亮度均勻的雙閘極液晶顯示器Uniform brightness double gate liquid crystal display

本發明係有關於一種液晶顯示器，尤指一種可改善垂直線的亮度均勻的雙閘極液晶顯示器。The present invention relates to a liquid crystal display, and more particularly to a dual gate liquid crystal display which can improve the uniformity of brightness of a vertical line.

請參照第1圖，第1圖係為說明雙閘極液晶顯示器100的示意圖，其中雙閘極液晶顯示器100係為點極性反轉(dot inversion)的液晶顯示器。如第1圖所示，雙閘極液晶顯示器100中耦接於整合型驅動電路102的閘極線數目加倍，而耦接於整合型驅動電路102的源極線數目減半，亦即雙閘極液晶顯示器100中的一列像素係由2條閘極線驅動。例如雙閘極液晶顯示器100中的第一列像素L1係由2條閘極線G1與G2驅動。如第1圖所示，因為雙閘極液晶顯示器100中耦接於整合型驅動電路102的閘極線數目加倍，所以每條閘極線的充電時間，只有單閘極(single gate)液晶顯示器的充電時間的一半。如此，易造成在雙閘極液晶顯示器100中子像素的極性反轉時，子像素充電不足的現象。另外，S1-S5係為雙閘極液晶顯示器100中的源極線，R係為紅色子像素、G係為綠色子像素及B係為藍色子像素。Please refer to FIG. 1 , which is a schematic diagram illustrating a dual gate liquid crystal display 100 in which a dual gate liquid crystal display 100 is a dot inversion liquid crystal display. As shown in FIG. 1 , the number of gate lines coupled to the integrated driving circuit 102 in the dual gate liquid crystal display 100 is doubled, and the number of source lines coupled to the integrated driving circuit 102 is halved, that is, double gate. A column of pixels in the polar liquid crystal display 100 is driven by two gate lines. For example, the first column of pixels L1 in the dual gate liquid crystal display 100 is driven by two gate lines G1 and G2. As shown in FIG. 1 , since the number of gate lines coupled to the integrated driving circuit 102 in the double gate liquid crystal display 100 is doubled, the charging time of each gate line is only a single gate liquid crystal display. Half of the charging time. Thus, it is easy to cause a phenomenon in which the sub-pixels are insufficiently charged when the polarity of the sub-pixels in the double-gate liquid crystal display 100 is reversed. Further, S1-S5 is a source line in the double-gate liquid crystal display 100, R is a red sub-pixel, G is a green sub-pixel, and B is a blue sub-pixel.

請參照第2圖，第2圖係為說明雙閘極液晶顯示器100的閘極線驅動時序的示意圖。如第2圖所示，閘極線G1-G8依序被驅動，且每一閘極線的驅動時間一樣長，則在子像素的極性反轉時，子像素充電會不足，其中VCOM係為雙閘極液晶顯示器100的共同電壓。例如，閘極線G1(子像素對應+極性)→ 閘極線G2(子像素對應-極性)，閘極線G3(子像素對應-極性)→ 閘極線G4(子像素對應+極性)，所以對應於閘極線G2和閘極線G4的子像素會有充電不足的現象。Please refer to FIG. 2, which is a schematic diagram illustrating the gate line driving timing of the dual gate liquid crystal display 100. As shown in FIG. 2, the gate lines G1-G8 are sequentially driven, and the driving time of each gate line is as long as the sub-pixel charging is insufficient when the polarity of the sub-pixel is reversed, wherein VCOM is The common voltage of the dual gate liquid crystal display 100. For example, the gate line G1 (sub-pixel corresponding + polarity) → gate line G2 (sub-pixel corresponding - polarity), gate line G3 (sub-pixel corresponding - polarity) → gate line G4 (sub-pixel corresponding + polarity), Therefore, the sub-pixels corresponding to the gate line G2 and the gate line G4 may be insufficiently charged.

請參照第3圖，第3圖係為說明雙閘極液晶顯示器100出現垂直線(Vertical line)的示意圖。如第3圖所示，當閘極線G1-G8係以Z字型開啟雙閘極液晶顯示器100包含的複數個子像素時，因為對應於閘極線G2和閘極線G4的子像素會有充電不足的現象，所以對應於閘極線G2和閘極線G4的子像素會偏亮，而對應於閘極線G1和閘極線G3的子像素則相對偏暗。如此，雙閘極液晶顯示器100的奇數行子像素較暗以及偶數行子像素較亮。另外，如第3圖所示，R係為紅色子像素、G係為綠色子像素及B係為藍色子像素。Please refer to FIG. 3, which is a schematic diagram showing the vertical line of the double-gate liquid crystal display 100. As shown in FIG. 3, when the gate lines G1-G8 turn on a plurality of sub-pixels included in the dual-gate liquid crystal display 100 in a zigzag pattern, since the sub-pixels corresponding to the gate line G2 and the gate line G4 will be Since the phenomenon of insufficient charging is performed, the sub-pixels corresponding to the gate line G2 and the gate line G4 are bright, and the sub-pixels corresponding to the gate line G1 and the gate line G3 are relatively dark. As such, the odd row sub-pixels of the dual gate liquid crystal display 100 are darker and the even row sub-pixels are brighter. Further, as shown in FIG. 3, R is a red sub-pixel, G is a green sub-pixel, and B is a blue sub-pixel.

請參照第4圖至第8圖，第4圖至第8圖係為說明雙閘極液晶顯示器出現垂直線的示意圖。如第4圖所示，當雙閘極液晶顯示器係為2點極性反轉(2 dot inversion)的液晶顯示器且閘極線係以Z字型開啟雙閘極液晶顯示器包含的複數個子像素時，則雙閘極液晶顯示器的奇數行子像素較亮以及偶數行子像素較暗；如第5圖所示，當雙閘極液晶顯示器係為1+2點極性反轉(1+2 dot inversion)的液晶顯示器且閘極線係以Z字型開啟雙閘極液晶顯示器包含的複數個子像素時，則雙閘極液晶顯示器的奇數行子像素較暗以及偶數行子像素較亮。另外，第6圖至第8圖係為說明雙閘極液晶顯示器的閘極線係以反Z字型開啟雙閘極液晶顯示器包含的複數個子像素，則第6圖至第8圖的垂直線產生位置和第3圖至第5圖的垂直線產生位置相反，在此不再贅述。另外，如第4圖至第8圖所示，R係為紅色子像素、G係為綠色子像素及B係為藍色子像素。Please refer to FIG. 4 to FIG. 8 . FIG. 4 to FIG. 8 are schematic diagrams showing vertical lines appearing in the double gate liquid crystal display. As shown in FIG. 4, when the dual-gate liquid crystal display is a 2-dot inversion liquid crystal display and the gate line turns on a plurality of sub-pixels included in the dual-gate liquid crystal display in a zigzag manner, The odd gate sub-pixels of the dual-gate liquid crystal display are brighter and the even-numbered row sub-pixels are darker; as shown in FIG. 5, when the double-gate liquid crystal display is 1+2 dot polarity inversion (1+2 dot inversion) When the liquid crystal display and the gate line open a plurality of sub-pixels included in the dual-gate liquid crystal display in a zigzag type, the odd-line sub-pixels of the double-gate liquid crystal display are darker and the even-numbered line sub-pixels are brighter.

同理，如第9圖和第4圖所示，當液晶面板902係為2點極性反轉的液晶面板且閘極線G1-Gn係以Z字型開啟液晶面板902包含的子像素時，因為對應於閘極線G1和閘極線G3的子像素會有充電不足的現象，所以對應於閘極線G1和閘極線G3的子像素會偏亮(亦即對應於奇數條閘極線G1、G3...的子像素會偏亮)，而對應於閘極線G2和閘極線G4的子像素則相對偏暗(亦即對應於偶數條閘極線G2、G4...的子像素會偏暗)。如此，液晶面板902的奇數行子像素較亮以及偶數行子像素較暗。因為對應於偶數條閘極線G2、G4...的子像素充電足夠，而對應於奇數條閘極線G1、G3...的子像素充電不足，所以第二閘極訊號產生器9046係接收對應於偶數條閘極線G2、G4...的N/2個第一驅動訊號(FGS2、FGS4...等)和耦接於偶數條閘極線(G2、G4...等)，並根據對應於偶數條閘極線G2、G4...的N/2個第一驅動訊號(FGS2、FGS4...等)，產生對應於偶數條閘極線G2、G4...的N/2個第二驅動訊號(SGS2、SGS4...等)，其中第一驅動訊號的訊號長度係比對應的第二驅動訊號的訊號長度大預定值TG。因此，奇數條閘極線G1、G3...的充電狀況會和偶數條閘極線G2、G4...的充電狀況接近。如此，可改善液晶面板902的垂直線問題。另外，在本發明的另一實施例中，第二閘極訊號產生器9046係根據N個第一驅動訊號中對應於奇數條閘極線G1、G3...的N/2個第一驅動訊號，產生對應於奇數條閘極線G1、G3...的N/2個第二驅動訊號。此時，第二閘極訊號產生器9046係接收對應於奇數條閘極線G1、G3...的N/2個第一驅動訊號(FGS1、FGS3...等)和耦接於奇數條閘極線(G1、G3...等)，並根據對應於奇數條閘極線G1、G3...的N/2個第一驅動訊號(FGS1、FGS3...等)，產生對應於奇數條閘極線G1、G3...的N/2個第二驅動訊號(SGS1、SGS3...等)，其中第一驅動訊號的訊號長度係比對應的第二驅動訊號的訊號長度小預定值TG。如此，對應於奇數條閘極線G1、G3...的子像素的充電狀況會和對應於偶數條閘極線G2、G4...的子像素的充電狀況接近，液晶面板902的垂直線問題可被改善。另外，在本發明的另一實施例中，對應於偶數條閘極線G2、G4...的第一驅動訊號(FGS2、FGS4...等)的電壓準位係比第二閘極訊號產生器9046所產生的第二驅動訊號(SGS2、SGS4...等)的電壓準位大預定值TG。因為第二閘極訊號產生器9046所產生的第二驅動訊號(SGS2、SGS4...等)係對應於偶數條閘極線G2、G4...，所以偶數條閘極線G2、G4...的充電狀況會和奇數條閘極線G1、G3...的充電狀況接近。如此，可改善液晶面板902的垂直線問題。另外，在本發明的另一實施例中，第二閘極訊號產生器9046係根據N個第一驅動訊號中對應於奇數條閘極線G1、G3...的N/2個第一驅動訊號，產生對應於奇數條閘極線G1、G3...的N/2個第二驅動訊號，其中對應於奇數條閘極線G1、G3...的第二驅動訊號(SGS1、SGS3...等)的電壓準位係比對應於奇數條閘極線G1、G3...的第一驅動訊號(FGS1、FGS3...等)的電壓準位大預定值TG。如此，對應於奇數條G1、G3...閘極線的子像素的充電狀況會和對應於偶數條G2、G4...閘極線的子像素的充電狀況接近，液晶面板902的垂直線問題可被改善。Similarly, as shown in FIG. 9 and FIG. 4, when the liquid crystal panel 902 is a liquid crystal panel with a 2-point polarity inversion and the gate lines G1-Gn turn on the sub-pixels included in the liquid crystal panel 902 in a zigzag manner, Since the sub-pixels corresponding to the gate line G1 and the gate line G3 may be undercharged, the sub-pixels corresponding to the gate line G1 and the gate line G3 may be brighter (that is, corresponding to an odd number of gate lines). The sub-pixels of G1, G3, ... are brighter, and the sub-pixels corresponding to the gate line G2 and the gate line G4 are relatively dark (that is, corresponding to the even-numbered gate lines G2, G4, ...). Subpixels will be darker). As such, the odd row sub-pixels of the liquid crystal panel 902 are brighter and the even row sub-pixels are darker. Since the sub-pixels corresponding to the even-numbered gate lines G2, G4, . . . are sufficiently charged, and the sub-pixels corresponding to the odd-numbered gate lines G1, G3, . . . are insufficiently charged, the second gate signal generator 9046 is Receiving N/2 first driving signals (FGS2, FGS4, etc.) corresponding to the even-numbered gate lines G2, G4, ... and coupling to even-numbered gate lines (G2, G4, etc.) And generating corresponding to the even-numbered gate lines G2, G4, ... according to N/2 first driving signals (FGS2, FGS4, etc.) corresponding to the even-numbered gate lines G2, G4, ... N/2 second driving signals (SGS2, SGS4, etc.), wherein the signal length of the first driving signal is greater than the signal length of the corresponding second driving signal by a predetermined value TG. Therefore, the charging state of the odd-numbered gate lines G1, G3, ... is close to the charging state of the even-numbered gate lines G2, G4, .... As such, the vertical line problem of the liquid crystal panel 902 can be improved. In addition, in another embodiment of the present invention, the second gate signal generator 9046 is based on N/2 first drivers corresponding to the odd gate lines G1, G3, ... among the N first driving signals. The signal generates N/2 second driving signals corresponding to the odd gate lines G1, G3, . At this time, the second gate signal generator 9046 receives N/2 first driving signals (FGS1, FGS3, ..., etc.) corresponding to the odd gate lines G1, G3, ... and is coupled to the odd-numbered strips. Gate lines (G1, G3, etc.) and corresponding to N/2 first drive signals (FGS1, FGS3, etc.) corresponding to the odd gate lines G1, G3, ... N/2 second driving signals (SGS1, SGS3, etc.) of the odd gate lines G1, G3, ..., wherein the signal length of the first driving signal is smaller than the signal length of the corresponding second driving signal The predetermined value TG. Thus, the charging state of the sub-pixels corresponding to the odd-numbered gate lines G1, G3, ... is close to the charging state of the sub-pixels corresponding to the even-numbered gate lines G2, G4, ..., and the vertical line of the liquid crystal panel 902 The problem can be improved. In addition, in another embodiment of the present invention, the voltage levels of the first driving signals (FGS2, FGS4, etc.) corresponding to the even-numbered gate lines G2, G4, . . . are lower than the second gate signals. The voltage level of the second driving signal (SGS2, SGS4, ..., etc.) generated by the generator 9046 is greater than a predetermined value TG. Because the second driving signal (SGS2, SGS4, etc.) generated by the second gate signal generator 9046 corresponds to the even-numbered gate lines G2, G4, ..., the even-numbered gate lines G2, G4. The charging condition of .. is close to the charging condition of the odd gate lines G1, G3, .... As such, the vertical line problem of the liquid crystal panel 902 can be improved. In addition, in another embodiment of the present invention, the second gate signal generator 9046 is based on N/2 first drivers corresponding to the odd gate lines G1, G3, ... among the N first driving signals. The signal generates N/2 second driving signals corresponding to the odd gate lines G1, G3, ..., wherein the second driving signals corresponding to the odd gate lines G1, G3, ... (SGS1, SGS3. The voltage level of . . . etc. is greater than the voltage level of the first drive signal (FGS1, FGS3, ..., etc.) corresponding to the odd-numbered gate lines G1, G3, . . . Thus, the charging state of the sub-pixels corresponding to the gate lines of the odd-numbered strips G1, G3, ... is close to the charging state of the sub-pixels corresponding to the even-numbered strips G2, G4, ..., and the vertical line of the liquid crystal panel 902 The problem can be improved.
