Description
技术领域 technical field
本发明有关于一种显示控制方法，且特别是有关于一种用以动态控制显示装置的设置的显示控制方法与显示装置。The present invention relates to a display control method, and in particular to a display control method and a display device for dynamically controlling settings of a display device.
背景技术 Background technique
近年来显示器日益进步并逐渐多样化，为方便使用者设定显示装置，当显示信号源和显示装置连接时，两者会通过显示传输界面来读取特定的显示设置标签，例如延伸显示能力识别数据(Extendeddisplayidentificationdata,EDID)。通过延伸显示能力识别数据的内容来得知显示装置的设定、显示条件与限制等等。In recent years, displays have become increasingly advanced and diversified. For the convenience of users to set display devices, when the display signal source and display device are connected, the two will read specific display setting tags through the display transmission interface, such as extended display capability identification Data (Extended display identification data, EDID). By extending the content of the display capability identification data, the settings of the display device, display conditions and restrictions, etc. are known.
传统的EDID设置方法，是由外部的延伸显示能力识别数据写入器(EDIDwriter)或微控制器(MicrocontrollerUnit,MCU)，在显示装置出厂时将EDID预先写入非易失性存储单元，例如，电子抹除式可复写只读存储器(Electrically-ErasableProgrammableRead-OnlyMemory,EEPROM)。现有作法中，当显示装置出厂后其保存的EDID即无法随意变更。The traditional EDID setting method is to use an external extended display capability identification data writer (EDIDwriter) or a microcontroller (MicrocontrollerUnit, MCU) to pre-write the EDID into a non-volatile storage unit when the display device leaves the factory, for example, Electrically Erasable Programmable Read-Only Memory (EEPROM). In the existing practice, the EDID stored in the display device cannot be changed arbitrarily after it leaves the factory.
在EDID中详述目前显示装置的状态及信息，以利供显示信号源可得知目前驱动的显示装置所须的信号规格，以发送适当的信号格式给显示装置来显示。此外，显示信号源更会根据显示装置上的EDID内容进而开启或关闭特殊的显示驱动功能。The status and information of the current display device are described in detail in the EDID, so that the display signal source can know the signal specification required by the currently driven display device, and send an appropriate signal format to the display device for display. In addition, the display signal source will turn on or off a special display driver function according to the EDID content on the display device.
当显示装置上的显示设置标签(如EDID)属于特定的格式或协议时，显示信号源读取后将开启或关闭某些特定的显示驱动功能，例如，支援显示装置实作边缘融合(EdgeBlending)功能所需的水平/垂直延伸(horizontal/verticalexpand)功能。然而，现有显示装置的显示设置标签为出厂时预先设置的无法动态变更，使得某些应用下导致显示装置与显示信号源的部份显示驱动功能被强制关闭。也就是说，显示装置上无法更动的显示设置标签将限制其应用上的弹性。When the display setting tag (such as EDID) on the display device belongs to a specific format or protocol, the display signal source will turn on or off certain specific display driver functions after reading, for example, support the display device to implement edge blending (EdgeBlending) The horizontal/verticalexpand function required by the function. However, the display setting label of the existing display device is preset at the factory and cannot be dynamically changed, so that some display driver functions of the display device and the display signal source are forcibly turned off in some applications. That is to say, the unchangeable display setting label on the display device will limit the flexibility of its application.

具体实施方式 detailed description
于本发明揭示一种显示控制方法，用以控制显示装置动态调整其本身的显示设置标签。于一实施例中，显示装置可为投影机，或也可为其它显示器。于此实施例中，显示装置上的显示设置标签可为显示能力识别数据(Extendeddisplayidentificationdata,EDID)。The present invention discloses a display control method for controlling a display device to dynamically adjust its own display setting label. In one embodiment, the display device may be a projector, or may also be other displays. In this embodiment, the display setting tag on the display device may be display capability identification data (Extended display identification data, EDID).
显示能力识别数据是基于使用者即插即用(PlugandPlay)的需求下由视频电子标准协会(VideoElectronicsStandardsAssociation,VESA)所制定的标准协议，在数字视频界面(DigitalVisualInterface,DVI)协议与高解析多媒体界面(High-DefinitionMultimediaInterface,HDMI)协议的下的显示装置中皆保存有显示能力识别数据。The display capability identification data is a standard protocol formulated by the Video Electronics Standards Association (VESA) based on the user's Plug and Play (Plug and Play) requirements. The Digital Visual Interface (DVI) protocol and the high-resolution multimedia interface ( The display devices under the High-DefinitionMultimediaInterface (HDMI) protocol all store display capability identification data.
目前的显示应用场合中对大显示画面的需求渐渐提高，信号源端也具备同时输出多个显示画面的能力。于是厂商开发出以多台显示装置合并为单一大荧幕的技术。请参阅图1，其绘示多台显示装置以边缘融合(EdgeBlending)功能合并显示的示意图。如图1所示，边缘融合功能是以显示信号源100驱动多台投影机102，在投影屏幕104上形成较大尺寸的投影画面106，其中多台投影机102投出的子画面(106a与106b)的边缘相互接合以形成更大尺寸的投影画面106，其中图1所绘示的是具有边缘融合(EdgeBlending)功能的投影机搭配具有水平/垂直延伸功能的显示信号源。In current display applications, the demand for large display images is gradually increasing, and the signal source also has the ability to output multiple display images at the same time. Therefore, manufacturers have developed a technology that combines multiple display devices into a single large screen. Please refer to FIG. 1 , which shows a schematic diagram of combining display of multiple display devices with an edge blending (EdgeBlending) function. As shown in FIG. 1 , the edge blending function is to drive multiple projectors 102 from a display signal source 100 to form a larger-sized projection screen 106 on a projection screen 104, wherein the sub-pictures (106a and 106a) projected by multiple projectors 102 The edges of 106b) are joined together to form a larger-sized projection screen 106 , wherein FIG. 1 shows a projector with edge blending (EdgeBlending) function paired with a display signal source with horizontal/vertical extension function.
而在利用多台投影机利用边缘融合功能来投射出更大的画面时，显示信号源100(如显示卡)必须拥有可以在不同显示器，同时显示出同一个画面，并且将其画面作水平或垂直切割及延伸并同时供给左右或上下画面来显示的能力，此时，显示信号源100须启动水平/垂直延伸驱动功能。When utilizing the edge blending function of multiple projectors to project a larger picture, the display signal source 100 (such as a display card) must have the ability to display the same picture on different displays at the same time, and make the picture horizontally or horizontally. The capability of vertically cutting and stretching and simultaneously supplying left and right or top and bottom images for display, at this time, the display signal source 100 must activate the horizontal/vertical stretching driving function.
在传统的个人电脑上，使用水平/垂直延伸功能的画面一般都会使用功能更强大的独立显示卡来产生，而个人电脑上的独立显示卡一般是基于个人电脑上的数字视频界面进行输出。On a traditional personal computer, images using the horizontal/vertical extension function are generally generated using a more powerful independent display card, and the independent display card on the personal computer is generally based on the digital video interface on the personal computer for output.
一般业界的显示装置(如投影机)多半采用高解析多媒体界面来接收信号。然而，现有技术中当显示信号源(如独立显示卡)读取投影机上对应高解析多媒体界面的EDID时，显示信号源将投影机判断为HDMI装置并对应一般使用需求，根据HDMI装置所存有的EDID关闭水平/垂直延伸功能(即不支援水平/垂直延伸)，而使得大画面无法使以水平/垂直显示方式同时通过多台显示装置(投影机)进行显示。因此，本发明文件提出动态调整显示设置标签的方法来提高显示装置的使用弹性。In general, most display devices (such as projectors) in the industry use a high-resolution multimedia interface to receive signals. However, in the prior art, when the display signal source (such as an independent display card) reads the EDID corresponding to the high-resolution multimedia interface on the projector, the display signal source judges the projector as an HDMI device and corresponds to general use requirements. The EDID of the EDID closes the horizontal/vertical extension function (that is, does not support horizontal/vertical extension), so that the large screen cannot be displayed by multiple display devices (projectors) at the same time in the horizontal/vertical display mode. Therefore, the present document proposes a method of dynamically adjusting display setting tags to improve the flexibility of use of the display device.
请参阅图2A，其绘示根据本发明的第一实施例中一种显示控制方法的流程示意图。显示控制方法用以控制显示装置动态调整显示设置标签，于此实施例中，与显示装置连接的显示信号源可根据显示设置标签选择性地提供符合第一影像传输协议或第二影像传输协议的显示信号。如图2A所示，显示控制方法首先执行步骤S200，判断显示装置是否开启一预定显示功能，于第一实施例中，预定显示功能即为边缘融合功能。Please refer to FIG. 2A , which is a schematic flowchart of a display control method according to the first embodiment of the present invention. The display control method is used to control the display device to dynamically adjust the display setting label. In this embodiment, the display signal source connected to the display device can selectively provide the first image transmission protocol or the second image transmission protocol according to the display setting label. Show signal. As shown in FIG. 2A , the display control method first executes step S200 to determine whether a predetermined display function is enabled on the display device. In the first embodiment, the predetermined display function is an edge blending function.
接着，显示控制方法便可执行步骤S210，根据该显示装置的边缘融合功能是否开启，选择性地将符合第一影像传输协议的该显示设置标签或符合第二影像传输协议的该显示设置标签写入显示装置的储存单元。于此例中，第一影像传输协议可为高解析多媒体界面(High-DefinitionMultimediaInterface,HDMI)协议，而第二影像传输协议可为数字视频界面(DigitalVisualInterface,DVI)协议。Then, the display control method can execute step S210, according to whether the edge blending function of the display device is enabled, selectively write the display setting tag conforming to the first video transmission protocol or the display setting tag conforming to the second video transmission protocol. into the storage unit of the display device. In this example, the first image transmission protocol may be a High-Definition Multimedia Interface (HDMI) protocol, and the second image transmission protocol may be a Digital Visual Interface (DVI) protocol.
步骤S210又分为步骤S211与步骤S212。如图2A所示，当预定显示功能(于此例中为边缘融合功能)未开启时，显示控制方法执行步骤S211，将符合第一影像传输协议的显示设置标签写入显示装置的储存单元。Step S210 is divided into step S211 and step S212. As shown in FIG. 2A , when the predetermined display function (in this example, the edge blending function) is not enabled, the display control method executes step S211 to write the display setting tag conforming to the first video transmission protocol into the storage unit of the display device.
其中，符合第一影像传输协议的显示设置标签包含供应商专用数据块(VendorSpecificDataBlock,VSDB)。Wherein, the display setting tag conforming to the first image transmission protocol includes a Vendor Specific Data Block (VSDB).
而在高解析多媒体界面协议在原本的显示设置标签基础下，进一步制定延伸显示能力识别数据(extensionblockEDID,e-EDID)，延伸的部分包含时间参数、端子状态信息、显示器支援时脉、支援格式以及供应商专用数据块，其中，供应商专用数据块为高解析多媒体界面协议的下延伸版本的EDID所独有的。In the high-resolution multimedia interface protocol, on the basis of the original display setting label, the extended display capability identification data (extension block EDID, e-EDID) is further developed. The extended part includes time parameters, terminal status information, display support clock, support format and The vendor-specific data block, wherein the vendor-specific data block is unique to the EDID of the down-extended version of the high-resolution multimedia interface protocol.
另一方面，当预定显示功能(于此例中为边缘融合功能)开启时，显示控制方法执行步骤S212，将符合第二影像传输协议(如DVI)的显示设置标签(如EDID)写入显示装置的储存单元，符合第二影像传输协议(如DVI)的显示设置标签未包含供应商专用数据块。On the other hand, when the predetermined display function (in this example, the edge blending function) is turned on, the display control method executes step S212 to write the display setting tag (such as EDID) conforming to the second image transmission protocol (such as DVI) into the display In the storage unit of the device, the display setting tag conforming to the second video transmission protocol (such as DVI) does not contain a vendor-specific data block.
根据上述显示控制方法中的步骤S200至步骤S212，已完成选择性写入不同影像传输协议的显示设置标签的程序。According to the steps S200 to S212 in the above display control method, the process of selectively writing display setting tags of different image transmission protocols has been completed.
接着于部份实施例中，显示控制方法可进一步包含步骤S220，由显示信号源读取显示设置标签并选择性地提供符合第一影像传输协议或第二影像传输协议的显示信号至显示装置。其中，步骤S220又可分为步骤S221、步骤S222、步骤S223、步骤S224以及步骤S225。Next, in some embodiments, the display control method may further include step S220 of reading the display setting tag from the display signal source and selectively providing a display signal conforming to the first video transmission protocol or the second video transmission protocol to the display device. Wherein, step S220 can be divided into step S221, step S222, step S223, step S224 and step S225.
首先显示控制方法执行步骤S221，将显示装置连接至显示信号源(如个人电脑、显示系统伺服器或影像显示卡)。接着，执行步骤S222，显示信号源由显示装置的储存单元读取显示设置标签。Firstly, the display control method executes step S221 to connect the display device to a display signal source (such as a personal computer, a display system server or a video display card). Next, step S222 is executed, and the display signal source reads the display setting tag from the storage unit of the display device.
最后，执行步骤S223，判断显示设置标签是否包含该供应商专用数据块。Finally, step S223 is executed to determine whether the display setting tag contains the vendor-specific data block.
一般来说，为了确认接收端(显示装置)是否为HDMI设备，显示信号源需要检查接收端(显示装置)的EDID，是否存在供应商专用数据块(VSDB)叙述。接收端(显示装置)会自动回应，只要显示信号源接到相关回应，就将接收端(显示装置)认定为HDMI设备，否则就会被认为所连接的是DVI设备。此供应商专用数据块(VSDB)叙述可以让显示信号源有效办识显示装置的型式，以便传送正确格式的显示信号给接收端(显示装置)显示。Generally speaking, in order to confirm whether the receiving end (display device) is an HDMI device, the display signal source needs to check the EDID of the receiving end (display device), and whether there is a Vendor Specific Data Block (VSDB) description. The receiving end (display device) will respond automatically. As long as the display signal source receives the relevant response, the receiving end (display device) will be recognized as an HDMI device, otherwise it will be considered as a DVI device. The Vendor Specific Data Block (VSDB) description allows the display signal source to effectively identify the type of the display device, so as to transmit the display signal in the correct format to the receiving end (display device) for display.
当显示设置标签包含供应商专用数据块，则执行步骤S224，显示信号源输出符合第一影像传输协议(如HDMI)的显示信号至显示装置。When the display setting tag contains the provider-specific data block, step S224 is executed, and the display signal source outputs a display signal conforming to the first image transmission protocol (such as HDMI) to the display device.
当显示设置标签未包含供应商专用数据块，则执行步骤S225，显示信号源输出符合第二影像传输协议(如DVI)的显示信号至显示装置。When the display setting tag does not contain the provider-specific data block, step S225 is executed, and the display signal source outputs a display signal conforming to the second video transmission protocol (such as DVI) to the display device.
由图2A所示的第一实施例中可知，当显示装置开启预定显示功能(即边缘融合功能)，便写入符合第二影像传输协议(DVI)的显示设置标签至显示装置的储存单元，由此动态将显示装置的显示设置标签设置为符合第二影像传输协议(DVI)，如此一来，显示信号源便可正常开启预定显示功能(即边缘融合功能)。由此，可避免因显示信号源将显示装置(投影机)判断为HDMI装置并关闭边缘融合功能的情况发生。From the first embodiment shown in FIG. 2A, it can be seen that when the display device turns on the predetermined display function (ie, the edge blending function), it writes the display setting tag conforming to the second video transmission protocol (DVI) to the storage unit of the display device, Thus, the display setting tag of the display device is dynamically set to comply with the second video transmission protocol (DVI), so that the display signal source can normally enable the predetermined display function (ie, the edge blending function). In this way, the situation that the display device (projector) is determined to be an HDMI device due to the display signal source and the edge blending function is disabled can be avoided.
也就是说，第一实施例中显示控制方法可根据显示装置上预定显示功能(即边缘融合功能)是否开启而动态调整显示装置的显示设置标签。That is to say, the display control method in the first embodiment can dynamically adjust the display setting label of the display device according to whether the predetermined display function (ie, the edge blending function) on the display device is enabled.
然而，本发明的显示控制方法中的预定显示功能并不仅限于第一实施例中所揭露的边缘融合功能。请参阅图2B，其绘示根据本发明的第二实施例中一种显示控制方法的流程示意图。However, the predetermined display function in the display control method of the present invention is not limited to the edge blending function disclosed in the first embodiment. Please refer to FIG. 2B , which is a schematic flowchart of a display control method according to a second embodiment of the present invention.
于第二实施例中，预定显示功能也可为使用者通过显示装置的屏幕视控界面(on-screendisplay,OSD)或通讯连接界面而切换的显示装置的任一种显示功能，例如，使用者通过屏幕视控界面/通讯连接界面而调整了显示装置的显示设定(如扫描频率、解析度等)或操作模式(单画面操作、多画面合并、画面放大/缩小等)等各种显示功能。如图2B所示，显示控制方法执行步骤S201，判断使用者屏幕视控界面或通讯连接界面所指定其他显示功能的开启与否，随后依据上述显示功能开启与否，通过步骤S210与步骤S220的动态变更显示设置标签的内容，使显示设置标签符合不同的影像传输协议，其控制细节与第一实施例大致相同，在此不另赘述。于第二实施例中，使用者可主动通过屏幕视控界面(on-screendisplay,OSD)或通讯连接界面(如RS-232界面)动态调整显示装置上的显示设置标签。In the second embodiment, the predetermined display function can also be any display function of the display device switched by the user through the on-screen display (OSD) or communication connection interface of the display device, for example, the user Various display functions such as the display setting (such as scanning frequency, resolution, etc.) or operation mode (single-screen operation, multi-screen merging, screen enlargement/reduction, etc.) of the display device are adjusted through the screen visual control interface/communication connection interface . As shown in FIG. 2B , the display control method executes step S201 to determine whether other display functions designated by the user’s screen visual control interface or communication connection interface are enabled or not, and then according to whether the above display functions are enabled or not, through steps S210 and S220 The content of the display setting tag is dynamically changed so that the display setting tag complies with different image transmission protocols. The control details are roughly the same as those in the first embodiment, and will not be repeated here. In the second embodiment, the user can actively adjust the display setting labels on the display device through an on-screen display (OSD) or a communication connection interface (such as an RS-232 interface).
也就是说，本发明的显示控制方法可根据显示装置上的各种预定显示功能开启与否而动态调整显示设置标签的内容，并不仅限于边缘融合功能。That is to say, the display control method of the present invention can dynamically adjust the content of the display setting label according to whether various predetermined display functions on the display device are enabled or not, and is not limited to the edge blending function.
接着，请一并参阅图3，其绘示根据本发明的第三实施例中一种显示控制方法的流程示意图。于图3所示的第三实施例中，显示控制方法可根据显示信号源发送至显示装置的显示信号的特性，来动态调整显示装置中的显示设置标签。显示设置标签可为显示能力识别数据(Extendeddisplayidentificationdata,EDID)。Next, please refer to FIG. 3 , which shows a schematic flowchart of a display control method according to a third embodiment of the present invention. In the third embodiment shown in FIG. 3 , the display control method can dynamically adjust the display setting tags in the display device according to the characteristics of the display signal sent from the display signal source to the display device. The display setting tag may be display capability identification data (Extended display identification data, EDID).
于此实施例中，显示装置(如投影机)与显示信号源(如个人电脑、显示系统伺服器或影像显示卡)连接。如图3所示，显示控制方法首先执行步骤S300，由显示信号源发送显示信号至显示装置。In this embodiment, a display device (such as a projector) is connected to a display signal source (such as a personal computer, a display system server or a video display card). As shown in FIG. 3 , the display control method first executes step S300 , in which a display signal source sends a display signal to a display device.

In this embodiment, the first image transmission protocol may be a High-Definition Multimedia Interface (HDMI) protocol.
于步骤S310中，显示控制方法可通过判断显示信号是否包含音频部份，来得知显示信号是否基于第一影像传输协议。若显示信号包含音频部份，则判断显示信号是基于第一影像传输协议，即HDMI协议。In step S310, the display control method can know whether the display signal is based on the first video transmission protocol by judging whether the display signal includes an audio part. If the display signal includes an audio part, it is determined that the display signal is based on the first image transmission protocol, ie, the HDMI protocol.

As shown in FIG. 3 , when the display signal is based on the first video transmission protocol, the display control method executes step S321 to write the display setting tag (EDID) conforming to the first video transmission protocol (HDMI) into the storage unit of the display device. The display setting tag conforming to the first image transmission protocol includes a vendor specific data block (VendorSpecificDataBlock, VSDB).
另一方面，当显示信号非基于第一影像传输协议时，显示控制方法执行步骤S322，将符合第二影像传输协议(DVI)的显示设置标签(EDID)写入显示装置的储存单元。符合第二影像传输协议的显示设置标签则未包含供应商专用数据块。On the other hand, when the display signal is not based on the first video transmission protocol, the display control method executes step S322 to write the display setting tag (EDID) conforming to the second video transmission protocol (DVI) into the storage unit of the display device. Display settings tags conforming to the second image transfer protocol do not contain a vendor-specific data block.
接着，执行步骤S330，显示信号源由显示装置读取显示设置标签并选择性地开启与第一影像传输协议或第二影像传输协议相关的一显示功能。Next, step S330 is executed, the display signal source reads the display setting tag from the display device and selectively enables a display function related to the first video transmission protocol or the second video transmission protocol.
步骤S330又分为步骤S331、步骤S332以及步骤S333。Step S330 is divided into step S331, step S332 and step S333.
首先，显示控制方法执行步骤S331，显示信号源由该显示装置读取该显示设置标签。Firstly, the display control method executes step S331, and the display signal source reads the display setting tag from the display device.
接着，执行步骤S332，显示信号源判断显示设置标签是否包含供应商专用数据块。Next, step S332 is executed, and the display signal source judges whether the display setting tag contains a vendor-specific data block.
若显示设置标签包含供应商专用数据块，则执行步骤S333，显示信号源开启与第一影像传输协议相关的该显示功能。If the display setting tag includes the provider-specific data block, step S333 is executed, and the display signal source enables the display function related to the first image transmission protocol.
另一方面，若显示设置标签未包含供应商专用数据块，则执行步骤S334，显示信号源开启与第二影像传输协议相关的显示功能。On the other hand, if the display setting tag does not include the provider-specific data block, step S334 is executed, and the display signal source enables the display function related to the second image transmission protocol.
如此一来，此实施例中的显示控制方法可根据显示信号源发送至显示装置的显示信号的特性，来动态调整显示装置中的显示设置标签，以提高显示信号源与显示装置之间的相容性。In this way, the display control method in this embodiment can dynamically adjust the display setting label in the display device according to the characteristics of the display signal sent from the display signal source to the display device, so as to improve the correlation between the display signal source and the display device.
