A marker board system having a dark colored, low hardness, low surface energy solid silicone sheet to wet to a vertically oriented high surface energy substrate on a smooth, flat back-side of the solid silicone sheet. A front-side of the solid silicone sheet is able to be written upon by brightly colored marker ink. The brightly colored marker ink is able to be easily erased from the front-side of the solid silicone sheet after being written upon the front-side of the solid silicone sheet.

Electro-optic, especially electrophoretic, displays are used in variety of architectural and furniture applications, including a tile (100) comprising an electro-optic layer (110) capable of changing the color of the file, front and multiple rear electrodes and a light-transmissive polymeric layer (102), the exposed surface of which is textured to provide a plurality of facets inclined to the plane of the tile (100), the rear electrodes being aligned with the facets. A variable color writable board is also provided.

A drawing device with a rotatable display screen is provided, having a housing having a cavity therein and a display screen sealingly rotatably coupled to the housing. An inner surface of the display screen forms an enclosure with the cavity. A powder is contained within the enclosure, the powder being removably adherent to the inner surface of the display screen. A first stylus controller is supported on an exterior of the housing. At least one positioning structure is supported in the enclosure and coupled to the first stylus controller to move a first stylus in a first set of directions that are parallel to a first axis. The first stylus removes the powder from the inner surface of the display screen through contact with the inner surface of the display screen.

A multifunctional illuminated lighting pad is an apparatus that enables a user to write with one hand, rather than requiring a hand to hold a clipboard or writing surface and another hand to write down information. The apparatus provides a mechanism by which to secure to a user, thus preventing difficulty or danger resulting from a loose clipboard. An illumination source provides ample light, allowing the user to read and write in otherwise poorly-lit areas. A portion of the opaque backing may be secured to a user's pocket and molded to the rough curvature of a leg. An exposed portion of a backing surface holds a writing surface, an LED, and a clip. A thumb-pull cut allows the user to insert or remove a reference sheet from between the plexiglass front plate and the backing, thus allowing the user to refer to information behind the plexiglass front plate while writing.

The present disclosure relates to an electronic blackboard, including a liquid crystal display panel and at least one metal panel, wherein the liquid crystal display panel includes a liquid crystal screen, and a surface of the liquid crystal screen is provided with a glass board; the metal panel comprises a first metal sheet, a supporting board and a second metal sheet, with same being sequentially arranged; and a surface of the first metal sheet is coated with a coating for writing on with a piece of chalk or a stylus pen.

A plurality of modular tiles can be connected to form a writing surface. The modular tiles are shaped to enable multiple tiles to be connected to form a continuous surface (e.g., hexagonal, rectangular, etc.). Each modular tile has a writing element and a friction element opposite the writing surface to prevent the modular tile form slipping when placed on a horizontal surface. The modular tiles may also have a coupling mechanism, such as magnets with appropriate polarization, allowing the modular tiles to be coupled to one another to form a large surface and then be detached for simpler storage of the modular tiles. The modular tiles may further include lights, displays, or additional electronics to allow a connected computing device to display on the writing surface.

A collapsible writing board is provided comprising: a sheet of writing material with a writing surface; a plurality of rigid elongate segments affixed to the sheet; and at least one segment connector affixed to each rigid elongate segment; wherein the at least one segment connector provides planar support to enable the rigid elongate segments to assemble into a first state, such that the rigid elongate segments are substantially aligned on a support plane to support the sheet of writing material, and to assemble into a second state, such that the rigid elongate segments are unaligned from the support plane, to facilitate storage of the collapsible writing board.

A method of updating an electrophoretic display that makes use of an electrophoretic display capable of receiving and displaying a transmitted digital photograph, a marker and a digital camera capable of transmitting digital images to a destination, the display including a transparent cover that can be marked on by the marker. First, an image is displayed on the electrophoretic display, and the marker is used to mark the cover, thereby forming markings. Then a digital photograph of the display is taken with the digital camera. Finally, the photograph is transmitted to the electrophoretic display and displayed on the electrophoretic display, thereby displaying both the image and the markings.
