Method of making color filter arrays by transferring colorant material
First Claim
1. A method of making a color filter array on a first substrate having an array of pixels, comprising the steps of:
- a) depositing and patterning a photoresist layer on the first substrate to form selected openings over pixels in the array;
b) providing a colorant layer having a heat transferable colorant material on a second substrate and positioning the second substrate such that the heat transferable colorant material is in transferable relationship but spaced a distance from the first substrate;
c) heating the second substrate sufficiently to cause substantially all of the heat transferable colorant material to transfer across the spaced distance to the patterned photoresist layer on the first substrate; and
d) removing the patterned photoresist layer leaving behind the heat transferable colorant material in the position of the selected openings over the pixels in the array.

Abstract
A method of making a color filter array on a first substrate having an array of pixels is disclosed. The method includes depositing and patterning a photoresist layer on the substrate layer to form selected openings over pixels in the array; providing a colorant layer having a transferable colorant material on a second substrate and positioning the second substrate such that the transferable colorant material is in transferable relationship with the first substrate; transferring the colorant material to the photoresist layer on the first substrate; and removing the patterned photoresist layer leaving behind the colorant material in the position of the openings over the selected pixels.
