Patent ID: 8223141

Claim:
A method for driving a display having an array of pixels arranged in a plurality of columns and a plurality of rows, said method comprising: receiving a first data bit intended to be displayed on one of said pixels in one of said rows of said array, said first data bit having a first bit significance; defining a first loading period during which said first data bit is loaded into said storage element and data bits of said first bit significance are loaded into respective storage elements of each of a plurality of said rows of said display; loading said first data bit into a storage element of said pixel, the value of said first data bit controlling a voltage asserted on a pixel electrode of said pixel whenever said first data bit is stored in said storage element; turning on a light source to illuminate said pixel while said data bit is stored in said storage element; receiving a second data bit intended to be displayed on said pixel after said first data bit is displayed on said pixel, said second data bit having a second bit significance; defining a second loading period during which said second data bit is loaded into said storage element and data bits of said second bit significance are loaded into said respective storage elements of each of said plurality of said rows of said display; loading said second data bit into said storage element of said pixel, the value of said second data bit controlling said voltage asserted on said pixel electrode whenever said second data bit is stored in said storage element; keeping said light source turned on while said first data bit is replaced by said second data bit by said loading of said second data bit into said storage element; receiving a third data bit intended to be displayed on said pixel after said second data bit, said third data bit having a third bit significance; defining a third loading period during which said third data bit is loaded into said storage element and data bits of said third bit significance are loaded into said respective storage elements of each of said plurality of said rows of said display; loading said third data bit into said storage element of said pixel, the value of said third data bit controlling the voltage asserted on said pixel electrode whenever said third data bit is stored in said storage element; turning said light source off during said third loading period; and turning said light source on after said third loading period; and wherein the time period during which said first data bit is stored in said storage element exceeds the duration of said first loading period; the time period during which said second data bit is stored in said storage element exceeds the duration of said second loading period; and the time period during which said light source is turned on and said third data bit is stored in said storage element is less than the duration of said third loading period.
