Method of making color filter arrays by transferring colorant material

摘要

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.
