Abstract
Provided is a technology for controlling an electrowetting cell. The electrowetting cell may be controlled by applying a preset first voltage to the electrowetting cell, measuring a first circuit parameter between any one side surface and a conductive liquid disposed in the electrowetting cell and determining whether a reset second voltage is to be applied to the electrowetting cell based on the measured first circuit parameter.
Claims19
An apparatus for controlling an electrowetting cell, the apparatus comprising:
- a voltage application unit configured to apply a preset first voltage to the electrowetting cell;
- a measurement unit configured to measure a first circuit parameter between a conductive liquid in the electrowetting cell and any one side surface of the electrowetting cell;
- and
- a processor configured to predict a second circuit parameter based on the preset first voltage and to determine whether to apply a reset second voltage to the electrowetting cell, based on a difference between the measured first circuit parameter and the predicted second circuit parameter.
A method of controlling an electrowetting cell, the method comprising:
- applying a preset first voltage to the electrowetting cell;
- measuring a first circuit parameter between any one side surface of the electrowetting cell and a conductive liquid disposed in the electrowetting cell;
- predicting a second circuit parameter based on the preset first voltage;
- and
- determining whether a reset second voltage is to be applied to the electrowetting cell, based on a difference between the measured first circuit parameter and the predicted second circuit parameter.
A non-transitory computer-readable recording medium having embodied thereon a program executing a method of controlling an electrowetting cell, the method comprising:
- applying a reset first voltage to the electrowetting cell;
- measuring a first circuit parameter between any one side surface of the electrowetting cell and a conductive liquid disposed in the electrowetting cell;
- predicting a second circuit parameter based on the preset first voltage;
- and
- determining whether a reset second voltage is to be applied to the electrowetting cell based on a difference between the measured first circuit parameter and the predicted second circuit parameter.
