  • View finder device having liquid crystal cell
    Patent number: 4140378
    Abstract: A liquid crystal cell is provided within a camera viewfinder. In the cell, a liquid crystal is sandwiched between a resistance layer mounted on a substrate and another substrate-mounted layer which may be either resistive or conductive. Suitable means mask at least the end portions of the display of the liquid crystal cell. In operation, voltages corresponding to photographic conditions are applied to the layers to produce analog data indicative of photographic conditions.
