Embodiment Construction

[0036] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0037] figure 1 is a schematic structural diagram of an existing near-eye display device, figure 2 Schematic for near-eye display. The principle of spliced ​​imaging near-eye display is to use field of view splicing, and use the combination of microlens array and pixel island array to realize near-eye splicing imaging. like figure 1 As shown, the main structure of the spliced ​​imaging near-eye display device includes a substrate 10, a microlens array 20, and a pixel island array 30. The microlens...

Abstract

The embodiment of the invention provides a near-eye display device and virtual / augmented reality equipment. The near-to-eye display device comprises a substrate, a combined microlens array arranged on the substrate and a pixel island array located on the side, away from eyes, of the substrate, the combined microlens array comprises a plurality of combined microlenses arranged at intervals, and the pixel island array comprises a plurality of pixel islands arranged at intervals. Each pixel island corresponds to one combined micro lens, and each pixel island is arranged at the focal point of the corresponding combined micro lens; and each combined microlens comprises a first microlens arranged on the surface of the side, facing the eye, of the substrate and an additional microlens arranged between the first microlens and the pixel island. Through the arrangement of the combined microlens array, the pixel points at the edge parts of the pixel islands can form an effective view field, the number of the pixel points under each lens view field angle is increased, and the display resolution is improved on the premise of meeting the requirements of light and thin near-to-eye display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a near-eye display device and virtual / augmented reality equipment. Background technique [0002] Virtual reality (Virtual Reality, VR) and augmented reality (Augmented Reality, AR) devices have been gradually applied to display, games, medical and other fields, and the near-eye display technology used to realize VR / AR has received more and more attention and research. Near-eye display is a display technology that enables viewers to see clearly the content that is very close to the eyes. The optical system is used to image the displayed content within the focus range of the eyes, so that the eyes can see the displayed content clearly. [0003] Traditional near-eye display devices usually use a microdisplay and a single-lens structure. Due to the current technological level, it is difficult to improve the resolution of the microdisplay, and due to the limitation of the relative ap...
