Display adjustment method for near-eye display

The present invention relates to a display adjustment method for a near-eye display, and more particularly to a display adjustment method capable of adjusting an output image capable of being clearly displayed through a fusion technique, a collimation technique, or/and a lead angle technique. .

In response to the increasing demand for instant information in modern society, the delivery of on-demand information has received much attention. The near-eye display is a good choice for portable personal information devices because of its portability and the ability to update and deliver images, colors or text at any time in conjunction with electronic devices. Early near-eye displays were mostly military or government use. Recently, some manufacturers have seen business opportunities and introduced near-eye displays to homes. In addition, entertainment-related industry also sees the potential of this market, such as home game instruments and game software related manufacturers have invested in research and development.

Currently, the near-eye display (NED) includes a head-mounted display (HMD) that projects images directly into the viewer's eyes. This type of display can overcome other action display form factors by synthesizing a virtual large-format display surface. Available in a limited screen size, or for virtual or augmented reality applications.

The near-eye display can be subdivided into two major categories: immersive displays and see-through displays. An immersive display can be employed in a virtual reality (VR) environment to fully encompass the user's field of view using a composite rendered image. In augmented reality (AR) applications, a see-through display can be used in which text, other synthetic annotations, or images can be overlaid in the field of view of the user in a physical environment. On display In terms of technology, AR applications require a translucent display (eg, by optical or electro-optical methods) so that a near-eye display can be used to simultaneously view the physical world.

However, since the human eye cannot focus (focus) on the fact that the object is placed at a close distance (for example, when the user is wearing glasses, reading the distance between the lens of the magnifying glass and the user's eyes). Difficult to construct. Therefore, the near-eye display must be adjusted to make the viewer comfortable to use, otherwise it will cause the occurrence of defocusing and other effects, but the traditional use of complex and cumbersome optical components to adjust, but because of the near-eye display Most of them must be worn directly on the viewer's head, so the near-cuddly near-eye display is often not acceptable to consumers.

Therefore, in order to overcome the above problems, if the output image can be clearly displayed through a fusion technique, a collimation technique or/and a lead angle technique, the use of bulky optical components is eliminated, and the saving can be achieved. The extra cost of using bulky optics should be an optimal solution.

The present invention provides a display adjustment method for a near-eye display, which can be adjusted by a fusion technique, a collimation technique, or/and a lead angle technique to enable the output image to be clearly displayed, so that no bulky use is required.
