The control unit 126 can receive and process a data stream, and can at least part of the data stream. Transfer to one of the electrodes of the display panel 127. The display panel 127 can include the matrix substrate 122 described above. In addition, the data stream can be a digital data stream or a digital file stream, and can be touch information, command information, identification information, transaction information, advertising information, preferential information, file information or other information. The electrode of the display panel 127 can be a single electrode (which can be one or more electrodes) and is independent of the pixel matrix or at least one of a plurality of row electrodes or a plurality of column electrodes of the pixel matrix. In addition, the control unit 126 can split and process the data stream into at least one sub-data stream and transmit the same to the electrodes of the display panel 127 of the matrix display device 12, and the operating device 11 can receive the sub-data streams. The processing of the data stream may include a series-to-parallel conversion, an over-code, an encryption, a header (including a data size, a check code, a serial number, a tracking data), a transmission start flag, and/or End tag, etc. The difference from the general communication transmission mode is that different electrodes can be used simultaneously as transmission sources (multi-communication pipes) for transmission. These communication pipes can use space isolation or modulation techniques to reduce interference between them. Note that the stream-to-parallel conversion method of the data stream may be sequential (for example, dividing the first to Nth bits of the data stream to the first substream, and the N+1th to Mth bits to the second substream) , ..., etc.), interleaving (for example, the first bit is assigned to the first substream, the second bit is assigned to the second substream, ..., the Nth bit is assigned to the last substream, N+1 The bit is assigned to the first substream, ... and so on, or a combination of the two.
請再參照圖1及圖2B所示,當使用者利用操作裝置11在矩陣顯示裝置12之顯示面121上操作時,部分之資料流可從矩陣顯示裝置12之矩陣基板122藉由電磁效應耦合(例如電容或電感耦合)至操作裝置11。於此,耦合係以無線方式將數位資訊(即0或1)自矩陣顯示裝置12傳輸至操作裝置11。而操作裝置11接收自顯示面121上傳送之資料流時,操作裝置11藉由所接收到的資料流進行反向處理以得到傳送之資訊。其中,接收資料的方式係藉由操作裝置11靠近或接觸矩陣顯示裝置12之顯示面121,以將訊號藉由電磁作用耦合至操作裝置。Referring to FIG. 1 and FIG. 2B again, when the user operates on the display surface 121 of the matrix display device 12 by using the operating device 11, part of the data stream can be coupled from the matrix substrate 122 of the matrix display device 12 by electromagnetic effect. (for example capacitive or inductive coupling) to the operating device 11. Here, the coupling wirelessly transmits digital information (ie, 0 or 1) from the matrix display device 12 to the operating device 11. When the operating device 11 receives the data stream transmitted from the display surface 121, the operating device 11 performs reverse processing by the received data stream to obtain the transmitted information. The method of receiving data is to approach or contact the display surface 121 of the matrix display device 12 by the operating device 11 to couple the signal to the operating device by electromagnetic action.
另外,若利用的是畫素矩陣中的行電極或列電極來傳送部分的資料流,則可與矩陣顯示裝置12之顯示資料傳送分開於不同時間傳送,例如於一顯示資料傳送結束之後或於一顯示資料傳送開始之前傳送至操作裝置11。注意於此顯示資料與部分資料流僅為代表有兩種不同目的之資料在電極上傳送,並不限制顯示資料耦合至操作裝置或是顯示部分資料流。換言之,矩陣顯示裝置12可於一個圖框(frame)畫面結束之後,並於下一圖框畫面開始之前,或於顯示一個圖框畫面的期間,將子資料流開始傳送至操作裝置11。需注意的是,若是利用於畫素矩陣外的獨立電極來進行資料流的傳送時,則可不用與圖框畫面傳送的時間配合。In addition, if a row electrode or a column electrode in the pixel matrix is used to transmit a part of the data stream, the data transmission with the matrix display device 12 can be transmitted at different times, for example, after the end of a display data transmission or A display data transfer is transmitted to the operating device 11 before the start of transmission. Note that the display data and part of the data stream are only transmitted on the electrodes for data representing two different purposes, and do not limit the display data to the operating device or display part of the data stream. In other words, the matrix display device 12 can start transmitting the sub-stream to the operating device 11 after the end of one frame picture and before the start of the next picture frame or during the display of one picture frame. It should be noted that if the separate electrodes outside the pixel matrix are used for data stream transmission, the time required for transmission on the frame screen may not be matched.
此外,當完成資料流傳送至操作裝置11後,矩陣顯示裝置12可至少顯示一完整或部分的圖框畫面。換言之,資料流傳送結束的時間點可以位於一圖框畫面結束之後,並於下一圖框畫面開始顯示之前,或於一圖框畫面的期間,於此,並不加以限制。另外,於資料流開始耦合之前,矩陣顯示裝置12可以用至少一圖框畫面顯示資料流準備傳送至操作裝置11;另外,於資料流結束傳送之後,矩陣顯示裝置12也可以用至少一圖框畫面顯示資料流結束傳送。換言之,在矩陣顯示裝置12開始傳輸第一個資料流之前及最後一個資料流結束傳輸之後,矩陣顯示裝置12均可顯示提示畫面,以提醒使用者注意。另外,在資料流的傳輸期間,矩陣顯示裝置12亦可以在顯示畫面中標示出用於傳輸的電極區域範圍,以方便操作裝置11進行訊號的耦合。In addition, after the data stream is transmitted to the operating device 11, the matrix display device 12 can display at least one complete or partial frame picture. In other words, the time point at which the data stream transmission ends may be located after the end of a picture frame screen, and before the start of the next picture frame picture, or during the period of a picture frame, and is not limited thereto. In addition, before the data stream starts to be coupled, the matrix display device 12 can display the data stream to be transmitted to the operating device 11 by using at least one frame screen; and, after the data stream ends, the matrix display device 12 can also use at least one frame. The screen displays the end of the data stream. In other words, the matrix display device 12 can display a prompt screen to remind the user of the attention before the matrix display device 12 starts transmitting the first data stream and after the last data stream ends the transmission. In addition, during the transmission of the data stream, the matrix display device 12 may also indicate the range of the electrode regions for transmission in the display screen to facilitate the coupling of the signals by the operating device 11.
以下,以液晶顯示裝置之薄膜電晶體基板(TFT substrate)作為矩陣基板122來說明子資料流是如何從矩陣顯示裝置12之行電極或列電極耦合至操作裝置11。Hereinafter, a thin film transistor substrate (TFT substrate) of a liquid crystal display device is used as the matrix substrate 122 to explain how the substream is coupled from the row electrode or the column electrode of the matrix display device 12 to the operation device 11.

Further, the matrix 124 may further comprise a plurality of transistors T 11 ~ T MN, these transistors T 11 ~ T MN respectively such row electrodes S 1 ~ S M, these column electrodes D 1 ~ D N, and such The pixel electrodes E 11 to E MN are electrically connected. Here, the row electrodes S 1 to S M are exemplified by scanning lines, and the column electrodes D 1 to D N are exemplified by data lines. Of course, the row electrodes S 1 to S M may be data lines, and the column electrodes D 1 may be used. ~D N is the scan line. In addition, a driving module can be further disposed on the substrate 123, and includes a data driving circuit, a scanning driving circuit, a timing control circuit (not shown), and a gamma correction circuit (not shown), which can be driven by the driving module. The LCD panel displays the image. Since the drive module is a conventional technology for driving images, it will not be described here. In addition, the matrix substrate of this aspect is merely illustrative and is not intended to limit the present invention. The focus of this embodiment is that the sub-data stream is transferred from the matrix substrate 122 to the operating device 11 by at least one of the row electrodes S 1 to S M and/or the column electrodes D 1 to D N .
在本實施例中,列電極D1 ~DN 除了可傳送一般圖框畫面之顯示資料訊號之外,於此更可用以傳送子資料流。例如,在顯示訊號上直接疊加一高於顯示訊號頻率之子資料流或在其傳送顯示資料訊號的空檔時間,例如所有行電極S1 ~SM 掃描完後在接續下一次掃描之前的時間(圖框畫面與圖框畫面之間的空檔時間);或是在一條行電極掃描完成且在下一條開始掃描之前;或是在每一條行電極掃描時間內藉縮短顯示資料並在傳送顯示資料訊號之前等。於此,子資料流可由擴展時序控制(T-con)電路的功能以及資料或掃描驅動電路來提供,以簡化電路設計。In this embodiment, the column electrodes D 1 -D N can be used to transmit the sub-data stream in addition to the display data signal of the general frame picture. For example, a sub-stream that is higher than the display signal frequency or a neutral time at which the display data signal is transmitted is directly superimposed on the display signal, for example, the time before all the row electrodes S 1 to S M are scanned after the next scan is continued ( The gap time between the frame screen and the frame screen); either before a row electrode scan is completed and before the next scan is started; or during each row electrode scan time, the display data is shortened and the data signal is transmitted. Waiting before. Here, the sub-stream can be provided by the function of the extended timing control (T-con) circuit and the data or scan drive circuit to simplify the circuit design.
請參照圖4所示,其為圖3中之相鄰二行電極與相鄰二列電極的訊號示意圖。在此以每一列電晶體被開啟進行顯示資料顯入時同時可進行資料流傳送為例說明,要注意的是,電晶體被開啟與否並非必要,亦可在電晶體關閉狀態下進行資料流傳送,此時各子資料流可分別傳送於列電極或行電極上。行電極S1 ~SM 分別傳送掃描訊號SS依序使每一列的電晶體開啟,而在每一列電晶體被開啟的時間中,各列電極D1 ~DN 分別傳送子資料流ES與顯示資料訊號DS。在本實施例中,如圖4所示,在行電極SM-1 傳送其掃描訊號SSM-1 時,全部的列電極D1 ~DN 係傳送子資料流ESM-1 ;在行電極SM 傳送其掃描訊號SSM 時,全部的列電極D1 ~DN 係傳送子資料流ESM 。在圖4中,此子資料流ESM-1 、ESM 是以與顯示資料訊號DS不同電壓位準方式標示之,實施時亦可以相同之位準為之。如此,列電極D1 ~DN 隨著行電極S1 ~SM 傳送掃描訊號SS1 ~SSM 時,可分別傳送第一個資料流ES1 至第M個子資料流ESM ,以將資料流ES的至少一部分耦合至操作裝置11。Please refer to FIG. 4 , which is a schematic diagram of signals of adjacent two rows of electrodes and adjacent two columns of electrodes in FIG. 3 . Here, as each column of transistors is turned on for display data display, data flow can be simultaneously transmitted as an example. It should be noted that it is not necessary to turn on or off the transistor, and the data flow can be performed in the state where the transistor is off. Transfer, at this time each sub-stream can be transmitted to the column or row electrode respectively. The row electrodes S 1 to S M respectively transmit the scanning signals SS to sequentially turn on the transistors of each column, and in the time when each column of the transistors is turned on, the column electrodes D 1 to D N respectively transmit the sub-stream ES and display. Information signal DS. In this embodiment, as shown in FIG. 4, when the row electrode S M-1 transmits its scanning signal SS M-1 , all the column electrodes D 1 ~ D N transmit the sub-data stream ES M-1 ; S M which the electrode transfer scan signals SS M, all of the column electrodes D 1 ~ D N sub-system transport data stream ES M. In FIG. 4, the sub-streams ES M-1 and ES M are marked in different voltage levels than the display data signal DS, and may be implemented in the same level. In this manner, when the column electrodes D 1 to D N transmit the scanning signals SS 1 to SS M along with the row electrodes S 1 to S M , the first data stream ES 1 to the Mth sub-data stream ES M can be respectively transmitted to At least a portion of the flow ES is coupled to the operating device 11.
需補充說明的是,圖4中顯示的子資料流ESM 及ESM-1 雖顯示為高準位的1,不過只是示意,當然,也可以使用低準位的0。另外,為了避免產生訊號的極性問題,該等子資料流的訊號本身可採用無直流成分之交流訊號。再者,子資料流ESM 及ESM-1 可分別包含一個位元的資料或是複數位元的資料,於此並不加以限制。除了如圖4中所有的列電極於同一圖框時間中均傳送相同子資料流的態樣外,各列電極D1 ~DN 也可以分別傳送不同的子資料流ES1 ~ESM ,亦可以數條列電極為一組來傳送同一個子資料流,例如列電極D1 ~D3 都傳送第一子資料流ES1 ,而列電極D4 ~D6 都傳送第二子資料流ES2 ;同樣的原則亦可適用於行電極所傳送之子資料流。此外,為了確保資料流傳送之正確性,也可於不同的時間重覆傳送子資料流,也就是,如果發現異常時可以再次進行相同子資料流的傳送,以確保操作裝置11接收資料的正確性。當然,列電極D1 ~DN 與行電極S1 ~SM 亦可另外傳送較複雜的子資料流,將於下面加以詳述。It should be added that the sub-streams ES M and ES M-1 shown in FIG. 4 are shown as high-level 1 , but are merely schematic. Of course, low-level 0 can also be used. In addition, in order to avoid the polarity problem of the signals, the signals of the sub-streams may themselves adopt an AC signal without a DC component. Furthermore, the sub-streams ES M and ES M-1 may contain one bit of data or a plurality of bits, respectively, and are not limited thereto. Except that all the column electrodes in FIG. 4 transmit the same sub-stream in the same frame time, the column electrodes D 1 -D N can also transmit different sub-streams ES 1 -ES M respectively . The same sub-stream may be transmitted by a plurality of column electrodes, for example, the column electrodes D 1 - D 3 both transmit the first sub-stream ES 1 , and the column electrodes D 4 - D 6 all transmit the second sub-stream ES 2 ; The same principle can also be applied to the sub-streams transmitted by the row electrodes. In addition, in order to ensure the correctness of data stream transmission, the sub-data stream can also be repeatedly transmitted at different times, that is, if an abnormality is found, the same sub-data stream can be transmitted again to ensure that the operating device 11 receives the data correctly. Sex. Of course, the column electrodes D 1 -D N and the row electrodes S 1 -S M may additionally transmit a more complicated sub-stream, which will be described in detail below.
此外,上述的調變方式係為振幅調變(Amplitude Modulation)技術,即是以振幅的高低來表示數位訊號的1或0,不過,也可使用頻率調變(Frequency Modulation)技術來表示數位訊號的1或0,例如可定義單位時間內有5個上下振幅的變化是為1,其餘則為0;或者使用相移調變(Phase Shift Modulation)技術,例如定義一個高準位加上一個低準位為0,而一個低準位加上一個高準位則為1。於此,其調變方式並不加以限制。另外,為避免鄰近電極之間的干擾,不同電極之間可以採用分時、分頻、分碼等技術。In addition, the above modulation method is an amplitude modulation (Amplitude Modulation) technology, that is, the amplitude of the digital signal is expressed as 1 or 0, but frequency modulation (Frequency Modulation) technology can also be used to represent the digital signal. 1 or 0, for example, can define 5 up and down amplitude changes in unit time is 1 and the rest is 0; or use phase shift modulation (Phase Shift Modulation) technology, such as defining a high level plus a low level The bit is 0, and a low level plus a high level is 1. Here, the modulation method is not limited. In addition, in order to avoid interference between adjacent electrodes, techniques such as time division, frequency division, and code division can be used between different electrodes.
當使用者拿著操作裝置11於矩陣顯示裝置12之顯示面121上操作時(例如碰觸到顯示面或靠近顯示面121),子資料流可從矩陣基板122之顯示面121藉由電容耦合至操作裝置11。由於本實施例係以列電極D1 ~DN 傳送子資料流ES為例,因此各列電極D1 ~DN 係作為電容耦合之其中一電極,而操作裝置11上具有電容耦合之另一電極。在操作裝置11藉由電容耦合接收到所有的子資料流ES之後,操作裝置11可將接收的子資料流ES組合,以得到完整的資料流,例如為一文字檔案、圖片檔案或一視聽檔案等等。例如,當操作裝置11為一門禁控制單元時,即可藉由矩陣顯示裝置12之顯示面121靠近操作裝置11操作時,使操作裝置11接收由矩陣顯示裝置12傳送之開門或鎖門的資訊,藉此可解除門禁或上鎖;當矩陣顯示裝置12為一公眾顯示看板(public display),操作裝置11為一手機或其他個人裝置時,藉由將操作裝置11靠近矩陣顯示裝置12之顯示面121,可將如廣告資訊、優惠資訊、地理資訊等等傳送至個人裝置帶走。When the user operates the display device 121 on the display surface 121 of the matrix display device 12 (for example, touching the display surface or near the display surface 121), the sub-stream can be capacitively coupled from the display surface 121 of the matrix substrate 122. To the operating device 11. Since the present embodiment uses the column electrodes D 1 -D N to transmit the sub-stream ES as an example, each of the column electrodes D 1 -D N serves as one of the capacitive couplings, and the operating device 11 has another capacitive coupling. electrode. After the operating device 11 receives all the sub-streams ES by capacitive coupling, the operating device 11 can combine the received sub-streams ES to obtain a complete data stream, such as a text file, a picture file or an audiovisual file. Wait. For example, when the operating device 11 is an access control unit, the operating device 11 can receive the information of opening or locking the door transmitted by the matrix display device 12 when the display surface 121 of the matrix display device 12 is operated close to the operating device 11. Thereby, the access control or unlocking can be released; when the matrix display device 12 is a public display, the operating device 11 is a mobile phone or other personal device, by bringing the operating device 11 closer to the display of the matrix display device 12 Face 121, such as advertising information, preferential information, geographic information, etc. can be transferred to a personal device to take away.
另外,請參照圖5所示,其為本發明之資料傳輸系統1之矩陣顯示裝置12的外觀示意圖。In addition, please refer to FIG. 5, which is a schematic diagram of the appearance of the matrix display device 12 of the data transmission system 1 of the present invention.
矩陣顯示裝置12更可包含一模式觸發元件128,一使用者或操作裝置11可觸發此模式觸發元件128,以啟動矩陣顯示裝置12進入一工作模式而開始發送資料流。以矩陣顯示裝置12為一個人之觸控顯示裝置為例,當使用者需要發送資料流時,才觸發模式觸發元件128,以啟動矩陣顯示裝置12進入工作模式而開始發送資料流。此時行電極或列電極可關閉全部或部分矩陣顯示裝置12之觸控及顯示功能,如此可以防止觸動螢幕造成誤動作,同時亦可節省電力。注意此模式觸發元件128之工作模式可以有多種態樣,如單次觸發後經一段時間即恢復之前的工作模式、每次觸發即改變工作模式、持續觸發下才維持工作模式等方式。模式觸發元件128不限定要在顯示區外,也可以與顯示面板或觸控面板整合,例如可為一機械開關、一觸控開關、一圖示(icon)等。The matrix display device 12 can further include a mode triggering component 128. A user or operating device 11 can trigger the mode triggering component 128 to initiate the matrix display device 12 to enter an operational mode to begin transmitting the data stream. Taking the matrix display device 12 as a human touch display device as an example, when the user needs to send a data stream, the mode triggering component 128 is triggered to start the matrix display device 12 to enter the working mode and start to send the data stream. At this time, the row electrode or the column electrode can turn off the touch and display functions of all or part of the matrix display device 12, thereby preventing the touch screen from causing malfunction and saving power. Note that the mode of operation of the trigger component 128 can have various modes, such as a working mode after a single trigger is restored after a period of time, a working mode is changed every time the trigger is triggered, and a working mode is maintained under a continuous trigger. The mode triggering component 128 is not limited to be outside the display area, and may be integrated with the display panel or the touch panel. For example, it may be a mechanical switch, a touch switch, an icon, or the like.
以下,請參照圖6A至圖6D所示,以分別說明控制單元126(圖6A至圖6D未顯示)將子資料流傳送至矩陣顯示裝置12列電極的複數態樣,當然,子資料流傳送至矩陣顯示裝置12之行電極或獨立電極或其組合的方式也可相同,於此不再贅述。其中,圖6A至圖6D分別為子資料流與列電極D1 ~DN 的傳送關係示意圖。6A to 6D, respectively, the control unit 126 (not shown in FIGS. 6A to 6D) transmits the sub-data stream to the complex state of the column electrode of the matrix display device 12, of course, the sub-data stream is transmitted. The manner of the row electrodes or the individual electrodes of the matrix display device 12 or a combination thereof may also be the same, and details are not described herein again. 6A to 6D are schematic diagrams showing the transmission relationship between the sub-data stream and the column electrodes D 1 to D N , respectively.
控制單元126可將一資料流分流成複數子資料流,且當矩陣顯示裝置12將全部的子資料流均耦合至操作裝置11時,操作裝置11可接收該等子資料流,並將該等子資料流組合成原始傳送的資料流。當然,操作裝置11也可只接收部分的資料流,該部分的資料流可包至少一子資料流、或是子資料流之一部分、或複數子資料流。其中,各子資料流可分別具有一個位元或複數位元的資料。另外,控制單元126除了將資料流分流處理成至少一子資料流的資訊外,亦可包含傳送的起始資訊或結束資訊,以供操作裝置11確認傳送的開始與結束。操作裝置11接收該等子資料流加上起始與結束傳送的資訊後,將結果處理成資料流。此外,子資料流也可包含矩陣顯示裝置12之識別資訊,例如廠牌、型號、序號等資訊,以供操作裝置11接收後的識別之用。The control unit 126 can split a data stream into a plurality of sub-data streams, and when the matrix display device 12 couples all of the sub-data streams to the operating device 11, the operating device 11 can receive the sub-data streams, and The sub-data streams are combined into the original transmitted data stream. Of course, the operating device 11 can also receive only part of the data stream, and the data stream of the portion can include at least one sub-data stream, or a part of the sub-data stream, or a plurality of sub-data streams. Each sub-data stream may have one bit or multiple bits of data, respectively. In addition, the control unit 126 may also include the transmitted start information or the end information in addition to the data stream being processed into the information of the at least one sub-stream for the operation device 11 to confirm the start and end of the transmission. The operating device 11 receives the sub-streams plus the information of the start and end of the transfer, and processes the result into a stream. In addition, the sub-data stream may also include identification information of the matrix display device 12, such as a brand name, a model number, a serial number, and the like, for the identification of the operation device 11 after receiving.
如圖6A所示,在本實施例中,控制單元126係將資料流區分為複數子資料流,且每一子資料流具有至少一位元的資料。於此,係以每一子資料流只有一個位元的資料為例。當然,於其它的實施例中,每一子資料流也可具有複數個位元。另外,於一時間(例如可為一行電極掃描時間、或於一圖框時間內、或為一圖框時間與另一圖框時間之間),控制單元126將子資料流(例如第一子資料流ES1 )之位元資料分別傳送至所有的列電極D1 ~DN 。As shown in FIG. 6A, in the present embodiment, the control unit 126 divides the data stream into a plurality of sub-data streams, and each sub-data stream has at least one bit of data. Here, for example, the data of only one bit per sub-stream is taken as an example. Of course, in other embodiments, each substream may also have a plurality of bits. In addition, at a time (for example, one row of electrode scan time, or one frame time, or between one frame time and another frame time), the control unit 126 may stream the sub-data (eg, the first sub- The bit data of the data stream ES 1 ) is transmitted to all of the column electrodes D 1 to D N , respectively .
另外,如圖6B所示,於另一時間時,控制單元126可將另一子資料流(例如第二子資料流ES2 )之位元資料分別傳送所有列電極D1 ~DN ,以此類推。換言之,控制單元126可於一個時間內傳送一個子資料流至所有的列電極D1 ~DN ,並於另一個時間內傳送另一個子資料流至所有的列電極D1 ~DN 。當所有的子資料流分別藉由矩陣顯示裝置12之列電極D1 ~DN 傳送,且全部傳送至操作裝置11後,操作裝置11再將其組合成完整的資料。由於控制單元126將子資料流之位元資料分別傳送至矩陣顯示裝置12的所有列電極D1 ~DN ,因此,不論操作裝置11於矩陣顯示裝置12之顯示面121的哪個位置操作,操作裝置11均可接收到子資料流之位元資料而較不會發生遺漏的現象。In addition, as shown in FIG. 6B, at another time, the control unit 126 may transmit the bit data of another sub-stream (for example, the second sub-stream ES 2 ) to all of the column electrodes D 1 -D N , respectively. This type of push. In other words, the control unit 126 can transmit one sub-stream to all of the column electrodes D 1 -D N in one time and another sub-stream to all of the column electrodes D 1 -D N in another time. When all the sub-data stream are listed 12 of electrodes D 1 ~ D N matrix display by transmitting, to the operator and all the apparatus 11, 11 which then combined into a complete data operation means. Since the control unit 126 transmits the bit data of the sub data stream to all of the column electrodes D 1 to D N of the matrix display device 12, regardless of which position of the display surface 121 of the matrix display device 12 the operation device 11 operates, operation The device 11 can receive the bit data of the sub-data stream without missing.
以上之態樣是在電極與操作裝置11間建構一單一的傳送通道(single transmission channel),亦即單一發射源,在同一時間僅有一資料被傳送。另外亦可有多傳送通道的模式,如圖6C所示,在本實施例中,控制單元126可將資料流分流成複數子資料流ES1 ~ESK ,而該等子資料流ES1 ~ESK 分別具有複數個位元資料,每一子資料流(例如第一子資料流ES1 )有N個位元分別對應傳送至列電極D1 ~DN 。控制單元126負責將第一子資料流ES1 的第一位元傳遞至列電極D1 ,第二位元傳遞至列電極D2 ,最後將第一子資料流ES1 的第N位元傳遞至列電極DN ,再藉由這些列電極D1 ~DN 在一段時間內傳送至操作裝置11,然後再重複此資料遞送步驟。注意,資料除直接傳遞至電極外亦可將資料遞送至一緩衝器(buffer),然後在同一時間傳至電極上。在多傳送通道的模式下,除上述將各子資料流依序(第一子資料流ES1 傳送結束後再傳第二子資料流ES2 ,…,以此類推)傳至各電極外,與電極之間亦可有不同的搭配組合,例如將第一子資料流ES1 固定由列電極D1 傳送、第二子資料流ES2 固定由列電極D2 傳送等。於此,是以列電極D1 ~DN 代表所有列電極中之單一電極為例說明之,各D1 ~DN 亦可分別代表複數的列電極,或是各自代表由複數電極所組成之一電極群組(例如列電極D1 可表示為1、3、7電極之組合等,將在之後詳述),而這些電極均位在操作裝置11之可接收範圍內。The above aspect is to construct a single transmission channel between the electrode and the operating device 11, that is, a single transmission source, and only one data is transmitted at the same time. In addition, as shown in FIG. 6C, in the embodiment, the control unit 126 can split the data stream into the plurality of sub-data streams ES 1 to ES K , and the sub-data streams ES 1 ~ Each of the ES Ks has a plurality of bit data, and each of the sub-data streams (for example, the first sub-stream ES 1 ) has N bits correspondingly transmitted to the column electrodes D 1 to D N . The control unit 126 is responsible for transferring the first bit of the first sub-stream ES 1 to the column electrode D 1 , the second bit to the column electrode D 2 , and finally passing the N-th bit of the first sub-stream ES 1 The column electrode D N is further transferred to the operating device 11 by the column electrodes D 1 to D N for a period of time, and then the data delivery step is repeated. Note that the data can be delivered to a buffer in addition to being delivered directly to the electrode and then passed to the electrode at the same time. In the mode of the multi-transport channel, in addition to the above, each sub-data stream is sequentially transmitted (the first sub-stream stream ES 1 is transmitted, and then the second sub-stream stream ES 2 , ..., and so on) is transmitted to each electrode. There may be different combinations with the electrodes, for example, the first sub-stream ES 1 is fixed by the column electrode D 1 , the second sub-stream ES 2 is fixed by the column electrode D 2 , and the like. Here, the column electrodes D 1 to D N represent a single electrode of all the column electrodes as an example, and each of D 1 to D N may also represent a plurality of column electrodes, or each of them may be composed of a plurality of electrodes. an electrode group (e.g., column electrodes D 1 can be expressed as a combination of 1,3,7, like electrodes, will be described in detail later), and these electrodes are positioned within an acceptable range of operating device 11.
此外如前述,子資料流的位元數也可以依適當位元數目而被分流成複數的子資料流,並將該等列電極區分為複數群組,以分別將子資料流內的位元資料分別傳送至該等群組。例如可將資料流分流成小於列電極數目的子資料流,並將某一數目的列電極區分為同一群組,以分別將子資料流內的位元資料分別傳送至該等列電極的群組,藉此傳送至操作裝置11。In addition, as described above, the number of bits of the sub-stream can also be divided into a plurality of sub-data streams according to the number of appropriate bits, and the column electrodes are divided into a plurality of groups to respectively separate the bits in the sub-stream. The data is transmitted to these groups separately. For example, the data stream can be divided into sub-data streams smaller than the number of column electrodes, and a certain number of column electrodes are divided into the same group to respectively transmit the bit data in the sub-data stream to the group of the column electrodes respectively. The group is thereby transmitted to the operating device 11.
如圖6D所示,在本實施例中,每一子資料流ES1 ~ESK 係分別具有二個位元的資料(即第一位元及第二位元),而該等列電極D1 ~DN 之中,每4條列電極可組成一個群組(例如列電極D1 ~D4 為第一群組G1 ,列電極D5 ~D6 為第二群組G2 …,當然,也可不同數量的列電極組成一群組),且控制單元126於第一時間時將第一子資料流ES1 之第一位元,及於第二時間時將第二位元分別對應傳送至第一群組G1 之列電極D1 ~D4 及第二群組G2 之列電極D5 ~D8 ,並將第二子資料流ES2 (圖未顯示)之第一位元及第二位元於不同時間時分別對應傳送至第三群組G3 及第四群組G4 (圖未顯示),以此類推。As shown in FIG. 6D, in this embodiment, each of the sub-streams ES 1 to ES K has two bits of data (ie, the first bit and the second bit), and the column electrodes D Among the 1 to D N , each of the four column electrodes may be grouped into one group (for example, the column electrodes D 1 to D 4 are the first group G 1 and the column electrodes D 5 to D 6 are the second group G 2 ..., Of course, a different number of column electrodes may be grouped together, and the control unit 126 separates the first bit of the first sub-stream ES 1 at the first time and the second bit at the second time. corresponding to a first group G 1 is transmitted to the column electrodes D 1 ~ D 4 G 2 and the second group of the column electrodes D 5 ~ D 8, and the second sub-data stream ES 2 (not shown) of a first The bit and the second bit are respectively transmitted to the third group G 3 and the fourth group G 4 (not shown) at different times, and so on.
再者,為提高子資料流傳送至操作裝置11之正確性,可於不同的時間分別重覆傳送子資料流ES1 ~ESK 之位元資料至對應的第一群組G1 至第N/4群組GN/4 ,藉此可比對不同時間的傳送結果,以確保資料傳送的正確性。而操作裝置11可依傳送的規則將接收到的子資料流ES1 ~ESK 予以重新組合,以還原成資料。此外,上述的時間可為一個掃描時間內,或為一個圖框時間(frame time)內,或是相鄰兩個圖框時間之間。Furthermore, in order to improve the accuracy of the transmission of the sub-data stream to the operating device 11, the bit data of the sub-streams ES 1 to ES K can be repeatedly transferred to the corresponding first group G 1 to N at different times. /4 group G N/4 , which can be used to compare the transmission results at different times to ensure the correctness of data transmission. The operating device 11 can recombine the received sub-data streams ES 1 to ES K according to the transmitted rules to be restored into data. In addition, the above time may be within one scan time, or within a frame time, or between two adjacent frame times.
綜上所述,因本發明之資料傳輸系統包括一操作裝置及一矩陣顯示裝置,矩陣顯示裝置具有控制單元以接收資料流,而控制單元係將資料流之至少一部分傳送至一顯示面板之至少一電極,且當操作裝置在矩陣顯示裝置之顯示面上操作時,至少部分資料流係可從矩陣顯示裝置耦合至操作裝置。藉此,可使矩陣顯示裝置將資料或檔案等資料流藉由無線方式傳送至操作裝置。本發明之資料傳輸系統可與近距離無線通訊的應用結合,藉由顯示裝置將資料或檔案傳送至另一電子裝置,以擴大應用層面。In summary, the data transmission system of the present invention includes an operating device and a matrix display device, the matrix display device has a control unit to receive the data stream, and the control unit transmits at least a portion of the data stream to at least one of the display panels. An electrode, and when the operating device is operated on the display surface of the matrix display device, at least a portion of the data stream can be coupled from the matrix display device to the operating device. Thereby, the matrix display device can transmit the data stream such as data or files to the operating device by wireless means. The data transmission system of the present invention can be combined with the application of short-range wireless communication to transfer data or files to another electronic device by the display device to expand the application level.
