Abstract
An exemplary method for manufacturing a substrate structure includes steps of: providing a substrate; forming a plurality of isolated protrusions on the substrate; depositing ink onto the protrusions; and solidifying the ink to form a plurality of ink layers on the respective protrusions. This method can create ink layers with uniform thickness. A substrate structure having ink layers is also included.
Claims16
A substrate structure, comprising:
- a substrate;
- a black matrix comprising a plurality of banks formed on the substrate, the black matrix defining a plurality of isolated spaces and the plurality of isolated spaces being defined by the plurality of banks and the substrate;
- and
- a plurality of isolated transparent protrusions wholly and directly arranged on the substrate, each of the isolated transparent protrusions being positioned and fully filling each of the isolated spaces, each of the isolated transparent protrusion comprising a top surface and a side surface, the side surfaces of adjacent isolated transparent protrusions being spaced, each protrusion having a greater thickness than a thickness of the black matrix, thus the top surfaces of adjacent isolated transparent protrusions being spaced, wherein the thickness is measured normal to the substrate, and an ink layer is formed only on a whole top surface of each protrusion, so that a pattern formed by the ink layer is same as a pattern formed by the plurality of isolated transparent protrusions.

A color filter, comprising:
- a substrate;
- a black matrix formed on the substrate, the black matrix defining a plurality of isolated spaces;
- and
- a plurality of isolated transparent protrusions wholly and directly arranged on the substrate, each of the isolated transparent protrusions being positioned and fully filling each of the isolated spaces, each of the isolated transparent protrusion comprising a top surface and a side surface, the side surfaces of adjacent isolated transparent protrusions being spaced, each protrusion having a greater thickness than a thickness of the black matrix, thus the top surfaces of adjacent isolated transparent protrusions being spaced, wherein the thickness is measured normal to the substrate, and an ink layer is formed only on a whole top surface of each protrusion, so that a pattern formed by the ink layer is same as a pattern formed by the plurality of isolated transparent protrusions.
