Apparatus for addressing an rms-responding, high information content liquid crystal display in which a plurality of first electrodes arranged in a first electrode pattern and a plurality of second electrodes arranged in a second, overlapping electrode pattern provide a plurality of pixels, said apparatus comprising: Means for driving said first electrodes with periodic first signals which are independent of the information to be displayed by said pixels on said liquid crystal display; Means for driving each said second electrodes with a second signal that is indicative of the data to be displayed and proportional at any time to the sum of the products of the amplitude of each first signal at that time multiplied by the state of the corresponding pixel at that first electrode, said state being determined by the information to be displayed by said pixel.
Claim 2
Dependent Claim
62 words
The apparatus of claim 1 wherein said means for driving said second electrodes further comprises means for causing said pixels to display an intermediate optical state between the "on" state and "off" state by selectively controlling the duration of time that a pixel is "on" compared with the time a pixel is "off" over the duration of a plurality successive frame periods.
Claim 3
Dependent Claim
63 words
The apparatus of claim 1 wherein said means for driving said second electrodes further comprises means for causing said pixels to display an intermediate optical state between the "on" state and the "off" state by selectively controlling the duration of time that a pixel is "on" compared with the time a pixel is "off" over the duration of a plurality of time subintervals.
Claim 4
Independent Claim
118 words

Claim 5
Dependent Claim
56 words
The method of claim 4 wherein said column signals cause said pixels to display an intermediate optical state between the "on" state and the "off" state by selectively controlling the duration of time that a pixel is "on" compared with the time a pixel is "off" over the duration of a plurality of successive frame periods.
Claim 6
Dependent Claim
38 words
The method of claim 4 wherein said period is divided into a plurality of equal time intervals and each of said row signals is bilevel and has a substantially constant amplitude for the duration of said time interval.
