Description

  The present invention relates to a method for manufacturing a touch sensor element of a polarizing plate and a polarizing device, and more particularly, a thinning process for manufacturing a touch sensor element on a polarizing plate of a display and a thinning process thereof. The present invention relates to a polarizing device with a touch function.

  In a display such as a general liquid crystal display (LED), the orientation of liquid crystal molecules and the twist of liquid crystal molecules can be changed by changing the electric field formed by the upper and lower electrode layers of the liquid crystal layer in the liquid crystal display by the voltage of the driving chip. In this case, a state in which the light is transmitted through the backlight source or a state in which the light is not transmitted through the backlight is selected. Thereafter, color display is performed by changing the color of each pixel through a color filter.

  In the liquid crystal display, two upper and lower polarizing plates are used on both upper and lower sides of the liquid crystal layer. The function of the polarizing plate is to convert unpolarized light from the backlight light source into polarized light. The liquid crystal display adjusts the light-dark effect by using polarized light and the torsional characteristics of liquid crystal molecules to control whether or not to allow light to pass.

A conventional display module with a touch function will be described as an example shown in FIG. In a display module with a touch function, normally, other touch pad modules are combined, and a detection circuit detects a position where the user touches the display panel. The display module with a touch function shown in FIG. 1 is a liquid crystal display module combined with a touch pad module 101.

  As shown in FIG. 1, the display module with a touch function includes a liquid crystal layer 105 sandwiched between an upper substrate 104 and a lower substrate 106. An upper polarizing plate 102 is bonded to the upper substrate 104 with an optical adhesive 103. A lower polarizing plate 108 is bonded below the lower substrate 106 with an optical adhesive 107.

  A light source 111 is provided below the display module with a touch function, and a touch pad module 101 is provided above the display module with a touch function. The display module with a touch function is electrically connected to a driving chip 109 for controlling the voltage to the liquid crystal electrode. The driving chip 109 is electrically connected to the circuit board 110 and drives the display by the system. A lower polarizing plate 108 in a liquid crystal display (for example, a TFT LCD) converts a non-polarized light generated by the light source 111 into a unidirectional polarized light. The polarization angle of the lower polarizing plate 108 and the upper polarizing plate 102 is 90 °. After the light beam passed through the liquid crystal layer 105, the polarization property of the light beam was changed by the change of the electric field. Thereafter, the upper polarizing plate 102 determines the brightness level of each pixel.

  In order to provide the above-described conventional display module with a touch function, a method of bonding the touch pad module 101 to the upper surface of the panel is used. However, such a conventional display module with a touch function has disadvantages such as non-thinning and high cost.

  In order to improve the drawbacks of the conventional display module with a touch function, the present invention provides a manufacturing method in which a touch sensor element is directly formed on the surface of a polarizing plate.

The plurality of first electrode wirings are electrically connected to the plurality of first electrodes that are not connected to each other. The plurality of second electrode wirings are electrically connected to the plurality of second electrodes connected to each other.

  Since there is a wiring of an electrode that is not connected at a place where jump wiring is performed between the first electrodes, a jump connection insulating layer is formed by coating an insulating material between the first electrodes that are not connected. Thereafter, the jump connection insulating layer is coated with a second transparent conductive material, and the second transparent conductive material is photocured (for example, ultraviolet light) or thermally cured to thereby form the first lead on the jump connection insulating layer. Form a line. The first electrodes that are not connected are connected by the first lead wire.

  The manufacturing method of the touch sensor element of the polarizing plate which concerns on this invention is for manufacturing the polarizing device by which the touch sensor element was provided in the surface.

These elements constitute the polarizing device according to the present invention.

In addition, since the polarizing device manufactured by the manufacturing method of the present invention can realize a thinner in-cell display with a touch function, the conventional one glass solution (OGS) The thickness of the display is thinner than that of the) -type display, and the thickness can be effectively reduced. In addition, the object of cost reduction can be achieved by simplifying the process.

Moreover, the polarizing device which concerns on this invention is a polarizing device with a touch function manufactured by the manufacturing method of the touch sensor element of the polarizing plate which concerns on this invention. Since the polarizing device according to the present invention has a touch function (for example, capacitive type) and a polarizing effect at the same time, a touch sensor built-in display module that does not require a separate touch panel can be realized. it can.

  Please refer to FIG. 2 and FIGS. 3A to 3E. FIG. 2 shows a flowchart of a method for manufacturing a touch sensor element for a polarizing plate according to the present invention. 3A to 3E show a manufacturing process of the manufacturing method of the touch sensor element of the polarizing plate according to the present invention.

 Hereinafter, the flowchart of the manufacturing method of the touch sensor element of the polarizing plate which concerns on this invention is demonstrated. In step S201, a base material having a polarization function is prepared. The base material having a polarizing function is a polarizing plate used for a display module. A polarizing plate 301 illustrated in FIG. 3A has high light transmittance (light transmittance is approximately 85% or more) and can be applied to a flat panel display. The surface of the polarizing plate 301 is provided with at least a blocking layer and a curing treatment layer for blocking air and water.

  In step S203, a first transparent conductive material, which is the conductive material 303 shown in FIG. 3B, is formed on the substrate surface by a coding method such as a dry coating process or a wet coating process. Since the base material is used for a polarizing plate in a display module, the first transparent conductive material is preferably a conductive material having a high light transmittance of 85% or more.

  In step S203, the coating method is preferably a precision coating method. For example, a conductive material having a high light transmittance is uniformly applied on a substrate having a polarization function. The precision coating method is, for example, a dry process or a wet process, and the film thickness is preferably 0.01 μm to 10 μm, and the error is preferably within 15%. As the first transparent conductive material, for example, indium tin oxide (ITO), nano silver (nano silver), nano copper (nano Cu), conductive polymer, carbon nanotube (graphene), graphene, bromide Materials such as silver (AgBr) and indium gallium zinc oxide (IGZO) may be used. In addition, the conductive polymer is a chemical derivative doped, such as polyaniline, polyaniline derivative, polythiophene, polythiophene derivative, and the like. It is not limited.

  In the case where the first transparent conductive material is formed by a dry process, for example, a method such as sputtering, evaporation, chemical vapor deposition (CVD), or the like can be used. On the other hand, when the first transparent conductive material is formed by a wet process, for example, slot die, gravure, dipping, inject-printing, spray coating, etc. The method can be used.

  A conventional display with a capacitive touch function uses a two-layer sensor element (sensor electrodes in the X and Y directions are provided in different layers), whereas in the present invention, a single-layer sensor element is used. . That is, in the present invention, since the sensor electrodes in the X direction and the Y direction are installed in the same layer, the layout of the electrode wirings in different directions must be devised in the manufacturing process.

  In step S205, by patterning the first transparent conductive material formed on the substrate surface, the substrate has a plurality of sensing areas made of a transparent conductive material (that is, the first transparent conductive material). A plurality of signal wiring areas are formed. The sensing area and the signal wiring area are the sensor electrode and its wiring in the display with a touch function. As shown in FIG. 4A, the first electrode 11 and the second electrode 21 are simultaneously provided in the X direction and the Y direction (the X direction and the Y direction shown in the figure are examples).

  In different axial directions between a plurality of sensing areas in such a single-layer sensor element, a plurality of electrode wirings not connected and a plurality of electrode wirings connected in close proximity are included. For example, the plurality of adjacent first electrodes 11 are non-continuous wiring in which the plurality of first electrodes are not connected to each other. On the other hand, a plurality of adjacent second electrodes 21 are continuous wirings connected by a second lead wire 22 between the plurality of second electrodes 21. A plurality of wirings are formed in the axial direction where the first electrode 11 is provided, and a plurality of first electrode wirings 13 connected to the outside are formed. In the axial direction where the second electrode 21 is provided, a plurality of wirings connected to the outside are formed by the second electrode wiring 23.

  The patterning method can be realized by an etching method in a semiconductor process. For example, a dry etching process or a wet etching process may be used.

  In the dry etching process, a plurality of sensings may be formed on the substrate surface by patterning the first transparent conductive material, for example, by applying etching pastes, laser engraving, or shutter mask deposition. An area and a plurality of signal wiring areas are formed.

  The dry etching method is divided into a physical etching method and a chemical etching method. As the physical etching method, a physical sputtering method may be considered. The principle is that air is dissociated into positively charged ions by glow discharge, ions are accelerated by a bias voltage, and ions are sputtered onto the surface of the object to be etched. Type. The dry etching process includes a step of performing a chemical reaction, a step of performing ion-assisted etching, a step of forming a protective layer so as to prevent etching of an area that should not be etched, and a step of eliminating residues. Including.

  In the wet etching method, for example, a sensing area and a signal wiring area are formed by a photolithography process that performs exposure, phenomenon, and etching. In the wet etching process, a portion of the first transparent conductive material that should not be etched (for example, a sensing area and a signal wiring area) is covered with a photoresist, and the other areas are etched with a predetermined chemical solution. The etching process was completed by eliminating the compound. Since the wet etching method is mainly performed by a chemical reaction between an etching solution and an object to be etched, the chemical solution can be appropriately selected and blended.

  The wet etching process includes a step of diffusing a chemical etching solution on the surface of the conductive material, a step of chemically reacting the chemical etching solution and the object to be etched, and a chemical etching of the reactant generated by the chemical reaction from the surface of the object to be etched. Diffusing into the solution and simultaneously being removed with the chemical etching solution.

  As shown in FIG. 3C, by performing the patterning process of step S205 and etching the conductive material 303, the first electrode 11, the second lead wire 22 positioned between the second electrodes, 1st electrode wiring 13 electrically connected to one electrode is formed. The cross-sectional view shown in FIG. 3C corresponds to the disconnection 3C indicated by the dotted line in FIG. 4A.

  Since the plurality of first electrodes and the plurality of second electrodes formed in the above-described steps simultaneously include sensor electrodes that are uniformly distributed on one plane, continuous electrode wiring (for example, second electrode) is provided in one axial direction. A sensing signal for one axial direction is generated by using a plurality of electrodes connected with each other. On the other hand, a plurality of sensor electrodes are also included in the other axial direction, but these electrodes are a plurality of first electrodes that are not connected to each other.

  In order to connect the discontinuous sensor electrodes, in step S207, a jump connection insulating layer is formed between the discontinuous electrode wirings by, for example, spray coating. For example, an oxide layer is sprayed between discontinuous electrode wirings. Further, as shown in FIG. 3D, a jump connection insulating layer 305 is formed between the first electrodes 11 to cover the second lead wire 22 connected to the other second axial electrode. The cross-sectional view shown in FIG. 3D corresponds to the disconnection 3D shown in FIG. 4B. FIG. 3D shows a state in which the jump connection insulating layer 305 is formed between the first electrodes 11.

  Subsequently, in step S209, a transparent conductive material (second transparent conductive material) is spray-coated on each jump connection insulating layer. The conductive material is preferably a material that can be cured by a photocuring method or a thermosetting method. As shown in FIGS. 3E and 4C, the first lead wire 12 is formed on the jump connection insulating layer 305. FIG. 3E corresponds to the disconnection 3E in FIG. 4C. As described above, as a transparent conductive material for forming the sensing area and the signal wiring area (that is, the first electrode, the second electrode, and their wiring), for example, indium tin oxide (ITO), Using materials such as nano silver, nano copper, conductive polymer, carbon nanotube, graphene, silver bromide (AgBr), indium gallium zinc oxide (IGZO) May be. In addition, the conductive polymer is a chemical derivative doped, such as polyaniline, polyaniline derivative, polythiophene, polythiophene derivative, and the like. It is not limited.

  A transparent conductive material (first transparent conductive material) applied to a substrate and forming a sensing area and a signal wiring area and a transparent conductive material (second transparent conductive material) for forming a jump connection conductive layer May be the same material or different materials. Since the second transparent conductive material functions as a small area jump connection conductive layer, the light transmittance may be 80% or more.

  In the spray coating process used in step S207 and step S209, the insulating layer and the conductive material having a high light transmittance are discontinuous by the spray coating method with an accuracy of 0.1 μm to 5 μm (droplet method). Spray coating is sequentially applied to the discontinuous electrode wiring (Y direction shown in FIG. 4A) between them. Subsequently, in step S211, the insulating layer and the conductive material having a high light transmittance are thermally cured, or cured by ultraviolet rays (UV), whereby discontinuous electrode wirings are formed at predetermined positions of the continuous electrode wirings. A jump connection conductive layer for jump connection is formed. As shown in FIG. 3E, the first lead wire 12 functioning as a jump connection conductive layer was formed. The first lead wire 12 connects two adjacent first electrodes 11.

  As described above, a base material having a polarization function, a plurality of first electrodes and second electrodes having different axial directions, a jump connection insulating layer and a first lead wire between adjacent first electrodes, Polarized light in which a touch sensor element is provided on the surface of the polarizing plate by a combination of elements such as a second lead wire between the two electrodes and a first electrode wiring connected to the sensing circuit and a second electrode wiring. Configure the device.

  Subsequently, in step S213, the polarizing device manufactured by the method for manufacturing the touch sensor element of the polarizing plate is combined with the display module to be a polarizing device having a touch function above the display module.

  The display module may meet, for example, a liquid crystal display (LED) or a light emitting diode display using an organic light emitting diode (OLED). The type of the liquid crystal display may be, for example, a TN type, an STN type, a TFT type, or an LTPS type. The type of the organic light emitting diode display may be, for example, a small molecule type, a polymer type, an active matrix, or a passive matrix type.

  In addition, the manufacturing method of the touch sensor element of the polarizing plate uses a conductive polymer material and a precision coating method, so that it is possible to realize a low temperature electrode jump connection, improve the accuracy and linearity of the touch sensor element, Thinning can be achieved. Moreover, in the manufacturing method of this invention, a low temperature process of 80 to 90 degreeC is used. The purpose of using the low temperature process is that the heat resistance temperature of a general polarizing plate is not high.

  4A to 4C are schematic views showing an example of a jump connection method in the polarizing device according to the present invention. FIG. 4A shows an aspect of a surface electrode generated by patterning in the method for manufacturing a touch sensor element of a polarizing plate according to the present invention.

Electrode wirings (here, a plurality of first electrodes 11 were formed in the Y direction) were respectively formed.

Is electrically connected. The plurality of non-continuous first electrodes 11 formed in the Y direction are formed by forming non-continuous electrodes so as to avoid electrical interference and short circuits with the plurality of second electrodes 21 formed on the same surface. It has become. The first electrode wiring 13 electrically connects the first electrode 11 to the sensing circuit 410.

  In order to be electrically connected to the external sensing circuit 410, the electrodes in the respective axial directions are connected to one side of the polarization device in a concentrated manner by electrode wiring. In this embodiment, since the wiring and each transparent electrode are simultaneously formed by one patterning, each material is preferably a transparent conductive material. Moreover, each material may be the same type of transparent conductive material, or may be a different type of transparent conductive material.

  Subsequently, as shown in FIG. 4B, an electrically insulating structure is formed between the discontinuous electrode wirings by spray coating. In FIG. 4B, the plurality of first electrodes 11 formed in one direction (for example, the Y direction) are discontinuous electrodes. A jump connection insulating layer 305 for jumping between the plurality of second electrodes 21 formed in the other direction (for example, the X direction) was formed between the adjacent first electrodes 11. Since the formation method can be understood with reference to FIGS. 2 and 3D, the description thereof is omitted. FIG. 3D shows a part of the disconnection 3D in FIG. 4B. Subsequently, as shown in FIG. 4C, the first lead wires 12 between the adjacent first electrodes 11 are formed in the jump connection insulating layer 305 by spray coating. Since the formation method can be understood with reference to FIGS. 2 and 3E, description thereof is omitted. FIG. 3E shows a part of the disconnection 3E in FIG. 4C. Since the first lead wire 12 and the second electrode 21 (X direction) below the first lead wire 12 are insulated from each other by the jump connection insulating layer 305, electrical interference can be prevented.
