Description

TOUCH SCREEN PANEL AND METHOD FOR MANUFACTURING THE PANEL}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a touch screen panel, and in particular, in response to an increase in the number of channels due to an increase in size of a touch screen panel, transparent electrode rows divided into a plurality of groups are divided into a primary electrode group and an auxiliary electrode group. Each electrode of the auxiliary electrode group is disposed between the base electrodes of the base electrode group at a predetermined interval or more so as not to cause a touch recognition error, and then, to each electrode composed of a plurality of split electrodes in the auxiliary electrode group. The present invention relates to a touch screen panel and a method of manufacturing the same for reducing the total number of channels by connecting the split electrodes in the same direction to the same channel.

In general, a touch screen device refers to an input device for detecting a user's touch position on a display screen and performing general control of an electronic device including control of a display screen using information regarding the detected touch position as input information.

The touch screen device is classified into a discrete position detection method and a continuous position detection method according to an implementation method.

Discrete location detection, also called matrix method, divides the two-dimensional plane on the touch screen panel into a plurality of compartments, and obtains information about the contact position of the user by detecting whether there is contact or non-contact for each compartment. .

M signal lines 11 and N signal lines 12 for sensing the vertical position are provided.

The discrete position detection method is easy to implement because it detects the contact with each compartment 15 to obtain the contact position without complicated algorithms for calculating the contact position, while the size of the compartment 15 and the signal lines 11 and 12 are easy to implement. The resolution of the contact position recognition is determined according to the patterning precision of), and since the number M of distinguishable horizontal positions and the number N of vertical positions are limited by the number of sensing channels of the touch sensing circuit, there is a limit that it is difficult to precisely recognize the position.

Another method for solving the above-described problem in the discrete position sensing method is a continuous position sensing method. Continuous location detecting is a method of recognizing a contact location on a two-dimensional plane as a continuous value, without dividing the touch detection area into a limited number of sections. The continuous position sensing touch screen device calculates horizontal and vertical coordinates continuously from values measured through a limited number of electrodes. Since the continuous position sensing method recognizes the contact position as a continuous coordinate value, there is an advantage of high accuracy in position recognition, and thus it is currently employed in many touch screen panels.

On the rear surface of the window 120, right-angled triangular transparent electrodes 111 and 112 formed in a horizontal direction are paired right and left so as to be repeatedly arranged at a plurality of positions in the vertical direction. The pair of transparent electrodes 111 and 112 are disposed in a shape in which two hypotenuses face each other, and the widest end side thereof is connected to each sensing channel of the touch sensing circuit unit 140 via a wiring pattern 130. It is.

Next, referring to FIG. 3, the transparent film 115 having the transparent electrodes 111 and 112 and the wiring pattern 130 formed thereon is laminated on the rear surface of the window 120. The touch sensing circuit unit 140 electrically connected to each of the transparent electrodes 111 and 112 through the wiring pattern 130 may change capacitance caused by a user's contact applied to the transparent unit 124 of the window 120. Detect.

As shown in FIG. 4, the above capacitance change is a part of the user's human body, for example, when the fingertip contacts a specific location on the transparent part 124, the contact surface of the transparent electrodes 111 and 112 at that location with the human body. Is modeled as a capacitor having two electrode plates and a dielectric material of the window 120 and the transparent substrate 115, a capacitance Ct formed in the thickness direction of the window 120, and a human body capacitance connected in series to the ground. It can be represented by Cb.

The touch sensing circuit unit 140 detects an electrical change caused by the capacitance, and the coordinate calculating unit 150 is based on the data on the capacitance change obtained by the touch sensing circuit unit 140 in the horizontal direction and the vertical direction of the contact position. Calculate the aromatic component.

In the following description of the present invention, if it is determined that a detailed description of a known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intentions or customs of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

5 illustrates an electrode structure of a touch screen panel implemented to reduce the number of channels in a large touch screen panel according to an embodiment of the present invention.

Hereinafter, an operation of the touch screen panel of the present invention will be described in detail with reference to FIG. 5.

First, in the present invention, the electrodes constituting the touch screen panel are divided into a plurality of electrode groups, and the electrodes divided into different groups are spaced apart at predetermined intervals so that a touch recognition error does not occur.

That is, as shown in FIG. 5, the electrodes constituting the touch screen panel may be divided into, for example, three electrode groups 500, 510, and 520, and the electrodes included in each group may be divided into one or more divisions. It may be made of an electrode.

The electrodes included in the first group 500 may be set to, for example, a basic electrode group to which a sensing channel is connected to each divided electrode of each electrode. Each electrode of the first group 500 may be disposed to be adjacent to an electrode included in the second group 510, and may be disposed to be adjacent to an electrode included in the third group 520.

In this case, different sensing channels are connected to the split electrodes constituting the electrodes of the first group 500, and the split electrodes constituting the electrodes included in the second group 510 and the third group 520 are each connected to the split electrodes. The division electrodes of each row included in the same group and located in the same direction are integrally connected to one sensing channel.

That is, in each row of electrodes included in the second group 510, the split electrodes of each row positioned on the left side of the touch screen panel are connected to a sensing channel of reference number 550 which is the same sensing channel. The split electrodes of each row located in the right direction on the panel are connected to the sensing channel of the same sensing channel 552.

In addition, in each row of electrodes included in the third group 520, the split electrodes of each row positioned on the left side of the touch screen panel are connected to a sensing channel of reference numeral 560, which is the same sensing channel, and is connected to the touch screen. The split electrodes of each row located on the right side of the panel are connected to the sensing channel of the same sensing channel 562. In this case, the electrodes included in the second group 510 and the third group 520 may be, for example, an auxiliary electrode group in which the divided electrodes of each row in the same direction among the divided electrodes constituting each electrode are connected to the same sensing channel. Can be set.

As described above, the sensing channel connection method is set differently for the electrodes in each group with respect to the first group 500 as the primary electrode group, the second group 510 as the auxiliary electrode group, and the third group 520. The number of sensing channels required for driving the screen panel can be reduced.

For example, in the case of the first group 500, the split electrodes included in the electrodes of each row are connected to different channels, respectively, while the second group 510 and the third group 520, that is, the auxiliary electrode group In this case, the divided electrodes included in the electrodes of each row are connected to one same channel by being connected to the divided electrodes included in the other group in the same group at the corresponding position, so that four channels are originally required, but only one channel is connected. It becomes possible.

Accordingly, no matter how many the rows of the electrodes included in the second group 510 or the third group 520 are, the left and right channels of the second group 510 and the left and right directions of the third group are included. Only four channels can be connected to each of the divided electrodes in each row, thereby significantly reducing the number of sensing channels.

That is, a total of 16 rows exist in the electrodes of the touch screen panel illustrated in FIG. 5, and an electrode of 8 rows having two split electrodes included in the first group 500 consumes 16 sensing channels in total. The electrodes included in the second group 510 and the third group 520 need only 20 channels in total by consuming 4 channels in total. This number of channels is a result of drastically reducing the number of 32 channels required when connecting different sensing channels to each of the divided electrodes without dividing the conventional electrodes into groups.

Meanwhile, in the touch position recognition in the touch screen panel including a plurality of electrodes having asymmetric split electrodes as described above, a part of the human body such as a finger touches as disclosed in the application number 10-2007-0114804 filed by the present applicant. In this case, since the touch position is determined according to the area ratio on the touched split electrodes, there is no problem in determining the x-axis coordinates of the human body even when the number of channels such as the sensing channel is reduced as in the present invention.

However, in determining the y-axis coordinates touched on the touch screen panel, when the divided electrodes of the electrode rows in the second group 510 or the third group 520 connected to the same sensing channel are positioned too close to each other, the y-axis A recognition error may occur when determining coordinates.

In order to prevent the y-axis coordinate recognition error, the distance between the split electrodes connected to the same sensing channel is arranged to be spaced apart by a predetermined distance where no recognition error occurs, or the number of auxiliary electrode groups is the fourth group and the fifth group. For example, the interval between the split electrodes connected to the same channel in the auxiliary electrode group may be spaced apart by a predetermined distance without a recognition error. In this case, the number of the auxiliary electrode groups as described above may be determined according to the size of the touch screen panel and the height of each electrode row.

6 illustrates an electrode structure of a touch screen panel according to another embodiment of the present invention.

In this case, as described above, each electrode on the touch screen panel of the present invention may include two or more divided electrodes, and FIG. 6 illustrates that each electrode includes three divided electrodes.

As described above, when the electrodes of each row have three split electrodes, different sensing channels are connected to the split electrodes in the rows of the first group 600 which are the basic electrode groups.

In addition, in each row of electrodes included in the second group 610 which is the auxiliary electrode group, the split electrodes of each row positioned on the left side of the touch screen panel are connected to the sensing channel of the same sensing channel 650. The division electrodes of each row positioned in the right direction on the touch screen panel are connected to the sensing channel of the same sensing channel 652. The split electrode located at the center of the rest is separately connected to the other sensing channel 654.

In addition, in each row of electrodes included in the third group 620 which is the auxiliary electrode group, the split electrodes of each row positioned on the left side of the touch screen panel are connected to the sensing channel of the same sensing channel 660. The division electrodes of each row positioned in the right direction on the touch screen panel are connected to the sensing channel of the same sensing channel 662. The split electrode located at the center of the rest is separately connected to the other sensing channel 664.

In addition, in each row of electrodes included in the fourth group 630, which is an auxiliary electrode group, the split electrodes of each row positioned on the left side of the touch screen panel are connected to a sensing channel of reference numeral 670, which is the same sensing channel. The division electrodes of each row positioned in the right direction on the touch screen panel are connected to the sensing channel of the same sensing channel 672. The split electrode located at the center of the rest is separately connected to the other sensing channel 674.

Accordingly, in addition to the sensing channel required for the first group 600, the second group 610, the auxiliary electrode group, and the third group 620, the fourth group 630, and the channel required for the n-th group The number S may be calculated as in Equation 1 below.

Figure 112012024538447-pat00001

N: number of groups of auxiliary electrode groups other than the first group

M: the number of split electrodes included in the electrodes of each row in the auxiliary electrode group

That is, for example, as shown in FIG. 6, since the number N of auxiliary electrode groups other than the first group is three, and the number M of split electrodes included in the electrodes of each row is three, the auxiliary electrode The number S of channels required for the electrodes of the group may be calculated as 3 × 3 = 9, and it can be seen that a total of nine channels are consumed.

As described above, in the manufacture of the touch screen panel, the transparent electrode rows divided into a plurality of groups are divided into a primary electrode group and an auxiliary electrode group in response to an increase in the number of channels due to the enlargement of the touch screen panel. Each electrode of the electrode group is arranged between the base electrodes of the base electrode group at a predetermined interval or more so as not to cause a touch recognition error, and then the same direction with respect to each electrode composed of a plurality of split electrodes in the auxiliary electrode group. The number of channels can be reduced by connecting the split electrodes in the same channel.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should not be limited by the described embodiments but should be defined by the appended claims.
