Liquid crystal, color membrane substrates, polaroid, touch control layer, touch base plate and pass through the ripple of the double faced adhesive tape film λ Nian Jie with the polaroid/4
Piece, the touch control layer are located between the wave plate of film λ/4 and the touch base plate.
The λ wave plates of film 1/4 are that the touch control layer is formed at by way of sputter, make to be formed in touch control layer organic thin
Film layer.
Glassy layer that the touch control layer includes setting gradually, black matrix layer, conductive film layer, organic insulator, metal level, the
One inorganic insulation layer, metal sputtering layer and the second inorganic insulation layer.
The conductive film layer is indium tin oxide transparent conducting film.
First inorganic insulation layer is formed at by way of sputter on the metal level.
The material of first inorganic insulation layer is SiNx.
The metal sputtering layer is formed at by way of sputter on first inorganic insulation layer.
