In the conductive liquid crystal protective film part 10 of the present invention, the PET film 11, the thermosetting resin film 12, and the conductor film 13 are sequentially stacked from top to bottom.

The conductive liquid crystal protective film unit 10 is present on the liquid crystal contact surface of the mobile phone case 20 so that the touch signal can be directly applied to the touch screen panel 1 of the mobile phone through the conductive liquid crystal protective film unit 10. do. At this time, the conductive liquid crystal protective film unit 10 is configured to operate both capacitive and pressure-sensitive.

When the conductor film 13 is in contact with the capacitive touch screen panel, static electricity is generated at the point of contact as with the human body to enable information input.

Therefore, the conductor film 13 is formed of a metal material having a dielectric constant value that can be detected as an input signal by changing the capacitance value of the capacitive touch screen panel at the point of contact. .

For example, at least one conductive material selected from the group consisting of copper (Cu), nickel (Ni), gold (Au), and carbon may be used as an optimal material for forming the conductor film 13. In order to add bactericidality and conductivity to the surface of the conductive material, an electroless plating layer using silver (Ag) may be further used.

The conductor film 13 is formed to have a thickness of several μm on one side of the thin film member through a deposition process such as chemical vapor deposition (CVD) or physical vapor deposition (PVD). The flexibility of the thin film member can be maintained.

On the other hand, the present invention was configured to be automatically restored after the touch the rounded conductive LCD protective film portion round.

That is, when the LCD protective film portion is in a horizontal state, when the restoring force is reduced, the multi-switching operation may occur by sticking to the liquid crystal. In the present invention, the entire LCD protective film portion is formed to be round so as to naturally return to the upper direction after the touch. will be.

Therefore, since the present invention can be easily restored after the touch, it is possible to block the multi-switching phenomenon even when using for a long time, so only the signal of the part touched by the user can be used, thereby enabling more accurate mobile phone use.

First of all, the present invention measures the output impedance of the touch screen panel 1 of a device such as a smart phone or a navigation system, and finds and manufactures a film having an optimized tensile impedance suitable for it.

Hereinafter, the technical details of the impedance will be described.

Audio devices have an impedance value for each device to be set, and the matching of the impedance values creates an optimal balance. Therefore, it is necessary to understand the characteristics of each device to be set and impedance matching, and if the impedance matching is not good, audio often affects amplification and distortion (distortion), so that proper reproduction is not performed. Ideal impedance matching is such that the input impedance is as high as possible and the output impedance has at least low impedance resistance.

In the case of amplifier refiners and speakers, the most important combination is the impedance matching. If you look at the specifications of the amplifier and speaker, the impedance must be marked. For the amplifier refiner, the output impedance must be checked, and for the speaker, the input impedance must be checked and the same impedance matching product must be selected. If the amplifier's impedance is 8 ohms and the speaker's impedance is 4 ohms, then the speaker's permissible input is doubled, which can cause distortion in the actual sound or damage the speakers.

For preamplifiers and power amplifiers, the output impedance of the preamplifier and the power amplifier input impedance must be checked. A typical preamplifier's output impedance is 47 ohms (100 ohms in balance), while the power amplifier's allowable input impedance is 10,000 to 22,000 ohms (44,000 to 50,000 ohms in balance). In other words, the input impedance should be larger and allowable than the output impedance.

The importance of impedance matching also applies to headphones and microphones, so for headphone amplifiers, products with the widest possible impedance are preferred. In addition, audio devices with matching devices and equipment such as tube amplifiers and phono amplifiers have inherent impedance.

The present invention was applied to this impedance to the smart phone and smart phone screen protectors other than the combination of the amplifier and the speaker of the input impedance of the smart phone LCD protective film 10 in preparation for the current output impedance of the smart phone is a 100 ohm ^2- The inherent output impedance of each smartphone A is measured at a size of 10 ⁵ ohms, and this is a top priority of the present invention to optimize the input impedance of the conductor film 13 of the LCD protective film.

Considering the matching of the input impedance of the conductor film 13 with the output impedance of the touch screen panel 1 as well as the capacitive touch on the existing capacitive touch screen, it operates in a reduced pressure method when the touch is not performed by the capacitive touch screen. It is a mixed structure of two methods that enables the touch to the non-conductor, which is the maximum advantage of the conventional method, as well as the multi-touch which is the maximum advantage of the existing electrostatic method.

In other words, the film of the present invention stimulates the output impedance of the smartphone by touching the LCD protective film with a hand or other non-conductor, and transmits the electric signal to the main body of the smartphone to operate the touch. It can be referred to as a mixture of the method and the impedance method (poster).

Film made with the touch implementation according to the invention are conventional silver nano wire, carbon nano-tubes, methyl mesh, child thio (ITO), the surface resistance is very low film (10 ohms), such as antistatic (10 ⁵ - 10 ¹¹⁾ It is characterized by using a value (10-10 ⁵ ), rather than a film having a very high surface resistance.

Looking at the manufacturing method of the present invention below.

Preparing a PET film 11;

Applying a liquid thermosetting resin on top of the PET film 11;

Passing the PET film 11 coated with the liquid thermosetting resin through a dryer to solidify the liquid thermosetting resin so that the thermosetting resin film is laminated on the PET film 11;

Stacking a conductor film (13) on top of the thermosetting resin film (12);

The laminated film is cured while being rounded at a predetermined angle.

In the above, the thickness ratio of the PET film 11, the thermosetting resin film 12 and the conductor film 13 is preferably arranged 1: 4-5: 1, wherein the thickness ratio of the thermosetting resin 12 is PET film If less than 4 times compared to the 11 and the conductor film 13, the restoring force is not provided after touching the touch screen panel 1, the thickness ratio of the thermosetting resin 12 is PET film 11 and the conductor film 13 In case of exceeding 5 times, the touch feeling is inferior.

Accordingly, the present invention limited the thickness ratio of the thermosetting resin 12 to 4-5 times based on the thicknesses of the PET film 11 and the conductor film 13 to maintain the touch feeling and at the same time have a restoring force.

Designing to have a restoring force by the thermosetting resin film as described above provides a convenience that does not need to be separately mounted to the conductor film.

In other words, if the thermosetting resin film is not used, the LCD protective film part cannot be restored after touching, so that a spacer must be formed on the conductor film to avoid multiple contact, and the conventional film part is pressed when one side is not installed. There were inconveniences in that unwanted input was made by multiple inputs of the liquid crystal of the mobile phone due to multiple touches of different parts.

That is, a spacer having a plurality of protrusion structures originally existed between the conductive LCD protective film portion and the touch screen panel of the mobile phone, and the protrusion structure is formed on the bottom surface of the conductive liquid crystal protective film portion. Therefore, it was a structure in which multiple touches were prevented when the conductive LCD protective film part was touched.

Accordingly, in the conventional film part, the conductor film 13 has to be essentially equipped with a spacer, but in the present invention, since the thermosetting resin film 12 is applied, the thermosetting resin film is the liquid crystal protective film part 10. It plays an elastic role of lifting the whole, so it is possible to maximize the convenience of use by automatically returning to the original position after touching without installing a spacer.

Meanwhile, after the LCD protective film is photographed by the camera 400, the rounded state is determined, and if the rounded state is not within the reference range, the control unit 500 alerts an error condition through the error signal automatic output unit 1000 within a short time. Induce error resolution.

The alarm signal automatic output unit 1000 includes a circuit power supply 1101, an alarm signal output unit 1102, an oscillation transformer 1103, a relay operation switching unit 1108, a relay switch 1107, and the like. And a first circuit connection switch sw1, an alarm signal output power switch sw2, and a power holding switch 1118.

The power supply unit 1101 applies a power signal by its own power supply.

The alarm signal output unit 1102 switches the power supply circuit when a control signal is output from the controller.

When the power supply is turned on, the oscillation transformer 1103 outputs an AC current in which electricity is supplied and boosted.

The relay operation switching unit 1108 is connected to an output terminal of the oscillation transformer 1103 and turned on by an electrical supply.

The relay switch 1107 is installed at the output terminal of the relay operation switching unit 1108 and generates a magnetic force.

The first circuit connection switch sw1 performs a function of energizing a circuit while the iron piece is pulled by the relay switch 1107.

The alarm signal output power switch sw2 serves to guide the alarm signal to be displayed by supplying power to the alarm signal output control unit 1140 while the iron piece is pulled by the relay switch 1107.

The power maintaining switching unit 1118 is connected to the first circuit connection switch and the base end, the emitter end and the collector end are connected to the oscillating transformer 1103 and the relay operation switching unit 1108, the relay operation switching unit The operation of 1108 causes the iron piece to be pulled to form a closed circuit, switching on, thereby stopping the relay switch 1107 from operating. At this time, when forcibly turning off the first circuit connection switch sw1 and the alarm signal output power switch sw2, the closed circuit is broken and the switching is turned off, and the relay operation switching unit 1108 is turned on so that the relay switch is turned on. The first circuit connection switch sw1 and the alarm signal output power switch sw2 are turned on to induce the alarm signal to be continuously output.

In addition, the present invention, the iron piece 1113 for circuit operation, the iron piece 1132 for connecting the alarm signal operation control unit, the first magnetic holding means 1133, the second magnetic holding means 1134, and auxiliary magnetic holding It further comprises a means 1133a, a gap agent 1134a, and a manual operation switch 1135.

The iron piece 1131 for circuit operation is contacted to the first circuit connection switch sw1 to turn on the power holding switch unit 1118.

The alarm signal output controller power connection iron piece 1132 is designed to operate in conjunction with the circuit operation iron piece 1131, and when the circuit operation iron piece 1131 is turned on, the power is connected to the alarm signal output control unit 1140. Induce the alarm to activate.

The first self-holding means 1133 is installed at the lower end of the iron plate 1131 for circuit operation, and has a rod magnet shape having a lower end of the S pole, so that the relay switch 1107 is inoperative when the relay switch 1107 is not operated under the influence of the S pole. (sw1) and the circuit-working iron piece 1131 are induced to remain off at all times.

The second magnetic retaining means 1134 is installed on the upper part of the first circuit connection switch sw1 and has a rod magnet shape with an upper end of S pole. When the relay switch 1107 is inoperative, the first magnetic having a lower end is S pole. The holding means 1133 are pushed together to push up the circuit actuating iron piece 1131 to maintain the electrical off state, and when the relay switch 1107 is operated, the circuit actuating iron piece 1131 is pulled to form an upper part of the body. The S pole and the N pole constituting the upper part of the body of the first self-holding means 1133 are located adjacent to each other, and at the same time, the N pole and the lower part of the body of the first self-holding means 1133 are constituted. If the S pole is located in close proximity and magnetically coupled to the first magnetic holding means 1133 and at the same time the first circuit connection switch sw1 is switched, the attachment of the iron piece 1131 for circuit operation even if the operation of the relay switch is stopped. Status is total It is then continued to maintain the on state of the power switching unit 1118 for. At this time, when the iron piece for circuit operation is operated by the operation of the relay switch 1107, the iron piece for connecting the alarm signal output control unit is automatically operated so that the alarm signal is output to the outside.

The auxiliary self-maintaining means 1133a is installed at the lower end of the circuit actuated steel plate 1131 in a state spaced apart from the first self-maintaining means 1133 by a predetermined distance, and the lower end is formed of a bar magnet having an S pole and an upper end thereof is S. When the relay switch 1107 is deactivated while being pushed by the second magnetic holding means that is poled, the iron piece 1131 for circuit operation is lifted from the first circuit connection switch sw1 to maintain the circuit disconnection state, and the relay switch 1107 is operated. The iron piece 1131 for the trial circuit operation is lowered to maintain the on state of the first circuit connection switch sw1.

In particular, the auxiliary self-holding means 1133a affects the second self-holding means 1134 even when the first self-holding means 1133 is lost, so that the relay circuit 1107 is turned off when the relay switch 1107 is not operated. And magnetically coupled to the second self-holding means when the relay switch 1107 is operated to maintain the on state of the first circuit connection switch sw1.

The spacer 1134a is installed around the N pole of the second self-holding means 1134, and the second self-holding means and the first self-holding means are not directly coupled to each other when they are magnetically coupled to each other. It is induced to be coupled to maintain the main body, and when the first self-maintaining means and the second self-maintaining means are disengaged so that they can be separated from each other more naturally. If the spacer does not exist, the body of the first self-maintaining means and the body of the second self-maintaining means directly adhere to each other. Accordingly, in the present invention, the spacer is further installed so that the first magnetic holding means and the second magnetic holding means can be easily separated.

Further, the reason why the spacer is installed only around the N pole of the second self-holding means is that the first self-holding means and the second self-holding means should be separated when the relay switch is inoperative. Since the pole and the S pole of the second self-holding means face each other, the separation state can be easily maintained. If the spacer is wrapped up to the S pole of the second self-holding means, when the relay is inoperative, the S pole of the first self-holding means and the second self-holding means is pushed down by the interference of the spacer, so that the space is maintained. May become unstable.

Accordingly, in the present invention, the spacer is provided only on the north pole of the second self-holding means so that the first self-holding means and the second self-holding means can be easily separated. Due to the arrangement, the magnetic coupling state can be easily maintained. In fact, when the first self-holding means and the second self-holding means are coupled to each other, the north pole of the first self-holding means and the S pole of the second self-holding means are located in close proximity, and thus are magnetically strong. Even if the relay switch is turned off, the falling state of the circuit actuated iron piece 1131 is continued, so that the on state of the first circuit connection switch sw1 can be maintained.

The manual operation switch 1135 is coupled to the iron for circuit operation and the iron signal for connecting the alarm signal output control unit, and when the user operates to stop the alarm signal operation in the off state of the alarm signal output unit, the iron and alarm for circuit operation By turning off the iron for connecting the signal output control unit and stopping the operation of the alarm signal display unit, the alarm signal is no longer output.

Looking at the operation of the automatic alarm signal output unit 1000 as follows.

First, when the alarm signal output unit 1102 is turned on, DC power is connected to supply power to the oscillation transformer, and a high voltage is applied to the secondary side of the oscillation transformer.

The power supplied to the secondary side becomes a half-wave DC power supply through the rectifying diode, and this half-wave DC power supply becomes a more stable DC power supply due to the charge / discharge action of the capacitor.

This DC power is applied to the anode end of the thyristor via the coil of the relay switch 1107, while the DC power is charged to the capacitor through the resistor. The increased voltage triggers the relay operation switching unit 1108 while passing through the diaak so that the anode and cathode terminals are switched to perform the operation of the relay switch. Accordingly, the operation of the relay switch 1107 causes the first switch to operate. When the circuit connection switch sw1 and the alarm signal output power switch sw2 are turned on, power is applied to the alarm signal output control unit 1140 to display an alarm signal.

When the first circuit connection switch sw1 operates, the base end of the power holding switch 1118 is activated while inducing a closed circuit to the emitter end and the collector end of the power holding switch 1118 to supply power to the transformer. Turned off.

That is, a voltage between the resistor 1109 and the capacitor 1110 flows through the diode 1120 between the emitter terminal and the collector terminal of the power holding switch 1118 and is bypassed. When the voltage of the voltage is lowered and the voltage between the resistor and the capacitor is lowered, the trigger signal directed to the relay operation switching unit 1108 is stopped so that the current flows through the relay switch 1107 while the anode end and the casing end are turned off. It stops supplying power for switching.

On the other hand, if the operator turns off the first circuit connection switch and the alarm signal output power switch while the alarm signal is being output, there is no current flow in the closed circuit, and accordingly, the bias voltage flowing between the emitter end and the base end of the power maintenance switching part is accordingly. This disappears and the power holding switch 1118 is turned off.

As the power maintenance switching unit 1118 is turned off, the bypass voltage between the resistor and the capacitor through the diode 1120 disappears, and the voltage is charged in the capacitor 1110.

This charged voltage causes the break-over phenomenon of the diac 1111 and outputs a trigger signal from the diac to the auxiliary switch operation switching unit 1108 to maintain the closed circuit while moving the iron piece, and at the same time the alarm signal controller 1140. By returning the power output to the) it is possible to continue to operate the alarm signal display unit 1150.

That is, according to the present invention, if the alarm factor is not solved, the alarm sound is continuously output, thereby inducing to solve the alarm factor.
