Abstract:
1. A color cholesteric liquid crystal display device, comprising: a color cholesteric liquid crystal display panel with a plurality of color sub-pixels divided into a first portion and a second portion, wherein the first portion of sub-pixels has a first color and the second portion of sub-pixels has a second color different from the first color, and wherein the sub-pixels have a first displaying state and a second displaying state; a driving module configured to selectively provide a voltage on the first portion of the sub-pixels, the second portion of the sub-pixels, or both the first and second portions of the sub-pixels; and an input element; configured such that when a given sub-pixel is in the first displaying state and without the voltage applied, pressure from the input element transforms the sub-pixel from the first displaying state to a second displaying state, when the given sub-pixel is in the second displaying state and without the voltage applied, the sub-pixel is maintained in the second displaying state when pressure from the input element is applied, when the given sub-pixel is in the first displaying state and with the voltage applied, the sub-pixel is maintained in the first displaying state when pressure from the input element is applied, and when the given sub-pixel is in the second displaying state and with the voltage applied, pressure from the input element transforms the sub-pixel from the second displaying state to a first displaying state.
