Problems solved by technology

Moreover, in the process of quickly adjusting the focus, a large amount of blood flowing through the microvessels around the eyeball will cause pressure on the eyeball. The high intraocular pressure caused by long-term and frequent adjustment of the focus will not only cause discomfort to the human eye, In severe cases, there may be a risk of retinal detachment!

Embodiment Construction

[0021] Please see first figure 2 and Figure 3a , 3b, 3c, this figure 4 is a schematic diagram of the difference between the real image and the virtual image of the eye imaging. figure 2 In the case of the real image 4 projected by the existing projection system, when the eyes regard it as a real image, the eyes must adjust the focus correctly so that the image is imaged on the retina in order to "see" the image 41, and as mentioned in the previous paragraph, The process of focusing puts strain on the eyes. Figures 3a to 3c It is the situation that the eyes of the present invention regard it as a virtual image. In this case, when the imaging mirror group (concave mirror) 260 is transparent, the real image 42 projected by the display unit (not shown) will form a virtual image 43 behind the imaging mirror group 260, and because the human eye When observing the virtual image on the reflective surface, the eyeball adjusts its focus on the reflective surface. Therefore, when ...

Abstract

This invention relates to a display apparatus of dioptric image, which is to locate a projection display device in within cap group. When it projects image information, it can focus light source through diffraction mirror set located in the projection system and then mainly to display on display unit on cap, that is to reduce the light source dissipation by image information of the system through the focal characteristics of diffraction mirror set to improve the image resolution.

Description

technical field [0001] The invention relates to a refraction image display device, in particular to a refraction image display device suitable for making information display clearer. Background technique [0002] The driving safety of motor vehicles is the first priority. However, no matter whether the driving information of a car or a locomotive is often set on a dashboard, when the driver wants to retrieve the above information, he must not pay attention to the driving situation at the same time, so it is easy to create danger. [0003] At present, there is a data projection system designed for car drivers. If it is applied to a locomotive, it is assembled at an appropriate position on the locomotive cap. However, because the locomotive driver is in an open space, except for driving In addition to the relatively high shaking caused by the time, if the external light is strong, such as sunlight, the driving information displayed by the projection system will easily become ...
