用電^m。其中，資料驅動電路1()4係透過多條資料驅動ς 晝素陣列搬，以提供資料訊號。掃描驅動電路咖 係透過^歸描，鶴線UG，啸供翻 U4係電性輕接至晝素陣列1〇2，以提供共用電位V、用電極 在圖1中’資料驅動線108與掃描驅動線11〇共同的 ^皮定AM個子晝素’而四個子晝相可構成晝素陣歹^ 中的-個畫素112。其中，如圖2所示，四個子書 2〇4、2〇6與施之顏色分別依序為綠色⑹、藍[⑻、 jU)與白色（W)(排列成2χ2的矩陣）。在顯示器ι〇〇 被f入資料時，掃描驅動電路1〇6係用來開啟整列（r〇w)的 、二^ (尺平方向卜以讓資料驅動電路104之資料訊號可以 L晝素之電容(未繪示）的一端’電容的另-端則為 用雷二傳來之共用電位。因此，根據資料訊號與共 用電位間^㈣則可用來定義子晝素的極性。 金I Γ目别㊉使用之列反轉（騰^1^011)為例，在圖1之 三列的子畫素被定義㈣性(資料 Π! ?電位），第二、四列的子畫素被定義為負 電麗小於共用電位）。在-畫面時間中，若 各旦素中的子畫素排列為田字型時，第-列中的第-個子晝素m 3 201123133 與第三列中的第一子個畫素的顏色是相同的，但第一列的第一 個子晝素與第二列的第一個子晝素的顏色並不相同。依此類 推’在畫素陣列102中，相鄰晝素中相同顏色之子畫素的極性 將會是相同。亦即’對於同一個顏色而言，以列反轉的技術來 進行驅動時，將使此顏色的驅動方式成為圖框反轉（frame inversion)的驅動方式（也就是同一個顏色在一個圖框中呈現 完全相同的極性’而在下一個圖框中完全改變為另一種極 性）。此種驅動方法將使得晝面產生閃爍的情形。 請參照圖3A，其係繪示習知之顯示器為常態黑色模式時 之灰階示意圖。在圖3A之常暗型（normally black mode)顯 示器中，假設在整個圖框中包括有灰階區塊（受驅動狀態）3〇〇 與黑色區塊（非驅動狀惡）306，第一資料驅動線302通過部 分之灰階區塊300與部分之黑色區塊306，第二資料驅動線3〇4 則僅通過灰階區塊300。 請接著參照圖3B〜3C，其係分別繪示第一資料線之資料 訊號與共用電位之理想狀態示意圖與串擾狀態示意圖。在圖 3B中，資料訊號310 (粗黑實線）係為由第一資料驅動線3〇2 所提供，共用電位308 (細黑實線）為由圖i之共用電極114 所提供。其中，資料訊號310的更新頻率與共用電位308之轉 換頻率預設為相同頻率。而且，在共用電位3〇8中每個子畫素 的時間週期為T ’也就是說，為使能夠達成列反轉之目的，共 用電位308每隔一個時間T，即需提高或降低其電壓位準。^ 圖3B所示，第一資料驅動線302之受驅動狀態的子畫素中， 資料訊號310與共用電位308之間具有第一壓差312 (可視為 反相）。從第一時間點316開始（灰階區塊3〇〇與里色區 306之交界），資料訊號與共用電位3<Λ被二為^目 201123133 而在第二時間點318之後（黑色區塊306與灰階區塊300之交 界），資料訊號310與共用電位308間之壓差就會變回第一壓 差312。但由於資料訊號310之電壓非常大，因此將使得共用 電位308與資料訊號310產生耦合效應，而使得在第一時間點 316與第二時間點318之間的共用電位308因為資料訊號31〇 的轉換而耦合出如標號320所標示的串擾（crosstalk)區（如 圖3C所示）。 請參照圖3D〜3E，其係分別續示圖3A之第二資料線之 φ 資料訊號與共用電位之理想狀態示意圖與串擾狀態示意圖。在 圖3D中’資料訊號324 (粗黑實線）係為由第二資料驅動線 3〇4所提供，共用電位322 (細黑實線）為由圖丨之共用電極 114所提供。如圖3D所示，第二資料驅動線304之受驅動狀 態的子晝素中’資料訊號324與共用電位322之間具有第一壓 差328。因第二資料驅動線304受第一資料驅動線3〇2之資料 訊號324之轉換的影響，因此第二資料驅動線3〇4上與第一資 料驅動線302之黑色區塊306相鄰之子畫素的共用電位322亦 會受到第一資料驅動線302上之資料訊號31〇的大電壓影響而 產生耦合效應。故，如圖3E所示的共用電位322會出現串擾 區，而在串擾區中的共用電322與資料訊號324之間的電位差 異會比原先設計的標準電位差異來得更大。因此，第二資料驅 動線304上之部分子晝素因受黑色區塊遍上之資料訊號31〇 的衫響’被景〉響之第一資料驅動線3〇4上之部分子畫素的亮度 將比原本晝面之亮度更亮。 —” 在習知之技術中’在田字型的四色子畫素矩陣中使用列反 轉進行驅動時，將會造成在同一畫面時間中相同顏色之子畫素 的極性均相同，而使畫面較容易產生閃燦，而且在與非驅動狀 201123133 -、旦素相鄰的欠驅動子晝素的共用電位將被非驅動狀態 之子晝素的資料訊號影響而造成失真。 【發明内容】 本發明的目的就是在提供一種顯示器，其可以解決因圖框 反轉所造成的閃爍問題。 ~本發明的再-目的是提供—種顯示器驅動方法，其可降低 資料訊號與共用電位間之串擾。 _ 本發明提出-種顯示器，此顯示器包括晝素陣列、資料驅 動線、閘極驅動線與共用電極。上述之晝素陣列具有第一畫 $第一畫素與第二畫素。此第一晝素與第二畫素相鄰第— 且素與第三4素相鄰，每—晝素包括多個子畫素，每一子晝素 均代=-對應齡。上叙資料轉線電_接至第—畫素與 第一晝素。上述之閘極驅動線電性耦接至第一畫素與第三晝 素。上述之共用電極電性祕至第-晝素、第二畫素與第三晝 ΐ,,、以提供共用電位至第—晝素、第二畫素與第三晝素。其中， 負^驅動線》別提供資料訊號至第-畫素與第二晝素，以使第 一晝素與第二畫素中代表同樣之對應顏色之子晝素相對於此 用電極而言具有不同極性，且第-晝素與第三畫素中代表同^ 之對應顏色之子晝素相對於制電極而言具有相同極性。 在本發明的較佳實施例t，上述之對應顏色包括紅色、綠 色、藍色與白色。 在本發明的較佳實施例中，上述之每一畫素中的子像素依 照各自代表之對應顏色的排列係為相同。 在本發明的較佳實施例中，上述之資料訊號之頻率為共用 電位之頻率的兩倍。 在本發明的較佳實施例十，當子晝素之一處於受驅動狀態 201123133 時，提供至子畫素之資料訊號與共同電位間具有第一壓差。 在本發明的較佳實施例中’當子晝素之一處於非驅動狀態 時’提供至子畫素之資料訊號與共同電位間具有第二壓差，且 第一壓差大於第二壓差。 在本發明的較佳實施例中，當第一晝素中耦接至資料驅動 線的兩相鄰子畫素依序分別處於受驅動狀態與非驅動狀，離、 時，資料訊號與共用電位間之壓差係於對應兩相鄰子晝素之共 用電位的二分之一期間時由第一壓差轉為第二壓差。 、 在本發明的較佳實施例中，當第一晝素中麵接至資料驅動 線的兩相鄰子畫素依序分別處於非驅動狀態與受驅動狀態 時’資料訊號與共用電位間之壓差係於對應兩相鄰子晝素之共 用電位的二分之一期間時由第二壓差轉為第一壓差。 本發明再提出一種顯示器驅動方法。此顯示器包括由第一 畫素、第二晝素與第三晝素組成之畫素陣列、電性耦接至第一 S·素與第一晝素之資料驅動線、電性輛接至第一晝素與第三畫 素之閘極驅動線以及電性耦接至第一晝素、第二晝素與第三晝 素之共用電極。其中每一晝素包括多個子畫素，每一子畫素代 表一對應顏色。此顯示器驅動方法為分別提供資料訊號至第一 晝素與第二晝素。其次，分別提供共用電位至第一晝素、第二 晝素與第三晝素。接著，使第一畫素與第二晝素中代表同樣之 對應顏色之子畫素相對於共用電極而言具有不同極性。然後， 使第一晝素與第三晝素中代表同樣之對應顏色之子晝素相對 於共用電極而言具有相同極性。 本發明因採用兩線反轉（tw〇 Hne inversi〇n)，因此可以 解决因圖框反轉（frame inversion)所造成的閃蝶問題，並降 低資料訊號與共用電位間之串擾 201123133 為讓本毛明之上述和其他目的、特徵和優點能更明顯易 僅，下文特舉較佳實施例’並配合所附圖式，作詳細說明如下。 【實施方式】Use electricity ^m. The data driving circuit 1 () 4 is driven by a plurality of data-driven 昼 阵列 arrays to provide data signals. The scanning drive circuit is transmitted through the ^, the crane line UG, the whistling U4 series is electrically connected to the halogen array 1〇2 to provide the common potential V, and the electrode is used in FIG. 1 'data drive line 108 and scanning The driving line 11 〇 〇 AM AM AM AM AM 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而As shown in FIG. 2, the four sub-books 2〇4, 2〇6 and the applied colors are respectively green (6), blue [(8), jU) and white (W) (arranged as a matrix of 2χ2). When the display is loaded into the data, the scan driving circuit 1〇6 is used to turn on the entire column (r〇w), and the data signal of the data driving circuit 104 can be used. The other end of the capacitor (not shown) is the common potential transmitted by Ray 2. Therefore, according to the data signal and the common potential ^ (4) can be used to define the polarity of the sub-halogen. For example, if you use the column inversion (Teng ^1^011) as an example, the sub-pixels in the third column of Figure 1 are defined (four) (data Π! ? potential), and the second and fourth columns of sub-pixels are defined. Negative charge is less than the shared potential). In the picture time, if the sub-pixels in each element are arranged in a field type, the color of the first sub-element m 3 201123133 in the first column and the first sub-pixel in the third column is The same, but the first child of the first column is not the same color as the first child of the second column. In the pixel array 102, the polarities of the sub-pixels of the same color in the adjacent pixels will be the same. That is, for the same color, when driving with the column inversion technique, the driving method of this color will be the driving method of frame inversion (that is, the same color is in a frame). The same polarity is present in 'and completely changed to another polarity in the next frame). This driving method will cause the kneading surface to flicker. Please refer to FIG. 3A, which is a schematic diagram showing the gray scale when the conventional display is in the normal black mode. In the normally black mode display of FIG. 3A, it is assumed that a gray-scale block (driven state) 3〇〇 and a black block (non-driving state) 306 are included in the entire frame, the first data. The drive line 302 passes through a portion of the gray scale block 300 and a portion of the black block 306, and the second data drive line 3〇4 passes only the gray scale block 300. Please refer to FIG. 3B to FIG. 3C respectively, which are schematic diagrams showing the ideal state of the data signal and the common potential of the first data line and the crosstalk state diagram. In Fig. 3B, the data signal 310 (thick black solid line) is provided by the first data driving line 3〇2, and the common potential 308 (thin black solid line) is provided by the common electrode 114 of Fig. i. The update frequency of the data signal 310 and the conversion frequency of the common potential 308 are preset to the same frequency. Moreover, the time period of each sub-pixel in the common potential 3 〇 8 is T 'that is, for the purpose of enabling column inversion, the common potential 308 is raised or lowered every other time T. quasi. As shown in FIG. 3B, in the sub-pixel of the driven state of the first data driving line 302, the data signal 310 and the common potential 308 have a first voltage difference 312 (which can be regarded as an inversion). Starting from the first time point 316 (the boundary between the gray level block 3〇〇 and the inner color area 306), the data signal and the common potential 3<Λ are the second time 201123133 and after the second time point 318 (black block) Between the intersection of the 306 and the gray level block 300, the voltage difference between the data signal 310 and the common potential 308 changes back to the first voltage difference 312. However, since the voltage of the data signal 310 is very large, the common potential 308 and the data signal 310 will be coupled together, so that the common potential 308 between the first time point 316 and the second time point 318 is due to the data signal 31. The conversion is coupled to the crosstalk region as indicated by reference numeral 320 (as shown in Figure 3C). Please refer to FIG. 3D to FIG. 3E , which are respectively a schematic diagram showing an ideal state of the φ data signal and the common potential of the second data line of FIG. 3A and a schematic diagram of the crosstalk state. In Fig. 3D, the 'data signal 324 (thick black solid line) is provided by the second data driving line 3〇4, and the common potential 322 (thin black solid line) is provided by the common electrode 114 of the figure. As shown in FIG. 3D, the data signal 324 of the driven state of the second data driving line 304 has a first voltage difference 328 between the data signal 324 and the common potential 322. Because the second data driving line 304 is affected by the conversion of the data signal 324 of the first data driving line 3〇2, the second data driving line 3〇4 is adjacent to the black block 306 of the first data driving line 302. The common potential 322 of the pixel is also affected by the large voltage of the data signal 31〇 on the first data driving line 302 to cause a coupling effect. Therefore, the crosstalk region appears in the common potential 322 as shown in Fig. 3E, and the potential difference between the shared power 322 and the data signal 324 in the crosstalk region is larger than the difference in the standard potential of the original design. Therefore, part of the sub-pixels on the second data driving line 304 are subjected to the brightness of the partial sub-pixels on the first data driving line 3〇4 of the first data driving line 3' by the data signal 31〇 of the black block. It will be brighter than the original one. —” In the conventional technique, when column inversion is used in the four-color sub-pixel matrix of the field type, the polarity of the sub-pixels of the same color is the same in the same picture time, and the picture is compared. It is easy to produce flashing, and the common potential of the under-driven sub-single adjacent to the non-driving state 201123133-, the dansin is affected by the data signal of the sub-segment of the non-driving state, causing distortion. [Description of the Invention] The object is to provide a display that can solve the flicker problem caused by frame inversion. ~ The re-purpose of the present invention is to provide a display driving method which can reduce crosstalk between a data signal and a common potential. The invention provides a display comprising a pixel array, a data driving line, a gate driving line and a common electrode. The above pixel array has a first picture $1 pixel and a second picture element. Adjacent to the second pixel - and the prime is adjacent to the third four elements, each of the alizae includes a plurality of sub-pixels, each sub-genogen is == corresponding age. First-pixel The first gate element is electrically coupled to the first pixel and the third pixel. The shared electrode is electrically secreted to the first pixel, the second pixel, and the third pixel. To provide a common potential to the first element, the second pixel and the third element. Among them, the negative driving line does not provide a data signal to the first pixel and the second element, so that the first element and The sub-crystals representing the same corresponding color in the second pixel have different polarities with respect to the electrode for use, and the dioxins and the sub-crystals representing the corresponding color of the third pixel are relative to the electrode. In the preferred embodiment t of the present invention, the corresponding colors include red, green, blue, and white. In a preferred embodiment of the present invention, the sub-pixels in each of the above pixels are in accordance with the respective The arrangement of the corresponding colors is the same. In a preferred embodiment of the invention, the frequency of the above-mentioned data signal is twice the frequency of the common potential. In the preferred embodiment of the present invention, when Provided to the sub-pixel when it is in the driven state 201123133 There is a first voltage difference between the data signal and the common potential. In a preferred embodiment of the invention, 'when one of the sub-singers is in a non-driven state, the data signal supplied to the sub-pixel has a second voltage between the common potential and the common potential. Poor, and the first voltage difference is greater than the second voltage difference. In a preferred embodiment of the present invention, two adjacent sub-pixels coupled to the data driving line in the first pixel are sequentially driven and respectively In the non-driving state, the voltage difference between the data signal and the common potential is changed from the first differential pressure to the second differential pressure when the two-period of the common potential of the two adjacent sub-elements are corresponding to each other. In a preferred embodiment of the present invention, when two adjacent sub-pixels of the first pixel connected to the data driving line are sequentially in a non-driving state and a driven state, respectively, a voltage difference between the data signal and the common potential It is converted from the second differential pressure to the first differential pressure during a period corresponding to one half of the common potential of the two adjacent sub-halogens. The invention further proposes a display driving method. The display includes a pixel array composed of a first pixel, a second halogen and a third halogen, a data driving line electrically coupled to the first S and the first pixel, and an electrical device connected to the first a gate driving line of the first pixel and the third pixel and a common electrode electrically coupled to the first halogen, the second halogen and the third halogen. Each of the elements includes a plurality of sub-pixels, each of which represents a corresponding color. The display driving method is to provide data signals to the first and second pixels, respectively. Secondly, a common potential is supplied to the first halogen, the second halogen and the third halogen, respectively. Next, the sub-pixels representing the same corresponding color in the first pixel and the second pixel have different polarities with respect to the common electrode. Then, the first halogen and the third halogen represent the same corresponding color of the sub-halogen with the same polarity with respect to the common electrode. The invention adopts two-line inversion (tw〇Hne inversi〇n), so that the problem of the butterfly caused by the frame inversion can be solved, and the crosstalk between the data signal and the common potential is reduced.

In the present embodiment, three adjacent elements 430, 432 and 434 are taken as an example for illustration. The sub-studies 430a and 430b in the pixel 430 and the sub-studies 434a and 434b in the pixels 434 receive data signals from the same data driving line 408. Similarly, the sub-pixels 43〇c, 430d in the 430, and the sub-studies 434c and 434d in the alizarin 434 receive data signals from the same data driving line 408. The data elements 432a and 432b of the pixel 432 receive the data signal from the data driving line 408, and the data elements 432c and 432d of the pixel 432 receive the data signal from the same data driving line 408. The sub-pixels 432a and 432c of the halogen elements 430a and 430c and the halogen elements 432 receive the gate signals from the same gate driving line 410. Similarly, the sub-pixels in the alizarin 430 • 43〇b, 43〇d and the sub-forms 432b and 432d of the pixel 432 receive the gate signal from the same gate driving line 410. In addition, the sub-pixels 434a and 434c in the pixel 434 receive the gate signal from the same gate driving line 410, and the sub-pixels 434b and 434d in the pixel 434 receive the gate signal from the same gate driving line 410. In Fig. 4B, when the data signal and the common potential are supplied to the halogens 430 and 434, the sub-element of the corresponding color which is the same as the representative of the pixels 430 and 434 has different polarities with respect to the common electrode 414. Further, when the data signal and the common potential are supplied to the halogens 430 and 432, the sub-pixels representing the same corresponding colors in the pixels 430 and 432 have the same 201123133 polarity with respect to the common electrode 414. In the preferred embodiment of the invention, the color arrangement of the pixels 430, 432 and 434 may be different. Taking FIG. 5 as an example, the color arrangement of the sub-pixels 502, 504, 506, and 508 in the alizarin 430 may be, for example, green (G), blue (b), red (R), and white (W) 'pixels 432. The color arrangement of the scorpion 502, 504, 506, 508 can be, for example, green (g), red (R), blue (B), and white (W), and the morpheme 502, 504, 506 in the 434. The color arrangement of 508 may be, for example, green (G), blue (B), and white (w) φ red (R). Next, please refer to FIG. 6, which is a flow chart showing the steps of a display driving method according to an embodiment of the invention. Referring to FIG. 4A and FIG. 6 simultaneously, in the display 400, when the pupil plane is to be displayed in the pixel array 402, the gate signal is sequentially supplied to each column by the gate driving line 406 in one screen time (horizontal direction). Each sub-pixel of the ) to open the sub-pixel. After the sub-cells of one column are turned on, the data driving circuit 404 transmits the data signal to the first sub-element of each line (vertical) (step S602). In this embodiment, when the data signal is transmitted to the first sub-picture of each row, the common electrode 414 transmits the common potential to one end of the connection of the capacitors of each sub-single (step _ 4). In this embodiment, the steps S602 and 604 may be sequential or simultaneous, and are not limited to the description in this embodiment. In a preferred embodiment of the present invention, after each sub-element of the first column is written with the data signal, the gate driving circuit 406 turns off the sub-pixel of the first column and turns on the sub-pixel of the second column. So that the data driving circuit 404 can write to each sub-cell of the second column. Then, when the data driving circuit 404 and the common electrode 414 respectively provide the data 201123133 conjugate potential to the elements 430 and 432 of FIG. 4B, the pixel 430 has the same corresponding color of the sub-pixel relative to the electrode. The words have the same polarity (step S606). Then, when the data driving circuit 404 and the common electrode 414 respectively raise potentials to the cells 430 and 434 of FIG. 4B, the sub-stimuli of the corresponding color of the halogen element 430 have different polarities with respect to the common electrode 414. (Step S608). And 7B, which respectively illustrate the ideal state of the data signal and the common potential of the sound, the Lit_data line according to an embodiment of the present invention. In this embodiment, the switching frequency of the common potential can be adjusted to be half the update frequency of the data signal in accordance with the display driver described above. If you are familiar with the art, you can easily know that if a single element of the ΐ子昼素 matrix is constructed, the conversion frequency of the common potential can be adjusted; 22: t is one-half of the update frequency. In the preferred embodiment of the present invention, the present invention utilizes two line inversion, and therefore, compared to Figs. 3A and 3B, the common potential 7〇8 is every two = lower voltage level. That is to say, the common potential 7〇8 needs to be voltage-converted after _2^^^, so that the power consumption can be reduced. In Fig. 7A, the data signal 710 (thick black solid line) is provided by the -B, the drive line 3.2 of Fig. 3A, and the common potential (the thin black solid line) is provided by a = electrode 414. The first data driving line 302 of the ®3A is two degrees: in the first sub-pixel, the data signal 710 and the common potential 708 have a voltage difference of 712 ^ from the first time point 716 (gray block 3〇〇) And the black start 'data signal 710 and the shared potential 708 are tuned ί ί can have a second pressure difference) β where, as familiar with the poor, the readable and easy to know 'the second climax can approach 0 or equal to 〇 The 201123133 depends on the design time requirement. At the second time point 718 (the boundary between the black block 306 and the gray level block 300), the voltage difference between the data signal 710 and the common potential 708 changes from the second differential pressure. It is the first voltage difference 712. As shown in FIG. 7B, although the common potential 708 and the data signal 710 still have a coupling effect, the waveform of the common potential 708 is between the first time point 716 and the second time point 718 because of the data. The conversion of the signal 7丨〇 couples the crosstalk region as indicated by reference numeral 720. In this example, the number of crosstalk regions can be reduced in this embodiment. Referring to FIG. 7C to FIG. 7D, FIG. 7 is a schematic diagram showing the ideal state of the data signal and the common potential of the second data line of FIG. 3A according to an embodiment of the present invention. A schematic diagram of the crosstalk state. In Figure 7C, 'data signal 724 (thick black solid line) is provided by second data drive line 304, and common potential 722 (thick black solid line) is provided by common electrode 414 of FIG. As shown in FIG. 7C, in the driven state of the second data driving line 304, the data signal 724 and the common potential 722 have a first voltage difference 728. Since the second data driving line 304 is driven by the first data. The conversion of the data signal 324 of the line 302 is affected. Therefore, the common potential 722 of the sub-element adjacent to the black block 3〇6 of the first data driving line 3〇2 on the second data driving line 304 is still subjected to the data signal 724. The large voltage affects the coupling effect and causes the common potential 722 between the first time point 716 and the second time point 718 to be coupled out of the crosstalk region as indicated by reference numeral 72 by the conversion of the data signal 710. But in In this embodiment, the present embodiment reduces the number of crosstalk regions. In summary, in the display and display driving method of the present invention, since two line inversi〇n is used, it is possible to solve the problem due to frame inversion. The problem of flicker caused by inversion. In addition, the present invention can also reduce the number of reduced crosstalk regions between data number 1 and the common potential, and achieve the effect of reducing power consumption [S} 12 201123133.
