title = "Low power drivers for liquid crystal display technologies",
abstract = "A driver circuit can be used to drive a matrix display device, such as a liquid crystal display, that includes a plurality of pixels 16 disposed in rows 12 and columns 14. A first switch 328 has a current path coupled between a high voltage node (e.g., VS) and a group of pixels 16. As an example, the group of pixels 16 can be a row 12 or a column 14. A second switch 326 has a current path coupled between a low voltage node (e.g., ground) the group of pixels 16. A third switch 322 has a current path coupled between an inductive storage element 34 and the group of pixels. The inductive storage element 34 is coupled to an intermediate voltage node (e.g., VS/2) with a voltage between the voltage at the high voltage node and the voltage at the low voltage node",
