Problems solved by technology

[0004] However, in some cases the above solution can also cause trouble
For example, in a cabin or a vehicle, if multiple people use the above-mentioned projection game devices at the same time, the images projected by multiple devices may overlap and interfere with each other
In addition, since the projected content can be seen by many people at the same time, it is not suitable for use when the displayed content involves personal privacy
[0005] In addition, two-dimensional plane image display has become increasingly difficult to meet people's requirements, and people have begun to pursue three-dimensional display effects
In this regard, the display device of existing portable electronic equipment is just more and more insufficient.

Embodiment Construction

[0018] Some exemplary embodiments of the present invention will be described below in conjunction with the accompanying drawings, so as to better understand the present invention. In the description of the present application, the same reference numerals denote the same elements.

[0019] figure 1 shows a schematic structural diagram according to the first embodiment of the present invention, Figure 1a It is a plan view of the structure viewed along the direction of entering the paper (along the -Z axis in the figure, that is, along the opposite direction of the Z axis). The display device 100 of the first embodiment can be used in head-mounted structures such as helmets or glasses connected to various portable electronic devices. Although a portable game device is used as an example of an electronic device in this application, it should be understood that the present invention is not only applicable to a portable game device, but also to almost all kinds of electronic devi...

Abstract

The invention discloses a head type display device, which includes light source, the first light modulation device and the second light modulation device, wherein, the first light modulation device modulates one part of light emitted from light source by the first light modulation information, the second light modulation modulates the other part of light emitted from light source by the second modulation information different from the first modulation information, after modulations the two parts of light communicate along uncoincidence paths, which makes the head type display device provide three dimensional display for users. The head type display device provided by the invention has simple structure, while keeping highly portable, and can privately maintain display information to a certain extent, and display stereoscopic view, in order to improve the display performance of portable type game device.

Description

technical field [0001] The invention relates to a head-mounted display device, in particular to an optical path structure of the head-mounted display device capable of displaying stereoscopic images. Background technique [0002] With the development of electronic technology, portable game devices have been greatly developed in recent years. Series game consoles such as Xbox and Play Station have been able to meet the needs of complex and large-scale games in terms of storage and computing processing capabilities. However, for reasons of portability, these gaming devices are a bit underwhelming in terms of display. Although their resolution is already comparable to that of ordinary desktop computer monitors, due to the limitation of the overall size of the device, its screen (usually an LCD screen) cannot have a large physical size, so the display effect is still limited. [0003] In order to overcome the above disadvantages, a solution is not to use (or selectively not to ...
