The lenticular lens panel includes a first substrate disposed on the display panel, a second substrate disposed opposite to the first substrate, an insulating layer disposed between the first substrate and the second substrate, where a plurality of lenticular lens surfaces overlapping the lenticular lens area and a groove overlapping the sealing area are defined on the insulating layer, a sealing member disposed in the groove, where the sealing member combines the first substrate with the insulating layer, and a plurality of liquid crystal molecules disposed between the lenticular lens surfaces and the first substrate.

According to an embodiment of the disclosure, an electronic device may include a housing including a rear plate including a first region having a first concavo-convex pattern formed therein, and a second region having a second concavo-convex pattern formed therein, and a processor disposed inside the housing. The first concavo-convex pattern and the second concavo-convex pattern may be integrally formed with the rear plate, and a first depth of the first concavo-convex pattern may be different from a second depth of the second concavo-convex pattern.

Provided is a display apparatus for a three-dimensional (3D) head-up display (HUD), the display apparatus including a transparent substrate, a polarizing film layer provided on the transparent substrate, and a lenticular lens provided on the polarizing film layer opposite to the transparent substrate, wherein the lenticular lens includes an adhesive layer, a base substrate provided on the adhesive layer, and a pattern layer provided on the base substrate opposite to the adhesive layer.

A fixed-focus lens includes an anti-radiation first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens arranged in order in a direction. An aperture stop is disposed between the first lens and the fourth lens. A ratio of a lens diameter of the first lens to an overall length is within a range of 0.4 to 0.5, where the overall length is an axial distance between an outer surface of the first lens and an outer surface of the seventh lens. Each of the first lens to the seventh lens is a spherical glass lens.

A compact folded projection system is described that includes a laser light source, a folded lens system comprising a lens stack including two or more refractive lenses and a light folding element (e.g., a prism), and a diffractive beam splitter that includes at least one diffractive surface. The light folding element provides a “folded” optical axis for the lens system to reduce the Z-height of the projection system, for example to within a range of 1.7 to 4 millimeters (e.g., 2 millimeters in some implementations). The laser light source emits light that is refracted by the lens stack to the folding element. The folding element redirects the light to the beam splitter which replicates the light into N×M duplications or tiles to thus generate a larger field of view (FOV) than the internal FOV of the lens system.

The invention provides an automotive lighting device with a circuit support, an optics support, a holder support and a microlenses support. The optics support includes optical elements, each one being arranged in front of one of the solid-state light sources of the printed circuit board. The optics support further includes positioning protrusions configured to fit the positioning housings of the circuit support. The holder support includes a plurality of opaque walls, a first coupler and a second coupler. Each opaque wall is located between two optical elements. The microlenses support includes a plurality of groups of microlenses, each group having a plurality of microlenses arranged to receive the light projected by one optical elements. The first coupler is configured to couple the holder support to the circuit support. The second coupler is intended to retain the microlenses support.

A method for manufacturing a visual display assembly, comprising: providing a film of transparent material comprising a first surface and a second surface opposite the first surface, the first surface comprising an array of lenses comprising information that is arranged so as to be capable of providing multiple images when the images are viewed from different predetermined angles through the lenses; placing a screen-printing fabric in proximity to the first surface in order to form a pattern or printed image; applying a layer of ink or varnish to the screen-printing fabric allowing the ink or varnish to pass through for placement on a portion of the first surface; wiping the ink or varnish by means of a squeegee over the screen-printing fabric.
