ABSTRACT:
The apparatus includes a liquid crystal cell having transparent front and back walls with transparent electrodes on their facing sides and a liquid crystal material between the walls. The electrodes are segmented into matrix elements according to the cumulative pattern of all characters desired to be displayed or recorded, and are electrically addressable in response to selection circuitry. The front wall is in the form of a fiber-optic plate comprising a plurality of parallel arranged optical fibers. The apparatus is particularly useful to display or record measurement data, such as from a weighing device.
