Description
Technical field
The present invention relates to polaroid technical field, specially a kind of polaroid with capacitance touching control function.
Background technique
Traditional upper polaroid is not no touch function, has the display module of capacitance touching control function to need at present additional
Paste touch function piece (referred to as external hanging type scheme), or by liquid crystal display glass plated film realize touch function (such as
Incell/oncell is known as embedded scheme).
Wherein, additionally patch touch function piece will increase a few road bonding process, and itself existing plated film on TFT glass, then increase
Add touch-control pattern plated film, yield can reduce；The product of incell/oncell structure is applied at present, and coated glass is for line one
As in 6 generations hereinafter, efficiency is also high without package plated film.
Summary of the invention
The purpose of the present invention is to provide a kind of polaroids with capacitance touching control function, to solve under polaroid
TAC plates nanometer silverskin to realize touch function, and the necessary polaroid of touch-control display module is combined into one with touch function piece, is subtracted
The problem of lacking the bonding process of external hanging type scheme and improving whole process rate.
To achieve the above object, the invention provides the following technical scheme:
A kind of polaroid with capacitance touching control function, including TAC film one, the OCA film from top to bottom set gradually
One, PVA film, OCA film two, TAC film two and OCA film four are disposed with nano silver between the TAC film two and OCA film four
Film, OCA film three and TAC film three, and nanometer silverskin is disposed in proximity to two side of TAC film.
Compared with prior art, the beneficial effects of the present invention are:
The present invention passes through the setting for increasing a nanometer silverskin, OCA film three and TAC film three, reduces external hanging type scheme touch-control
The bonding process for showing product, reduces embedded scheme TFT coating film on glass process, effectively reduces product cost, improves and produces
Product competitiveness, is highly promoted.
Detailed description of the invention
Fig. 1 is traditional polaroid structure schematic diagram in the prior art；
Fig. 2 is the polaroid structure schematic diagram with touch function of the invention.
In figure: 1 TAC film one, 2 OCA films one, 3 PVA films, 4 OCA films two, 5 TAC film two, 6 nanometers of silverskin, 7 OCA
Film three, 8 TAC films three, 9 OCA films four.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of technical solution referring to FIG. 1-2:
A kind of polaroid with capacitance touching control function, including TAC film 1, the OCA film from top to bottom set gradually
One 2, PVA film 3, OCA film 24, TAC film 25 and OCA film 49 are disposed between TAC film 25 and OCA film 49 and receive
Rice silverskin 6, OCA film 37 and TAC film 38, and nanometer silverskin 6 is disposed in proximity to 25 side of TAC film.
As shown in Figure of description 2, TAC, that is, Triafol T, OCA, that is, transparent optical cement, PVA are polyvinyl alcohol, this
It is the material of conventional polarizers a bit, from top to bottom, the polaroid film with capacitance touching control function is by TAC film 1, OCA film one
2, PVA film 3, OCA film 24, TAC film 25, nanometer silverskin 6, OCA film 37, TAC film 38, OCA film 49.Wherein OCA film 1,
OCA film 24, OCA film 37, OCA film 49 are all optical cements, play cementation；The effect of TAC film 1 is protection PVA film 3
And product surface is protected not to be scraped off, the effect of PVA film 3 is polarization light, that is, the functional layer of polaroid, TAC film 25
Effect is protection PVA film 3 and does substrate to nanometer silverskin 6, and the effect that 6 layers of nanometer silverskin is to realize touch function, TAC film 38
Effect be that the surface of nanometer silverskin 6 is protected not scratched.
It is the structure of traditional polaroid as shown in Figure of description 1, being equivalent to has capacitance touching control in of the invention
The polaroid of function removes this three layers of nanometer silverskin 6, OCA film 37 and TAC film 38 in Figure of description 1, and wherein this six layers
Effect it is identical with the role of polaroid of the invention.
Working principle: the polarizing function of the polaroid with touch function and the working principle and biography of capacitance touching control function
System polaroid, the working principle of capacitance touching control functional sheet are the same.Polarisation principle: PVA film 3 has two iodine to absorption function
Molecule makes iodine molecule ordered arrangement on PVA film by stretching, and being formed has uniform two light polarizing films to absorbent properties.Touch-control
Principle: induction electrode pattern and driving electrodes pattern are located on nanometer silverskin 6, driving electrodes transmitting electric field line to induction electrode,
Touch-control IC can scan by column sense wire and measure its interelectrode capacitance change；When finger or close touch medium, touch-control IC
The capacitance on touch point between driving electrodes and induction electrode is predicted rapidly to change, and then confirms the position of touch-control.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
