Carve) technique disposably turn sow a group impressing mould, per a piece of conductive pattern can an imprinting moulding, mesh shape and pattern
One-shot forming, without per a piece of conductive pattern equal patterned etch, enormously simplify manufacturing process, in addition, pattern imprint it
After be that targetedly embossed grooves are filled with conductive material, rather than the whole face of base material forms and etched again, can so save
Substantial amounts of conductive material, conductive material costly particularly is being used, during such as ITO, cost savings are quite obvious.
(4) contact conductor in conductive pattern is network, is easy to be scratched when filling conductive material, conductive material
Easier be retained is not blown off wherein, meanwhile, for nanometer silver paste, in sintering, agglomeration effect generation will not be produced
The ping-pong ball that scatters and cause second electrode wire breaking.
(5) conductive thread shading resin or ink projection in the plane just fully fall in shading resin or ink
On, conductive thread is blocked by shading resin or ink, does not interfere with the light transmission rate of display screen so, ties the thickness of conductive thread
It is required that also without requiring in visually-clear, as long as the thickness of knot conductive thread is less than shading resin or the thickness of ink wire is
Can, the technological requirement that conductive grid is molded can be substantially reduced, to reduce production cost.
(6) polarizer substrate material in the present invention is organic flexible base material, raw suitable for high-volume applied to volume to volume technique
Production.
