    Abstract: A near-eye display device, comprising: a pixel island assembly, comprising a plurality of light-emitting elements; and a microlens array assembly, comprising a microlens array and an optical surface member, the optical surface member having an optically transmissive free-form surface, a planar total-reflection surface and an optically reflective free-form surface, each surface of which intersects with other two surfaces; wherein light emitted by the pixel island assembly enters the optical surface member through the optically transmissive free-form surface, is reflected by the planar total-reflection surface and by the optically reflective free-form surface in sequence, and then exits the optical surface member through the microlens array.

    Abstract: There is provided a near-to-eye display device, including: a pixel island array, a micro-lens array and a filter layer. The pixel island array and the micro-lens array are fixed with respect to and spaced apart from each other, and the micro-lens array includes plural micro-lenses. The pixel island array includes plural pixel islands in one-to-one correspondence with the plural micro-lenses, and each pixel island emits light to the corresponding micro-lens such that the light reach a predetermined viewing position after passing through the corresponding micro-lens. The plural pixel islands emit light of plural colors, and the filter layer includes plural filter portions in one-to-one correspondence with the plural pixel islands. Each filter portion is located between the corresponding pixel island and the corresponding micro-lens, and is close to the corresponding micro-lens. Each filter portion and light emitted by the corresponding pixel island have a same color.

    Abstract: A transparent display panel has a plurality of sub-pixel regions, which are divided into at least two display unit groups. The transparent display panel includes a first substrate and a second substrate assembled with each other, and a light exit control layer disposed therebetween. The first substrate includes a first base and a dimming component disposed on a side of the first base. The dimming component includes a plurality of dimming lenses. Each dimming lens is configured to transmit exit light of one sub-pixel region to human eyes and focus the exit light on a corresponding focal plane. The plurality of dimming lenses are configured to focus exit light of the at least two display unit groups on different focal planes. The focal planes are located at a side of the transparent display panel away from the human eyes.

    Abstract: A near-to-eye display apparatus includes a plurality of pixel island groups. Each pixel island group includes a plurality of pixel islands. Each pixel island corresponds to a micro lens. By adjusting a position of the micro lens relative to the corresponding pixel island in the pixel island group, on a plane where the micro lenses are located, or a position, of the pixel island in the pixel island group relative to the corresponding micro lens, on a plane where the pixel islands are located, imaging points in the imaging regions formed by at least part of different pixel islands in the pixel island groups do not overlap with each other and are arranged alternately.
