Together with the conventional display screen 41, the above power saving mode is entered. When the special display area 42 is disconnected from the conventional display screen 41, it becomes an independent display screen, and the image can be independently displayed according to its own display parameter setting. In the actual manufacturing method, a complete display screen can be manufactured as the display unit 40, and then the special display area 42 is divided therefrom by means of circuit connection during the assembly process, and the rest is used as the conventional display screen 41; It is also possible to separately manufacture two display screens corresponding to each other as the conventional display screen 41 and the special display area 42, and then combine them together and establish a connection to constitute the display unit 40.
該特殊顯示區42可用於執行一特殊顯示模式，即當行動電話於待機狀態中接收到來電、簡訊等資訊，或需要輸入操作指令(如撥出電話、編輯簡訊等)時，切斷該特殊顯示區42與該常規顯示屏41之連接，使該特殊顯示區成為獨立之顯示屏。這樣就可以僅於該特殊顯示區42內顯示電話號碼、簡訊等篇幅較小且對色彩要求 不高之圖像，同時將常規顯示屏41保持於省電模式之黑屏狀態，從而充分節省耗電量。 The special display area 42 can be used to perform a special display mode, that is, when the mobile phone receives information such as an incoming call, a short message, or the like in a standby state, or needs to input an operation instruction (such as dialing a call, editing a short message, etc.), the special is cut off. The connection of the display area 42 to the conventional display screen 41 makes the special display area an independent display. In this way, the phone number, the short message, and the like can be displayed only in the special display area 42 and the color requirement is small. The image is not high, and the conventional display screen 41 is maintained in the black screen state of the power saving mode, thereby fully saving power consumption.
請一併參閱圖3，本發明圖像顯示方法之較佳實施例即使用該顯示裝置100根據不同情況分別選擇相應之顯示模式，從而以較低之耗電量顯示圖像之方法。該方法包括以下步驟： Referring to FIG. 3 together, the preferred embodiment of the image display method of the present invention uses the display device 100 to select a corresponding display mode according to different situations, thereby displaying an image with a lower power consumption. The method includes the following steps:
提供一上述之顯示裝置100，將其安裝於行動電話等攜帶型電子裝置上供使用。 A display device 100 as described above is provided and mounted on a portable electronic device such as a mobile phone for use.
通過該顯示裝置100之操作單元10設置其不同顯示模式下之顯示參數。如前所述，該等顯示模式至少包括一使用建立有連接之該常規顯示屏41及該特殊顯示區42共同顯示同一圖像之常規顯示模式與一僅使用該特殊顯示區42顯示圖像之特殊顯示模式，該兩種顯示模式之顯示參數如背景燈光亮度、色彩、解析度等均可以分別設定。如前所述，由於常規顯示模式是使用全屏彩色模式顯示圖像，因此可以對其設定較多之色彩顯示、較高之背景燈光亮度及解析度；而特殊顯示模式是用於顯示篇幅較小且對色彩要求不高之圖像，因此可以對其設定較少之色彩顯示(甚至可以直接設置為黑白顯示)、較低之背景燈光亮度及解析度。 The display parameters in different display modes are set by the operation unit 10 of the display device 100. As described above, the display modes include at least a conventional display mode in which the conventional display screen 41 in which the connection is established and the special display area 42 collectively display the same image and an image displayed using only the special display area 42. In the special display mode, the display parameters of the two display modes, such as backlight brightness, color, resolution, etc., can be set separately. As mentioned above, since the normal display mode displays images using the full-screen color mode, it is possible to set more color display, higher background light brightness and resolution; and the special display mode is for displaying a smaller space. And the image is not required for color, so you can set less color display (even can be set directly to black and white display), lower background light brightness and resolution.
完成參數設定後，該顯示裝置100即可進入待機狀態，此時該常規顯示屏41及該特殊顯示區42保持連接並共同進入一省電模式，例如習知之黑屏省電狀態。 After the parameter setting is completed, the display device 100 can enter a standby state, at which time the conventional display screen 41 and the special display area 42 remain connected and collectively enter a power saving mode, such as a conventional black screen power saving state.
當來電、簡訊或彩信等外界資訊被該訊號接收單元30接收到時，該訊號接收單元30將該等外界資訊傳輸至該資料處理單元20。該資料處理單元20分析該資訊之種類，以確定採用何種顯示模式加 以顯示。例如，當接收到來電或簡訊時，由於來電號碼及簡訊都是篇幅較短、圖像較為簡單之文字資訊，僅需要用較小之屏幕和黑白兩色即可清晰顯示，此時即可採用特殊顯示模式。當接收到圖像較為複雜之彩信時，則需要採用常規顯示屏41及特殊顯示區42共同以彩色顯示之常規顯示模式方可完整顯示。另外，當使用者通過操作單元10對待機狀態之行動電話輸入待撥出之電話號碼、編輯簡訊或彩信、拍攝照片、瀏覽網頁等操作指令時，該操作單元10也可將操作指令傳輸至該資料處理單元20，分析該操作指令之種類以確定採用何種顯示模式加以顯示。例如，當撥打電話及編輯簡訊時，可選擇特殊顯示模式顯示撥出號碼及編輯中之簡訊等簡單圖像。當編輯彩信、拍攝照片、瀏覽網頁時，可選擇常規顯示模式顯示編輯中之彩信及預覽之照片、網頁等複雜圖像。 When external information such as an incoming call, a short message or a multimedia message is received by the signal receiving unit 30, the signal receiving unit 30 transmits the external information to the data processing unit 20. The data processing unit 20 analyzes the type of the information to determine which display mode to use. To display. For example, when an incoming call or a short message is received, since the caller number and the short message are text messages with a shorter length and a simpler image, it is only necessary to use a smaller screen and black and white to clearly display the text. Special display mode. When a multimedia message with a relatively complicated image is received, it is necessary to use a conventional display mode in which the conventional display screen 41 and the special display area 42 are collectively displayed in color to be completely displayed. In addition, when the user inputs an operation instruction such as a telephone number to be dialed, edits a text message or a multimedia message, takes a photo, browses a webpage, or the like through the operation unit 10 to the mobile phone in the standby state, the operation unit 10 can also transmit an operation instruction to the operation command. The data processing unit 20 analyzes the type of the operation command to determine which display mode is used for display. For example, when making a call and editing a text message, you can select a special display mode to display a simple image such as the dialed number and the text message being edited. When editing MMS, taking photos, and browsing web pages, you can select the regular display mode to display the MMS in the editing, the preview photos, and complex images such as web pages.
當資料處理單元20選定相應之顯示模式後，即可將接收到之來電號碼、簡訊或彩信等資訊或撥出號碼、編輯中之簡訊或彩信及預覽照片等操作指令之相關圖像傳輸至該顯示單元40進行顯示。若選定之顯示模式為特殊顯示模式，則資料處理單元20切斷該常規顯示屏41與特殊顯示區42之間之連接，使該常規顯示屏41仍然保持於省電模式之黑屏狀態以節省耗電量，同時使用該特殊顯示區42依照預定之特殊顯示模式之參數顯示相關圖像。若選定之顯示模式為常規顯示模式，則資料處理單元維持該常規顯示屏41與特殊顯示區42之間之連接，使用該常規顯示屏41與特殊顯示區42依照預定之常規顯示模式之參數顯示相關圖像。 After the data processing unit 20 selects the corresponding display mode, the related image of the received caller number, newsletter or multimedia message, or the dialed number, the edited SMS or MMS, and the preview photo can be transmitted to the image. The display unit 40 performs display. If the selected display mode is the special display mode, the data processing unit 20 cuts off the connection between the conventional display screen 41 and the special display area 42, so that the conventional display screen 41 remains in the black screen state of the power saving mode to save power. The power is simultaneously displayed using the special display area 42 in accordance with the parameters of the predetermined special display mode. If the selected display mode is the normal display mode, the data processing unit maintains the connection between the conventional display screen 41 and the special display area 42, and uses the conventional display screen 41 and the special display area 42 to display the parameters according to the predetermined normal display mode. Related images.
可以理解，上述方法中人工預設顯示參數之步驟也可以省略，由資料處理單元20於分析所接收到之資訊或輸入之指令之種類時自 動選擇適合之顯示參數即可，且資料處理單元20也可根據所選擇之顯示參數來選擇適當之顯示模式。另外，由於上述特殊顯示模式較為省電，出於節能之考慮，於實際應用中可以設置資料處理單元20首先判斷資訊或指令之圖像能否以特殊顯示模式顯示。 It can be understood that the step of manually setting the display parameters in the above method may also be omitted, and the data processing unit 20 analyzes the received information or the type of the input instruction. The selection of the appropriate display parameters can be selected, and the data processing unit 20 can also select an appropriate display mode based on the selected display parameters. In addition, since the above special display mode is more power-saving, in the practical application, the data processing unit 20 can be set to first determine whether the image of the information or the command can be displayed in the special display mode.
本發明提供之顯示裝置100及其對應之圖像顯示方法可以根據接收到之資訊或操作指令之相關圖像之性質選擇不同之顯示模式。當圖像對顯示之篇幅、色彩等方面要求較低時，可以僅使用顯示單元40中較小之特殊顯示區42對其加以顯示，而將顯示單元之其他部分即常規顯示屏41保持於省電模式。與習知技術相比，本發明可以明顯地減少耗電量，達到節能之目之。 The display device 100 and the corresponding image display method provided by the present invention can select different display modes according to the nature of the received image or the related image of the operation instruction. When the image has a lower requirement on the length, color, and the like of the display, it can be displayed using only the smaller special display area 42 of the display unit 40, while the other portion of the display unit, that is, the conventional display screen 41, is maintained in the province. Electrical mode. Compared with the prior art, the present invention can significantly reduce power consumption and achieve energy saving.
