A scan display system includes a picture receiving unit, a scan needle, a picture display screen having first and second opposing surfaces, and a driving unit. The picture receiving unit is configured to receive picture data and transmit the picture data to the scan needle. The driving unit is configured to perform a picture scanning process by moving the scan needle to scan in a vertical direction relative to the first surface of the picture display screen at a predetermined frequency. The scan needle is configured to emit light, representative of the picture data, to the first surface of the picture display screen to project image lines, each image line being projected by the scan needle during the scan. The picture display screen is configured to receive the emitted light on the first surface and display an image comprising the image lines on the second surface.

A messaging apparatus for wearable items. The messaging apparatus may comprise a light source, at least one sensor to detect an event, and a controller to control the flashing of the light source in response to the detection of the event. The controlling of the flashing of the light source may generate at least one visible element that is visible to a viewer. Further, the light source may not be adapted in the form of the at least one visible element, but rather, the controlled flashing of the light source may be in the form of the at least one visible element.

Disclosed is a device that attaches to a smart phone to provide a portable fan and text display. Using either an iOS or OTG (Android) connection, fan blades are powered by the smart phone connection, providing a cooling breeze that can directed toward an individual. In addition, LEDs are mounted on one of the fan blades and are synchronized to illuminate during fan blade rotation to provide persistence of vision, wherein text images are readable by the human eye. Text messages can be preprogrammed or, in an alternative embodiment, entered directly from the smart phone.

Apparatuses and methods for displaying a 3-D representation of an object are described. Apparatuses can include a rotatable structure, motor, and multiple light field sub-displays disposed on the rotatable structure. The apparatuses can store a light field image to be displayed, the light field image providing multiple different views of the object at different viewing directions. A processor can drive the motor to rotate the rotatable structure and map the light field image to each of the light field sub-displays based in part on the rotation angle, and illuminate the light field sub-displays based in part on the mapped light field image. The apparatuses can include a display panel configured to be viewed from a fiducial viewing direction, where the display panel is curved out of a plane that is perpendicular to the fiducial viewing direction, and a plurality of light field sub-displays disposed on the display panel.
