為了豐富電子設備的功能,提升使用者體驗,現有電子設備之面板上已經載入有壓力感測器,用戶在使用手指,手寫筆等在電子設備的面板上進行按壓操作時,壓力感測器可以偵測到按壓操作所對應的按壓力值。 In order to enrich the functions of the electronic device and enhance the user experience, the pressure sensor is already loaded on the panel of the existing electronic device, and the user uses a finger, a stylus, etc. to perform a pressing operation on the panel of the electronic device, the pressure sensor The pressing force value corresponding to the pressing operation can be detected.
現載入有壓力感測器的面板結構如第1A圖、第1B圖所示,面板1T包含蓋板1,蓋板1界定顯示區1a,顯示區1a用於圖像顯示;除顯示區1a外,蓋板1表面的其他區域為非顯示區1b,非顯示區1b所對應的蓋板1之異於按壓操作面的一側通常有形成遮蔽層以遮蔽不必要的光和線跡,在非顯示區1b內通常還包含一按鍵區1e,按鍵區1e內設置有機械按鍵9,當使用者按下機械按鍵9時,面板1T即執行某一特定的功能(如顯示使用者介面主功能表、關閉程式或解鎖)。蓋板1的第一表面1c(上表面)為按壓操作面,手指、手寫筆等可以在上面進行按壓操作,蓋板1的第二表面1d(下表面)由近至遠依次設置有觸控感測器2,LCD顯示模組3以及支撐結構6,觸控感測器2用於偵測按壓操作的位置。LCD顯示模組3控制顯示區1a圖像的顯示。支撐結構6與LCD顯示 模組3之間設置有一定的距離,支撐結構6靠近LCD顯示模組3的一側設置有一壓力感測元件5,支撐結構6用於支撐壓力感測元件5,壓力感測元件5採用導電材料製成,其與LCD顯示模組3之間隔有一定的距離,在LCD顯示模組3內設置有導電電極(未圖示),導電電極與壓力感測元件5構成一個或多個電容4,當用戶在蓋板1上進行按壓操作時會對蓋板1的第一表面1c施加按壓力,由於按壓力的施加,導電電極與壓力感測元件5之間的距離發生了變化,即電容4的輸出值發生了變化,不同的按壓力即對應於不同的電容4容值,藉由對電容4容值進行偵測和運算就可以獲得對應按壓操作的按壓力值。由於面板1之按壓操作的按壓力值偵測需要LCD顯示模組3內的導電電極與壓力感測元件5配合完成,故,在面板1的非顯示區域(如按鍵區1e),其沒有按壓力偵測功能。這種結構的面板1T對非顯示區1b的功能擴展產生了一定的限制。 The panel structure currently loaded with the pressure sensor is as shown in FIG. 1A and FIG. 1B, and the panel 1T includes a cover plate 1 defining a display area 1a for displaying an image; in addition to the display area 1a In addition, the other area on the surface of the cover 1 is the non-display area 1b, and the side of the cover 1 corresponding to the non-display area 1b which is different from the pressing operation surface usually forms a shielding layer to shield unnecessary light and stitches. The non-display area 1b usually further includes a button area 1e. The button area 1e is provided with a mechanical button 9. When the user presses the mechanical button 9, the panel 1T performs a specific function (such as displaying the main function of the user interface). Table, close program or unlock). The first surface 1c (upper surface) of the cover plate 1 is a pressing operation surface, and a finger, a stylus pen, or the like can be pressed on the upper surface, and the second surface 1d (lower surface) of the cover plate 1 is sequentially provided with touch from near to far.

The support structure 6 is used to support the pressure sensing component 5, and the pressure sensing component 5 is electrically conductive. The material is made to have a certain distance from the LCD display module 3, and a conductive electrode (not shown) is disposed in the LCD display module 3, and the conductive electrode and the pressure sensing element 5 constitute one or more capacitors 4 When the user performs a pressing operation on the cover 1 , a pressing force is applied to the first surface 1 c of the cover 1 , and the distance between the conductive electrode and the pressure sensing element 5 changes due to the application of the pressing force, that is, the capacitance The output value of 4 changes. Different pressing pressures correspond to different capacitances of the capacitor 4. By detecting and calculating the capacitance of the capacitor 4, the pressing value corresponding to the pressing operation can be obtained. Since the pressing force detection of the pressing operation of the panel 1 requires the conductive electrodes in the LCD display module 3 to be completed in cooperation with the pressure sensing element 5, in the non-display area of the panel 1 (such as the button area 1e), it is not pressed.

為了使本揭露的目的,技術方案及優點更加清楚明白,以下結合附圖及實施實例,對本揭露進行進一步詳細說明。應當理解,此處所描述的具體實施例僅僅用以解釋本揭露,並不用於限定本揭露。 The present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the disclosure and are not intended to limit the disclosure.
本揭露中所提及的「上」、「下」、「左」、「右」等位置詞僅指當前指定視圖的相對位置,而非絕對位置。 The position words "upper", "lower", "left", "right", etc. mentioned in this disclosure refer only to the relative position of the currently specified view, not the absolute position.
請參閱第2A圖,本揭露第一實施例面板10界定有一顯示區11a,顯示區11a用於圖像的顯示,除顯示區11a外,面板10表面的其他區域為非顯示區11b,在非顯示區11b內包含一按鍵區12,按鍵區12內設置有至少一按鍵14,使用者可以藉由按鍵14控制面板10的顯示或輸入輸出信號等。 Referring to FIG. 2A, the panel 10 of the first embodiment defines a display area 11a for displaying images. Except for the display area 11a, other areas on the surface of the panel 10 are non-display areas 11b. The display area 11b includes a button area 12, and the button area 12 is provided with at least one button 14. The user can control the display of the panel 10, input and output signals, and the like by the button 14.
請參閱第2B圖,面板10包含一蓋板11,蓋板11的第一表面11c(上表面)為按壓操作面,手指,手寫筆等可以在上面進行按壓操作,蓋板11的第二表面11d(下表面)對應於顯示區11a的區域處設置有一顯示模組15,蓋板11的第二表面11d對應於非顯示區11b的區域設置有一遮蔽層19,通常是絲印油墨或蝕刻光阻的方式形成,以遮蔽不必要的光和線跡。 Referring to FIG. 2B, the panel 10 includes a cover plate 11. The first surface 11c (upper surface) of the cover plate 11 is a pressing operation surface, and a finger, a stylus pen, or the like can be pressed thereon, and the second surface of the cover plate 11 11d (lower surface) corresponding to the display area 11a is provided with a display module 15, and the second surface 11d of the cover 11 is provided with a shielding layer 19 corresponding to the non-display area 11b, usually screen printing ink or etching photoresist The way is formed to mask unnecessary light and stitches.
按鍵14可以是貫穿蓋板11的機械按鍵,也可以是蓋板11第一表面11c形成的凸起或凹陷結構,也可以是蓋板11第一表面11c對應按鍵14處採用磨砂或啞光等製程以形成與按鍵14周邊區域不同的表 面材質,其還可以藉由蓋板11第二表面11d進行絲印油墨或蝕刻光阻以形成圖示的形式實現。作為一種較佳實施例,按鍵14的圖示可以與遮蔽層19同層設置,但採用不同顏色的油墨或光阻形成特定的圖示,以利於從蓋板11第一表面11c辨識按鍵14的圖示,或當遮蔽層19為多層油墨或光阻時,按鍵14圖示對應處油墨或光阻層數較少,以達到背光息滅時按鍵14圖示不顯示,而背光亮起時按鍵14圖示可見的效果。 The button 14 may be a mechanical button that passes through the cover 11 or a convex or concave structure formed by the first surface 11c of the cover 11. Alternatively, the first surface 11c of the cover 11 may be frosted or matte corresponding to the button 14. The process is to form a table different from the peripheral area of the button 14. The face material can also be realized by screen printing ink or etching photoresist by the second surface 11d of the cover plate 11 to form a graphic form. As a preferred embodiment, the illustration of the button 14 can be disposed in the same layer as the masking layer 19, but a particular pattern is formed using ink or photoresist of different colors to facilitate identification of the button 14 from the first surface 11c of the cover 11. As shown in the figure, or when the shielding layer 19 is a multi-layer ink or photoresist, the button 14 indicates that the corresponding ink or photoresist layer is small, so that when the backlight is off, the button 14 is not displayed, and when the backlight is lit, the button is pressed. 14 shows the visible effect.
按鍵14所對應的蓋板11之異於按壓操作面的一側還設置有至少一壓力感測電極13,在本揭露中,設置於蓋板11之異於按壓操作面的一側不僅包含直接或間接設置於蓋板11之異於按壓操作面的另一表面,還包含設置於異於蓋板11的另一基材層,並以黏膠貼合於蓋板11。至少一壓力感測電極13的位置對應於非顯示區11b內的按鍵區12。每一壓力感測電極13相對的兩端均藉由壓力感測導線(未圖示)電性連接至信號處理器(未圖示)以形成一迴路,偵測壓力感測電極13受按壓前後的電信號的變化,信號處理器根據電信號變化情況判斷對應的壓力信號。 At least one pressure sensing electrode 13 is disposed on a side of the cover plate 11 corresponding to the button 14 that is different from the pressing operation surface. In the disclosure, the side of the cover plate 11 that is different from the pressing operation surface includes not only the direct Or indirectly disposed on the other surface of the cover 11 different from the pressing operation surface, further comprising another substrate layer disposed different from the cover 11 and adhered to the cover 11 with adhesive. The position of the at least one pressure sensing electrode 13 corresponds to the button area 12 in the non-display area 11b. The opposite ends of each pressure sensing electrode 13 are electrically connected to a signal processor (not shown) through a pressure sensing wire (not shown) to form a loop, and the pressure sensing electrode 13 is detected before and after being pressed. The change of the electrical signal, the signal processor determines the corresponding pressure signal according to the change of the electrical signal.
在本實施例中,壓力感測電極13是形成於遮蔽層19下方,即異於蓋板11按壓操作面的一側,而在其他實施例中,當壓力感測電極13是由透明材料製作時,其也可以設置於蓋板11與遮蔽層19之間,為了更簡潔之描述,下文圖中將省略遮蔽層19,僅顯示按鍵14與壓力感測電極13的對應關係,如第2C圖,而本領域具有通常知識者可以明白遮蔽層19可設置於蓋板11與壓力感測電極13之間,或壓力感測電極13遠離蓋板11的一側。 In the present embodiment, the pressure sensing electrode 13 is formed under the shielding layer 19, that is, on the side opposite to the pressing operation surface of the cover plate 11, while in other embodiments, the pressure sensing electrode 13 is made of a transparent material. In the following, it may be disposed between the cover 11 and the shielding layer 19. For the sake of brevity, the shielding layer 19 will be omitted in the following figure, and only the correspondence between the button 14 and the pressure sensing electrode 13 is displayed, as shown in FIG. 2C. It will be understood by those skilled in the art that the shielding layer 19 can be disposed between the cover 11 and the pressure sensing electrode 13, or the side of the pressure sensing electrode 13 away from the cover 11.
在本揭露中,壓力感測電極13所採用的材料為壓阻材料,在對按鍵14對應的蓋板11第一表面11c進行按壓時,蓋板11受力形 變,相應引起位於蓋板11異於按壓操作面一側的壓力感測電極13產生應變,繼而產生電阻值變化,電阻值變化量大小正比於按壓力大小。壓阻材料具有如下特性:GF=(△R/R)/ε In the disclosure, the material used for the pressure sensing electrode 13 is a piezoresistive material. When the first surface 11c of the cover 11 corresponding to the button 14 is pressed, the cover 11 is forced. As a result, the pressure sensing electrode 13 located on the side of the cover plate 11 different from the pressing operation surface is strained, and then the resistance value is changed, and the magnitude of the resistance value is proportional to the pressing force. The piezoresistive material has the following characteristics: GF = (ΔR / R) / ε
GF(Gage Factor)為應變計因數,R為壓力感測電極13的初始電阻值,△R為壓力感測電極13的電阻值變化量,ε為壓力感測電極13在沿各個方向的應變數總和。 GF (Gage Factor) is a strain gauge factor, R is the initial resistance value of the pressure sensing electrode 13, ΔR is the amount of change in the resistance value of the pressure sensing electrode 13, and ε is the number of strains of the pressure sensing electrode 13 in various directions. sum.

As another embodiment: the pressure signals from the different pressure sensing electrodes 13 enable the signal processor to identify the source of the pressure signal by different modulation methods to determine the execution of different functions.
每一按鍵14可以對應設置成一種或多種功能。當按鍵14設置成一種功能(單一功能)時,具體面板10的壓力信號偵測流程如第7A圖所示:步驟S0:開始;步驟S1:信號處理器偵測壓力感測電極13;步驟S2:信號處理器判斷壓力感測電極13是否產生壓力信號;當無壓力信號產生時,繼續步驟S1,反之進入步驟S3;步驟S3:判斷壓力信號是否大於閾值Tth0,閾值Tt0h為預設值,用於判定由按壓動作是否有效,如若壓力信號值小於閾值Tth0,則認為按壓操作無效(可能是用戶無意間觸碰到了蓋板11第一表面11c),信號處理器繼續對壓力感測電極13進行偵測。反之,壓力信號大於閾值Tth0則認為用戶進行了有效按壓操作,進入步驟S4;步驟S4:執行第一功能;步驟S5:結束。 Each button 14 can be correspondingly configured as one or more functions. When the button 14 is set to a function (single function), the pressure signal detecting process of the specific panel 10 is as shown in FIG. 7A: step S0: start; step S1: the signal processor detects the pressure sensing electrode 13; step S2 The signal processor determines whether the pressure sensing electrode 13 generates a pressure signal; when no pressure signal is generated, proceeds to step S1, and vice versa to step S3; and step S3: determines whether the pressure signal is greater than a threshold value Tth0, and the threshold value Tt0h is a preset value, If it is determined whether the pressing action is valid, if the pressure signal value is less than the threshold value Tth0, the pressing operation is considered invalid (possibly the user inadvertently touches the first surface 11c of the cover 11), and the signal processor continues to perform the pressure sensing electrode 13 Detection. On the other hand, if the pressure signal is greater than the threshold Tth0, it is considered that the user has performed a valid pressing operation, and proceeds to step S4; step S4: performs the first function; and step S5: ends.
以一按鍵14為例,其設置成單一功能時,對應的第一功能可以被設置為如下任意功能:①,顯示指定介面,使用者藉由按壓按鍵14進行了有效的按壓操作時,面板10顯示指定介面,如,電子設備的作業系統主介面、搜索介面、螢幕保護裝置介面、返回上一級顯示功能表等等。②,運行設定程式,如解鎖及鎖屏、截屏、設置靜音、拍照、打開流覽器、播放機等等。 For example, when a button 14 is set as a single function, the corresponding first function can be set to any of the following functions: 1. Display a specified interface, and when the user performs an effective pressing operation by pressing the button 14, the panel 10 Display the specified interface, such as the main interface of the operating system of the electronic device, the search interface, the screen protector interface, return to the previous display menu, and so on. 2, run the settings program, such as unlock and lock screen, screen capture, set mute, take photos, open the browser, player and so on.
當按鍵14設置成多種功能時(此處以兩種功能為例來進行說明),具體面板10的壓力信號偵測流程如第7B圖所示:步驟T0:開始;步驟T1:信號處理器偵測壓力感測電極13;步驟T2:信號處理器判斷壓力感測電極13是否產生壓力信號;當無壓力信號產生是,繼續步驟T1,反之進入步驟T3;步驟T3:判斷壓力信號是否大於閾值Fth0,閾值Fth0為預設值,其用於判定由按壓動作是否有效,如若壓力信號值小於閾值Fth0,則認為按壓操作無效(可能是用戶無意間觸碰到了蓋板11上表面11c),信號處理器繼續對壓力感測電極13進行偵測。反之,壓力信號大於閾值Fth0則認為用戶進行了有效按壓操作進入步驟T4;步驟T4:判斷壓力信號是否大於閾值Fth1,若壓力信號小於Fth1,即壓力信號大於Fth0而小於等於Fth1時進入步驟T51,若壓力信號大於Fth1,則進入步驟T52。 When the button 14 is set to multiple functions (here, two functions are taken as an example for description), the pressure signal detecting process of the specific panel 10 is as shown in FIG. 7B: step T0: start; step T1: signal processor detection Pressure sensing electrode 13; Step T2: The signal processor determines whether the pressure sensing electrode 13 generates a pressure signal; when no pressure signal is generated, proceeds to step T1, otherwise proceeds to step T3; and step T3: determines whether the pressure signal is greater than the threshold Fth0, The threshold Fth0 is a preset value, which is used to determine whether the pressing action is valid. If the pressure signal value is less than the threshold Fth0, the pressing operation is considered invalid (maybe the user inadvertently touches the upper surface 11c of the cover 11), the signal processor The pressure sensing electrode 13 is continuously detected. On the other hand, if the pressure signal is greater than the threshold value Fth0, the user is deemed to have performed a valid pressing operation to proceed to step T4; step T4: determining whether the pressure signal is greater than the threshold value Fth1, and if the pressure signal is less than Fth1, that is, the pressure signal is greater than Fth0 and less than or equal to Fth1, the process proceeds to step T51. If the pressure signal is greater than Fth1, the process proceeds to step T52.
步驟T51:執行第一功能;步驟T52:執行第二功能;步驟T6:結束。 Step T51: Performing the first function; Step T52: Performing the second function; Step T6: Ending.
使用者按下按鍵14進行了有效輸入後,信號處理器判定壓力信號大於Fth0而小於等於Fth1時,信號處理器判定使用者「輕按壓」了按鍵14,當壓力信號大於Fth1時,則認為用戶「重按壓」了按鍵14,當然,還可以設置更多的閾值:Fth1,Fth2......Fthn(n為正整數),Fth0<Fth1<Fth2<.....<Fth(n-1)<Fthn,相鄰兩個閾值Fth(n-1)與Fthn之間形成壓力信號區間,每一壓力信號區間可以匹配一功能。所述功能可以是①,顯示指定介面,如顯示電子設備的作業系統主介 面、搜索介面、螢幕保護裝置介面、返回上一級顯示功能表等等。②,運行設定程式,如解鎖及鎖屏、截屏、設置靜音、拍照、打開流覽器、播放機等等。 After the user presses the button 14 to perform the effective input, the signal processor determines that the pressure signal is greater than Fth0 and less than or equal to Fth1, the signal processor determines that the user "lightly presses" the button 14, and when the pressure signal is greater than Fth1, the user is considered "Re-press" button 14, of course, you can also set more thresholds: Fth1, Fth2. . . . . . Fthn (n is a positive integer), Fth0<Fth1<Fth2<. . . . . <Fth(n-1)<Fthn, a pressure signal interval is formed between two adjacent thresholds Fth(n-1) and Fthn, and each pressure signal interval can match a function. The function may be 1, displaying a specified interface, such as a display system for displaying an electronic device. Face, search interface, screen protector interface, return to the previous display menu, and more. 2, run the settings program, such as unlock and lock screen, screen capture, set mute, take photos, open the browser, player and so on.
以一設置按鍵14為例來說明如何藉由一按鍵14現實多種功能,提供但不限於以下幾種方式: Taking a set button 14 as an example to illustrate how to implement multiple functions by a button 14 is provided, but not limited to the following ways:
方式一:按鍵14對應一控制信號之信號幅值的控制,「輕按壓」狀況下,以一次改變量為A1(A1可以是具體的幅值大小或幅值比例等)的方式改變控制信號幅值,「重按壓」狀況下,以一次改變量為A2(A2可以是具體的幅值大小或幅值比例等)的方式改變控制信號幅值,A1<A2,即「重按壓」情況下,使用者改變控制信號幅值的幅度要大。具體以按鍵14設置為一音量控制鍵為例來說明,使用者藉由按鍵14可以控制電子設備音量。「輕按壓」狀況下,電子設備音量提高/降低a%(a>0,相當於A1),「重按壓」狀況下,電子設備音量提高/降低b%(b>0,相當於A2),b>a,以a=5,b=10為例,即「輕按壓」狀況下,電子設備音量提高/降低5%,「重按壓」狀況下,電子設備音量提高/降低10%,這樣用戶可以藉由按壓力度來選擇音量調節的速度,通常情況下,當使用者僅僅想要小幅度調整音量時,一般按壓操作較為輕緩,反之,需要大幅調整音量時,則習慣使用力道較重的按壓操作,這種設置方式與使用者的使用習慣相適應。所述方式中控制信號音量可以替換為螢幕顯示亮度、視頻播放進度、頁面滾動速度、拍攝鏡頭焦距、拍攝速度、圖像縮放比例等等,在所述方式下,我們可以藉由單指操作就可以完成信號控制。設置多個閾值Fth0,Fth1,Fth2......Fthn(n為正整數)時,Fth0<Fth1<Fth2<.....<Fth(n-1)<Fthn,相鄰兩個閾值Fth(n-1)與Fthn之間形成一壓力信號區間,壓力信號區間Fth0至 Fth1,Fth1至Fth2,Fth(n-1)至Fthn依次匹配功能:以幅度A1改變控制信號幅值,以幅度A2改變控制信號幅值,......以幅度An改變控制信號幅值。一般而言,壓力信號所對應的按壓力越大,設置其改變幅度也越大,即A1<A2<......<An。 Method 1: The button 14 corresponds to the control of the signal amplitude of a control signal. In the "light press" condition, the control signal amplitude is changed in such a manner that the amount of change is A1 (A1 can be a specific amplitude magnitude or amplitude ratio, etc.) Value, in the case of "heavy press", the amplitude of the control signal is changed in such a way that the amount of change is A2 (A2 can be a specific magnitude or amplitude ratio, etc.), A1 < A2, that is, in the case of "heavy press" The user changes the amplitude of the control signal to a greater extent. Specifically, the button 14 is set as a volume control button as an example to illustrate that the user can control the volume of the electronic device by using the button 14. In the "light press" condition, the volume of the electronic device is increased/decreased by a% (a>0, which is equivalent to A1), and in the case of "heavy press", the volume of the electronic device is increased/decreased by b% (b>0, equivalent to A2). b>a, taking a=5, b=10 as an example, that is, under the condition of “light press”, the volume of the electronic device is increased/decreased by 5%, and under the condition of “heavy pressing”, the volume of the electronic device is increased/decreased by 10%, so that the user The speed of the volume adjustment can be selected by pressing the force. Generally, when the user only wants to adjust the volume slightly, the pressing operation is generally gentle. On the contrary, when the volume needs to be greatly adjusted, the force is heavier. Pressing operation, this setting is adapted to the user's usage habits. In the mode, the control signal volume can be replaced by screen display brightness, video playback progress, page scrolling speed, shooting lens focal length, shooting speed, image scaling, etc., in the manner that we can operate by single finger operation Signal control can be done. Set multiple thresholds Fth0, Fth1, Fth2. . . . . . When Fthn (n is a positive integer), Fth0<Fth1<Fth2<. . . . . <Fth(n-1)<Fthn, a pressure signal interval is formed between two adjacent thresholds Fth(n-1) and Fthn, and the pressure signal interval Fth0 is Fth1, Fth1 to Fth2, Fth(n-1) to Fthn are matched in sequence: the amplitude of the control signal is changed by the amplitude A1, and the amplitude of the control signal is changed by the amplitude A2. . . . . . The amplitude of the control signal is changed by the amplitude An. In general, the larger the pressing force corresponding to the pressure signal, the larger the change amplitude is set, that is, A1 < A2 <. . . . . . <An.
方式二:按鍵14對應圖像縮放模式,在「輕按壓」狀況下,顯示區11a所顯示的介面(照片、網頁等)縮小/放大;在「重按壓」狀況下,顯示區11a所顯示的介面(照片、網頁等)放大/縮小。現有技術中電子設備在進行圖像縮放時,需要藉由設置對應功能鍵或需要雙指操作,而本揭露中所提供的面板10,用戶可以藉由單指操作完成圖像的縮放。 Method 2: The button 14 corresponds to the image zoom mode, and in the "light press" state, the interface (photo, web page, etc.) displayed in the display area 11a is reduced/enlarged; in the "repressed" state, the display area 11a is displayed.

請參閱第9圖,本揭露第三實施例面板20與第一實施例之面板10的不同之處在於:蓋板21異於按壓操作面的一側設置有一觸控電極28。觸控電極28遠離蓋板21的一側設置有顯示模組25。 Referring to FIG. 9 , the panel 20 of the third embodiment is different from the panel 10 of the first embodiment in that a cover electrode 21 is disposed on a side different from the pressing operation surface. A display module 25 is disposed on a side of the touch electrode 28 away from the cover 21 .
蓋板21與第一實施例中蓋板11相同,其同樣界定有顯示區21a和非顯示區21b,在非顯示區21b包含一按鍵區22。按鍵區22對應於蓋板21的異於操作面一側設置有一觸控電極28,觸控電極28可以選擇是否延伸至所述顯示區21a所對應的蓋板21之異於按壓操作面一側。觸控電極28用於偵測按壓操作的的位置,即手指或手寫筆等與蓋板21接觸的位置。面板20進一步包含至少一壓力感測電極23,至少一壓力感測電極23位於按鍵區22對應的蓋板21之異於按壓操作面的一側,且位於觸控電極28遠離蓋板11的一側,壓力感測電極23可以選擇是否延伸至所述顯示區21a所對應的蓋板21之異於按壓操作面一側。觸 控電極28與所述壓力感測電極23設置在同一或不同的承載體上,設置在同一承載體上的情況包含但不限定於:觸控電極28與壓力感測電極23均設置在按鍵區22對應的蓋板21之異於按壓操作面一側,或均設置在同一基材層的兩個相對的表面上。設置在不同承載體上的情況包含:觸控電極28與壓力感測電極23其中之一設置在蓋板21上,另一者設置在另設的基材層上,所述基材層藉由黏膠等貼合於蓋板21之異於按壓操作面一側,或兩者分別設置在二另設的基材層上。 The cover plate 21 is the same as the cover plate 11 of the first embodiment, and is also defined with a display area 21a and a non-display area 21b, and a non-display area 21b includes a button area 22. The touch panel 28 is disposed on the side of the cover 21 opposite to the operation surface, and the touch electrode 28 can be selected to extend to the side of the cover 21 corresponding to the display area 21a. . The touch electrode 28 is used to detect the position of the pressing operation, that is, the position of the finger or the stylus pen that is in contact with the cover 21. The panel 20 further includes at least one pressure sensing electrode 23, and the at least one pressure sensing electrode 23 is located on a side of the corresponding cover 21 of the button area 22 that is different from the pressing operation surface, and is located at a side of the touch electrode 28 away from the cover 11 On the side, the pressure sensing electrode 23 can be selected to extend to the side of the cover 21 corresponding to the display area 21a that is different from the pressing operation surface. touch The control electrode 28 and the pressure sensing electrode 23 are disposed on the same or different carrier. The case of being disposed on the same carrier includes, but is not limited to, the touch electrode 28 and the pressure sensing electrode 23 are disposed in the button area. 22 corresponding cover plates 21 are different from the side of the pressing operation surface, or are disposed on two opposite surfaces of the same substrate layer. The case of being disposed on different carriers includes: one of the touch electrodes 28 and the pressure sensing electrodes 23 is disposed on the cover plate 21, and the other is disposed on a separate substrate layer, wherein the substrate layer is The adhesive or the like is attached to the side of the cover plate 21 which is different from the pressing operation surface, or both are disposed on the two separate substrate layers.
壓力感測電極23與觸控電極28電性連接於一信號處理器(未圖示,位於一顆或多顆晶片上),信號處理器用於偵測壓力感測電極23所產生的壓力信號以確定按壓操作對應的按壓力大小,及偵測觸控電極28所產生的觸控信號以確定觸控位置所在。由於信號處理器可以根據觸控信號來確認使用者按壓操作位置,故,當按鍵區22設置有多個按鍵24時,作為一種實施方式,信號處理器可以不必確認壓力信號來自具體哪一個壓力感測電極23,其只需要偵測壓力信號大小即可,這樣可以簡化電路設計和信號處理。 The pressure sensing electrode 23 and the touch electrode 28 are electrically connected to a signal processor (not shown, located on one or more wafers), and the signal processor is configured to detect the pressure signal generated by the pressure sensing electrode 23 The pressing force corresponding to the pressing operation is determined, and the touch signal generated by the touch electrode 28 is detected to determine the touch position. Since the signal processor can confirm the user pressing the operation position according to the touch signal, when the button area 22 is provided with a plurality of buttons 24, as an embodiment, the signal processor can not confirm which pressure sense the pressure signal comes from. The measuring electrode 23 only needs to detect the magnitude of the pressure signal, which simplifies circuit design and signal processing.
按鍵區22設置有至少一按鍵24,按鍵24與壓力感測電極23的數量和位置可保持與第一實施例面板10中的實施方式一致。由於壓力感測電極23與蓋板21之間設置有觸控電極28,觸控電極28可以偵測用戶按壓操作的具體位置,故,按鍵區22的按鍵24和壓力感測電極23的對應設置方式還包含以下方式:請參閱第10A圖,按鍵區22設置一按鍵24,所述按鍵24為長條狀,壓力感測電極23數量為一個,其尺寸及週邊輪廓形狀對應於按鍵24形狀尺寸為長條狀,無論使用者按下按鍵24的左端,或右端,或中間位置,觸控電極28都可以準確的偵測出用戶的觸控位置,對應的壓力感測電極23則偵測觸控按壓操作所對 應的按壓力值。實際上,當按鍵區22對應的蓋板21與壓力感測電極23之間還設置有觸控電極28時,壓力感測電極23的數量並不限定為與按鍵24對應設置,而僅需保證與按鍵區22對應設置即可,即壓力感測電極23形狀匹配於按鍵區22形狀,尺寸等於按鍵區22尺寸。在本實施例中,因按鍵區22對應的蓋板21與壓力感測電極23之間還設置有觸控電極28,所以壓力感測電極23的尺寸也可以大於按鍵區22的尺寸。按鍵區22的按鍵24數量可以是一個或兩個或多個,如第10B圖中所示,按鍵區22a的按鍵24a之數量為2個,第10C圖中,按鍵區22b的按鍵24b之數量為3個。使用者按壓其中任意一個按鍵24b,觸控電極28偵測出用戶的觸控位置,壓力感測電極23b偵測觸控按壓操作所對應的按壓力值。如此,只需在觸控電極28遠離蓋板21側設置一長條狀的壓力感測電極23,壓力感測電極23相對的兩端各藉由壓力感測導線(未圖示)電性連接至信號處理器(未圖示)以形成迴路即可以實現按壓操作位置資訊及按壓力值的偵測,無需形成多個單獨的壓力感測電極23以一一對應於按鍵24來設置,再分別藉由兩條壓力感測導線連接至信號處理器以形成不同迴路,如此一來,採用本實施例的面板設計,可以縮減線路,提升面板20的設計空間。 The keypad 22 is provided with at least one button 24, the number and position of the button 24 and pressure sensing electrodes 23 remaining consistent with the embodiment of the panel 10 of the first embodiment. Since the touch electrode 28 is disposed between the pressure sensing electrode 23 and the cover 21, the touch electrode 28 can detect the specific position of the user's pressing operation, so the corresponding setting of the button 24 of the button area 22 and the pressure sensing electrode 23 The method further includes the following manners: Referring to FIG. 10A, the button area 22 is provided with a button 24, the button 24 is elongated, the number of the pressure sensing electrodes 23 is one, and the size and the peripheral contour shape correspond to the shape and size of the button 24. In the shape of a strip, the touch electrode 28 can accurately detect the touch position of the user regardless of whether the user presses the left end, the right end, or the middle position of the button 24, and the corresponding pressure sensing electrode 23 detects the touch. Control pressing operation The pressure value should be applied. In fact, when the touch electrode 28 is disposed between the cover 21 corresponding to the button area 22 and the pressure sensing electrode 23, the number of the pressure sensing electrodes 23 is not limited to be set corresponding to the button 24, but only needs to be guaranteed. Corresponding to the button area 22, the pressure sensing electrode 23 is shaped to match the shape of the button area 22, and the size is equal to the size of the button area 22. In this embodiment, since the touch electrode 28 is disposed between the cover 21 corresponding to the button area 22 and the pressure sensing electrode 23, the size of the pressure sensing electrode 23 may also be larger than the size of the button area 22. The number of the buttons 24 of the button area 22 may be one or two or more. As shown in FIG. 10B, the number of the buttons 24a of the button area 22a is two, and in FIG. 10C, the number of the buttons 24b of the button area 22b is It is three. When the user presses any one of the buttons 24b, the touch electrode 28 detects the touch position of the user, and the pressure sensing electrode 23b detects the pressing force value corresponding to the touch pressing operation. Therefore, only a long pressure sensing electrode 23 is disposed on the side of the touch electrode 28 away from the cover 21, and opposite ends of the pressure sensing electrode 23 are electrically connected by a pressure sensing wire (not shown). To the signal processor (not shown) to form a loop, the pressing operation position information and the pressing force value can be detected, and it is not necessary to form a plurality of individual pressure sensing electrodes 23 to be set one by one corresponding to the button 24, and then respectively The two pressure sensing wires are connected to the signal processor to form different loops. Thus, with the panel design of the embodiment, the circuit can be reduced and the design space of the panel 20 can be improved.
在本實施例中,面板20的按鍵區22同時設置有觸控電極28和壓力感測電極23,既能夠有效偵測觸控位置,又可以偵測觸控按壓力值,每一按鍵24可以對應設置成一種或多種功能,按鍵24設置成多種功能時,具體面板20的信號偵測流程如第11圖所示:步驟P0:開始;步驟P1:信號處理器偵測觸控電極28; 步驟P2:信號處理器判斷觸控電極28是否產生觸控信號;若有則進入步驟P3,否則返回步驟P1;步驟P3:存儲觸控信號;將觸控位置資訊進行存儲;步驟P4:信號處理器偵測壓力感測電極23;步驟P5:信號處理器判斷壓力感測電極23是否產生壓力信號;當無壓力信號產生時,繼續步驟P1,反之進入步驟P6;步驟P6:判斷壓力信號是否大於閾值Vth0,閾值Vth0為預設值,其用於判定由按壓動作是否有效,如若壓力信號值小於閾值Vth0,則認為按壓操作無效(可能是用戶無意間觸碰到了蓋板21的按壓操作面),進入步驟P1,信號處理器繼續對觸控電極28進行偵測。反之,壓力信號大於閾值Vth0則認為用戶進行了有效按壓操作進入步驟P7;步驟P7:判斷壓力信號是否大於閾值Vth1,若壓力信號小於Vth1,即壓力信號在Vth0而小於等於Vth1時,進入步驟P81;若壓力信號大於Vth1,進入步驟P82。 In this embodiment, the button area 22 of the panel 20 is simultaneously provided with the touch electrode 28 and the pressure sensing electrode 23, which can effectively detect the touch position and detect the touch pressing value. Each button 24 can be Corresponding to being set to one or more functions, when the button 24 is set to a plurality of functions, the signal detection process of the specific panel 20 is as shown in FIG. 11: step P0: start; step P1: the signal processor detects the touch electrode 28; Step P2: The signal processor determines whether the touch electrode 28 generates a touch signal; if yes, proceeds to step P3, otherwise returns to step P1; step P3: stores the touch signal; stores the touch position information; step P4: signal processing The device detects the pressure sensing electrode 23; step P5: the signal processor determines whether the pressure sensing electrode 23 generates a pressure signal; when no pressure signal is generated, proceeds to step P1, otherwise proceeds to step P6; and step P6: determines whether the pressure signal is greater than The threshold value Vth0 and the threshold value Vth0 are preset values for determining whether the pressing action is valid. If the pressure signal value is less than the threshold value Vth0, the pressing operation is considered invalid (maybe the user inadvertently touches the pressing operation surface of the cover plate 21) The process proceeds to step P1, and the signal processor continues to detect the touch electrode 28. On the other hand, if the pressure signal is greater than the threshold value Vth0, the user is deemed to have performed a valid pressing operation to proceed to step P7; step P7: whether the pressure signal is greater than the threshold value Vth1, and if the pressure signal is less than Vth1, that is, the pressure signal is at Vth0 and less than or equal to Vth1, the process proceeds to step P81. If the pressure signal is greater than Vth1, proceed to step P82.
步驟P81:根據觸控信號及壓力信號執行第一功能;步驟P82:根據觸控信號及壓力信號執行第二功能;步驟P9:結束。 Step P81: Perform a first function according to the touch signal and the pressure signal; Step P82: perform a second function according to the touch signal and the pressure signal; and step P9: end.
使用者按下按鍵24進行了有效輸入後,信號處理器判定壓力信號大於Vth0而小於等於Vth1時,信號處理器判定使用者「輕按壓」了按鍵24,當壓力信號大於Vth1時,則認為用戶「重按壓」了按鍵24,當然,還可以設置更多的閾值:Vth1,Vth2......Vthn(n為正整數),Vth0<Vth1<Vth2<.....<Vth(n-1)<Vthn,相鄰兩個閾值(Vth(n-1)與Vthn)之間形成一壓力信號區間,每一壓力信號區間可以匹配一功能。 After the user presses the button 24 to perform the effective input, the signal processor determines that the pressure signal is greater than Vth0 and less than or equal to Vth1, the signal processor determines that the user "lightly presses" the button 24, and when the pressure signal is greater than Vth1, the user is considered "Re-press" button 24, of course, you can also set more thresholds: Vth1, Vth2. . . . . . Vthn (n is a positive integer), Vth0<Vth1<Vth2<. . . . . <Vth(n-1)<Vthn, a pressure signal interval is formed between two adjacent thresholds (Vth(n-1) and Vthn), and each pressure signal interval can match a function.
以第10A圖中按鍵24為例來說明壓力信號偵測應用: Take the button 24 in Figure 10A as an example to illustrate the pressure signal detection application:

Similar to that described in panel 10 of the first embodiment, when the signal processor determines that the "light press" condition is determined, the "reverse"/"fast forward" amplitude of the control audio or video is small; when the signal processor determines that it is "heavy" When pressing "/", the "reverse" / "fast forward" of the control audio or video is larger.
方式二:按鍵24的「輕按壓」和「重按壓」可以分別對應於如下功能中的任意兩種的結合:顯示指定介面,如,電子設備的作業系統主介面、搜索介面、螢幕保護裝置介面、返回上一級顯示功能表等,運行設定程式,如解鎖及鎖屏、截屏、設置靜音、拍照、打開流覽器、播放機、開關機、快速撥號等。 Method 2: The "light press" and "re-press" of the button 24 can respectively correspond to the combination of any two of the following functions: display the specified interface, for example, the main interface of the operating system of the electronic device, the search interface, the screen protector interface Return to the previous level display menu, etc., run the setting program, such as unlock and lock screen, screen capture, set mute, take photos, open the browser, player, switch machine, speed dial, and so on.
