Abstract

Devices, methods and systems for controlling cells of an electrochromic display are disclosed. A device is connected to each cell of the display which is to be controlled to drive each cell according to a charging state associated with the cell; and to provide a characteristic of a selected cell to a sensor. The device can operate in a sense and a programming mode. In sense mode the device determines the characteristic of a selected cell; and in programming mode the device sets the charging state of the cells. Methods and systems for controlling display elements generally are also disclosed in which a varying drive signal (such as a sawtooth signal) is applied to the display element to increase the charge transfer over what would occur using a constant drive signal.
