Abstract:
A field emission display device comprising:a plurality of row drivers, each for driving a row voltage signal over a respective row line, one at a time, during a row on-time window, wherein row on-time windows are synchronized by a horizontal synchronization clock signal; anda plurality of column drivers of first, second and third colors, each column driver coupled to a respective column line and for time multiplexing thereon different voltages during a first part and a second part of each row on-time window, each column driver comprising:a first error compensation circuit for dividing an N-bit data value into a first (N-1) bit data value having negative error;a second error compensation circuit for dividing said N-bit data value into a second (N-1) bit data value having positive error;a selector circuit for providing output data as follows: for each first part, said N-bit data value is provided; and for each second part, said first (N-1) bit data value and second (N-1) bit data value are provided, respectively, for frames of each consecutive frame pair; anda digital to analog converter for converting said output data into analog voltage signals for driving said respective column line.
