Description

時序控制器、驅動器、驅動單元、顯示器及資料傳輸方法Timing controller, driver, drive unit, display, and data transmission method

本發明是有關於一種時序控制器、驅動器、驅動單元、顯示器及資料傳輸方法，且特別是有關於一種使用低擺幅差動訊號資料之形式來傳輸指令訊號之時序控制器、驅動器、驅動單元、顯示器及資料傳輸方法。The invention relates to a timing controller, a driver, a driving unit, a display and a data transmission method, and particularly relates to a timing controller, a driver and a driving unit for transmitting an instruction signal in the form of low swing differential signal data. , display and data transmission methods.

請參照第1圖，其繪示乃傳統顯示器之示意圖，顯示器10包括面板11、時序控制器13及多個資料驅動器141~14n。在傳統的資料傳輸結構中，時序控制器13與資料驅動器141~14n之間的傳輸訊號形式可分為電晶體邏輯(Transistor－transistor Logic，TTL)訊號與低擺幅差動訊號(Reduced Swing Differential Signal，RSDS)兩類。其中，於第1圖中，係以複數對訊號線之形式來表達所傳輸訊號之形式為低擺幅差動訊號，與單條訊號線所表達之電晶體邏輯訊號做區隔。Please refer to FIG. 1 , which is a schematic diagram of a conventional display. The display 10 includes a panel 11 , a timing controller 13 and a plurality of data drivers 141 14 14 n . In the conventional data transmission structure, the transmission signal form between the timing controller 13 and the data drivers 141~14n can be divided into a Transistor-Transistor Logic (TTL) signal and a Low Swing Differential signal (Reduced Swing Differential). Signal, RSDS) two categories. In the first figure, the form of the transmitted signal is expressed in the form of a plurality of signal lines as a low-swing differential signal, which is distinguished from the transistor logic signal expressed by a single signal line.

其中，時脈訊號RSDS_CLK以及與畫素相關聯之資料訊號，例如紅光資料訊號Data_R、綠光資料訊號Data_G及藍光資料訊號Data_B，是以低擺幅差動訊號的形式由時序控制器13經複數對訊號線傳送至資料驅動器141~14n，依顯示器所能顯示的色彩多寡而定，前述紅光、綠光、藍光資料可能各需要三對或三對以上的訊號線傳送資料。而時序控制器13中用以控制資料驅動器141~14n之控制訊號，例如由時序控制器13傳送至資料驅動器141~14n的時序控制訊號TP1、電壓極性控制訊號POL、由時序控制器13傳至資料驅動器141的起始控制訊號STH以及資料驅動器141~14n間之致能訊號Enb_X(X＝1~n－1)則是以電晶體邏輯訊號之形式進行傳遞。The clock signal RSDS_CLK and the data signal associated with the pixel, such as the red data signal Data_R, the green data signal Data_G, and the blue light data signal Data_B, are in the form of low swing differential signals by the timing controller 13 The plurality of signal lines are transmitted to the data drivers 141~14n, and the red, green, and blue light data may each need three or more pairs of signal lines to transmit data according to the amount of color that the display can display. The control signals of the timing controller 13 for controlling the data drivers 141~14n are transmitted to the data drivers 141~14n by the timing controller 13, for example. The timing control signal TP1, the voltage polarity control signal POL, the start control signal STH transmitted from the timing controller 13 to the data driver 141, and the enable signal Enb_X (X=1~n-1) between the data drivers 141~14n are Transfer in the form of a transistor logic signal.

當資料驅動器141接收到起始控制訊號STH後，資料驅動器141開始接收從時序控制器13傳送而來的資料訊號Data_R、Data_G及Data_B。當資料區動器141完成資料的接收之後，資料驅動器141發出致能訊號Enb_1至資料驅動器142，以使資料驅動器142開始接收從時序控制器13傳送而來得資料訊號Data_R、Data_G及Data_B。而當資料驅動器142完成資料的接收之後，資料驅動器142發出致能訊號Enb_2至資料驅動器143。其餘的資料驅動器143~14n的操作方式亦同，於此不予贅述。When the data driver 141 receives the start control signal STH, the data driver 141 starts receiving the data signals Data_R, Data_G, and Data_B transmitted from the timing controller 13. After the data zone 141 completes the reception of the data, the data driver 141 issues the enable signal Enb_1 to the data driver 142 to cause the data driver 142 to start receiving the data signals Data_R, Data_G and Data_B transmitted from the timing controller 13. When the data driver 142 completes the reception of the data, the data driver 142 issues the enable signal Enb_2 to the data driver 143. The operation modes of the remaining data drivers 143~14n are also the same, and will not be described here.

然而，為了得以正確地對控制訊號進行判斷，電晶體邏輯訊號於時脈訊號上升緣(rising edge)或下降緣(falling edge)產生前必須具有足夠之建立時間(setup time)，且於時脈訊號上升緣或下降緣產生後必須維持足夠之保持時間(hold time)。如此，當系統運作速度加快時，電晶體邏輯訊號之建立時間及保持時間將會過短，不足以配合系統運作速度，故容易讀取到不正確的控制訊號，致使顯示器10顯示不正確的畫面。However, in order to correctly judge the control signal, the transistor logic signal must have sufficient setup time and clock before the rising edge or falling edge of the clock signal is generated. A sufficient hold time must be maintained after the rising or falling edge of the signal is generated. In this way, when the system operates faster, the setup time and hold time of the transistor logic signal will be too short to match the system operation speed, so it is easy to read the incorrect control signal, causing the display 10 to display an incorrect picture. .

除此之外，資料驅動器141~14n間之致能訊號Enb_X亦為電晶體邏輯訊號，於高頻時在傳遞上易產生失真或延遲。甚且，基於致能訊號Enb_X係於資料驅動器完成接收資料之後，才發送給下一個資料驅動器。故資料驅動器所需之處理時間亦會讓致能訊號Enb_X有延遲產生。如此一來將會導致資料驅動器141~14n無法於正確的時間被致能以讀取資料驅動器141~14n所應讀取之資料訊號，而讀取到錯誤之資料訊號，進而使得顯示器10顯示不正確之畫面。In addition, the enable signal Enb_X between the data drivers 141~14n is also a transistor logic signal, which is prone to distortion or delay in transmission at high frequencies. Moreover, the enabling signal Enb_X is sent to the next data driver after the data driver completes receiving the data. Therefore, the processing time required by the data driver will also cause delay in the enable signal Enb_X. Such a The data drivers 141~14n cannot be enabled at the correct time to read the data signals to be read by the data drivers 141~14n, and the wrong data signals are read, so that the display 10 is displayed incorrectly. Picture.

本發明提出一種時序控制器、驅動器、驅動單元、顯示器及資料傳輸方法，時序控制器藉由使用低擺幅差動訊號之形式來傳輸指令訊號，使得系統在高頻操作時，每個驅動器所接收到之控制訊號與時序控制器所送出之資料訊號能夠同步，以使驅動器可以讀取正確之資料訊號，顯示器能顯示正確之畫面。The invention provides a timing controller, a driver, a driving unit, a display and a data transmission method.

請參照第3圖，其繪示乃依照本發明之較佳實施例之顯示器之示意圖。顯示器30包括面板31以及驅動單元32，驅動單元32包括時序控制器33以及多個驅動器，驅動器例如為資料驅動器341~34n。於本實施例中，此多個驅動器係以資料驅動器為例做說明，但其他類型驅動器，如掃描驅動器，亦可應用於本實施例中。此外，於第3圖中，係以複數對訊號線之形式來表達所傳輸訊號之形式為低擺幅差動訊號，與單條訊號線所表達之電晶體邏輯訊號做區隔。Please refer to FIG. 3, which is a schematic diagram of a display according to a preferred embodiment of the present invention. The display 30 includes a panel 31 and a driving unit 32. The driving unit 32 includes a timing controller 33 and a plurality of drivers, such as data drivers 341 to 34n. In this embodiment, the plurality of drivers are described by taking a data driver as an example, but other types of drivers, such as a scan driver, can also be applied in this embodiment. In addition, in FIG. 3, the form of the transmitted signal is expressed in the form of a plurality of signal lines as a low-swing differential signal, which is distinguished from the transistor logic signal expressed by a single signal line.

時序控制器33係用以經由複數對訊號線送出低擺幅差動時脈訊號RSDS_CLK和資料訊號，包括紅光資料訊號Data_R、綠光資料訊號Data_G及藍光資料訊號Data_B，至資料驅動器341~34n。時序控制器33更用以經由一對訊號線送出低擺幅差動指令訊號RSDS_CMD，至資料驅動器341~34n。包含不同的控制碼的低擺幅差動指令訊號RSDS_CMD係用以代表不同的控制訊號，例如用以代表起始控制訊號STH、時序控制訊號TP1或電壓極性控制訊號POL。The timing controller 33 is configured to send the low swing differential clock signal RSDS_CLK and the data signal through the plurality of signal lines, including the red data signal Data_R, the green data signal Data_G and the blue data signal Data_B, to the data drivers 341~34n . The timing controller 33 is further configured to send the low swing differential command signal RSDS_CMD to the data drivers 341~34n via a pair of signal lines. The low swing differential command signal RSDS_CMD including different control codes is used to represent different control signals, for example, to represent the initial control signal STH, the timing control signal TP1 or the voltage polarity control signal POL.

其中，起始控制訊號STH係用以指示資料驅動器341~34n開始接收從時序控制器33傳送而來的資料訊號Data_R、Data_G及Data_B。而當時序控制訊號TP1為致能時，資料驅動器341~34n將對應至所接收的資料訊號Data_R、Data_G及Data_B的畫素電壓輸出至面板31，電壓極性控制訊號POL係用以決定對應至所接收之資料訊號之畫素電壓的極性。The initial control signal STH is used to instruct the data drivers 341 to 34n to start receiving the data signals Data_R, Data_G, and Data_B transmitted from the timing controller 33. When the timing control signal TP1 is enabled, the data drivers 341~34n output the pixel voltages corresponding to the received data signals Data_R, Data_G, and Data_B to the panel 31, and the voltage polarity control signal POL is used to determine the corresponding location. The polarity of the pixel voltage of the received data signal.

請參照表1，其所繪示乃當n＝3時，上述之用以代表起始控制訊號STH、時序控制訊號TP1及電壓極性控制訊號POL之低擺幅差動指令訊號RSDS_CMD的指令內容值之一例。本實施例係根據所要輸出之控制訊號，根據表1產生12位元(bit)之指令，然後以數位傳輸之形式，串列式地將低擺幅差動指令訊號RSDS_CMD輸出至所有的資料驅動器341~34n。其中，不同的控制訊號之狀態(高位準或低位準之狀態)係可由不同的控制碼來區別之。Please refer to Table 1, which is shown as the command content value of the low swing differential command signal RSDS_CMD for the initial control signal STH, the timing control signal TP1 and the voltage polarity control signal POL when n=3. One example. In this embodiment, according to the control signal to be output, a 12-bit instruction is generated according to Table 1, and then the low-swing differential command signal RSDS_CMD is serially outputted to all data drivers in the form of digital transmission. 341~34n. Among them, the state of the different control signals (the state of the high level or the low level) can be distinguished by different control codes.

此外，差動資料訊號之調整方式亦可同時應用於低擺幅差動訊號指令對。偏斜控制之調整方式係於時序控制器33上之三個偏斜控制腳位(pin)輸入偏斜控制值，以調整低擺幅差動資料訊號及低擺幅差動指令訊號之建立時間及保持時間。偏斜控制值及所對應之建立時間及保持時間的關係請參照表2，其中T代表低擺幅差動資料訊號及低擺幅差動指令訊號之訊號週期，而此建立時間及保持時間例如是參考時序控制器33之系統時脈訊號計算得之。In addition, the adjustment method of the differential data signal can also be applied to the low swing differential signal command pair. The adjustment method of the skew control is based on the three skew control pin (pin) input skew control values on the timing controller 33 to adjust the settling time of the low swing differential data signal and the low swing differential command signal. And hold time. For the relationship between the skew control value and the corresponding setup time and hold time, refer to Table 2, where T represents the signal period of the low swing differential data signal and the low swing differential command signal, and the setup time and hold time are, for example. It is calculated by referring to the system clock signal of the timing controller 33.

由於對應至所有資料驅動器341~34n的起始控制訊號STH的低擺幅差動指令訊號RSDS_CMD皆是由時序控制器33所產生，時序控制器33可以根據所要輸出之資料訊號，於正確的時間點依序輸出每個資料驅動器之起始控制訊號STH所對應的低擺幅差動指令訊號RSDS_CMD。因此，本實施例解決了傳統作法中，由資料驅動器輸出起始控制訊號以控制下一個資料驅動器，而造成起始控制訊號傳遞延遲，而使得資料驅動器讀取到錯誤之資料訊號，進而使得顯示器顯示不正確之畫面之問題。Since the low swing differential command signal RSDS_CMD corresponding to the start control signal STH of all the data drivers 341~34n is generated by the timing controller 33, the timing controller 33 can be based on the data signal to be output at the correct time.
