 The present invention relates to a digital capacitive touch screen and a method of manufacturing the same. More particularly, the present invention relates to a digital capacitive touch screen and a manufacturing method thereof. The present invention relates to a digital capacitive touch screen and a method of manufacturing the same for facilitating signal control by flowing a current for sensing at the same level.

Recently, with the development and popularization of the GUI (Graphic User Interface) system, the use of a touch screen with a simple input is becoming common.

There are largely a touch screen, a resistive method, a capacitive method, an optical method, an ultrasonic method, an electromagnetic method, and a vector force method, and each method has advantages and disadvantages.

In general, the capacitive method is divided into analog (digital) and digital (digital) method.

In the analog method, the sensor electrode is a sheet-shaped electrode, which does not require a pattern in the sensing operation area, whereas the digital method requires a pattern of the sensor electrode in the sensing operation area.

In addition, both capacitive touch screens, whether analog or digital, basically have a protective layer of a specific dielectric constant to protect the sensor electrode between the sensor electrode and the finger.

1 is a plan view of a conventional digital capacitive touch screen, Figure 2a is a view showing the electrode pattern for the x-axis recognition in the conventional digital capacitive touch screen, Figure 2b is a y in the conventional digital capacitive touch screen It is a figure which shows the electrode pattern for -axis recognition.

Referring to this, the x-axis recognition sensor electrode 4 and the sensor-delivery lead electrode 44 shown in FIG. 2B are formed on the substrate 1, and the substrate 1 is disposed below the substrate 1. By providing the y-axis recognition sensor electrode 2 shown in 2a and the lead electrode 22 for signal transmission between the sensors, the digital capacitive touch screen A 'shown in FIG. 1 is formed.

3 is a cross-sectional view taken along line I-I of a conventional digital capacitive touch screen, and FIG. 4 is a cross-sectional view taken along line II-II of a conventional digital capacitive touch screen.

3 shows a cross-section parallel to the Y-axis recognition sensor electrode 4, so that the sensor electrodes on the substrate 1 are continuously connected, and the X-axis recognition sensor electrode 2 has a cross-sectional length direction. Since it is perpendicular to, the electrode is discontinuously displayed.

As shown in FIG. 4, it can be seen that the x-axis and y-axis sensor electrodes 4 and 2 are discontinuously displayed on the upper and lower sides of the substrate 1.

However, the conventional digital capacitive touch screen A 'has some problems.

That is, the x-axis and y-axis sensor electrodes 4 and 2 are disposed on the upper and lower sides of the substrate 1, and a protective layer 3 is provided to protect the electrodes. There is a problem of increasing and the number of layers increases.

In addition, the parasitic capacitance between the finger and the x-axis and y-axis sensor electrodes 4 and 2 decreases in inverse proportion to the distance between the two objects.

As shown in FIG. 4, since the x-axis and y-axis sensor electrodes 4, 2 are provided with the substrate 1 interposed therebetween, the x-axis and y-axis sensor electrodes 4, 2 and the finger. The parasitic dose values between the two must be different.

That is, in the case of the capacitive method, since the value of the flowing current is very fine, the amount of leakage current is different according to the thickness of the substrate, and there is a disadvantage in that the difference in the change in the measured current is large when measuring the amount of current for each line.

In addition, since there are x-axis and y-axis sensor electrodes 4 and 2 around the substrate 1, there are also two FPC bonding portions for signal application, which has a disadvantage of requiring two or more operations.

That is, as in FIGS. 2A and 2B, since the FPC bonding unit 6 is separately, there is a problem that the work time is doubled.

In addition, the arrangement of the electrodes 4 and 2 for the x- and y-axis sensors is arranged with the substrate 1 interposed therebetween, resulting in a difference in parasitic capacitance, which affects the amount of leakage current.

At this time, the amount of leakage current flowing is very fine and amplified by the amplifying stage of the control circuit, and it is possible to detect changes in the microcurrent only through amplification of a very large value. In this process, even a small amount of leakage current shows a big difference in the amplification process. This is because the two x-axis and y-axis sensor electrodes 4 and 2 have different amplification characteristics. The magnitude of leakage current change can be generalized.

That is, there is a problem that two sets of amplification circuits and additional circuits such as separate offset control and current amount measurement are required for each of the x- and y-axis sensor electrodes 4 and 2.

In addition, in the conventional digital capacitance method having an electrode structure above and below the substrate, a separate noise removing shielding electrode is not used.

Therefore, the amplification of the microcurrent due to the variation of the capacitance leads to the accompanying amplification of the ambient noise. Even if precise filtering is performed, the accompanying amplification of the noise distributed in the filter band cannot be avoided.

Due to the characteristics of the touch screen bonded on the LCD including various frequency noises, the structural member of the shielding electrode is relatively vulnerable to noise.

The present invention has been made to solve the above-mentioned problems of the prior art, and the thickness of the x-axis and y-axis position sensing sensor electrodes on the same plane can be made thinner, and the x-axis and By minimizing the distance between the sensor electrodes for detecting the y-axis position, the difference in the parasitic capacitance between the finger and the sensor electrode can be minimized, and the difference in the leakage current can be minimized by minimizing the difference in the parasitic capacitance. As a result, the amplification circuit, offset control, and additional circuits such as current measurement can be omitted, and the configuration of the control circuit can be simplified, and the digital capacitive touch screen with excellent noise shielding performance can improve reliability and its manufacture. The purpose is to provide a method.
