Abstract
An apparatus to fabricate a color filter includes an inkjet head movably installed over a substrate on which a plurality of pixels are formed to discharge ink of predetermined colors into the pixels, and a porous member movably installed over the pixels filled with the ink discharged from the inkjet head to form a solvent ambient around the ink filled within the pixels due to evaporation of a solvent filled in the porous member to reduce a drying speed of the ink.
Claims29
An apparatus to fabricate a color filter, the apparatus comprising:
- an inkjet head movably installed over a substrate to discharge ink of predetermined colors into pixels formed on the substrate;
- and
- a porous member movably installed over the pixels to form a solvent ambient around the ink discharged into the pixels due to an evaporation of a solvent in the porous member to reduce a drying speed of the ink discharged into the pixels.
A system to fabricate a color filter, comprising:
- a transparent substrate having a plurality of pixels;
- an inkjet printhead to discharge ink into the pixels;
- and
- a porous member having a solvent to form a solvent ambient over the ink discharged into the pixels to generate ink layers having uniform thicknesses in the corresponding pixels.
A system to fabricate a color filter, comprising:
- an inkjet printhead to discharge ink;
- and
- a porous member to supply a solvent toward the discharged ink.
A color filter having color pixels, comprising:
- a substrate having an edge portion and an inner portion;
- a plurality of first pixels formed in the edge portions of the substrate;
- a plurality of second pixels formed in the inner portion of the substrate;
- ink filled in the corresponding first and second pixels to form first and second color pixels using a solvent applied around the ink filled in the corresponding first and second pixels, such that the first color pixels and the second color pixels have substantially the same height.
A method of fabricating a color filter, comprising:
- discharging ink into a plurality of pixels of a transparent substrate using an inkjet printhead;
- and
- supplying a solvent toward the ink filled in the pixels.
A method of making a color filter having color pixels, comprising:
- forming a plurality of first pixels in edge portions of a substrate;
- forming a plurality of second pixels in an inner portion of the substrate;
- filling ink in the corresponding first and second pixels to form first and second color pixels;
- and
- applying a solvent around the ink filled in the corresponding first and second pixels.
