Patent ID: 8884940

Claim:
A system for driving an array of display elements, the system comprising: at least one capacitor; at least one charging supply line; a first overdrive line configured to output a positive overdrive voltage to the array of display elements; a second overdrive line configured to output a negative overdrive voltage to the array of display elements; a first plurality of drive lines, each configured to supply a positive drive voltage to the array of display elements; a second plurality of drive lines, each configured to supply a negative drive voltage to the array of display elements; a first plurality of switches configured to selectively couple the at least one charging supply line to the at least one capacitor; a second plurality of switches, wherein each of the second plurality of switches is configured to selectively couple one of the first plurality of drive lines to the at least one capacitor; a third plurality of switches, wherein each of the third plurality of switches is configured to selectively couple one of the second plurality of drive lines to the at least one capacitor; a fourth plurality of switches configured to selectively couple the at least one capacitor to at least one of the first and second overdrive lines; and a controller configured to activate a first subset of the four pluralities of switches while deactivating a second subset of the four pluralities of switches, wherein the positive and negative overdrive voltage outputs are sequentially generated in a time sequence.
