BACKGROUND

Field of the invention

The present invention relates to a touch sensor and drive method, and more particularly to a dual mode touch-sensitive device and its operation.

Description of the article concerned

With the development of display technology, more and more novel displays are being used in many types of portable devices such as a notebook, a cell phone, a digital camera, and other electronic products. To make these portable devices not too heavy, the input devices have been changed from keyboards to touch panels.

Typically, three key sensory control technologies are used in the touch panels, such as resistive sensory technology, electromagnetic sensory technology, and capacitive sensory technology. In the capacitive touch-sensitive technology, only one side of the insulator is coated with a conductive layer. A low voltage is applied to the layer, resulting in a uniform electrostatic field. If a conductive medium, such as a human finger, touches the uncoated surface, capacitive resistance is dynamically generated. The control of the sensor may determine the location of the touch indirectly from the change in capacitance measured at the four corners of the display.

On the other hand, a sensor panel having the electromagnetic touch-sensitive technology includes a substrate having an antenna array, a position calculating control circuit and a touch pen. The touch pen is a transceiver and the substrate with the antenna array is a receiver. When a user uses the touch pen to touch the electronic paper display, the magnetic flux is changed. A microcontroller can detect the change in magnetic flux density to calculate the touch.

In general, a touch panel with the capacitive touch-sensitive technology has advantages such as waterproofness, scratch resistance and a high rate of transmission. In addition, it is also very convenient for the user to use the fingers to operate the display. However, if a selection point on the touch display is smaller than the size of the human finger, it is quite possible that another selection point will trigger an undesired function while the user is using his finger to select a function.

shows a schematic representation of an electrode structure of a touch-sensitive sensor. The electrode structure of the touch-sensitive sensor 100 The present invention is made on a base plate. The electrode structure includes a plurality of first leads 1011 ~ 101m arranged in a first direction, such as the Y direction and a plurality of first leads 1021 ~ 102n arranged in a second direction, such as the X direction. The first connecting cables 1011 ~ 101m cross the second connecting lines 1021 ~ 102n , The first connecting cables 1011 ~ 101m , and the second connecting cables 1021 ~ 102n are formed in different layers and are separated by an insulating layer over the base plate. In one embodiment, the first direction and the second direction include an angle of 90 degrees. However, in another embodiment, the first direction, and the second direction angles such. 60 degrees, 45 degrees, 36 degrees or 30 degrees. The material used for the first connecting cables 1011 ~ 101m , and second connection lines 1021 ~ 102n is metal, mischmetal, carbon nanotubes, transparent glue material such. Eg ITO, IZO.

One side of the first connecting cables 1021 ~ 101m is connected to a first select line G1 and a first transmission line L1. The first selection line G1 sends selection signals to some of the first connection lines 1011 ~ 101m be connected to the first transmission line L1 to produce a sensory technology, such as a capacitive sensory technology. In one embodiment, the first leads are 1011 ~ 101m with the first selection line G1 and with the first transmission line L1 through the switches 1231 ~ 123m connected. In one embodiment, the switches are 1231 ~ 123m Thin-film transistors (TFT). The gate electrodes of the switches 1231 ~ 123m are connected to the first selection line G1. If a square select signal is transmitted to the first select line G1, the switches become 1231 ~ 123m that receive the rectangle select signal turned on to the first leads 1011 ~ 101m to connect to the first transmission line L1. Then can the sensor 105 send a scanning signal to the first transmission line L1 to carry out a capacitive sensory technology. In another embodiment, the above electrode structure and scanning method can also be used in a resistance-sensitive scanning technology, a pressure-sensitive scanning technology or an optical-sensitive scanning technology.

On the other hand, one side is the second connecting cables 1021 ~ 102n connected to a first select line G1 'and a first transmission line L1'. The first select line G1 'sends select signals to some of the second lines 1021 ~ 102n be connected to the first transmission line L1 'to produce a sensory technology, such as a capacitive sensory technology. In one embodiment, the second leads are 1021 ~ 102n with the first selection line G1 'or with the first transmission line L1' through the switches 1531 ~ 153n connected. In one embodiment, the switches are 1531 ~ 153n Thin-film transistors (TFT). The gate electrodes of the switches 1531 ~ 153n are connected to the first selection line G1 '. If a square select signal is transmitted to the first select line G1 ', the switches become 1531 ~ 153n that receive the rectangle select signal turned on to the the first leads 1021 ~ 102n to be connected to the first transmission line L1 '. Then the sensor can 105 send a scanning signal to the first transmission line L1 'to perform a capacitive sensory technology. In another embodiment, the above electrode structure and scanning method can also be used in a resistance-sensitive scanning technology, a pressure-sensitive scanning technology or an optical-sensitive scanning technology.

In one embodiment, the sensor 105 support electromagnetic sensory technology, capacitive sensory technology, resistance-sensitive sensory technology, pressure-sensitive sensory technology, or optically-sensitive sensory technology to calculate position and height. In one embodiment, the sensor transmits 105 an exciting signal or a sample signal to the signal in some of the first leads 1011 ~ 101m detected by the first selection line G1, and transmits an exciting signal or a sampling signal to the signal in some of the second connection lines 1021 ~ 102n to perceive that has been selected by the first selection line G1 '.

There are usually two types of capacitive touch-sensitive technology. One is the sensory technology through self-sufficiency. The other is sensory technology through mutual capacity. Therefore, if a capacitive sensory technology by the scanning sensor 100 according to the sensory technology is carried out by self-capacitance, the sensor decreases 105 the capacity is generated between the first connecting lines 1011 ~ 101m and the floor and between the second connecting lines 1021 ~ 102n and the ground to determine the scanning position. Therefore, when a user's finger touches a position, charges that are in that position become out of the first leads 1011 ~ 101m or second connection lines 1021 ~ 102n , transferred to the user's finger, which changes the capacity in this position. In this case, the sensor can 105 feel this change in capacity in this position to determine the position. Accordingly, if the sensory technology is performed by self-capacitance, the sensor sends 105 a selection signal to the first selection lines G1 and G1 ', so that the first connecting lines 1011 - 101m and the second connection lines 1021 ~ 102n be connected to the first transmission lines L1 and L1 '. Then that's from the sensor 105 sent signal to the first connection lines 1011 ~ 101m , and the second connecting cables 1021 ~ 102n transmitted via the first transmission lines L1 and L1 'to determine the position of the capacitance changes. Then the sensor can 105 calculate the touch position due to the capacitance changes.

On the other hand, after the touch-sensitive technology by mutual capacity, the sensor senses 105 the capacity is generated between the first connecting lines 1011 ~ 101m , and the second connecting cables 1021 - 102n to determine the touch position. And so are the first leads 1011 ~ 101m , and the second connecting cables 1021 ~ 102n the two electrodes of the capacitor. Therefore, when a user's finger touches a position, charges that are in that position become out of the first leads 1011 ~ 101m or second connection lines 1021 ~ 102n , transferred to the user's finger, which changes the capacity in this position. In this case, the sensor can 105 feel this change in capacity in this position to determine the position. Accordingly, if the sensory technology is performed by mutual capacity for detecting the touch position, the sensor sends 105 a scanning signal to the first connecting lines 1011 ~ 101m through the first transmission line L1 and receives a sampling signal from the second connection lines 1021 ~ 102n through the first transmission line L1 'to determine the positions of the capacitance changes. Or sends the sensor 105 a scanning signal to the second connecting lines 1011 ~ 102n through the first transmission line L1 'and receives a sampling signal from the first connection lines 1021 ~ 101m through the first transmission line L1 to determine the positions of the capacitance changes. Then the sensor can 105 calculate the touch position due to the capacitance changes. It has been found that the scanning method can also be used in resistive-sensitive scanning technology, pressure-sensitive scanning technology or optically-sensitive scanning technology.

The sensor 105 provides an exciting signal or a sample signal to the signal in some of the first leads 1011 ~ 101m detected by the second selection line G2 and the third selection line G3, and transmits an exciting signal or a sampling signal to the signal in some of the second connection lines 1021 ~ 102n to perceive that have been selected by the second selection line G2 'and the third selection line G3'.

FIG. 12 is a schematic illustration of a control signal of an electromagnetic touch-sensitive sensor technology used to perform Y-direction scanning in accordance with a preferred embodiment of the present invention. FIG. In this embodiment, the sensor sends 105 a first signal 201 to the first select line G1 to all switches 1231 ~ 123m turn. In one embodiment, if the switches 1231 ~ 123m N type switches are thin-film transistors, is the first control signal 201 in a high status. On the other hand, if the switches 1231 ~ 123m P type switch are thin-film transistors is the first control signal 201 is in a low status. In this embodiment, the switches are 1231 ~ 123m N type switch thin-film transistors. This is the first control signal 201 in a high status. If all switches 1231 ~ 123m are turned on, the first connection lines 1011 ~ 101m with the first transmission line L1 through the switches 1231 ~ 123m connected.

On the other hand, the sensor sends 105 a second signal 202 to the second select line G2 to the switches 1331 ~ 133m turn. In one embodiment, the second control signal is 202 a square wave signal. The square-wave signal has a time width W1. The time width W1 is the same as the time period during which some of the first connection lines 1011 ~ 101m be scanned at the same time. For example, according to one embodiment, scanning of all first leads requires 1011 ~ 101m a T time period. Accordingly, the scanning of each first connection line needs 1011 ~ 101m a T / m time period. In other words, the time period K · T / m when the number K of the first connection lines 1011 ~ 101m be scanned at the same time. Here, the time width W1 can be defined by the following equation. T / m × ≦ W1 <× T / m (z + 1)

Z is the number of first connection lines 1011 ~ 101m scanned at the same time. so if Z is the number of first leads 1011 ~ 101m is to be scanned simultaneously, the time width W1 must be less than (Z + 1) * T / m in order to prevent an additional first connection line from being added.

Accordingly, if the second rectangle type control signal 202 is transmitted to the second selection line G2, the switches 1331 ~ 133m which is the second control signal 202 received, turned on to some of the first connection lines 1011 ~ 101m to the second transmission line L2 through the switched-on switches 1331 ~ 133m connect to. Because the switches 1331 ~ 133m by the second control signal 202 are sequentially turned on, and since the time width W1 is set to be greater than (Z · T / m) and less than (Z + 1) · T / m, that is, the Z number of simultaneously scanned first leads 1011 ~ 101m , be the first connecting cables 1011 ~ 101m divided into a plurality of groups to be connected to the second transmission line L2. Each group has z number of first connection lines 1011 ~ 101m ,

On the other hand, becomes a third control signal 203 to the third selection line G3 through the sensor 105 after a t time period after the second control signal 202 sent to the second selection line G2. The t time period is related to the number of first connection lines 1011 ~ 101m surrounded by a loop. For example, if a loop 30 first connection lines 1011 ~ 101m t is equal to (T / m x 30) time period. That is, a third control signal 203 to the third selection line G3 through the sensor 105 after a (T / m × 30) period of time after the second control signal 202 is sent to the second selection line G2.

The third control signal 203 is a square wave signal. The square wave signal has a time width W2. The time width W2 is the same as the time period during which some of the first connection lines 1011 ~ 101m be scanned at the same time. For example, according to one embodiment, scanning of all first leads requires 1011 ~ 101m a T time period. Accordingly, the scanning of each first connection line needs 1011 ~ 101m a T / m time period. In other words, the time period is K · T / m when the number K of the first connection lines 1011 ~ 101m be scanned at the same time. Here, the time width W2 can be defined by the following equation. T / m × ≦ W2 <× T / m (z + 1)

Z is the number of first connection lines 1011 ~ 101m scanned at the same time. so if Z is the number of first leads 1011 ~ 101m is to be scanned simultaneously, the time width W2 must be less than (Z + 1) * T / m to prevent an additional first connection line from being added.

Accordingly, if the second rectangle type control signal 203 is transmitted to the second selection line G3, the switches 1431 ~ 143m which is the second control signal 203 received, turned on to some of the first connection lines 1011 ~ 101m with the second transmission line L3 through the switched switch 1431 ~ 143m connect to. Because the switches 1431 ~ 143m by the second control signal 203 are set sequentially, and since the time width W2 is set to be greater than (Z · T / m) and less than (Z + 1) · T / m, that is, the Z number of simultaneously scanned first leads 1011 ~ 101m , be the first connecting cables 1011 ~ 101m divided into a plurality of groups to be connected to the second transmission line L3. Each group has z number of first connection lines 1011 ~ 101m ,

It should be noted that in another embodiment, the time width W1 is not identical to the time width W2. Because the sensor 105 the second control signal 202 and the third control signal 203 , which have different time widths, can send to the second selection line G2 and to the third selection line G3, respectively. Therefore, the number of first connection lines 1011 ~ 101m connected to the second transmission line L2 different from the number of first connection lines 1011 ~ 101m which are connected to the third transmission line L3.

thus, if an electromagnetic touch sensing sensor technology is performed to sense a loop surrounding two first leads, the sensor transmits 105 a first control signal 201 to the first select line G1 to all switches 1231 ~ 123m turn. If all switches 1231 ~ 123m are turned on, the first connection lines 1011 ~ 101m with the first transmission line L1 through the switches 1231 ~ 123m connected. Next, the sensor will send 105 a second control signal 202 to the second select line G2 to the switches 1331 ~ 133m turn on so that the first leads 1011 ~ 101m be connected to the second transmission line L2. In this embodiment, two switches each time are the switches 1331 ~ 133m together with the second control signal 202 is turned on to connect two first connection lines to the second transmission line L2 simultaneously. The sensor 105 also sends a second control signal 203 to the third select line G3 to the switches 1431 ~ 143m turn on so that the first leads 1011 ~ 101m be connected to the third transmission line L3. In this embodiment, two switches each time are the switches 1431 ~ 143m together with the second control signal 203 is turned on to connect two first leads to the third transmission line L3 simultaneously.

In this embodiment, two first connection lines are connected to the second transmission line L2 and the third transmission line L3 at the same time. Therefore, the time width W of the second control signal 202 and the third control signal 203 be defined by the following equation. T / m × 2 ≦ W <T / m × 3

Moreover, in this embodiment, each loop surrounds two first leads. That is, a third control signal 203 to the third selection line G3 through the sensor 105 after a (T / m × 30) period of time after the second control signal 202 is sent to the second selection line G2.

In one embodiment, a loop is made 107 educated. The N-type switches 1331 and 1332 are by the second control signal 202 switched on at a high level. Then the first connecting cables 1011 and 1012 with the second transmission line L2 through the switches 1331 and 1332 connected. The N-type switches 1435 and 1436 be by the third control signal 203 switched on at a high level. Then the first connecting cables 1015 and 1016 with the third transmission line L3 through the switches 1435 and 1436 connected. The bow 107 surrounds two first connection lines 1013 and 1014 , Then the sensor sends 105 a scanning signal to the first connecting lines 1011 and 1012 through the second transmission line L2 and receives a sampling signal from the first connection lines 1015 and 1016 through the third transmission line L3 to determine if the sample signal is in the loop 107 was changed. In one embodiment, the sensor 105 determine if the magnetic flux, electromagnetic induction, current, or frequency changed according to the sampling signal. In one embodiment, the sampling signal is a rectangular signal, a triangular signal, a triangle-like signal, or a wave signal consisting of a plurality of square-wave signals. The change of the sampling signal includes the distortion of the wave, the change of the average value of the signal, the change of the maximum value of the signal, the change of the current or the change of the voltage.

In addition, the second control signal 202 sent to the second select line G2 a square wave signal. The third control signal 203 sent to the third select line G3 is a square wave signal. Therefore, the loops are sequentially formed the second control signal 202 and the third control signal 203 corresponding. The loops may overlap one another to prevent a "sample gap" case. For example, a loop A and a loop B are formed one after the other. Sensory loop A and loop B overlap to prevent a "sample gap" case. Accordingly, the loops are formed by the use of the first control signal 201 , the second control signal 202 and the third control signal 203 for the control of the first connection lines 1011 ~ 101m to connect the first transmission line L1, the second transmission line L2, and the third transmission line L3. The first control signal 201 the second control signal 202 and the third control signal 203 can be made by a software. It is therefore not necessary to add extra hardware to the display Add. This reduces production costs.

The above method can also be used on the second connecting cables 1021 ~ 102n be used to detect the touch point. FIG. 12 is a schematic illustration of a control signal of an electromagnetic touch-sensitive sensor technology used to perform X-direction scanning according to a preferred embodiment of the present invention. The sensor 105 sends a first signal 301 to the first select line G1 'to all switches 1531 ~ 153n turn. If all switches 1531 ~ 153n are turned on, the second connecting cables 1021 ~ 102n with the first transmission line L1 'through the switches 1531 ~ 153n connected. Next, the sensor will send 105 a second control signal 302 to the second select line G2 'to the switches 1631 ~ 163N turn on so that the second leads 1021 ~ 102n be connected to the second transmission line L2. In this embodiment, the switches 1631 ~ 163N by the second control signal 302 switched on one after the other to the second connecting cables 1021 ~ 102n to connect to the second transmission line L2 '. The sensor 105 also sends a third control signal 303 to the third selection line G3 'to the switches 1731 ~ 173n turn on so that the second leads 1021 ~ 102n be connected to the third transmission line L3 '. In this embodiment, the switches 1731 ~ 173n by the third control signal 303 switched on one after the other to the second connecting cables 1021 ~ 102n to be connected to the third transmission line L3 '.

In one embodiment, the second control signal is 302 a square wave signal. The square-wave signal has a time width W1 '. The time width W1 'is the same as the time period during which some of the second connection lines 1021 ~ 102n be scanned at the same time. For example, according to one embodiment, scanning of all second leads requires 1021 ~ 102n a T 'time period. Accordingly, the scanning of every other connection line 1011 ~ 102n takes a (T '/ n) time period. In other words, the time period is (K * T '/ n), where K is the number of second connection lines 1021 ~ 102n being scanned simultaneously. so, the time width W1 'can be defined by the following equation. T / n × z ≦ W1 '<T / n × (z + 1)

Z is the number of second connection lines 1021 ~ 102n scanned at the same time.

Similar is the third control signal 303 a square wave signal. The square-wave signal has a time width W2 '. The time width W2 'is the same as the time period during which some of the second connection lines 1021 ~ 102n be scanned at the same time. For example, according to one embodiment, scanning of all second leads requires 1021 ~ 102n a T 'time period. Accordingly, the scanning of every second connection line needs 1011 ~ 102n a (T '/ n) time period. In other words, the time period is (K * T '/ n), where K is the number of second connection lines 1021 ~ 102n is scanned at the same time. so, the time width W2 'can be defined by the following equation. T / n × z ≦ W2 '<T / n × (z + 1)

Z is the number of second connection lines 1021 ~ 102n scanned at the same time.

On the other hand, becomes a third control signal 303 to the third selection line G3 'through the sensor 105 after a t time period after the second control signal 302 sent to the second selection line G2 '. The t time period is related to the number of second connection lines 1021 ~ 102n surrounded by a loop. For example, if a loop 30 second connecting cables 1021 ~ 102n t is equal to (T / n x 30) time period. That is, the third control signal 303 to the third selection line G3 'through the sensor 105 after a (T / n * 30) period of time after the second control signal 302 is sent to the second selection line G2 '. By controlling the second control signal 302 and the third control signal 303 be loops in the second leads 1021 ~ 102n formed one after the other. Therefore, an electromagnetic touch-sensitive sensor technology is performed to detect loops for the determination of the touch position.

In one embodiment, a loop is made 108 educated. The N-type switches 1631 and 1632 are by the second control signal 302 switched on at a high level. Then the second connecting cables 1021 and 1022 with the second transmission line L2 'through the switches 1631 and 1632 connected. The N-type switches 1635 and 1636 be by the third control signal 303 switched on at a high level. Then the second connecting cables 1025 and 1026 with the third transmission line L3 'through the switches 1635 and 1636 connected. The bow 108 surrounds two second connection lines 1023 and 1024 , Then the sensor sends 105 a scanning signal to the second connecting lines 1021 and 1022 through the second transmission line L2 'and receives a sampling signal from the second connection lines 1025 and 1026 through the third transmission line L3 'to determine whether the sampling signal in the loop 108 was changed. In one embodiment, the sensor 105 determine if the magnetic flux, electromagnetic induction, current, or frequency changed according to the sampling signal. In one embodiment, the sampling signal is a rectangular signal, a triangular signal, a triangle-like signal, or a wave signal consisting of a plurality of square-wave signals. The change of the sampling signal includes the distortion of the wave, the change of the average value of the signal, the change of the maximum value of the signal, the change of the current or the change of the voltage.

For example, if a user has a pen 112 with a magnetic scanning loop or an LC loop used to position 111 To touch, the magnetic flux, the electromagnetic induction, the current or the frequency of the loop 107 and loop 108 changed. Such a change alters the sample signal in the loops 107 and 108 , If the sensor 105 If this change in the scanning signal is felt, the sensor can determine that the position 111 in the overlap area between the loops 107 and 108 , the user's touch position.

On the other hand, if the capacitive touch-sensitive sensor technology through the dual-mode scanning sensor 101 is performed, the sensor sends 105 a first control signal to the first select line G1 to the connection between the first connection lines 1011 ~ 101m and the first transmission line L1. The sensor 105 Also sends a first control signal to the first selection line G1 ', so that the second connecting lines 1021 ~ 102n be separated from the first transmission line L1 '. There are usually two types of capacitive touch-sensitive technology. One is the sensory technology through self-sufficiency. The other is sensory technology through mutual capacity.

According to the sensory technology by self-capacitance, the sensor decreases 105 the capacity is generated between the first connecting lines 1011 ~ 101m and the floor and between the second connecting lines 1021 ~ 102n and the ground to determine the touch position. Therefore, when a user's finger touches a position, charges that are in that position become out of the first leads 1011 ~ 101m or second connection lines 1021 ~ 102n , transferred to the user's finger, which changes the capacity in this position. In this case, the sensor can 105 feel this change in capacity in this position to determine the position. Accordingly, if the touch-sensitive sensor technology is performed by self-capacitance, the sensor sends 105 a second control signal to the second selection line G2 to the connection between the first connecting lines 1011 ~ 101m and the first transmission line L2. The sensor 105 Also sends a second control signal to the second selection line G2 ', so that the second connecting lines 1021 ~ 102n be separated from the second transmission line L2 '. Then the sensor sends 105 a third control signal to the third selection line G3, to some of the first connection lines 1011 ~ 101m to be connected to the third transmission line L3. The sensor 105 also sends a third control signal to the third selection line G3 ', to some of the second connection lines 1021 ~ 102n to be connected to the third transmission line L3 '. The sensor 105 sends a control signal to the selected first connection lines through the third transmission line L3. The sensor 105 sends a control signal to the selected second connection lines through the third transmission line L3 '. Then the sensor can 105 calculate the touch position due to the capacitance changes.

On the other hand, after the touch-sensitive technology by mutual capacity, the sensor senses 105 the capacity is generated between the first connecting lines 1011 ~ 101m , and the second connecting cables 1021 ~ 102n to determine the touch position. And so the first connection line and the second connection line are the two electrodes of a capacitor. Therefore, when a user's finger touches a position, charges that are in that position become out of the first leads 1011 ~ 101m or second connection lines 1021 ~ 102n , transferred to the user's finger, which changes the capacity in this position. In this case, the sensor can 105 feel this change in capacity in this position to determine the position. Accordingly, if the sensory technology is performed by mutual capacity for detecting the touch position, the sensor sends 105 a scanning signal to the first connecting lines 1011 ~ 101m through the second transmission line L2 and receives a scanning signal from the second connecting lines 1021 ~ 102n through the second transmission line L2 'to determine the positions of the capacitance changes. Or sends the sensor 105 a scanning signal to the second connecting lines 1011 ~ 102n through the second transmission line L3 'and receives the sampling signal from the first connection lines 1021 ~ 101m through the second transmission line L2 to determine the positions of the capacitance changes. Then the sensor can 105 calculate the touch position due to the capacitance changes. It has been found that the scanning method also in a resistance-sensitive scanning technology, a pressure-sensitive scanning technology or a optically-sensitive scanning technology can be used.

Accordingly, the dual mode offers touch sensor 100 In the present invention, two types of sensory technologies, the electromagnetic sensory technology and the capacitive sensory technology, are used to determine the touch position. In electromagnetic sensory technology, can. the user is using a stylus with a magnetic scanning loop or an LC loop for writing. In capacitive sensory technology, the user can use his finger for writing. That is, the present invention provides various input interfaces to the user for better comfort. When a user touches an ad, he enters the dual-mode sensor 100 According to the present invention, both the electromagnetic sensory technology and the capacitive sensory technology are used to determine the touch position, which increases the detection accuracy. In another embodiment, a user may select one of the two types of sensory technologies, the electromagnetic sensory technology and the capacitive sensory technology to determine the touch position. When both the electromagnetic sensory technology and the capacitive sensory technology are used for the determination of the touch position, in one embodiment the electromagnetic sensory technology, then the capacitive sensory technology is used for the determination of the touch position, or in another embodiment the capacitive sensory technology then used the electromagnetic sensory technology for determining the touch position.

Moreover, in order to prevent the switches from losing their operability due to frequent switching, two selector lines G1 and G2 are used to control two switches so that connection between the first leads or the second leads and the transmission line L as in FIG is produced represented. Corresponding to such a structure, even if one of the two switches breaks down, the other switch can also establish the connection between the first connecting lines or the second connecting lines and the transmission line L. In another embodiment, the switches may have a dual output structure.

On the other hand, the electrode structure of a double-mode touch sensor according to a preferred embodiment of the present invention can be integrated into the region electrode of a display. Thus, the region electrode of a display can be used to serve as the electrode for the dual-mode touch sensor of the present invention.

The FIG. 12 shows a display matrix electrode structure of a display used to serve as a scanning electrode structure of a dual mode touch-sensitive sensor according to a preferred embodiment of the present invention. The display consists of a plurality of data lines DA1, DA2 ... DAm and a plurality of scan lines GA1, GA2, ..., GAn. The data lines cross the scan lines. Each pair of data lines and scan lines controls one pixel unit. For example, the data line DA1 and the scan line GA1 control one pixel. The gate driver 401 sends a scan signal to the scan lines GA1, GA2, ..., GAn. The scan signal in the scan line can turn on the corresponding thin film transistor. Then, the source driver transmits the image signal to the pixels through the data lines DA1, DA2, ... DAm to display the image. It is therefore not necessary to create additional electrodes for the determination of the contact position. Therefore, the production costs are reduced, and the production yield is increased.

In this embodiment, the data lines DA1, DA2... DAm are the first connection lines 1011 ~ 101m , The scan lines GA1, GA2, ..., GAn are the first connection lines 1021 ~ 102n , The sensor 403 is in the gate driver 401 integrated to sense the Y direction. The sensor 404 is in the gate driver 405 integrated to feel the X direction. Accordingly, the sensor sends 404 a first control signal to the first select line G1 to all switches 1231 ~ 123n turn. In this embodiment, the switches are 1231 ~ 123m N type switch thin-film transistors. So the first control signal is in a high level status. If all switches 1231 ~ 123m are turned on, the data lines DA1, DA2 ... DAm with the first transmission line L1 through the switches 1231 ~ 123m connected. Next, the sensor will send 404 a second control signal to the second select line G2 to the switches 1331 ~ 133m to turn on, so that the data lines DA1, DA2 ... DAm are connected to the second transmission line L2. The sensor 404 Also sends a third control signal to the third select line G3 to the switches 1431 ~ 143m to turn on, so that the data lines DA1, DA2 ... DAm are connected to the third transmission line L3.

On the other side, the sensor sends 403 a first signal to the first select line G1 to all switches 1531 ~ 153n turn. If all switches 1531 ~ 153n are turned on, the scan lines GA1, GA2, ..., GAn are connected to the first transmission line L1 'through the switches 1531 ~ 153n connected. Next, the sensor will send 403 a second control signal to the second select line G2 'to the switches 1631 ~ 163N to connect the scan lines GA1, GA2, ..., GAn to the second transmission line L2 '. The sensor 403 Also sends a third control signal to the third select line G3 'to the switches 1731 ~ 173n to connect the scan lines GA1, GA2, ..., GAn to the third transmission line L3 '. The method such as the electromagnetic sensor technology and the capacitive sensor technology in this embodiment is carried out is the same as the above-mentioned embodiment.

In one embodiment, the switches are thin-film transistors (TFT) or other devices having the same function as the thin-film transistors. If the switches are thin-film transistors, the switches can be formed on the array baseplate. In another embodiment, one or two of the three switch groups, the switches 1231 ~ 123m , the switches 1331 ~ 133m and the switches 1431 ~ 143m , in the source driver 402 to get integrated. One or two of the three switch groups, the switches 1531 ~ 153n , the switches 1631 ~ 163N and the switches 1731 ~ 173n , can in the gate driver 401 to get integrated. Like in the shown are the switches 1231 ~ 123m in the source driver 402 integrated. The switches 1531 ~ 153n are in the gate driver 401 integrated.

In addition, the display is an organic light display, a thin-film liquid crystal display with a thin film transistor, an electrode display or an electrophoretic display. The pixel array in this display is a transmissive-mode pixel array, a reflective-mode pixel array, or a double-mode transflective pixel array.

The Figure 4 shows a flowchart for the description of how the electromagnetic touch-sensitive sensor technology and then how the capacitive touch-sensitive sensor technology is performed to determine the touch position. Please see the and ,

In step 501 , a control signal controls one end of each first lead to be connected to a first transmission line. Another control signal selects the first leads sequentially to connect to the second and third loop-forming transmission lines. For example, the sensor sends 105 a first control signal to the first select line G1 to all switches 1231 ~ 123m turn. If all switches 1231 ~ 123m are turned on, the first connection lines 1011 ~ 101m with the first transmission line L1 through the switches 1231 ~ 123m connected. On the other side, the sensor sends 105 a second control signal to the second select line G2 to the switches 1331 ~ 133m turn on so that the first leads 1011 ~ 101m be sequentially connected to the second transmission line L2. The sensor 105 Also sends a third control signal to the second select line G2 to the switches 1431 ~ 143m turn on so that the first leads 1011 ~ 101m be connected to the third transmission line L3. The loops are formed in the first connection lines.

In the next step 503a , the sensor checks the magnetic flux, the electromagnetic induction, the current or the frequency of the loops to determine the touch position.

In step 502 , a control signal controls one end of each second connection line to be connected to a first transmission line. Another control signal selects the second leads sequentially to connect to the second and third loop-forming transmission lines. For example, the sensor sends 105 a first control signal to the first select line G1 'to all switches 1531 ~ 153n turn. If all switches 1531 ~ 153n are turned on, the second connecting cables 1021 ~ 102n with the first transmission line L1 'through the switches 1531 ~ 153n connected. On the other side, the sensor sends 105 a second control signal to the second select line G2 'to the switches 1631 ~ 163N turn on so that the second leads 1021 ~ 102n be sequentially connected to the second transmission line L2 '. The sensor 105 Also sends a third control signal to the second select line G2 'to the switches 1731 ~ 173n turn on so that the second leads 1021 ~ 102n be sequentially connected to the third transmission line L3. The loops are formed in the second connecting lines.

In the next step 503b , the sensor checks the magnetic flux, the electromagnetic induction, the current or the frequency of the loops to determine the touch position. For example, the sensor sends 105 a control signal to the first connecting lines 1011 ~ 101m through the second transmission line L2 and receives the sensory signal from the third transmission line L3. The sensor 105 also sends a sensory signal to the second leads 1021 ~ 102n through the second transmission line L2 'and receives the sensory signal from the third transmission line L3'. Accordingly, can a touch position can be determined. In one embodiment, the sensor 105 determine if the magnetic flux, electromagnetic induction, current, or frequency changed according to the sampling signal. In one embodiment, the sampling signal is a rectangular signal, a triangular signal, a triangle-like signal, or a wave signal consisting of a plurality of square-wave signals.

Thereafter, a capacitive sensory technology is performed. In step 504 , the sensor separates the connection between the first connecting lines and disconnects the connection between the second connecting lines.

In step 505 , the sensor determines the touch position due to the capacitance changes. There are usually two types of capacitive touch-sensitive technology. One is the sensory technology through self-sufficiency. The other is sensory technology through mutual capacity. According to the sensory technology by self-capacitance, the sensor can 105 feel this change in capacity in this position to determine the position. Accordingly, if the touch-sensitive sensor technology is performed by self-capacitance, the sensor sends 105 a second control signal to the second selection line G2 to the connection between the first connecting lines 1011 ~ 101m and the first transmission line L2. The sensor 105 Also sends a second control signal to the second selection line G2 ', so that the second connecting lines 1021 ~ 102n be separated from the second transmission line L2 '.

The sensor 105 also sends a third control signal to the third selection line G3 ', to some of the second connection lines 1021 ~ 102n to be connected to the third transmission line L3 '. The sensor 105 sends a control signal to the selected first connection lines through the third transmission line L3. The sensor 105 sends a control signal to the selected second connection lines through the third transmission line L3 '. Then the sensor can 105 calculate the touch position due to the capacitance changes.

On the other hand, if the sensory technology is performed by mutual capacity for detecting the touch position, the sensor sends 105 a scanning signal to the first connecting lines 1011 ~ 101m through the second transmission line L2 and receives a scanning signal from the second connecting lines 1021 ~ 102n through the second transmission line L2 'to determine the positions of the capacitance changes. Or sends the sensor 105 a scanning signal to the second connecting lines 1011 ~ 102n through the second transmission line L3 'and receives the sampling signal from the first connection lines 1021 ~ 101m through the second transmission line L2 to determine the positions of the capacitance changes. Then the sensor can 105 calculate the touch position due to the capacitance changes.

The data field of the image collection device can collect images or gestures. In addition, the data field serving as a touch electrode structure may determine the position or height of the image or gesture to carry out another application or to establish a relationship or give an answer.

Accordingly, as compared with a conventional image collection apparatus and touch sensor, the image collection apparatus with a touch sensor of the present invention can support multiple applications. For example, according to the collected images or gestures and the corresponding detected positions of the collected images or gestures by the touch-sensitive image collection device, differently collected images or gestures may trigger different applications, regardless of the collected images or gestures having the same detected positions. In one embodiment, if the tracked position may trigger an application to play music or display pictures, a conventional touch sensor should perform an additional touch step to select whether to play music or display pictures after the application is triggered. However, according to the touch-sensitive image collection apparatus of the present invention, a user may use different gestures to directly trigger the application and play between music or show images, saving a selection step.
