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.

An edge plated printed circuit board (PCB) improves radiated emission performance by enhancing ground shielding on the PCB and improving the physical and electrical connection between the PCB and external EMI suppression components including an EMI chassis and gaskets. Inner ground layers within a multi-layer PCB are configured to physically extend to an edge of the PCB, which is plated using copper electroplating, so that copper ground strips disposed at the top and bottom surfaces of the PCB and the inner ground layers are all electrically coupled to the plated edge. In some embodiments, the ground strips can be made thinner compared to conventional arrangements, or be eliminated altogether as a result of the direct connection between the edge plated PCB and external EMI shields.
