Color image display panel and driving method thereof
First Claim
1. An image display panel having, in a multilayer structure, a first light modulating layer and a second light modulating layer each comprising a periodical planar arrangement of a plurality of light modulating elements for modulating a color or a brightness of an incident light in response to an input signal, wherein the arrangement period of the light modulating element in the first light modulating layer is smaller than the arrangement period of the light modulating element in the second light modulating layer.

11. A method for driving an image display panel having, in a multilayer structure, a first light modulating layer comprising a periodical planar arrangement of a plurality of light modulating elements for modulating a brightness of an incident light in response to an input signal and a second light modulating layer comprising a periodical planar arrangement of a plurality of light modulating elements for modulating a color of an incident light in response to an input signal, wherein a spatial frequency component of a drive signal applied to the first light modulating layer is higher than a spatial frequency component of a drive signal applied to the second light modulating layer.
-
12. A method for driving an image display panel having at least two light modulating layers each comprising a periodical planar arrangement of a plurality of light modulating elements for modulating a color or a brightness of an incident light in response to an input signal, wherein, in a display area where a drive signal applied to said light modulating element for modulating the brightness contains a large portion of high spatial frequency components, a drive signal applied to said light modulating element for modulating the color is so modified as to display a relatively brighter color.

13. A method for driving an image display panel having at least two light modulating layers of a light modulating layer comprising a periodical planar arrangement of a plurality of light modulating elements for modulating a brightness of an incident light in response to an input signal and a light modulating layer comprising a periodical planar arrangement of a plurality of light modulating elements for modulating a color, wherein such a drive as to compensate a position offset between said brightness modulating layer and said color modulating layer is conducted.
