主動式矩陣顯示面板與其驅動方法 Active matrix display panel and driving method thereof

本發明是有關於一種主動式矩陣顯示面板與其驅動方法,且特別是有關於一種可應用於雙邊掃描驅動器,且可降低掃描驅動器的掃描通道的數目之主動式矩陣顯示面板與其驅動方法。 The present invention relates to an active matrix display panel and a driving method thereof, and more particularly to an active matrix display panel and a driving method thereof that can be applied to a bilateral scanning driver and can reduce the number of scanning channels of the scanning driver.

第1A圖繪示傳統液晶顯示器100之方塊圖。傳統液晶顯示器100包括一掃描驅動器110、一資料驅動器120、數條掃描線、數條資料線與一液晶顯示面板130。液晶顯示面板130包括數個畫素單元。 FIG. 1A is a block diagram of a conventional liquid crystal display 100. The conventional liquid crystal display 100 includes a scan driver 110, a data driver 120, a plurality of scan lines, a plurality of data lines, and a liquid crystal display panel 130. The liquid crystal display panel 130 includes a plurality of pixel units.

當液晶顯示面板130朝大尺寸發展時,液晶顯示器100的掃描線的長度會增加。由於掃描線上的電阻電容效應(RC effect),當致能一掃描線的掃描訊號時,掃描線上遠離掃描驅動器的位置上實際得到的掃描訊號的波形係會失真。 When the liquid crystal display panel 130 is developed toward a large size, the length of the scanning line of the liquid crystal display 100 may increase. Due to the RC effect on the scan line, when the scan signal of a scan line is enabled, the waveform of the actually obtained scan signal at the position on the scan line away from the scan driver is distorted.

茲以掃描線111上的A點與B點的掃描訊號的波形為例,說明上述波形失真的情形。第1B圖繪示在掃描線111的A點上的掃描訊號的波形圖之一例。第1C圖繪示在掃描線111的B點上的掃描訊號的波形圖之一例。其中,B點係較A點遠離掃描驅動器110。當A點上的掃描訊號為致能時,亦即A點上的掃描訊號為高位準時,畫素單元131內的開關係被A點上的掃描訊號導通,畫素單元131即接 收資料驅動器120透過資料線傳送而來的畫素資料。同樣地,當B點上的掃描訊號為致能時,畫素單元132內的開關係被導通,畫素單元132即接收畫素資料。 The waveform distortion of the above-mentioned waveforms will be described by taking the waveform of the scanning signals of points A and B on the scanning line 111 as an example. FIG. 1B is a diagram showing an example of a waveform diagram of a scanning signal at point A of the scanning line 111. FIG. 1C is a diagram showing an example of a waveform diagram of a scanning signal at point B of the scanning line 111. Among them, point B is farther away from scan driver 110 than point A. When the scanning signal at point A is enabled, that is, when the scanning signal at point A is high, the open relationship in the pixel unit 131 is turned on by the scanning signal at point A, and the pixel unit 131 is connected. The pixel data transmitted from the data driver 120 through the data line is received. Similarly, when the scan signal at point B is enabled, the open relationship in the pixel unit 132 is turned on, and the pixel unit 132 receives the pixel data.

在第1B圖中,在一掃描時段T0內,掃描驅動器110致能掃描線111上的掃描訊號。由於A點較靠近掃描驅動器110,其所受的電阻電容效應較低,故A點上的掃描訊號在掃描時段T0內係為高位準。亦即,A點上的掃描訊號未失真。 In FIG. 1B, the scan driver 110 enables the scan signal on the scan line 111 during a scan period T0. Since the point A is closer to the scan driver 110, the resistance-capacitance effect is lower, so the scan signal at point A is at a high level during the scan period T0. That is, the scan signal at point A is not distorted.

而在第1C圖中,由於B點較遠離掃描驅動器110,其所受的RC效應較高,故B點上的掃描訊號在掃描時段T0內係慢慢由低位準轉為高位準。在掃描時段T0後,B點上的掃描訊號再慢慢回復至低位準。 In FIG. 1C, since the point B is farther away from the scan driver 110, the RC effect is higher, so the scan signal at the point B is slowly changed from the low level to the high level during the scanning period T0. After the scanning period T0, the scanning signal at point B slowly returns to the low level.

因此,在掃描時段T0內,B點上的掃描訊號維持高位準的時間係較A點上的掃描訊號維持高位準的時間短。因此,在掃描時段T0內,畫素單元132內的開關導通的時間係較畫素單元131內的開關導通的時間短。因此,畫素單元132內的儲存電容充電的時間較短,無法在掃描時段T0內充電到預定位準。故畫素單元132的亮度會低於畫素單元131的亮度。 Therefore, during the scanning period T0, the time at which the scanning signal at point B is maintained at a high level is shorter than the time at which the scanning signal at point A is maintained at a high level. Therefore, during the scanning period T0, the time during which the switch in the pixel unit 132 is turned on is shorter than the time during which the switch in the pixel unit 131 is turned on. Therefore, the storage capacitor in the pixel unit 132 is charged for a short time and cannot be charged to a predetermined level during the scanning period T0. Therefore, the luminance of the pixel unit 132 is lower than the luminance of the pixel unit 131.

因此,當液晶顯示面板130朝大尺寸發展時,遠離掃描驅動器110的畫面會較暗,產生畫面亮度不均的問題。故傳統架構無法適用於大尺寸的液晶顯示器。 Therefore, when the liquid crystal display panel 130 is developed toward a large size, the screen away from the scan driver 110 may be dark, causing a problem of uneven brightness of the screen. Therefore, the conventional architecture cannot be applied to a large-sized liquid crystal display.

第2圖繪示另一傳統液晶顯示器之方塊圖。與第1A圖的液晶顯示器相較之下,液晶顯示器200係於液晶顯示 面板130的兩側設置一第一側掃描驅動器140與一第二側掃描驅動器150。第一側掃描驅動器140與第二側掃描驅動器150送出時序相同的掃描訊號。如此,在第2圖中,遠離掃描驅動器140的B點係較靠近掃描驅動器150。故B點上的掃描訊號不會因為RC效應而失真。如此,即可改善第1A圖之掃描線上,遠離掃描驅動器110的位置的掃描訊號失真的問題。進而使得液晶顯示面板130的畫面亮度均勻。 FIG. 2 is a block diagram of another conventional liquid crystal display. Compared with the liquid crystal display of FIG. 1A, the liquid crystal display 200 is connected to the liquid crystal display. A first side scan driver 140 and a second side scan driver 150 are disposed on both sides of the panel 130. The first side scan driver 140 and the second side scan driver 150 send the same scan signal at the same timing. As such, in FIG. 2, point B away from scan driver 140 is closer to scan driver 150. Therefore, the scanning signal at point B is not distorted by the RC effect. In this way, the problem of distortion of the scanning signal at the position on the scanning line of FIG. 1A away from the scanning driver 110 can be improved. Further, the screen brightness of the liquid crystal display panel 130 is made uniform.

然而,液晶顯示器200相較液晶顯示器100多了一個掃描驅動器。液晶顯示器200的掃描通道(Scan channel)的數量係為第1A圖的液晶顯示器的掃描通道的數量的兩倍。因此,液晶顯示器200的生產成本較高,且使用時更加耗電。 However, the liquid crystal display 200 has one more scan driver than the liquid crystal display 100. The number of scanning channels of the liquid crystal display 200 is twice the number of scanning channels of the liquid crystal display of FIG. 1A. Therefore, the liquid crystal display 200 is more expensive to produce and consumes more power when used.

主動式矩陣顯示面板500的每個畫素單元受控於掃描線L1至L6其中之一。當畫素單元被掃描線致能時,接收由對應的資料線所傳送而來之畫素資料。其中,畫素資料係由資料驅動器630所輸出。 Each pixel unit of the active matrix display panel 500 is controlled by one of the scan lines L1 to L6. When the pixel unit is enabled by the scan line, the pixel data transmitted by the corresponding data line is received. The pixel data is output by the data driver 630.

茲說明第5圖之主動式矩陣顯示面板之動作。第6圖繪示第5圖之掃描訊號SC1至SC6、控制訊號P1至P4、掃描線L1至L4上之訊號的時序圖之一例。在本實施例中,上述各訊號在被致能時係為高位準,在被非致能時係為低位準。高位準係為可以導通各開關的位準,低位準係 為可以關閉各開關的位準。 The operation of the active matrix display panel of Fig. 5 will be explained. FIG. 6 is a diagram showing an example of a timing chart of the signals on the scanning signals SC1 to SC6, the control signals P1 to P4, and the scanning lines L1 to L4 in FIG. In this embodiment, each of the above signals is a high level when enabled, and a low level when disabled. High level is the level that can turn on each switch, low level In order to close the level of each switch.

請同時參考第5圖與第6圖。在掃描時段T1內,掃描訊號SC1與SC2、控制訊號P1與P4係被致能;掃描訊號SC3至SC7、控制訊號P2與P3係被非致能。 Please also refer to Figures 5 and 6. During the scanning period T1, the scanning signals SC1 and SC2, the control signals P1 and P4 are enabled; the scanning signals SC3 to SC7, and the control signals P2 and P3 are disabled.

被致能之掃描線SC2導通開關SW1,使得控制訊號P1係透過開關SW1傳送至掃描線L1之一端。由於控制訊號P1為致能,故使得掃描線L1被致能。另外,掃描訊號SC1為致能,掃描訊號SC1由掃描線L1之另一端致能掃描線。故在掃描時段T1內,掃描線L1的兩端分別接收致能之控制訊號P1與致能之掃描訊號SC1而被致能。 The enabled scan line SC2 turns on the switch SW1, so that the control signal P1 is transmitted to one end of the scan line L1 through the switch SW1. Since the control signal P1 is enabled, the scan line L1 is enabled. In addition, the scan signal SC1 is enabled, and the scan signal SC1 is enabled by the other end of the scan line L1. Therefore, in the scan period T1, both ends of the scan line L1 are respectively enabled to receive the enable control signal P1 and the enable scan signal SC1.

在掃描時段T1內,控制訊號P2為非致能,且掃描訊號SC3為非致能,故開關SW2與SW3為關閉。如此,沒有訊號可以透過開關SW2與SW3傳送至掃描線L2。故掃描線L2係為浮接狀態(Floating)。若掃描線進入浮接狀態前為非致能,則進入浮接狀態後係會維持非致能。反之,則掃描線維持致能。在本實施例中,由於掃描線L2在初始時為非致能,故掃描線L2在掃描時段T1內係會保持為非致能。同理,掃描線L4亦進入浮接狀態,並保持為非致能。 During the scanning period T1, the control signal P2 is disabled, and the scanning signal SC3 is disabled, so the switches SW2 and SW3 are off. Thus, no signal can be transmitted to the scan line L2 through the switches SW2 and SW3. Therefore, the scanning line L2 is in a floating state. If the scan line is not enabled before it enters the floating state, it will remain disabled after entering the floating state. Otherwise, the scan line remains enabled. In the present embodiment, since the scan line L2 is initially disabled, the scan line L2 remains non-enabled during the scan period T1. Similarly, the scan line L4 also enters the floating state and remains disabled.

在掃描時段T1內,掃描訊號SC4為非致能,故開關SW4為關閉,而控制訊號P4為致能,故開關SW5導通。因此,掃描訊號SC3係透過開關SW5被傳送至掃描線L3。由於掃描訊號SC3係為非致能,故在掃描時段T1內,掃描線L3係被非致能。同理,掃描線L5係被非致能。 During the scanning period T1, the scanning signal SC4 is disabled, so the switch SW4 is turned off, and the control signal P4 is enabled, so the switch SW5 is turned on. Therefore, the scanning signal SC3 is transmitted to the scanning line L3 through the switch SW5. Since the scan signal SC3 is disabled, the scan line L3 is disabled during the scan period T1. Similarly, the scan line L5 is disabled.

另外,掃描線L6之一端接收非致能之掃描訊號SC7,故掃描線L6亦被非致能。 In addition, one end of the scanning line L6 receives the non-enabled scanning signal SC7, so the scanning line L6 is also disabled.

因此,在掃描時段T1內,掃描線L1係被致能,掃描線L2至L6係被非致能。掃描線L1致能其所對應的畫素單元,使得每個被致能的畫素單元接收由對應的資料線所傳送而來之畫素資料。 Therefore, in the scanning period T1, the scanning line L1 is enabled, and the scanning lines L2 to L6 are disabled. The scan line L1 enables its corresponding pixel unit such that each enabled pixel unit receives the pixel data transmitted by the corresponding data line.

接著,在掃描時段T2內,掃描訊號SC2與SC3、控制訊號P2與P3係被致能,而掃描訊號SC1、SC4至SC7、控制訊號P1與P4係被非致能。 Then, during the scanning period T2, the scanning signals SC2 and SC3, the control signals P2 and P3 are enabled, and the scanning signals SC1, SC4 to SC7, and the control signals P1 and P4 are disabled.

被致能之掃描訊號SC2導通開關SW1,使得控制訊號P1透過開關SW1傳送至掃描線L1。由於此時控制訊號P1為非致能,故掃描線L1係被非致能。另外,掃描訊號SC1係被非致能,掃描訊號SC1由掃描線L1之另一端輸入至掃描線L1,亦使得掃描線L1被非致能。 The enabled scan signal SC2 turns on the switch SW1, so that the control signal P1 is transmitted to the scan line L1 through the switch SW1. Since the control signal P1 is disabled at this time, the scan line L1 is disabled. In addition, the scan signal SC1 is disabled, and the scan signal SC1 is input to the scan line L1 from the other end of the scan line L1, so that the scan line L1 is disabled.

被致能之控制訊號P2導通開關SW2,而被致能之掃描訊號SC3導通開關SW3。故掃描訊號SC2透過開關SW2傳送至掃描線L2之一端,控制訊號P3透過開關SW3傳送至掃描線L2之另一端。因此,於掃描時段T2,掃描線L2的兩端分別接收被致能之掃描訊號SC2與被致能之控制訊號P3。掃描線即L2被致能。 The enabled control signal P2 turns on the switch SW2, and the enabled scan signal SC3 turns on the switch SW3. Therefore, the scanning signal SC2 is transmitted to one end of the scanning line L2 through the switch SW2, and the control signal P3 is transmitted to the other end of the scanning line L2 through the switch SW3. Therefore, at the scanning period T2, both ends of the scanning line L2 receive the enabled scanning signal SC2 and the enabled control signal P3. The scan line, L2, is enabled.

被非致能之掃描訊號SC4關閉開關SW4,而被非致能之控制訊號P4關閉開關SW5。故掃描線L3進入浮接狀態。由於掃描線L3在進入浮接狀態前係為非致能,故掃描線L3在浮接狀態時即保持為非致能。 The non-enabled scan signal SC4 turns off the switch SW4, and the non-enabled control signal P4 turns off the switch SW5. Therefore, the scanning line L3 enters the floating state. Since the scan line L3 is disabled before entering the floating state, the scan line L3 remains non-enabled in the floating state.

類似在掃描時段T1內掃描線L2的動作,在掃描時段T2內,掃描線L4係被非致能。類似在掃描時段T2內掃描線L3,在掃描時段T2內,掃描線L5進入浮接狀態,並保持為非致能。類似在掃描時段T1內掃描線L6的動作,在掃描時段T2內,掃描線L6係被非致能。 Similar to the action of scanning the line L2 during the scanning period T1, the scanning line L4 is disabled in the scanning period T2. Similarly to the scanning line L3 in the scanning period T2, in the scanning period T2, the scanning line L5 enters the floating state and remains disabled. Similar to the action of the scanning line L6 in the scanning period T1, the scanning line L6 is disabled in the scanning period T2.

因此,在掃描時段T2內,掃描線L2係被致能,掃描線L1、L3至L6係被非致能。掃描線L2致能其所對應的畫素單元,使得每個被致能的畫素單元接收由對應的資料線所傳送而來之畫素資料。 Therefore, in the scanning period T2, the scanning line L2 is enabled, and the scanning lines L1, L3 to L6 are disabled. The scan line L2 enables its corresponding pixel unit such that each enabled pixel unit receives the pixel data transmitted by the corresponding data line.

接著,在掃描時段T3內,掃描訊號SC3與SC4、控制訊號P1與P4係被致能,掃描訊號SC1、SC2、SC5至SC7、控制訊號P2與P3係被非致能。被致能之掃描訊號SC4導通開關SW4,而被致能之控制訊號P4導通開關SW5。故控制訊號P1透過開關SW4傳送至掃描線L3之一端,而掃描訊號SC3透過開關SW5傳送至掃描線L3之另一端。由於控制訊號P1與掃描訊號SC3係均為致能,故於掃描時段T3內,掃描線L3的兩端分別接收被致能之控制訊號P1與掃描訊號SC3而被致能。 Then, during the scanning period T3, the scanning signals SC3 and SC4, the control signals P1 and P4 are enabled, and the scanning signals SC1, SC2, SC5 to SC7, and the control signals P2 and P3 are disabled. The enabled scan signal SC4 turns on the switch SW4, and the enabled control signal P4 turns on the switch SW5. Therefore, the control signal P1 is transmitted to one end of the scanning line L3 through the switch SW4, and the scanning signal SC3 is transmitted to the other end of the scanning line L3 through the switch SW5. Since both the control signal P1 and the scan signal SC3 are enabled, in the scan period T3, both ends of the scan line L3 are respectively enabled to be enabled by the control signal P1 and the scan signal SC3.

類似掃描時段T2內掃描線L3的動作,於掃描時段T3內,掃描線L4係進入浮接狀態。由於掃描線L4在進入浮接狀態前,亦即在掃描時段T2內,被非致能,故於掃描時段T3內掃描線L4仍保持非致能。類似掃描時段T1內掃描線L5與L6的動作,掃描線L5與L6於掃描時段T3內係被非致能。 Similar to the action of the scanning line L3 in the scanning period T2, the scanning line L4 enters the floating state during the scanning period T3. Since the scan line L4 is disabled before entering the floating state, that is, during the scan period T2, the scan line L4 remains non-enabled during the scan period T3. Similar to the action of the scanning lines L5 and L6 in the scanning period T1, the scanning lines L5 and L6 are disabled in the scanning period T3.

因此,在掃描時段T3內,掃描線L3係被致能,掃描線L1、L2、L4至L6係被非致能。掃描線L3致能其所對應的畫素單元,使得每個被致能的畫素單元接收由對應的資料線所傳送而來之畫素資料。 Therefore, in the scanning period T3, the scanning line L3 is enabled, and the scanning lines L1, L2, L4 to L6 are disabled. The scan line L3 enables its corresponding pixel unit such that each enabled pixel unit receives the pixel data transmitted by the corresponding data line.

之後,於掃描時段T4至T6內,主動式矩陣顯示面板的動作係依此類推,於此不再贅述。 Thereafter, during the scanning period T4 to T6, the action of the active matrix display panel is the same, and will not be described herein.

本實施例中,主動式矩陣顯示面板500係以具有6條掃描線與10個開關為例,實際應用上並不限於此。本發明之主動式矩陣顯示面板可包含較多或較少的掃描線,並配合地包括較多或較少的開關。 In this embodiment, the active matrix display panel 500 has six scanning lines and ten switches as an example, and the practical application is not limited thereto. The active matrix display panel of the present invention may include more or fewer scan lines and cooperatively include more or fewer switches.

在本實施例中,控制訊號P1與P4係可以是同一個訊號或具有相同時序之不同訊號。控制訊號P2與P3係可以是同一個訊號或具有相同時序之不同訊號。 In this embodiment, the control signals P1 and P4 may be the same signal or different signals having the same timing. The control signals P2 and P3 can be the same signal or different signals with the same timing.

在上述各實施例中,開關310、320、SW1至SW10係以NMOS來實現為例,然而實際應用上並不限於此。 In the above embodiments, the switches 310, 320, SW1 to SW10 are implemented by using an NMOS as an example, but the practical application is not limited thereto.

茲說明本實施例之主動式矩陣顯示面板之效果。以掃描線L3為例。於掃描時段T3內掃描線L3係被致能,掃描線L3的兩端分別接收被致能的控制訊號P1與被致能之掃描訊號SC3。藉由從掃描線L3的兩端輸入被致能之控制訊號與掃描訊號來致能掃描線L3,掃描線L3上各個位置的訊號波形不會因為RC效應而失真。同理,其他掃描線上的訊號波形亦不會失真。 The effect of the active matrix display panel of this embodiment will be described. Take scan line L3 as an example. The scan line L3 is enabled during the scan period T3, and both ends of the scan line L3 receive the enabled control signal P1 and the enabled scan signal SC3. The scan line L3 is enabled by inputting the enabled control signal and the scan signal from both ends of the scan line L3, and the signal waveform at each position on the scan line L3 is not distorted by the RC effect. Similarly, the signal waveforms on other scan lines are not distorted.

因此,當本實施例之主動式矩陣顯示面板朝大尺寸發展時,不會因為掃描線變長而導致掃描線上的各個位置的 訊號波形不一致。因此,相較於第1A圖之傳統液晶顯示面板,本實施例之主動式矩陣顯示面板的畫面亮度係較為均勻。故本實施例之主動式矩陣顯示面板的畫質係高於第1A圖之傳統液晶顯示面板的畫質。 Therefore, when the active matrix display panel of the present embodiment is developed toward a large size, it does not cause various positions on the scan line because the scan line becomes long. The signal waveforms are inconsistent. Therefore, the picture brightness of the active matrix display panel of the embodiment is relatively uniform compared to the conventional liquid crystal display panel of FIG. Therefore, the image quality of the active matrix display panel of this embodiment is higher than that of the conventional liquid crystal display panel of FIG. 1A.

另外,若本實施例之主動式矩陣顯示面板係包括N條掃描線,則其所配合的第一側掃描驅動器與第二側掃描驅動器總共僅需配置N+1個掃描通道輸出掃描訊號,即可正確地控制上述N條掃描線。相較之下,第2圖之傳統液晶顯示面板,若包括N條掃描線,則傳統液晶顯示面板所配合的第一側掃描驅動器與第二側掃描驅動器分別需配置N個掃描通道,即共需配置2×N個掃描通道,始可正確地控制上述N條掃描線。 In addition, if the active matrix display panel of the embodiment includes N scan lines, the first side scan driver and the second side scan driver that are matched together need only configure N+1 scan channels to output scan signals, that is, The above N scanning lines can be correctly controlled. In contrast, the conventional liquid crystal display panel of FIG. 2 includes N scanning lines, and the first side scanning driver and the second side scanning driver of the conventional liquid crystal display panel respectively need to be configured with N scanning channels, that is, a total of It is necessary to configure 2×N scanning channels to correctly control the above N scanning lines.

舉例來說,本實施例之主動式矩陣顯示面板具有6條掃描線,需要第一側掃描驅動器610提供3個掃描通道,第二側掃描驅動器620提供4個掃描通道,共7個掃描通道,即可控制上述6條掃描線。而同樣具有6條掃描線的傳統液晶顯示面板則需要第一側掃描驅動器140與第二側掃描驅動器150分別提供6個掃描通道,共12個掃描通道,始可控制上述6條掃描線。因此,本實施例之主動式矩陣顯示面板可以有效降低其所配合的掃描驅動器的掃描通道的數量,降低生產成本,與使用時的耗電量。 For example, the active matrix display panel of the embodiment has six scan lines, the first side scan driver 610 is required to provide three scan channels, and the second side scan driver 620 provides four scan channels for a total of seven scan channels. The above 6 scan lines can be controlled. The conventional liquid crystal display panel, which also has six scanning lines, requires the first side scanning driver 140 and the second side scanning driver 150 to provide six scanning channels, respectively, for a total of 12 scanning channels, and the above six scanning lines can be controlled. Therefore, the active matrix display panel of the embodiment can effectively reduce the number of scanning channels of the scan driver to which it is matched, reduce the production cost, and consume power during use.

因此,本實施例之主動式矩陣顯示面板具有低生產成本、低耗電量的特性,同時更具備較佳畫質。 Therefore, the active matrix display panel of the present embodiment has the characteristics of low production cost, low power consumption, and better image quality.

綜上所述,雖然本發明已以一較佳實施例揭露如上, 然其並非用以限定本發明。本發明所屬技術領域中具有通常知識者,在不脫離本發明之精神和範圍內,當可作各種之更動與潤飾。因此,本發明之保護範圍當視後附之申請專利範圍所界定者為準。 In summary, although the present invention has been disclosed above in a preferred embodiment, It is not intended to limit the invention. A person skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention.
