pulse width modulated waveform providing a dynamically changing optical output based on the current digital information made available a check at the diamond 190 may provide a desired transition in each pulse width modulated waveform driving the associated display element as each comparator 92 fig2 of the plurality of comparators 92 1 through 92 n may compare the global digital information i e the count with the local digital information if determined to be equal the pulse width modulated waveforms may be turned u201c off u201d at block 192 conversely if determined to be different the pulse width modulated waveforms may be kept u201c on u201d at block 194 to digitally drive pixels from pulse width modulated waveforms a control logic 200 e g for the global drive circuit 24 of fig1 and a pixel logic 205 e g for each local drive circuit of the plurality of local drive circuits 1 1 30 a through n 1 30 b of fig1 consistent with one embodiment of the present invention are shown in fig6 for the ease of the presentation a hypothetical dotted line 210 functionally distinguishes the control logic 200 from the pixel logic 205 according to one embodiment to provide digital information entails sending a pixel value to each display element at block 215 using the control logic 200 a corresponding pixel value may be received at each display element.
