Abstract
Embodiments of the present invention operate at least two microshutter electrodes with different voltages from each other for displaying grays. Also, a data voltage is applied to the microshutter electrodes after an initialization voltage when the display device has hysteresis characteristics such that erroneous operation due to the hysteresis characteristics is eliminated. As described herein, the display device including the microshutter electrodes may display subdivided grays.
Claims20
A display device comprising:
- an insulation substrate;
- a pixel electrode formed on the insulation substrate, and made of a transparent conductive material;
- an insulating layer disposed on the pixel electrode;
- and
- at least two microshutter electrodes, wherein the microshutter electrodes are:
- disposed on the insulating layer,
- made of a non-transparent conductive material for blocking light,
- electrically connected to each other so that a same voltage is applied to both, and
- opened and closed by applying different voltages.
A method for driving a display device that includes a pixel electrode made of a transparent conductive material;
- at least two microshutter electrodes made of a non-transparent conductive material for blocking light, electrically connected to each other so that the same voltage is applied to each, and opened and closed through different voltages;
- a gate line;
- a data line;
- and a thin film transistor connected to the gate line, the data line, and the pixel electrode or the microshutter electrodes;
- the method comprising:
- applying a gate-on voltage to the gate line;
- and
- alternately applying a reset voltage and a data voltage to the data line, wherein:
- the reset voltage and the data voltage are applied for at least respective portions of a time during which the gate-on voltage is applied, and
- the reset voltage is applied before the data voltage.
