See-through display device capable of ensuring an ambient field-of-view

Abstract

There is provided a see-through display device capable of ensuring an ambient field-of-view. The see-through display device includes a display control board; a display element configured to emit image light according to an image signal generated in the display control board; a first prism that has an incident surface parallel to the display element, a tiled first emission surface and a second emission surface perpendicular to the incident surface; a partial reflection filter configured to reflect some image light emitted from the first prism and penetrate the remaining image light; and a second prism that has an incident surface having the same angle as the emission surface of the first prism, a curved reflection surface in which image light incident on the incident surface is reflected with positive power and guided to pupils of a user and an emission surface emitting image light to the pupils of the user.

Description

technical field [0001] The present invention relates to a see-through image display device, and in particular to a see-through display device capable of ensuring a wide field of view around the periphery without any obstacle in the visible area between two eyes so as to be able to recognize a wide front situation as in a natural state. -throughtypedisplayapparatusbeingabletoensurewidefieldofsurroundview). Background technique [0002] Generally speaking, a display device uses sophisticated optical devices to make the image light generated at a position very close to the eyes form a focus in a way that can form a virtual large screen in the distance, so that the user can see the magnified virtual image. Image display device, the display device is divided into only can see the image light diverged in the display element and the surrounding environment is invisible closed (See-close) and can not only see the surrounding environment through the window, but also can see at the sa...

Problems solved by technology

In this way, the overlapping area of ​​images that can be normally observed by both eyes is limited to area c, so the user will have a very annoying feeling that the center is blocked, and what the two eyes see are images of different states. Therefore, in In the case of using such a device for a long time, there is a problem that the user is prone to eye fatigue and dizziness

[0010] Additionally, if Figure 3b As shown in , in the case of using this kind of see-through display device, there is a problem that the user can only view the external panorama to a limited extent with the feeling of a partition wall with an angle of about a in the center of the two eyes.
