Title: Liquid crystal display element and halftone display method thereby
Inventor: SHINJO KATSUHIKO
IPC: G02F1/1343
Filed: 1992-12-28
Abstract: PURPOSE:To obtain a high gradation number with a simple constitution by allowing an area inverted by polarization corresponding to a halftone signal applied to a pair of electrodes to be appeared as a specific striped area, and displaying a halftone while utilizing the area. CONSTITUTION:The halftone is displayed by manifesting the area inverted by polarization corresponding to the halftone signal applied to a pair of electrodes which regulate a liquid crystal cell as the striped area almost in parallel with the layer direction of the chiral smectic phase of ferroelectric liquid crystal. For example, in a picture element 1, plural domains 3 inverted by polarization in a state on the other side out of the bistable states of a liquid crystal molecule manifest in striped shape in the area 2 set in an initial state that is the state on one side out of the bistable states of the liquid crystal molecule. When the domain 3 is appeared in the striped shape, probability in which the same domain appears when a signal with the same wave is applied can be increased. In addition to that, the length and density of the striped shape domain 3 are changed linearly corresponding to the peak value and pulse width of the signal. Therefore, it is possible to perform the control of permeability satisfactorily and to obtain a method suitable for gradation display.
