| 20090145347 | INDICATION MEMBER - An indication member having an original structural color, is provided with an indication layer to cause a structural color change irreversibly by receiving a stimulus from the outside so as to exhibit another structural color different from the original structural color. The another structural color obtained by the structural color change is not reversed to the original structural color. | 06-11-2009 |
| 20090147339 | STRUCTURAL COLOR DISPLAY - Disclosed is a structural color display including: (a) a pattern forming member which forms a plurality of cells each lined up in two dimension; and (b) a light transmissive image display sheet comprising a color showing layer which shows a structural color, the light transmissive image display sheet being faced to the pattern forming member, wherein each cell is independently controlled to reflect a light from a light source corresponding to an image pattern to be displayed, provided that the reflected light is made to enter in the image display sheet from a side facing the pattern forming member by a predetermined incident angle corresponding to the cell. The pattern image forming member comprises the element having a plurality of microscopic mirrors arranged in a rectangular array and being individually rotated. | 06-11-2009 |
| 20090147347 | STRUCTURAL COLOR DISPLAY - Disclosed is a structural color display including: (a) a pattern forming member which forms a plurality of cells each lined up in two dimension; and (b) a light transmissive image display sheet comprising a color showing layer which shows a structural color, the light transmissive image display sheet being laminated on the pattern forming member, wherein each of the cells is independently controlled to switch to a light reflective state or to a light absorptive state corresponding to an image pattern to be displayed, provided that the light absorptive state is a state in which a light which enters in the cell through the image display sheet is absorbed; and the light reflective state is a state in which a light which enters in the cell through the image display sheet is reflected and the reflected light is made to enter in a region of the image display sheet corresponding to the cell. | 06-11-2009 |
| 20090237800 | DISPLAY MEMBER - Provided is a display member containing: an display layer which exhibits a structural color and contains spherical bodies and a matrix; and a reflective interface which reflects a light transmitting through the display layer, wherein the reflective interface is made between the display layer and a reflective interface forming layer which is provided in contact with the display layer; and a refractive index of the spherical bodies na, a refractive index of the matrix nb and a refractive index of the reflective interface forming layer nc satisfy the following Formulas (1) and (2): | 09-24-2009 |
| 20100152065 | PRODUCTION METHOD OF PARTICLE ARRAY - A method of producing a particle array is disclosed, comprising allowing monodisperse particles to be arrayed in an aqueous medium containing a monomer to form a colloidal crystal exhibiting a structural color and then polymerizing the monomer to form a polymer. | 06-17-2010 |
| 20100266946 | IMAGE FORMING METHOD - A color particle is disclosed, comprising a color-exhibitive piece which comprises microparticles for structural color and a matrix and is dispersed in a binder resin, wherein the color particle meets the following requirement: | 10-21-2010 |
