Addressing schemes for electronic displays
First Claim
1. An electronic display comprising an electro-optic material having a plurality of pixels, and separate first, second and third sets of addressing means for addressing said pixels, each of said pixels being associated with one addressing means in each of said three sets, such that any specific pixel of the display can be addressed by application of signals within predetermined ranges to each of the three addressing means associated with said specific pixel, the pixels being arranged in a plurality of sub-arrays, each pixel within any specific sub-array being associated with one of the first and second sets of addressing means, the third set of addressing means having the form of a plurality of switching means, at least one of said switching means being associated with each of said sub-arrays, the switching means associated with each sub-array having an off state, in which signals on at least one of the first and second sets of addressing means are prevented from reaching the associated sub-array, and an on state, in which signals from both the first and second sets addressing means are permitted to reach and address the associated sub-array, and wherein each sub-array comprises a discrete page, the pages formed by the plurality of sub-arrays being stacked on top of each other so that the entire display forms a multi-page electronic book.

Abstract
An electronic display comprises an electro-optic material (preferably an electrophoretic medium) having a plurality of pixels, and separate first, second and third sets of addressing means for addressing these pixels. Each of the pixels is associated with one addressing means in each of the three sets, such that addressing of any specific pixel requires application of signals within predetermined ranges to each of the three addressing means associated with the specific pixel being addressed. The display may be in the form of a multi-page electronic book.

19. A method of addressing an electronic display, the method comprising:
- providing an electro-optic material having a plurality of pixels;
providing first, second and third sets of addressing means for addressing said pixels, each of said pixels being associated with one addressing means in each of said three sets, the pixels being arranged in a plurality of sub-arrays, each pixels within any specific sub-array being associated with one of the first and second sets of addressing means, the third set of addressing means having the form of a plurality of switching means, at least one of said switching means being associated with each of said sub-arrays, the switching means associated with each sub-array having an off state, in which signals on at least one of the first and second sets of addressing means are prevented from reaching the associated sub-array, and an on state, in which signals from both the first and second sets of addressing means are permitted to reach and address the associated sub-array, and wherein each sub-array comprises a discrete page, the pages formed by the plurality of sub-arrays being stacked on top of each other so that the entire display forms a multi-page electronic book; and
applying predetermined signals to the three addressing means associated with a specific pixel, thereby addressing said pixel.
