Description

用于减少画面重影的方法 A method for reducing ghost screen

技术领域 FIELD

[0001] 本发明是有关于一种用于减少画面重影的方法,特别有关于一种减少画面中不同区域的重影的方法。 [0001] The present invention relates to a method for reducing screen ghosting, particularly relates to a method of screen regions of different ghost reduction.

背景技术 Background technique

[0002] 随着显示技术的进步,液晶显示器的驱动速度也越来越快,其中又以色序法(Color Sequential)显示技术及立体(Three-Dimension, 3D)显示技术对于画面的更新速度有更高的要求。 [0002] As display technology advances, the driving speed of the liquid crystal display faster and faster, among which the color sequential (Color Sequential) and three-dimensional display technology (Three-Dimension, 3D) display technology has for a screen update speed higher requirement.

[0003] 举色序法显示技术来说,色序法显示器不使用彩色滤光片,而是使用红绿蓝R/G/B三色光,依序在R色场扫描完,点亮红光,再扫描G色场完,点亮绿光,最后再扫描B色场,最后点亮蓝光,一直照此顺序点亮来达成颜色的再现。 [0003] For color sequential display technology, a color sequential display without using a color filter, but the use of red, green and blue R / G / B three color lights in R sequentially scanned color fields, red lights , then G color field scanning finished, green lighting, and finally scanned color field B, and finally blue lights, the lighting sequence as such has been to achieve color reproduction. 但与传统驱动方式相比,一条扫描线(Gate line)导通的时间便缩短许多倍,例如:传统一个巾贞率为(frame rate) 60赫兹(Hz)(周期约16.67ms),则一条扫描信号线导通的时间约为=16.67/扫描信号线总数。 However, compared with the conventional driving method, a scanning line (Gate line) conduction time can be shortened and a number of times, for example: a conventional towel was Chen (frame rate) 60 hertz (Hz) (about 16.67 ms period), then a scanning signal line is turned on for about Total = 16.67 / scanning signal lines. 而以色序法来驱动时,一条扫描信号线导通的时间约为=16.67/(色场总数(至少三个色场画面R,G,B)X扫描信号线总数)。 While in a color sequential driven, a scanning signal line is turned about time = 16.67 / (total number of (at least three color field pictures R, G, B) the total number of color fields scanning signal line X).

[0004] 在扫描线导通的时间比原先缩短许多倍时,扫描线或是数据线(Source lines)的电阻电容延迟(RC延迟)现象将会对画面造成重影(double image)、或称为鬼影(ghostimage)。 When [0004] the scanning line is turned many times shorter than the original time, the scan lines or the data lines (Source lines) delay resistor-capacitor (RC delay) will result in a ghost phenomenon (double image) on the screen, or said as a ghost (ghostimage). 请参照图1,图1绘示习知显示装置的因RC延迟所产生的重影现象的示意图。 Referring to 1, a schematic view illustrating a conventional display apparatus due to RC delay of the ghost phenomenon generated in FIG. 1 FIG. 以分辨率1600X900的显示装置10为例,显示装置10用于显示一画面100。 In Example 1600X900 resolution of the display device 10, a display device 10 for displaying a screen 100. 该显示装置10具有一闸极驱动器200、多个源极驱动器300、1600条垂直排列的数据线(未图标)及900条水平排列的扫描线(未图标)。 The display device 10 has a gate driver 200, the data lines arranged in a plurality of vertical 300,1600 source driver (not shown) and scanning lines 900 arranged horizontally (not shown).

[0005] 请参照图1及图2A,图2A为图1中A区域的信号波型示意图,其中横轴为时间,纵轴为准位。 [0005] Referring to FIG. 1 and FIG. 2A, FIG. 2A is a schematic diagram of a signal waveform A in FIG region, wherein the horizontal axis represents time and the ordinate whichever position. 为清楚说明,将频率讯号(CLK)、数据(Data)信号、未延迟的扫描线信号及延迟的扫描线信号分别绘示在不同的垂直位置。 To clearly illustrate, the frequency signal (the CLK), data (Data) signal, the scanning signal line and the scan line delayed signal is not delayed are shown in different vertical positions. 在该画面100的A区域(右上角虚线区域)时,由于扫描线的信号是由显示装置的左端往右端传输,因此在显示画面100右端的RC延迟较为严重,造成第N条(N的范围为I到899)的扫描线信号还未完全关断时,就开始写入第N+1条扫描线信号的数据信号,导致位于第N条扫描线的液晶电容充到了第N+1条扫描线信号的数据信号,这种情形便很容易造成影像画面有上重影现象,如图1中所显示的「A」上还隐约看的到一个较不清楚且位于在当前图像之上的影像。 When the A region (upper right region of a broken line) of the screen 100, since the scanning signal lines of the display device is left to the right end of the transmission, so the right side of the display screen 100 RC delay is more severe, resulting in the N-th range (of N when I to 899) of the scan line signal has not completely turned off, it starts writing the data signals of N + 1 scanning signal lines, resulting in the liquid crystal located in the N-th scan line of the first capacitor is charged to the N + 1 th scan data signal line signal, this situation will be very easy to create images on the screen there is ghosting, as shown in a display on the "a" still vaguely see a less clear and is located above the current image of the video .

[0006] 请参照图1及图2B,图2B为图1中B区域的信号波型示意图。 [0006] Referring to FIG. 1 and FIG. 2B, FIG 2B is a schematic diagram of a signal waveform in the region B in FIG. 在B区域(左下角虚线区域)时,由于扫描时间缩短,连带影响到数据线与扫描线的关系变的更严苛。 When the region B (lower left corner of the dashed area), since the scanning time is shortened, thus influencing the relationship between the data lines and the scan lines becomes more stringent. 当数据线的RC延迟造成数据信号由显示装置的上端传送到底部的延迟,如延迟的数据信号所示。 When the data line RC delay of the delay caused by the display data signal transmitted in the end portion of the upper end of the device, such as the delayed data signal shown in FIG. 第N+1的扫描线的前端写入了第N条延迟转换的资料,此情形便很容易造成影像在显示画面100有下重影现象,如图1中所显示的「B」上还隐约看的到一个较不清楚且位于在当前图像之下的影像。 The front end of the first scan line N + 1 is written into the data delayed switching article N, in this case it is likely to result in an image with a display screen 100 under ghosting, as shown on a display in the "B" vaguely to see a less clear image and located below the current image.

[0007] 不论是上重影还是下重影皆造成了观赏者的不适。 [0007] Whether the ghost or ghosts are under the discomfort caused by the viewer. 因此,目前亟需提出一种用于减少画面重影的方法,以解决上述问题。 Therefore, it is an urgent need to propose a method for reducing ghost screen to solve the above problems.

[0044] 请参照图3,图3绘示实施第一实施例的显示装置。 [0044] Referring to FIG 3, FIG. 3 illustrates a first embodiment of the display device of the embodiment. 以分辨率1600X900的画面100为例,该画面100是划分成复数区域,并是由一显示装置10提供。 1600X900 resolution screen 100 as an example, the screen 100 is divided into a plurality of regions, and 10 is provided by a display device. 该显示装置10具有一闸极驱动器200、多个源极驱动器300、1600条垂直排列的数据线(未图标)及900条水平排列的扫描线(未图标)。 The display device 10 has a gate driver 200, the data lines arranged in a plurality of vertical 300,1600 source driver (not shown) and scanning lines 900 arranged horizontally (not shown). 该画面100具有第一区域102及第二区域104为重影较为严重的区域。 The screen 100 has a first region 102 and second region 104 is more serious ghost area. 更进一步地说,该画面100可简单的划分为3等分,其中扫描线第I至300条为于画面100的第一等份、扫描线第301至600条为于画面100的第二等份、扫描线第601至900条为于画面100的第二等份。 More particularly, the screen 100 can simply be divided into three equal portions, wherein the scanning lines 300 to I-100 in the aliquots of the first screen, the scanning line 600 to Article 301 and the like on a screen 100 of the second parts, article scanning line is 601 to 900 of the screen 100 to a second aliquot. 然而,本发明的画面100并不限于以此3等分划分,亦可划分为更多等分。 However, the screen 100 of the present invention is not limited to this division into three equal parts, can be divided into more divisions. 此外,本发明的画面100亦不限于以相同等分划分,不同大小的划分方式亦可实施的。 Further, the screen 100 of the present invention is not only restricted to the same aliquot divided, the division may be practiced embodiment different sizes.

[0045] 请参照图4以及图3,图4是根据本发明的第一较佳实施例的减少画面100重影的方法的流程图。 [0045] Referring to FIG. 4 and FIG. 3, FIG. 4 is a flowchart of a method of reducing a screen of a first preferred embodiment of the present invention is 100 ghost. 该方法开始于步骤S10。 The method starts at step S10.

[0046] 在步骤SlO中,产生复数个致能(Output Enable, 0E)讯号,该些输出致能讯号用于分别调整对应该些区域(如第一区域102及第二区域104)的该些扫描线的复数个导通期间,特别是根据减少第一区域102及第二区域104的重影调整该些扫描线的该些导通期间。 [0046] In step SlO, the generating a plurality of enabled (Output Enable, 0E) signal, the plurality of output enable signal should be adjusted for each of these areas (e.g., first region 102 and second region 104) of the plurality of during the period of the plurality of conducting a plurality of scanning lines is turned on, in particular, to adjust the plurality of scan lines in accordance reduce ghosting 102 and the second region 104 of the first region. 在此较佳实施例中,调整该些导通期间是缩短该些导通期间方式实施。 In the preferred embodiment, the plurality of adjustment is to reduce the conduction period of the plurality of mode-period embodiment.

[0047] 在步骤S20中,输出该些输出致能讯号到该闸极驱动器200以产生对应该些区域(如第一区域102及第二区域104)的复数个扫描讯号。 [0047] In step S20, the output of the plurality of output enable signal to the gate driver 200 to produce a plurality of scan signals of these regions should be (e.g., first region 102 and second region 104).

[0048] 请参照图5A和图6,图5A为图3中第一区域102的信号波型示意图。 [0048] Referring to FIGS. 5A and FIG. 6, FIG. 5A signal waveform is a schematic view of a first region 102 in FIG. 3. 为清楚说明,将频率讯号(CLK)、数据信号、未延迟的扫描线信号GO及延迟的扫描线信号G1、输出致能讯号OEl及实际的扫描线信号G2分别绘示在不同的垂直位置。 To clearly illustrate, the frequency signal (the CLK), the data signal, the scan line signal G1 scan line signal GO and a delay is not delayed, the output enable signal OEl and the actual scan line signal G2 respectively show different vertical positions. 该些输出致能讯号是由时序控制器(TCON)(未图示)提供给该闸极驱动器200,输出致能讯号用以控制扫描线的导通期间。 The plurality of output enable signal, the output enable signal during a scanning line for controlling conduction provided to the gate driver by the timing controller (the TCON) (not shown) 200.

[0049] 该输出致能讯号可透过设定,使得当该输出致能讯号位于高准位时,对应的扫描线则关断。 [0049] The output enable signal set permeable, such that when the output enable signal in the high level, the corresponding scanning line is turned off. 该输出致能讯号同样地可透过设定,使得当该输出致能讯号位于高准位时,对应的扫描线则导通。 The output enable signal in the same manner using set, such that when the output enable signal in the high level, the corresponding scan line is turned on. 在此较佳实施例中,该输出致能讯号OEl是设定位于高准位时,对应的扫描线则关断。 In the preferred embodiment, the output enable signal OEl is set in the high level, the corresponding scanning line is turned off.

[0050] 在该画面100的第一区域102中,扫描线的RC延迟较为严重,其扫描线信号传输至第一区域102即如延迟的扫描线信号Gl所示,会有一个尾巴的延迟。 [0050] In the first region 102 of the screen 100, the RC delay of the scanning lines is serious, which is shown in the scanning line Gl signal transmitted to the first scan line signal 102, ie The delay region, there will be a delay tail. 因此,缩短该些扫描线导通期间是提早关断该些扫描线。 Thus, to shorten the period of the plurality of scanning lines is turned off earlier the plurality of scan lines. 透过该输出致能讯号OEl在该扫描线导通期间的后段设定为高准位,藉此提早关断该扫描线,如实际的扫描线信号G2所示。 Transmitted through the output enable signal OEl set after the period during which the scanning line is turned to high level, thereby turning off the earlier scan line, as indicated by the actual scan line signal G2. 如此使得该扫描线的RC延迟(即讯号的尾巴)提早被抑制。 So that the RC delay of the scanning line (i.e., the tail of the signal) is suppressed earlier. 因此,对应该扫描线的画素因而不会被写入下一个数据信号,减轻了第一区域102的上重影。 Thus, the scanning lines of pixels should therefore not be written to the next data signal, reduce the ghost of the first region 102.

[0051] 请参照图5B和图6,图5B为图3中第二区域104的信号波型示意图。 [0051] Referring to FIGS. 5B and FIG. 6, FIG. 5B is a schematic diagram of the signal waveform 104 in FIG. 3 of the second region. 同样地,将频率讯号(CLK)、未延迟的数据信号S0、延迟的数据信号S1、扫描线N信号、扫描线N+1信号、输出致能讯号0E3、实际的扫描线N信号Gn及实际的扫描线N+1信号Gn+1分别绘示在不同的垂直位置。 Likewise, the frequency signal (the CLK), the undelayed data signal S0, the delayed data signals S1, scan line N signal, the scanning line N + 1 signals, output enable signals 0E3, the actual scan line N signal Gn and actual N + 1 scanning line Gn + 1 signals are shown in different vertical positions. 在此较佳实施例中,该输出致能讯号0E3是设定位于高准位时,对应的扫描线则关断。 In the preferred embodiment, the output enable signal 0E3 is set in the high level, the corresponding scanning line is turned off.

[0052] 在该画面100的第二区域104中,数据线的RC延迟较为严重,其数据线信号传输至第二区域104即如延迟的数据线信号SI所示。 [0052] In the second region 104 of the screen 100, the RC delay of the data lines is serious, which is transmitted to the second data line signal The data region 104 i.e. the delay line signal SI shown in FIG. 因此,缩短该些导通期间是延后导通该些扫描线。 Thus, to shorten the period of the plurality of delay is turned ON the plurality of scan lines. 透过该输出致能讯号0E3在该扫描线导通期间的前段设定为高准位,藉此延迟导通该扫描线,如实际的扫描线N信号Gn及扫描线N+1信号Gn+1所示。 Transmitted through the output enable signal 0E3 preceding scanning line is set in the ON period at the high level, thereby turning on the scanning line delay, if the actual scanning line signal Gn N N + 1 and the scanning signal line Gn + 1 shown in FIG. 如此使得该扫描线N+1的未写入于延迟的数据信号SI。 So that the scan line N + 1 data is not written to the delayed signal SI. 因此,对应该扫描线N+1的画素因而不会被写入上一个数据信号,减轻了第二区域104的下重影。 Therefore, the pixels should scan line N + 1 and thus will not be written on a data signal to reduce the ghost at the second region 104. [0053] 请参照图3及图6,图6为第一实施例的3等分区域的信号波型示意图。 [0053] Referring to FIG. 3 and FIG. 6, FIG. 6 is a signal waveform diagram 3 equally divided region of the first embodiment. 各输出致能讯号是用于调整该些区域中的一对应区域的扫描线的导通期间。 Each output enable signal for adjusting the conduction period of the scanning line corresponding to a region of the plurality of regions. 举例来说,该画面100分为3等分,且N代表为全部的扫描线数目,例如900条扫描线。 For example, the screen 100 is divided into three equal portions, and N represents the number of all the scanning lines, for example, 900 scan lines. 该些输出致能讯号OE具有3个0E1、0E2及0E3,分别用以调整画面100的第一等份、第二等份及第3等分对应的该些扫描线I至300、301至600、及601至900的复数个导通期间。 The plurality of output enable signal OE has three 0E1,0E2 and 0E3, respectively, for adjusting the screen 100 of the first aliquot and the second aliquot third aliquot corresponding to the plurality of scan lines 300, 301 to I-600 , and during a plurality of conductive 601-900. 该些输出致能讯号0E1、0E2及0E3分别对应至该些区域的该些扫描线。 The plurality of output enable signal 0E1,0E2 0E3 and corresponding to the plurality of scan lines of the plurality of regions. 其中减少画面100的第一等分(特别是第一区域102)的重影如上述图5A说明,提供给该些扫描线I至300的输出致能讯号如OEl所示,是用于提早关断该些扫描线I至300以减少上重影。 Wherein a first aliquot of reduced screen 100 (in particular the first region 102) as a ghost in FIG. 5A described above, is supplied to the plurality of scan lines to the output enable signal I 300 OEl as shown, for early Off breaking the plurality of scan lines 300 to I to reduce the ghosting.

[0054] 同样地,减少画面100的第3等分(特别是第二区域104)的重影如上述图5B说明,提供给该些扫描线601至900的输出致能讯号如0E3所示,是用于延后导通该些扫描线601至900以减少下重影。 [0054] Similarly, aliquots of the third screen 100 to reduce (in particular, the second region 104) of the ghost as described above in FIG. 5B, the output is supplied to the plurality of scan lines 601-900 of the enabling signal as shown 0E3, Snooze for conducting the plurality of scan lines 601 to 900 to reduce the ghosting.

[0055] 该画面100的第二等份的重影是介于第一等分的上重影及第二等分的下重影之间,因此该些扫描线301至600需延后导通以及提早关断,藉此减少画面100的第二等分的重影。 [0055] The second aliquot of the screen 100 is interposed between the ghost and the ghost ghosting second aliquot of the first aliquot, and therefore the plurality of scan lines 301 to 600 for an ON delay and off early, thereby reducing second aliquot of the screen 100 ghosting. 据此,提供给该些扫描线601至900的输出致能讯号如0E2所示,是用于需延后导通以及提早关断该些扫描线601至900以缩短对应的导通期间。 Accordingly, an output is provided to the plurality of scan lines 601-900 of the actuation signal can be shown as 0E2, the need for delay is turned off early and the plurality of scan lines 601-900 to shorten the conduction period corresponding.

[0056] 在步骤S30中,该闸极驱动器200根据该些扫描讯号驱动对应该些区域的复数条扫描线。 [0056] In step S30, the gate driver 200 to the plurality of scan lines in these areas should be based on the plurality of scan driving signal. 需注意的是,该些扫描讯号是经过该些输出致能讯号作用后的实际扫描线I至900的信号,其中扫描线I至300的导通期间缩短为Tl、扫描线301至600的导通期间缩短为T2、扫描线601至900的导通期间缩短为T3,且T1、T2及T3较佳是为相同的。 Note that, the plurality of scan signal is a signal 900 through the plurality of outputs of the enable signal effect the actual scan lines I to, wherein the scan lines I to shorten the conduction period 300 is Tl, guiding the scanning lines 301 to 600 to reduce the period through T2, the scanning lines 601 to 900 of the conduction period is shortened T3, and T1, T2 and T3 are preferably the same.

[0057] 可以理解的是,本发明的用于减少画面重影的方法不限于对该画面100分为3等分,亦可分为5、10及其它更多等分来更精细的调整各个区域的重影。 [0057] It will be appreciated that the present invention is a screen for reducing ghosting method is not limited to the screen 100 is divided into three aliquots, it can be divided into more equal parts, and other 5,10 finer adjustment of each ghost area. 举一极端例子,各输出致能讯号是用于调整该些扫描线的其中一条对应的扫描线的导通期间。 The conduction period of the scanning line cite an extreme example, each of the output enable signal is used to adjust the plurality of scan lines corresponding to one of. 具体而言,该画面可分成对应每一条扫描线的区域,即分成N个区域,N为全部扫描线的个数,并提供每一条扫描线个别的输出致能讯号以减少每一条的重影,该些输出致能讯号是根据减少对应每一该些扫描线的重影调整每一该些扫描线的导通期间。 Specifically, the screen may be divided into a region corresponding to each scan line, i.e., into N regions, the number N of all the scanning lines, and to provide individual output enable each scan line signal to reduce each ghost , the plurality of output enable signal is reduced according to the conduction period corresponding to each of the scan lines ghost adjustment of each of the scan lines. 请参照图7,图7为第一实施例的每一条扫描线的信号波型示意图。 Referring to FIG 7, FIG 7 is a schematic diagram of a signal waveform for each scan line according to the first embodiment. 在此实施例中,N为900,因此原始的扫描线I至900 (即N)的信号皆使得扫描线I至900导通期间为完整的一个频率周期。 In this embodiment, N is 900, so the original I to 900 scanning lines (i.e., N) are such that the scanning signal lines I to 900 for the conduction period of a complete clock cycle.

[0058] 同样地,在步骤SlO所提供的输出致能讯号则同样具有900个,如0E1、0E2...0E900,其中每一该些输出致能讯号分别对应至每一该些扫描线。 [0058] Similarly, in step SlO the output enable signal provided to the actuator 900 also has, as 0E1,0E2 ... 0E900, wherein each of the output enable signals respectively corresponding to each of the scan lines. 在步骤S20中,输出该些输出致能讯号0E1、0E2-0E900到该闸极驱动器200,以产生实际对应的扫描线I信号、扫描线2信号…扫描线N信号。 In step S20, output the plurality of output enable signal 0E1,0E2-0E900 to the gate driver 200 to generate the actual signal I corresponding scanning line, the scanning signal line 2 ... N scan line signal. 在步骤S30中,该闸极驱动器200根据扫描线I信号、扫描线2信号…扫描线N信号驱动对应该些区域(即900个区域)的扫描线1、扫描线2…扫描线N。 In step S30, the gate driver 200 drives the scan lines according to a signal I signal, the scanning signal line 2 ... N scanning lines of the scanning lines should these regions (i.e., regions 900) of a scanning line the scanning lines 2 ... N.

[0059] 在第一实施例中,除了将画面100划分为多个水平区域之外,还可将该画面100划分为数个垂直区域以做更精细的调整。 [0059] In the first embodiment, except that the screen 100 is divided into a plurality of level regions, also the screen 100 is divided into several regions perpendicular to do finer adjustment. 请参考图8A,图8A绘示图3的画面100的水平分区增加垂直分区。 Please refer to FIG. 8A, FIG. 8A shows a screen of the horizontal partitions 3 a vertical partition 100 increases. 在此实施例中,该显示装置具有5个源极驱动器300,因此将该垂直分区分为对应的第一分区310至第五分区350。 In this embodiment, the display device 5 having a source driver 300, and therefore the vertical partition into a first partition 310 to partition 350 corresponding to the fifth.

[0060] 因此,在第一实施例中,减少画面100重影的方法的还包括产生复数个闩锁数据(latch data, LD)讯号,该些闩锁数据讯号用于分别调整对应该些区域的该些数据线的复数个数据输出时间。 [0060] Thus, in a first embodiment, a method of reducing ghost screen 100 further includes generating a plurality of data latches (latch data, LD) signal, the plurality of data latch signal should be adjusted for each of these areas a plurality of the data lines of data output time. 输出该些闩锁数据LD讯号到该些源极驱动器300,以产生对应该些区域的复数个画素数据讯号。 These outputs the latched data LD signal to the plurality of source driver 300, to produce a plurality of pixel data signals to be some areas. 最后,该些源极驱动器根据该些画素数据讯号驱动对应该些区域的该些数据线。 Finally, the plurality of source driver should drive some of the data lines of the region according to the plurality of pixel data signals.

[0061] 请参照图9A至图9D,图9A为图8A中第一及第二分区的信号波型示意图、图9B为图8A中第三分区的信号波型示意图、图9C为图8A中第四分区的信号波型示意图及图9D为图8A中第五分区的信号波型示意图。 [0061] Referring to FIGS. 9A to Figure 9D, FIG. 9A and FIG. 8A of the first signal waveform diagram of a second partition, Fig. 9B is a signal waveform diagram illustrating a third partition of FIG. 8A, FIG. 8A to FIG. 9C schematic signal waveform and FIG. 9D is a schematic diagram of a fourth partition of the signal waveform in FIG. 8A fifth partition. 具体而言,该些闩锁数据信号是由时序控制器(TCON)(未图示)分别提供给些源极驱动器300,当源极驱动器300将数据转变控制信号(数字转成模拟)时,当闩锁数据信号在下降缘(falling edge)时,则触发源极驱动器300输出数据所对应的准位。 Specifically, the plurality of latched data signals are provided by the timing controller (the TCON) (not shown), respectively, to the plurality of source drivers 300, when the source driver 300 converts the data to a control signal (digital to analog switch), the when the data latch 300 outputs the data signal at the falling edge (falling edge), the trigger source driver corresponding level.

[0062] 该画面100分为五个分区,越靠近第五分区350的扫描线的RC延迟越严重,严重程度为第五分区350〉第四分区340〉第三分区330〉第二分区320〉第一分区310,故我们将每个源极驱动器300的闩锁数据讯号分为LDl至LD5对该些分区做个别控制,说明如下。 [0062] The screen 100 is divided into five partitions, the closer to a fifth scan line RC delay of more serious partition 350, fifth partition 350 severity> fourth partition 340> third partition 330> Second partition 320> a first partition 310, so we each source driver 300 data signals latched into the LDl to LD5 these partitions do individual control, described below.

[0063] 请参照图9A,在第一分区310及第二分区320中,由于距离闸极驱动器200较近,因此扫描线的RC延迟较不明显(尾巴较短),从而将LDl及LD2的下降缘时间设定为T0,以控制在脉冲周期刚开始即发出第一分区310及第二分区320的数据线所对应的准位。 [0063] Referring to Figure 9A, in the first partition 310 and second partition 320, due to the extremely close distance from the gate driver 200, the scanning line RC delay and therefore less pronounced (short tail), thereby LDl and LD2 of falling edge time is set to T0, to control the emitted pulse cycle i.e. the beginning of a first partition 310 and the second data line 320 corresponding to the partition level.

[0064] 请参照图9B,在第三分区330中,扫描线的RC延迟逐渐明显,从而将LD3的下降缘时间延迟为Tl,以控制在脉冲周期开始Tl时间后才发出第三分区330的数据线所对应的准位。 [0064] Referring to FIG. 9B, the third partition 330, the scanning line RC delay became clear, so that the falling edge of the delay time LD3 Tl, Tl after the start time to control the pulse period of issuing the third partition 330 corresponding to the data line level.

[0065] 请参照图9C,在第四分区340中,扫描线的RC延迟较为明显,从而将LD4的下降缘时间延迟为T2,以控制在脉冲周期开始T2时间后才发出第四分区340的数据线所对应的准位。 [0065] Referring to Figure 9C, in the fourth partition 340, the scanning line RC delay is more obvious, so LD4 falling edge time delay of T2, to control the pulse period after the start time T2 of the fourth partition 340 is sent corresponding to the data line level.

[0066] 请参照图9D,在第五分区350中,扫描线的RC延迟较为明显,从而将LD5的下降缘时间延迟为T3,以控制在脉冲周期开始T3时间后才发出第五分区350的数据线所对应的准位。 [0066] Referring to Figure 9D, the fifth partition 350, the RC delay of the scanning lines more obvious so that the falling edge of the delay time T3 LD5, to control the time T3 after the cycle start pulse emitted fifth partition 350 corresponding to the data line level. 其中下降缘延迟的关系为T3>T2>T1>T0,并调整到上重影消失为止。 Wherein a relationship falling edge delay T3> T2> T1> T0, and adjusted to the ghost disappears. 简言之,闩锁数据讯号LD是延后该些数据信号的输出期间,以配合延迟的扫描信号线而减少重影。 Briefly, the data latch signal LD ​​is delayed during the plurality of data signal output to match the delay of the scanning signal lines reduce ghosting.

[0067] 由上述可知,本发明的画面重影的方法可同时利用及闩锁数据讯号LD及输出致能讯号OE分区改善画面的重影。 [0067] From the foregoing, the screen ghosting process of this invention may be utilized at the same time and the data latch signal LD ​​and the output enable signal OE of the partition improving the ghost images. 请参照图8B,图8B绘示图8A的区域示意图。 Referring to Figure 8B, FIG. 8A 8B a schematic diagram of a schematic region. 在图8B中的区域1、I1、II1、IV中,由于扫描线的RC延迟,所以会较容易出现上重影。 In FIG. 8B region 1, I1, II1, IV, since the scanning line RC delay, it will be easier for the ghost appears. 因此可以控制第四分区340及第五分区350 (如图8A所示)的LD4及LD5,让延迟的扫描信号线第N条尚未关断时,还保持着第N笔的数据,不至于去写入正在转变的第N+1笔数据,其信号波型示意图,如图9C及图9D所示。 It is possible to control the fourth and fifth partition 340 partitions 350 (FIG. 8A) of LD4 and LD5, so that the scanning signal line delayed when not turned off, the N-th pen also holds article data N, and will not go the first N + 1 pieces of data being written to the transition, the signal waveform diagram shown in FIG. 9C and FIG. 9D.

[0068] 在图8B中的区域V中,可利用输出致能讯号OE减少区域V的下重影。 [0068] In the region V in FIG. 8B, may be utilized to reduce the output enable signal OE of the V region of ghost. 请参照图10,图10为图SB的扫描线信号波型示意图。 Referring to FIG 10, FIG 10 is a diagram of the scan line signal SB schematic waveform. 区域V位于该画面100的水平的第3等分,因此该区域V(扫描线为2N/3+1〜N,如601至900)的输出致能讯号即为上述图6的0E3示。 V is located in the region of 100 horizontal picture aliquots of 3, so that the region V (the scanning lines of 2N / 3 + 1~N, such as 601 to 900) is the output enable signal shown in FIG. 6 0E3. 因此,原始的扫描线2N/3+1〜N的信号作用后即如实际的扫描线2N/3+1〜N的信号,用于延后导通该些扫描线601至900以减少下重影。 Thus, the role of the original scanning line signal 2N / 3 + 1~N The signal after the actual scanning lines 2N / 3 + 1~N for re-conducting the plurality of scan delay lines 601-900 to reduce the shadow.

[0069] 由于区域1、I1、II1、IV已由闩锁数据讯号LD的控制减少了重影,因此位于画面100的第一等分及第二等分的扫描线则不需再由输出致能讯号OE作用。 [0069] Since the region 1, I1, II1, IV by the data latch control signal LD ​​is reduced ghosting, thus positioned in the first aliquot and the second aliquot screen 100 scanning lines is output by the actuator without further enable signal OE role. 具体来说,OE I〜2N/3全为低准位,因此实际的扫描线I至2N/3信号波型还是与原始的一样。 Specifically, OE I~2N / 3 are all low level, the actual scanning lines I to 2N / 3 the original signal waveform or the like. 需注意的是,本发明并不限于此种划分方式,亦可将该画面100划分为更多区域,以作更精细的调整。 It should be noted that the present invention is not limited to such division manner, the screen 100 may be divided into more areas, to make finer adjustments. [0070] 综上所述,本发明第一实施例的用于减少画面重影的方法利用了多个输出致能讯号OE对画面不同区域的重影做个别的改善,更甚者是提供与扫描线个数相同的输出致能讯号0E,以减少每一条扫描在线的重影。 [0070] In summary, the first embodiment of the present invention for reducing the screen embodiment of the method utilizes a ghost plurality of output enable signal OE of ghost images in different regions to be improved other Worse still provide the same number of scan line output enable signal 0E, each scan line to reduce the ghost. 此外,第一实施例的用于减少画面重影的方法还结合了产生多个闩锁数据讯号以对画面不同的垂直区域做调整,完整的克服了扫描线以及数据线的RC延迟的问题。 Further, the method for reducing the picture of the first embodiment also incorporates a ghost generating a plurality of data latches to the picture signal a different vertical region to make adjustments to overcome the problem of a complete scanning line and the data line RC delay.

[0071] 以下将说明本发明的用于减少画面重影的方法的第二实施例。 [0071] The second embodiment of a method for reducing ghost screen of the present invention will be described below. 与第一实施例不同的是,第二实施例是先将该画面100划分为复数个垂直区域,再利用前述的闩锁数据讯号LD控制该些区域的数据线讯号,以减少部分区域的重影。 Of the first embodiment except that the second embodiment is the first screen 100 is divided into a plurality of vertical regions, and then using the data latch signal LD ​​of the control data signal line of the plurality of regions, to reduce the weight section area shadow. 进一步还可将该画面100划分为复数个水平区域,再利用输出致能讯号OE控制扫描线讯号以减少其它区域的重影。 The screen 100 may be further divided into a plurality of level regions, and then using the output enable signal OE signal for controlling the scanning lines reduce ghosting other regions. 其中与第一实施例的相同部分在此及不再赘述。 Wherein the same parts of the first embodiment and will not be repeated herein.
