Enrobed core

An enrobed a core, such as a tablet core, that has a coating made of one or more patterned films each having portions that are visually distinct (e.g., differently colored) from one another and having a transition line segment between these visually distinct portions. At least a portion of an outer surface of the core is covered with the film or films, such that the transition line segments form a substantially continuous transition line on the coating and a film seam is formed which is different from the transition line. Where the patterned films are bi-colored, the resulting enrobed core can be bi-colored, or the resulting enrobed core can have a coating with at least four visually distinct portions alternately arranged thereon, thereby forming a “checkerboard” pattern on the coating. In either case, the film seam of the coating is different from the transition line of the coating.

Process for enrobing a core

A process for enrobing a core, such as a tablet core, uses a coating that is made of a patterned film having portions that are visually distinct (e.g, differently colored) from one another and having a transition line segment between these visually distinct portions. At least a portion of an outer surface of the core is covered with the film, such that the transition line segment forms a substantially continuous transition line on the coating and such that a film seam is formed which is different from the transition line. Alternatively, the coating is formed from two such patterned films, in which case the outer surface of the core is covered with the two films such that the two transition line segments cooperate to form a substantially continuous transition line on the coating and a film seam is formed which is different from the transition line. Prior to covering the outer surface of the core, the two films may be oriented such that the resulting enrobed core has a bi-colored coating with two visually distinct portions each lying on opposite sides of the transition line of the coating. The two films may also be oriented such that the resulting enrobed core has four alternately arranged colored portions, two of which are of a first color and the other two of which are of a second color, thereby resulting in a “checkerboard” effect.

Liquid crystal device for generation and fast switching of high contrast images

An electro-optic device including a liquid crystal material is disclosed, comprising antiferroelectric liquid crystals with large molecular tilt θ of about 45° degrees, disposed between two flat glass or polymer substrates. The liquid crystal molecules are preferably oriented parallel to the substrates (so-called HAF texture). The device is e.g. placed between two crossed polarizers so that in field-off conditions the impinging light is not passing through the device due to the isotropic optical properties of the antiferreoelectric liquid crystal aligned in HAF texture. An applied electric field induces a continuous transition of the optically isotropic antiferreoelectric (AF) state to ferroelectric (F) one which is birefringent enabling the transmission of light. The field-induced continuous switching between the optically isotropic antiferreoelectric state and the birefringent ferroelectric state enables the generation and fast switching of high contrast as well as generation of grey scale levels.
