Abstract
In AMLCDs with two-terminal devices (NLRs), capacitive feedthrough of the trailing edge of the row-select signal («kickback») influences the just-written pixel voltage. This kickback changes with the pixel capacitance, resulting in parametric amplification when using the normal four-level row drive. Instability may occur if the ratio of the pixel capacitance to the NLR capacitance is lower than a certain minimum value. This theory is proven with measurements on a 1-cm 2 pixel, using two lumped diodes with parallel capacitors as an artificial NLR. In D 2 R displays, the sign of the kickback contribution is independent of the pixel voltage. This results alternately in positive and negative feedback in the two fields, and in two different transmission-voltage curves. In practice, this may lead to 25-Hz flicker and a data-dependent dc voltage across the pixel
