Connection.So, the more remote first electrode of distance controlling chip distance, its corresponding track lengths are longer, and impedance is bigger.In order that
Obtain different first electrodes and there is identical impedance, the mesh-density for arranging second area in each first electrode is identical, and sets
Put and the control chip bigger first electrode of distance, the density of the grid cell in its first area is bigger, to reduce different the
The resistance difference of one electrode, improves touch control detection precision.In embodiments of the present invention, for same first electrode, first is arranged
Region is different from the layout of second area, to avoid the problem of moire fringes.It is rectangle to arrange the grid cell in second area, and
The first cabling and the second cabling for forming rectangular-shaped grid cell is not overlapped with pixel coloured silk film unit, hidden by black-matrix layer
Hide the first cabling and the second cabling in second area；The grid cell arranged in first area is rhombus, now first is walked
Line and the second cabling out of plumb, the two is overlapped on the direction of first substrate with pixel coloured silk film unit.In such manner, it is possible to
It is prevented effectively from the problem of moire fringes.In same first electrode, can be with the setting the 3rd between first area and second area
Region, and net of the grid cell density in the 3rd region in the grid cell density and second area of first area is set
Between lattice cell density, so that grid cell density smooth variation in same first electrode, it is ensured that display quality.
