Double block refraction imaging display machine

Abstract

A dimmer dioptric imaging display machine mainly comprises two display units; two reflection units located by one side of said display unit to polarizedly refract the sending light from display unit and with two display units between the two reflection units; two refractor mirror sets located by one side of said reflection unit but the second refractor set isn't located in the line formed by the reflection unit and first refractor set; and two virtual image forming sets separately located by two other sides of the two refractor sets to polarizedly refract the light sent from refractor and its image is converted into virtual image through virtual image forming set; the refractor set located between reflection unit and the virtual image forming set. And the image displayed in the display unit is polarizedly refracted into a handstand real image by the refractor set through reflection unit and again is converted into a virtual image with handstand direction with original image through virtual image forming set.

Description

technical field [0001] The invention relates to an image display device, especially an image display device suitable for glasses or helmets. Background technique [0002] In recent years, various audio-visual equipment and display devices have been improved with each passing day. In addition to enhanced functions, thin, light, small, and portable displays have also become the mainstream of display development. One of the emerging display devices is virtual reality (virtual reality) technology. The integration of various technologies, such as display technology, computer technology, sensory technology, and sound effect technology, has reduced the original large-sized audio-visual equipment into a portable glasses-type projection display device. Although the general flat panel display is light in weight, its size is limited by material weight and cost, and it cannot achieve the effect of enlarging the image size and being easy to carry at the same time. Therefore, the current...

Moreover, in the process of rapid focus adjustment, a large amount of blood in the microvessels around the eyeball will cause pressure on the eyeball. The high intraocular pressure caused by long-term and frequent focus adjustment will not only cause discomfort to the human eye, but also seriously Those who are more afraid of the risk of retinal detachment! Therefore, if this kind of real image projection device is applied to a glasses-type display device, when the observation time (within a few hours) is prolonged, the intraocular pressure of the observer will increase, resulting in symptoms of dizziness and discomfort, and even severe retinal detachment. Therefore, it is not suitable for young children or those with heart disease or high blood pressure

However, if the real image is projected on the eyeball, if the magnification is to be increased, the distance between the projection lens group and the eyeball needs to be lengthened. In this way, if the image magnification is to be increased, the space occupied by the projection system needs to be increased, which is not practical. Not practical

[0004] In addition, when the user's head moves, the display device that forms a projected real image in the eyes will produce image blur or severe shaking due to ghosting and Doppler effect, so the display quality is not good, and the application field is not wide.
