Description

觸控處理裝置及其方法 Touch processing device and method thereof

本發明係關於適用於觸控處理裝置，特別係關於可發送複數個偵測影像之觸控處理裝置。 The present invention relates to a touch processing device, and more particularly to a touch processing device that can transmit a plurality of detected images.

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。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。 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. 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.

由於觸控螢幕上會同時存在筆尖、手指、手掌或其他物體，因此觸控處理裝置可能需要應用多種感測方式來對同一個觸控面板/螢幕加以感測，以便能夠分辨出近接在觸控面板/螢幕上的各式物件。 Since the touch screen may have a pen tip, a finger, a palm or other objects at the same time, the touch processing device may need to apply a plurality of sensing methods to sense the same touch panel/screen so as to be able to distinguish the proximity touch. Various objects on the panel/screen.

總上所述，市場上需要一種能夠提供觸控筆之相關感測資訊的同時，還能夠傳送電容式偵測之感測資訊的觸控處理裝置。使得接收端能夠對同一觸控面板所產生的多種影像來進行後續處理。 In general, there is a need in the market for a touch processing device that can provide sensing information related to a stylus while transmitting capacitive sensing information. The receiving end can perform subsequent processing on various images generated by the same touch panel.

在一實施例中，本發明提供一種觸控處理裝置，用於連接至包含多個感測點的一觸控面板。該觸控處理裝置包含一發信器偵測模組以及一資訊傳送模組。發信器偵測模組用於偵測靠近或接觸該觸控面板才發出一電信號的一發信器，並產生至少一貳維度感測資訊，其中該至少一貳維度感測資訊係對應至至少一頻率的多個感測點之感測資訊。資訊傳送模組，用於傳送該至少一貳維度感測資訊。 In one embodiment, the present invention provides a touch processing device for connecting to a touch panel including a plurality of sensing points. The touch processing device includes a transmitter detection module and an information transmission module.

The information transmission module is configured to transmit the at least one dimension sensing information.

在另一實施例中，本發明提供一種觸控處理方法，適用於連接至包含多個感測點的一觸控面板之一觸控處理裝置。該方法包含偵測靠近或接觸該觸控面板才發出一電信號的一發信器，並產生至少一貳維度感測資訊，其中該至少一貳維度感測資訊係對應至至少一頻率的多個感測點之感測資訊；以及傳送該至少一貳維度感測資訊。 In another embodiment, the present invention provides a touch processing method suitable for connecting to a touch processing device of a touch panel including a plurality of sensing points.

總上所述，本發明的主要精神之一，在於觸控處理裝置能夠提供相應於各頻率的感測資訊以及可選的電容式感測資訊，令接收端能夠利用同一觸控面板所產生的多種影像來進行後續處理。 In summary, one of the main spirits of the present invention is that the touch processing device can provide sensing information corresponding to each frequency and optional capacitive sensing information, so that the receiving end can be generated by using the same touch panel.

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 sizes, and the ratio of certain dimensions or other related scales may be highlighted. It is exaggerated to come out, and the irrelevant details are not completely drawn, in order to simplify the illustration.

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, a sensor module 130, a frequency synthesizing module 140, a signal amplifying module 150, and a signaling 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 opening and closing the call The power of the device 100.

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。在一實施例中，該充電電路可以包含在電力管理單元當中，用於保護可充電電池的過度放電與過度充電。 The power module 110 can include circuitry related to power supply and control, such as Such as battery packs, DC-to-DC voltage conversion circuits, and power management units. 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 an embodiment, the charging circuit may be included in the power management unit for protecting the overdischarge and overcharge 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，據而產生一發信器狀態。 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 state.

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 each frequency from each other The situation of interference.

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. A person skilled in the art can understand that although the frequency synthesis module 140 can be used to generate and mix multiple frequencies, the processing module 120 may also synthesize the frequency according to the state of each sensor of the sensor module 130. Module 140 produces a single frequency that is not mixed with other frequencies.

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 signal strength of a certain frequency can be utilized as a mixed The ratio of signal strength to correspond to the multi-state of a 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. The gain of the amplifier. 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。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。 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. 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 one embodiment, the intensity of the mixed signal can be used to represent the magnitude of the pressure experienced by the pressure sensor, and the state of the knob is represented by the ratio of the signal strengths of the two frequencies in the mixed signal.

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狀態。請參照表一所示，其為根據本發明一實施例的發信器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 states. For example, when n is equal to three, eight states can be modulated by the frequency of the signal. Referring to Table 1, it is a representation of the 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。比方說第一發信器狀態可以和其他的發信器狀態對調，如第七發信器狀態。 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. These three sensors The states are all binary states, so there are eight sender states combined, as shown in Table 1. It will be understood by those skilled in the art that the above-mentioned transmitter state and each sensor state can be arbitrarily changed positions. For example, the first sender state can be reversed with other transmitter states, such as the seventh transmitter state.

請參考表二所示，其為根據本發明一實施例的發信器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。比方說第一發信器狀態可以和其他的發信器狀態對調，如第八發信器狀態。 Please refer to Table 2, which is a representation of the 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 sender state can be mapped to each frequency. As shown in Table 2. It will be understood by those skilled in the art that the above-mentioned transmitter state and each sensor state can be arbitrarily changed positions. For example, the first sender state can be reversed with other transmitter states, such as the eighth transmitter 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, when the pressure sensor sensor of the pen tip does not feel the pressure, the transmitter 100 does not mix the frequency and does not emit signal. Referring to Table 2, this state is the seventh sender 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狀態，只能稱為發信器頻率狀態。此實施例的發信器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 sender state and can only be called the sender frequency state. The modulation factor of the transmitter 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 transmitter state and each frequency and signal strength according to an embodiment of the present 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狀態。以及在步驟220當中，根據該發信器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 schematic flowchart of a signaling method according to an embodiment of the 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 state is the sum of the number of possible states of each of the plurality of sensors. Or in another embodiment, the transmitter status is represented as one of any combination of state representations for each of the plurality of sensors.

In an embodiment, the signal strength of the electrical signal corresponds to the sensor mode The state of the sensor with multiple states within the group. 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 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, the signal generator 610 will send a signal to the two mixers 620I and 620Q, respectively. The mixer 620I receives the cosine signal output by the signal generator 610, and the mixer 620Q receives the sinusoidal signal output by the signal generator 610.

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.

本發明提供一種觸控處理系統，用於偵測近接於一觸控裝置的一發信器。該發信器發送一電信號，該電信號係由複數個頻率混合而成。該觸控處理系統包含：該觸控裝置，包含複數個第一電極與複數個第二電極以及其重疊處所形成的複數個感測點；以及一觸控處理裝置，用於：針對每一個該第一電極與每一個該第二電極，計算其所接收之該電信號的總信號強度；以及根據所計算出之每一個該第一電極與每一個該第二電極所接收之該電信號的總信號強度，計算該發信器與該觸控裝置的一相對位置。 The present invention provides a touch processing system for detecting a transmitter that is closely connected to a touch device. The transmitter transmits an electrical signal that is a mixture of a plurality of frequencies. The touch processing system includes: the touch device, comprising: a plurality of first electrodes and a plurality of second electrodes; and a plurality of sensing points formed by the overlapping portions thereof; and a touch processing device, configured to: for each of the a first electrode and each of the second electrodes, calculating a total signal strength of the electrical signal received by the first electrode; and calculating, according to the calculated electrical signal received by each of the first electrode and each of the second electrodes The total signal strength is calculated as a relative position of the transmitter and the touch device.

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之該電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 a signal strength corresponding to a plurality of frequencies in the electrical signal received by the first electrode and the second electrode, thereby calculating a starter and a touch device. A relative position between them can also be pushed back by the sender status Know the state of each sensor on the transmitter. 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.

請回到第三圖，上述的觸控處理裝置330與主機340之間可以採用多種形式的匯流排或實體連線。比方說，採用PCI-Express、HyperTransport、SLI、或CrossFire等高速匯流排。或者是採用較為低速的USB、I2C、或SPI等傳輸介面。此外，兩者間也可以採用共用記憶體(shared memory)的模式來傳遞資訊。本發明並不限定兩者之間的連接型式，只要其所傳遞的訊息係有關於觸控方面的訊息。 Returning to the third figure, various forms of bus bars or physical connections may be used between the touch processing device 330 and the host 340. For example, use high-speed busbars such as PCI-Express, HyperTransport, SLI, or CrossFire. Or use a relatively low-speed USB, I 2 C, or SPI transmission interface. In addition, the shared memory mode can also be used to transfer information between the two. The invention does not limit the connection between the two, as long as the message transmitted is related to the touch information.

在一實施例當中，所傳遞的訊息可以包含發信器100與觸控面板320的相對位置與發信器狀態。主機340可以不管該觸控處理裝置330如何計算該相對位置與發信狀態，此實施例比較適合用於較低速的匯流排。在另外的實施例中，觸控處理裝置330可能只進行觸控信號的偵測與收集，而將較高階的功能放在主機340來執行。如此一來，就可以降低觸控處理裝置330的成本，而且還能充分利用主機340較強大的運算資源。除此之外，要更新主機340的軟體較為容易，所以可以具有較大的彈性來進行觸控功能的修改、修正、更新、以及新增功能。 In an embodiment, the transmitted message may include the relative position and sender status of the sender 100 and the touch panel 320. The host 340 can calculate the relative position and the signaling state regardless of the touch processing device 330. This embodiment is more suitable for a lower speed bus. In other embodiments, the touch processing device 330 may only perform detection and collection of touch signals, and put higher-order functions on the host 340 for execution. In this way, the cost of the touch processing device 330 can be reduced, and the computing resources of the host 340 can be fully utilized. In addition, it is easier to update the software of the host 340, so it can have greater flexibility to modify, modify, update, and add functions to the touch function.

對於主機340而言，觸控面板320包含了複數個感測點，每一個感測點都是由相疊的第一電極321與第二電極322所組成。想要得知出近接事件的位置，可以藉由所有感測點的感測資訊進行計算。因此，觸控處理裝置330可以提供各種貳維度感測資訊至主機340。在一實施例中，上述 的貳維度感測資訊相應於觸控面板320上的每一個感測點。但在另一實施例中，上述的貳維度感測資訊相應於觸控面板320上的部分感測點。本發明並不限定貳維度感測資訊所對應的感測點數量，只要貳維度感測資訊相應到兩條以上的第一電極321與第二電極322即可。 For the host 340, the touch panel 320 includes a plurality of sensing points, each of which is composed of a first electrode 321 and a second electrode 322 that are stacked. To know the location of the proximity event, it can be calculated by sensing information of all the sensing points. Therefore, the touch processing device 330 can provide various kinds of dimensional sensing information to the host 340. In an embodiment, the above The 贰 dimension sensing information corresponds to each sensing point on the touch panel 320. However, in another embodiment, the above-described UI dimension sensing information corresponds to a portion of the sensing points on the touch panel 320. The present invention is not limited to the number of sensing points corresponding to the dimensional sensing information, as long as the dimensional sensing information corresponds to two or more first electrodes 321 and second electrodes 322.

在一實施例中，當觸控面板320的複數個第一電極321發出驅動信號時，該發信器100偵測到該驅動信號之後發出電信號。電信號可以被上述的解調變器所偵測，也可以被電容式偵測模組1030所偵測。如果是由解調變器進行偵測，則可以知道該電信號混合的頻率有那些，也可以知道是由哪一些第二電極322所偵測。如果是由電容式偵測模組1030所偵測，只可以知道是由哪一些第二電極322所偵測。 In an embodiment, when the plurality of first electrodes 321 of the touch panel 320 emit a driving signal, the transmitter 100 generates an electrical signal after detecting the driving signal. The electrical signal can be detected by the demodulator described above, or can be detected by the capacitive detection module 1030. If it is detected by the demodulator, it can be known that the frequency of the electrical signal is mixed, and it can be known which second electrode 322 is detected. If it is detected by the capacitive detection module 1030, it can only be known which second electrode 322 is detected.

在一互電容偵測的實施例當中，由於電容式偵測模組1030是依序令該複數個第一電極321發出驅動信號。當發信器100偵測不到某一條第一電極321發出的驅動信號時，是不會產生電信號的。因此，所有的第二電極322均偵測不到該電信號。然而，當發信器100偵測到某一條第一電極321發出的驅動信號之後，會產生電信號。因此，發信器偵測模組1010就知道該發信器100是位於該第一電極321附近；且某一些第二電極322可以偵知該電信號，發信器偵測模組1010與/或電容式偵測模組1030也知道該發信器是位於該些第二電極322附近。如此一來，單純透過複數個第二電極322所接收的信號，就可以得知該貳維度感測資訊。更進一步地說，經由同一時段內所有第二電極322所接收的信號，發信器偵測模組1010可以產生一貳維度感測資訊，且電容式偵測模組1030也可以產生一貳維度電容感測資訊。 In an embodiment of mutual capacitance detection, the capacitive sensing module 1030 sequentially causes the plurality of first electrodes 321 to emit driving signals. When the transmitter 100 does not detect the driving signal from the first electrode 321 , no electrical signal is generated. Therefore, all of the second electrodes 322 cannot detect the electrical signal. However, when the transmitter 100 detects a driving signal from a certain first electrode 321, an electrical signal is generated. Therefore, the transmitter detection module 1010 knows that the transmitter 100 is located near the first electrode 321; and some of the second electrodes 322 can detect the electrical signal, and the transmitter detection module 1010 and / Or the capacitive detection module 1030 also knows that the transmitter is located near the second electrodes 322. In this way, the 贰 dimensional sensing information can be known simply by the signals received by the plurality of second electrodes 322. Further, the transmitter detection module 1010 can generate one dimensional sensing information through the signals received by all the second electrodes 322 in the same time period, and the capacitive detection module 1030 can also generate a dimension. Capacitance sensing information.

在一實施例中，貳維度感測資訊可以包含關於發信器100所 發出信號的信號強度。在另一實施例中，貳維度感測資訊可以包含發信器100所混合的複數個頻率的信號強度。比方說，發信器混合了三種頻率，因此，某一貳維度感測資訊包含了第一頻率的信號強度，另一貳維度感測資訊包含了第二頻率的信號強度，更一貳維度感測資訊則包含第三頻率的信號強度。在此實施例當中，由於主機340得知了這三種頻率的信號強度，只需要將相應於同一感測點的各個頻率的信號強度相加，就可以得知發信器100所發出信號的信號強度。 In an embodiment, the UI dimension sensing information may include information about the transmitter 100. The signal strength of the signal. In another embodiment, the 贰 dimensional sensing information may include the signal strength of the plurality of frequencies mixed by the sender 100. For example, the transmitter mixes three frequencies. Therefore, one 贰 dimension sensing information includes the signal strength of the first frequency, and the other dimension sensing information includes the signal strength of the second frequency, and a sense of dimension. The measurement information contains the signal strength of the third frequency. In this embodiment, since the host 340 knows the signal strengths of the three frequencies, it is only necessary to add the signal strengths of the respective frequencies corresponding to the same sensing point, and the signal of the signal sent by the transmitter 100 can be known. strength.

上述的貳維度感測資訊並不一定包含絕對值，也可以包含相對值。比方說傳送了第一頻率的信號強度之後，上述的貳維度感測資訊可以包含傳送第二頻率與第一頻率的信號強度的差值，以及第三頻率與第一頻率/第二頻率的信號強度的差值。或者，上述的貳維度感測資訊可以包含傳送第二頻率與第一頻率的信號強度的比值，以及第三頻率與第一頻率/第二頻率的信號強度的比值。在一實施例中，也可以先傳送總信號強度值，再分別傳送各個頻率信號所占的比例值。先前已經提到，某一些訊息的調變方式係採取某些頻率的信號強度的比值，故傳送比值可以省略主機340進行運算的步驟。當然，主機340也可以進行差值或比值的還原計算，以便獲得原來的信號強度值。 The above-described 贰-dimensional sensing information does not necessarily include an absolute value, and may also include a relative value. For example, after transmitting the signal strength of the first frequency, the 贰 dimensional sensing information may include transmitting a difference between the signal strength of the second frequency and the first frequency, and the signal of the third frequency and the first frequency/second frequency. The difference in intensity. Alternatively, the 贰 dimensional sensing information may include transmitting a ratio of a signal strength of the second frequency to the first frequency and a ratio of a signal strength of the third frequency to the first frequency/second frequency. In an embodiment, the total signal strength value may also be transmitted first, and then the proportional value of each frequency signal is separately transmitted. It has been mentioned previously that the modulation of certain messages takes the ratio of the signal strength of certain frequencies, so the transmission ratio can omit the step of the host 340 performing the operation. Of course, the host 340 can also perform a reduction calculation of the difference or ratio to obtain the original signal strength value.

在一實施例中，也許觸控處理裝置330在前一次的偵測中，得知發信器100所發出的電信號混合了第一頻率與第二頻率。因此，觸控處理裝置330傳送了兩個貳維度感測資訊，第一個貳維度感測資訊對應至第一頻率，而第二個貳維度感測資訊對應至第二頻率。在後一次的偵測當中，由於發信器100內部的發信器狀態改變，所以發信器100所發出的電信號混 合了三種頻率。因此，觸控處理裝置330就必須傳送了三個貳維度感測資訊，特別是包含了第三個對應至第三頻率的貳維度感測資訊。相反地，當在後一次的偵測當中，由於發信器100內部的發信器狀態改變，所以發信器100所發出的電信號只包含單一頻率。因此，觸控處理裝置330可以只傳送了單一個貳維度感測資訊。然而，本發明並不限定觸控處理裝置330只傳送有收到頻率的相應貳維度感測資訊。在一實施例中，觸控處理裝置330可以傳送所有支援頻率的相應貳維度感測資訊，而不管發信器100是否混合了這些頻率。 In an embodiment, the touch processing device 330 may know that the electrical signal emitted by the transmitter 100 mixes the first frequency and the second frequency in the previous detection. Therefore, the touch processing device 330 transmits two pieces of dimensional sensing information, the first one-dimensional sensing information corresponding to the first frequency, and the second one-dimensional sensing information corresponding to the second frequency. In the latter detection, the electrical signal sent by the sender 100 is mixed due to the change of the transmitter state inside the sender 100. Three frequencies are combined. Therefore, the touch processing device 330 must transmit three 贰 dimensional sensing information, in particular, the third dimension sensing information corresponding to the third frequency. Conversely, in the latter detection, since the transmitter state inside the transmitter 100 changes, the electrical signal emitted by the transmitter 100 contains only a single frequency. Therefore, the touch processing device 330 can transmit only a single dimension sensing information. However, the present invention does not limit the touch processing device 330 to transmit only the corresponding dimensional sensing information of the received frequency. In an embodiment, the touch processing device 330 can transmit corresponding 贰 dimensional sensing information of all supported frequencies regardless of whether the transmitter 100 mixes the frequencies.

上述的貳維度感測資訊，可以包含多個壹維度感測資訊。在一實施例中，每一個壹維度感測資訊可以包含一軸向的全部感測點之感測資訊。在另一實施例中，一個壹維度感測資訊可以包含一軸向的部分感測點之感測資訊。比方說，當該部分感測點對應之信號強度非零時，該壹維度感測資訊紀錄非零值的感測點之位置與其信號強度，這些壹維度感測資訊可以稱之為線段(LPC,Line Piece)。換言之，上述的貳維度感測資訊，可以包含多個線段。當然該線段所包含的壹維度感測資訊也可以是零值，例如該線段所表示的是某一頻率的信號強度值與另一頻率的信號強度值的差值時，其差值可以為零。 The above-mentioned 贰 dimensional sensing information may include multiple 壹 dimensional sensing information. In an embodiment, each of the 壹 dimensional sensing information may include sensing information of all of the sensing points in an axial direction. In another embodiment, the one-dimensional sensing information may include sensing information of an axial partial sensing point. For example, when the signal intensity corresponding to the part of the sensing point is non-zero, the 壹 dimension sensing information records the position of the sensing point of the non-zero value and its signal strength, and the 壹 dimensional sensing information may be referred to as a line segment (LPC) , Line Piece). In other words, the above-described UI dimension sensing information may include a plurality of line segments. Of course, the 壹 dimensional sensing information included in the line segment may also be a zero value. For example, when the line segment represents a difference between a signal strength value of a certain frequency and a signal strength value of another frequency, the difference may be zero. .

前面已經提到，當觸控處理裝置330在傳送觸控資訊到主機340時，可以包含多個貳維度感測資訊，這些貳維度感測資訊可以分時傳送。比方說，可以先傳送關於第一橫軸上的第一頻率之信號強度，接著傳送第一橫軸上的第二頻率之信號強度。後續，再傳送第二橫軸上的第一頻率之信號強度，以及第二橫軸上的第二頻率之信號強度。以此類推，直到 傳送完所有橫軸上的第一頻率與第二頻率之信號強度為止。主機340在接收之後，可以組成兩個貳維度感測資訊。第一個貳維度感測資訊是關於所有感測點的第一頻率之信號強度，第二個貳維度感測資訊是關於所有感測點的第二頻率之信號強度。在另一個實施例中，觸控處理裝置330可以先傳送第一個貳維度感測資訊，在傳送第二個貳維度感測資訊。本發明並不限定每一個貳維度感測資訊的傳送方式。 As mentioned above, when the touch processing device 330 transmits the touch information to the host 340, it may include a plurality of 贰 dimensional sensing information, and the 贰 dimensional sensing information may be transmitted in a time-sharing manner. For example, the signal strength for the first frequency on the first horizontal axis can be transmitted first, followed by the signal strength at the second frequency on the first horizontal axis. Subsequently, the signal strength of the first frequency on the second horizontal axis and the signal strength of the second frequency on the second horizontal axis are transmitted. And so on, until The signal strengths of the first frequency and the second frequency on all horizontal axes are transmitted. After receiving, the host 340 can compose two pieces of dimensional sensing information. The first 贰 dimension sensing information is the signal strength of the first frequency of all the sensing points, and the second 贰 dimension sensing information is the signal intensity of the second frequency of all the sensing points. In another embodiment, the touch processing device 330 may first transmit the first UI dimension sensing information and transmit the second UI dimension sensing information. The present invention does not limit the manner in which each of the dimensions of the sensed information is transmitted.

透過複數個第一電極321與第二電極322，除了進行發信器100的偵測以外，觸控處理裝置330還可以進行電容式偵測。比方說，依序將第一電極321施加驅動電壓，並且測量第二電極322上的電容變化量，可以進行互電容的量測。或者，依序量測各電極的電容變化量，可以進行自電容的量測。在進行電容式量測的時候，觸控處理裝置330也可以產生一個相應於電容量測結果的貳維度電容感測資訊。這些貳維度電容感測資訊可以用於尋找在觸控面板320上近接的外部導電物體。 Through the plurality of first electrodes 321 and the second electrodes 322, in addition to detecting the transmitter 100, the touch processing device 330 can perform capacitive detection. For example, the driving voltage is applied to the first electrode 321 in sequence, and the amount of change in capacitance on the second electrode 322 is measured, and the mutual capacitance can be measured. Alternatively, the capacitance change of each electrode can be measured in sequence, and the self-capacitance measurement can be performed. During the capacitive measurement, the touch processing device 330 can also generate a 贰 dimensional capacitance sensing information corresponding to the capacitance measurement result. These 贰 dimensional capacitance sensing information can be used to find external conductive objects that are in close proximity on the touch panel 320.

在一實施例中，由於觸控處理裝置330進行發信器偵測的時間與電容式偵測的時間是錯開的，所以貳維度電容感測資訊和上述的多個貳維度感測資訊是分別傳送。然而，在另一實施例中，觸控處理裝置330可以暫存某一種貳維度感測資訊，以分時的方式傳送發信器偵測資訊與電容式感測資訊。比方說，觸控處理裝置330可以傳送關於第一橫軸上的第一頻率之信號強度，接著傳送第一橫軸上的第二頻率之信號強度，最後是傳送第一橫軸上的電容式的感測資訊。後續，再傳送第二橫軸上的第一頻率之信號強度，以及第二橫軸上的第二頻率之信號強度，最後是傳送第二橫軸上的電容式的感測資訊。以此類推，直到傳送完所有橫軸上的第一頻率與 第二頻率之信號強度以及電容式感測資訊為止。 In an embodiment, since the time that the touch processing device 330 performs the transmitter detection and the time of the capacitive detection are staggered, the 贰 dimensional capacitance sensing information and the plurality of 贰 dimensional sensing information are respectively Transfer. However, in another embodiment, the touch processing device 330 can temporarily store a certain type of sensing information and transmit the transmitter detection information and the capacitive sensing information in a time sharing manner. For example, the touch processing device 330 can transmit the signal strength with respect to the first frequency on the first horizontal axis, then transmit the signal strength of the second frequency on the first horizontal axis, and finally transmit the capacitive mode on the first horizontal axis. Sensing information. Subsequently, the signal strength of the first frequency on the second horizontal axis and the signal strength of the second frequency on the second horizontal axis are transmitted, and finally the capacitive sensing information on the second horizontal axis is transmitted. And so on, until the first frequency on all horizontal axes is transmitted The signal strength of the second frequency and the capacitive sensing information.

本發明並不限定上述的電容式感測資訊，其可能是多個壹維度感測資訊所組成的貳維度電容感測資訊，也可以是多個線段。上述的壹維度感測資訊可以是電容感應量的原始值、相鄰電極之電容感應量的差值、與/或雙差值等訊息。 The present invention does not limit the capacitive sensing information described above, and may be a plurality of dimensional capacitance sensing information composed of a plurality of dimensional sensing information, or may be a plurality of line segments. The above-mentioned 壹 dimensional sensing information may be a raw value of the capacitive sensing amount, a difference in capacitance sensing amount of adjacent electrodes, and/or a double difference value.

對於主機340來說，這些貳維度感測資訊可以認為是一張張影像。獲得各個影像的主機340可以利用各種影像處理技術來進行近接事件的偵測、近接物件的辨識與分類、近接物件的軌跡追蹤、軌跡追蹤後命令或文字之解譯等後續處理。 For the host 340, these 贰 dimensional sensing information can be considered as a single image. The host 340 that obtains each image can use various image processing technologies to perform detection of proximity events, identification and classification of proximity objects, trajectory tracking of adjacent objects, trajectory tracking commands, or interpretation of texts.
