Description
本發明係關於一種觸控筆，尤其係一種用來操作電容式觸控裝置之觸控筆。The invention relates to a stylus, in particular to a stylus for operating a capacitive touch device.
隨著科技的進步，電子產品的功能性不斷提升，且更加以追求便利為主要訴求，因此，電子周邊技術中亦追尋提高人機介面之使用效率，而其中，觸控技術即為一項具有高度人性化之人機介面技術。目前，觸控技術係廣泛地應用於全球定位系統(Global Positioning System)、個人數位助理(Personal Digital Asistant)、行動電話(Cellular Phone)、掌上型電腦(Palm-Size PC)及資訊家電(Information Appliance)等電子產品。而此類電子產品的顯示螢幕上皆建置有一觸控面板，供使用者觸控操作。With the advancement of technology, the functionality of electronic products continues to increase, and the pursuit of convenience is the main demand. Therefore, electronic peripheral technology also pursues the use efficiency of human-machine interface. Among them, touch technology is one. Highly humanized human interface technology. Currently, touch technology is widely used in Global Positioning System, Personal Digital Asistant, Cellular Phone, Palm-Size PC, and Information Appliance. ) and other electronic products. A touch panel is built on the display screen of such an electronic product for the user to touch.
目前的觸控面板的主流為電容式觸控面板，為了提高使用者之操作便利性，多半電容式觸控面板係可搭配一觸控筆以作為點擊輸入或是於觸控面板上書寫或畫圖等輸入動作。The current mainstream of touch panels is a capacitive touch panel. In order to improve the user's convenience, most capacitive touch panels can be used with a stylus as a click input or written or drawn on the touch panel. Wait for input actions.
一般而言，觸控筆有兩種作用方式，一種是藉由導體的原理，利用人體微弱的漏電流流經觸控筆，以改變觸控面板表面電容的電位，或是改變投射式電容的電場。另一種是觸控筆本身設計有可以感應的電場，可以改變投射式電容的電場，或是本身有內建電容和放電迴路，以改變表面電容的電位。而電容式觸控面板便可根據其變化推算出其被接觸的座標位置。Generally speaking, the stylus has two modes of action. One is to use the principle of a conductor to use a weak leakage current of the human body to flow through the stylus to change the potential of the surface of the touch panel, or to change the projected capacitance. electric field. The other is that the stylus itself is designed with an electric field that can be sensed, can change the electric field of the projected capacitor, or has its own built-in capacitor and discharge loop to change the potential of the surface capacitor. The capacitive touch panel can calculate the position of the contact to be touched according to the change.
然而，習知使用觸控筆操控電容式觸控面板時，一般觸控筆只可使電容式觸控面板具有單一功能，例如只能點擊、畫畫、改變字型等等功能中選擇其中之一而已，當使用者欲使電容式觸控面板具有不同的觸控功能時，例如改變觸控筆書寫時的線條顏色或線條的粗細等，習知的作法是以觸控筆點選電容式觸控面板上的功能選擇虛擬鍵，以改變其輸入功能，如此，將造成使用者操作上的不方便。However, when using a stylus to manipulate a capacitive touch panel, a general stylus can only have a single function of the capacitive touch panel, such as a function of only clicking, drawing, changing a font, and the like. Once the user wants to make the capacitive touch panel have different touch functions, such as changing the color of the line or the thickness of the line when the stylus is written, the conventional method is to select the capacitive type by the stylus. The function on the touch panel selects a virtual key to change its input function, which will cause inconvenience to the user.

The frequency generating circuit 222 can generate the first frequency signal F1 or the second frequency signal F2 by using the first resistor element R1 or the second resistor element R2, so that the signal generating circuit 223 generates the first touch signal T1 or the second touch. The control signal T2, and the first touch signal T1 or the second touch signal T2 can change the leakage current of the touch panel 31. Therefore, the touch panel 31 can calculate the touch panel 31 according to the change of the leakage current. The position of the coordinates being touched and its function. The first touch signal T1 can, for example, enable the stylus 2 to have a first function of writing, and the second touch signal T2 can, for example, cause the stylus 2 to have a second function of erasing. Of course, the capacitive touch device can also detect and determine the first touch signal T1 or the second touch signal T2 and its touch position to control the function of writing or erasing.

However, in other implementations, the switching element W can also be a push button switch and is disposed, for example, on the second end 44 or the first end 43 of the stylus pen 4.
觸控筆4的使用者可藉由切換元件W的轉動切換，以選擇第一電阻元件R1或第二電阻元件R2來與頻率產生電路422導通而分別產生第一頻率訊號F1或第二頻率訊號F2。值得一提的是，也可藉由切換元件W選擇不同的材料(不同的材料可具有不同的電阻值)，一樣可控制頻率產生電路422產生不同的頻率訊號。The user of the stylus 4 can switch between the rotation of the switching element W to select the first resistive element R1 or the second resistive element R2 to be electrically connected to the frequency generating circuit 422 to generate the first frequency signal F1 or the second frequency signal respectively. F2. It is worth mentioning that the switching element W can also select different materials (different materials can have different resistance values), and the frequency generating circuit 422 can be controlled to generate different frequency signals.
另外，本實施例之本體41係為一絕緣體，而絕緣體可隔絕使用者身上的電容(或是雜散電容)，以避免使用者握持觸控筆4之本體41時干擾觸控筆4輸出之觸控訊號而影響其功能。In addition, the body 41 of the embodiment is an insulator, and the insulator can isolate the capacitance (or stray capacitance) of the user body, so as to prevent the user from interfering with the output of the stylus 4 when the user holds the body 41 of the stylus pen 4. The touch signal affects its function.
此外，觸控筆4的其它技術特徵可參照觸控筆2，於此不再贅述。In addition, other technical features of the stylus 4 can be referred to the stylus pen 2, and details are not described herein again.
因此，當觸控筆4觸控電容式觸控面板51前，使用者可藉由切換開關W的切換，選擇開關選擇電路421之不同電阻元件(或不同材料)，而當觸控筆4接觸電容式觸控面板51時，訊號產生電路423可產生對應之觸控訊號，並使電容式觸控面板51具有對應的功能。另外，要更改其功能時，只要使用切換開關W選擇其它的電阻元件(或材料)，則訊號產生電路423可產生對應之另一觸控訊號，並使電容式觸控面板51具有另一對應的功能。Therefore, before the stylus 4 touches the capacitive touch panel 51, the user can select different resistance elements (or different materials) of the switch selection circuit 421 by switching the switch W, and when the stylus 4 contacts In the capacitive touch panel 51, the signal generating circuit 423 can generate a corresponding touch signal, and the capacitive touch panel 51 has a corresponding function. In addition, when the function is to be changed, the signal generating circuit 423 can generate another corresponding touch signal by using the switch W to select another resistive element (or material), and the capacitive touch panel 51 has another corresponding The function.
綜上所述，因依據本發明之觸控筆的控制模組包含一開關選擇電路、一頻率產生電路及一訊號產生電路，而頻率產生電路可依據開關選擇電路的選擇而產生一第一頻率訊號及一第二頻率訊號，訊號產生電路可依據第一頻率訊號及第二頻率訊號產生一第一觸控訊號及一第二觸控訊號。藉此，當觸控筆接觸電容式觸控裝置之一觸控面板時，電容式觸控裝置可依據訊號產生電路產生之第一觸控訊號及第二觸控訊號分別決定第一功能及第二功能，且第一功能及第二功能係不相同。因此，本發明之觸控筆接觸電容式觸控裝置時，相同的輸入動作，卻可使電容式觸控裝置具有不同的功能，以增加操控的便利性。In summary, the control module of the stylus according to the present invention includes a switch selection circuit, a frequency generation circuit and a signal generation circuit, and the frequency generation circuit can generate a first frequency according to the selection of the switch selection circuit. And the second frequency signal, the signal generating circuit generates a first touch signal and a second touch signal according to the first frequency signal and the second frequency signal. Therefore, when the stylus touches one of the touch panels of the capacitive touch device, the capacitive touch device can determine the first function and the first touch signal according to the first touch signal and the second touch signal generated by the signal generating circuit. Two functions, and the first function and the second function are different. Therefore, when the stylus of the present invention contacts the capacitive touch device, the same input action can make the capacitive touch device have different functions to increase the convenience of manipulation.
