A display member according to this invention includes a plurality of pixels. At least one of the plurality of pixels includes a relief structure formation layer including a first region configured to display a predetermined color on a condition, and a second region different from the first region, a first layer made of a first material, and covering at least the first region, and a second layer made of a second material different from the first material, and covering the first layer. The display member displays an image based on a distribution of the first region on the condition that the display member is observed in the oblique direction, and displays an image based on a distribution of the second region on a condition that the display member is observed with transmitted light.

Methods, computer program products, and systems are presented. The methods include, for instance: providing social media feed cognizant lighthouse display service for communicating to spectators, information in regard to social response to an event, the lighthouse display service further including a private display for subscribed event details as encoded with a key to make inaccessible to the spectators but to be decoded on a user device with the key.

Structures for representing images comprise a plurality of tile elements which, when illuminated by a light source, each direct an amount of light toward an observer at a viewing location dependent on their orientation angles. The orientation angles of each tile element may be selected based on a characteristic of a corresponding pixel of an image, such that the observer sees a representation of that image created by the varying amount of light directed to the viewing location by the tile elements.

A display medium comprises a flat member that reflects light, in which the flat member is divided into a plurality of unit cells, and each of the plurality of unit cells is divided into a predetermined number of subcells corresponding to a predetermined number of azimuth angles. Projecting members having a light-blocking surface are formed perpendicular to the flat member on top of the flat member and parallel to a predetermined azimuth angle in each subcell corresponding to the predetermined azimuth angle. The subcells include a plurality of microcells for expressing a color of the content

A method and system of making a secure financial card with dynamic viewing angles is provided. The secure financial card includes a first surface and a second surface opposite the first surface. The financial card includes at least a first portion of indicia and a second portion of the indicia indicative of the card information. The first portion of the indicia and the second portion of the indicia are configured with respective viewing angles and printed on one of the first surface and the second surface. The financial card includes a slide device moveable to different positions associated with different portions of indicia. The slide device allows the respective portion of the indicia to be viewable from different viewing angles. An account number of the financial card is read by rotating the financial card and full card information is unable to be captured by an image of the financial card.

A display body includes a display surface including a plurality of display region groups. Each display region includes at least one reflection surface that is configured to reflect light incident on the display surface toward an area including a corresponding one of reflection directions that are associated with the respective display region groups. Each display region group is configured to form an image unique to the display region group in a corresponding one of the reflection directions through reflection of light on the reflection surfaces in the display region group. The display region groups are configured to form, in two adjacent ones of the reflection directions, different images that have a interrelation between each other.
