Abstract: A method of driving a cholesteric liquid crystal display (LCD) panel by applying at least first, second, and third voltages to cholesteric liquid crystal cells of the cholesteric LCD panel is provided. The method includes alternately applying the first and second voltages to apply the third voltage, which is given by the root-mean-square value of the first and second voltages, to the cholesteric liquid crystal cells.

Abstract: A raw panel for a liquid crystal display. A first substrate includes first electrodes opposing a second substrate including second electrodes. A plurality of main walls having a predetermined height are arranged in a striped pattern between first and second substrates to define a plurality of channels. The channels include sets of pixels, each set formed by three neighboring channels. First sub-walls are mounted at a predetermined distance from a first end line and between the main walls defining first channels in sets the first channels each having at least two separate spaces. Second sub-walls are mounted at a predetermined second distance from the first end line and between the main walls defining second channels in sets, the second channels each having at least two separate spaces. The raw panel is opened at the first end line and at a second end line opposite the first end line.

Abstract: There is provided a method of driving a cholesteric liquid crystal display (LCD) panel by sequentially applying a selection line voltage to individual scan electrode lines and simultaneously applying data signals to all data electrode lines in order to select a state of each cholesteric liquid crystal cell according to a given gray scale level. Each selection time, during which the selection line voltage is applied to a certain scan electrode line and simultaneously the data signals are applied to all of the data electrode lines, is constant. Each selection time is divided into a first part time and a second part time. A low selection line voltage is applied to a relevant scan electrode line during the first part time. A high selection line voltage having a level different from that of the low selection line voltage is applied to the relevant scan electrode line during the second part time. A data pulse having a width corresponding to either the first part time or the second part time is applied to all of the data electrode lines at different time points according to the gray scale level of a relevant cholesteric liquid crystal cell during the selection time.
