Description

發信器、觸控系統及其發信方法Transmitter, touch system and signaling method thereof

本發明係關於適用於觸控面板的發信器,特別係關於可在干擾時更換頻率的發信器。The present invention relates to a transmitter suitable for use in a touch panel, and more particularly to a transmitter that can change frequency when interfering.

觸控面板或觸控螢幕是相當重要的人機介面,特別是在消費性電子產品上,如手機、平板電腦、或個人數位助理等,觸控螢幕可說是最主要的輸出與輸入裝置。由於電容式觸控螢幕,特別是投射式電容的形式對於手指的部分感應特別靈敏,因此成為市面上主要的觸控面板/螢幕設計之一。Touch panels or touch screens are important human-machine interfaces, especially on consumer electronics such as mobile phones, tablets, or personal digital assistants. Touch screens are the most important output and input devices. Since capacitive touch screens, especially in the form of projected capacitors, are particularly sensitive to partial finger sensing, they are one of the major touch panel/screen designs on the market.

利用指尖觸碰會遮擋住一部份的螢幕,使用者無法清楚地用眼睛確認觸控螢幕所偵測到的點在哪裡。而且使用指尖進行書寫的話,可能無法像使用筆那樣進行精確地控制。因此,使用者除了想使用手指進行觸控之外,也可能同時想要用筆來對觸控螢幕進行輸入。Touching a fingertip can block a portion of the screen, and the user cannot clearly confirm with the eyes where the touch screen detects. Moreover, writing with a fingertip may not be precisely controlled like using a pen. Therefore, in addition to the user's desire to touch with a finger, the user may also want to input the touch screen with a pen.

一般來說,碰觸到觸控螢幕的筆尖面積要比指尖的面積小很多。對於電容式觸控螢幕來說,要偵測到筆所帶來的電容變化是一大挑戰。特別是在許多專業繪圖或排版的應用環境下,在筆的設計上需要增加許多功能按鈕。在這樣的需求下,觸控螢幕不僅僅要偵測到微小的筆尖,還要能夠偵測這些功能按鈕是否被按下。In general, the area of the nib that touches the touch screen is much smaller than the area of the fingertip. For capacitive touch screens, it is a challenge to detect the change in capacitance caused by the pen. Especially in many professional drawing or typesetting applications, many function buttons need to be added to the design of the pen. Under such demand, the touch screen not only detects tiny nibs, but also detects whether these function buttons are pressed.

而且現代人所處的環境有許多電磁干擾,在達成上述目標的同時,還需要能夠避開偵測筆的時候所遭受的電磁干擾。總上所述,市場上需要一種在遭受電磁干擾時還能支援多個功能輸入介面的觸控筆,讓觸控螢幕能在偵測到觸控筆的同時,還能夠偵測到功能按鍵的狀態。Moreover, the environment in which modern people are located has many electromagnetic interferences. In addition to achieving the above objectives, it is also necessary to be able to avoid the electromagnetic interference suffered when detecting the pen. In general, there is a need in the market for a stylus that can support multiple function input interfaces when subjected to electromagnetic interference, so that the touch screen can detect the function of the stylus while detecting the function button. status.

The transmitting method includes: transmitting an electrical signal to a touch device according to at least one transmitter operating state, so that the touch device analyzes the electrical signal to know the operating state of the transmitter, wherein the electrical signal includes a first a frequency or a plurality of first frequencies; detecting whether a received signal includes an interference signal co-ordinated with the electrical signal when the electrical signal is not transmitted; and detecting the electrical signal when the interference signal is detected One or more of the detected first frequencies are replaced with one or more second frequencies.

在更一實施例中,本發明提供一種觸控系統,其包含上述的觸控裝置與發信器。In a further embodiment, the present invention provides a touch system including the above-described touch device and transmitter.

Whether the interfering signal is coherent with the electrical signal sent by the transmitter, and when there is a homology, the frequency of the electrical signal is replaced to avoid interference. .

本發明將詳細描述一些實施例如下。然而,除了所揭露的實施例外,本發明的範圍並不受該些實施例的限定,乃以其後的申請專利範圍為準。而為了提供更清楚的描述及使該項技藝的普通人員能理解本發明的發明內容,圖示內各部分並沒有依照其相對的尺寸進行繪圖,某些尺寸 或其他相關尺度的比例可能被凸顯出來而顯得誇張,且不相關的細節部分並沒有完全繪出,以求圖示的簡潔。The invention will be described in detail below with some embodiments. However, the scope of the present invention is not limited by the embodiments, except as to the disclosed embodiments, which are subject to the scope of the claims. In order to provide a clearer description and to enable those skilled in the art to understand the present invention, the various parts of the drawings are not drawn according to their relative dimensions, some dimensions. The proportions of other relevant scales may be highlighted and exaggerated, and the irrelevant details are not fully drawn for the sake of simplicity.

在一實施例中,本發明所稱的發信器可以是觸控筆。在某些實施例中,發信器可以是其他種放置在觸控面板或螢幕上的物件。比方說,當觸控螢幕呈現遊戲的棋盤時,發信器可以是棋子。遊戲程式偵測棋子在觸控螢幕上的位置之後,即可以得知棋子的位置。In one embodiment, the transmitter referred to in the present invention may be a stylus. In some embodiments, the transmitter can be other items placed on the touch panel or screen. For example, when the touch screen presents the board of the game, the sender can be a piece. After the game program detects the position of the piece on the touch screen, the position of the piece can be known.

無論發信器實際上與觸控面板的接觸面積有多少,其接觸點有幾個,該發信器至少包含一發信定位點。觸控面板或螢幕可以偵測該發信定位點的位置,作為該發信器所表示之物件在觸控面板或螢幕上的代表位置。在一實施例中,該發信器可以不需要接觸觸控面板,僅需要發信定位點靠近觸控面板,即可讓觸控面板偵測到該發信定位點。Regardless of the contact area of the transmitter with the touch panel, there are several contact points, and the transmitter includes at least one signaling anchor point. The touch panel or the screen can detect the position of the transmitting positioning point as a representative position of the object represented by the sender on the touch panel or the screen. In an embodiment, the transmitter can contact the touch panel, and only needs to send the positioning point to the touch panel, so that the touch panel can detect the sending location.

在一實施例中,該發信器可以包含複數個發信定位點。當觸控面板偵測到該複數個發信定位點時,可以偵測到該發信器的面對方向。在更一實施例中,該發信器可以包含m個發信定位點,而當觸控面板偵測到其中的n個發信定位點時,即可能偵測到該發信器在觸控面板上的姿態。比方說,發信器可以是具有四個發信定位點的三角體,每一個發信定位點設置在三角體的頂端。透過偵測接觸到觸控面板上的三個發信定位點,即可以偵測到三角體的哪一面與觸控面板接觸。發信器可以是具有八個發信定位點的正方體,每一個發信定位點設置在正方體的頂端。這種發信器即可以充當骰子使用。In an embodiment, the sender may include a plurality of signaling anchors. When the touch panel detects the plurality of signaling anchor points, the facing direction of the transmitter can be detected. In a further embodiment, the sender may include m signaling anchor points, and when the touch panel detects n of the signaling positioning points, the transmitter may be detected to be in touch. The pose on the panel. For example, the sender can be a triangle with four signaling fix points, each of which is placed at the top of the triangle. By detecting the three signaling positioning points on the touch panel, it is possible to detect which side of the triangle is in contact with the touch panel. The sender can be a cube with eight signaling fix points, each of which is placed at the top of the cube. This type of transmitter can be used as a dice.

請參考第一圖所示,其為根據本發明一實施例的一發信器100的一示意圖。發信器100包含電源模組110、處理模組120、感測器模組 130、頻率合成模組140、信號放大模組150、與發信模組160。如上所述,該發信器100的外型可以作為一觸控筆的形狀。在一實施例中,上述的各個模組可以依照第一圖所示的順序,依序安排在觸控筆的內部,其下端用於和觸控面板接觸或靠近。該發信器100可以包含一總開關,用於啟閉該發信器100的電力。Please refer to the first figure, which is a schematic diagram of a transmitter 100 according to an embodiment of the invention. The transmitter 100 includes a power module 110, a processing module 120, and a sensor module. 130. The frequency synthesizing module 140, the signal amplifying module 150, and the transmitting module 160. As described above, the appearance of the transmitter 100 can be used as the shape of a stylus. In an embodiment, each of the above modules may be arranged in the interior of the stylus in the order shown in the first figure, and the lower end is used to contact or approach the touch panel. The transmitter 100 can include a master switch for turning the power of the transmitter 100 on and off.

該電源模組110可以包含與電力供應與控制相關的電路,例如電池組、直流電對直流電的電壓轉換電路、以及電力管理單元等。上述的電池組可以是可充電電池,也可以是一次性拋棄式電池。當電池組為可充電電池時,該電源模組110可以更包含一充電電路,用於將外界的電源輸入到該充電電池當中。此外,外界的電源可以是以無線的方式輸入到該充電電池,或者是前述的電池組用電容替代。在一實施例中,該充電電路可以包含在電力管理單元當中,用於防止可充電電池的過度放電與過度充電。The power module 110 may include circuits related to power supply and control, such as a battery pack, a direct current to direct current voltage conversion circuit, and a power management unit. The above battery pack may be a rechargeable battery or a disposable disposable battery. When the battery pack is a rechargeable battery, the power module 110 may further include a charging circuit for inputting an external power source into the rechargeable battery. In addition, the external power source may be input to the rechargeable battery in a wireless manner, or the battery pack described above may be replaced with a capacitor. In an embodiment, the charging circuit may be included in the power management unit for preventing overdischarge and overcharging of the rechargeable battery.

上述的處理模組120用於控制該發信器100,其可以包含一微處理器。上述的感測器模組130可以包含至少一種感測器。感測器可以包含例如觸控筆尖的壓力感測器、按鈕、加速度計、電感計、旋鈕等類型的感測器。感測器的狀態可以是二元性質,例如按鈕可以是按下狀態或彈起狀態。加速度計的狀態可以包含靜止或運動中。感測器的狀態也可以是多元性的離散數值,例如壓力感測器所感受的壓力可以分為四段、十段、或十六段。旋鈕的狀態也可以分為四段、八段、十六段等。感測器的狀態也可以是一段類比的區間。上述的處理模組120可以偵測到感測器模組130內感測器的狀態,據而產生一發信器操作狀態。例如筆尖連接一彈性元件,筆尖受壓時,彈性元件會因壓力而形變。前述的壓力感測器連接於彈性元件, 偵測彈性元件承受的壓力。前述的彈性元件可以是一彈簧、彈性橡膠或泡棉、或其他能緩衝壓力使筆尖相對於筆身移動的結構或材質,本發明並不加以限制。此外,前述的壓力感測器可以包括一壓電材料,該壓電材料能因形變產生電性信號。The processing module 120 described above is used to control the transmitter 100, which may include a microprocessor. The sensor module 130 described above may include at least one sensor. The sensor can include a sensor such as a pressure sensor of a stylus tip, a button, an accelerometer, an inductometer, a knob, and the like. The state of the sensor can be binary in nature, for example the button can be in a pressed state or a popped state. The state of the accelerometer can be either stationary or in motion. The state of the sensor can also be a discrete value of diversity. For example, the pressure felt by the pressure sensor can be divided into four segments, ten segments, or sixteen segments. The state of the knob can also be divided into four segments, eight segments, sixteen segments, and the like. The state of the sensor can also be an analogous interval. The processing module 120 can detect the state of the sensor in the sensor module 130, thereby generating a transmitter operating state. For example, when the nib is connected to an elastic member, when the nib is pressed, the elastic member is deformed by pressure. The aforementioned pressure sensor is connected to the elastic element, Detect the pressure on the elastic element. The foregoing elastic member may be a spring, an elastic rubber or a foam, or other structure or material capable of buffering the pressure to move the nib relative to the pen body, which is not limited by the present invention. Furthermore, the aforementioned pressure sensor may comprise a piezoelectric material that is capable of generating an electrical signal due to deformation.

上述的頻率合成模組140包含複數個頻率產生器以及一頻率合成模組或混波器。在一實施例中,上述的複數個頻率產生器可以包含複數個石英震盪器。在另一實施例中,上述的複數頻率產生器可以使用單一個頻率來源,利用除頻器、增頻器、鎖相電路以及其他合適的電路,來產生複數個頻率。這些頻率並不互為諧振波,也和用於偵測該發信器100的觸控面板所發出的頻率不同,也不互為諧振波。因此,可以避開各頻率互相干擾的情況。The frequency synthesizing module 140 includes a plurality of frequency generators and a frequency synthesizing module or a mixer. In an embodiment, the plurality of frequency generators described above may comprise a plurality of quartz oscillators. In another embodiment, the complex frequency generator described above can generate a plurality of frequencies using a single frequency source, using a frequency divider, a frequency multiplier, a phase lock circuit, and other suitable circuitry. These frequencies are not mutually resonant waves, and are different from the frequencies emitted by the touch panel for detecting the transmitter 100, and are not mutually resonant waves. Therefore, it is possible to avoid the situation in which the frequencies interfere with each other.

在某些實施例當中,上述的複數個頻率的範圍落在觸控面板所能偵測的頻率範圍之內。比方說,一般的觸控面板所能偵測的頻率範圍大約是90kHz~250kHz之間,所以複數個頻率產生器所產生的頻率可以落在這個範圍之間。In some embodiments, the range of the plurality of frequencies described above falls within a frequency range detectable by the touch panel. For example, the frequency range that a typical touch panel can detect is about 90 kHz to 250 kHz, so the frequency generated by a plurality of frequency generators can fall within this range.

在一實施例中,上述的處理模組120可以決定頻率合成模組140混合複數個頻率中的那些頻率。也就是可以個別控制某一頻率要不要加入混波器當中,當然也可以控制個別頻率的信號強度。在另一實施例中,上述的處理模組120可以決定頻率合成模組140的各頻率之信號強度的比例。比方說,可以令第一頻率的信號強度與第二頻率的信號強度之比例設為3:7。也可以令第一頻率、第二頻率、第三頻率的信號強度之比例設為24:47:29等。本領域的普通技術人員可以理解到,雖然頻率合成模組140可 以用來產生並且混合多個頻率,但處理模組120根據感測器模組130的各個感測器狀態,也可能令頻率合成模組140產生單一頻率,而不和其他的頻率進行混合。In an embodiment, the processing module 120 may determine that the frequency synthesis module 140 mixes those frequencies in the plurality of frequencies. That is, it is possible to individually control whether a certain frequency is to be added to the mixer, and of course, it is also possible to control the signal strength of the individual frequencies. In another embodiment, the processing module 120 can determine the ratio of the signal strength of each frequency of the frequency synthesis module 140. For example, the ratio of the signal strength of the first frequency to the signal strength of the second frequency can be set to 3:7. It is also possible to set the ratio of the signal strengths of the first frequency, the second frequency, and the third frequency to 24:47:29 or the like. One of ordinary skill in the art will appreciate that although the frequency synthesis module 140 can In order to generate and mix a plurality of frequencies, the processing module 120 may also cause the frequency synthesis module 140 to generate a single frequency without mixing with other frequencies according to the respective sensor states of the sensor module 130.

在一實施例中,某一頻率的信號強度可以相應於感測器模組130當中的裝置在筆尖的壓力感測器,或是具有多段狀態的旋鈕。比方說,在一繪圖軟體當中,觸控筆筆尖的壓力感測器表示筆色的濃郁程度,觸控筆旋鈕的旋轉程度表示筆刷的直徑大小。因此,可以利用第一頻率的信號強度來表示壓力感測器的壓力,還可以利用第二頻率的信號強度來表示旋鈕的旋轉程度。In an embodiment, the signal strength of a certain frequency may correspond to a pressure sensor of the device in the sensor module 130 at the tip of the pen, or a knob having a plurality of segments. For example, in a drawing software, the pressure sensor of the stylus pen tip indicates the richness of the pen color, and the degree of rotation of the stylus knob indicates the diameter of the brush. Therefore, the signal intensity of the first frequency can be used to represent the pressure of the pressure sensor, and the signal strength of the second frequency can also be used to indicate the degree of rotation of the knob.

在另一實施例中,可以利用某一頻率的信號強度佔混合後的信號強度之比例,來對應某一感測器的多元狀態。比方說,第一頻率的信號強度與第二頻率的信號強度之比例為3:7時,表示該感測器的狀態為十段中的第三段,如果是強度比例改為6:4時,則表示該感測器的狀態為時段中的第六段。換言之,如果有三種頻率的話,那麼可以利用第一頻率比第二頻率之第一信號強度比例、第二頻率比第三頻率之第二信號強度比例、以及第三頻率比第一頻率之第三信號強度比例分別表示三種具有多元狀態的感測器的狀態。In another embodiment, the ratio of the signal strength of a certain frequency to the combined signal strength may be utilized to correspond to the multi-state of a certain sensor. For example, when the ratio of the signal strength of the first frequency to the signal strength of the second frequency is 3:7, it indicates that the state of the sensor is the third segment of the ten segments, if the intensity ratio is changed to 6:4. , indicating that the state of the sensor is the sixth segment in the time period. In other words, if there are three frequencies, then the first signal intensity ratio of the first frequency to the second frequency, the second signal strength ratio of the second frequency to the third frequency, and the third frequency to the third frequency of the first frequency may be utilized. The signal strength ratios represent the states of three sensors with multiple states, respectively.

上述的信號放大模組150係用於將上述頻率合成模組140所混合產生的信號放大。在一實施例中,上述的信號放大相應於感測器模組130當中的裝置在筆尖的壓力感測器。假設壓力感測器的電路相應於信號放大模組150的一可變增益放大器(VGA,variable gain amplifier),壓力感測器的電路可以不經過上述的處理模組120,直接控制該可變增益放大器的增 益。因此,該頻率合成模組140所輸出的混合信號將經由該可變增益放大器放大後,送到發信模組160。The signal amplifying module 150 is configured to amplify a signal generated by mixing the frequency synthesizing module 140. In one embodiment, the signal amplification described above corresponds to a pressure sensor of the device in the sensor module 130 at the tip of the pen. Assuming that the circuit of the pressure sensor corresponds to a variable gain amplifier (VGA) of the signal amplifying module 150, the circuit of the pressure sensor can directly control the variable gain without passing through the processing module 120. Amplifier increase beneficial. Therefore, the mixed signal output by the frequency synthesizing module 140 is amplified by the variable gain amplifier and sent to the transmitting module 160.

先前所述,可以利用混合信號當中某一頻率的信號強度來表示一感測器的多元狀態。也可以利用混合信號當中兩個頻率的信號強度比例來表示一感測器的多元狀態。或者是利用混合信號的整體信號強度來表示一感測器的多元狀態。在此同時,可以利用信號放大模組150來放大混合信號,用於表示另一感測器的多元狀態。舉例來說,該發信器100包含兩個具有多元狀態的感測器,一是裝置在筆尖的壓力感測器,其二是裝置在筆身的旋鈕。兩者分別用來表示筆觸的色深與直徑大小。在一實施例中,可以利用混合信號的強度來表示壓力感測器所受到的壓力大小,旋鈕的狀態則是利用混合信號當中兩個頻率的信號強度比例來表示,或者是以整體混合信號利用信號放大模組150放大或降低至特定的強度來表示旋鈕的特定狀態。As previously stated, the signal strength of a frequency in a mixed signal can be utilized to represent the multi-state of a sensor. It is also possible to use the ratio of the signal intensities of the two frequencies in the mixed signal to represent the multivariate state of a sensor. Or the overall signal strength of the mixed signal is used to represent the multi-state of a sensor. At the same time, the signal amplification module 150 can be utilized to amplify the mixed signal for indicating the multi-state of the other sensor. For example, the transmitter 100 includes two sensors having a multi-state state, one being a pressure sensor of the device at the tip of the pen, and the other being a knob of the device at the pen body. The two are used to indicate the color depth and diameter of the stroke. In an embodiment, the intensity of the mixed signal can be used to indicate the magnitude of the pressure experienced by the pressure sensor, and the state of the knob is represented by the ratio of the signal strength of the two frequencies in the mixed signal, or the overall mixed signal is utilized. The signal amplification module 150 amplifies or reduces to a particular intensity to indicate a particular state of the knob.

在本發明的一實施例中,上述的發信模組160係包含裝置在筆尖的壓力感測器。該發信模組160可以是一組天線或一具有適當阻抗值的導體或電極,或可稱之為激勵電極。該筆尖的導體或電極連接到該壓力感測器。當發信模組160發出信號,而且接觸到觸控面板/螢幕時,信號就會流入觸控面板/螢幕的感測電極。當發信模組160靠近但未接觸到觸控面板/螢幕的時候,觸控面板/螢幕的感測電極也會感應到發信模組160上的信號變化量,進而使觸控面板/螢幕偵測到該發信器100靠近。In an embodiment of the invention, the signaling module 160 includes a pressure sensor with a device at the tip of the pen. The signaling module 160 can be a set of antennas or a conductor or electrode having a suitable impedance value, or can be referred to as an excitation electrode. The conductor or electrode of the nib is connected to the pressure sensor. When the signaling module 160 signals and touches the touch panel/screen, the signal flows into the sensing electrodes of the touch panel/screen. When the transmitting module 160 is close to but not touched to the touch panel/screen, the sensing electrodes of the touch panel/screen also sense the amount of signal change on the transmitting module 160, thereby enabling the touch panel/screen The sender 100 is detected to be close.

當該頻率合成模組140可以合成n種頻率時,就可以利用信號的頻率來調變出2n 個操作狀態。比方說,當n等於三時,可以利用信號的頻 率調變出八個操作狀態。請參照表一所示,其為根據本發明一實施例的發信器操作狀態與各感測器狀態的一表示。When the frequency synthesizing module 140 can synthesize n kinds of frequencies, the frequency of the signal can be used to modulate 2 n operating states. For example, when n is equal to three, eight operating states can be modulated using the frequency of the signal. Referring to Table 1, it is a representation of the operating state of the transmitter and the state of each sensor in accordance with an embodiment of the present invention.

在表一所示的實施例中,該感測器模組130包含三個感測器,分別是筆尖的壓力感測器、第一按鈕、與第二按鈕。這三個感測器的狀態都是二元狀態,因此組合起來有八種發信器操作狀態,如表一所示。 本領域的普通技術人員可以理解到,上述的發信器操作狀態與各感測器狀態可以隨意調換位置。比方說第一發信器操作狀態可以和其他的發信器操作狀態對調,如第七發信器操作狀態。In the embodiment shown in Table 1, the sensor module 130 includes three sensors, which are a pressure sensor of the pen tip, a first button, and a second button. The states of the three sensors are all binary states, so there are eight transmitter operating states combined, as shown in Table 1. A person of ordinary skill in the art can understand that the above-mentioned transmitter operating state and each sensor state can be arbitrarily changed positions. For example, the first transmitter operating state can be reversed with other transmitter operating states, such as the seventh transmitter operating state.

請參考表二所示,其為根據本發明一實施例的發信器操作狀態與各頻率的一表示。已如前述,該頻率合成模組140可以合成三種不同頻率。所以可以將各個發信器操作狀態對應到各個頻率。如表二所示。本領域的普通技術人員可以理解到,上述的發信器操作狀態與各感測器狀態可以隨意調換位置。比方說第一發信器操作狀態可以和其他的發信器操作狀態對調,如第八發信器操作狀態。Please refer to Table 2, which is a representation of the operating state of the transmitter and each frequency in accordance with an embodiment of the present invention. As described above, the frequency synthesis module 140 can synthesize three different frequencies. Therefore, each transmitter operation state can be mapped to each frequency. As shown in Table 2. A person of ordinary skill in the art can understand that the above-mentioned transmitter operating state and each sensor state can be arbitrarily changed positions. For example, the first transmitter operating state can be reversed with other transmitter operating states, such as the eighth transmitter operating state.

在一實施例中,當筆尖的壓力感測器感測器沒有感受到壓力時,該發信器100仍然混合頻率並發出信號。在另一實施例中,當筆尖的壓力感測器感測器沒有感受到壓力時,該發信器100就不混合頻率,也不發出信號。對照到表二,此狀態就是第七發信器操作狀態。在此實施例中,表一可以修改為表三。In one embodiment, the transmitter 100 still mixes the frequency and signals when the pressure sensor sensor of the pen tip does not sense the pressure. In another embodiment, the transmitter 100 does not mix frequencies and does not signal when the pressure sensor sensor of the pen tip does not sense the pressure. Referring to Table 2, this state is the seventh transmitter operating state. In this embodiment, Table 1 can be modified to Table 3.

在表一至表三所示的實施例當中,該發信器100所發出的信號僅利用頻率的合成作為信號調變的因子。在接下來的實施例中,除了頻率的合成之外,該發信器100可以再加上信號強度與/或各頻率信號強度的比例作為信號調變的因子。In the embodiments shown in Tables 1 to 3, the signal emitted by the transmitter 100 utilizes only the synthesis of frequencies as a factor of signal modulation. In the following embodiments, in addition to the synthesis of the frequency, the transmitter 100 may add a ratio of signal strength and/or signal strength of each frequency as a factor of signal modulation.

請參考表四所示,其為根據本發明一實施例的發信器頻率狀態與各感測器狀態的一表示。和表一所示的實施例相比,壓力感測器所感測得知的狀態不再只限於有/無接觸壓力的二元狀態,而是大於二的多元狀態。因此,在表四的左列並不能稱為發信器操作狀態,只能稱為發信器頻率狀態。此實施例的發信器操作狀態的調變因子除了頻率狀態之外,還要考慮到信號強度。Please refer to Table 4, which is a representation of the transmitter frequency state and the state of each sensor in accordance with an embodiment of the present invention. Compared with the embodiment shown in Table 1, the state sensed by the pressure sensor is no longer limited to the binary state with/without contact pressure, but to the multi-state of greater than two. Therefore, the left column of Table 4 cannot be called the transmitter operating state and can only be called the sender frequency state. The modulation factor of the transmitter operating state of this embodiment takes into account the signal strength in addition to the frequency state.

請參考表五所示,其為本發明一實施例的發信器操作狀態與各頻率及信號強度的一表示。其中,該信號強度調變可以是混合信號的信號強度值,例如是壓力感測器的接觸壓力段數。Please refer to Table 5, which is a representation of the operating state of the transmitter and the frequencies and signal strengths according to an embodiment of the invention. Wherein, the signal strength modulation may be a signal strength value of the mixed signal, for example, the number of contact pressure segments of the pressure sensor.

在表五的實施例中,由於第五到第八發信器頻率狀態所對應的壓力感測器之接觸壓力段數為零,因此其信號強度調變的結果也可以為零。換言之,即不發出信號。在另一實施例中,其信號強度調變可以是一固定值,其固定信號強度可以不同於相應於壓力感測器的接觸壓力段數之信號強度。In the embodiment of Table 5, since the number of contact pressure segments of the pressure sensor corresponding to the fifth to eighth transmitter frequency states is zero, the result of the signal strength modulation can also be zero. In other words, no signal is sent. In another embodiment, the signal strength modulation may be a fixed value, and the fixed signal strength may be different from the signal strength corresponding to the number of contact pressure segments of the pressure sensor.

請參考第二圖所示,其為根據本發明一實施例的一發信方法 的一流程示意圖。該發信方法可以適用於第一圖所示的發信器100,但不限於此。該發信方法包含兩個步驟,在步驟210當中,根據該發信器所包含的一感測器模組內的狀態產生一發信器操作狀態。以及在步驟220當中,根據該發信器操作狀態發送一電信號至至一觸控裝置,使得該觸控裝置分析該電信號後得知該發信器操作狀態與該發信器與該觸控裝置的一相對位置,其中該電信號係由複數個頻率混合而成。Please refer to the second figure, which is a signaling method according to an embodiment of the present invention.

The pressure sensor can be used to sense the degree of contact pressure between the transmitter and the touch device.

當該感測器模組內包含複數個感測器時,該發信器操作狀態的可能狀態數量為每一該複數個感測器的可能狀態數量的總和。或者是在另一實施例中,該發信器操作狀態表示為每一該複數個感測器的狀態表示的任意組合之一。在一實施例中,該感測器模組內的一感測器之狀態表示為二的倍數n,其中n為大於或等於0的整數。When the sensor module includes a plurality of sensors, the number of possible states of the transmitter operating state is the sum of the number of possible states of each of the plurality of sensors. Or in another embodiment, the transmitter operational state is represented as one of any combination of state representations for each of the plurality of sensors. In one embodiment, the state of a sensor within the sensor module is represented as a multiple of two, where n is an integer greater than or equal to zero.

In one embodiment, the signal strength of the electrical signal corresponds to the state of the sensor having a multivariate state within the sensor module. In another embodiment, the signal strength of the first frequency and the second frequency mixed by the electrical signal corresponds to a state of the sensor having a multi-state in the sensor module.

The touch system 300 includes at least one transmitter 100, a touch panel 320, a touch processing device 330, and a host 340. In the present embodiment, the transmitter 100 can be applied to the transmitter described in the above embodiments, and is particularly suitable for the embodiments shown in the first and second figures. It is also worth noting that the touch system 300 can include a plurality of transmitters 100. The touch panel 320 is formed on a substrate, and the touch panel 320 can be a touch screen.

The signal is used to detect the relative position of the starter 100 and the touch panel 320. Since the signal of the transmitter 100 is different from the frequency of the mutual capacitance or the self-capacitance driving signal, and is not mutually resonant, the touch processing device 330 can separately distinguish the signal and mutual capacitance emitted by the starter 100 or Self-capacitance signal. The present invention will be described in detail in the following paragraphs. In another embodiment, the touch panel 320 can be a surface capacitive touch panel having one electrode at four corners or four sides.

In an embodiment, the touch processing device 300 can include only one receiver analog front end 410.

Next, the integrated signal will be sent by the integrators 530I and 530Q to the squarers 540I and 540Q, respectively. Finally, the outputs of the squarers 540I and 540Q will be summed by the rms 550 of the sum before the root mean square. In this way, the signal strength corresponding to the frequency of the signal generated by the signal generator 510 can be obtained. When the signal strengths of all frequencies are taken, the signal strength ratio for every two or any two frequencies, as well as the total signal strength, can be generated.

請參考第六圖所示,其為根據本發明一實施例的一數位解調 變器420的一部份方塊示意圖。和第五圖所示的實施例相比,第六圖所示的實施例係採用數位的方式來進行。同樣地,可以使用單一個第六圖所示的數位解調變器來解調變每一個頻率。也可以使用多個第六圖所示的數位解調變器來解調變多個頻率,比方說當該發信器100可以發出N種頻率時,即時用N個第六圖所示的數位解調變器來解調每一個頻率。信號產生器610係用於產生相應頻率的數位信號。Please refer to the sixth figure, which is a digital demodulation according to an embodiment of the invention. A partial block diagram of the transformer 420. Compared with the embodiment shown in the fifth figure, the embodiment shown in the sixth figure is performed in a digital manner. Similarly, a digital demodulator as shown in the sixth figure can be used to demodulate each frequency. It is also possible to use a plurality of digital demodulation transformers shown in the sixth figure to demodulate a plurality of frequencies, for example, when the transmitter 100 can emit N kinds of frequencies, the N digits shown in the sixth figure are immediately used. Demodulation transformer to demodulate each frequency. Signal generator 610 is used to generate digital signals of corresponding frequencies.

從該接收器類比前端410所接收的類比信號,可以經由可選的放大器600,再送往類比數位轉換器605。該類比數位轉換器605的取樣頻率將相應於該信號產生器610所發出信號的頻率。換言之,當類比數位轉換器605在一第一相位進行一次取樣時,該信號產生器610將分別送出一次第一相位信號到兩個混波器620I與620Q,在一第二相位進行一次取樣時,該信號產生器610將分別送出一次第二相位信號到兩個混波器620I與620Q。混波器620I接收該信號產生器610所輸出的餘弦信號並與數位轉換器605的信號相乘以產生混波信號,混波器620Q接收該信號產生器610所輸出的正弦信號並與數位轉換器605的信號相乘以產生混波信號。例如混波器620I將第一相位信號與第一相位的餘弦信號相乘以產生兩者乘積的混波信號,混波器620Q將第一相位信號與第一相位的正弦信號相乘以產生兩者乘積的混波信號。兩個混波器620I與620Q所輸出的混波信號將分別輸出到加法積分器630I與630Q。接著,加法積分完畢的信號將由加法積分器630I與630Q分別送往平方器640I與640Q。最後,平方器640I與640Q的輸出將由總和之均方根器650先加總後,再求均方根。如此一來,就可以得到相應於該信號產生器610所產生之信號頻率的信號強度。當取得所有頻率的信號強度之後,即可以 產生每兩個頻率的信號強度比例,以及總信號強度。在第六圖中,前述類比數位轉換器605取樣後的信號為數位信號,在後的信號處理皆為數位信號處理。The analog signal received from the receiver analog front end 410 can be sent to the analog digital converter 605 via the optional amplifier 600. The sampling frequency of the analog to digital converter 605 will correspond to the frequency of the signal emitted by the signal generator 610. In other words, when the analog-to-digital converter 605 performs a sampling in a first phase, the signal generator 610 will send the first phase signal once to the two mixers 620I and 620Q, respectively, and perform sampling at a second phase. The signal generator 610 will send the second phase signal once to the two mixers 620I and 620Q, respectively. The mixer 620I receives the cosine signal output by the signal generator 610 and multiplies the signal of the digital converter 605 to generate a mixed signal, and the mixer 620Q receives the sinusoidal signal output by the signal generator 610 and performs digital conversion. The signals of the 605 are multiplied to produce a mixed signal. For example, the mixer 620I multiplies the first phase signal by the cosine signal of the first phase to generate a mixed signal of the product of the two, and the mixer 620Q multiplies the first phase signal by the sinusoidal signal of the first phase to generate two The product of the mixed signal. The mixed signals output by the two mixers 620I and 620Q are output to the adder integrators 630I and 630Q, respectively. Next, the addition-completed signal is sent by the adder integrators 630I and 630Q to the squarers 640I and 640Q, respectively. Finally, the outputs of the squarers 640I and 640Q will be summed by the rms 650 of the sum, and then the root mean square. In this way, the signal strength corresponding to the signal frequency generated by the signal generator 610 can be obtained. After taking the signal strength of all frequencies, you can Produces a ratio of signal strength for every two frequencies, as well as the total signal strength. In the sixth figure, the signal sampled by the analog-to-digital converter 605 is a digital signal, and the subsequent signal processing is digital signal processing.

請參考第七圖所示,其為根據本發明一實施例的一數位解調變器420的一部份方塊示意圖。第七圖所示的實施例係採用數位的方式來進行,可以使用單一個第七圖所示的數位解調變器來解調變出每一個頻率。從該接收器類比前端410所接收的類比信號,可以經由可選的放大器700,再送往類比數位轉換器710。接著,再將輸出的數位信號送往傅立葉轉換器720,即可以解調變出頻域上各個頻率的信號強度。上述的傅立葉轉換器可以是數位化的快速傅立葉轉換器。Please refer to the seventh figure, which is a partial block diagram of a digital demodulator 420 according to an embodiment of the invention. The embodiment shown in the seventh figure is performed in a digital manner, and a digital demodulator as shown in the seventh figure can be used to demodulate and change each frequency. The analog signal received from the receiver analog front end 410 can be sent to the analog digital converter 710 via the optional amplifier 700. Then, the output digital signal is sent to the Fourier converter 720, and the signal strength of each frequency in the frequency domain can be demodulated. The above-described Fourier converter may be a digitalized fast Fourier converter.

請參考第八圖所示,其為根據第七圖之數位解調變器420所解調變之一結果示意圖。第八圖所示的結果僅僅為一示例,除了使用圖表的方式表示外,也可以使用各式各樣的資料結構來儲存解調變的結果。第八圖的橫軸為信號頻率,其豎軸為信號強度。可以從傅立葉轉換器720的計算結果得到相應於該發信器100所可能發出的N種頻率的信號強度。在一實施例中,可以對信號強度設定一門檻值。大於該門檻值的信號強度才認為信號中含有其相應的頻率。當得出各個頻率的信號強度之後,也就可以進而計算出每兩個頻率的信號強度比例,以及總信號強度。Please refer to the eighth figure, which is a schematic diagram of the result of demodulation of the digital demodulator 420 according to the seventh figure. The results shown in the eighth figure are only an example, and in addition to the use of a graphical representation, a variety of data structures can be used to store the results of the demodulation. The horizontal axis of the eighth graph is the signal frequency, and the vertical axis is the signal strength. The signal strength corresponding to the N frequencies that may be emitted by the transmitter 100 can be obtained from the calculation result of the Fourier converter 720. In an embodiment, a threshold value can be set for the signal strength. A signal strength greater than the threshold value is considered to contain its corresponding frequency. After the signal strengths of the respective frequencies are obtained, the signal strength ratio for each of the two frequencies and the total signal strength can be calculated.

儘管第五圖至第七圖所舉出的三個解調變器420之實施例可以實作在第三圖所示的觸控處理裝置330當中,但本發明並不限定該觸控處理裝置330必須要實作出解調變器420的所有步驟。在某些實施例當中,解調變器420的某些步驟可以交由主機340來執行。另外值得注意的是,儘管 數位解調變器420之實施例可以使用特定的硬體來實作,但本領域的普通技術人員可以理解到,也可以使用軟體或韌體的方式來實施數位解調變器420的各個元器件。舉例來說,混波器可以藉由乘法來實現,加法積分器可以藉由加法來實現,而乘法與加法是一般處理器最常見的運算指令。Although the embodiments of the three demodulation transformers 420 illustrated in the fifth to seventh embodiments can be implemented in the touch processing device 330 shown in the third embodiment, the present invention is not limited to the touch processing device. All steps of the demodulator 420 must be implemented 330. In some embodiments, certain steps of demodulator 420 may be performed by host 340. Also worth noting is that despite Embodiments of the digital demodulation 420 can be implemented using a particular hardware, but one of ordinary skill in the art will appreciate that the various elements of the digital demodulation 420 can also be implemented using software or firmware. Device. For example, a mixer can be implemented by multiplication, an addition integrator can be implemented by addition, and multiplication and addition are the most common operational instructions of a general processor.

請參考第九A圖所示,其為根據本發明一實施例的一感測發信器方法的一流程示意圖。在步驟910當中,計算每一個第一電極與第二電極所接收之該電信號的總信號強度。步驟910可以利用第三圖到第七圖所示的實施例來實施。接著,在步驟920當中,根據計算出的總信號強度,計算發信器與觸控裝置的一相對位置。在一實施例中,可以認為該發信器的位置相應於具有最大總信號強度的第一電極與第二電極。在另一實施例中,可以認為該發信器的位置相應於具有最大總信號強度的相鄰第一電極與相鄰第二電極的質心,其質量的大小係相應於信號的強度。最後,在可選的步驟930當中,可以根據發信器所發出的電信號資訊,計算該發信器操作狀態。本領域的普通技術人員可以理解到,步驟930的實作可以根據前述的各表來進行回推。Please refer to FIG. 9A, which is a schematic flowchart of a method for sensing a transmitter according to an embodiment of the invention. In step 910, a total signal strength of the electrical signal received by each of the first electrode and the second electrode is calculated. Step 910 can be implemented using the embodiments shown in the third to seventh figures. Next, in step 920, a relative position of the sender and the touch device is calculated based on the calculated total signal strength. In an embodiment, the position of the transmitter can be considered to correspond to the first electrode and the second electrode having the greatest total signal strength. In another embodiment, the position of the transmitter can be considered to correspond to the centroid of the adjacent first electrode and the adjacent second electrode having the largest total signal strength, the magnitude of which corresponds to the strength of the signal. Finally, in an optional step 930, the transmitter operating state can be calculated based on the electrical signal information sent by the sender. One of ordinary skill in the art will appreciate that the implementation of step 930 can be pushed back according to the various tables described above.

請參考第九B圖,其為根據本發明一實施例的一感測發信器方法的一流程示意圖。在步驟905當中,可以計算每一個第一電極或第二電極所接收之該電信號的總信號強度。當解調變出第一電極或第二電極所接收之該電信號之後,就可以得知發信器所發出信號的頻率為何。比方說,發信器若發出第一頻率與第二頻率,而未發出第三頻率時,則在步驟915所執行的另一電極的總信號強度之計算過程中,就可以省略掉第三頻率的計算。如果採用第七圖所示的數位解調變器,則不須採用第九B圖所示的方 法。但如果採用第五圖或第六圖所述的解調變器,而且解調變器的數量不足以一次對所有頻率進行掃描時,此種做法可以節省一些時間與計算資源。而且,如果當第一電極或第二電極的計算之後,並沒有發現發信器所發出的電信號,則可以省略執行步驟915。反之,當發現發信器所發出的電信號之後,則步驟915可以根據所接收之該電信號的各頻率信號強度,計算另一電極所接收之該電信號的總信號強度。其餘的步驟920與930可以適用第九A圖的實施例之說明。Please refer to FIG. BB, which is a schematic flowchart of a method for sensing a transmitter according to an embodiment of the invention. In step 905, the total signal strength of the electrical signal received by each of the first or second electrodes can be calculated. After the demodulation changes the electrical signal received by the first electrode or the second electrode, the frequency of the signal sent by the transmitter can be known. For example, if the transmitter sends the first frequency and the second frequency without emitting the third frequency, the third frequency can be omitted during the calculation of the total signal strength of the other electrode performed in step 915. Calculation. If the digital demodulator shown in Figure 7 is used, the square shown in Figure EB is not required. law. However, if the demodulator described in Figure 5 or Figure 6 is used and the number of demodulators is not sufficient to scan all frequencies at once, this can save some time and computational resources. Moreover, if the electrical signal emitted by the transmitter is not found after the calculation of the first electrode or the second electrode, step 915 may be omitted. Conversely, after the electrical signal sent by the transmitter is found, step 915 can calculate the total signal strength of the electrical signal received by the other electrode based on the received frequency signal strength of the electrical signal. The remaining steps 920 and 930 may be applied to the description of the embodiment of Figure IX.

要注意的是,在第九A圖與第九B圖的流程當中,若沒有提到步驟之間的因果關係或順序,則本發明並不限定這些步驟所執行的先後順序。另外,在步驟905、910、915當中提到了計算每一個第一電極與/或第二電極所接收之該電信號的總信號強度。在一實施例中,若該觸控系統300當中只包含單一個發信器100時,第九A圖與第九B圖的流程就可以修改為,當計算到至少一個第一電極與第二電極所接收之該電信號的總強度大於一門檻值時,即可以執行步驟920與步驟930。It is to be noted that, in the flow of the ninth A and ninth B, if the causal relationship or order between the steps is not mentioned, the present invention does not limit the order in which the steps are performed. Additionally, it is mentioned in steps 905, 910, 915 that the total signal strength of the electrical signal received by each of the first and/or second electrodes is calculated. In an embodiment, if only one single transmitter 100 is included in the touch system 300, the processes of the ninth A and ninth B diagrams may be modified to calculate at least one first electrode and the second Step 920 and step 930 may be performed when the total intensity of the electrical signal received by the electrode is greater than a threshold.

總上所述,本發明的主要精神之一,在於利用偵測第一電極與第二電極所接收信號中的相應於多個頻率的信號強度,進而計算出發信器與觸控裝置之間的一相對位置,還可以由回推該發信器操作狀態得知該發信器上各個感測器的狀態。此外,本發明還可以利用電容式觸控面板的觸控電極,使得同一個電容式觸控面板可以進行電容式的偵測,也可以進行發信器的偵測。換言之,利用同一個電容式觸控面板即可以進行手指偵測、手掌偵測,也可以進行發信器式觸控筆的偵測。In summary, one of the main spirits of the present invention is to detect the signal strength corresponding to multiple frequencies in the signals received by the first electrode and the second electrode, thereby calculating the relationship between the starter and the touch device. In a relative position, the state of each sensor on the sender can also be known by pushing back the transmitter operating state. In addition, the present invention can also utilize the touch electrodes of the capacitive touch panel, so that the same capacitive touch panel can perform capacitive detection and can also detect the transmitter. In other words, the same capacitive touch panel can be used for finger detection, palm detection, and detection of a transmitter-type stylus.

請參考第十圖所示,其為根據本發明一實施例的一發信器 1000之一方塊示意圖。第十圖所示的發信器1000中的各元件,如果沒有特別提到的地方,可以沿用或衍生自第一圖所示之發信器100中的各元件。除此之外,第三圖所示的觸控系統300當中,也可以將發信器100替換為發信器1000。Please refer to the tenth figure, which is a transmitter according to an embodiment of the present invention. A schematic diagram of one of the 1000 blocks. The components of the transmitter 1000 shown in the tenth embodiment, if not specifically mentioned, may be used or derived from the components of the transmitter 100 shown in the first figure. In addition, in the touch system 300 shown in the third figure, the transmitter 100 can also be replaced with the transmitter 1000.

發信器1000更包含了一偵測模組170。此偵測模組170係用來在該發信模組160未發出電信號時,接收一信號,並且偵測該接收信號當中與電信號同調(coherent)的干擾信號。假如偵測到與電信號同調的干擾信號的話,該處理模組120或稱處理模組會將電信號當中被干擾的一個或多個第一頻率更換為一個或多個第二頻率。The transmitter 1000 further includes a detection module 170. The detection module 170 is configured to receive a signal when the signaling module 160 does not emit an electrical signal, and detect an interference signal that is coherent with the electrical signal among the received signals. The processing module 120 or the processing module replaces one or more first frequencies that are interfered with among the electrical signals into one or more second frequencies, if an interference signal that is co-ordinated with the electrical signal is detected.

在一實施例中,該接收信號可以從該發信器1000外部的任何地方接收,例如可以利用該發信器1000的外殼來接收信號,特別是來自握持該發信器1000的人體。在另一實施例中,可以從該發信器1000與該觸控面板320接觸的地方接收信號。在某一實施例中,上述該發信器1000與該觸控面板320接觸的地方,也就是該發信模組160發出電信號的地方。由於該偵測模組170是在該發信模組160不發出電信號的時候進行偵測,所以可以分時地利用發出電信號的導體或天線。In an embodiment, the received signal may be received from anywhere outside of the transmitter 1000, for example, the housing of the transmitter 1000 may be utilized to receive signals, particularly from a human body holding the transmitter 1000. In another embodiment, a signal can be received from where the transmitter 1000 is in contact with the touch panel 320. In one embodiment, the location where the sender 1000 contacts the touch panel 320, that is, where the signaling module 160 sends an electrical signal. Since the detection module 170 detects when the transmission module 160 does not emit an electrical signal, the conductor or antenna that emits the electrical signal can be utilized in a time-sharing manner.

請參考表六所示,其為本發明一實施例的發信器操作狀態與各頻率的一表示。在表六所示的實施例當中,同一發信器操作狀態可以利用兩種不同的頻率來表示。無論是利用哪一種頻率來表示該發信器操作狀態,觸控處理裝置340都會解讀出該發信器操作狀態。Please refer to Table 6, which is a representation of the operating state of the transmitter and each frequency according to an embodiment of the present invention. In the embodiment shown in Table 6, the same transmitter operating state can be represented by two different frequencies. Regardless of which frequency is used to indicate the transmitter operating state, the touch processing device 340 interprets the transmitter operating state.

儘管表六對於同一種發信器操作狀態只示出兩種頻率組合,但在其他的實施例中,可以三種或多種不同的頻率組合來表示同一種發信器操作狀態。當該偵測模組170偵測到該接收信號當中有與電信號同調的干擾信號時,處理模組120可以更換該電信號的另一種頻率組合。Although Table 6 shows only two frequency combinations for the same transmitter operating state, in other embodiments, three or more different frequency combinations may be used to represent the same transmitter operating state. When the detection module 170 detects that the received signal has an interference signal that is co-ordinated with the electrical signal, the processing module 120 can replace another frequency combination of the electrical signal.

表六所示的實施例當中,更換前後的頻率組合都是一個頻率對一個頻率。也就是第二頻率來更換第一頻率,第四頻率來更換第三頻率,或反之。在表七所示的實施例當中,表示同一發信器操作狀態的頻率組合可以不限於一個頻率,也可以是多種頻率混合而成。In the embodiment shown in Table 6, the frequency combinations before and after replacement are one frequency versus one frequency. That is, the second frequency is used to replace the first frequency, and the fourth frequency is to replace the third frequency, or vice versa. In the embodiment shown in Table 7, the frequency combination indicating the operation state of the same transmitter may not be limited to one frequency, or may be a mixture of a plurality of frequencies.

有兩個頻率組合對應到表七實施例的第一發信器操作狀態,第五頻率混合第六頻率是第一頻率組合,第七頻率是第二頻率組合。在這一個範例當中,無論是干擾信號當中包含第五頻率或第六頻率,處理 模組120會將停止將第五頻率與第六頻率混合到電信號當中,直接以第七頻率作為電信號。或者反過來,當干擾信號當中包含第七頻率時,處理模組120會將停止將第七頻率作為電信號,而是混和第五頻率與第六頻率作為電信號。There are two frequency combinations corresponding to the first transmitter operating state of the seven embodiment, the fifth frequency mixing sixth frequency is the first frequency combination, and the seventh frequency is the second frequency combination. In this example, whether the interference signal contains the fifth frequency or the sixth frequency, processing The module 120 will stop mixing the fifth frequency and the sixth frequency into the electrical signal, and directly use the seventh frequency as the electrical signal. Or conversely, when the interference signal includes the seventh frequency, the processing module 120 stops using the seventh frequency as an electrical signal, and mixes the fifth frequency and the sixth frequency as electrical signals.

在第二發信器操作狀態的範例當中,當干擾信號包含第八頻率或第九頻率時,會以第十頻率混合第十一頻率作為電信號。反之,若干擾信號包含第十頻率或第十一頻率時,會以第八頻率混合第九頻率作為電信號。在第三發信器操作狀態的範例裡,說明替換頻率組合不限於兩個頻率,可以及於三個或多個以上的頻率。In the example of the second transmitter operating state, when the interference signal includes the eighth frequency or the ninth frequency, the eleventh frequency is mixed as the electrical signal at the tenth frequency. On the other hand, if the interference signal includes the tenth frequency or the eleventh frequency, the ninth frequency is mixed with the eighth frequency as an electrical signal. In the example of the third transmitter operating state, it is explained that the replacement frequency combination is not limited to two frequencies, and may be equal to three or more frequencies.

在第四發信器操作狀態的範例裡,第一頻率組合中有第十六頻率與第十七頻率。假設干擾信號包含第十六頻率而不包含第十七頻率時,則可以將第十六頻率更換成第十八頻率。假設干擾信號包含第十七頻率而不包含第十六頻率時,則可以將第十七頻率更換成第十八頻率。又或者干擾信號中的第十六頻率的信號強度大於第十七頻率的信號強度時,則可以將第十六頻率更換成第十八頻率。又或者干擾信號中的第十七頻率的信號強度大於第十六頻率的信號強度時,則可以將第十七頻率更換成第十八頻率。In the example of the fourth transmitter operating state, the first frequency combination has a sixteenth frequency and a seventeenth frequency. Assuming that the interference signal includes the sixteenth frequency and does not include the seventeenth frequency, the sixteenth frequency can be replaced with the eighteenth frequency. Assuming that the interference signal includes the seventeenth frequency and does not include the sixteenth frequency, the seventeenth frequency can be replaced with the eighteenth frequency. Alternatively, when the signal strength of the sixteenth frequency in the interference signal is greater than the signal strength of the seventeenth frequency, the sixteenth frequency can be replaced with the eighteenth frequency. Alternatively, when the signal strength of the seventeenth frequency in the interference signal is greater than the signal strength of the sixteenth frequency, the seventeenth frequency can be replaced with the eighteenth frequency.

儘管在表七當中,對應到第四發信器操作狀態的第二頻率組合有兩種,其等同於對應到第四發信器操作狀態的頻率組合是三種,各自由第十六頻率、第十七頻率、與第十八頻率當中選擇兩種進行混合。當三種頻率當中的某一頻率包含在干擾信號時,或是干擾信號當中某一頻率的信號強度達於其他兩者時,可以用另外兩者混合的電信號來表示該發信器 操作狀態。在本發明的一實施例中,可以選用多個頻率的混合來表示一種發信器操作狀態。當干擾信號包含其中的一個或多個頻率,即可以換用其他未被干擾或是干擾程度較小的頻率。Although in Table 7, there are two combinations of the second frequencies corresponding to the operational state of the fourth transmitter, which are equivalent to three combinations of frequencies corresponding to the operational state of the fourth transmitter, each of the sixteenth frequency, Seventeen frequencies are selected and mixed with the eighteenth frequency. When one of the three frequencies is included in the interference signal, or the signal strength of one of the interference signals is higher than the other two, the electrical signal mixed by the other two may be used to represent the transmitter. Operating status. In an embodiment of the invention, a mixture of multiple frequencies may be selected to indicate a transmitter operating state. When the interference signal contains one or more of the frequencies, it can be switched to other frequencies that are not interfered or have a small degree of interference.

先前段落中曾經提到,當使用多個頻率來表示一個具有多元狀態的發信器操作狀態時,可以調整每一個頻率之信號強度以便表示該多元狀態。比方說,在前述的第四發信狀態可以對應到發信器1000所受到的壓力程度。例如在混合第十六頻率與第十七頻率時,兩者的信號強度可以為六比四,用於表示發信器1000所受壓力程度為60%。當干擾信號當中包含第十六頻率而改用第十八頻率時,則第十八頻率與第十七頻率兩者的信號強度可以為六比四,同樣可以表示發信器1000所受壓力程度為60%。類似地,當干擾信號當中包含第十七頻率而改用第十八頻率時,則第十六頻率與第十八頻率兩者的信號強度可以為六比四,同樣可以表示發信器1000所受壓力程度為60%。As mentioned in the previous paragraph, when multiple frequencies are used to represent a transmitter operating state with a multivariate state, the signal strength of each frequency can be adjusted to represent the multivariate state. For example, the aforementioned fourth signaling state may correspond to the degree of pressure experienced by the transmitter 1000. For example, when the sixteenth frequency and the seventeenth frequency are mixed, the signal strength of the two may be six to four, which is used to indicate that the transmitter 1000 is subjected to a pressure of 60%. When the interference signal includes the sixteenth frequency and the eighteenth frequency is used, the signal strengths of the eighteenth frequency and the seventeenth frequency may be six to four, which may also indicate the degree of pressure applied to the transmitter 1000. It is 60%. Similarly, when the interference signal includes the seventeenth frequency and the eighteenth frequency is used, the signal strength of the sixteenth frequency and the eighteenth frequency may be six to four, which may also represent the transmitter 1000. The degree of stress is 60%.

在另一實施例中,比方是表七的第二發信器操作狀態。例如在混合第八頻率與第九頻率時,兩者的信號強度可以為六比四,用於表示發信器1000所受壓力程度為60%。假設干擾信號當中包含第八頻率與/或第九頻率,而處理模組120將電信號改為第二頻率組合時,則第十頻率與第十一頻率兩者的信號強度可以為六比四,用於表示發信器1000所受壓力程度為60%。反之,亦然。In another embodiment, such as the second transmitter operating state of Table 7. For example, when the eighth frequency and the ninth frequency are mixed, the signal strength of the two may be six to four, which is used to indicate that the transmitter 1000 is subjected to a pressure of 60%. Assuming that the eighth frequency and/or the ninth frequency are included in the interference signal, and the processing module 120 changes the electrical signal to the second frequency combination, the signal strength of the tenth frequency and the eleventh frequency may be six to four. It is used to indicate that the pressure of the transmitter 1000 is 60%. vice versa.

在表七的第五發信器操作狀態之範例中,第一頻率組合中包含有兩個頻率,可替換的第二頻率組合中包含有三個頻率。換言之,在可替換的頻率組合當中各有複數個頻率,而數量可以不相同。In the example of the fifth transmitter operating state of Table 7, the first frequency combination includes two frequencies, and the replaceable second frequency combination includes three frequencies. In other words, there are multiple frequencies in each of the alternative frequency combinations, and the numbers can be different.

為了避免互相干擾起見,在一實施例中,頻率合成模組140所有的頻率都是互不諧振,所以偵測模組170在偵測干擾信號時,所偵測的頻率都是互不諧振。在另一實施例中,至少在對應到同一個發信器操作狀態的各頻率都是互不諧振。在更一實施例中,對應到同一個發信器操作狀態的頻率組合當中之各頻率互不諧振。在某些實施例當中,頻率合成模組140與偵測模組170可以共享頻率產生源,但本發明並不限定偵測模組170可以偵測頻率合成模組140的所有頻率。偵測模組170可以偵測頻率合成模組140的部分頻率。In order to avoid mutual interference, in an embodiment, all frequencies of the frequency synthesizing module 140 are mutually non-resonant, so when the detecting module 170 detects the interfering signal, the detected frequencies are mutually non-resonant. . In another embodiment, at least the frequencies corresponding to the same transmitter operating state are mutually non-resonant. In a further embodiment, each of the frequency combinations corresponding to the same transmitter operating state does not resonate with each other. In some embodiments, the frequency synthesizing module 140 and the detecting module 170 can share the frequency generating source. However, the present invention does not limit the detecting module 170 to detect all frequencies of the frequency synthesizing module 140. The detection module 170 can detect a part of the frequency of the frequency synthesis module 140.

在一實施例中,該偵測模組170可以如第四圖所示,包含一接收器類比前端與一解調變器。該解調變器可以如第五圖、第六圖、或第七圖所示的實施例。如前所述,該解調變器之信號產生器可以和頻率合成模組140共用。本發明並不限定該解調變器於上述實施例當中,只要能夠偵測接收信號當中,是否有某一頻率的干擾信號,其干擾信號強度大於某一門檻值,處理模組120即認為干擾信號中包含該頻率。In an embodiment, the detection module 170 can include a receiver analog front end and a demodulation transformer as shown in the fourth figure. The demodulation transformer can be as shown in the fifth, sixth or seventh embodiment. As previously mentioned, the signal generator of the demodulation transformer can be shared with the frequency synthesis module 140. The present invention does not limit the demodulator in the above embodiment. As long as it can detect whether there is an interference signal of a certain frequency among the received signals, and the interference signal strength is greater than a certain threshold value, the processing module 120 considers the interference. This frequency is included in the signal.

在一實施例中,該偵測模組170用於偵測干擾信號的方式與觸控裝置的方式相同,以便獲得相同的結果。比方說,當觸控裝置使用第五圖的類比解調變器時,該偵測模組170也使用第五圖的類比解調變器。類似地,當觸控裝置使用第六圖的數位解調變器時,該偵測模組170也使用第六圖的數位解調變器。當觸控裝置使用第七圖的數位解調變器時,該偵測模組170也使用第七圖的數位解調變器。但本發明並不限定在觸控系統300當中的發信器1000與觸控裝置必須使用相同的偵測方式。在另一實施例中,當觸控裝置使用第五圖的類比解調變器時,該偵測模組170使用第六圖 的數位解調變器。值得一提的是,觸控裝置是在該發信模組140發送該電信號的時候,偵測該電信號。而偵測模組170是在該發信模組140不發送該電信號的時候,偵測該接收信號當中的干擾信號。In one embodiment, the detection module 170 is configured to detect interference signals in the same manner as the touch device in order to obtain the same result. For example, when the touch device uses the analog demodulation device of the fifth figure, the detection module 170 also uses the analog demodulation device of the fifth figure. Similarly, when the touch device uses the digital demodulator of the sixth figure, the detection module 170 also uses the digital demodulator of the sixth figure. When the touch device uses the digital demodulator of the seventh figure, the detection module 170 also uses the digital demodulator of the seventh figure. However, the present invention is not limited to the same detection mode that the transmitter 1000 and the touch device in the touch system 300 must use. In another embodiment, when the touch device uses the analog demodulator of the fifth figure, the detection module 170 uses the sixth figure. Digital demodulation transformer. It is worth mentioning that the touch device detects the electrical signal when the transmitting module 140 transmits the electrical signal. The detecting module 170 detects an interference signal in the received signal when the transmitting module 140 does not transmit the electrical signal.

假設在可用頻率(組合)有限的情況下,更換頻率的選項可能是有限的時候,如何選擇被更換的頻率有以下的幾種可能。首先,當該電信號包含一第一頻率組合,其中包含複數個第一頻率,且該接收信號中包含複數個第一頻率的干擾信號時,可以先更換複數個第一頻率當中的干擾信號強度最大者。再者,可以先更換複數個第一頻率當中的加權值最大者。或者是,可以先按照一預定順序更換複數個第一頻率當中的順序最前者。Assuming that the available frequency (combination) is limited, the option to change the frequency may be limited.

First, when the electrical signal includes a first frequency combination including a plurality of first frequencies, and the received signal includes a plurality of interference signals of the first frequency, the interference signal strength among the plurality of first frequencies may be replaced first. The biggest one. Furthermore, the largest of the plurality of first frequencies can be replaced first. Alternatively, the order of the plurality of first frequencies may be replaced first in a predetermined order.
