Claim:
1. A level shifter for a display comprising: a first row line control circuit to control a first row line of the display; a second row line control circuit to control a second row line of the display; a third row line control circuit to control a third row line of the display; a fourth row line control circuit to control a fourth row line of the display; a first switch coupled to the first and the second row line control circuits for sharing charge stored on the first row line with the second row line; a second switch coupled to the third row line control circuit and the fourth row line control circuit for sharing charge stored on the third row line with the fourth row line; and a single resistor coupled between the first switch and the second row line control circuit and the single resistor coupled between the second switch and the fourth row line control circuit, wherein a slope of charge and discharge voltages on the row lines are substantially identical.
