An invisible, light-transmissive display system with a light resistant material is provided. Substantially invisible, tapered, light-transmissive holes are penetrated in a light transmissive pattern through at least a portion of the light resistant material using a laser beam having a focal width less than the smallest diameter of the tapered holes.

Embodiments are directed to an electronic device having a hidden or concealable input region. In one aspect, an embodiment includes an enclosure having a wall that defines an input region having an array of microperforations. A light source may be positioned within a volume defined by the enclosure and configured to propagate light through the array of microperforations. A sensing element may be coupled with the wall and configured to detect input received within the input region. The array of microperforations are configured to be visually imperceptible when not illuminated by the light source. When illuminated by the light source, the array of microperforations may display a symbol.

A simulating neon lamp is disclosed, which comprises a bottom base (10), a back, light source (20), a display assembly (30) and a cover plate (40); wherein the bottom case (10) is opaque and hollow and has an opening facing upward; the back light source (20) is mounted in the bottom case (10); the display assembly (30) is translucent and fixed onto the bottom case (10) to close the opening; the display assembly (30) comprises a first display panel (31); the sectional width of the first display panel (31) is less than that of the bottom case (10), and an upper surface of a connection where the first display panel (31) is connected with the bottom case (10) is not higher than a top end of the bottom case (10): the cover plate (40) is opaque and covers the connection where the first display panel (31) is connected with the bottom case (10) so as to shield the light penetrating from a gap of the connection where the first display panel (31) is connected with the bottom case (10). The present invention has such advantages as safety, energy-conservation and low cost, excellent effect simulating a neon lamp and so on.

An illuminated sign for providing a warning that an area adjacent the illuminated sign is within a field of view of an audio/video (A/V) recording and communication device. The illuminated sign may include a front panel having translucent portions and opaque portions, and an illumination source located behind the front panel. The illumination source illuminates the front panel such that the opaque portions block transmission through the front panel of at least a portion of the light from the illumination source to provide the warning that the area adjacent the illuminated sign is within the field of view of the A/V recording and communication device.

An image sheet capable of maintaining good image quality without a change in density or color in a low-density part of an image is provide. The image sheet for both transmitted light and reflected light includes: a base layer formed of a light-transmitting white resin film; a first image layer formed of a first color image formed on one surface of the base layer; a second image layer formed of a second white image formed on the first image layer so that a position of the same image as the first image is superimposed on the position of the first image; and a third image layer formed of a third color image formed on the second image layer so that a position of the same image as the first image is superimposed on the position of the first image.

A light guide plate guides light from a light source to form an image in a space, and includes a light introduction portion and a light emitting portion. Light from the light source is incident on the light introduction portion. The light emitting portion includes a curved emission surface that emits light from the light source incident from the light introduction portion, and is bent and connected to the light introduction portion.

A lighting system for a hat includes a front housing containing lighting elements that mates with a back plate positioned on the inside of the hat. Driver circuitry controls operation of the LEDs for various lighting modes, and a cover for the front housing is translucent and designed in the shape of a recognizable logo or other design. Electric power comes from a battery located on the back plate, and is provided through the hate using prongs or projections that pass through the hat, from the back plate to a circuit connector in the front housing. The circuit connector is electrically coupled to circuitry on a circuit board in the front housing.
