▎ 摘  要

NOVELTY - The method involves taking a temporary substrate, arranging a borneol layer on the temporary substrate, and coating a precoating layer on the borneol layer. A die is taken with multiple salient points, multiple concave points corresponding to the salient points are formed on the precoating layer, and dried and cured. The graphene salient points are arranged in the concave points and necessary graphical processing is carried out to form a graphene touch control element. One side of the pre-coated graphene touch element is adhered with a display screen substrate, and heated to sublimate the borneol layer, and the temporary base material is separated from the precoating layer. A blocking layer is formed on one side of the pre-coating layer, which is far away from the graphene touch control element, so as to obtain the graphene touch control film of the display screen. USE - Preparation method of touch control film of display screen graphene. Uses include but are not limited to organic electroluminescence (EL) display screen, LCD screen, plasma display panel (PDP) screen, electrophoretic display (EPD) screen and field emission display (FED) screen. ADVANTAGE - The method enables forming the barrier layer on one side of the pre-coating far away from the graphene touch control element to obtain the touch control film of the display screen graphene, thus avoiding damage of the formed graphene touch element graphene preparing the touch film, and controlling flatness of the temporary base material in an efficient manner. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural view of a mold of a preparation method of touch control film of display screen graphene wherein it comprises the following steps.
