Be appreciated that when using backlight as polarized light source, as the OLED polarized light source, without lower polaroid 10, only need upper polaroid 60 to get final product.Structure and the function of the lower polaroid 10 of the present embodiment, TFT electrode 20, Liquid Crystal Module 30, public electrode 40, diaphragm 50, upper polaroid 60 can be identical with existing product, do not repeat them here.
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, filter layer 220, the first impression glue-line 230, the first conductive layer 240, the second impression glue-line 250 and the second conductive layer 260.Wherein substrate 210 comprises first surface 212 and second surface 214, and first surface 212 and second surface 214 are oppositely arranged.The material of substrate 210 can be sillico aluminate glass and calcium soda-lime glass, processes rear surface through Plasma and has good cohesive force.General, the thickness range of substrate 210 can be 0.1mm～0.5mm.
The first impression glue-line 230 is arranged at the side of filter layer 220 away from first surface 212, and the first impression glue-line 230 offers the first groove 232 away from a side of first surface 212.The groove that the first groove 232 is mesh shape, mesh shape can be preset to required figure as required.The first conductive layer 240 is embedded at the first impression glue-line 230, comprises a plurality of the first conductive patterns 242, and 242 of a plurality of the first conductive patterns are provided with interval, so that a plurality of the first conductive pattern 242 insulation.The first conductive pattern 242 comprises some the first conductive grids, and the first conductive grid is intersected to form by the first conductive thread 2422, and the first conductive thread 2422 intersects to form grid node, and described the first conductive thread 2422 is contained in described the first groove 232.The first conductive thread 2422 is solidify to form by the conductive material that is filled in the first groove 232.Conductive material can comprise at least one in metal, carbon nano-tube, Graphene, organic conductive macromolecule and ITO.In other embodiment, also can offer the first groove 232 near a side of first surface 212 at the first impression glue-line 230.

Wherein, the live width of the wherein one in the first conductive thread 2422 and the second conductive thread 2622 is 0.2 μ m～5 μ m, and another one all drops on gridline in the projection of filter layer 220.
As shown in Figure 5, what mean is that the first conductive thread 2422 drops on gridline in the projection of filter layer 220, and the live width of this first conductive thread 2422 is less than the live width of gridline, the distance that the live width of the second conductive thread 2622 is 0.2 μ m～5 μ m and adjacent two grid nodes is 50 μ m～800 μ m.In other embodiment, as shown in Figure 4, the live width of the first conductive thread 2422 can also equal the live width of gridline.When optical filter box 200 is applied to product, be generally the second surface 214 of substrate 210 towards the user, more easily by user's naked eyes, seen and affect user's experience sense so be embedded at the second conductive layer 260 of the second impression glue-line 250.So all drop on gridline and live width does not exceed gridline by the first conductive thread 2422 in the projection of filter layer 220, the live width of the second conductive thread 2622 is 0.2 μ m～5 μ m, makes visually-clear, is conducive to improve user's experience sense.In other embodiment, the projection that the second conductive thread 2622 can also be arranged in to filter layer 220 all falls within on gridline, further improves user's experience sense.
The distance of adjacent two grid nodes is 50 μ m～800 μ m.When the distance of grid node, when larger, the density of conductive grid is less, and now light permeable rate wants large, and cost also can be low, but resistance can be larger.When the distance of grid node more hour, the density of conductive grid is larger, resistance is less, but transmitance reduces, the consumption of conductive material is also larger simultaneously, so that cost is higher.Therefore considering cost, transmittance and resistance factors, be traditionally arranged to be 50 μ m～800 μ m by the grid node spacing.
