Description

A circular touch panel {Circle Shape Touch Panel}

The present invention relates to a circular touch panel.

Currently, the sensing methods used in touch screens are mainly composed of resistive film type, surface ultrasonic type, and capacitive type. Of these, capacitive type is superior in durability and visibility, and thus adopted as a main input means of portable mobile devices .

The capacitive touch screen recognizes the user input by sensing the change in the amount of charge charged on the capacitive sensors on the touch screen panel due to user intervention, and recognizes the user input by self-capacitive type according to the charge storage method. And mutual-capacitive. The self-capacitance scheme constitutes one conductor per capacitive sensor to form a reference ground and a charging surface outside the touch screen panel.

Conventional circular touch screen panels detect the touch of an object by forming hexagonal or rectangular touch sensing electrodes on a transparent circular substrate. According to the circular touch screen panel of the related art, a hexagonal or rectangular pattern can not be formed in the vicinity of the circular shape, so that a region where touch is not detected is distributed.

The main object of the present invention is to provide a circular touch panel capable of detecting a touch with high sensitivity and accuracy not only in the center portion but also in the vicinity of the circumference.

The touch panel according to the present embodiment includes a circular substrate, a first finger pattern disposed in the center direction around the circular substrate and including a plurality of first fingers extending in a first direction along the circumference, And a second finger pattern disposed in a center direction and extending in a second direction along the circumference and comprising a plurality of second fingers interdigitated with the first fingers, The finger pattern forms an annular sector shape.

The touch panel according to the present embodiment includes a circular substrate, a plurality of A fingers extending in the first direction along the circumference and each disposed in the center direction around the circumference, and a plurality of A fingers extending in the second direction along the circumference, And a second pattern comprising a plurality of second fingers each extending in a second direction and interdigitating with A fingers and disposed in a central direction about the periphery, And a third pattern each including a plurality of third finger patterns extending in a first direction and interdigitating with the B fingers and disposed in a central direction around the finger.

According to the present embodiment, since patterns capable of detecting touch are formed not only in the inside but also around the circumference of the circular touch panel, it is possible to solve the problem of the related art that the touch can not be detected in the vicinity of the circumference. In addition, according to this embodiment, since the patterns forming the partial circles of the quadrant, the quadrant, and the semicircle are used, the touch of the object and the movement of the object can be detected with high sensitivity and accuracy. In addition, according to the present embodiment, since the touch by the object is detected with a small number of patterns as compared with the conventional art, there is also provided an advantage that the number of conductors connecting the pattern and the detection unit is reduced.

In the present specification, an annular sector shape refers to a shape obtained by only obtaining a portion having a desired central angle in a ring shape formed by a circle having a common center but two different radii It says. As an example, the partial annulus of a quadratic circle means that only a portion having a central angle of 90 degrees in the ring is obtained. Thus, the partial annulus of the quadrants has a central angle of 90 degrees and can be described as a part of the fan with radius r1, which has the same center and the same central angle, but with the radius r2 (r1> r2) removed. It is natural that the central angle of the partial ring can be larger than 180 degrees.

In this specification, the fact that the pattern extends in one direction means that the pattern is not broken in one direction, and that the width of the pattern decreases as the pattern proceeds in one direction.

1st Example

1 is a diagram showing an outline of a circular touch panel according to the present embodiment. In FIG. 1, for the sake of easier understanding, only four quadrants are shown in different colors in the circular touch panel. Referring to FIG. 1, the circular touch panel according to the present embodiment includes a circular substrate, a plurality of first fingers 110a, 110b, and 110c that are arranged in the center direction around the circular substrate and extend in a first direction along the circumference ) And a first finger pattern 110 disposed in a center direction around the circular substrate and extending in a second direction along the circumference to interdigitate with the first fingers 110a, 110b, and 110c And a second finger pattern (120) including a plurality of second fingers (120a, 120b, 120c), wherein each of the fingers is interdigitated, wherein the first finger pattern and the second finger pattern have a partial annular shape annular sector shape.

A first finger pattern 210 and a second finger pattern 220 are positioned on one side of the substrate 100. In one embodiment, when the touch panel according to the present embodiment is mounted on a display panel to form a touch screen, the substrate may be transparent to transmit visual information displayed on the display panel. For example, the substrate is a glass substrate. As another example, the substrate may be a transparent PET (polyethylene terephthalate) film. As another example, which is not illustrated, the substrate can be used as a substrate if it is a transparent material that can transmit the visual information provided by the display located on the backside.

The first finger pattern 110 includes a plurality of first fingers 110a, 110b, and 110c extending in a first direction, and the second finger pattern 120 includes a plurality of second fingers 110a, (120a, 120b, 120c). The first finger pattern 110 and the second finger pattern 120 are interdigitated with each other and the first finger pattern and the second finger pattern including each of the fingers arranged in an interdigitated arrangement form a partial annular shape annular sector shape, 115).

Each of the patterns including the first finger pattern 110 and the second finger pattern 120 is formed of a transparent material. In order to implement a touch screen using the touch panel according to the present embodiment, patterns to be provided with a touch input from a user must also be transparent. For example, the patterns provided with a touch input are formed of a transparent conductive material such as ITO (Indium Tin Oxide), IZO (Indium Zinc Oxide), AZO (Aluminum Zinc Oxide), and ICO (Indium Cadmium Oxide). In another example, the patterns may be formed of a CNT film (Carbon Nano Tube Film). The CNT film can flow a current having a higher density than a transparent conductive material such as ITO.

In one embodiment, the first finger pattern 110 includes a plurality of first fingers 110a, 110b, and 110c. The second finger pattern 120 includes a plurality of second fingers 120a, 120b, and 120c. 1, the first finger pattern 110 includes three fingers 110a, 110b, and 110c, and the second finger pattern 120 includes three fingers 120a, 120b, and 120c ), But these are examples only, and the number of fingers included in each pattern may vary.

The first fingers 110a, 110b, and 110c and the second fingers 120a, 120b, and 120c are interleaved with each other. As will be described later, since the fingers are arranged in a pod, the touch coordinates by the object can be detected, and even when the position of the object providing the touch input changes, the change of the touch coordinates can be tracked more precisely.

In the embodiment shown in FIG. 1, the first finger pattern 110 and the second finger pattern 120 form a partial annulus 115 of eight quarters. According to another embodiment, the first finger pattern and the second finger pattern may form a circular ring segment that is larger or smaller than an eight-ring circular. The third finger pattern 130 and the fourth finger pattern 140 also include a plurality of fingers (not shown), and the fingers included in the third finger pattern 130 and the fourth finger pattern 140, Are placed interdigitally with one another. The third finger pattern 130 and the fourth finger pattern 140 form an eight-part circular annulus 155. The first finger pattern 110 and the second finger pattern 120 may form an eight-channel annulus 115, a third finger pattern 130, and a fourth annulus.

According to this embodiment, the touch input on the touch panel is detected as patterns forming a partial circle of 8 minutes. This pattern has an advantage in that the movement of the object providing the touch input can be detected with high sensitivity and high accuracy because the pattern width variation with respect to the pattern length is larger than the patterns forming the quadratic or semi-circular partial rings / RTI >

In the embodiment shown in FIG. 1, the fifth finger pattern 150 and the sixth finger pattern 160 each include a plurality of fingers (not shown), and the fifth finger pattern 150 and the sixth finger pattern 160 The fingers included in the pattern 160 are interleaved with one another. In the embodiment shown in FIG. 1, the fifth finger pattern 150 and the sixth finger pattern 160 are shown to include three fingers, respectively. However, these are only illustrative, and the number of fingers included in each pattern may vary.

The fifth finger pattern 150 and the sixth finger pattern 160, which are interdigitated with each other, form a four-member circular ring. In one embodiment, the fifth finger pattern 150 and the sixth finger pattern 160 may be disposed in a hollow of a quadratic part circular formed by the first through fourth finger patterns, To 6 < th > finger patterns can consequently form a four-membered circular ring.

1, the first fan-shaped pattern 170 and the second fan-shaped pattern 180 are formed by a fourth fingerprint pattern 150 formed by the fifth finger pattern 150 and the sixth fingerprint pattern 160, And is located in the hollow. In the illustrated embodiment, the first fan-shaped pattern 170 and the second fan-shaped pattern 180 each have a fan shape of eight quarters, but this is only one example, and the central angle of the fan shape may be modified for each embodiment.

In the embodiment shown in FIG. 1, the first to sixth finger patterns and the first and second fan patterns may form any one of the four regions of the circular touch panel. This is a simple embodiment, and a typical artisan can form a touch panel in which a circular touch panel is divided into n (n: natural numbers) based on the above-described embodiment.

In one embodiment, in the touch panel quadrangle formed by the first to sixth finger patterns and the first and second fan patterns, an electric signal is given to each finger pattern and a sector pattern adjacent to both sides except the arc A wire is formed that can be received. In one embodiment, the conductive lines may be formed together in the patterning process to form the first to sixth finger patterns and the first and second fan-shaped patterns with the same material as the respective patterns. In another embodiment, the wire may be a metal wire such as silver wire or gold wire.

Unlike the first to sixth finger patterns each having a plurality of fingers, the first and second fan-shaped patterns 170 and 180 each have an eight-quadrant shape. If a finger pattern having a plurality of fingers interdigitated in the central portion of the touch panel (see FIG. 3B3) is formed, the width of the finger is finely formed, so there is a problem of sensitivity degradation . Further, the amount of movement of the object to be detected at the central portion (see Fig. 3B3) is finer than the movement of the object along the circumference at the outer frame portion of the touch panel (see Fig. 3B1 position). Therefore, it is more preferable in terms of sensitivity to detect the touch and movement of the object by forming a plurality of fan-shaped patterns at the central portion as in this embodiment.

2 is a diagram for explaining a process of detecting a touch using the touch panel according to the present embodiment when an object providing touch input moves in a circumferential direction along an arrow. Referring to FIG. 2, a cross section of an object providing a touch input to a touch panel is indicated by a circle (F).

The ratio of the first finger pattern 110 occupying the object section F is larger than the ratio of the second finger pattern 120 occupying the object section F when the object is at the A1 position. When the object is touched at the position A1, the amount of capacitance change formed between the first finger pattern 110 and the object is larger than the amount of capacitance change formed between the second finger pattern 120 and the object. Accordingly, the detection unit (not shown) for detecting the touch can calculate the ratio of the capacitance change amount of the first finger pattern 110 to the capacitance change amount of the second finger pattern 120, thereby determining the position of the object performing the touch.

As the object moves along the arrow, the rate at which the first finger pattern 110 occupies the cross-section F of the object decreases and the rate at which the second finger pattern 120 occupies the cross-section F of the object increases. The ratio of the second finger pattern 120 occupying the section F of the object is larger than the ratio of the first finger pattern 110 occupying the section F of the object when the object moves to the A2 position, The ratio of the third finger pattern 130 occupying the cross section F of the object is larger than the ratio of the finger pattern 140 occupying the cross section F of the object. The ratio of the second finger pattern 120 occupying the cross section F of the object and the third finger pattern 130 occupying the cross section F of the object are similar. Accordingly, when the object provides the touch input at the position A2, the detection unit (not shown) for detecting the touch detects the capacitance change amount of the first to fourth finger patterns generated by the touch of the object, have.

As the object moves along the arrow, the ratio of the first finger pattern 110 and the second finger pattern 120 occupying the object section F decreases, and the third finger pattern 130 and the fourth finger pattern 120 140) occupies the cross-section (F) of the object increases. The ratio of the fourth finger pattern 140 occupying the section F of the object is larger than the ratio of the third finger pattern 130 occupying the section F of the object when the object moves to the A3 position. Therefore, the change in capacitance caused by the touch of the object is larger in the fourth finger pattern 140 than in the third finger pattern 130. The detection unit (not shown) may detect the position of an object performing a touch by detecting a capacitance change amount of the third finger pattern 130 and the fourth finger pattern 140, which are generated by the touch of an object.

3 is a diagram for explaining a process of detecting a position of an object when a touching object moves in a direction from a circumference to a center along an arrow in the touch panel according to the present embodiment. Referring to FIG. 3, when the object is at the B1 position, the ratio of the first through fourth finger patterns occupying the object section F is similar to each other. Therefore, when the touch is performed by the object, the amounts of change in capacitance formed between the first to fourth finger patterns and the object are all similar. Therefore, the detection unit (not shown) for detecting the touch can calculate the ratio of the capacitance variation of the first to fourth finger patterns to determine the position of the object performing the touch.

As the object moves along the arrow, the ratio of the first to fourth finger patterns occupying the cross section F of the object decreases and the fifth finger pattern 150 and the sixth finger pattern 160 cross the object's cross section F ) Is increased. When the object moves to reach the B2 position, the first to fourth finger patterns do not occupy the cross section of the object, and the fifth finger pattern 150 and the sixth finger pattern 160 have a cross- (F). Therefore, the change in the capacitance caused by the touch of the object is similar to each other in the fifth finger pattern 150 and the sixth finger pattern. The detection unit (not shown) can detect the position of the object by detecting a capacitance change occurring in the fifth finger pattern 150 and the sixth finger pattern 160.

As the object further moves along the arrow, the ratio of the fifth finger pattern 150 and the sixth finger pattern 160 occupying the object's cross-section F decreases, and the ratio of the first and second fan- The ratio of the object 180 occupying the cross section F of the object increases. When the object reaches the B3 position, the fifth finger pattern 150 and the sixth finger pattern 160 do not occupy the cross section of the object. Also, the first and second fan-shaped patterns 170 and 180 similarly occupy the cross-sections F of the objects. Therefore, the capacitance changes occurring in the first and second fan-shaped patterns 170 and 180 due to the touch of the object are similar to each other. Therefore, the detection unit (not shown) can detect the change in capacitance of the first and second fan-shaped patterns 170 and 180 by touching the object, thereby determining the position of the object.

According to the present embodiment, the touch input by the object is detected by using the patterns of the quadratic quadrangle and the patterns of the quadratic quadrangle having a large variation of the pattern width according to the length of the pattern, Can be accurately detected with a higher sensitivity.

The third pattern 230 includes a plurality of fingers 230a, 230b and 230c extending in a first direction and the fingers of the third pattern 230 are interleaved with the B fingers of the first pattern. The B fingers 212a, 212b and 212c of the first pattern 210 and the fingers 230a, 230b and 230c of the third pattern form a quadrangle loop 217. A partial annular shape 215 formed by the first pattern 210 and the second pattern 220 and a partial annular shape 217 formed by the first pattern 210 and the third pattern 230 form a semi- It accomplishes.

Hereinafter, a method of detecting a touch of an object using the touch panel according to the present embodiment will be described with reference to the accompanying drawings. 5 is a view for explaining a method of locating an object with a touch panel according to the present embodiment when an object providing a touch input moves in a circumferential direction along an arrow. Referring to FIG. 5, when the object is at the X1 position, the first pattern 210 and the third pattern 230 occupy most of the cross section F of the object. The ratio of the area occupied by the third pattern 230 to the area occupied by the first pattern 210 is larger than the ratio of the area occupied by the first pattern 210 among the object cross-sections F. Therefore, The capacitance change amount is larger than the capacitance change amount of the first pattern 210. Accordingly, the detection unit (not shown) for detecting the touch of the object can detect the capacitance change amount of the first pattern 210 and the third pattern 230 to grasp the current position of the object.

As the object moves along the arrow direction, the area ratio of the third pattern 230 occupying the cross section F of the object decreases, and the area ratio of the first pattern 210 occupying the object section F increases. Accordingly, the amount of capacitance change of the third pattern 230 decreases, and the amount of capacitance change of the first pattern 210 increases.

When the object reaches the X2 position, the first pattern 210 occupies most of the object section F while the second pattern 220 and the third pattern 230 occupy the object section F at a similar ratio to each other do. Therefore, capacitance variation occurring in the first pattern 210 is largest when a touch is made by the object, and capacitance variation is similar to each other in the second pattern 220 and the third pattern 230. The detection unit (not shown) can detect that the object is in X2 by using the amount of capacitance change in each pattern.

As the object moves along the arrow direction, the third pattern 230 does not occupy the cross-section F of the object, and the first pattern 210 and the second pattern 220 occupy the cross-section F of the object The area ratio of the second pattern 220 occupying the cross section F of the object is increased as compared with the first pattern 210 as the object moves to the X3 position along the arrow direction. Therefore, the detecting unit can detect the capacitance change and detect that the object is moving along the arrow.

The second pattern 220 occupies most of the object section F when the object reaches the X3 position. Accordingly, when the object touches, the amount of capacitance change of the second pattern 220 is larger than the amount of capacitance change of the first pattern 210. The detection unit (not shown) can detect the position of the object by calculating the ratio of the capacitance variation of the first pattern 210 to the capacitance variation of the second pattern 220.

6 is a view for explaining a method of locating an object with a touch panel according to the present embodiment when an object providing a touch input is moved from the periphery to the center along the arrow. Referring to FIG. 6, when the object is at the Y1 position, the cross section of the object occupies a similar ratio between the first pattern 210 and the third pattern 230. Accordingly, when a touch is made by the object, the increase in capacitance is detected to the same degree in the first pattern 210 and the third pattern 230 of the detection unit (not shown). Accordingly, the object can detect the position of the object by detecting the amount of capacitance increase in the first pattern 210 and the third pattern 230.

The ratio of the first pattern 210 and the third pattern 230 occupying the object section gradually decreases as the object moves in the center direction along the arrow and the fourth pattern 240 and the sixth pattern 260 occupy The ratio gradually increases. When the object reaches the Y2 position, the cross section of the object occupies the fourth pattern 240 and the sixth pattern 260 in a similar ratio. Accordingly, when the object touches Y2, the detecting unit (not shown) can detect the position of the object by calculating the ratio of the amount of capacitance change of the fourth pattern 240 to the amount of capacitance change of the sixth pattern 260. [

The ratio of the fourth pattern 240 and the sixth pattern 260 occupying the object section gradually decreases as the object moves toward the center in the direction of the arrow and the ratio between the first and second fan patterns 270 and 280 ) Occupies a cross section of the object gradually increases. When the object reaches the Y3 position, the cross section of the object occupies a similar ratio of the first fan pattern 270 and the second fan pattern 280. [ Accordingly, when the object is touched, the amount of capacitance increase in the first and second fan-shaped patterns 270 and 280 is constant. The detection unit (not shown) can detect the position of the object using the capacitance increase amount in the first and second fan-shaped patterns 270 and 290.

According to this embodiment, a touch on the semicircular area can be detected using a total of eight patterns of two fan-shaped patterns and first through sixth patterns. Therefore, the number of wirings to be connected to each pattern can be reduced. Furthermore, it is possible to reduce the area where a touch-sensitive pattern can not be formed in order to form a wiring, thereby reducing the area of a portion where the touch can not be detected in the circular panel.

According to the present embodiment, unlike the prior art, since the touch on the periphery of the circular panel is detected by using a plurality of patterns forming a partial circle of an octree circle, a quadrant circle or a semicircle, the area of the portion where the touch can not be detected is reduced The advantage is provided.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of illustration, It will be appreciated that other embodiments are possible. Accordingly, the true scope of the present invention should be determined by the appended claims.
