Ruling misalignment, it is also possible to alignment.When ruling misalignment in conductive thread 34 with shading matrix, for
Ensure the light transmission of optical filter module 60, and then the colour rendering of guarantee display screen, the conductive thread of conductive grid
The live width of 34 is in 500nm～5 μ m, so that conductive grid is the most transparent.
In one embodiment, the conductive thread 34 in the first conductive pattern 222 and the second conductive pattern 224
Just the shading resin in optical filter module or ink, i.e. conductive thread 34 are put down at shading resin or ink place
Projection on face just fully falls on shading resin or ink, and conductive thread 34 is blocked resin or ink hides
Gear, does not so interfere with the light transmission rate of display screen, and the thickness of conductive thread 34 require also without requiring
In visually-clear, as long as the thickness of conductive thread 34 is less than shading resin or the thickness of ink wire.
As shown in fig. 4 a, the conductive grid of the first conductive pattern 222 and the second conductive pattern 224 can be

One grid cell of lattice is just to the multiple filter unit grids on light shield layer.
Wherein, as shown in Figure 4 b, the conductive thread 34 of conductive grid can be straight line.Such as Fig. 4 c and 4d
Shown in, the conductive thread 34 of conductive grid can also be the grid cell of curve, i.e. conductive grid can be nothing
Regular figure, as long as conductive thread is blocked resin or ink blocks.Equally, it is also possible to each conduction
One grid cell of grid is just to the multiple filter unit grids on light shield layer.
The structure of conductive layer 220 can be the structure being formed arbitrarily touch sensible.
Refer to Fig. 5, when conductive layer 220 is individual layer multipoint configuration, the first conductive pattern of stamping structure
222, the second conductive pattern 224 manufacturing process can be such that
(1) polarizer substrate material 210 is provided；
(2) conductive layer 220 is prepared on a surface in polarizer substrate material 210, and electric layer 220 includes that first leads
Electrical pattern 222 and the second conductive pattern 224.
In the present embodiment, at polarizer substrate material 210 plated surface last layer metal level 212, then coating glue becomes,
Then by etching formed the first conductive pattern 222 and the second conductive pattern 224 first conductive pattern 222 with
The second spaced formation of conductive pattern 224 has the conductive layer 220 of induction structure.
(3) on conductive layer 220, it is coated with glue, forms coated glue layer 230.Coated glue layer 230 will conduction
Layer 220 is completely covered.In the present embodiment, preferably use UV glue.
The first conductive pattern 222 and the second conductive pattern 224 that are formed by coated metal be can be equally used for
Bridging structure.
Referring to Fig. 6 and Fig. 7, in another embodiment, conductive layer 220 can also be for bridging structure.Lead
Electric layer 220 can also include that conducting bridge 226, conducting bridge 226 are located on the first conductive pattern 230, leads
Be formed with insulating barrier 228 between electric bridge 226 and the first conductive pattern 222, conducting bridge 226 be electrically connected in
Two the second conductive patterns 224 of the first conductive pattern 222 both sides.In the present embodiment, conducting bridge 226 is embedded
In coated glue layer 230, the insulating barrier 228 between conducting bridge 226 and the first conductive pattern 222 is glue-line.
Conducting bridge 226 can be transparent conductive material, is conducive to improving the light transmittance of polaroid module 200.
In the present embodiment, conducting bridge 226 can be formed grid lines by conductive thread 34 interconnection.Further,
The first conducting block 26 and the second conducting block 26 ' can be respectively provided with, due to first at the two ends of conducting bridge 226
The surface area of conducting block 26 and the second conducting block 26 ' is more than conducting bridge 226, contacts with the second conductive pattern 224
Face is bigger, and may be electrically connected to the second corresponding conductive pattern 224 at least two lead the first conducting block 26
Electrical filament line 34, the second conducting block 26 ' is electrically connected at least two conductions of the second corresponding conductive pattern 224
Silk thread, to ensure the validity (if a wherein broken string, still can turning on of other) of electrically overlap joint.
Conducting bridge 226 can also disposably imprint the grid conducting bridge 226 of arch for being imprinted with being formed,
First can also obtain the mode of consent with photolithographic exposure and be initially formed the consent of conducting block, then impressing forms lattice portion
Groove, forms the conducting bridge 226 with network and conducting block by etching.
Present invention have the advantage that
(1) the polaroid module in the present invention can realize touch control operation and outgoing polarization light function simultaneously, as
An indispensable assembly in display screen, time in display screen, can directly make display screen have touch-control merit
Can, it is not necessary to assemble a touch-screen the most on a display screen, not only contribute to reduce the thickness of electronic product, simultaneously
Also it is greatly saved material and assembly cost.
(2) with grid molding touch control conductive pattern in the present invention, can be by the width of Controling network ruling and close
Degree reaches visually-clear, the material that conductive pattern is selected by tradition only with transparent material expand to all suitably
Conductive material, when conductive pattern selects metal material, can reduce greatly resistance to reduce the energy consumption of touch-screen.
(3) conductive pattern pass through pattern imprint shape one-shot forming grid, patterned etch (film forming-exposure-
Development-etching) technique disposably turn and sow group impressing mould, every a piece of conductive pattern all can once be embossed into
Type, mesh shape and pattern one-shot forming, it is not necessary to every equal patterned etch of a piece of conductive pattern, be greatly simplified
Manufacturing process, it addition, be targetedly embossed grooves to be filled with conductive material after pattern imprint,
Rather than the formation of whole of base material etches again, so can save substantial amounts of conductive material, particularly use relatively
Expensive conductive material, during such as ITO, cost savings are the most obvious.
(4) contact conductor in conductive pattern is network, it is simple to scratch when filling conductive material,
Conductive material is the most retained the most not to be blown off, for nanometer silver paste, when sintering,
Agglomeration effect will not be produced produce the ping-pong ball scattered and cause the second contact conductor fracture.
(5) conductive thread shading resin or ink projection in the plane just fully fall in shading resin
Or on ink, conductive thread is blocked resin or ink blocks, and does not so interfere with the light transmission rate of display screen,
The thickness of knot conductive thread requires also without requiring in visually-clear, as long as the thickness of knot conductive thread is less than
Shading resin or the thickness of ink wire, can be substantially reduced the technological requirement of conductive grid shaping, with fall
Low production cost.
(6) polaroid in the present invention is organic flexible base material, is applied to volume to volume technique, it is adaptable to large quantities of
Amount produces.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for this area
Those of ordinary skill for, without departing from the inventive concept of the premise, it is also possible to make some deformation and
Improving, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with appended
Claim is as the criterion.
