The mobile phone is based on the user's operation. The input shows the corresponding execution result on the touch display interface. However, when a user is holding a mobile phone call, the face is usually placed close to the mobile phone, which causes the touch display interface to be easily touched. In addition, the touch display interface of mobile phones and tablets is required for the user to touch to generate effective input, and usually does not have the capability of proximity sensing. As a result, users are still unable to control mobile phones and tablets in a contactless manner.

在實施例中,控制單元根據第一電容與第二電容之總電容值變化判斷外部物體係接近或遠離顯示模組。In an embodiment, the control unit determines that the external object system is close to or away from the display module according to the total capacitance value change of the first capacitor and the second capacitor.
在實施例中,控制單元根據第一電容的電容值變化判斷外部物體的一滑移動作。例如,控制單元根據總電容值與一背景值比較以判斷接近動作的發生與否。另外,控制單元亦可根據總電容值的變化量趨勢來判斷滑移動作的發生與否或方向。In an embodiment, the control unit determines a slip movement of the external object according to the change in the capacitance value of the first capacitor. For example, the control unit compares the total capacitance value with a background value to determine whether the proximity action occurs or not. In addition, the control unit can also determine the occurrence or direction of the slip movement according to the trend of the change in the total capacitance value.

As shown in FIG. 1, the display module 1 includes a non-display area 10, a proximity sensing structure 11-13, a control unit 14, and a frame. The body 15 and a display unit 16.
近接感測結構11~13位於非顯示區10上,相鄰的近接感測結構11~13的面積相異,因而可形成不同容量的電容。另外,各近接感測結構11~13與相鄰的近接感測結構可分別具有不同的形狀,因而形成不同容量的電容。The proximity sensing structures 11 to 13 are located on the non-display area 10, and the adjacent proximity sensing structures 11 to 13 have different areas, so that capacitors of different capacities can be formed. In addition, each of the proximity sensing structures 11 to 13 and the adjacent proximity sensing structures may have different shapes, respectively, thereby forming capacitors of different capacities.
各近接感測結構11~13係作為感應電容的一端電極,分別能與一外部物體形成電容,形成的電容例如是投射式感應電容,各電容之容量係代表對應的各近接感測結構11~13與外部物體的接近程度。Each of the proximity sensing structures 11 to 13 serves as an end electrode of the sensing capacitor, and can respectively form a capacitance with an external object, and the formed capacitance is, for example, a projected sensing capacitor, and the capacity of each capacitor represents the corresponding proximity sensing structures 11 to 13 The proximity to external objects.
近接感測結構11~13設置於框體15內,其位置可靠近顯示模組1整體的一側邊,顯示單元16設置於框體15內並具有一顯示區160,非顯示區10與顯示區160不重疊,即近接感測結構11不會遮住顯示區160,使用者可直接看到顯示區160,因此,獨立設置的近接感測結構11不會妨礙顯示單元16供使用者觀看或操作。The proximity sensing structures 11 to 13 are disposed in the frame 15 at a position close to one side of the entire display module 1. The display unit 16 is disposed in the frame 15 and has a display area 160, the non-display area 10 and the display. The area 160 does not overlap, that is, the proximity sensing structure 11 does not cover the display area 160, and the user can directly see the display area 160. Therefore, the independently disposed proximity sensing structure 11 does not hinder the display unit 16 from being viewed by the user or operating.
控制單元14電性連接近接感測結構11~13以偵測電容值,藉以判斷是否有外部物體接近以及概略判斷外部物體接近的位置或移動方向。舉例來說,控制單元14可根據電容值判斷一接近動作或一滑移動作。例如,控制單元14根據近接感測結構11~13之總電容值與一背景值比較以判斷接近動作的發生與否,其亦可根據總電容值的變化量趨勢來判斷滑移動作的發生與否或方向。The control unit 14 is electrically connected to the proximity sensing structures 11 to 13 to detect the capacitance value, thereby determining whether there is an external object approaching and roughly determining the position or moving direction of the external object. For example, the control unit 14 can determine a proximity action or a slip motion based on the capacitance value. For example, the control unit 14 compares the total capacitance value of the proximity sensing structures 11 to 13 with a background value to determine the occurrence or absence of the proximity action, and may also determine the occurrence of the slip motion according to the trend of the change in the total capacitance value. No or direction.
顯示單元16包括一顯示面板供顯示畫面。另外,顯示單元16可包括顯示面板及一觸控面板,觸控面板設置於顯示面板上,觸控面板係受外部物體觸碰後產生輸入信號,其可以是電容式觸控面板、或電阻式觸控面板。其主要具有多個感測線路,感測線路的單位感應圖樣可以設定為菱形狀、線狀等。控制單元14可電性連接觸控面板來接收輸入信號。舉例來說,單位感應圖樣的形狀若是一般常見的菱形,其尺寸大約是對角線為6mm,面積約18mm2,相較於此,近接感測結構11~13的面積可設計為大於單位感應圖樣的面積,即近接感測結構11~13設計為較觸控面板能感應到更遠的外部物體。結構上,觸控面板可採用單片外掛式結構如視窗整合式觸碰感應器(Window Integrated Sensor,WIS)之、或兩片玻璃型/多片玻璃膠膜型(Glass-Glass,GG type/Glass-Film-Film,GFF type)。The display unit 16 includes a display panel for displaying a picture. In addition, the display unit 16 can include a display panel and a touch panel. The touch panel is disposed on the display panel. The touch panel generates an input signal after being touched by an external object, and the touch panel can be a capacitive touch panel or a resistive type. Touch panel. It mainly has a plurality of sensing lines, and the unit sensing pattern of the sensing line can be set to a diamond shape, a line shape, or the like. The control unit 14 can be electrically connected to the touch panel to receive an input signal. For example, if the shape of the unit sensing pattern is a generally common diamond shape, the size is about 6 mm diagonal and the area is about 18 mm 2 . Compared with this, the area of the proximity sensing structures 11 to 13 can be designed to be larger than the unit induction. The area of the pattern, that is, the proximity sensing structures 11-13, is designed to sense external objects farther than the touch panel. Structurally, the touch panel can be a single-chip external structure such as a window integrated sensor (WIS), or two glass/multiple glass film types (Glass-Glass, GG type/ Glass-Film-Film, GFF type).
在本實施例中,近接感測結構11~13係獨立於顯示單元16,而非整合於顯示單元16的線路中。在另一實施例中,近接感測結構11~13亦可整合於顯示單元16的線路中,例如是整合於觸控面板的感應線路中,不過,近接感測結構11~13仍不會佔據顯示區160內的線路。In the present embodiment, the proximity sensing structures 11-13 are independent of the display unit 16, rather than being integrated into the circuitry of the display unit 16. In another embodiment, the proximity sensing structures 11-13 can also be integrated into the circuit of the display unit 16, for example, integrated in the sensing circuit of the touch panel, but the proximity sensing structures 11-13 still do not occupy. The lines within the area 160 are displayed.
圖2為本發明較佳實施例之一種顯示模組的近接感測結構的結構示意圖,如圖2所示,在本實施例中,近接感測結構11係成對互嵌的梳狀,近接感測結構12係實心狀,近接感測結構13係梳狀,這些近接感測結構11~13的形狀與面積皆不同,疏密的程度亦也不同,因此,相鄰的近接感測結構可設定為分別形成不同大小的電容。另外,近接感測結構的圖案形狀亦可以是螺旋狀等圖案。FIG. 2 is a schematic structural diagram of a proximity sensing structure of a display module according to a preferred embodiment of the present invention. As shown in FIG. 2, in the embodiment, the proximity sensing structure 11 is paired into a pair of comb-shaped, close-connected The sensing structure 12 is solid, and the proximity sensing structure 13 is comb-shaped. The shape and area of the proximity sensing structures 11 to 13 are different, and the degree of density is also different. Therefore, the adjacent proximity sensing structure can be Set to form capacitors of different sizes. In addition, the pattern shape of the proximity sensing structure may also be a pattern such as a spiral.
在本實施例中,各近接感測結構11~13係串聯連接,控制單元14透過線路連接近接感測結構11~13的尾端。在其他實施態樣中,近接感測結構11~13亦可彼此並聯。In the present embodiment, each of the proximity sensing structures 11 to 13 are connected in series, and the control unit 14 is connected to the tail ends of the proximity sensing structures 11 to 13 through a line. In other embodiments, the proximity sensing structures 11-13 can also be connected in parallel with one another.
圖3A與圖3B為本發明較佳實施例之一種顯示模組的近接感測結構的等效電容的示意圖,如圖3A所示,當沒有外部物體接近時,近接感測結構11~13對接地或對環境分別形成背景電容CB1~CB3。在本實施例中,各近接感測結構11~13係連接在同一端,背景電容CB1~CB3為並聯,控制單元14透過線路連接近接感測結構11~13的尾端,藉以偵測此時近接感測結構11~13形成的電容之總電容值。此時,偵測到的信號S代表的是背景電容CB1~CB3之總電容值,其可作為一基礎值供判讀是否有外部物體接近。控制單元14可根據信號S將此時的總電容值當作一背景值。FIG. 3A and FIG. 3B are schematic diagrams showing the equivalent capacitance of the proximity sensing structure of a display module according to a preferred embodiment of the present invention. As shown in FIG. 3A, when no external objects are approached, the proximity sensing structures 11 to 13 are paired. Grounding or forming a background capacitance C B1 ~ C B3 for the environment. In this embodiment, each of the proximity sensing structures 11 to 13 is connected at the same end, and the background capacitors C B1 to C B3 are connected in parallel, and the control unit 14 is connected to the tail end of the proximity sensing structures 11 to 13 through the line to detect At this time, the total capacitance value of the capacitance formed by the sensing structures 11 to 13 is closely connected. At this time, the detected signal S represents the total capacitance value of the background capacitances C B1 C C B3 , which can be used as a basic value for reading whether an external object is close. The control unit 14 can treat the total capacitance value at this time as a background value according to the signal S.
如圖3B所示,當有外部物體接近時,近接感測結構11的各近接感測結構11~13除了如圖3A形成背景電容之外,其亦對在不同位置A、B、C的外部物體分別形成感應電容CS1~CS3,此時,偵測到的信號S代表的是背景電容CB1~CB3與各感應電容CS1~CS3之總電容值。若圖3B中信號S代表的總電容值大於圖3A中信號S代表的總電容值,則可判斷出有外部物體接近。感應電容CS1~CS3之電容值因外部物件與近接感測結構11~13之距離呈反比。當外部物件越接近顯示模組1,其與近接感測結構11~13之距離亦越小,使得感應電容增大。當外部物件接近顯示模組1使得感應電容值增大到一定程度,感應電容可作為偵測外部物件接近的有效信號。外部物體在位置A、B、C時,其相對於近接感測結構11~13的距離都一樣,但個別對應形成的感應電容CS1~CS3之電容值具有不同的大小,因而可作為偵測外部物件接近哪個近接感測結構11~13的有效信號。As shown in FIG. 3B, when there is an external object approaching, each of the proximity sensing structures 11-13 of the proximity sensing structure 11 is external to the different positions A, B, and C, except that the background capacitance is formed as shown in FIG. 3A. The objects respectively form the sensing capacitors C S1 ~ C S3 . At this time, the detected signal S represents the total capacitance values of the background capacitors C B1 ~ C B3 and the respective sensing capacitors C S1 ~ C S3 . If the total capacitance value represented by the signal S in FIG. 3B is greater than the total capacitance value represented by the signal S in FIG. 3A, it can be judged that an external object is approaching. The capacitance values of the sensing capacitors C S1 ~ C S3 are inversely proportional to the distance between the external object and the proximity sensing structures 11-13. When the external object is closer to the display module 1, the distance from the proximity sensing structures 11 to 13 is also smaller, so that the sensing capacitance is increased. When the external object approaches the display module 1 so that the value of the sensing capacitance is increased to a certain extent, the sensing capacitor can be used as an effective signal for detecting the proximity of an external object. When the external objects are at positions A, B, and C, the distances are the same with respect to the proximity sensing structures 11 to 13, but the capacitance values of the respective corresponding sensing capacitors C S1 to C S3 have different sizes, and thus can be used as a detective The effective signal of the proximity sensing structures 11-13 is measured by the external object.
信號S係代表感應電容CS1~CS3與CB1~CB3之總電容值,控制單元14接收信號S並根據感應電容CS1~CS3與CB1~CB3之總電容值變化判斷外部物體係接近或遠離顯示模組1,例如控制單元14將信號S與背景值比較以判斷接近動作的發生與否。另外,控制單元14亦可根據信號S的變化量趨勢來判斷滑移動作的發生與否或方向。The signal S represents the total capacitance values of the sensing capacitors C S1 ~ C S3 and C B1 ~ C B3 , and the control unit 14 receives the signal S and judges the external value according to the total capacitance values of the sensing capacitors C S1 ~ C S3 and C B1 ~ C B3 . The object system approaches or moves away from the display module 1. For example, the control unit 14 compares the signal S with the background value to determine the occurrence or failure of the proximity action. In addition, the control unit 14 can also determine the occurrence or direction of the slip movement based on the trend of the amount of change of the signal S.
圖4A與圖4B為圖3B中電容值供偵測的一示意圖,如圖4A與圖4B所示,控制單元14可根據感應電容CS1~CS3的電容值變化判斷外部物體的一滑移動作,藉以偵測滑移動作的發生與否或方向。在圖2中能形成感應電容的電容值大小的順序為近接感測結構12>近接感測結構11>近接感測結構13,因此,受到外部物體接近而偵測到的信號S的變化若如圖4A則可得知外部物體由位置A移到位置C;若偵測到的信號S的變化如圖4B剛好與圖4A相反則可得知外部物體由位置C移到位置A。因而可判斷出滑移動作的發生與否或方向。4A and FIG. 4B are schematic diagrams showing the capacitance value of FIG. 3B for detection. As shown in FIG. 4A and FIG. 4B, the control unit 14 can determine a slip of the external object according to the change of the capacitance values of the sensing capacitors C S1 ~ C S3 . Action to detect the occurrence or direction of the slip movement. The order in which the capacitance values of the sensing capacitors can be formed in FIG. 2 is the proximity sensing structure 12> the proximity sensing structure 11> the proximity sensing structure 13, and therefore, the change of the signal S detected by the proximity of the external object is as follows. 4A shows that the external object is moved from position A to position C; if the detected signal S changes as shown in FIG. 4B as opposed to FIG. 4A, it can be seen that the external object is moved from position C to position A. Therefore, the occurrence or direction of the slip movement can be judged.

電子裝置2以行動電話的應用來說,近接感測結構21~23的偵測結果可供開/關顯示面板262的判讀之用。以及禁用觸控面板261的觸控功能。舉例來說,當行動電話僅供語音通話時,在一般情況下使用者的臉部會貼近行動電話來聆聽通話內容,因而不會繼續觀看顯示器,故可關閉觸控面板261來節省電力。故當控制單元24根據近接感測結構21~23之電容值偵測到外部物體接近電子裝置2時,控制單元24係關閉顯示面板262。For the application of the mobile device 2, the detection results of the proximity sensing structures 21-23 can be used for the interpretation of the display panel 262. And disabling the touch function of the touch panel 261. For example, when the mobile phone is only for voice call, the user's face will generally be close to the mobile phone to listen to the call content, so that the display will not continue to be viewed, so the touch panel 261 can be turned off to save power. Therefore, when the control unit 24 detects that the external object approaches the electronic device 2 according to the capacitance values of the proximity sensing structures 21 to 23, the control unit 24 turns off the display panel 262.
另外,臉部接近電子裝置2亦會容易發生誤觸,尤其是當觸控面板261採用電容式觸控面板時,通話時臉部過度貼近觸控面板261會造成電容感應。為了避免通話時使用者的臉貼近手機對觸控面板造成錯誤的輸入動作,故在通話時觸控面板的觸控輸入功能需要禁能以防止誤動作。故當控制單元24根據近接感測結構21~23之電容值偵測到外部物體接近電子裝置2時,控制單元24係將觸控面板261的觸控輸入功能禁能。In addition, the face proximity electronic device 2 is also prone to false touches. Especially when the touch panel 261 uses a capacitive touch panel, the face is excessively close to the touch panel 261 during a call, which causes capacitive sensing. In order to avoid the wrong input action of the touch panel when the user's face is close to the mobile phone during the call, the touch input function of the touch panel needs to be disabled during the call to prevent malfunction. Therefore, when the control unit 24 detects that the external object approaches the electronic device 2 according to the capacitance values of the proximity sensing structures 21 to 23, the control unit 24 disables the touch input function of the touch panel 261.
綜上所述,由於本發明之顯示模組及電子裝置中,近接感測結構內二個相鄰的電極區域係分別設定為形成不同容量的一電容,因此,利用近接感測結構可得知近距感測的結果,外部物體接近時相對於近接感測結構的位置因而測得。In summary, in the display module and the electronic device of the present invention, two adjacent electrode regions in the proximity sensing structure are respectively set to form a capacitor of different capacity, so that the proximity sensing structure can be used. As a result of the proximity sensing, the position of the external object relative to the proximity sensing structure is measured as it is approached.
