第1圖為本發明第一實施例之畫面遮蔽方法100的流程圖。第2圖為適用於本發明第一實施例之顯示器的示意圖。為了說明本發明第一實施例之畫面遮蔽方法100，請同時參照第1圖與第2圖。 FIG. 1 is a flow chart of a screen masking method 100 according to a first embodiment of the present invention. Fig. 2 is a schematic view of a display suitable for use in the first embodiment of the present invention. In order to explain the screen masking method 100 of the first embodiment of the present invention, please refer to FIG. 1 and FIG. 2 simultaneously.
在第2圖中，顯示器110包含五個控制按鍵120、122、124、126以及128。另外，顯示器110的顯示面板110a包含四個顯示區域131、133、135以及137。需說明的是，顯示區域131、133、135以及137在圖中是以虛線標示。為了清楚分辨虛線，相鄰虛線間係分離一段距離，但實際上相鄰的顯示區域係為互相接觸。另外，上述控制按鍵之數目並不限定於五個，而上述顯示區域之數目亦不限定於四個。本領域之習知技藝人士可依照實際需求調整上述控制按鍵以及顯示區域之數目。 In FIG. 2, display 110 includes five control buttons 120, 122, 124, 126, and 128. In addition, the display panel 110a of the display 110 includes four display areas 131, 133, 135, and 137. It should be noted that the display areas 131, 133, 135, and 137 are indicated by broken lines in the drawing. In order to clearly distinguish the dotted lines, the adjacent dashed lines are separated by a distance, but in reality the adjacent display areas are in contact with each other. In addition, the number of the above control buttons is not limited to five, and the number of the display areas is not limited to four. Those skilled in the art can adjust the number of control buttons and display areas described above according to actual needs.
請同時參照第1圖與第2圖。為了能在顯示器110上實施本發明的畫面遮蔽方法100，於第1圖中所示的步驟102中，一初始畫面P首先顯示於顯示器110上。接著，在步驟104中，當使用者沿第一方向160連續地按壓或觸碰控制按鍵120、122、124、126以及128中至少兩個相鄰的控制按鍵時，顯示器110將順向地(呼應沿第一方向160的按壓時序)接收到至少兩個對應的相鄰控制按鍵之訊號，並隨後會針對顯示器110上至少一對應的顯示區域(例如顯示區域131、133、135以及137中其中之一者)輸出一影像資料。而影像資料會取代對應於顯示區域中部分的 初始畫面P。 Please refer to both Figure 1 and Figure 2. In order to implement the screen masking method 100 of the present invention on the display 110, in step 102 shown in FIG. 1, an initial screen P is first displayed on the display 110. Next, in step 104, when the user continuously presses or touches at least two adjacent control buttons of the control buttons 120, 122, 124, 126, and 128 in the first direction 160, the display 110 will be forward ( Receiving signals of at least two corresponding adjacent control buttons in response to the pressing sequence of the first direction 160, and then for at least one corresponding display area on the display 110 (eg, display areas 131, 133, 135, and 137) One of them outputs an image data. Image data will replace the part corresponding to the display area. Initial picture P.
承上述，若使用者連續按壓相鄰的控制按鍵120以及122後，顯示器110則對應於顯示區域131輸出影像資料Q；若使用者連續按壓相鄰的控制按鍵122以及124後，顯示器110則對應於顯示區域133輸出影像資料Q；若使用者連續按壓相鄰的控制按鍵124以及126後，顯示器110則對應於顯示區域135輸出影像資料Q；而若使用者連續按壓相鄰的控制按鍵126以及128後，顯示器110則對應於顯示區域137輸出影像資料Q。在本實施例中，由於顯示器110的控制按鍵120~128是沿著螢幕的長邊方向排列。因此，為了讓使用者能直覺地順著控制按鍵的按壓方向遮蓋或恢復螢幕上的畫面，輸出的影像資料Q之長邊係平行於顯示器110之螢幕的短邊。在其他實施例中，若顯示器的控制按鍵是沿著螢幕的短邊方向排列，輸出的影像資料之長邊將平行於顯示器之螢幕的長邊。 In the above, if the user continuously presses the adjacent control buttons 120 and 122, the display 110 outputs the image data Q corresponding to the display area 131; if the user continuously presses the adjacent control buttons 122 and 124, the display 110 corresponds to The image data Q is outputted in the display area 133; if the user continuously presses the adjacent control buttons 124 and 126, the display 110 outputs the image data Q corresponding to the display area 135; and if the user continuously presses the adjacent control button 126 and After 128, the display 110 outputs the image data Q corresponding to the display area 137. In the present embodiment, the control buttons 120 to 128 of the display 110 are arranged along the long side direction of the screen. Therefore, in order to allow the user to intuitively cover or restore the screen on the screen in the pressing direction of the control button, the long side of the output image data Q is parallel to the short side of the screen of the display 110. In other embodiments, if the control buttons of the display are arranged along the short side of the screen, the long side of the output image data will be parallel to the long side of the screen of the display.
進一步而言，當相鄰的控制按鍵120以及122被接續按壓時，顯示器110連續收到控制按鍵120以及122的訊號，並針對顯示區域131輸出一影像資料Q。而此影像資料Q則取代在顯示區域131中的部分初始畫面P。其中，影像資料Q為一包含黑色畫面的影像資料(在第2圖中以網點來表示)，以遮蔽顯示區域131中的部分初始畫面P。當然，影像資料Q也可包含足以遮蔽部分初始畫面P之其他顏色的畫面。 Further, when the adjacent control buttons 120 and 122 are successively pressed, the display 110 continuously receives the signals of the control buttons 120 and 122, and outputs an image data Q for the display area 131. This image material Q replaces part of the initial picture P in the display area 131. The image data Q is a video material including a black screen (indicated by a halftone dot in FIG. 2) to shield a part of the initial screen P in the display area 131. Of course, the image data Q may also contain a picture sufficient to mask some of the other colors of the initial picture P.
類似地，當相鄰的控制按鍵122與124、124與126、 或126與128被接續地按壓時，顯示區域133、135或137輸出影像資料Q來取代顯示區域133、135或137中的部分初始畫面P。而在特定的狀況下，當使用者沿著第一方向160接連按壓控制按鍵122至128中之每一者時，顯示器110上所顯示的整個初始畫面P會被前述多個影像資料Q所取代，並被完全遮蔽。 Similarly, when adjacent control buttons 122 and 124, 124 and 126, When 126 and 128 are successively pressed, the display area 133, 135 or 137 outputs the image material Q instead of the partial initial picture P in the display area 133, 135 or 137. In a specific situation, when the user successively presses each of the control buttons 122 to 128 in the first direction 160, the entire initial picture P displayed on the display 110 is replaced by the plurality of image data Q. And was completely obscured.
另一方面，當整個或部份初始畫面P因為被上述影像資料所取代而被遮蔽時，若使用者沿第二方向162連續地按壓或觸碰控制按鍵120、122、124、126以及128中至少兩個相鄰的控制按鍵時，顯示器110將反向地(呼應沿第二方向162的按壓時序)接收到至少兩個對應的相鄰控制按鍵之訊號，並隨後會針對顯示器110上至少一對應的顯示區域(例如顯示區域131、133、135以及137中其中之一者)停止輸出上述影像資料Q，以恢復對應於顯示區域中部分的初始畫面P。 On the other hand, when the entire or part of the initial picture P is masked by being replaced by the image data, if the user continuously presses or touches the control buttons 120, 122, 124, 126 and 128 in the second direction 162 At least two adjacent control buttons, the display 110 will receive signals of at least two corresponding adjacent control buttons in a reverse direction (corresponding to the pressing sequence in the second direction 162), and then at least one for the display 110 The corresponding display area (for example, one of the display areas 131, 133, 135, and 137) stops outputting the above-described image material Q to restore the initial picture P corresponding to the portion in the display area.
為了說明顯示器110如何在收到控制按鍵的訊號後輸出影像資料，請參照第3圖。第3圖係根據本發明一實施例，繪示如第2圖所示之顯示器110的電路方塊示意圖。為方便及清楚說明起見，第3圖是根據第2圖所示之實施例為例來作說明，但不以此為限。 In order to explain how the display 110 outputs image data after receiving the signal of the control button, please refer to FIG. FIG. 3 is a block diagram showing the circuit of the display 110 as shown in FIG. 2 according to an embodiment of the invention. For convenience and clarity of explanation, FIG. 3 is an example of the embodiment shown in FIG. 2, but is not limited thereto.
如第3圖所示，顯示器110包括顯示面板110a、背光單元110b、多個控制按鍵120~128、功能控制單元130、縮放器(scaler)140、視訊輸入介面150以及記憶體160。縮放器140電性連接顯示面板110a、背光單元110b、功能 控制單元130、視訊輸入介面150以及記憶體160。功能控制單元130電性連接多個控制按鍵120~128。另外，縮放器140內還包含螢幕選單單元(on-screen display unit；OSD unit)142與合成單元144。 As shown in FIG. 3, the display 110 includes a display panel 110a, a backlight unit 110b, a plurality of control buttons 120-128, a function control unit 130, a scaler 140, a video input interface 150, and a memory 160. The scaler 140 is electrically connected to the display panel 110a, the backlight unit 110b, and the function Control unit 130, video input interface 150, and memory 160. The function control unit 130 is electrically connected to the plurality of control buttons 120-128. In addition, the scaler 140 further includes an on-screen display unit (OSD unit) 142 and a synthesizing unit 144.
於第3圖中，縮放器140透過視訊輸入介面150接收並處理來自外部圖像處理單元190的輸入畫面訊號Ia而產生一初始畫面P。在一般狀態下，初始畫面P會先傳送至記憶體160中，待後續顯示時，再從記憶體160中讀出初始畫面P並傳送至顯示面板110a，如此可以達到緩存的功能。 In FIG. 3, the scaler 140 receives and processes the input picture signal Ia from the external image processing unit 190 through the video input interface 150 to generate an initial picture P. In the normal state, the initial picture P is first transferred to the memory 160. When the subsequent display is performed, the initial picture P is read from the memory 160 and transmitted to the display panel 110a, so that the buffer function can be achieved.
功能控制單元130用以接收控制按鍵120~128之訊號、判斷是否連續收到上述控制按鍵中任兩個相鄰控制按鍵的訊號，並確認所收到之訊號的順序(對應第一方向160的順向接收或對應第二方向的逆向接收)。為判斷是否連續收到任兩個相鄰控制按鍵的訊號，功能控制單元130中具有一計時電路(未繪示)，用以計算兩相鄰控制按鍵之訊號間的時間間隔，若時間間隔小於一閥值(threshold)，例如100毫秒，則功能控制單元130認定兩相鄰控制按鍵的訊號被連續收到。理所當然，閥值之大小可隨本領域之習知技藝人士依照實際需求加以調整。 The function control unit 130 is configured to receive the signals of the control buttons 120-128, determine whether to continuously receive the signals of any two adjacent control buttons, and confirm the sequence of the received signals (corresponding to the first direction 160) Forward reception or reverse reception in the second direction). In order to determine whether the signals of any two adjacent control buttons are continuously received, the function control unit 130 has a timing circuit (not shown) for calculating the time interval between the signals of the two adjacent control buttons, if the time interval is less than A threshold, for example 100 milliseconds, then the function control unit 130 determines that the signals of the two adjacent control buttons are continuously received. Of course, the magnitude of the threshold can be adjusted as desired by those skilled in the art in accordance with actual needs.
當功能控制單元130順向地連續收到任兩個相鄰控制按鍵的訊號後，則針對對應的顯示區域持續送出一遮蔽訊號S至縮放器140。縮放器140於收到遮蔽訊號S時，控制螢幕選單單元142針對對應的顯示區域輸出影像資料 Q至合成單元144，此時從記憶體160中所讀取出的初始畫面P也會輸入至合成單元144。經合成單元144將初始畫面P與影像資料Q合併(例如灰階值疊加、相乘等)後，合成的畫面P+Q則輸出至顯示面板110a，並顯示於顯示器110上，如第2圖所示。 After the function control unit 130 continuously receives the signals of any two adjacent control buttons, the mask signal S is continuously sent to the corresponding display area to the scaler 140. When receiving the masking signal S, the scaler 140 controls the screen menu unit 142 to output image data for the corresponding display area. Q to the synthesizing unit 144, at which time the initial picture P read from the memory 160 is also input to the synthesizing unit 144. After the initial picture P is merged with the image data Q by the synthesizing unit 144 (for example, superimposed, multiplied, etc.), the synthesized picture P+Q is output to the display panel 110a and displayed on the display 110, as shown in FIG. Shown.
當功能控制單元130逆向地連續收到任兩個相鄰控制按鍵的訊號後，則針對對應的顯示區域停止送出遮蔽訊號S至縮放器140。當縮放器140未收到針對對應的顯示區域之遮蔽訊號S時，螢幕選單單元142停止輸出針對對應的顯示區域之影像資料Q。此時，從記憶體160中所讀取出的初始畫面P直接輸出至顯示面板110a，並顯示於顯示器110上。 After the function control unit 130 continuously receives the signals of any two adjacent control buttons in reverse, the masking signal S is stopped from being sent to the scaler 140 for the corresponding display area. When the scaler 140 does not receive the masking signal S for the corresponding display area, the screen menu unit 142 stops outputting the image data Q for the corresponding display area. At this time, the initial screen P read out from the memory 160 is directly output to the display panel 110a and displayed on the display 110.
於上述實施例中，當功能控制單元130順向地連續收到任兩個相鄰控制按鍵的訊號後，係利用如第3圖所示的螢幕選單單元142針對對應的顯示區域輸出影像資料Q，並利用合成單元144將初始畫面P與影像資料Q合併後輸出至顯示面板110a，以達成遮蔽部份初始畫面P之結果。 In the above embodiment, after the function control unit 130 continuously receives the signals of any two adjacent control buttons, the screen menu unit 142 shown in FIG. 3 outputs the image data Q for the corresponding display area. The initial picture P and the image data Q are combined by the synthesizing unit 144 and output to the display panel 110a to achieve the result of masking the partial initial picture P.
於本發明另一實施例中，上述遮蔽/還原初始畫面P之操作亦可利用如第3圖所示的外部圖像處理單元190來實現。外部圖像處理單元190可為但不限於一VGA顯示晶片。於一實施例中，外部圖像處理單元190與視訊輸入介 面150間係透過高解析度多媒體介面(High Definition Multimedia Interface；HDMI)、數位視訊介面(Digital Visual Interface；DVI)、視訊圖形陣列介面(Video Graphics Array Interface；VGA Interface)...等介面電性連接。 In another embodiment of the present invention, the operation of masking/reducing the initial picture P may be implemented by the external image processing unit 190 as shown in FIG. External image processing unit 190 can be, but is not limited to, a VGA display chip. In an embodiment, the external image processing unit 190 and the video input medium 150 interfaces through high-resolution multimedia interface (HDMI), digital video interface (DVI), video graphics array interface (VGA Interface) (VGA Interface), etc. connection.
於本實施例中，縮放器140在收到功能控制單元130針對對應的顯示區域所持續送出的遮蔽訊號S時，縮放器140透過視訊輸入介面150以針對對應的顯示區域傳送一外部處理控制訊號Cr至外部圖像處理單元190。於一實施例中，外部處理控制訊號Cr係為一I2C(Inter-Integrated Circuit)控制信號。 In the embodiment, when the scaler 140 receives the masking signal S continuously sent by the function control unit 130 for the corresponding display area, the scaler 140 transmits the external processing control signal to the corresponding display area through the video input interface 150. Cr to the external image processing unit 190. In one embodiment, the external processing control signal Cr is an I 2 C (Inter-Integrated Circuit) control signal.
外部圖像處理單元190於收到外部處理控制訊號Cr時，透過視訊輸入介面150傳送一遮蔽畫面訊號(未繪示)至縮放器140。縮放器140根據遮蔽畫面訊號產生一遮蔽畫面(未繪示)，並將上述遮蔽畫面傳送至顯示面板110a顯示。其中，上述遮蔽畫面於對應的顯示區域中係輸出影像資料Q。如此一來，即可達成遮蔽部份初始畫面P之結果。 When receiving the external processing control signal Cr, the external image processing unit 190 transmits a masking signal (not shown) to the scaler 140 through the video input interface 150. The scaler 140 generates a masking screen (not shown) according to the masking screen signal, and transmits the masking screen to the display panel 110a for display. The masking screen outputs the image data Q in the corresponding display area. In this way, the result of masking part of the initial picture P can be achieved.
另一方面，當縮放器140未收到功能控制單元130所送出的遮蔽訊號S時，縮放器140停止傳送外部處理控制訊號Cr至外部圖像處理單元190。此時，外部圖像處理單元190停止輸出上述遮蔽畫面訊號至縮放器140。如此一來，即可達成還原初始畫面P之結果。 On the other hand, when the scaler 140 does not receive the masking signal S sent by the function control unit 130, the scaler 140 stops transmitting the external processing control signal Cr to the external image processing unit 190. At this time, the external image processing unit 190 stops outputting the above-described masked screen signal to the scaler 140. In this way, the result of restoring the initial picture P can be achieved.
於本發明又一實施例中，上述遮蔽/還原初始畫面P之操作亦可利用如第3圖所示的背光單元110b來實現。第4圖為本發明第三實施例之畫面遮蔽方法400的流程圖。為了說明本發明第三實施例之畫面遮蔽方法400，請同時參照第3圖與第4圖。 In still another embodiment of the present invention, the operation of the masking/reduction initial picture P may be implemented by using the backlight unit 110b as shown in FIG. 4 is a flow chart of a screen masking method 400 according to a third embodiment of the present invention. In order to explain the screen masking method 400 of the third embodiment of the present invention, please refer to FIGS. 3 and 4 simultaneously.
於第3圖中，背光單元110b包含分別對應於顯示區域131、133、135以及137的多個背光源132、134、136以及138。需說明的是，背光源132、134、136以及138在第3圖中是以虛線標示。為了清楚分辨虛線，相鄰虛線間係分離一段距離，但實際上相鄰背光源係為互相接觸。 In FIG. 3, the backlight unit 110b includes a plurality of backlights 132, 134, 136, and 138 corresponding to the display areas 131, 133, 135, and 137, respectively. It should be noted that the backlights 132, 134, 136, and 138 are indicated by broken lines in FIG. In order to clearly distinguish the dotted lines, the adjacent dashed lines are separated by a distance, but in reality the adjacent backlights are in contact with each other.
於第4圖中所示的步驟402中，提供如第3圖所示之對應顯示區域131、133、135以及137的多個背光源132、134、136以及138。 In step 402 shown in FIG. 4, a plurality of backlights 132, 134, 136, and 138 corresponding to display areas 131, 133, 135, and 137 as shown in FIG. 3 are provided.
接著，在步驟404中，背光源132、134、136以及138被開啟，使得顯示器110上之顯示區域131、133、135以及137顯示初始畫面P。 Next, in step 404, backlights 132, 134, 136, and 138 are turned on such that display areas 131, 133, 135, and 137 on display 110 display an initial picture P.
然後，於步驟406中，在順向地連續接收到控制按鍵120、122、124、126以及128中至少兩個相鄰的控制按鍵之訊號後，關閉顯示區域131、133、135以及137中一對應的顯示區域所對應的背光源，以利用一黑畫面取代上述對應的顯示區域中之部分初始畫面P。 Then, in step 406, after continuously receiving the signals of at least two adjacent control buttons of the control buttons 120, 122, 124, 126, and 128 in the forward direction, one of the display regions 131, 133, 135, and 137 is turned off. The backlight corresponding to the corresponding display area replaces part of the initial picture P in the corresponding display area by using a black screen.
進一步而言，縮放器140在收到功能控制單元130針對對應的顯示區域所持續送出的遮蔽訊號S時，縮放器140傳送一背光控制訊號CB至背光單元110b。背光單元 110b於收到背光控制訊號CB時，關閉對應的顯示區域所對應的背光源，以利用一黑畫面取代上述對應的顯示區域中之部分初始畫面P。如此一來，即可達成遮蔽部份初始畫面P之結果。 Further, when the scaler 140 receives the masking signal S continuously sent by the function control unit 130 for the corresponding display area, the scaler 140 transmits a backlight control signal C B to the backlight unit 110b. When receiving the backlight control signal C B , the backlight unit 110 b turns off the backlight corresponding to the corresponding display area to replace a part of the initial picture P in the corresponding display area by using a black screen. In this way, the result of masking part of the initial picture P can be achieved.
另一方面，當縮放器140未收到功能控制單元130所送出的遮蔽訊號S時，縮放器140停止傳送背光控制訊號CB至背光單元110b。此時，背光單元110b開啟對應的顯示區域所對應的背光源，如此一來，即可達成還原初始畫面P之結果。 On the other hand, when the scaler 140 does not receive the masking signal S sent by the function control unit 130, the scaler 140 stops transmitting the backlight control signal C B to the backlight unit 110b. At this time, the backlight unit 110b turns on the backlight corresponding to the corresponding display area, so that the result of restoring the initial picture P can be achieved.
第5圖為本發明第四實施例之畫面遮蔽方法500的流程圖。第6圖係繪示如第2圖中之顯示器110於旋轉90度之後的示意圖。第7圖係繪示顯示器110於旋轉90度之後輸出一更新影像資料的示意圖。為了說明本發明第四實施例之畫面遮蔽方法500，請同時參照第5圖、第6圖與第7圖。與第二實施例類似，於本發明第四實施例中，上述遮蔽/還原初始畫面P之操作係利用如第3圖所示的外部圖像處理單元190來實現。 FIG. 5 is a flow chart of a screen masking method 500 according to a fourth embodiment of the present invention. Fig. 6 is a schematic view showing the display 110 as shown in Fig. 2 after being rotated by 90 degrees. Figure 7 is a schematic diagram showing the display of an updated image data after the display 110 is rotated 90 degrees. In order to explain the screen masking method 500 of the fourth embodiment of the present invention, please refer to FIG. 5, FIG. 6, and FIG. Similarly to the second embodiment, in the fourth embodiment of the present invention, the operation of the above-described masking/reduction initial picture P is realized by the external image processing unit 190 as shown in FIG.
於第5圖所示之畫面遮蔽方法500的步驟504中，如第2圖所示之影像資料Q的長邊平行於顯示器110之螢幕的短邊。 In step 504 of the screen masking method 500 shown in FIG. 5, the long side of the image data Q as shown in FIG. 2 is parallel to the short side of the screen of the display 110.
為了讓使用者能正常觀看螢幕上顯示的畫面，於步驟507中，於顯示器110之螢幕被旋轉90度之後，螢幕上 顯示的畫面也對應地被旋轉90度。第6圖顯示被旋轉後的初始畫面P’與被旋轉後的影像資料Q’。第6圖中所示的顯示區域131’、133’、135’以及137’係分別對應於第2圖中所示的顯示區域131、133、135以及137。 In order to enable the user to normally view the screen displayed on the screen, in step 507, after the screen of the display 110 is rotated 90 degrees, on the screen. The displayed screen is also rotated by 90 degrees correspondingly. Fig. 6 shows the initial screen P' after being rotated and the image data Q' after being rotated. The display areas 131', 133', 135', and 137' shown in Fig. 6 correspond to the display areas 131, 133, 135, and 137 shown in Fig. 2, respectively.
為了讓使用者依舊能直覺地沿著按鍵的排列方向遮蔽被轉動後的初始畫面P’，於步驟508中，在顯示器110之螢幕被旋轉90度之後，一更新影影像資料Qr被輸出(如第7圖中所示)。 In order to allow the user to intuitively block the rotated initial picture P' along the direction of the button arrangement, in step 508, after the screen of the display 110 is rotated by 90 degrees, an updated image data Qr is output (eg, Figure 7)).
於一實施例中，第6圖中的影像資料Q’被上述對應旋轉90度後的更新影像資料Qr所取代。如第7圖所示，更新影像資料Qr所描述之影像的長邊平行於顯示器110之螢幕的短邊。 In one embodiment, the image data Q' in Fig. 6 is replaced by the updated image data Qr corresponding to the above-described rotation by 90 degrees. As shown in FIG. 7, the long side of the image described by the updated image data Qr is parallel to the short side of the screen of the display 110.
舉例來說，若螢幕被旋轉之前，影像資料Q被輸出至如第2圖所示的顯示區域131，則於螢幕如第7圖所示被旋轉90度之後，更新影像資料Qr被輸出顯示區域131a。 For example, if the image data Q is output to the display area 131 as shown in FIG. 2 before the screen is rotated, the updated image data Qr is output to the display area after the screen is rotated by 90 degrees as shown in FIG. 131a.
而螢幕被旋轉90度之後的操作如下所述。若使用者沿第三方向660連續按壓相鄰的控制按鍵128以及126，顯示器110則對應於顯示區域131a輸出更新影像資料Qr；若使用者沿第三方向660連續按壓相鄰的控制按鍵126以及124，顯示器110則對應於顯示區域133a輸出更新影像資料Qr；若使用者沿第三方向660連續按壓相鄰的控制按鍵124以及122，顯示器110則對應於顯示區域135a輸出更新影像資料Qr；而若使用者沿第三方向660連續按壓相鄰的控制按鍵122以及120，顯示器110則對應於顯示區域 137a輸出更新影像資料Qr。 The operation after the screen is rotated by 90 degrees is as follows. If the user continuously presses the adjacent control buttons 128 and 126 in the third direction 660, the display 110 outputs the updated image data Qr corresponding to the display area 131a; if the user continuously presses the adjacent control button 126 in the third direction 660 and 124, the display 110 outputs the updated image data Qr corresponding to the display area 133a; if the user continuously presses the adjacent control buttons 124 and 122 in the third direction 660, the display 110 outputs the updated image data Qr corresponding to the display area 135a; If the user continuously presses the adjacent control buttons 122 and 120 in the third direction 660, the display 110 corresponds to the display area. 137a outputs updated image data Qr.
另一方面，當整個或部份被對應旋轉後的初始畫面P’因為被上述更新影像資料Qr所取代而被遮蔽時，若使用者沿第四方向662連續地按壓或觸碰控制按鍵120、122、124、126以及128中至少兩個相鄰的控制按鍵時，顯示器110將會針對顯示器110上至少一對應的顯示區域(例如顯示區域131a、133a、135a以及137a中其中之一者)停止輸出上述更新影像資料Qr，以恢復對應於顯示區域中部分被對應旋轉後的初始畫面P’。 On the other hand, when the entire or part of the corresponding rotated initial picture P' is blocked by the updated image data Qr, if the user continuously presses or touches the control button 120 in the fourth direction 662, When at least two adjacent control buttons 122, 124, 126, and 128 are in use, display 110 will stop for at least one corresponding display area on display 110 (eg, one of display areas 131a, 133a, 135a, and 137a) The updated image data Qr is output to restore the initial picture P' corresponding to the portion of the display area that has been rotated correspondingly.
應瞭解到，在上述實施方式中所提及的步驟，除特別敘明其順序者外，均可依實際需要調整其前後順序，甚至可同時或部分同時執行。 It should be understood that the steps mentioned in the above embodiments may be adjusted according to actual needs, and may be performed simultaneously or partially simultaneously, unless the order is specifically described.
綜上所述，本發明藉由利用設置於例如顯示器之邊框上的觸控按鍵，並偵測觸控按鍵是否接續地被致能，再利用例如螢幕選單單元或是外部圖像處理單元相應地輸出包含例如黑色的影像資料，使得螢幕上顯示之資訊可以被快速地隱藏。如此一來，可方便快速地保障使用者之隱私資料。另外，使用者僅需反向地致能觸控按鍵，即可快速地還原顯示畫面。上述觸控按鍵可整合於顯示器邊框上原有之用以調整顯示器設定(例如：亮度、對比、色溫、開關...等)之按鍵，不會佔據額外的空間，並可節省生產成本。 In summary, the present invention utilizes a touch button disposed on a frame of, for example, a display, and detects whether the touch button is continuously enabled, and then uses, for example, a screen menu unit or an external image processing unit. The output contains image data such as black so that the information displayed on the screen can be quickly hidden. In this way, the user's privacy information can be conveniently and quickly protected. In addition, the user can quickly restore the display screen by simply enabling the touch button in the reverse direction. The above-mentioned touch buttons can be integrated into the original buttons on the display frame to adjust the display settings (for example, brightness, contrast, color temperature, switch, etc.) without occupying extra space and saving production costs.
