470874 五、發明說明（i) 本發明係提供一種省電方法及裝置，尤指一種於電腦系統之螢幕中利用計時器計時以自動進入省電模式之方法及其裝置。隨著科技的發展，電腦逐漸變成人們日常生活不可或缺的一部份，因此各種電腦產品不斷推陳出新，大量生產的結果使得生產及銷售的價格降低，也連帶促使電腦的普及率愈來愈高與人們對其依賴日漸加深。在一電腦系統中，通常包含有電腦主機、螢幕以及各種輸出或輸入裝置，然而在電腦系統之各種裝置中，螢幕所消耗的電能約佔整個電腦系統的百分之五十至八十。在資源有限及環保掛帥的今日，既然電腦的使用已經變成不可避免的潮流，如何經濟有效率地使用電腦，尤其是如何使電腦系統中消耗電能最多的螢幕能降低其電能的消耗而同時亦能兼顧使用者的需求，即變成主要研討的課題。 i470874 V. Description of the invention (i) The present invention provides a method and a device for saving power, in particular a method and a device for automatically entering a power-saving mode by using a timer in a screen of a computer system to count time. With the development of technology, computers have gradually become an indispensable part of people's daily life. Therefore, various computer products have been continuously innovated. As a result of mass production, the prices of production and sales have been reduced, and the popularity of computers has been increasing. And people are increasingly dependent on it. A computer system usually includes a computer host, a screen, and various output or input devices. However, among the various devices of a computer system, the screen consumes about 50 to 80% of the entire computer system. Today, with limited resources and environmental protection, since the use of computers has become an inevitable trend, how to use computers economically and efficiently, especially how to make the screen that consumes the most power in a computer system can reduce its power consumption while also Taking into account the needs of users, that becomes the main topic of discussion. i

J | 通常在電腦系統中，是由電腦主機透過螢幕顯示卡傳 |送影像晝面信號（video signal)、水平同步信號（Hsync) 及垂直同步信號（Vsync)至螢幕以用來顯示晝面於螢幕上。為了節省電腦系統中螢幕所消耗的電能，現今最常見的方式是當電腦系統於一段時間沒有收到使用者的輸入時，即切斷H s y n c或/和V s y n c，使其無法傳送置螢幕端，而當螢幕端偵測不到Hsync或/和Vsync時，就自動關掉螢幕中某些元件的電能供應，使螢幕進入所謂「省電模J | Usually in computer systems, the computer host sends the video signal, horizontal sync signal (Hsync) and vertical sync signal (Vsync) to the screen through the screen display card. On screen. In order to save the power consumed by the screen in the computer system, the most common method today is to cut off the H sync or / and V sync when the computer system has not received user input for a period of time, making it impossible to send the screen When the screen cannot detect Hsync or / and Vsync, it will automatically turn off the power supply of some components in the screen, so that the screen enters the so-called "power saving mode"

五、發明說明（2) 式」；甚至也發展出「多階段的省電模式」，例如：根據預先設定的不同條件分別使螢幕進入第一或第二省電模式。而現今技術之螢幕省電模式控制方式，均需要明確地定義出進入第一及第二省電模式的控制方式；但一般顯示卡有時會隨著廠家設計選擇而有不同的省電信號中斷的排列組合方式。如：（1 ) Vysnc信號中斷進入第一省電模式，H s y n c信號中斷時進入第二省電模式；或（2 ) V y s n c信號中斷進入第一省電模式，V s y n c及H s y n c信號同時中斷時進入第二省電模式。因此，螢幕有時必須針對所搭配之顯示卡控制方式進行調整，才能達到正確的省電控制方式，否則螢幕就無法根據原先所設定的條件正確進入預設的各種省電模式。中進幕動螢自之下統件系條腦同電不種據。一依題另：可問供幕述提螢上於得決在使解的，以目置，明裝式發其模本及電，法省此方的因的確電正省入請參考圖一，圖一為本發明電腦系統1 〇之示意圖。本發明電腦系統1 0主要包含有一電腦主機1 2、一螢幕1 4以及至少一輸入裝置1 6，電腦主機1 2會傳送影像晝面信號1 7、水平同步信號1 8及垂直同步信號1 9至螢幕1 4，以控制螢幕 1 4上晝面之顯示，而輸入裝置1 6則可以是一鍵盤、滑鼠、5. Description of the invention (2) mode "; even" multi-stage power saving mode "has been developed, for example: the screen is put into the first or second power saving mode according to different preset conditions. The current screen-saving mode control methods of current technologies all need to clearly define the control mode for entering the first and second power-saving modes; however, the general display card sometimes has different power-saving signal interruptions depending on the design choice of the manufacturer. Permutations and combinations. For example: (1) the Vysnc signal is interrupted to enter the first power saving mode, and the H sync signal is interrupted to enter the second power saving mode; or (2) the V ysnc signal is interrupted to enter the first power saving mode, and the V sync and H sync signals are interrupted simultaneously When entering the second power saving mode. Therefore, the screen sometimes needs to be adjusted for the control method of the graphics card to be matched to achieve the correct power-saving control mode; otherwise, the screen cannot correctly enter the preset power-saving modes according to the originally set conditions. Middle-in-the-middle movements are from the bottom. One question by another: You can ask the confession to provide a solution to the solution. You can send the model and the electricity in the form of an eye-catching installation. The province ’s electricity is indeed being saved. Please refer to Figure 1.

This synchronizes the signal without interruption to the interruption module. The interruption module 24 can send the interruption number from the host 1 2 or the vertical signal 19. It cannot be a computer system. 1 〇 function block diagram. 20, a first timer 22, and a middle control the operation of the host computer 12, including data or programs, and a program in the processor 2 8 26. The first timer 22 is an inactive state when the state time exceeds a preset controller 20. The interrupt module 24 is a software and hardware device executed in the processor 28 according to the horizontal synchronization signal 18 or the vertical synchronization signal. When the controller 20 receives the signal, the interrupt module 24 will be activated. Sync signal 19 to send the horizontal sync signal to the screen 1 4. The screen 14 includes a second timer 36 (can be a love neck screen circuit 32, a detection device 34, a display (On Screen Dis ^ 's oscillator meter time element)) and-the screen screen will be based on Computer main unit 12 (SD) unit 38. Screen display circuit 32 Synchronization signal and various control signals for vertical synchronization, including: horizontal 17 conversion into image day and time $ $ = 1 will red, green and blue three-color image day and time Signal, /, on the display screen of the firefly 14. The detection device 3 4 470874 V. Description of the invention (4) It is electrically connected to the screen display circuit 3 2 and the second timer 36 6 for detecting the host computer 1 2 Whether to transmit the horizontal synchronization signal 18 and the vertical synchronization signal 19. The second timer 36 is also electrically connected to the screen display circuit 3 2 and the measuring device 34 and is used to perform the time counting function; when the second timer 3 6 When receiving the signal output from ^ Measure device 34, the second timer 36 will start timing, and send a signal to the screen display circuit after a preset period of time is reached. 0SD unit 38 can display a 0SD picture On screen 14 for the user to engage in setting a second plan If the display card is in the first power saving mode, only the horizontal synchronization signal is interrupted, and the vertical synchronization signal is still sent to the display; then the screen 14 can also use a counter to calculate the number received by the display. The number of pulses of the vertical synchronization signal to achieve the function of the second timer 36. If the frequency discriminating device (not shown) in the screen 14 determines that the current vertical synchronization signal Vsync frequency is 75Hz, the counter counts the pulse number to 7 5 When X 6 0 X 5 = 2 2 5 0 0, it means that the preset time period of 5 minutes has been reached. With the current IB compatible PCs currently available on the market, users can use the Microsoft Windows operating system console (c. n1: r〇l panel) Display option under the I directory to set the length of time scheduled by the first timer 22 2; so when the time scheduled by the first timer 22 2 arrives' first timing The device 22 can send a first power saving signal to start the subsequent actions of the related device. For example, if the "first power saving mode standby time" is set to ten minutes, when the user has not used for ten minutes When using a computer, the time counted by the rr device 22 on the first 50th day will reach ten minutes; so the first timer 22 will generate an interrupt signal to the interrupt module 24 to start the interrupt module 7 470874. (5) Interrupt the horizontal synchronization signal 18 or the vertical synchronization signal 19 so that it cannot be output to the screen 14. Please refer to FIG. 3, which is a schematic diagram of the 0SD screen 40 displayed by the 0SD unit 38 of the present invention. The 0SD day surface 40 on the screen 14 allows the user to set the length of time scheduled by the second timer 36, so that when the second timer 36 arrives, a power-saving signal can be sent to Initiate subsequent actions of related devices. For example, the stop 44 "second power saving mode standby time" on the OSD day 40 can be set to five minutes. When the horizontal synchronization signal 18 or vertical synchronization signal 19 is interrupted for five minutes, the second When counting, the time calculated by the device 36 will reach five minutes. In this way, a second power saving signal will be generated to the screen display circuit 32, so that the screen display circuit 32 will enter the second power saving mode. The OSD setting day surface 40 has an option “End” 46. After setting, the user can press this option to exit the OSD screen 40. It needs to be explained here that although the computer system 10 of the present invention is described by taking the OSD picture setting a single power saving mode as an example, it is not limited to this. Therefore, the stop 4 4 of the OSD setting picture i 4 0 is also It can be adjusted accordingly with the increase or decrease of the screen 14 power saving modes. Under normal conditions, the host computer 12 accepts the input commands from the input device 16 and transmits the red, green, and blue image daytime signal 17, horizontal synchronization signal 18, and vertical synchronization signal 19 to the screen 14. The screen display circuit 32 can display a corresponding image and display it on the display screen of the screen 14 in the daytime. As long as the input device 16 continues to accept new input commands from the user, it will reset

Timing. If the user does not input for ten minutes, the first timer 22 will count to ten minutes. This will generate an interrupt signal to the controller 20. After receiving the interrupt signal, the controller 20 will start the interrupt module. 2 4 to interrupt the horizontal sync signal 1 8 or vertical sync signal 丨 9 or both, making it impossible to send to the screen 14 ° Detector device in screen 1 4 3 4 is to continuously detect the horizontal sync signal 18 and vertical sync The presence of signal 19, when the detection device 34 does not detect the ^ horizontal synchronization signal and the vertical synchronization signal at the same time, the detection device 34 will send a first power-saving signal to the screen display circuit 32 to make the screen display The circuit 32 suspends the normal daytime display, and the screen 14 enters the first power saving mode. At the same time, the 'detection device 34 will also transmit the first power-saving signal to the second timer 36' to start the second timer 36. When the screen 14 enters the first power saving mode, the detection device 34 will continue to detect the presence of the horizontal synchronization signal 18 and the vertical synchronization signal 19. When will the detection device 34 detect the horizontal synchronization When the signal 1 8 and the vertical synchronization signal 19 exist at the same time, it means that the host computer 2 input device 丨 6 has received a new input command again, at this time, the detection device 3 4 will send a reply signal to the screen display circuit 3 2 makes it continue to display the normal day and day, so the curtain 14 leaves the first power saving mode and returns to its normal display state.
