Color filter on array with integrated black matrix for high-ppi lcd

An LCD comprising:

• a backplane that electrically controls an array of pixels, wherein the backplane comprises:
• a bottom substrate dimensioned to display the array of pixels;
• a COA coupled to a top of the bottom substrate such that the COA enables a filtering of colors for the array of pixels;
• and
• at least one black matrix coupled to the COA to partition sub-pixels of the array of pixels, wherein the black matrix is dimensioned as a spacer electrically connecting a layer on a proximal side of the COA and a layer on a distal side of the COA;
• and
• a set of display layers coupled to a top of the backplane such that the array of pixels is viewed through the set of display layers.

A method of manufacturing an LCD backplane comprising:

• dimensioning a bottom substrate to display an array of pixels;
• coupling a COA to a top of the bottom substrate such that the COA enables a filtering of colors for the array of pixels;
• and
• coupling at least one black matrix to the COA to partition sub-pixels of the array of pixels, wherein the black matrix is dimensioned as a spacer electrically connecting a layer on a proximal side of the COA and a layer on a distal side of the COA.
