The disclosure provides in one aspect a head-up display for a vehicle. The head-up display comprises a picture generating unit, an optical system and a light-selective filter. The picture generating unit is arranged to display a picture on a screen. The optical system is arranged to receive light of the picture. The optical system comprises at least one optical element having optical power arranged to form a magnified image of the picture. The light-selective filter is transmissive to light of the picture and reflective to other light. The light-selective filter is disposed between the optical system and the screen. The light-selective filter has a first surface arranged to receive light from the optical system and a second surface arranged to receive light of the picture from the screen.

Exemplary embodiments of the present disclosure can provide for a transparent panel that can have a featured image which can be surrounded by a pattern of repeating designs on a first side of the panel. A vinyl layer can be provided on the entire first side of the panel to assist in the featured image and repeating designs to be viewable on the second side of the panel (opposite of the first side). On the second opposite side of the panel, an area of the panel where the pattern of designs is visible is provided with a series of lens that can overly the repeating designs. In some exemplary embodiments, the lenses can project enlarged representations of the underlying repeating designs that appear to the eye as occupying a different plane than the featured image, creating a sense of depth within the image.

An image for communication with outside pedestrians is implemented by an afterimage effect by means of a cylindrical display installed at an upper end of a mobility vehicle, and visibility is ensured. In addition, the number of light sources for implementing the image is reduced, an overall size of a lighting device is reduced, and durability and reliability are improved because there is no direct mechanical contact.

Embodiments of the present disclosure describe a light-field display system including a rotatable display screen subsystem, a display screen positioning apparatus, an eye tracking subsystem, and a computer. The rotatable display screen subsystem includes a lamp pole. The lamp pole includes a lamp panel. The lamp panel includes a vector pixel array. The display screen positioning apparatus includes a plurality of lasers and a photosensor. The computer device is connected to the rotatable display screen subsystem and the eye tracking subsystem. The lamp panel controller is configured to determine a position of the lamp panel according to sensed data of the display screen positioning apparatus. Each vector pixel on the lamp panel displays display content in a display direction to achieve 3D image display.

A manually-operated coded image animation device a coded image viewer with a front panel, a reception area, such as a slot open on three sides or a channel, behind the front panel, and coded image decoding elements disposed on the front panel. A coded image card with a plurality of coded images can be manually inserted into the reception area in the coded image viewer. Animation of the coded images can be realized by a sliding movement of the coded image card in relation to the coded image viewer or by a rearward and forward rocking of the coded image viewer in relation to a podium by manual activation. A pivoting structure can be formed by a lever arm, a counterweight, and the coded image viewer with the lever arm received through a slot in the podium. A biasing system biases the coded image card into face-to-face contact with the front panel.

Provided in an illumination device including a display panel including a first surface configured to display an image, a second surface opposite to the first surface, a plurality of display pixels disposed between the first surface and the second surface, and a transmission window configured to transmit light incident on the second surface through the first surface, a light source disposed at the second surface of the display panel and configured to emit light to an object toward the display panel, and a light deliverer disposed between the light source and the display panel, the light deliverer configured to deliver the light emitted from the light source to the object as flood illumination through the transmission window.

Parallel light traveling in a direction perpendicular to an outgoing surface having a curved surface is emitted. A light guide member according to one or more embodiments may include: an incident surface where light from a light source enters; at least one reflective surface that reflects the light having entered from the incident surface; and an outgoing surface that is formed of a curved surface and emits the light reflected by the reflective surface. The reflective surface reflects the light having entered from the light source in a direction in which the incident angle of the light incident on the outgoing surface is constant.

One container system includes a transparent display, a projector for providing image data on the display, and a floor defining part of a watertight cavity. The display is non-perpendicularly angled from horizontal and has proximal and distal ends. And a closure device is provided for use with a watertight container. The closure device is configured to selectively seal an opening in the watertight container and includes coupling structure (a plug, a flange, and/or threading) for selectively coupling the closure device to the watertight container to seal the opening. The closure device further includes non-transitory computer memory, at least one sensor, and a processor in data communication with the memory and the at least one sensor.
