    Abstract: The present invention discloses a REPEATED-SCAN driving method, which applies to a field sequential color liquid crystal display, wherein each sequential-color cycle (31) of the multiplex-scan signal (30) has at least two stages of scans (32) to increase the luminous fluxes of all colors of backlights (20) and bring closer the total amounts of fluxes, whereby is achieved higher color saturation and better flux uniformity between the rows. Further, the method of the present invention controls the backlights (20) to form dark stages (21) between the intervals respectively of two different colors of the backlights (20) and controls the dark stage (21) to coincide with a color-mixing interval, which is caused by response delay of liquid crystal, to prevent from color distortion caused by color mixing. Therefore, the present invention can generate the pure colors and the designed derived colors accurately.

    Abstract: An electrochemical display unit capable of being simplified in unit construction and reduced in cost with a simple matrix drive implemented. An electrochemical display unit that effects displaying by using electrochemical depositing/melting of a metal. The unit is driven by a simple matrix drive system, and uses as a threshold value in a simple matrix drive a deposition over-voltage at which metal ions deposit as a metal. The drive voltage is up to two times the deposition over-voltage. The electrochemical display unit has a transparent electrode and a counter electrode, and displays images by depositing/melting of a metal on the transparent electrode, the potential difference between a metal deposited on the transparent electrode and the counter electrode being set to be less than a deposition over-voltage. Ideally, the same metal as one deposited on the counter electrode is used.

    Abstract: A liquid crystal display device (A1) includes a plurality of pixels arranged in a matrix, a plurality of first electrodes (2R, 2G), a plurality of second electrodes (3) intersecting the first electrodes, a liquid crystal layer arranged between the first electrodes and the second electrodes, a color filter directly or indirectly covering each of the first electrodes, and a driver (7) for supplying image display signals to the first electrodes and the second electrodes. The first electrodes are connected to scanning signal supply terminals of the driver to periodically receive a scanning signal. The second electrodes are connected to control signal supply terminals of the driver to selectively receive a control signal. The driver causes the liquid crystal layer to be in either an ON state or an OFF state by supplying the scanning signal and the control signal to the first electrodes and the second electrodes, respectively.
