Abstract
A method for manufacturing a liquid crystal (LC) display includes determining an amount of an LC material to be used in the LC display, determining a silane material to be mixed with the LC material and an amount of the silane material to be mixed with the LC material based on the LC material and the amount of the LC material, mixing the amount of the silane material with the amount of the LC material to generate an LC mixture, and heat treating the LC mixture in contact with a display substrate to bond at least a portion of the silane material to one or more surfaces of the display substrate, such that the silane material acts as a surfactant. The amount of the silane material may constitute at least 0.8% of the LC mixture by weight.

A liquid crystal (LC) mixture, comprising:
- an amount of an LC material;
- and
- an amount of a surfactant material,
- such that a ratio of the amount of the surfactant material to the amount of the LC material, by weight, is between and including 0.8:99.2 and 1.2:98.8.
A method for manufacturing a liquid crystal (LC) display, comprising:
- determining an amount of an LC material to be used in the LC display;
- based on the LC material and the amount of the LC material, determining:
- a surfactant material to be mixed with the LC material;
- and
- an amount of the surfactant material to be mixed with the LC material;
- mixing the amount of the surfactant material with the amount of the LC material to generate an LC mixture, such that a ratio of the amount of the surfactant material to the amount of the LC material, by weight, is between and including 0.8:99.2 and 1.2:98.8;
- and
- heat treating the LC mixture in contact with a display substrate to bond at least a portion of the surfactant material to one or more surfaces of the display substrate.
A liquid crystal (LC) display, comprising:
- an LC material;
- a display substrate configured to contain the LC material;
- and
- a surfactant material bonded to one or more surfaces of the display substrate and positioned between the one or more surfaces and the LC material,
- the surfactant material being present in an amount such that a ratio of the amount of the surfactant material to the amount of the LC material, by weight, is between and including 0.8:99.2 and 1.2:98.8.
