Abstract
The present invention provides a driving apparatus, the driving apparatus is used for outputting a driving signal to drive an electro-phoretic display, and the driving apparatus includes a driving signal generator, a temperature sensor, and a selector. The driving signal generator generates a plurality of periodic alternative current signals and a plurality of direct current signals. The temperature sensor generates a temperature parameter by sensing an environment temperature. The selector is coupled to the driving signal generator and the temperature sensor. The selector selects one of the periodic alternative current signals or one of the direct current signals as the driving signal according to the temperature parameter. The driving signal is a common voltage for the electro-phoretic display, and when one of the periodic alternative current signals is selected as the driving signal, an amplitude of the driving signal is varied with the environment temperature.
