Description
本發明關於一種視訊資料顯示裝置,尤其是在由複數個顯示面板所構成的顯示系統中,利用一組視訊資料驅動複數個顯示面板進行顯示的裝置。本發明還涉及此視訊資料顯示裝置的顯示方法。 The present invention relates to a device for displaying video information, especially in a display system composed of a plurality of display panels, a device for driving a plurality of display panels to display by using a set of video data. The present invention also relates to a display method of the video data display device.
當顯示系統中存在多個顯示面板時,為了讓各個顯示面板能夠分別顯示不同的畫面,一般而言需要使用多組不同的視訊資料來驅動不同的顯示面板。為此,顯示系統除了必須為每個顯示面板設置各自的顯示驅動電路外,還必須為每個顯示面板設置各自的視訊資料處理器,以利用視訊資料處理器分別接收並處理不同的顯示訊號,進而提供給不同的顯示驅動電路來驅動各個顯示面板。 When there are multiple display panels in the display system, in order to enable each display panel to display different images, generally, multiple sets of different video data need to be used to drive different display panels. To this end, the display system must not only set up its own display driving circuit for each display panel, but also set up its own video data processor for each display panel, so as to use the video data processor to receive and process different display signals respectively. Further, it is provided to different display driving circuits to drive each display panel.
然而,設置多個視訊資料處理器必然會增加顯示系統的成本。況且,顯示系統可能還需要對顯示訊號進行各種前處理(例如:解析度調整),來形成並提供多組不同的顯示資料以驅動各個顯示面板,這同樣也會造成顯示系統的成本增加。尤其在車用電子、物聯網或智慧家庭等領域時常需要應用僅顯示簡單資訊的多個顯示面板,在這些領域為了驅動多個顯示面板所耗費的成本儼然為業界亟需解決的問題。 However, setting up multiple video data processors will inevitably increase the cost of the display system. Moreover, the display system may also need to perform various preprocessing (eg, resolution adjustment) on the display signal to form and provide multiple sets of different display data to drive each display panel, which also increases the cost of the display system. Especially in the fields of automotive electronics, Internet of Things or smart home, it is often necessary to apply multiple display panels that only display simple information. In these fields, the cost of driving multiple display panels seems to be an urgent problem for the industry to solve.
鑑於此,本發明提供一種視訊資料顯示裝置,其可以讓複數個顯示面板透過一組視訊資料來顯示,故可解決上述問題。 In view of this, the present invention provides a video data display device, which can display a plurality of display panels through a set of video data, so as to solve the above problems.
本發明之目的,在於提供一種視訊資料顯示裝置及其顯示方法,其中雖使各個顯示驅動電路雖然由同一個視訊資料處理器接收相同視訊資料,然而透過各個顯示驅動電路的資料變換器分別對該視訊資料進行變換,即可分別形成不同的子視訊資料。據此,僅需要一組視訊資料搭配一個資料處理器即可驅動數個顯示面板顯示不同的畫面,而且不需要對顯示訊號進行解析度調整等前處理,能夠有效降低顯示系統的整體成本。 The object of the present invention is to provide a video data display device and a display method thereof, wherein although each display driving circuit receives the same video data by the same video data processor, the data converters of each display driving circuit respectively receive the same video data. The video data can be transformed to form different sub-video data. Accordingly, only one set of video data and one data processor are required to drive several display panels to display different images, and preprocessing such as resolution adjustment of display signals is not required, which can effectively reduce the overall cost of the display system.
本發明關於一種視訊資料顯示裝置,其包含一視訊資料處理器及數個顯示驅動電路。該視訊資料處理器輸出一視訊資料。該些顯示驅動電路分別耦接於該視訊資料處理器以接收該視訊資料。各該顯示驅動電路包含一資料變換器及一驅動訊號產生器。該資料變換器對該視訊資料進行變換以形成一子視訊資料並傳輸至該驅動訊號產生器。該資料變換器對該視訊資料進行以下三種處理的至少一種:將該視訊資料的資料進行取代、產生與該視訊資料不同的空白間隙資訊、產生新的空白間隙資訊***該視訊資料中。 The present invention relates to a video data display device, which includes a video data processor and a plurality of display driving circuits. The video data processor outputs a video data. The display driving circuits are respectively coupled to the video data processor to receive the video data. Each of the display driving circuits includes a data converter and a driving signal generator. The data converter transforms the video data to form a sub-video data and transmits it to the driving signal generator. The data converter performs at least one of the following three kinds of processing on the video data: replacing the data of the video data, generating blank space information different from the video data, and generating new blank space information and inserting it into the video data.

請參閱第1圖,其為本發明實施例之視訊資料顯示裝置1的架構圖。如圖所示,視訊資料顯示裝置1包含一視訊資料處理器(Video Processor)11及數個顯示驅動電路(Display Driver Circuit)12。該視訊資料處理器11分別耦接各該顯示驅動電路12。該視訊資料處理器11可輸出一視訊資料VD,並由各該顯示驅動電路12接收該視訊資料VD。該視訊資料顯示裝置1可供應用於包含數個顯示
面板21、22、23的顯示系統中,各該顯示驅動電路12分別耦接各該顯示面板21、22、23,以驅動各該顯示面板21、22、23顯示畫面。
Please refer to FIG. 1 , which is a structural diagram of a video data display device 1 according to an embodiment of the present invention. As shown in the figure, the video data display device 1 includes a
請一併參照第2圖所示,在本實施例中,各該顯示驅動電路12分別包含一資料接收器121、一資料變換器122及一驅動訊號產生器123。該資料接收器121由該視訊資料處理器11接收該視訊資料VD。並且,該資料接收器121可以對該視訊資料VD的介面標準格式進行轉換。舉例而言,若該視訊資料VD原先為高畫質多媒體介面(High Definition Multimedia Interface,HDMI)、低電壓差動訊號傳輸(Low Voltage Differential Signaling,LVDS/LDI)、OpenLDI或Serial R/G/B等格式,該資料接收器121可以將其轉換為RGB格式。其中,介面標準格式的種類繁多,故該資料接收器121轉換前後的介面標準格式並不以上述範例為限。
Please also refer to FIG. 2 , in this embodiment, each of the
該資料變換器122耦接於該資料接收器121,以接收經由該資料接收器121處理後的視訊資料VD’。然而,在本發明部分實施例中,若該視訊資料VD的介面標準格式不需要被轉換,亦可省略該資料接收器121,直接由該資料變換器122接收該視訊資料VD。該資料變換器122對該視訊資料VD’進行變換,所述變換至少包含以下三種處理的至少一種:將該視訊資料VD’的資料進行取代、產生與該視訊資料VD’不同的空白間隙(Blanking)資訊、產生新的空白間隙資訊***該視訊資料VD’中。該資料變換器122完成變換該視訊資料VD’後,係形成一子視訊資料SVD並傳輸至該驅動訊號產生器123。
The
該驅動訊號產生器123耦接於該資料變換器122,該資料變換器122完成變換該視訊資料VD’後,係形成一子視訊資料SVD並傳輸至該驅動訊號產生器123。該驅動訊號產生器123可接收該子視訊資料SVD,並依據該子視訊資
料SVD產生驅動顯示面板所需的驅動訊號DS(例如源極驅動訊號,甚至包含閘極驅動訊號或公共驅動訊號等)。藉此,驅動訊號DS即可用來驅動各該顯示面板21、22、23顯示該子視訊資料SVD。此外,在本發明部分實施例中,該驅動訊號產生器123還可以依據該子視訊資料SVD產生驅動顯示面板時所需的控制訊號(例如源極時序訊號或閘極時序訊號等)。
The driving
請參照第3圖所示,該顯示面板21耦接於該顯示驅動電路12,因此,該驅動訊號產生器123所生成的驅動訊號DS(在部分實施例中還可以包含控制訊號)即可用來驅動顯示面板21,以顯示子視訊資料SVD。在本實施例中由於存在三個顯示面板21、22、23,藉由各該顯示驅動電路12的資料變換器122分別對該視訊資料VD’進行變換,即可分別形成不同的子視訊資料SVD,故得以驅動各該顯示面板21、22、23顯示不同的畫面。
Referring to FIG. 3, the
以下將對該資料變換器122所執行的三種變換進行詳細說明:
The three transformations performed by the
請參照第4圖所示,其為一實施例之資料變換器122對該視訊資料VD’所執行的變換。該視訊資料VD’包含一畫面資料DD及一空白間隙區域BA,其中該畫面資料DD即為欲在顯示面板上顯示的內容,該空白間隙區域BA則不具有顯示資料,但為各種介面標準格式都需要的緩衝區域。在本發明中,各該顯示面板21、22、23可供顯示完整或一部分的畫面資料DD,例如該顯示面板21就用來在一顯示區域DA1中顯示一部分的畫面資料DD。該資料變換器122接收該視訊資料VD’後,可以將該視訊資料VD’於顯示區域DA1以外的資料進行取代,以捨棄位於顯示區域DA1以外的畫面資料DD及/或空白間隙區域BA。據此,只有一部分的畫面資料DD會保留在顯示區域DA1中。
Please refer to FIG. 4 , which is the transformation performed by the
另一方面,在本實施例中,由於在顯示區域DA1右側(依圖面而言)會保有被截斷的畫面資料DD,而通常介面標準格式會需要留有一空白間隙進行緩衝才能正常顯示,因此該資料變換器122還可以產生與該視訊資料VD’不同的空白間隙資訊,並且置換在顯示區域DA1右側的畫面資料DD。據此,經由該資料變換器122變換所形成的子視訊資料SVD1亦包含一子畫面資料DD1及一空白間隙區域BA1,該子畫面資料DD1為該視訊資料VD’一部分的畫面資料DD,且該空白間隙區域BA1會圍繞該子畫面資料DD1,使得該驅動訊號產生器123能夠正確依據該子視訊資料SVD1驅動該顯示面板21進行顯示。
On the other hand, in this embodiment, since the cut-off image data DD is kept on the right side of the display area DA1 (in terms of the drawing), and the standard interface format usually requires a blank space for buffering to be displayed normally, so The
請參照第5圖所示,類似地,另一個資料變換器122在接收同一個視訊資料VD’後,也可以將該視訊資料VD’於顯示區域DA2以外的資料進行取代,而保留在該顯示區域DA2中的畫面資料DD和保留在前述顯示區域DA1中的子畫面資料DD1是畫面資料DD的不同部分。然而,除了產生與該視訊資料VD’不同的空白間隙資訊來置換位在顯示區域DA2左、右兩側的畫面資料DD外,雖然顯示區域DA2下側(依圖面而言)本已保有空白間隙,該資料變換器122仍然可以利用與該視訊資料VD’不同的空白間隙資訊來置換位在顯示區域DA2下側的畫面資料DD。據此,經由該資料變換器122變換所形成的子視訊資料SVD2會包含更小範圍的一子畫面資料DD2。
Please refer to FIG. 5. Similarly, after receiving the same video data VD', another
請參照第6圖所示,相較於前述第5圖的實施例,倘若該子視訊資料SVD2需要顯示於尺寸較大的顯示面板22,然而所需顯示的子畫面資料DD2並未增加時,該資料變換器122僅需簡單透過框選較大的顯示區域DA2,再利用與該視訊資料VD’不同的空白間隙資訊來置換不需要的顯示資料DD,即可形成具有相同子畫面資料DD2及較大空白間隙區域BA2的適當子視訊資料SVD2。
Referring to FIG. 6, compared with the embodiment of FIG. 5, if the sub-video data SVD2 needs to be displayed on the
請參照第7圖所示,其為另一實施例之資料變換器122對該視訊資料VD’所執行的變換。該資料變換器122除了執行前述變換外,還可以產生新的空白間隙資訊***該視訊資料VD’中。舉例而言,該資料變換器122將該視訊資料VD’於顯示區域DA1以外的資料進行取代後,可以直接產生新的空白間隙資訊***在顯示區域DA1右側(依圖面而言),而產生更大的顯示區域DA1’。據此,經由該資料變換器122變換所形成的子視訊資料SVD1會具有更大的顯示區域DA1’,在顯示區域DA1’中亦包含一子畫面資料DD1及圍繞該子畫面資料DD1的空白間隙區域BA1,使得該驅動訊號產生器123能夠正確依據該子視訊資料SVD1驅動該顯示面板21進行顯示。
Please refer to FIG. 7, which is the transformation performed by the
實際上,由於本發明實施例的資料變換器122能夠進行將該視訊資料VD’的資料進行取代、產生與該視訊資料VD’不同的空白間隙資訊、產生新的空白間隙資訊***該視訊資料VD’中等三種處理的一種或多種,實際應用於顯示系統中時,無論數個顯示面板21、22、23的尺寸或所應顯示的內容為何,各該資料變換器122都能輕易產生對應的子視訊資料SVD來讓驅動訊號產生器123驅動各該顯示面板21、22、23。如第8圖所示,該資料變換器122將該視訊資料VD’於顯示區域DA2以外的資料進行取代後,除可以以利用與該視訊資料VD’不同的空白間隙資訊來置換位在顯示區域DA2左側、下側的畫面資料DD,還可以再產生新的空白間隙資訊***在顯示區域DA2右側(依圖面而言),以產生對應具有更大的顯示區域DA2’的子視訊資料SVD2來讓驅動訊號產生器123驅動該顯示面板22。
In fact, because the
值得注意的是,各該資料變換器122如何變換該視訊資料VD’的模式,可以預先儲存於非揮發性記憶體中,且可以儲存多組不同的變換模式,而得
以經由一外部控制訊號選用各該資料變換器122的變換模式,使得應用本發明各實施例之視訊資料顯示裝置1的產品設計靈活度更高。此外,前述子畫面資料的解析度會小於或等於該視訊資料之畫面資料的解析度,舉例而言,當該視訊資料之畫面資料的解析度為600x200,前述子畫面資料的解析度可以為200x200。
It is worth noting that how each
綜上所述,藉由實施本發明之視訊資料顯示裝置,各個顯示驅動電路雖然由同一個視訊資料處理器接收視訊資料,然而透過各個顯示驅動電路的資料變換器分別對該視訊資料進行變換,即可分別形成不同的子視訊資料,以驅動各該顯示面板顯示不同的畫面。據此,相較於現有技術需要設置多個視訊資料處理器以使用多組不同的視訊資料來驅動不同的顯示面板,採用本發明視訊資料顯示裝置僅需要一組視訊資料搭配一個視訊資料處理器即可達到相同效果,而且不需要對顯示訊號進行解析度調整等前處理,能夠有效降低顯示系統的整體成本。 To sum up, by implementing the video data display device of the present invention, although each display driving circuit receives the video data by the same video data processor, the video data is converted by the data converters of each display driving circuit, respectively. Different sub-video data can be formed respectively to drive each of the display panels to display different images. Accordingly, compared with the prior art, which requires multiple video data processors to use multiple sets of different video data to drive different display panels, the video data display device of the present invention only requires one set of video data and one video data processor. The same effect can be achieved, and the display signal does not need to be pre-processed such as resolution adjustment, which can effectively reduce the overall cost of the display system.
以上所述僅為本發明之較佳實施例,凡依本發明申請專利範圍所做之均等變化與修飾,皆應屬本發明之涵蓋範圍。 The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
