Description

顯示驅動器、顯示面板及資訊處理裝置Display driver, display panel and information processing device

本發明係關於一種顯示驅動器,特別是關於用以驅動具有GOA之顯示裝置的顯示驅動器。The present invention relates to a display driver, particularly to a display driver for driving a display device with GOA.

GOA(gate driver on array;板上閘極驅動電路)係集成在一顯示裝置之一基板上的驅動電路,一般會設有一行掃描電路和一源極通道開關電路,其中,該行掃描電路係用以依一工作時序驅動一TFT顯示面板的各行TFT(thin film transistor;薄膜電晶體)的閘極以導通各行TFT;及該源極通道開關電路係用以搭配該工作時序將源極資料經由各行導通的TFT傳送至該TFT顯示面板的各畫素單元。GOA (gate driver on array; on-board gate driver circuit) is a driver circuit integrated on a substrate of a display device. Generally, a row scanning circuit and a source channel switching circuit are provided. Among them, the row scanning circuit is Used to drive the gates of each row of TFTs (thin film transistors) of a TFT display panel according to a working sequence to turn on each row of TFTs; and the source channel switch circuit is used to match the working sequence to pass source data through The conductive TFTs of each row are transmitted to each pixel unit of the TFT display panel.

另外,一顯示驅動器會透過多條掃描控制信號線和集成在該基板上的GOA連接以驅動該TFT顯示面板,從而顯示一畫面。然而,當所述掃描控制信號線的數目很大時,該行掃描電路和該源極通道開關電路在該基板上的走線空間很可能會不足。In addition, a display driver is connected to the GOA integrated on the substrate through a plurality of scanning control signal lines to drive the TFT display panel to display a picture. However, when the number of the scan control signal lines is large, the wiring space of the row scan circuit and the source channel switch circuit on the substrate may be insufficient.

為解決上述問題,習知乃有在一顯示驅動器內設置一行掃描控制信號多工器及多個源極通道控制信號多工器,以減少輸出接腳的技術方案。請參照圖1,其為用以驅動一TFT顯示裝置20之一習知顯示驅動器10之一多工接腳方案的電路示意圖。如圖1所示,顯示驅動器10具有一第一多工器11及12個第二多工器12,且TFT顯示裝置20在一基板上形成有一行掃描電路21、一源極通道開關電路22及一TFT顯示結構23,其中,第一多工器11具有複數個第一輸入端、一第一控制埠及一個第一輸出端,所述複數個第一輸入端係用以與n個閘極掃描時鐘信號GCK 1-GCK n、一個幀啟始脈衝信號STV及一個發光啟始脈衝信號STE耦接,n為正整數,該第一控制埠係用以與至少一第一選擇信號SEL(1)耦接,所述第一輸出端係用以提供一第一輸出信號CGOUT,且第一多工器11係依所述至少一第一選擇信號SEL(1)的控制選擇所述複數個第一輸入端中的一輸入端以和該第一輸出端電氣連接;以及各第二多工器12均具有m個第二輸入端、一第二控制埠及一個第二輸出端,m為大於1的正整數,所述m個第二輸入端係用以與m個開關信號(例如SW 1-SW m)耦接,該第二控制埠係用以與至少一第二選擇信號SEL(j)耦接,j為介於2和13間之整數,所述第二輸出端係用以提供一第二輸出信號MUX(k),k為介於1和12間之整數,且各第二多工器12均係依所述至少一第二選擇信號SEL(j)的控制選擇所述複數個第二輸入端中的一輸入端以和該第二輸出端電氣連接。於操作時,TFT顯示裝置20內之行掃描電路21會對第一輸出信號CGOUT進行一第一解多工操作以逐行驅動TFT顯示結構23,且TFT顯示裝置20內之源極通道開關電路22會對第二輸出信號MUX(1)-MUX(12) 進行一第二解多工操作以依序開啟各畫素的源極資料通道,從而使TFT顯示裝置20的顯示幕呈現一畫面。 In order to solve the above-mentioned problems, there is a conventional technical solution in which a line scan control signal multiplexer and a plurality of source channel control signal multiplexers are arranged in a display driver to reduce output pins. Please refer to FIG. 1, which is a schematic circuit diagram of a multiplexed pin scheme of a conventional display driver 10 for driving a TFT display device 20. As shown in FIG. 1, the display driver 10 has a first multiplexer 11 and 12 second multiplexers 12, and the TFT display device 20 has a row scanning circuit 21 and a source channel switch circuit 22 formed on a substrate. And a TFT display structure 23, wherein the first multiplexer 11 has a plurality of first input terminals, a first control port, and a first output terminal, and the plurality of first input terminals are used to interact with n gates Polar scanning clock signals GCK 1 -GCK n , a frame start pulse signal STV and a light start pulse signal STE are coupled, n is a positive integer, and the first control port is used to interact with at least one first selection signal SEL( 1) Coupled, the first output terminal is used to provide a first output signal CGOUT, and the first multiplexer 11 is controlled by the at least one first selection signal SEL(1) to select the plurality of One of the first input terminals is electrically connected to the first output terminal; and each second multiplexer 12 has m second input terminals, a second control port, and a second output terminal, where m is A positive integer greater than 1, the m second input terminals are used to couple to m switch signals (eg SW 1 -SW m ), and the second control port is used to communicate with at least one second selection signal SEL( j) coupling, j is an integer between 2 and 13, the second output terminal is used to provide a second output signal MUX(k), k is an integer between 1 and 12, and each The two multiplexers 12 both select one of the plurality of second input terminals to be electrically connected to the second output terminal under the control of the at least one second selection signal SEL(j). During operation, the row scanning circuit 21 in the TFT display device 20 performs a first demultiplexing operation on the first output signal CGOUT to drive the TFT display structure 23 row by row, and the source channel switch circuit in the TFT display device 20 22 performs a second demultiplexing operation on the second output signals MUX(1)-MUX(12) to sequentially turn on the source data channels of each pixel, so that the display screen of the TFT display device 20 presents a picture.

然而,當顯示幕需高解析度時,顯示驅動器10的第二輸出信號MUX(k)的數目會變多,而如果此時基板的面積須被限制在一小範圍(例如智慧型手錶的顯示幕)內,則連接至行掃描電路21的第一輸出信號CGOUT極可能和連接至源極通道開關電路22的第二輸出信號MUX(k)產生交叉,從而使該基板上的信號走線無法完成。However, when the display screen requires high resolution, the number of second output signals MUX(k) of the display driver 10 will increase, and if the area of the substrate must be limited to a small range (such as the display of a smart watch) In the screen), the first output signal CGOUT connected to the row scanning circuit 21 is very likely to cross the second output signal MUX(k) connected to the source channel switch circuit 22, so that the signal routing on the substrate cannot carry out.

為解決上述問題,本領域亟需一新穎的顯示幕掃描驅動方法。In order to solve the above problems, a novel scanning driving method of the display screen is urgently needed in the art.

Circuit or source channel control circuit.

請參照圖2,其為本發明用以驅動一TFT顯示裝置200之一顯示驅動器100之一多工接腳實施例的電路示意圖。如圖2所示,顯示驅動器100具有一多工器110,且TFT顯示裝置200在一基板上形成有一行掃描電路210、一源極通道開關電路220及一TFT顯示結構230,其中,多工器110具有複數個輸入端、一控制埠及至少一個輸出端,所述複數個輸入端係用以與n個閘極掃描時鐘信號GCK 1-GCK n、一個幀啟始脈衝信號STV、一個發光啟始脈衝信號STE及L個開關信號SW 1-SW L耦接,n、L皆為正整數,該控制埠係用以與至少一選擇信號SEL耦接,所述至少一個輸出端係用以提供至少一輸出信號VSR並和該基板上之複數條走線連接,所述複數條走線係和行掃描電路210或源極通道開關電路220連接,且多工器110係依所述至少一選擇信號SEL的控制選擇所述複數個輸入端中的一輸入端以和該輸出端電氣連接。 Please refer to FIG. 2, which is a schematic circuit diagram of a multiplexed pin embodiment of a display driver 100 for driving a TFT display device 200 of the present invention. As shown in FIG. 2, the display driver 100 has a multiplexer 110, and the TFT display device 200 has a row scanning circuit 210, a source channel switch circuit 220, and a TFT display structure 230 formed on a substrate. The device 110 has a plurality of input terminals, a control port and at least one output terminal, and the plurality of input terminals are used to communicate with n gate scan clock signals GCK 1 -GCK n , a frame start pulse signal STV, and a light emitting The start pulse signal STE and the L switch signals SW 1 -SW L are coupled, n and L are both positive integers, the control port is used for coupling with at least one selection signal SEL, and the at least one output terminal is used for At least one output signal VSR is provided and connected to a plurality of traces on the substrate. The plurality of traces are connected to the row scanning circuit 210 or the source channel switch circuit 220, and the multiplexer 110 is based on the at least one The control of the selection signal SEL selects an input terminal of the plurality of input terminals to be electrically connected to the output terminal.

於操作時,TFT顯示裝置200內之行掃描電路210可藉由對至少一輸出信號VSR進行一第一解多工操作以逐行驅動TFT顯示結構230,且TFT顯示裝置200內之源極通道開關電路220亦可藉由對至少一輸出信號VSR進行一第二解多工操作以依序開啟各畫素的源極資料通道,從而使TFT顯示裝置200的顯示幕呈現一畫面。During operation, the row scanning circuit 210 in the TFT display device 200 can drive the TFT display structure 230 row by row by performing a first demultiplexing operation on at least one output signal VSR, and the source channel in the TFT display device 200 The switch circuit 220 can also perform a second demultiplexing operation on the at least one output signal VSR to sequentially turn on the source data channels of each pixel, so that the display screen of the TFT display device 200 presents a picture.

In addition, the number of output signals VSR can be adjusted according to the data transmission bandwidth requirements of the display: when the display requires a larger data transmission bandwidth, more output signals VSR can be set; and when the display does not require a large When data transmission bandwidth, less output signal VSR can be set.
