本創作係有關於一種智慧型延伸顯示器識別資料模擬器,尤其是利用主控制單元自動讀取顯示器的延伸顯示能力識別資料,並儲存於記憶單元中,因而整體系統的系統主晶片可在不理會是否有顯示器被變更成另一型式之顯示器的情形,而直接利用記憶單元的延伸顯示能力識別資料,傳送所需畫面以驅動所有顯示器,所以使用者不需手動設定相關的必要參數,大幅簡化操作手續,避免人為錯誤,並同時解決相容性的問題。This author is about a smart extended display identification data simulator, especially using the main control unit to automatically read the extended display capability identification data of the display and store it in the memory unit, so that the system main chip of the overall system can be ignored. Whether there is a case where the display is changed to another type of display, and the extended display capability of the memory unit is used to directly identify the data, and the desired picture is transmitted to drive all the displays, so the user does not need to manually set the relevant necessary parameters, thereby greatly simplifying the operation. Procedures to avoid human error and solve compatibility problems at the same time.
一般,電腦系統是利用顯示器實現影像顯示功能,不過每家製造廠商所生產的顯示器可能會具有不同的顯示特點,比如解析度或螢幕大小,因此,顯示器是利用延伸顯示能力識別(Extended display identification data,簡稱EDID)以供系統讀取並設定,比如包含顯示器的基本顯示參數,比如製造商ID、生產ID碼、製造週、製造年份、基本顯示參數、色度調節、建立時脈I、建立時脈II、製造商保留的時脈、詳細時脈描述1~4、額外旗標、校驗和(Check Sum) ,或者,還可進一步包含影像輸入定義、最大水平圖形尺寸、最大垂直圖形尺寸、顯示伽瑪、電源管理和支援的特徵。Generally, the computer system uses the display to realize the image display function, but the display produced by each manufacturer may have different display characteristics, such as resolution or screen size. Therefore, the display is extended display identification data. , referred to as EDID) for system reading and setting, such as including the basic display parameters of the display, such as manufacturer ID, production ID code, manufacturing week, manufacturing year, basic display parameters, chroma adjustment, clock generation, setup time Pulse II, manufacturer-reserved clock, detailed clock description 1~4, extra flag, checksum, or, further, image input definition, maximum horizontal graphic size, maximum vertical graphic size, Displays gamma, power management, and support features.
通常,EDID是存在於顯示器的PROM或EEPROM內,而電腦系統如要讀取EDID的資料,可透過I2C,其中slave address的預設值為0x50。Usually, the EDID is stored in the PROM or EEPROM of the display, and the computer system can read the EDID data through I2C, and the default value of the slave address is 0x50.
不過,使用者常遇到以下問題。However, users often encounter the following problems.
問題一,當更換螢幕後,如果在Windows作業系統(Window XP、Win7或Win8)下的顯示畫面會變小而無法佔滿整個螢幕,則需要正確調整顯示參數。通常是設定變更解析度,並將縮放比例變更為「全螢幕」,以使得畫面大小能占滿螢幕的整個可視範圍。不過對於不太熟悉電腦設定的廣大使用者而言,實際的設定操作是相當複雜且不便。舉例而言,使用nVidia顯示卡、AMD_ATI顯示卡或Intel內建顯示功能時,需要不同的相對應設定方式。Problem 1: When the screen is replaced, if the display screen under the Windows operating system (Window XP, Win7 or Win8) becomes smaller and cannot fill the entire screen, the display parameters need to be adjusted correctly. It is usually set to change the resolution and change the zoom ratio to "full screen" so that the screen size can fill the entire viewing range of the screen. However, for a large number of users who are not familiar with computer settings, the actual setting operation is quite complicated and inconvenient. For example, when using an nVidia display card, an AMD_ATI display card, or Intel built-in display function, different corresponding setting methods are required.
問題二,在多螢幕使用時,如果驅動程式已重新安裝,數位看板軟體辨識是沒問題也已經設定完成。但如果螢幕出現問題必須更換時,數位看板軟體也必須重新設定去排列新的螢幕順序,對於一般使用者並不方便。Question 2: When the multi-screen is used, if the driver has been reinstalled, the digital kanban software identification is no problem and has been set. However, if there is a problem with the screen that must be replaced, the digital kanban software must also be re-arranged to arrange the new screen sequence, which is not convenient for the average user.
問題三,螢幕串接後發生辨識錯誤,換言之,如果要將電腦連接電腦切換器(KVM)或影音訊號的延伸器時,當『電腦』與『螢幕』間串接這些訊號切換、分配或延伸器材後,電腦端會認不得顯示器的解析度。例如,24吋顯示器的最佳模式為1920x1080,而經過訊號串接後,電腦的顯示設定中卻突然找不到這個解析度,或者螢幕顯示無法確實填滿畫面、色彩不正確等問題,且無論如何調整都不行。會發生此狀況,是因為電腦偵測顯示器的EDID資料,無法正確辨識所致,當使用者串接KVM、HDMI、DVI分配器、DVI切換器或Cat.5延伸器,會容易發生無法正確辨識EDID資訊的情形。Question 3: A recognition error occurs after the screen is connected. In other words, if you want to connect the computer to the KVM or the extender of the audio and video signals, when the "computer" and the "screen" are connected in series, these signals are switched, assigned or extended. After the equipment, the computer will recognize the resolution of the display. For example, the best mode for a 24-inch display is 1920x1080. After the signal is connected in series, the resolution of the computer suddenly cannot be found in the display setting, or the screen display cannot fill the screen, the color is incorrect, etc. How to adjust will not work. This happens because the computer detects the display's EDID data and cannot be correctly identified. When the user connects KVM, HDMI, DVI splitter, DVI switch or Cat.5 extender in series, it will easily occur and cannot be correctly identified. The situation of EDID information.
因此,很需要一種創新的智慧型延伸顯示器識別資料模擬器,係利用主控制單元自動讀取顯示器的延伸顯示能力識別資料,並儲存於記憶單元中,因而整體系統(比如電腦系統)的系統主晶片可在不理會是否有顯示器被更和成另一型式之顯示器的情形,而直接利用記憶單元的延伸顯示能力識別資料,傳送所需畫面以驅動所有顯示器,所以使用者不需手動設定相關的必要參數,大幅簡化操作手續,避免人為錯誤,藉以解決相容性的問題,同時解決上述習用技術的問題。Therefore, there is a great need for an innovative smart extended display identification data simulator that uses the main control unit to automatically read the extended display capability identification data of the display and store it in the memory unit, thus the system master of the overall system (such as a computer system). The chip can directly use the extended display capability of the memory unit to identify the data regardless of whether the display is replaced with another type of display, and transmit the desired picture to drive all the displays, so the user does not need to manually set the relevant The necessary parameters greatly simplify the operation procedures and avoid human error, so as to solve the problem of compatibility and solve the problems of the above-mentioned conventional technologies.

The transmission unit is connected to the display card, and under the control of the main control unit, the extended display identification data and the display connection configuration data are transmitted to the display card according to the display data request from the display card.
進一步,系統主晶片是在執行作業系統(比如微軟的Windows)後,並在啟動智慧型延伸顯示器識別資料模擬器讀取功能時,可驅動顯示卡而對智慧型延伸顯示器識別資料模擬器提出顯示器資料請求,藉以接收來自顯示卡的延伸顯示器識別資料以及顯示器連結組態資料,並據以動態更新該至少一顯示器所對應的驅動程式。此外,可經由顯示卡及智慧型延伸顯示器識別資料模擬器,傳送相對應的至少一顯示畫面至該至少一顯示器而個別顯示。Further, the system main chip is after executing the operating system (such as Microsoft Windows), and when the smart extended display identification data simulator reading function is activated, the display card can be driven to present the display to the smart extended display identification data simulator.

In addition, the data emulator may be identified by the display card and the smart extended display, and the corresponding at least one display screen is transmitted to the at least one display for individual display.
顯而易見的,由於本創作的智慧型延伸顯示器識別資料模擬器利用主控制單元自動讀取顯示器的延伸顯示能力識別資料,並儲存於記憶單元中,因而整體系統(比如電腦系統)的系統主晶片可在不理會是否有顯示器被更和成另一型式之顯示器的情形,而直接利用記憶單元的延伸顯示能力識別資料,傳送所需畫面以驅動所有顯示器,所以使用者不需手動設定相關的必要參數,大幅簡化操作手續,避免人為錯誤,確實解決相容性的問題。Obviously, since the intelligent extended display identification data simulator of the present invention uses the main control unit to automatically read the extended display capability identification data of the display and store it in the memory unit, the system main chip of the overall system (such as a computer system) can be In the case of ignoring whether or not the display is further integrated into another type of display, the information of the extended display capability of the memory unit is directly used to transmit the desired picture to drive all the displays, so the user does not need to manually set the relevant necessary parameters. , greatly simplify the operation procedures, avoid human error, and indeed solve the compatibility problem.
以下配合圖示及元件符號對本創作之實施方式做更詳細的說明,俾使熟習該項技藝者在研讀本說明書後能據以實施。The implementation of the present invention will be described in more detail below with reference to the drawings and component symbols, so that those skilled in the art can implement the present specification after studying the present specification.
請參閱第一圖,顯示本創作第實施例智慧型延伸顯示器識別資料模擬器的示意圖。如第一圖所示,本創作實施例的智慧型延伸顯示器識別資料模擬器10連接至少一顯示器20以及顯示卡30,且包括讀取單元12、主控制單元14、記憶單元16以及傳輸單元18,其中讀取單元12、記憶單元16以及傳輸單元18是連接至主控制單元14,並由主控制單元14控制讀取單元12、記憶單元16以及傳輸單元18的電氣操作功能。此外,讀取單元12是連接每個顯示器20,而傳輸單元10是連接位於主機板(圖中未顯示)上的顯示卡30,且顯示卡30進一步連接至位於同一主機板上的系統主晶片40(亦即中央處理器,CPU)。Referring to the first figure, a schematic diagram of the intelligent extended display identification data simulator of the first embodiment of the present invention is shown. As shown in the first figure, the smart extended display identification data simulator 10 of the present embodiment is connected to at least one display 20 and the display card 30, and includes a reading unit 12, a main control unit 14, a memory unit 16, and a transmission unit 18. The reading unit 12, the memory unit 16, and the transmission unit 18 are connected to the main control unit 14, and the main control unit 14 controls the electrical operation functions of the reading unit 12, the memory unit 16, and the transmission unit 18. In addition, the reading unit 12 is connected to each display 20, and the transmission unit 10 is connected to the display card 30 located on the motherboard (not shown), and the display card 30 is further connected to the system main chip located on the same motherboard. 40 (also known as CPU, CPU).
具體而言,每個顯示器20具有個別的延伸顯示能力識別資料(Extended display identification data,EDID),且顯示卡30是藉影像傳輸介面而連接至每個顯示器20,其中影像傳輸介面可包含一般的VGA、D-S-sub或HDMI。Specifically, each display 20 has an individual extended display identification data (EDID), and the display card 30 is connected to each display 20 through an image transmission interface, wherein the image transmission interface can include general VGA, DS-sub or HDMI.
主控制單元14可自動偵測顯示器20是否連接至讀取單元12,並進而讀取每個顯示器20的延伸顯示能力識別資料(EDID),同時,依據每個顯示器20連接至讀取單元12的連結組態,建立相對應的顯示器連結組態資料。此外,主控制單元14將延伸顯示器識別資料及顯示器連結組態資料傳送至記憶單元16而儲存,以供主控制單元14後續需要時讀取之用。The main control unit 14 can automatically detect whether the display 20 is connected to the reading unit 12, and then read the extended display capability identification data (EDID) of each display 20, while being connected to the reading unit 12 according to each display 20. Link the configuration and establish the corresponding display link configuration data. In addition, the main control unit 14 transfers the extended display identification data and the display connection configuration data to the memory unit 16 for storage for later reading by the main control unit 14.
再者,傳輸單元18連接至顯示卡30,用以在主控制單元14的控制下,依據來自顯示卡30的顯示器資料請求,將延伸顯示器識別資料以及顯示器連結組態資料回傳至顯示卡30。Furthermore, the transmission unit 18 is connected to the display card 30 for transmitting the extended display identification data and the display connection configuration data to the display card 30 according to the display data request from the display card 30 under the control of the main control unit 14. .
進一步而言,系統主晶片40是在執行特定的作業系統(Operation System)下,比如Windows或Linux,並在啟動預設的智慧型延伸顯示器識別資料模擬器讀取功能後,藉以驅動顯示卡30而對本創作的智慧型延伸顯示器識別資料模擬器10提出上述的顯示器資料請求,進而接收來自顯示卡30的延伸顯示器識別資料以及顯示器連結組態資料,並據以動態更新每個顯示器20所對應的驅動程式(Driver),同時,經由顯示卡30及智慧型延伸顯示器識別資料模擬器10而傳送相對應的至少一顯示畫面至上述的至少一顯示器20而個別顯示。Further, the system main chip 40 is executed under a specific operation system (such as Windows or Linux), and after driving the preset smart extension display identification data simulator reading function, the display card 30 is driven. The intelligent extended display identification data simulator 10 of the present invention proposes the above-mentioned display data request, and further receives the extended display identification data from the display card 30 and the display connection configuration data, and dynamically updates each display 20 accordingly. The driver (Motor) simultaneously transmits the corresponding at least one display screen to the at least one display 20 via the display card 30 and the smart extended display identification data simulator 10 for individual display.
此外,主控制單元14可利用微控制器(MCU)或微處理器而實現,或者,讀取單元12、主控制單元14及傳輸單元18可整合成高功能性的單一晶片。In addition, the main control unit 14 can be implemented by a microcontroller (MCU) or a microprocessor, or the reading unit 12, the main control unit 14 and the transmission unit 18 can be integrated into a single chip of high functionality.
要注意的是,系統主晶片40也可啟動顯示卡30,而經由影像傳輸介面以直接讀取每個顯示器20的延伸顯示能力識別資料,進而完成對每個顯示器20的規畫(Configuration),以正確顯示所傳送的畫面。It is to be noted that the system main chip 40 can also activate the display card 30, and directly read the extended display capability identification data of each display 20 via the image transmission interface, thereby completing the configuration of each display 20. The displayed picture is displayed correctly.
更加具體而言,主控制晶片14提供二種操作模式,包含自動學習模式以及手動模式,用以供系統主晶片40在作業系統下選取。More specifically, the master control wafer 14 provides two modes of operation, including an automatic learning mode and a manual mode, for the system master wafer 40 to be selected under the operating system.
進一步,自動學習模式可偵測目前所使用的所有顯示器的類別(如CRT, DVI, HDMI等),並將相關資料(亦即EDID)下載後儲存,等待顯示卡30執行呼叫處理。當主控制晶片14處於自動學習模式時,可選擇記憶首次使用的顯示器20或是最後使用的顯示器20,並且在將相關資料設定完畢後,等待顯示卡30讀取。Further, the automatic learning mode can detect the types of all the displays currently used (such as CRT, DVI, HDMI, etc.), and download and store the related data (ie, EDID), waiting for the display card 30 to perform call processing. When the main control chip 14 is in the automatic learning mode, it is possible to select to store the first used display 20 or the last used display 20, and wait for the display card 30 to read after setting the relevant data.
另外,手動模式則可使用通訊介面(如 RS232等)直接將顯示器20的解析度及型號之資料予以設定,可有效避免因顯示器20的相容性問題(比如設備信號不良)或環境因素(設備供電順序不同),而導致的軟體問題。再者,當處於手動模式時, 可由軟體提供相關的資訊(比如解析度及型號等),並由通訊介面通知主控制晶片14,且在資料設定完畢後,觸發顯示卡30要求重新偵測所有的顯示器20。In addition, the manual mode can use the communication interface (such as RS232) to directly set the resolution and model data of the display 20, which can effectively avoid the compatibility problem of the display 20 (such as poor device signal) or environmental factors (device The power supply sequence is different), resulting in software problems. Moreover, when in the manual mode, relevant information (such as resolution and model number) can be provided by the software, and the main control chip 14 is notified by the communication interface, and after the data setting is completed, the display card 30 is triggered to request to re-detect all. Display 20.
在實際應用上,如果是只配置單一顯示器20,因智慧型延伸顯示器識別資料模擬器10會自動讀取並儲存顯示器20的延伸顯示能力識別資料,所以系統主晶片40可不需讀取顯示器20的延伸顯示能力識別資料,而是直接利用智慧型延伸顯示器識別資料模擬器10所儲存的資料,因此,整體操作簡單。尤其是,當使用者更換顯示器20且如果更新的顯示器20具有不同的延伸顯示能力識別資料時,系統主晶片40只要依據來自智慧型延伸顯示器識別資料模擬器10的資料而更新驅動器及畫面顯示的解析度,即可將所需的畫面正確顯示於更新的顯示器20,不會有相容性的問題,使用者更不必啟動作業系統下的顯示器設定功能而費心設定各個必要參數,能達到隨插即用的目的。In practical applications, if only the single display 20 is configured, since the smart extended display identification data simulator 10 automatically reads and stores the extended display capability identification data of the display 20, the system main chip 40 does not need to read the display 20 By extending the display capability identification data, the information stored in the data simulator 10 is directly recognized by the smart extension display, and thus the overall operation is simple. In particular, when the user replaces the display 20 and if the updated display 20 has different extended display capability identification data, the system main chip 40 only needs to update the driver and the screen display according to the data from the smart extended display identification data simulator 10. With the resolution, the desired picture can be correctly displayed on the updated display 20. There is no compatibility problem, and the user does not need to start the display setting function under the operating system and troublesomely sets various necessary parameters to achieve the insertion. The purpose of use.
對於使用多個顯示器20的應用場合,比如類似電視牆的大型數位顯示設備,則不論使用者更換顯示器20的數目,本創作的模擬器會即時將更新後的所以顯示器20的資料自動儲存,使得系統主晶片40不需理會顯示器20是否已更換,只要依據智慧型延伸顯示器識別資料模擬器10目前所儲存的資料而正確使用所需的驅動程式,進而將畫面顯示於所有的顯示器20上。例如,當系統主晶片40將所需畫面連續顯示於顯示於矩陣排列的多個顯示器20上時,亦即造成跑馬燈效應,即使其中的某一顯示器20因損壞或故障而被更換成另一製造廠的不同型式之顯示器20時,系統主晶片40仍能驅動所有顯示器20而顯示畫面,不需重新設定必要參數。For applications using multiple displays 20, such as large digital display devices like video walls, the simulator of the present application will automatically store the updated information of the display 20, regardless of the number of displays 20 replaced by the user. The system main chip 40 does not need to pay attention to whether the display 20 has been replaced, and the screen is displayed on all the displays 20 by correctly using the required driver according to the data currently stored by the smart extension display identification data simulator 10. For example, when the system main chip 40 continuously displays the desired picture on the plurality of displays 20 displayed on the matrix arrangement, it also causes a marquee effect even if one of the displays 20 is replaced with another one due to damage or malfunction. When the manufacturer's different types of displays 20 are in place, the system master wafer 40 can still drive all of the displays 20 to display the screen without having to reset the necessary parameters.
綜上所述,本創作的主要特點在於利用主控制單元自動讀取顯示器的延伸顯示能力識別資料,並儲存於記憶單元中,因而整體系統(比如電腦系統)的系統主晶片可在不理會是否有顯示器被更和成另一型式之顯示器的情形,而直接利用記憶單元的延伸顯示能力識別資料,傳送所需畫面以驅動所有顯示器,所以使用者不需手動設定相關的必要參數,大幅簡化操作手續,避免人為錯誤,並同時解決相容性的問題。In summary, the main feature of this creation is that the main control unit automatically reads the extended display capability identification data of the display and stores it in the memory unit, so that the system main chip of the overall system (such as a computer system) can be ignored. In the case where the display is further integrated into another type of display, the extended display capability of the memory unit is used to directly identify the data, and the desired picture is transmitted to drive all the displays, so that the user does not need to manually set relevant necessary parameters, thereby greatly simplifying the operation. Procedures to avoid human error and solve compatibility problems at the same time.
