Abstract:
A display apparatus having a plurality of pixels, each pixel having an ON state and an OFF state, each pixel of the display apparatus comprising:a top substrate;a bottom substrate disposed parallel to the top substrate;a first select electrode provided on one of the top substrate and the bottom substrate;a second select electrode, adjacent to the first select electrode, provided on the same substrate;a data electrode provided on the opposite substrate;a source of alternating current (AC) signal having first and second phases;a first switch connected to the source of AC signal and to the first select electrode for selectively applying the first phase or the second phase of the AC signal to the first select electrode;a second switch connected to the source of AC signal and to the second select electrode for selectively applying the first phase or the second phase of the AC signal to the second select electrode; anda third switch connected to the source of AC signal and to the data electrode for selectively applying the first phase or the second phase of the AC signal to the data electrode,wherein, when the same phase is applied to both the first and second select electrodes, the phase of the AC signal applied to the data electrode determines the state of the pixel and when the phase applied to the first select electrode differs from the phase applied to the second select electrode the state of the pixel remains unchanged.
