Abstract
Light influencing subassemblies and displays each having a structure in which all of the addressed pixel electronic circuitry including an optimized capacitance and including isolation devices where utilized, are located at one electrode side of each pixel electrode combination. The structure includes the subdivision of one pixel electrode into at least two spaced apart side-by-side electrode segments opposite a common electrode. The displays include light influencing material disposed between the segmented and common electrodes which form a first capacitance. A second capacitance is formed electrically in parallel with the first capacitance. The second capacitance can include an additional capacitance electrode formed separated from the segmented electrode by an insulating layer. The electrode segments further can include at least one isolation device coupled to at least one of the segments which facilitates selective excitation of the pixel elements and applied potential reversal across the electrodes during alternate display frames. The displays have an increased manufacturing yield, optimized capacitance and increased isolation. Also disclosed is a method of making the subassemblies and displays.
