Abstract:
1. A driving apparatus for outputting a driving signal to drive an electro-phoretic display, comprising: a driving signal generator, for generating a plurality of periodic alternative current signals and a plurality of direct current signals; a temperature sensor, generating a temperature parameter by sensing an environment temperature; and a selector, coupled to the driving signal generator and the temperature sensor, the selector selecting one of the periodic alternative current signals or one of the direct current signals as the driving signal according to the temperature parameter, wherein the driving signal is a common voltage for the electro-phoretic display, and the driving signal is dynamically changed among the plurality of periodic alternative current signals and the plurality of direct current signals in response to the temperature parameter when the electro-phoretic display is in operation, so as to improve a driving time related to the electro-phoretic display and thus increasing the performance of the electro-phoretic display.
