Description

[0001] The present invention relates to a capacitive touch panel and a touch screen,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a capacitive touch panel and a touch screen, and more particularly, to a touch panel and a touch screen capable of preventing moire phenomenon due to optical interference between patterns.

The touch input apparatus is an input / output means for sensing the user's touch position on the display screen and receiving information about the sensed touch position to perform overall control of the electronic apparatus including the display screen control. The touch input apparatus includes an object such as a finger or a touch pen And recognizes it as an input signal when it comes into contact with the screen. Recently, touch input devices have been widely used in mobile devices such as a mobile phone, a PDA (Personal Digital Assistants), a PMP (Portable Multimedia Player), and the like. Input-supported desktop computers, Internet Protocol TV (IPTV), state-of-the-art fighters, tanks, and armored vehicles.

Such a touch input device is classified into a resistive type, a capacitive type, and an electro-magnetic type according to a method of sensing a touch. Two typical methods are resistive and capacitive.

The resistive method consists of two substrates coated with a transparent electrode. When a pressure is applied through a finger or a pen, the substrate in the area sticks to each other and the position is recognized.

The electrostatic capacity type is a method using the principle of detecting the static electricity generated in the human body, and is characterized by high durability, good permeability and quick reaction time. However, there is a disadvantage that the price is expensive and the gloves can not be manipulated. Typically, a capacitive touch panel according to the conventional method forms a sensing and operation sensor by patterning an ITO (Indium Tin Oxide) transparent electrode. However, since the touch sensing panel is expensive and the touch sensitivity is not good due to the high non- There is difficulty in compacting.

To solve this problem, a capacitive touch panel has recently been proposed which forms an electrode pattern with a conductive material having a lower resistance than ITO to improve visibility, touch sensitivity, and size. However, in this method, a moire phenomenon occurs due to optical interference between the electrode pattern and the pixel pattern or between the stacked electrode patterns, and the brightness of the touch screen is lowered due to opacity of the electrode pattern.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In the following description and the accompanying drawings, substantially the same components are denoted by the same reference numerals, and redundant description will be omitted. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

FIG. 1 illustrates an example of a configuration of an existing touch panel for facilitating understanding of the present invention. Referring to FIG. 1, the touch panel 1 has a structure in which a first sensor layer 10 and a second sensor layer 20 are laminated. The first sensor layer 10 is formed on a y- And the second sensor layer 20 serves to sense the position on the x-axis (horizontal) of the touch input. When the touch panel 1 is viewed from above, the first sensor layer 10 may correspond to the upper layer and the second sensor layer 20 may correspond to the lower layer. On the contrary, the first sensor layer 10 may correspond to the lower layer, 2 sensor layer 20 may correspond to the upper layer.

The first sensor layer 10 includes a plurality of sensor electrodes D1L1, D1L2 and D1L3 formed in the lateral direction and each of the sensor electrodes D1L1, D1L2 and D1L3 is formed on the surface of the touch panel 1 And a connecting region R2 connecting the sensing region R1 with the sensing region R1. The sensing region R1 and the connection region R2 are repeated in the horizontal direction at the corresponding sensor electrode. As shown in the figure, the sensing region R1 may be a grid pattern in which two mutually intersecting lines intersect, and the connection region R2 may be a pattern of lines in one of the two directions. However, the connection area R2 may have a grid pattern in which lines of two directions, which are the same as or similar to the sensing area R1, cross each other. The patterns of the sensing region R1 and the connecting region R2 are formed of a conductive material. For example, patterns may be formed in the first sensor layer 10 at a negative angle, and the pattern formed may be filled with a conductive material.

Unlike the first sensor layer 10, the second sensor layer 20 has a plurality of sensor electrodes D2L1, D2L2, and D2L3 formed in the longitudinal direction, and the sensing region R3 and the connection region R4 are formed in the longitudinal The structure is substantially the same as that of the first sensor layer 10. [

The sensing area R1 of the first sensor layer 10 and the sensing area R3 of the second sensor layer 20 are arranged so as not to overlap each other in the vertical direction of the first and second sensor layers 10 and 20 . That is, when the touch panel 1 is viewed from above, the sensing region R3 of the second sensor layer 20 is formed in the region 11 where the pattern of the sensor electrode is not formed in the first sensor layer 10, The sensing region R1 of the first sensor layer 10 is formed in the region 21 of the second sensor layer 20 where the pattern of the sensor electrode is not formed.

FIG. 2 shows another example of the structure of an existing touch panel for facilitating understanding of the present invention. Referring to FIGS. 1 and 2, the touch panel 2 of FIG. 2 is different from the touch panel 1 of FIG. 1 in that regions 11 and 21 in which no pattern of the sensor electrode is formed in FIG. The same or similar pattern as that of the sensing region R1 is formed in the sensing region R1, thereby reducing the visibility of the electrode pattern. An area where such a pattern is formed will be referred to as a dummy area in this specification. Referring to FIG. 2, the patterns of the dummy regions 12 and 22 are electrically insulated from the patterns of the sensing region and the connection regions R1, R2, R3, and R4. That is, the pattern of the sensing area and the connection areas R1, R2, R3, R4 and the patterns of the dummy areas 12, 22 appear to have continuity, but actually the pattern is broken at the boundary.

FIG. 3 is a view for explaining a moire phenomenon that may occur in the conventional touch panels. The moire phenomenon refers to a natural interference phenomenon formed when two independent periodic patterns are stacked. The moiré phenomenon occurs in the form of wave-like waves, ripples, and small wisps. As shown in FIG. 3, the Moire phenomenon occurs due to mutual interference between the pattern 50 formed by the pixels of the image display unit and the pattern 60 formed on the first sensor layer and / or the second sensor layer . Further, in the touch panel 20 of FIG. 2, the patterns formed on the first sensor layer 30 and the patterns formed on the second sensor layer 40 are stacked, and thus, they may be generated due to mutual interference.

The moire phenomenon may be generated by forming the pattern 60 of the first sensor layer and / or the second sensor layer at a predetermined angle with the pattern 50 formed by the pixels of the image display portion, And the pattern of the second sensor layer 40 are twisted at a certain angle with each other. However, even if the angle of the pattern to be laminated is changed, the occurrence of the moire phenomenon can not be completely eliminated in that it is a laminate of periodic patterns. Accordingly, the present invention proposes a touch panel and a touch screen capable of remarkably reducing occurrence of moire phenomenon by forming an irregular pattern in the first sensor layer and / or the second sensor layer.

FIG. 4 shows a configuration of a touch panel and a touch screen according to an embodiment of the present invention. Referring to FIG. 4, the touch screen according to the present exemplary embodiment has a structure in which an image display unit 100, a first sensor layer 200, and a second sensor layer 300 are stacked. In addition, the touch panel according to the present embodiment has a structure in which the first sensor layer 200 and the second sensor layer 300 are laminated. The first sensor layer 200 may be an upper layer and the second sensor layer 300 may be a lower layer. In this embodiment, the second sensor layer 300 is an upper layer and the first sensor layer 200 is a lower layer. Of course it is.

The image display unit 100 includes an LCD (Liquid Crystal Display), a PDP (Plasma Display Panel), an OLED (Organic Light Emitting Diode), an AMOLED (Active Matrix Organic Light Emitting Diode) Or the like, but is not limited thereto.

1, the first sensor layer 200 senses the position of the touch input on the y-axis (vertical), and the second sensor layer 300 senses the position of the touch input on the x- And detects the position of the image on the screen. The first sensor layer 200 includes a plurality of sensor electrodes 210 formed in a lateral direction and the second sensor layer 300 includes a plurality of sensor electrodes 310 formed in a longitudinal direction . Each of the sensor electrodes has a connection area for connecting a plurality of sensing areas to a sensing area similar to that described with reference to FIG. In this embodiment, the sensing region and the connection region of the sensor electrode are formed of the irregular pattern proposed in the present invention, and the pattern of the sensor electrode is made of a conductive material. For example, the pattern of the sensor electrode may be a pattern in which irregular patterns are formed in the first sensor layer 200 and the second sensor layer 300 at an obtuse angle, and the pattern formed is filled with a conductive material. The irregular patterns proposed in the present invention will be described in more detail with reference to FIG. 5A. Hereinafter, the pattern of the sensor electrode 210 of the first sensor layer 200 will be described, but the same applies to the pattern of the sensor electrode 310 of the second sensor layer 300.

5A shows an example of a pixel pattern of the image display unit 100 and an irregular pattern 211 of the sensor electrode 210 according to an embodiment of the present invention.

As shown in the figure, the image display unit 100 includes a plurality of pixels, and the pixels are arranged in a predetermined pattern 110 to display an image. The pixels are composed of sub-elements representing R, G, and B, respectively.

In the embodiment of the present invention, the irregular pattern 211 of the sensor electrode 210 is not a grid pattern in which two lines in a certain direction intersect with each other as shown in Figs. 1 and 2, Assuming a virtual grid pattern, it is a pattern in which some of the segments connecting nodes that are intersections of lines in a virtual grid pattern are removed. Hereinafter, for convenience, a line segment connecting nodes in a virtual grid pattern is referred to as a nodal segment, and a pattern in which a part of nodal line segments are removed from a virtual grid pattern is referred to as a " partially segmented pattern " deleted pattern ". Therefore, some line removal patterns are removed from the imaginary grid pattern and have remaining line segments.

However, it should be noted that the concept of eliminating a node segment is not meant to physically remove an existing node segment, but may be applied to a virtual grid pattern to define an irregular pattern proposed in the present invention. .

5B is a diagram showing a virtual lattice pattern in which lines in two directions are mutually intersected. 5B, the direction of the imaginary grid pattern 212, that is, one direction of the lines forming the grid pattern 212, is inclined by a predetermined angle () from the arrangement direction of the pixel pattern. The angle is an angle for preventing the moire phenomenon caused by the stacking of the image display unit 100 and the sensor layer. The angle is determined by the size of the image display unit 100, the size of the pixel pattern, the electrode line width of the grid pattern 212, A pitch to be defined, and the like. For example, the electrode line width may be 1 to 10 m, and the pitch may be 100 to 600 m.

5A is a pattern in which some of the node segments shown by a dotted line among the node segments in the grid pattern 212 are removed, assuming a virtual grid pattern 212 as shown in FIG. 5B. Pattern. For example, referring to FIG. 5B, the node segment PQ connecting the node P and the node Q in the grid pattern 212 corresponds to one of the removed node segments. In other words, when a square constituting a lattice pattern is a unit rectangle, a pattern in which a part of the nodal line segments is removed from the lattice pattern is a unit rectangle or a shape in which two or more unit rectangles are combined The closed (closed) graphic form is a block, and the blocks are connected to one another along the sides.

5C is a reference diagram for explaining a node segment, a unit square, and a block. Referring to FIG. 5C, reference numeral U corresponds to a unit square, and each side of the unit square corresponds to a node segment. Reference numeral B1 (shown as a bold line for convenience) shows an example of a block in which four unit squares are combined as a result of removal of three node segments as shown in the figure. In addition, reference character B2 (shown as a bold line for convenience) shows another example of a block in which four unit rectangles are combined as a result of removing three node segments as shown in the figure.

Referring again to FIG. 5A, the block 213 is a block having a shape in which three unit squares are combined as a result of removing two node segments in the grid pattern 212, and the block 214 is a virtual grid pattern 212 The block 213 and the block 214 are connected to each other along the sides of the block 213. In this case, In other words, adjacent blocks and blocks share some sides of each other. This relationship also corresponds to another type of block 215 in which four unit squares are combined. Some of these line removal patterns are similar to blocks in a Tetris game, and may be referred to herein as a Tetris pattern in some cases. Here, the length of one side of the unit square, that is, the length of the nodal line segment corresponds to the pitch, may be 100 to 600 m, and preferably 200 to 500 m. In addition, the line width of some line segment removal patterns may be 1 to 10 m.

In addition, some of the nodes appearing in the virtual grid pattern 212 are explicitly distinguished also in some of the segment removal patterns 211 according to the present invention, Are not explicitly distinguished in the partial line elimination pattern 211 according to FIG. For example, the nodes P and Q in FIG. 5B are explicitly distinguished from the nodes P 'and Q' as their corresponding nodes in FIG. 5A, but the node R in FIG. The corresponding nodes are not explicitly distinguished. For the sake of clarity, the nodes that are not explicitly distinguished are labeled R 'in Figure 5a. However, since the nodes that are not explicitly distinguished as R 'in the characteristic of the one-minute segment elimination pattern can also be understood as nodes, this explicitly indistinguishable node of some segment elimination patterns is also included in the node I will explain.

In addition, although the node segments are clearly distinguished in the virtual grid pattern 212, some of the segment segments of the segment removal pattern 211 may be clearly distinguished or not. For example, referring to FIG. 5A, the node segment P 'S is explicitly distinguished, but P'R' is not explicitly distinguished. However, since a node segment that is not explicitly distinguished as P'R 'can be understood as a nodal line segment due to the characteristics of a partial segment elimination pattern, in the present specification, such an explicitly indistinguishable nodal line segment Which are included in the node segment.

Referring to FIG. 5A, unlike the case in which the direction of the grid pattern in FIGS. 1 and 2 coincides with the direction of the pixel pattern of the image display unit, a part of the line elimination pattern 211 is oriented in the direction of the pattern, And is inclined by a predetermined angle () from the direction of the pixel pattern. The inclination angle is an angle for preventing the moire phenomenon caused by the stacking of the image display unit 100 and the sensor layer as described above. The pixel pattern of the image display unit 100 and the pattern of the first sensor layer 200 are different from each other in the directions of the pixel pattern of the image display unit 100 and the second sensor layer 300, The patterns of the patterns are also different from each other. The angled angle of the pattern 211 of the first sensor layer 200 with respect to the pixel pattern and the angled angle of the pattern of the second sensor layer 300 may be the same or similar. That is, the patterns of the pattern 211 of the sensor electrode 210 and the pattern of the sensor electrode 310 may be the same or similar. However, the direction of the pattern of the pattern 211 of the sensor electrode 210 and the pattern of the sensor electrode 310 may be different.

6A shows a cross-sectional view of a first sensor layer 200 or a second sensor layer 300 according to one embodiment of the present invention. 6A is a sectional view taken along the line A-A in Fig. 5A for convenience of explanation. Referring to FIG. 6A, the sensor layer includes a substrate 200b, a resin layer 200a stacked on the substrate 200b and having a relief pattern patterned on a surface thereof with a line removal pattern, (216). The electrode layer 216 is formed by filling a conductive material in the recessed portion, and corresponds to a pattern of removing some segments of the sensor electrode.

FIG. 6B is a view for facilitating understanding of the present invention, and shows a cross section taken along the line B-B 'in FIG. 5B. 6A, the intaglio angle and the electrode layer corresponding to the portion indicated by the dotted line in FIG. 6A are present (FIG. 5B is a lattice pattern), but it does not exist in FIG. 6A.

In FIG. 6A, the electrodes of some line removal patterns are formed in the sensor layer at an obtuse angle, but it is needless to say that the electrodes of some line removal patterns may be formed in the sensor layer in a boss.

In the present embodiment, the substrate 200b is preferably a transparent substrate. That is, the transparent substrate is made of PET (polyethylene terephthalate), PI (polymide), acrylic, polycarbonate (PC), triacetate cellulose (TAC), polymethyl methacrylate (PMMA) , Polyethersulfone (PES), polyethylene naphthalate (PEN), or glass.

The resin layer 200a is laminated on the substrate and has a relief pattern patterned on a surface thereof in a partial line removal pattern. Specifically, a resin layer is laminated on a transparent substrate, and such a depressed shape is formed by imprinting the resin layer using a mold having a relief shape corresponding to a desired depressed shape. That is, a relief is formed on the resin layer by using a mold having a relief shape. Whereby one or more engraved patterns are formed in a pattern. The resin layer is preferably made of UV (ultraviolet) resin or thermosetting resin.

The electrode layer 216 is formed by filling a conductive material into the depressed angle. Examples of the conductive material include copper (Cu), silver (Ag), aluminum (Al), nickel (Ni), chromium (Cr) Phosphorus (Ni-P), or the like.

As described above, the moire phenomenon is a natural interference phenomenon that occurs when two independent periodic patterns are stacked. Therefore, if the sensor electrode is formed with a partial line removal pattern, irregular interference occurs due to the periodic pixel pattern and the irregular partial line removal pattern, so that the moire phenomenon is significantly reduced.

According to the embodiment of FIG. 5A, the direction of some line removal patterns is inclined at a certain angle with respect to the direction of the pixel pattern, but since some line removal patterns are irregular, the moire phenomenon can be reduced without inclining the direction. Therefore, according to another embodiment of the present invention, the direction of a part of the line removal pattern may be aligned with the direction of the pixel pattern without inclining with respect to the direction of the pixel pattern. In addition, in the case of the grid pattern, the tilt angle for preventing the moiré phenomenon needs to be precisely determined according to the specification of the size of the image display unit, the size of the pixel pattern, the electrode line width of the grid pattern, the pitch, The inclination angle should also be changed. However, if a certain line segment removal pattern is employed, sufficient moire phenomenon can be reduced even at an arbitrary inclination angle. Therefore, even if the size of the image display unit is changed, the inclination angle does not need to be changed, so that a general pattern design can be provided.

The line segment removal pattern according to the embodiment of the present invention is basically irregular and irregular in that a part of the line segments are removed from the grid pattern, A regular pattern may occur in some regions. And this regular pattern may cause moire phenomenon due to interference with other layers. Therefore, in the embodiment of the present invention, a certain line segment rule of some line segment removal patterns is introduced in order to block the occurrence of such regular patterns.

The first line rule is to ensure that no more than a certain number of nodal line segments in the same direction are connected. In other words, the first line rule is to prevent a relatively long line from appearing in some line removal patterns. This is because as the relatively long straight line appears in some line segment removal patterns, it forms a regular pattern in a certain region, and thus can cause moiré phenomenon with other patterns piled up.

For example, the first line rule is to ensure that there are no more than six consecutive nodal line segments in the same direction. In the case where the node segments of the same direction are not continuously connected to six or more, the examples satisfying the rule and the examples not satisfying the rule are as follows. The dashed line below is shown to show the node segments removed from the imaginary grid pattern.

In the form on the left above, the five node segments in the same direction are connected in series, but the sixth node segments are in different directions and thus satisfy the rule. However, the form on the right does not satisfy the rule because the six node segments in the same direction are connected in series.

In addition, the first line rule has a close relationship with the shape of the block. When the line segments of the same direction are not connected to six or more consecutive lines, the five unit rectangles The block satisfies the rule, but the block with the shape in which the six unit rectangles are connected in a straight line as shown in the right side below results in six consecutive nodal line segments in the same direction, so that the rule is not satisfied. The dashed line below is shown to show the node segments removed from the imaginary grid pattern.

The second line rule is to prevent two connected node segments having different directions from connecting repeatedly more than a certain number of times. In other words, the shape of the same shape is prevented from continuing more than a predetermined number of times. This second join rule prevents relatively long stepped shapes from appearing in some segment removal patterns. As the relatively long stepped shapes appear in some line segment removal patterns, this creates a regular pattern in a certain area, and thus can cause moiré phenomena with other patterns piled up.

For example, the second line rule is to ensure that the same shape of the shape does not occur more than four times. In this case, in the pattern on the left below, the same shape is continued three times, so the rule is satisfied. On the right pattern, however, the shape of the same shape is consecutive five times.

A partial segment removal pattern that is a pattern in which some of the nodal line segments in the virtual lattice pattern are removed may be a block shape in which one unit square or two or more unit squares are combined, Since they may be viewed as patterns connected to each other along the sides, they may be referred to as a tetris pattern.

In the embodiment of the present invention, the block constituting the tetris pattern is preferably a closed figure having a shape in which two or more unit squares are combined, but in some cases, one unit square may also be included in the block. That is, unit quadrangles may be included in the pattern according to the aspect that the node segment is removed based on the virtual grid pattern. This is because there are cases in which a continuous pattern can not be formed only by blocks having shapes in which two or more unit squares are combined. However, increasing the number of unit squares in the Tetris pattern means that the regularity of the pattern increases, so that the lower the ratio of the unit squares among the blocks, the better. The number of unit squares constituting one block is not particularly limited, but may be limited to, for example, six or less.

FIG. 7 shows an example of blocks constituting a Tetris pattern, and shows examples of possible blocks when a unit square constituting a block is, for example, three to six. In the example of the blocks shown in FIG. 7, blocks having a shape in which six unit squares that do not satisfy the first line rule are linearly joined are excluded. However, the shapes of FIG. 7 are merely examples, and there may be other shapes other than the illustrated shapes, and it is needless to say that there may be more various shapes depending on the number of unit squares.

That is, in the embodiment of the present invention, the rules for the line segment of some line removal patterns and the rules for the shape of the blocks constituting the line segment removal (or the tetris pattern) are defined.

The line segment rule is defined as follows, for example.

1. Ensure that there are no more than six consecutive nodal line segments in the same direction

2. Make sure that the shape of the same shape is not continuous more than 4 times

The rules for the shape of the block are defined as follows, for example.

1. One block consists of 3 to 6 unit squares

2. Excludes blocks of shapes in which only six unit rectangles are joined together in a straight line.

In the rule about the shape of the line rule or the block, under the intention to prevent the moire phenomenon, the number of consecutive nodal line segments or letter shapes, the number of blocks, and the like can be appropriately selected or changed, And these variations are included in the scope of the present invention.

However, it is somewhat difficult to design a line segment removal pattern satisfying 100% of the rule even if the rule for the line rule and the shape of the block are defined as above. Therefore, in the embodiment of the present invention, the portion that does not satisfy the rule is allowed, but the moire phenomenon is prevented by limiting the ratio to a certain ratio.

First, there are six or seventeen consecutive nodal line segments in the same direction and four or five consecutive serifs of the same shape in a form that does not satisfy the line segment rule. These forms will be referred to below as "dissatisfied segment connections" for convenience. In the embodiment of the present invention, it is assumed that there is no case where the same shape of the shape of the node is continuous six or more times in the case where the node segments in the same direction are continuously connected to eight or more.

Therefore, a certain line segment removal pattern can be designed so that the ratio of the line segments connecting the unsatisfied line segment to the number of line segments included in the entire line segment removal pattern is defined and the ratio is less than a predetermined value. Here, the entire partial line elimination pattern is a range which is a standard for calculating the above ratio, and may be a production unit of a mold for forming a partial line elimination pattern in the resin layer as described above, It may correspond to a partial line elimination pattern of the entire layer or may correspond to a partial line elimination pattern of one sensor electrode.

For example, it is possible to reduce the occurrence of the moire phenomenon sufficiently by making the ratio of the nodes connecting the unsatisfied line segments to the number of the line segments included in the entire line segment removal pattern to be 10% or less. Of course, the above ratio can be appropriately changed within the tolerance limit of occurrence of the moire phenomenon.

Also, there is a block which does not satisfy the rule regarding the shape of a block, and a block composed of one unit square and a block composed of two unit squares. These blocks are hereinafter referred to as unsatisfactory blocks for convenience. In the embodiment of the present invention, it is assumed that there is no block composed of seven or more unit squares for the sake of convenience.

Therefore, the ratio of unsatisfied blocks to the total number of blocks included in the entire Tetris pattern may be defined, and the Tetris pattern may be designed so that the ratio is less than a predetermined value. Here, the total Tetris pattern is a range that is a reference for calculating the above ratio, and may be a unit for producing a mold for forming a Tetris pattern in the resin layer as described above, Pattern, and may correspond to a tetris pattern of one sensor electrode.

For example, the ratio of the unsatisfied blocks to the total number of blocks included in the entire Tetris pattern may be 10% or less, thereby sufficiently reducing the occurrence of the moire phenomenon. Of course, the above ratio can be appropriately changed within the tolerance limit of occurrence of the moire phenomenon.

On the other hand, in a capacitive touch panel, it is preferable that the capacitance between the plurality of sensor electrodes constituting one sensor layer is uniform. In the case of the touch panel shown in FIG. 1 or FIG. 2, since each of the sensor electrodes has the same lattice pattern, the capacitance is naturally uniform. However, in the embodiment of the present invention, since some line removal patterns are basically irregular patterns, a difference in capacitance may occur between sensor electrodes. However, due to the nature of the capacitive touch input method, the electrostatic capacitance need not be exactly the same. Therefore, in the embodiment of the present invention, the electrostatic capacities of the plurality of sensor electrodes constituting one sensor layer can be made to be a predetermined ratio, for example, 20% or less based on the electrostatic capacitance of any one of the sensor electrodes . By making the difference in the electrostatic capacitance of the sensor electrodes within 20%, a sensing error due to the difference in capacitance can be sufficiently prevented.

A part of the line removal pattern has a part of the line segments corresponding to the electrodes removed from the grid pattern in comparison with the virtual grid pattern on which the line segment removal pattern is based and has the same meaning as the area of the conductive plate constituting the capacitor is reduced . Therefore, the sensor electrode of some line removal patterns has less capacitance than the sensor electrode of the lattice pattern (assuming that the electrode line width and pitch are the same), and the capacitance is based on the imaginary grid pattern The more the node segments are removed, that is, the fewer the node segments that form the segment removal pattern, the smaller the capacitance is.

Therefore, the capacitance increases as the number of the node segments forming the line segment removal pattern increases, and the capacitance decreases as the number of the node segments forming the line segment removal pattern decreases. As a result, it can be said that the electrostatic capacitance of the sensor electrode having a certain line segment removal pattern is proportional to the number of the broken line segments constituting the partial line segment removal pattern.

Therefore, in the embodiment of the present invention, by uniformizing the number of nodal line segments constituting the corresponding line segment removal pattern for each sensor electrode, it is possible to have a uniform electrostatic capacity for each sensor electrode. However, it is not necessary that the electrostatic capacitances exactly coincide with each other as described above. For example, it may be sufficient that the electrostatic capacitance does not deviate from the range of 20% based on the electrostatic capacity of any one of the sensor electrodes. Therefore, in this case, the uniformity of the electrostatic capacitance can be satisfied by making the number of nodal line segments constituting a part of the line elimination pattern for each sensor electrode not to deviate from a predetermined ratio, for example, 20% range based on the value of any one sensor electrode . Of course, the error ratio of the capacitance or the error ratio of the number of node segments can be appropriately changed within the limit of correct touch recognition.

FIG. 8 shows a configuration of a touch panel and a touch screen according to another embodiment of the present invention. Referring to FIG. 8, the touch screen according to the present exemplary embodiment has a structure in which an image display unit 100, a first sensor layer 400, and a second sensor layer 500 are stacked. In addition, the touch panel according to the present embodiment has a structure in which the first sensor layer 400 and the second sensor layer 500 are laminated. In this embodiment, the second sensor layer 500 is shown as an upper layer and the first sensor layer 400 is shown as a lower layer. In contrast, when the first sensor layer 400 is an upper layer and the second sensor layer 500 is a lower layer Of course.

4, the first sensor layer 400 is responsible for sensing the position on the y-axis (vertical) of the touch input and the second sensor layer 500 is for sensing the position on the x- (Horizontal) position. The first sensor layer 400 includes a plurality of sensor electrodes 410 formed in a lateral direction and the second sensor layer 500 includes a plurality of sensor electrodes 510 formed in a longitudinal direction . Each of the sensor electrodes has a connection area for connecting the plurality of sensing areas and the sensing area, similar to the sensor electrodes of FIG. Further, in the present embodiment, the first sensor layer 400 and the second sensor layer 500 may be formed by forming a pattern similar to that of the sensing region in a region where the pattern of the sensor electrode is not formed, Thereby reducing the visibility of the electrode pattern. That is, in this embodiment, dummy electrodes 420 and 520 are electrically insulated from the sensing area and the connection area, respectively, in each sensor layer as compared with the embodiment shown in FIG.

In the present embodiment, the sensing area and the connection area of the sensor electrode, and the dummy electrodes 420 and 520 are made up of some line removal patterns proposed in the present invention. The pattern of the dummy electrodes 420 and 520 of the sensing electrode and the connecting region of the sensor electrode are formed such that a part of the line removing pattern as described above is formed in the first sensor layer 400 and the second sensor layer 500 And the pattern formed may be filled with a conductive material. However, the patterns of the sensing area and the connection area and the patterns of the dummy electrodes 420 and 520 appear to have continuity, but actually the pattern is broken at the boundary.

5A, the pixel pattern of the image display unit 100 and the pattern of removing the line segments of the sensor electrode 410 and the dummy electrode 420 of the first sensor layer 400 are different from each other in direction, The pixel patterns of the display unit 100 and the sensor electrode 510 of the second sensor layer 500 and the line segment removal patterns of the dummy electrode 520 are also mutually different in direction. Furthermore, in the present embodiment, a portion of the line segment removal pattern of the first sensor layer 400 and a line segment removal pattern of the second sensor layer 500 are also deviated from each other. This is because the pattern of the first sensor layer 400 and the pattern of the second sensor layer 500 overlap each other when the touch panel is viewed from the top (specifically, the detection of the sensor electrode 410 of the first sensor layer 400) The dummy electrode 520 of the second sensor layer 500 overlaps the sensing area of the dummy electrode 420 of the first sensor layer 400 and the sensing electrode 510 of the second sensor layer 500, ) To prevent moire phenomenon due to interference between the pattern of the first sensor layer 400 and the pattern of the second sensor layer 500.

9 shows an example of a partial segment removal pattern 411 of the first sensor layer 400 and a partial segment removal pattern 511 of the second sensor layer 500 stacked according to an embodiment of the present invention . For the sake of convenience, the pixel pattern of the image display unit 100 is not shown, and the direction of the pixel pattern is the horizontal and vertical directions.

9, a portion of the line segment removal pattern 411 of the first sensor layer 400 is inclined by a first angle () with respect to the pixel pattern, and a portion of the line segment removal pattern 511 Is inclined by the second angle () with respect to the pixel pattern. In other words, one direction of a node segment constituting part of the line segment removal pattern 411 of the first sensor layer 400 is inclined by a first angle () with respect to the pixel pattern, One direction of the node segment constituting the pattern 511 is inclined by the second angle () with respect to the pixel pattern. In addition, a part of the line segment removal pattern 411 of the first sensor layer 400 and a part of the line segment removal pattern 511 of the second sensor layer 500 are angularly deformed. That is, one direction of a node segment constituting a part of the line segment removing pattern 511 of the second sensor layer 500 is an angle (angle) with respect to one direction of a line segment of the line segment removing pattern 411 of the first sensor layer 400 - tilted as much as.

The pattern of the sensor electrode 410 and the dummy electrode 420 of the first sensor layer 400 may be formed in a partial line removal pattern and the sensor electrode 510 of the second sensor layer 500, Moire phenomenon caused by interference between the pattern of the first sensor layer 400 and the pattern of the second sensor layer 500 is remarkably reduced by forming the pattern of the electrode 520 in a partial line removing pattern.

In another embodiment of the present invention, the length of a node segment constituting a part of the line segment elimination pattern 411 of the first sensor layer 400 and the length of the line segment segment constituting the partial line segment removal pattern 511 of the second sensor layer 500 The length of the node segment may be different. For example, the length of a node segment constituting a part of the line segment removing pattern 511 of the second sensor layer 500 is made larger than that of the first sensor layer 400, thereby enlarging the size of the blocks as a whole. For example, the length of a node segment constituting a part of the line segment removal pattern 411 of the first sensor layer 400 is defined as 250 m, and the length of a line segment segment constituting the partial line segment removal pattern 511 of the second sensor layer 500 is defined as 250 m. Can be defined as 350 m. By varying the lengths of the node segments for each of the line segment removal patterns of the first sensor layer 400 and the second sensor layer 500 as described above, the pattern of the first sensor layer 400 and the pattern of the second sensor layer 500 The mutual interference can be further reduced, and the moire phenomenon can be further reduced. Further, if the length of one of the first and second sensor layers 400 and 500 is increased, the light transmittance of the sensor layer having a longer length of the node segment increases, The brightness of the screen is further improved.

9, the direction of the pattern of the first sensor layer 400 and the pattern of the second sensor layer 500 are changed at a certain angle. However, since some of the line removal patterns are irregular patterns, It is possible to reduce the moiré phenomenon without turning the switch. Therefore, according to another embodiment of the present invention, it is possible to match the direction of some line segment removal patterns of the first sensor layer 400 and the line segment removal patterns of the second sensor layer 500, It is possible.

In addition, if the pattern of the first sensor layer 400 and the pattern of the second sensor layer 500 are formed in a lattice pattern, the inclination angle of the inter-sensor layer pattern for preventing the moire phenomenon may be varied depending on the electrode line width of the lattice pattern, Etc., and if the specification changes, the tilt angle should also be changed. However, if a certain line segment removal pattern is employed, sufficient moire phenomenon can be reduced even at an arbitrary tilt angle. Therefore, even if the line width or pitch of the line segment removal pattern is changed, for example, the inclination angle does not need to be changed, so that a general pattern design can be provided.

8 and 9, the uniformity of the electrostatic capacitance can be satisfied by making the number of the node lines constituting the corresponding line segment removal pattern to be within a certain range for each sensor electrode as described above. However, since the dummy electrode does not perform the sensing function, the uniformity of the electrostatic capacitance may not be satisfied.
