Abstract: The technology of this application relates to a board-level structure that includes an upper-layer substrate, a lower-layer substrate, and a plurality of support members that can be supported between the upper-layer substrate and the lower-layer substrate. In an example embodiment, a gap exists between the upper-layer substrate and the lower-layer substrate, the gap includes at least one first gap region and at least one second gap region, the first gap region and the second gap region are spaced, a spaced region between the first gap region and the second gap region does not include the first gap region or the second gap region, and a maximum vertical distance between the upper-layer substrate and the lower-layer substrate in the first gap region is less than a minimum vertical distance between the upper-layer substrate and the lower-layer substrate in the second gap region.

Abstract: A near-eye display and a near-eye display system are provided. The near-eye display includes a display panel, a collimation lens component, and an optical redirector. The display panel includes a plurality of pixels that are disposed in a tiling manner. The collimation lens component includes a plurality of collimation lenses, and the plurality of collimation lenses are in a one-to-one correspondence with the plurality of pixels. Each of the plurality of collimation lenses is configured to: convert, into collimated light, light emitted by a corresponding pixel, and input the collimated light into the optical redirector. The optical redirector includes a plurality of light convergence structures, and the plurality of light convergence structures are in a one-to-one correspondence with the plurality of collimation lenses. Each of the plurality of light convergence structures is configured to converge, on a focus of the near-eye display, collimated light input by a corresponding collimation lens.
