imaging mirror of this embodiment) Group), part of the incident light is incident on the convex lens 2 (that is, the refractive lens group of this embodiment), but when daylight is incident on the surface of the convex lens 2, it is largely scattered by the extinction sheet 3. Therefore, most of the The incident daylight is eliminated on the surface of the convex lens 2. Even if a small part of the incident day passes through the convex lens 2 (that is, the refractive lens group of this embodiment), it is also because of the convex lens 2 (that is, the refractive lens group of this embodiment). The refraction effect makes the entrance angle not equal to the exit angle, so most of the incident and penetrating daylight will be deflected outside the display unit and not directly into the display unit. Therefore, the display unit 11 shows The image can avoid the influence of ambient light, and the contrast and sharpness of the image. Next, please refer to FIG. 2, which is a part / section view of the second embodiment of the present invention. In this embodiment, most of the images are the same as the first. Implement The example is the same, only a filter film 3 i is provided on the matting sheet 3. As is well known, the light is to expose the points (please read the precautions on the back before filling in the blocks on this page) t ----- -. Silk · This paper size is in accordance with Chinese National Standard (CNS) A4 (210x297 mm) 580585 A7 B7 V. Description of the invention (6) Sunlight contains various wavelengths of light, so the scattering caused by sunlight will follow Light with different wavelengths causes scattering at many angles; and the function of the filter film 31 is to filter out light outside a specific wavelength, so it can greatly reduce the scattering phenomenon caused by incident light and further increase the image projected by the present invention. The clarity. The refraction projection device of the present invention uses a matting sheet to increase the brightness contrast of the formed image, improve the definition, and reduce or eliminate the interference of external ambient light. The imaging principle of the present invention is that the virtual image imaging mainly uses a refraction lens group (convex lens) to form an inverted inverted real image that is upside down from the original image and left and right; and then uses a virtual image imaging unit (concave mirror, concave lens or flat mirror) One is inverted upside down with the original image, and the inverted virtual image is enlarged without changing left and right. The present invention utilizes the formation of a virtual image in the eyeball, so when the user moves 4 images, the image mode caused by the Doppler effect and the ghost effect "reduces g", and the present invention uses refracted light to form a virtual image in the mouth. For the eyeball, only the distance of the entire virtual image imaging lens group or the second refractive lens group (such as a convex lens) is needed to enlarge the image: Cheng Ke; ::: The adjustment method is simple and the space is small. Relatively two sets Projection display devices that are consistent with the user ’s eyeball and require a large space have the relative advantages of simplified operation and flexible use of space. The invention uses refracted light to form a virtual image on the user ’s eyeball. When the dry image transmitted by the ambient light is less than 11, when the surrounding non-users, because of the "refraction imaging", the specifications of the light refraction angle of the virtual image imaging environment group of the agency are not acceptable. 丨 | _Binding ----- ---_ line!
