顯示器是電腦必要的配備之_，其形式上從早年的陰 極射線管式螢幕到目前的液晶顯示器，在體積、重量，乃 至於尺寸上都出現極大的變革，且為配合電腦相關技術的 需求，顯示器必須作相應的支援，首先在顯示頻率方面， 早期顯示器的顯示比例為5:4,目前則有支援16:1〇的需 求，除此以外，必須支援更多的顯示頻率，儘管目前的顯 示器均内建自動調整功g ’但顯示器目前必須支援的顯示 頻率甚多且十分接近（例如：1〇24 χ 768、128〇 χ 7邸、 1360 X 768等），因此顯示器執行自動調整功能時十分容 易出現誤判（例如將1〇24 X 768誤判為128〇 X 768或 1360 X 768)，造成顯示畫面偏移或無法滿框等問題。 再者，由於電腦科技的快速發展而不斷擴展其與其巧 媒體的關連性，因此電腦顯示器除了傳統的vga(d_su1 輸入埠外，進一步加入數位訊號輸入埠（如DV卜D、η D|^ 等）及類比訊號輸入埠（如CVBS、Y/C、Ypbpr等），以< 為各種影像訊㉟的顯示終端。冑管顯Μ支援前述的心 4 1360807 、類比影像訊號顯示功能’但在切換訊號源的方式上仍未 盡便利：既有顯示器切換訊號源時，大致是利用顯示器内 建的OSD(On Screen Display)選單加以選擇，而選擇訊號 源是OSD選單其中一個選項，在叫出主選單後，利用顯 不器上的選項鍵移到指定的選項，並執行下一層的子選單 ，始能在該子選單上顯示訊號源以供切換，其操作上顯然 十分不便。 【發明内容】 由上述可知，既有顯示器的自動調整功能對於頻率相 近的輸人訊號十分容㈣斷錯誤，造成顯示畫面偏移或益 法滿框等狀況，故有待進—步檢討，並謀求可行的解決方 丨本啊，丨、命W八虱號頻The display is the necessary equipment for the computer. Its form has changed greatly from the early cathode ray tube screen to the current liquid crystal display, and it has changed greatly in size, weight and even size. In order to meet the needs of computer related technology, The display must be supported accordingly. First, in terms of display frequency, the display ratio of the early display is 5:4. Currently, there is a need to support 16:1〇. In addition, more display frequencies must be supported, even though the current display The built-in automatic adjustment function is 'but the display must support a very high display frequency and is very close (for example: 1〇24 768 768, 128〇χ 7邸, 1360 X 768, etc.), so the display performs the automatic adjustment function very much. It is prone to misjudgment (for example, misidentifying 1〇24 X 768 as 128〇X 768 or 1360 X 768), causing problems such as display offset or failure to fill the frame. Furthermore, due to the rapid development of computer technology, it has continuously expanded its connection with its smart media. Therefore, in addition to the traditional vga (d_su1 input port, computer monitors further add digital signal input ports (such as DV Bu D, η D|^, etc.) ) and analog signal input 埠 (such as CVBS, Y/C, Ypbpr, etc.), < is the display terminal of various video messages 35. Μ管显ΜSupport the aforementioned heart 4 1360807, analog image signal display function 'but switching The way of the signal source is still not convenient: when the display switches the signal source, it is roughly selected by using the built-in OSD (On Screen Display) menu, and the selection signal source is one of the OSD menus. After the menu is selected, the option button on the display device is used to move to the specified option, and the sub-menu of the next layer is executed, and the signal source can be displayed on the sub-menu for switching, which is obviously inconvenient in operation. It can be seen from the above that the automatic adjustment function of the display is very close to the input signal with similar frequency, and the display screen is offset or the frame is full.

The frequency of 2% =: The main technical means adopted is defined first - similar to the leather, which classifies the similar display frequencies and constructs them separately, and enters the phase after the display is turned on. The following steps are performed: Manjin A near frequency Judging the mode, and performing the judgment that the input signal frequency of the display is the defined display frequency; h(4) in the any-menu group 5, the foregoing step determining result is the menu group to which the input signal belongs; that is, generating a shortcut menu to display the waiting wheel Enter the operation menu; the user element displays the frequency selection; close the menu to complete the display frequency setting. Before the use, the signal is automatically generated when the signal that is turned into the display is a similar frequency. Since the shortcut display list shows the similar display frequency, the user can select the correct display frequency by himself. The screen is offset or cannot be full due to an error. The method just described determines that the input signal frequency of the display belongs to any selected display frequency, and the production menu is displayed when any of the following conditions occurs: the computer connected to the π and .4 displays is turned back on; the display itself is restarted; The video connection is re-plugged; the computer's display card switches the output frequency. The purpose of the month is to provide a fast switching method for the signal source, which is to change the g & speed key (HGt ΚβΥ) and the shortcut menu to facilitate the user to quickly cut: the input source of the factory and the device to solve the traditional display must pass Multi-layer menus can begin to complete the shortcomings of switching. The main technical means adopted for the purpose of the description is at the display; in the month, in the near-frequency discrimination mode, the following steps are performed: = whether there is a wheel-in action of the designated button on the display; Further judge whether all the shadows of the display 1360807 are input or not. If the image input of the display has signal input, all input ports are automatically detected, and a shortcut menu is generated to list all valid inputs for switching the selection signals. Source; ^ If the image input of the monitor is no signal input, then it is judged whether the computer signal input on the display is in the power saving mode. If not, all input ports are automatically detected, and a shortcut menu is generated to list all valid inputs.埠, for switching to select the source of the signal, and if so, all input ports are automatically detected and switched directly to another source. By using the foregoing method, the user can use the shortcut keys defined by the display in the near frequency discrimination mode to generate a menu and quickly switch the signal source, thereby solving the problem that the conventional display uses the multi-layer tree OSD menu to switch the signal source. The shortcomings. [Embodiment] In a preferred embodiment of the present invention, the input of a display is removed from the VGA (D-sub), and further has a digital signal input port (such as dv, d, HDM, etc.) and an analog signal input port ( Such as CVBS, Y/c, Ypbpr, etc., when the display is connected with the computer's display card with VGA input, and the VGA input has signal input, the control circuit in the display starts a near-frequency discrimination mode' The similar frequency discrimination mode is executed, and the control circuit groups the built-in frequency group, the so-called similar frequency group classifies the similar display frequencies, and groups a plurality of similar display frequencies into a menu group, for example: 7 1360807 Menu Group A: 640 X 480, 848 X 480 Menu Group B: 1024 X 768, 1280 X 768, 1360 X 768 Menu Group C: 1400 X 1050, 1680 X 1050 Menu Group D: 640 X 400 720 X 400, 640 X 480@70 Menu group E: 640 X 350, 720 X 350 (The above grouping is for convenience of explanation and understanding, the group content is not limited to the above list) About the specific frequency discrimination mode Process, please refer to the following (Refer to the first figure): According to the VGA input, whether there is signal input, decide whether to start the "near frequency discrimination mode" (101); if the VGA input has no signal, it will perform the automatic adjustment function (102). ), · Conversely, if V (3A input 讯 has signal input ', the "similar frequency discrimination mode" is activated, and then it is judged whether the frequency of the signal sent by the vga input belongs to the explicit frequency defined in any menu group (1) 〇3), if it is not the display frequency defined in the similar frequency group, the automatic adjustment function is performed; otherwise, if it is the display frequency of the similar frequency group, then the step shown in the first figure (kidney) When any of the conditions (1〇7) is established, a shortcut menu is generated in the form of the 0SD menu. (Outline: the menu group to which the display frequency is not displayed. For example, the signal frequency input by the VGA input is X 768. , which belongs to the above listed menu, the resulting shortcut menu will display the display frequency options such as "1〇24 χ 768' coffee 768, 1360 X 768" (if the system will enter one of the waiting for typing actions (1〇9)) 'Connect 15 - „ . „Step' is used by the user to use the option button that is not stolen, according to the display of the computer~ 卞 疋 疋 选 选 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 Menu (111) and update the setting (112), and return to step (1〇3). As mentioned before, when the VGA input 埠 input signal frequency is similar, and meet the steps in the first figure ( In any of the conditions of 1〇4 (1〇7), a shortcut menu will be generated for the user to select the correct display frequency. The above conditions are further detailed as follows: The computer connected to the display is turned back on (彳〇4); The display itself Reboot (1〇5); VGA input of the monitor is re-plugged (1〇6); the display card of the computer switches the output frequency (1〇7). In the foregoing "near frequency discrimination mode", the present invention further provides a signal source fast switching mode, as shown in the third figure, to determine whether there is a button action on the display (3〇彳), and if so, then judge 疋No is the keystroke action (3〇2) of the specified button. The so-called designated button can be the existing button on the display, such as the menu button, which is redefined as a dedicated heat source for switching the signal source in the "near frequency discrimination mode". In addition, the designated button may also be a new dedicated key used for switching the signal source 'or a composite key combining the original keys; if the result of the step (302) is YES, the display is further determined one by one. Whether all the image input 有 has signal input, as shown in the third step (303 (306), the so-called image input 埠 can include: hdmi, CVBS, Y/C, YpbPr, etc., if any image input When there is a signal input, it will automatically detect all inputs (3〇7) and generate a shortcut menu (308) to list all valid inputs (as shown in the fourth figure). User 9 1360807 selects the source of the signal to be switched, then waits for the typing action (3〇9), and after the selection is completed, proceeds to step (310) to execute the switching signal source' and then closes the menu (311), and then completes the new setting (312). ), and then returning to the step (3〇2 in the present embodiment, the above-mentioned shortcut menu except the signal source that has been confirmed to be valid after detection) also includes an automatic adjustment function; and the step (303 (306) is sequentially determined. When there is no signal input for all kinds of image input ', then it is judged whether the VGA or DVI-D input on the display is in the power saving mode (31 3). If not, all input 埠 (3〇7) is automatically detected. A shortcut menu is generated to list all valid input ports (3〇8) for switching the selection signal source; if so, then directly switch to another signal source (314), and after resetting (312), return to step (302). The hotkey switching signal source function provided by the foregoing process makes the user more convenient and convenient when switching to the signal source requirement. In the foregoing method, the VGA input is involved, whether the input signal is a similar frequency and various digital or analog inputs are There is a signal input judgment, and the specific technical means for performing the above-mentioned judgment operation is as follows: Please refer to the fifth figure. When the display control circuit uses the VGA input as the judgment object, the main input is VGA input. (D-sub) (50) pins 13, 14 (VGA-HS, VGA-VS) are used as the judgment object, according to the signal (NO signal), signal (signal), beyond the readable range signal (out Signal range status such as of range signal and near timing signal. Since the HDMI input is backward compatible with DV D, the HDMI connector (60) shown in Figure 6 is used as the aforementioned HDMI and DVhD input. , by 10 1360807 its pin 19 "RX HOTPLUG" status is 'Η', then judge DVhD or HDMI input 埠 as a valid signal source, such as "rx HOTPLUG" status is 'L', then judge DVI-D or HDM丨Input no signal; according to the Infoframe format contents of four groups of TMDS signals such as CLK+, CLK-, DATA0+, DATA0-, DATA1 +, DATA1-, DATA2+, DATA2- on the HDM丨 connector (60), DV can be judged. D (PC signal) or HDMI (video signal) input Source and format to distinguish between NO signal, signal, and ut of range signal ° As for CVBS, Y/C, YpbPr, etc., they are analog video sources. 'The CVBS system combines Hsync 'Vsync in the signal'. Both Hsync and Vsync of Y/C and YpbPr are in the Y signal. An analog digital converter (ADC) can be used to distinguish between no signal, signal, and out of range signals.
