Abstract:
1. An apparatus for driving an electric field driven cell array including a plurality of electric field driven cells, wherein each of the electric field driven cells includes a first electrode, a second electrode, and a third electrode, which are provided on a substrate and insulated from one another, and an actuator movable between the first electrode and the second electrode, wherein the first electrode and the second electrode are spaced from each other with a predetermined distance, and the third electrode is disposed below the first electrode, the apparatus including: a common voltage supply unit for supplying a common voltage to the first electrode of the electric field driven cell; a gate driver for supplying a gate voltage to the second electrode of the electric field driven cell by a gate line; and a data driver for supplying a data voltage to the third electrode of the electric field driven cell by a data line, wherein the actuator is positioned adjacent to the first electrode or the second electrode in accordance with a state of the gate voltage and the data voltage, wherein if a high level gate voltage drops to a low level gate voltage, the gate driver maintains a voltage level between the high level gate voltage and the low level gate voltage for a certain time period before the gate voltage reaches the low level thereof.
