Description

Gender for mobile devices with non-contact touch pens {MOBILE PHONE GENDER COMBINED CONTACTLESS TYPE TOUCH PEN}

The present invention relates to a gender for a portable terminal in which a touch pen is coupled, and more particularly, a gender (Z) value of impedance (including the capacitance of a capacitor generated when a touch panel is touched and a human resistance) to be applied externally. It can be operated by itself, and unlike the capacitive touch method, it integrates the non-contact touch pen which enables the touch function to be generated by generating its own Z value even when wearing a glove or an outer skin covering the hand. It relates to a gender for a mobile terminal.

In general, a gender terminal for a portable terminal is a connector having a pin structure, and functions as a connection medium that allows a charger to be used or a USB connection, and is mainly used for charging and data transmission of a portable terminal. Accessories for the terminal.

On the other hand, in recent years, with the development of semiconductor technology and electronic technology, portable terminals having a touch panel adopting a touch screen method have been introduced, and the spread of the touch panel has been expanded. Touching the transparent surface installed in the finger or a pen (pen) to operate the system of the mobile terminal, the touch pen is used together for more accurate touch input and ease of use.

In the touch panel, a resistive film method, a capacitive coupling method, an infrared method, an ultrasonic method, and the like are used. In recent years, a capacitive coupling type touch panel is most commonly used. The person touches the touch screen to form a capacitance, flows a weak current through the capacitor, detects the change, and calculates a touch position to perform an operation process.

The capacitive coupling method is similar to the resistive film in that there are horizontal and vertical electrodes (sensor wires), but instead of conducting the touched place like the resistive film, it senses the change in capacitance formed between the electrodes. To recognize the touch position.

In other words, since the human body has a lot of water, it has conductivity, and the capacitance between the finger and the electrode increases when the human body approaches the electrode which is horizontal and vertical as in the example of FIG. 1. It recognizes whether the intersection of lines is touched by recognizing the large capacitance between lines, and there is no risk of deforming the electrode like the resistive film, and it is also resistant to scratches because it can cover the surface of the touch panel with glass. It has advantages of durability and environmental resistance.

However, when the insulator in which the change in capacitance hardly occurs is approached, the capacitance is not detected and thus the touch cannot be recognized, and as shown in the example of FIG. 2, the touch cannot be detected at all when the user wears gloves. It has the disadvantage of not being able to.

As a result, there is a problem in that the capacitive coupling touch panel cannot be used in the winter season or in the cold season (North Pole, Antarctica).

3 is a diagram illustrating a one-dimensional operation principle of a capacitive coupling type touch panel, and FIG. 4 is a diagram illustrating an equivalent circuit during one-dimensional touch.

As shown in Fig. 3, when A and B function as a touch panel (resistance value is R), the alternating current in phase and coincidence is exchanged through the current detection resistor r connected to both ends thereof. When applied, the steady current does not flow in the coin state.

In addition, as shown in FIG. 4, when an arbitrary point C is touched by a finger between the AB functions as a touch panel, a capacitor is formed between the surface layer of the AB and a human and a weak current flows at both ends. If i1 and i2 are set and the resistance values at the C point positions are R1 and R2, respectively, the currents i1 and i2 flowing from both ends can be calculated by the following equation.

i1 = e (r + R2) / R (Z + r) + R1R2 + 2Zr + r2,

i2 = e (r + R1) / R (Z + r) + R1R2 + 2Zr + r2

Here, Z is an impedance including the capacitance of a capacitor and a human resistance generated when a human touches a touch part with a finger.

From the above equation, the ratio between the total resistance value (R = R1 + R2) and the resistance value R1 up to point C is obtained.

R1 / R = (i2 / i1 + i2) (1+ (2r / r))-r / R

as mentioned above,

In the relationship i1 = e (r + R2) / R (Z + r) + R1R2 + 2Zr + r2, i2 = e (r + R1) / R (Z + r) + R1R2 + 2Zr + r2, Once you find it,

Z = e (r + R2) + Rr (R1R2-i1 + 2Zr + r2) / R (i1-R1R2-2Zr-r2).

In other words, the conventional operation method of the capacitive touch pen is a medium for transmitting Z, which has to be applied from the outside by a human having a Z value, and has a conductive touch pen. There was a problem of becoming impossible.

Therefore, in the present invention, a non-contact capacitive touch pen which allows the gender itself to operate by holding the value of Z (impedance including the capacitance of the capacitor and the human resistance generated when the touch panel is touched) to be applied from the outside. It will be described below and provide a gender for a portable terminal combined with one.

The present invention has been made in view of the above-described problems, and is configured by integrally combining a touch pen having a nib made of a conductive material and a gender body of a plastic non-conductor, but for applying a Z value to be applied from the outside to the touch pen side. Gender itself holds the value of Z (capacity of capacitor generated when touching the touch panel and impedance including human resistance) which should be applied from outside by connecting the circuit inside the gender body so that the touch function can operate itself. Unlike other capacitive touch methods, this product uses a gender-free gender-based gender-integrated, non-contact touch pen integrated with a non-contact touch pen that enables a smooth touch function by generating its own Z value even when wearing a glove or an outer skin covering the hand. The purpose is to provide.

The present invention is to extend the scope of application, such as the use of capacitive coupling touch panel in the winter or cold season many regions (North Pole, Antarctica), non-contact touch pen to further increase the ease of use It is to provide a gender for the combined mobile terminal.

An object of the present invention is to provide a gender for a portable terminal in which a non-contact capacitive touch pen and a non-contact touch pen are integrally coupled to an antenna on a gender body.

The present invention allows a non-contact capacitive touch pen to be used, but by constructing a structure capable of separating and coupling the nib of the touch pen, a non-contact touch pen combined with a non-contact touch pen can be used as needed. To provide a gender for the terminal.

The present invention for achieving the above object, in the gender for a portable terminal equipped with a PCB assembly equipped with a first connector for connecting to the portable terminal side, and a second connector for connecting to the charging cable or data communication cable. In

A Z value applying circuit having an impedance (Z) value including a capacitance of a capacitor and a human resistance generated when the touch panel is touched on the PCB assembly is mounted on the PCB assembly and is in contact with the touch panel while being coupled to the PCB assembly. By connecting the conductive pen tip of the touch pen so that the gender itself holds the Z value to be applied from the outside;

When the conductive pen tip is in contact with the touch panel, it generates a Z value by itself so that the touch recognition by the self operation is configured.

Preferably, the Z value applying circuit may be any one selected from an RL series circuit, a circuit in which L is serially coupled to an RC parallel circuit, a circuit in which C is parallel coupled to an RL series, a circuit in which R is coupled in parallel to an LC series, and an RLC series circuit. It is characterized by.

Unlike the conventional capacitive touch method, the touch function is recognized by generating a Z value when a touch pen is touched to the touch panel by the Z value applying circuit even if a glove or an outer skin surrounding the hand is worn. Because it operates itself, it is possible to extend the scope of application such as capacitive touch panel in the winter season or cold season (North Pole, Antarctica), and to improve the usability of touch type mobile terminal. It has a useful effect.
