The filtration module 50 of touching display screen 100, also can produce touching signals while having the filtering functions of existing product, makes this touching display screen 100 have touch-control and Presentation Function concurrently.
Following emphasis describes filtration module 50, and filtration module 50 comprises top glass substrate 53 and is sequentially laminated on transparency conducting layer 52 and the filter layer 51 of top glass substrate 53 lower surface.Wherein, this transparency conducting layer 52 is for generation of touching signals.In one embodiment, first form transparency conducting layer 52 at top glass substrate 53 lower surface, then filter layer 51 is attached to the lower surface of transparency conducting layer 52.Be appreciated that and also first can form filter layer 51 at top glass substrate 53 lower surface, then form transparency conducting layer 52 at the lower surface of filter layer 51.
Filter layer 51 comprises shading matrix 511 and is scattered in the colored light-filtering units 513 in shading matrix 511.Shading matrix 511 is formed by black light-proofness material usually.Colored light-filtering units 513 is formed by red, green or blue light resistance material, and the filter unit 513 of three kinds of colors is uniformly distributed in shading matrix 511.The 26S Proteasome Structure and Function of described filter layer 51 can be identical with existing product, do not repeat them here.
See also Fig. 2 and Fig. 3, transparency conducting layer 52 comprises matrix 522 and is filled in the electrical-conductive nanometer silk thread 523 in matrix 522.This matrix 522 is the transparent feel photopolymer resin of solidification.
In one embodiment, the interlaced overlap joint of electrical-conductive nanometer silk thread 523 and being uniformly distributed in matrix 522 entire scope, makes the overall homogeneous conductive of transparency conducting layer 523.Electrical-conductive nanometer silk thread 523 part exposes the side surface of matrix 522 away from top glass substrate 53, makes this surface conduction, thus is convenient to be connected with perimeter circuit and spread out of touching signals.
The diameter range of electrical-conductive nanometer silk thread 523 is 10 nanometer ~ 1000 nanometers, and length range is 0.1 micron ~ 50 microns.The diameter of electrical-conductive nanometer silk thread 523 is less than the visual width of living human eye, thus ensures visually-clear.Electrical-conductive nanometer silk thread 523 can be easy to prepare for gold nanowires line, silver nanoparticle silk thread, Cu nanowire line, aluminium nanometer silk thread, carbon nanometer silk thread etc. and have the conductive thread of better electric conductivity.Consider the adhesion of transparency conducting layer 52 and electrical-conductive nanometer silk thread 523 can preferably in filling substrate 522 time, the thickness of transparency conducting layer 52 is preferably 0.1 micron ~ 50 microns.The square Standard resistance range of transparency conducting layer 52 can be 0.1 Ω/ ~ 500 Ω/.Transparency conducting layer 52, compared to the electric conductivity of ITO conductive layer, is more suitable for for making as panel computer (pad), all-in-one (All in one, AIO), touch-control product that notebook (Notebook) equidimension is larger.
The electric conductivity of transparency conducting layer 52 is relevant to the diameter of electrical-conductive nanometer silk thread 523 and electrical-conductive nanometer silk thread 523 distribution density, and diameter is larger, and distribution density is larger, then electric conductivity is better, and namely sheet resistance is lower.But the diameter of electrical-conductive nanometer silk thread 523 is larger, distribution density is larger, the transmitance of transparency conducting layer 52 is lower.Therefore, in order to ensure the balance of transmitance and electric conductivity, the sheet resistance of transparency conducting layer 52 is preferably 50 Ω/ ~ 200 Ω/.
Refer to Fig. 4, in another embodiment, electrical-conductive nanometer silk thread 523 is only distributed in the certain thickness range areas of matrix 522 away from top glass substrate 53 side, thus transparency conducting layer 52 ' forms conduction region 524 and nonconductive regions 525 in a thickness direction.Conduction region 525 thickness is greater than conduction region 524 thickness, and the thickness of conduction region 524 is 10 ~ 1000 nanometers, and the thickness of nonconductive regions 525 is 0.5 ~ 50 micron.Nonconductive regions 525 can improve the adhesive strength of transparency conducting layer 52 ', thus can reduce the thickness of conduction region 524 as much as possible.Owing to only needing to carry out patterning to conduction region 524 during transparency conducting layer 52 ' patterning, after the thickness of conduction region 524 reduces to contribute to reducing patterning, drafting department and background portion obtain difference in height, avoid the outward appearance that easily caused by identification due to pattern not good.
