Description

Direct-view near-eye display device

The present invention relates to a display device, especially a wearable near-eye display device.

With the rapid development of technology, near-eye display devices that can be combined with glasses have also begun to be applied in various fields. Near-eye display devices can build a display directly in front of the user's field of vision, and display various digital content on the display.

Most of the existing near-eye display devices are transparent near-eye display devices, which use a see-through display as a display, so that the transparent screen can display digital content while allowing users to see the surrounding environment. Image, the visual image of the surrounding environment will appear behind the screen as a background. This characteristic also enables the transparent near-eye display device to be applied as a tool for implementing augmented reality technology.

In the current technology, most of the transparent near-eye display devices use light beam projection to form an enlarged virtual image at an appropriate position in front of the user's eyes, so that the user can see the relevant digital information. However, if the ambient light is too strong or the color tone is too similar, it will easily affect the clarity of the displayed image. On the other hand, the image displayed by the transparent near-eye display device will still block or block the user's field of vision more or less, or it is necessary to turn the eyeball to view the displayed image information, such as the user is in a moving state , part of the field of vision obscures or changes the viewing direction of the eyes, which is likely to cause safety concerns.
