But but optical filter box 200 has touch control operation and filtering functions, makes touch display screen 100 have touch display function simultaneously.Touch display screen can be the LCDs of straight-down negative or side entering type light source.
Refer to Fig. 2 to Fig. 5, expression be 200 4 different embodiment of optical filter box.Optical filter box 200 in above-mentioned four embodiment includes substrate 210, the first impression glue-line 220, the first conductive layer 230, filter layer 240, the second impression glue-line 250 and the second conductive layer 260.Substrate 210 is the transparent insulation material, as glass, is specifically as follows sillico aluminate glass and calcium soda-lime glass, through the plasma treatment rear surface, has good cohesive force.General, the thickness range of substrate 210 can be 0.1mm～0.5mm.
The first impression glue-line 220 covers the surface in substrate 210, and the first impression glue-line 220 offers the first groove 222 away from a side of substrate 210.The groove that the first groove 222 is mesh shape, mesh shape can be preset to required figure as required.The first conductive layer 230 is embedded at the first impression glue-line 220, comprises a plurality of the first conductive patterns 232, and 232 of a plurality of the first conductive patterns are provided with interval, so that a plurality of the first conductive pattern 232 mutually insulateds.The first conductive pattern 232 comprises some conductive grids that intersected to form by conductive thread 270, and conductive thread 270 intersects to form grid node, and described conductive thread 270 is contained in described the first groove 222.Conductive thread 270 is solidify to form by the conductive material that is filled in the first groove 222, and conductive material can be at least one in metal, carbon nano-tube, Graphene, organic conductive macromolecule or ITO.In other embodiments, can also offer the first groove 222 in a side of the first impression glue-line 220 close substrates 210.

In the present embodiment, adjacent two conductive patterns arrange interval, with mutually insulated.As shown in Figure 7 and Figure 8, the schematic diagram of the different modes at the interval of adjacent two the first conductive patterns 232 or adjacent two the second conductive patterns 262.As shown in Figure 7, in one embodiment, expression be the width that the interval width of adjacent two the first conductive patterns 232 or adjacent two the second conductive patterns 262 is a filter unit.Now can, by full line or permutation conductive thread 270 disappearances, be cut off.As shown in Figure 8, in other embodiments, can also adjacent two the first conductive patterns 232 or the interval width of second conductive pattern 262 of adjacent two be 0.5 μ m～50 μ m.Now can be by conductive thread 270 marginal portion disappearances be cut off.In other embodiments, the width that interval width that also can adjacent two the first conductive patterns 232 is a filter unit, the interval width of adjacent two the second conductive patterns 262 is 0.5 μ m～50 μ m.
Refer to Fig. 6, in the present embodiment, conductive thread 270 is straight line, curve or broken line.When conductive thread 270 can be for difformity, reduced production requirement.
As shown in Figure 9, the projection of each conductive grid on filter layer 240 of the first conductive layer 230 and the second conductive layer 260 accommodates a filter unit.Because the conductive thread 270 of the first conductive layer 230 and the second conductive layer 260 is all aimed at gridline, so the filter unit held is integer, quantity is one.Because each grid cell is to there being a conductive grid, so the density of conductive grid is larger, electric conductivity is better.
As shown in Figure 10 to Figure 12, the projection of each conductive grid on filter layer 240 of the first conductive layer 230 and the second conductive layer 260 accommodates at least two filter units.Because the conductive thread 270 of the first conductive layer 230 and the second conductive layer 260 is all aimed at gridline, so the filter unit held is integer, quantity is at least two, can require and the requirement of the coating weight of conductive material decides the filter unit quantity of holding according to the resistance to conductive layer.
Now can be divided into three kinds of situations, take is laterally X-axis, and the direction of vertical transverse is Y-axis.As shown in figure 10, only, on X-direction, at least two filter units are held in the projection of each conductive grid on filter layer 240 of the first conductive layer 230 and the second conductive layer 260.As shown in figure 11, only, on Y direction, at least two filter units are held in the projection of each conductive grid on filter layer 240 of the first conductive layer 230 and the second conductive layer 260.As shown in figure 12, on X-axis and Y direction, at least two filter units are held in the projection of each conductive grid on filter layer 240 of the first conductive layer 230 and the second conductive layer 260 simultaneously.
