See also Fig. 1 to Fig. 5, a kind of graphical nesa coating 100 comprises substrate 110, first conductive layer 120 and second conductive layer 130, and substrate 110 comprises first surface 112 and second surface 114, and first surface 112 and second surface 114 are oppositely arranged.First conductive layer 120 is located at the first surface 112 of substrate, comprise first conduction region 122 and first insulation layer 124, first conduction region 122 comprises by the formed some metal grills of metal wire, and the metal wire slope of first conduction region 122 near horizontal probability density greater than near probability density longitudinally.Second conductive layer 130 comprises second conduction region 132 and second insulation layer 134, second conduction region 132 comprises by the formed some metal grills of metal wire, second conductive layer 130 and 120 stacks of first conductive layer and space and mutual insulating on the thickness direction of substrate 110, formed stack metal grill after the stack evenly distributes in all angles, and the close probability density longitudinally of metal wire slope is greater than close horizontal probability density.Wherein, metal grill is the flush type metal grill, by offering groove or offer groove on the hypothallus surface on substrate 110 surfaces, filling metal material again in groove forms, perhaps directly at substrate 110 metal wire that the surface is coated with, oven dry obtains being interspersed, carry out compacting again, obtain the flush type metal grill.
Above-mentioned graphical nesa coating is coordinate plane with the plane at substrate 110 places, laterally is X-axis, vertically is Y-axis.Metal wire slope in the metal grill of first conduction region 122 that obtains near horizontal probability density greater than near probability density longitudinally, that is to say first conduction region 122 near the quantity of the metal wire of X-axis greater than the quantity near Y-axis.Metal wire slope in the metal grill of second conduction region 132 near probability density longitudinally greater than near horizontal probability density, that is to say second conduction region 132 near the quantity of the metal wire of Y-axis greater than the quantity near X-axis.And because first conductive layer 120 is different with the metal wire probability density of second conductive layer 130 on same direction, after first conductive layer 120 and 130 stacks of second conductive layer, the stack metal grill distribution probability of whole conducting film becomes evenly to distribute, avoid grid and the repetition of LCD meshing rule, eliminated Moire fringe.The said random grid of present embodiment can be alveolate texture.
Seeing also Fig. 5, is first conductive layer 120 and second conductive layer, 130 stacks probability distribution schematic diagram afterwards.As shown in the figure, because the metal wire slope of first conduction region 122 near horizontal probability density greater than near probability density longitudinally, the close probability density longitudinally of the metal wire slope of second conduction region 132 is greater than close horizontal probability density, so when the slope of the metal wire in the metal grill of first conduction region 122 is in rising trend, the slope of the metal wire in the metal grill of second conduction region 132 is on a declining curve, after first conductive layer 120 and second conductive layer 130 superposeed, the slope integral body of the metal wire after the stack is the level of state, and namely the stack metal grill distribution probability of whole conductive layer is evenly distributed.
See also Fig. 4 and Fig. 6, in the present embodiment, the type of random grid is the irregular polygon random grid of isotropic, will be the angular distribution that example is analyzed the metal wire of its stack metal grill below with the random grid of 5mm*5mm area.
Among the embodiment as shown in Figure 4, random grid comprises 4257 line segments altogether.That adds up every line segment obtains one-dimension array θ (1) ~ θ (4257) with X-axis angle θ; And then with 5 ° be interval layout, be divided into 36 angular interval with 0 ~ 180 °; Drop on each interval interior probability in the statistics line segment, obtain one group of array p (1) ~ p (36), as shown in Figure 6; Subsequently according to the standard deviation computing formula:
N is 36 in the formula, and can obtain standard deviation s is 0.26%, and average probability p is 2.78%.Thus
As seen the grid line of above-mentioned random grid is very even in angular distribution, can effectively avoid the generation of Moire fringe.When being attached at the LCD surface, will can not produce Moire fringe by the described graphical nesa coating of present embodiment.
See also Fig. 1, in present embodiment, second conductive layer 130 is arranged at the second surface 114 of substrate 110, is oppositely arranged with first conductive layer 120.By carry out the groove impression at hypothallus, filled conductive material in groove then, form first conductive layer 120 and second conductive layer 130, first conductive layer 120 that to make at last and second conductive layer 130 are fabricated into first surface 112 and the second surface 114 of substrate respectively, form after the stack the graphical nesa coating that grid immediately is evenly distributed on all angles.Wherein, hypothallus is the thermoplastic polymer layer.The visible light transmissivity of first conductive layer 120 and second conductive layer 130 is all greater than 88.6%.Certainly, in other embodiment, also first conductive layer 120 and second conductive layer 130 can be superimposed upon the same side of substrate 110, and the each interval insulation, satisfying the conducting film of different types of structure, thereby be applied to the touch-screen of different types of structure.
When planning grid, by intercepting after will stretching in a lateral direction for the grid of making first conductive layer, intercepting after will stretching in a longitudinal direction for the grid of making second conductive layer, the equal grid of preceding area obtains and stretches; According to the grid photoetching that designs; Again according to the figure mfg. moulding die of photoetching; Impress with mould again, obtain groove; Filled conductive material in groove obtains some flush type metal grills.Behind the stretching grid, the area of single metal grid has increased, so first conductive layer that obtains and the second conductive layer transmitance have increased.And the metal wire of the metal grill of first conductive layer that obtains is more near the quantity of X-axis, and the metal wire of the metal grill of second conductive layer is more near the quantity of Y-axis.Because the metal wire near a certain direction is more many, the unilateal conduction performance on this direction is more good, so the X-axis of first conductive layer conducts electricity very well, the Y-axis of second conductive layer conducts electricity very well.
