Multicolored liquid crystal display
First Claim
1. A display for an intensity level measuring device of the general type in which the intensity level is converted by an electronic circuit into a corresponding voltage level, the display comprising a multicolored liquid crystal display, the liquid crystal display comprising a plurality of shutters, each shutter defining a display window, at least some of the display windows when activated being of a different preselected color or colors from some other activated windows, each shutter being activatable by electronic circuitry responsive to a unique minimum voltage level generated by the electronic circuit, the preselected color or colors of each window remaining unchanged at a voltage level above its minimum unique voltage level whereby the display indicates an intensity level according to the colored display window corresponding to the activated shutter.

Abstract
There is disclosed a multicolored liquid crystal display for use in intensity level measuring devices of the general type in which the intensity level is converted into a corresponding voltage such as vibration meters. The liquid crystal display has a plurality of shutters. Each shutter defines a display window that is a selected color, and each shutter is activatable by a unique voltage input level. Colors for the display windows are selected which have a universal meaning so that the readout may be easily understood.
