200949640 IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a touch sensor device (deviee); and more particularly, to a touch sensing device, which processes The operation of the electrical signal generated by the touch input on the touch panel and performing various input signals; and an operation mode switching method in the touch sensor device. [Prior Art] ® As a data input device, a touch pad has touch points, and the touch points are arranged in a matrix on a plane for detecting the position touched by the user and the direction indicated by the touch point. And therefore widely used in place of the mouse. There are various touch panels, including an electrical switch arranged on a plane, a capacitive sensor sens〇〇 or a transistor-type sensor (transistor-type sensoiO. In these types, including multiple touches The touch panel of the board and using the capacitive sensor is often used to control the movement of the cursor in the notebook (n〇teb〇〇k © computer), etc. The surface of the touch panel is covered with an insulating layer and the vertical and horizontal lines Arranged at regular intervals below the insulating layer. The capacitor is placed between the horizontal and vertical lines as an electrical equivalent circuit (dectrical 'equivalent'), wherein the horizontal line constitutes the first electrode and the vertical line constitutes the second electrode. When the surface is touched, the capacitance between the horizontal line and the vertical line corresponding to the touch point is different from the capacitance between the other lines of the non-touch point. Therefore, the voltage signal can be applied to the horizontal line and read from the vertical line 5 200949640 Change the capacitance of the capacitor to detect the touch point. Input letter signals, digital signals, shape signals, etc. to the touch panel Therefore, the touch panel is very useful when inputting information frequently and when it is convenient. For example, the 'cellular phone' provides a hot number function to simplify the input of the phone number. It is shorter than the telephone number and thus facilitates the input of the telephone number. However, since it is difficult to give the hotline number a certain meaning, it is difficult to remember the hotline number and it is necessary to check each time. On the other hand, it is easy to make meanings related to letters, numbers and shapes. For example, when the user wants to enter a specific person's phone number, the user can enter the person's Korean name or the first consonant of the nickname, or the person's English The first letter of the name is used to make a call, which is very convenient to remember and use. Figure 1 is a block diagram of an electrical touch sensor device according to the prior art. The electric touch sensor device includes The touch panel 10, the touch sensor chip 20, and the microcontroller unit MM (Microcontroller Unit, MCU) 30. The panel 10 includes a plurality of touch sensors 10-1 to 10-N, and the touch sensor chip 20 includes a plurality of touch sensors 20-1 to 20-N. The touch electrodes 10-1 to 10-N arranged on the surface of the touch panel 10 inform the touch sensor wafer 20 whether the touch electrodes 10-1 to 10-N themselves are touched" in the touch sensor The touch sensors 20-1 to 20-N in the wafer 20 are electrically connected to the touch electrodes 10-1 to 10-N, and the 6 200949640 MCU 30 processes the signals obtained from the touch sensor chip 2, And the electrical touch sensor device is controlled to perform the operations represented by the letters, numbers or shape symbols. 2 is a flow chart illustrating the operation of an electrical touch sensor device in accordance with conventional techniques. This operation will be described below with reference to FIGS. 1 and 2. First, pattern signals such as letter signals, digital signals, and shape signals are input to the touch panel 10, and are mapped and stored in the MCU 3〇(sl〇) corresponding to the respective rounds to be in the active mode (active mode) The operation performed in ). When the electric touch sensor device in the sleep mode starts operating, the MCU 30 checks at regular intervals whether a human body touches the touch electrodes 1 (M to 1 〇_N). In other words, when the touch panel 1 is operated at regular intervals (S2〇), the touch sensors 2〇_i to 2〇_^ in the touch sensor wafer 20 are connected

The touch information from the electrically connected touch electrodes iOd to 1〇_N is received and the power signal is output (S30;). J Ο In the electrical signal output through the touch sensor chip 20, calculate the position, moving direction and moving path of the initial touch point and store the calculated value while the MCU 3G synthesizes the calculated value and walks in the touch state A piece of sense data (S35) is generated. The sensed data generated in this manner is compared to the previously mapped letters, numbers, and shape signals (S4G). When there is a sensing data sub-signal, the electric touch sensor device is switched to the awake mode m〇de) (S50), and the MCU 3〇 controls the electric touch sensor device,

200949640 The operation corresponding to the input signal (S55). When there is no signal identical to the sensing data, the electric touch sensor device is maintained in the sleep mode (S15), and the MCU 30 repeatedly checks whether the human body touches the touch electrodes to 1 〇_N. Wherein, the 4-touch sensor chip 2 does not sense that the human hand touches the touch panel 10, the 'MCU 30 disables the operation of the electric touch sensor device and cuts off the power supply. On the other hand, when the touch sensor chip 20 senses that the human hand touches the touch panel 1,, the operation of the power source is enabled and the operation power is supplied to the respective components of the electric touch sensor device. 0 When an electrical touch detector device is a wireless device, its operating time is limited by its power source (such as rechargeable batteries and batteries). Therefore, it is important to maximize the operating time. However, according to the prior art In the electric touch sensor device, the MCU 30 performs all of the following operations: · Calculating the position, moving direction and moving path of the initial touch point on the touch panel 10, generating sensing data, comparing the sensed data with the stored The letters, numbers and shape signals as well as the control of the electric touch sensor are performed in the promotion, thus consuming a lot of power. 'Moving mode at the same time, in order to sense the touch of the human hand on the touch surface in the inactive state, it must occasionally Enable the power supply to drive the touch sensing " 曰10 and MCU 30. Therefore, in order to increase the response speed, it is necessary to frequency '20 power supply, which leads to an increase in power secret. Therefore, in the case of the electric touch sensor according to the prior art, a mechanical switch is required for switching from the inactive state to the mold gas, which requires 200949640, in order to input different types of signals to only one touch panel ( That is, 'letter signal, digital signal, and shape signal' need to be switched from the corresponding input mode to the *awake mode from the operation mode switch. Therefore, the electric touch sensor device according to the prior art has complexity. The present invention is directed to providing a touch sensor device that can perform the following functions of a 0 micro control unit (MCU): a previously stored pattern signal, a self-touch panel The touch signal generates sensing data, and compares the stored pattern signal with the generated sensing data to control the operation mode without operating the mode switch.

The above and other objects, features, and advantages of the invention will be apparent from [Embodiment] Hereinafter, a semiconductor device and a daisy-chain-communication-mode touch sensor device according to an exemplary embodiment of the present invention are described in detail. However, the invention is not limited to the exemplary embodiments disclosed below, but may be embodied in various forms. The following exemplary embodiments are described to enable those skilled in the art to practice and practice the invention. 3 is a block diagram of an electrical touch sensor device having a touch panel 10 and a touch sensor wafer 100, in accordance with an exemplary embodiment of the present invention. The touch panel 10 includes a plurality of touch electrodes 1〇_1 to 1〇_Ν, and the touch sensor chip 100 includes a touch sensor unit 20, a data storage device 10, a sensing data generator 140, The comparator 170 and the touch position data generator 180. The touch sensor unit 20 includes a plurality of touch sensors 20-1 to 20-N. The function of the respective components of the electric touch sensor device according to an exemplary embodiment of the present invention will be described below with reference to FIG. In the touch panel 10, the touch electrodes 10-1 to 10-N are arranged in a matrix on a plane. The touch panel 10 receives input signals (such as alpha signals, digital signals, and shape signals) and generates electrical signals based on the internal capacitance change 200949640. The data storage device 110 is in the previously stored pattern signals (such as letter* signals, digital signals, and shape signals), and the pattern signals are input to the touch panel 10 to switch the electric touch sensor device from the false sleep mode to the wake-up mode. The touch sensor in the touch sensor unit 20 is electrically connected to the touch electrodes KM to 1G_N, and the touch controller unit 20 receives the electrical signal to sense the position and movement of the initial touch point. Direction and movement path, and use electrical signals to output changes in electrical state. The sensing data generator 140 receives the electrical signals output from the touch sensor unit 2, calculates the position of the initial touch point, the moving direction, and the moving path and stores the equivalent. When the touch state ends, the sensing data generator 140 synthesizes the stored values, and generates and outputs sensing data (such as letter signals, digital signals, and shape signals) corresponding to the input signals. The comparator 170 extracts the sensing data generated by the sensing data generator 14 at regular intervals, and compares the pattern signals (such as letter signals, digital signals, and shape signals) previously stored in the data storage device 110. Measuring data. When there is a pattern signal identical to the sensed data, the comparator 170 outputs an awake mode switching signal to perform the operation indicated by the input signal. On the other hand, when there is no pattern signal identical to the sensed material, the comparator 170 waits in the false sleep mode until another input signal (such as a letter signal, a digital signal, and a shape signal) is input to the touch panel 10. When the comparator 170 outputs the awake mode switching signal, the touch location data generator 180 receives the electrical signal from the touch sensor unit 2, and 15 200949640 and generates and outputs the touch location data, which is awake in response to the comparator i7 The mode switching signal indicates the touch position coordinate. • "Middle" false sleep mode, indicating that the electric-type controller I of the exemplary embodiment of the present invention is placed on the (4) unit 2G, which operates at a lower frequency than normal operation and the other blocks 11〇, 14 〇, 170, and 180 remain in sleep mode. Unlike the prior art, in the prior art, after switching from the sleep mode to the awake mode, the remaining blocks of the electrical touch sensor device operate in an active state. 4 is a block diagram illustrating a connection between a touch electrode in a touch panel and a touch sensor in a touch sensor unit, including a touch electrode 10-N, a reference signal generator 21. The first signal generator 23, the second signal generator 22, and the sensing signal generator 24. The functions of the respective blocks will be described below. The reference signal generator 21 generates a reference signal ref_sig as a clock signal and applies a reference signal to the first signal generator 23 and the second signal generator 22. The first signal generator 23 maintains the delay reference signal ref__sig for the first time to generate the first signal regardless of whether the object touches the touch panel - the sigl 〇 the second signal generator 22 has the touch electrode 10-N by the object touch . When the object does not contact the touch electrode 10-N, the second signal generator 22 generates the second signal S1S2 which does not delay the reference signal ref__sig. On the other hand, when the object is in contact with the touch electrode 10-N, the second signal generator 22 delays the reference signal ref_sig for a longer time than the first time to generate the second signal sig2. In other words, when the object is not in contact with the touch electrode 1〇_N, the second signal generator 22 generates a second signal sig2′ whose phase leads the phase of the first signal sigl and contacts the object with the touch electrode 1〇_N. When it occurs, it generates a second signal sig2 whose phase lags behind the phase of the first signal sigl. Wherein, the object can be any object having a specific capacitance, for example, a body in which a large amount of charge can be accumulated.感 The sense signal generator 24 samples the second signal sig2 and synchronously latches the second _mail with the first sigi to generate a sensing signal, knowing. Wherein, according to the operation mode of the touch sensor chip, the output of the parameter generator can have different frequencies. For example, the wheel may have a low f' before the touch sensor wafer 1() is switched to the awake mode and may have an N frequency after the touch sensor wafer 1()() switches to the awake mode. The lightning touch may not be performed in an instant, therefore, the example allows the electric sensor to respond to the high speed of the touch sensor device after switching to the awake mode. The example reduces power consumption and prevents S according to the present invention. An electrical device of an electrical touch sensor device of an exemplary embodiment that performs an audio operation (such as receiving a radio broadcast program), a video operation (such as receiving a television broadcast) by touching (d) a finger touching the 17 200949640 touch panel 10 Program) and traffic information guidance operations. First, the data storage device 110 inputs the previously stored pattern signals (such as letter signals, digital signals, and shape signals) to the touch panel 10 and can switch the electric touch sensor device from the fake sleep state to the awake mode (S100). 〇

For example, assuming that the shape letter signal is an input for the electric touch sensor device to perform a traffic information guiding operation, the "Λ" shape pattern signal is an input that allows the electric touch sensor device to perform an audio operation. The shape letter signal is an input for the electrical touch sensor device to perform a video operation, and "_, the shape pattern = number is an input for the electrical touch sensor device to continue the previous operation. The mother and the pattern signal are stored in the data. In the storage device 110, when the driver inputs a "Λ" shape pattern on the touch panel 10 by finger touch to listen to the radio broadcast while driving, the panel 10

In the St type „1〇-1 to 1〇_N, the touch electrode that moves the shape pattern of the start point of the driver's finger touches the touch information about the initial touch position and the movement path based on the change of the internal electric power (S250) The surface sensor receives the electric power generated by the driver's finger in the touch type by using the touch and the specific time, and the number and the other electric signal obtained by delaying the reference signal at another specific time. The phase difference is used to output a touch signal, wherein the touch type 200949640 sensor single it 2G senses the position path of the initial touch point and (4) the telecommunication wire input (4) and the shift data generator H0 receive the self-sensor unit 2〇 The electrical signal output, calculate and store the position, moving direction and moving path of the initial defect, and knot the tree in the state, synthesize the stored value, and generate and output the noisy sensing data, ie, The pattern signal corresponding to the wheel signal (S350).

The comparator 170 compares the sensing data of the “λ” shape generated from the sensing data generator 14〇 with the shape letter signal, the “△” shape pattern signal, and “V” previously stored in the data storage device 11〇. "Shape letter signal and shape pattern signal (S4〇〇). When the comparator 170 outputs the awake mode switching signal, the touch location data generator 180 receives the electrical signal from the touch sensor unit 20, and generates and outputs the touch location data in response to the awake mode switching signal of the comparator 170. The data represents the touch location coordinates. Since the data storage device 110 has the same "Λ" shape pattern signal as the sensing data, the comparator 170 outputs the wake mode switching signal 'for performing the audio operation indicated by the corresponding input signal, and touches the position data generator 180. In response to the wake mode switching signal, the touch position coordinates are derived from the output of the touch sensor unit 20 (S500). On the other hand, when the driver erroneously inputs a "<" shape instead of a "Λ" shape pattern signal to the touch panel 10, the comparator 判断0 determines that there is no identical "sensing material" in the data storage device 110. <" shape pattern signal, and waits in the false sleep mode until another signal (such as letter signal, digital signal with 19 200949640 and shape signal) is input to the touch panel 10 without rotating the wake mode switching signal (S150). And , when outputting the awake mode secret for performing the audio operation indicated by the "λ" shape pattern signal, the operation is started in the car navigation (4) audio system, and the user interface associated with the audio system is operated to make the touch The panel displays the display screen required for audio operation (S55〇). Among them, the user interface is designed to use various electronic devices, and 2 is designed to be easy to use. The icon of the computer is a typical example of the user interface. After a certain time, it is judged whether or not the car navigation system can be switched to the sleep mode, quickly switched to another operation, or the like for the purpose of reducing power consumption (S600). When it is determined that the car navigation device can switch to the fake sleep = during operation, the touch controller unit 2 determines whether the driver's finger performs another touch on the touch panel 1G during the operation of the sound (10). = to modulo::=== is enough to fuck ==. And _ touch "==: When = break the car navigator can switch between during operation and touch type sensor unit 2Q ship - sleep mode element 2. judge the tender system - for driving: staff; == 20 ❹ ❹ 200949640 When another touch is performed on the panel ίο for a certain time, the touch panel K) is subjected to another input, such as the letter 222 and the shape signal (S150). In this way, in accordance with the present invention In the electric touch sensor device of the exemplary embodiment, the touch sensor wafer 100 performs all operations that the micro control unit (MCU) f knows to perform, and calculates the position, moving direction, and moving path of the initial point, Generate sensing data, compare the sensed data with the stored letters, numbers, and shape signals, and control the sensor device to perform operations in the active mode. The type of the number (ie, the letter signal, the digital signal, and the shape signal), the touch sensor chip according to the 7F exemplary embodiment of the present invention just outputs the wake-up switching signal 'switching the electric surface device to Awakening mode The various operations of the touch sensor device do not require the operation of a mode switch, thereby performing the functions conventionally performed by the MCU. Conventionally, various types of input devices exist that can touch human letters, digital signals, Shape signals, etc. However, the current consumed by the touch sensor wafer 100 during operation is approximately per channel: 'It is 1/20 or 1/10 of the current consumed by conventional touch sensor wafers. The replacement of the function that is conventionally performed by the MCU can increase the power saving effect. % is quick to implement the above-mentioned age, and the electric touch type device is used. However, the present invention can be applied to make the panel H) (4) through the wire (such as the telephone 2 ❹

200949640 (PDA) and personal media players and computer peripheral devices (computer peripheral devices such as monitors (m〇nit〇r) and mouse). For the sake of convenience, it has been described above that the touch screen unit 2G operates when the wake mode switching signal is applied, and the lying data generator 140 and the comparator 170 continue to operate. However, the operation mode can be switched by an external signal and the sense data generator 140 and the comparator 17 can operate in the sleep mode when the self-touch sensor unit 2 is not output. Furthermore, it has been described above that the touch sensor unit 20 simply outputs information on whether or not a touch is made on the touch panel 10. However, the present invention can be applied to the case where the touch sensor unit 2G outputs the value of the capacitance change caused by the touch. In this case, τ, it is possible to include a capacitance value in the pattern signal previously stored in the data storage device 110 and use the capacitance value 0 to perform three-touch sensing in the exemplary practical touch sensor device of the county. The processor chip can perform the functions conventionally performed by the microcontroller unit (MCU); 3b, and thus by using the touch type on the touch panel to make the wires (4) force >. In addition, the touch sensor device can switch between various operations without the need for an operation mode, thus facilitating pure configuration and requiring a lower level of life. It has been exposed to the above, and the use is not for the month. Anyone skilled in the art can make some changes and refinements without departing from the spirit of the present invention.
