Referring to FIG. 1, the touch input sensing apparatus 100 is an example of a touch panel in which a driving electrode 111 and a sensing electrode 112 are formed by 30 channels along the first axis and the second axis, respectively. In this case, the touch sensing controller 120 may be configured by using three touch sensor chips 121 supporting 10x10 channels.

However, when the touch input sensing device 100 for use in a large-area display is implemented using a plurality of touch sensor chips 121, Noise or errors may occur due to interference with communication or other electronic devices, and space is required to be secured for mounting the touch sensor chips 120.

2 is a block diagram of a touch input sensing apparatus according to an embodiment of the present invention. 2, the capacitive touch input sensing apparatus 200 includes a touch panel 210 attached to an electronic device such as a display panel (not shown) to receive a touch input, And a touch sensing controller 220 for detecting a touch input generated in the touch panel 110. [

Generally, the touch input sensing device 200 is connected to an electronic device (not shown). The electronic device means a device disposed around the touch panel 210 and driven by a clock signal or a drive signal. For example, since the touch panel 210 is generally disposed on a display panel for displaying an image, the electronic device may be a display panel, or may be a voltage supply unit for supplying a voltage to the touch panel 210, The touch panel 210 may be an electronic device disposed outside the touch input sensing device 200 including the panel 210 and transmitting and receiving an electrical signal to and from the touch panel 210. [

The electronic device may be a display panel. The display panel is a panel for displaying an image. The display panel includes a liquid crystal display panel, an electrophoretic display panel, an organic light emitting diode panel, an LED panel, and an electro luminescent display panel Panel, a field emission display panel, a surface-conduction electron-emitter display panel, a plasma display panel (PDP), or a cathode ray tube (CRT) display panel. The touch panel 210 may be stacked on one side of the display panel. Although the electronic device is described as a display panel for convenience of description, the electronic device is not limited thereto and may be any electronic device capable of transmitting and receiving an electrical signal with the touch input sensing device 200. [

The touch panel 210 is disposed on a display panel for displaying an image, and receives a user's touch signal. The touch panel 210 is a panel for receiving a touch signal of a user, and may be implemented in various forms and is not limited to a specific form.

The touch panel 210 includes a plurality of driving electrodes 211 extending in a first axis direction and a plurality of sensing electrodes 212 extending in a second axis direction intersecting the driving electrodes 211, . The touch panel 210 may have a single layer structure in which a plurality of driving electrodes 211 and a plurality of sensing electrodes 212 are formed in a single layer in accordance with the electrode formation method, Layer structure in which the sensing electrodes 212 are respectively formed on a transparent substrate such as PET (polyethylene terephthalate), glass or plastic substrate, or the like. In this case, the plurality of driving electrodes 211 and the plurality of sensing electrodes 212 are electrically insulated from each other. When the driving electrode 211 and the sensing electrode 212 are formed in one layer, the overlapping portion of the driving electrode 211 and the sensing electrode 212 is isolated using a bridge or a separate insulating layer.

The touch panel 210 includes a plurality of divided regions 230 including at least a portion of a plurality of driving electrodes 211 formed on the touch panel 210. [ Each of the divided regions 230 may include the same number of driving electrodes 211 and may include driving electrodes 211 that are less than or equal to the maximum number of channels that the touch sensing control unit 220 can support.

Although the driving electrode 211 and the sensing electrode 212 are rectangular in one direction in the exemplary embodiment of the present invention, the shapes of the driving electrode 211 and the sensing electrode 212 are not limited thereto, The electrodes 211 and 212 may be formed in a shape in which a rhombic shape is repeatedly formed along a first axis or a second axis, a shape in which a straight line having a curvature is formed along a first axis or a second axis, a shape including a side- A shape in which a plurality of sub-electrodes are divided in parallel, or a shape in which each of the electrode shapes described above is applied in a variety of ways.

The touch sensing controller 220 sequentially applies a driving signal to the driving electrodes 211 of the touch panel 210 and receives a sensing signal from the sensing electrodes 212 of the touch panel 210. The touch sensing control unit 220 detects a change in mutual capacitance between the driving electrode 211 and the sensing electrode 212 at each position of the touch panel 210 from a plurality of received sensing signals, And determines the touch position.

The touch sensing control unit 220 may be mounted on the touch panel 210 and disposed on the same plane as the driving electrodes 211 and the sensing electrodes 212 of the touch panel 210. In some embodiments, the touch sensing controller 220 may be mounted on a separate circuit board other than the touch panel 210, and the circuit board on which the touch sensing controller 220 is mounted may be electrically connected to the touch panel 210 .

The touch sensing control unit 220 according to an embodiment of the present invention sequentially applies a driving signal to the driving electrodes 211 for detecting a region among the driving electrodes 211 and sequentially applies driving signals 211 If the driving electrode 211 in which the touch input is detected is present, the divided region 230 including the driving electrode 211 in which the touch input is detected is set as the detection target region, The driving signal is sequentially applied to all the driving electrodes 211 included in the detection target area and the coordinates of the touch input generated in the detection target area are calculated.

The driving electrode 211 for the area detection is set as a part of the driving electrodes 211 of the touch panel. The driving electrode 211 of the touch panel 210 may be a driving electrode 211 positioned at a specific relative position among the driving electrodes 211 included in the divided area 230 of the touch panel 210, The driving electrodes 211 may be positioned in a specific order based on the position where the driving electrodes 211 are formed.

In addition, the driving electrode 211 for detecting such a region is changed to another driving electrode 211 after a driving signal is applied. For example, after the driving signal is applied, the driving electrode 211 for area detection may be changed to the driving electrode 211 adjacent to the left or right of the driving electrode 211 for area detection.

The touch sensing control unit 220 may be configured to detect not only the detection target area but also the detection target area in order to maintain the linearity of the touch recognition when the touch input coordinate is detected by sequentially applying the driving signal to the driving electrodes 211 in the detection target area The driving signal may be sequentially applied to the driving electrodes 211 included in the adjacent divided regions 230 adjacent to the detection subject region to perform the detection operation of the touch input coordinates.

The touch sensing controller 220 may sense a part of the sensing electrodes 212 formed on the touch panel 210 without using the sensing electrodes 212 even when the sensing signal is received through the sensing electrode 212 after the driving signal is applied. It is possible to receive the sensing signal through the antenna.

The touch sensing controller 220 of the touch input sensing apparatus 200 according to an exemplary embodiment of the present invention performs an input area sensing operation for determining a divided area 230 where a touch input is generated, The touch input coordinate detection operation is performed in the touch input unit 230.

2 shows an example in which the input area of the touch panel 210 is divided into six divided areas 230. In Fig. Each of the divided regions 230 includes a part of a plurality of driving electrodes 211 formed on the touch panel 210. For example, when there are 100 driving electrodes 211 in the entire input area, each of the divided areas 230 includes 20 driving electrodes, and the touch panel can be divided into five divided areas 230 in total have.

The touch sensing controller 220 of the touch input sensing apparatus 200 according to an exemplary embodiment of the present invention first detects a touch input area among a plurality of driving electrodes 210 formed on the touch panel 210, And a drive signal is sequentially applied to the detection electrodes.

The area detection electrode is a driving electrode 211 for determining a divided area 230 where a touch input is generated on the touch panel 210. The area detection electrodes are set as driving electrodes 211 of some of the driving electrodes 211 formed on the touch panel 210. For example, one driving electrode 211 can be set as the area detecting electrode for each of five adjacent driving electrodes 211 formed on the touch panel 210. The number and position of the area detection electrodes can be variously changed according to the performance of the touch sensor chip and the touch detection speed required by the touch input sensing device.

Further, the region detecting electrode can be changed to another driving electrode 211 at the end or start of the driving signal applying operation of one cycle. For example, in the case where the leftmost driving electrode 211 is set as the area detecting electrode for every five adjacent driving electrodes 211 formed on the touch panel 210, The adjacent driving electrode 211 located on the right side of the current area detecting electrode among the five adjacent driving electrodes 211 formed on the touch panel 210 may be changed to be the area detecting electrode. That is, the position of the region detecting electrode can be sequentially changed at the end or start of each driving signal applying operation.

The method of setting the region detection electrodes will be described in more detail with reference to FIG. 4, which will be described later.

When the touch input is detected by the driving signal applied to the area detecting electrode, the touch sensing control unit 220 sets the divided area including the area detecting electrode as the detection target area. Then, drive signals are sequentially applied to all the drive electrodes 211 included in the detection subject region to calculate the touch input coordinates generated in the detection subject region. The operation of the touch input sensing apparatus according to an embodiment of the present invention will be described in detail with reference to FIG.

3 is a diagram illustrating a touch input sensing method according to an embodiment of the present invention. Referring to FIG. 3, the touch sensing controller 220 of the touch input sensing apparatus according to an exemplary embodiment of the present invention includes a plurality of driving electrodes (not shown) The driving signal is sequentially applied to the predetermined area detection electrodes.

In step 320, the touch sensing controller 220 determines whether the driving electrode 211 having the touch input is present through the sensing signal received after applying the driving signal in step 310. [ That is, in step 310, the touch sensing controller 220 sequentially applies a driving signal to the area detecting electrodes, receives a sensing signal from the plurality of sensing electrodes 212 of the touch panel, 211 and the sensing electrode 212 is detected. The touch sensing controller 220 can determine whether the touch input is generated and the touch input coordinates using the capacitance change. When the touch input is generated, the driving electrode 211, to which the driving signal is applied, (211).

If the driving electrode 211 in which the touch input has occurred does not exist in step 320, the operation proceeds to step 310 and the driving signal applying operation is repeatedly performed. In this case, the region detecting electrode can be changed.

If the driving electrode 211 in which the touch input is generated exists in step 320, the control proceeds to step 330 and sets the divided area including the driving electrode 211 in which the touch input has occurred as the detection target area.

In step 340, driving signals are sequentially applied to all the driving electrodes 211 included in the detection subject area, and in step 350, coordinates of the touch input generated in the detection subject area are calculated. If it is determined in step 360 that the touch input is canceled, the process proceeds to step 310. If the touch input is not released, the process proceeds to step 340. [

Meanwhile, in one embodiment of the present invention, an operation of detecting a touch input region is performed through operations of steps 310 to 330, and an input coordinate detection operation is performed through operations of steps 340 to 350. At this time, when the detection subject region is determined through the input region detection operation, the remaining divided regions 230 other than the detection subject region can perform the operation in Step 310 as it is. That is, a driving signal is sequentially applied to the area detecting electrodes of the respective divided areas 230, and the detecting operation of the divided area 230 is continuously performed to detect the multi-touch input. For example, referring to FIG. 2, each of the divided regions 230 performs an input region detection operation before an initial touch input occurs. When the touch input is generated, the divided area 230 where the touch input is generated is determined as the detection subject area, and the corresponding area performs the input coordinate detection operation. At this time, the remaining divided regions 230 other than the detection subject region continuously perform the input region detection operation.

Meanwhile, the touch input sensing apparatus 200 of the present invention performs input region detection for detecting an area where a touch occurs by sequentially applying a driving signal to each of the area detecting electrodes of the touch panel 210, When the region 230 exists, sensing is performed to sense the touch input through all the driving electrodes of the corresponding region 230 to calculate touch input coordinates. However, when the input coordinate is moved to another divided area 230 out of the divided area 230 where the first touch is generated due to the operation such as dragging during touch input, the touch input coordinates in the other divided area 230 are detected The input region detection and the input coordinate detection operation must be performed again, so that the linearity of the continuous touch input may be reduced. Accordingly, in one embodiment of the present invention, the input coordinate detection operation can be performed not only on the divided region 230 where the touch occurs, but also on the other divided region 230 adjacent to the corresponding divided region 230. In this case, even when the touch input coordinate moves out of the divided area 230 where the first touch is generated and moves to a neighboring divided area, the touch input coordinates can be continuously detected, and thus the linearity can be maintained.

4 is a view showing an example of a region detecting electrode of a touch panel according to an embodiment of the present invention. FIG. 4 is an enlarged view of a part of the left upper end of the touch panel 210 according to the embodiment of the present invention shown in FIG.

As shown in FIG. 4, the touch panel 210 according to an exemplary embodiment of the present invention includes five driving electrodes 211 to form one divided region 450. In this case, the driving electrodes 211 located at specific positions in the five driving electrodes 211 can be set as the area detecting electrodes. After the driving signal is applied once or a predetermined number of times, the region detecting electrode may be changed to the driving electrode 211 positioned on the right or left of the previous region detecting electrode.

For example, when the leftmost drive electrodes 401 and 406 are set as the area detection electrodes among the first five drive electrodes, the drive electrodes 402 and 407 positioned on the right side of the drive electrodes 401 and 407, .

On the other hand, when the driving electrodes 405 and 410 located at the rightmost position in the divided area 230 are the area detecting electrodes, the driving electrodes 401 and 406 located at the leftmost position in the divided area 230, The region detection electrode can be obtained. As described above, the driving electrodes 211 can be sequentially set as the region detecting electrodes in a form of circulating in the divided region 230.

In addition, the area detecting electrodes of the touch panel 210 according to an embodiment of the present invention may include driving electrodes 211 located in a specific order on the basis of a position where the electrodes are formed among the driving electrodes 211 on the touch panel, . For example, the driving electrode 401 located at the leftmost one among the driving electrodes 211 on the first touch panel 210 and the driving electrodes 404, 407, and 410 positioned every third from the driving electrode 401 And can be set as a region detecting electrode. In this case, one or more region detecting electrodes are present in one divided region 230.

In addition, when the driving electrodes 211 are driven once or a predetermined number of times, the driving electrodes 211 located on the left or right of the current area detecting electrodes may be set as the area detecting electrodes.

Though 30 driving electrodes and 30 sensing electrodes are formed on the touch panel 210 according to an embodiment of the present invention, the number of electrodes of the touch panel is determined by the size of the display to which the touch input sensing device is attached, The accuracy of the input, the use of the electronic device, and the like. Accordingly, the method of forming the area detecting electrode and the changing operation can be variously changed depending on the forming structure of the electrodes.

5 is a diagram illustrating an example of a method of setting a divided area of a touch panel according to an embodiment of the present invention.

The touch sensing controller 220 according to an embodiment of the present invention sequentially applies a driving signal to each of the driving electrodes in step 310 and 340 of FIG. 2, and receives a sensing signal through the sensing electrode. The touch sensing controller 220 may receive a sensing signal from all the sensing electrodes formed on the touch panel 210. [

As another example of receiving the sensing signal of the present invention, the touch sensing controller 210 may receive the sensing signal only from a predetermined portion of the sensing electrodes 212 among the sensing electrodes 212 formed on the touch panel 220 have. In this case, when receiving the sensing signal from the sensing electrodes 212, the touch sensing controller 210 receives the sensing signal from the predetermined sensing electrodes without receiving the sensing signal from all the sensing electrodes 212.

The representative sensing electrodes can be set as the sensing electrodes 212 positioned in a specific order based on the position where the electrodes are formed, among the sensing electrodes 212 on the touch panel. For example, referring to FIG. 5, a sensing electrode 501 located at the uppermost one of the sensing electrodes on the touch panel and sensing electrodes 504, 507, and 510 located every third in the downward direction from the sensing electrode 501 ) Can be set as a representative sensing electrode.

In addition, such a representative sensing electrode may be periodically changed. For example, after the sensing electrodes 212 transmit sensing signals one time or a predetermined number of times, the sensing electrodes 212 positioned on the upper or lower side of the currently set representative sensing electrodes may be set to be changed to the representative sensing electrodes.

Meanwhile, as described in one embodiment of the present invention, the touch sensing control unit 220 detects an input region in which a touch occurs by dividing an area of the touch panel by the driving electrode, and detects input coordinates in the detected object dividing region . Similarly, in an embodiment of the present invention, a plurality of divided regions including a part of a plurality of sensing electrodes 212 are determined, a divided region in which touch input occurs in a plurality of divided regions is determined first, The touch input coordinates can be calculated by receiving a sensing signal from all the sensing electrodes 212 formed in the region.

Although the exemplary embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
