Provided is a display device with three-dimensional sign that can achieve both sign visibility and a variety of presentation effects. The display device with three-dimensional sign 1 includes: a display panel 11 that has a transparent panel 11a on a front surface and that displays an image including a still image and/or a moving image; and a control unit 3 that controls display of the image in the display panel 11, the display device further including a thick, translucent three-dimensional sign part 10 that is provided in a part of the front surface of the transparent panel 11 and formed into a shape representing a character, a graphic, or a pattern.

A virtual image display device according to an embodiment is a virtual image display device that displays information to a passenger on a vehicle. The virtual image display device includes a first virtual image display unit that displays a virtual image as information. The first virtual image display unit has a virtual image display portion that displays a virtual image and a rotating unit that rotates the virtual image display portion in a range in which the virtual image is visually recognizable by the passenger.

An apparatus for displaying a three-dimensional image includes a base; a driving mechanism disposed on the base; a support element movably mounted to the base and controllably driven by the driving mechanism; and a light source set disposed on the support element and configured to controllably form a predetermined pattern of light emission; wherein the driving mechanism is configured to move the support element in a predetermined pattern of movement, a plural-ity of light emission patterns formed by the light source set during the movement of the support element collectively constituting a three-di-mensional image perceptible by a human eye. A method for displaying a three-dimensional image is also disclosed.

An improved advertising system can include a location having a substantially large expanse of living greenery, a predetermined design for an advertisement, and a chlorophyll-based agent. The location can be observable by viewers at a predefined minimum viewing distance. The chlorophyll-based agent can be used to paint the predetermined design on the living greenery. The chlorophyll-based agent can be non-detrimental to the health of the living greenery. The predetermined design painted on the living greenery with the chlorophyll-based agent can be only viewable by viewers at the predefined minimum viewing distance. Living greenery treated with the chlorophyll-based agent can be visibly distinguishable from and shinier than neighboring untreated living greenery. When a viewer is nearer than the minimum predefined viewing distance, a difference in shine and color between the treated living greenery and the untreated living greenery can be substantially unnoticeable.

A vehicle display system is able to integrate with a license plate holder and replace a license plate to digitally display a name, phrase, logo, or other image. A series of light-emitting diodes may be arrayed across a plate and may be in communication with a digital controller. The controller and the diodes may be powered by the vehicle's electrical systems and may communicate wireless with an external device. In this way, the controller may cause the diodes to display an image which may be energized, deenergized, and customized by the user utilizing the external device. The diodes are encased by a thick lens which draws out the image of the lighted diodes into a three-dimensional hologram, providing depth and visibility to the image.

Disclosed is a three-dimensional advertisement device. The present invention includes: a frame having a predetermined shape; a plurality of unit cells supported by the frame and arrayed in an X-Y matrix; and a controller for selectively driving the unit cells according to an external input signal, wherein the unit cell includes: a cell plate having a magnet on a rear surface thereof and having an upper end hinge-coupled to the frame, the cell plate being vertically disposed; and an electromagnet arranged to face the magnet of the cell plate to enable the cell plate to rotate forward when power is applied thereto according to a signal of a controller. The cell plate of the unit cells includes a reflection plate such that advertisement text is three-dimensionally expressed through a combination of the cell plates which rotate to be opened.

There is disclosed a three-dimensional display device including: a micro LED display panel, a light control component arranged at a light-emitting side of the micro LED display panel, and a control component electrically connected with the micro LED display panel and the light control component respectively; where the control component is configured to control the micro LED display panel to display, and to control the light control component to generate a parallax barrier matching with the micro LED display panel, in a three-dimensional display mode. The control component controls the light control component to generate the parallax barrier matching with the micro LED display panel, while controlling the micro LED display panel to display, and when light rays emitted by the micro LED display panel pass through the parallax barrier, a three-dimensional image can be displayed, so that a three-dimensional display can be achieved on the micro LED display panel.

A system for creating three-dimensional grass graphics can include a means for cutting grass with an adjustable cutting height, a chlorophyll-based agent for coloring grass, and at least one stencil. The chlorophyll-based agent can be non-detrimental to a health of the grass and can be available in multiple shades. The stencil can be securable to the grass and can define a graphic to be painted on the grass using the chlorophyll-based agent. The means for cutting the grass can be able to pass over and around the stencil without damaging the stencil. Application of different shades of the chlorophyll-based agent to varying heights of grass can produce a three-dimensional effect for the graphic when viewed.
