Description
Technical Field
The utility model relates to a polaroid technical field specifically is a polaroid with capacitanc touch function.
Background
The conventional upper polarizer has no touch function, and a display module having a capacitive touch function requires an additional touch function sheet (referred to as an external scheme) or a film coated on the liquid crystal display glass to realize the touch function (for example, an cell/oncell is referred to as an embedded scheme).
The additional touch function sheet pasting can increase a plurality of pasting procedures, the TFT glass is coated with films, and then the touch pattern coating is added, so that the yield can be reduced; at present, the coated glass generation line of the product applying the acell/oncell structure is generally below 6 generations, and the efficiency is not high when the roll coating is carried out.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a polaroid with capacitanc touch-control function to solve TAC and plate nanometer silver membrane under the polaroid and realize the touch-control function, unite two into one the necessary polaroid of touch-control display module assembly and touch-control function piece, reduce the laminating process of outer hanging scheme and improve the problem of holistic processing procedure yield.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a polaroid with capacitanc touch-control function, includes TAC film one, OCA film one, PVA film, OCA film two, TAC film two and OCA film four that from top to bottom set gradually it is three with TAC film three to set gradually between TAC film two and the OCA film four, and the nanometer silver membrane sets up in being close to two one sides of TAC film.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses an increased setting three of nanometer silver membrane, OCA membrane and TAC membrane, reduced the laminating process of outer hanging scheme touch-control display product, reduced embedded scheme TFT glass coating film process, effectively reduced product cost, improved product competitiveness, be worth very much promoting.
Drawings
FIG. 1 is a schematic diagram of a conventional polarizer in the prior art;
fig. 2 is a schematic structural diagram of the polarizer with touch function according to the present invention.
In the figure: the film comprises a first 1 TAC film, a first 2 OCA film, a first 3 PVA film, a second 4 OCA film, a second 5 TAC film, a 6 nano silver film, a third 7 OCA film, a third 8 TAC film and a fourth 9 OCA film.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution:
the utility model provides a polaroid with capacitanc touch-control function, includes TAC film 1, OCA film 2, PVA film 3, OCA film two 4, TAC film two 5 and OCA film four 9 that from top to bottom set gradually, has set gradually nanometer silver-colored membrane 6, three 7 of OCA film and three 8 of TAC film between TAC film two 5 and OCA film four 9, and nanometer silver-colored membrane 6 sets up in being close to TAC film two 5 one side.
As shown in fig. 2 of the specification, TAC is triacetylcellulose, OCA is transparent optical adhesive, PVA is polyvinyl alcohol, which are materials of conventional polarizers, and polarizer films with a capacitive touch function include, from top to bottom, a TAC film i 1, an OCA film i 2, a PVA film 3, an OCA film ii 4, a TAC film ii 5, a nano silver film 6, an OCA film iii 7, a TAC film iii 8, and an OCA film iv 9. Wherein the OCA film I2, the OCA film II 4, the OCA film III 7 and the OCA film IV 9 are all optical glue and have a bonding effect; the TAC film I1 is used for protecting the PVA film 3 and protecting the surface of a product from being scratched, the PVA film 3 is used for polarizing light rays, namely a functional layer of a polarizer, the TAC film II 5 is used for protecting the PVA film 3 and providing a substrate for the nano silver film 6, the nano silver film 6 layer is used for achieving a touch function, and the TAC film III 8 is used for protecting the surface of the nano silver film 6 from being scratched.
As shown in the accompanying drawing 1, the polarizer with capacitive touch function is a conventional polarizer, and the three layers of the nano silver film 6, the three layers of the OCA film 7 and the three layers of the TAC film 8 in the accompanying drawing 1 are removed from the polarizer with capacitive touch function of the present invention, wherein the functions of these six layers are completely the same as the functions of the polarizer of the present invention.
The working principle is as follows: the working principle of the polarizing function and the capacitive touch function of the polarizer with the touch function is the same as that of the traditional polarizer and the capacitive touch function sheet. The principle of polarization: the PVA film 3 has iodine molecules having a dichroic absorbing function, and the iodine molecules are aligned in order on the PVA film by stretching to form a polarizing film having a uniform dichroic absorbing property. Touch principle: the sensing electrode pattern and the driving electrode pattern are positioned on the nano silver film 6, the driving electrode emits electric field lines to the sensing electrode, and the touch IC scans the sensing lines row by row to measure the capacitance variation between the electrodes; when a finger or a touch medium approaches, the touch IC rapidly detects the capacitance change between the driving electrode and the sensing electrode at the touch point, and then confirms the touch position.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
