▎ 摘　　要

NOVELTY - The method involves modifying a substrate surface such that the substrate surface is formed as hydrophilic. Graphene composite nano silver is printed on a substrate by adopting an ink jet printing mode to form a grid of touch control electrodes. A hydrophilic organic silicon antifogging transparent coating is coated on polyurethane material of the substrate. The hydrophilic organic silicon antifogging transparent coating is solidified at 90-110 degrees centigrade. Coating thickness of the hydrophilic organic silicon antifogging transparent coating is about 1-3 microns. USE - Method for preparing a touch screen. ADVANTAGE - The method enables ensuring strong flexibility effect, and increasing adhesive force of the substrate, and reducing preparation cost, and improving manufacturing precision of the touch control electrodes, and obtaining high light transmitting rate, and realizing printing operation in an effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a touch screen display device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a touch screen.
