201028982 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種極性反轉驅動方法，特別是關於一 種整合性極性反轉之顯示裝置、顯示模組及其顯示驅動方 法0 【先前技術】 由於液晶顯示裝置具有薄型化、輕量化、低耗電量、 無輕射污染，且能與半導體製程技術相容等優點，如今已 廣泛運用於各式電子產品上，故對其技術及功能要求也越 來越高。 液晶分子有一種特性’就是無法操作在某一個固定電 壓不變，時間久了，即使電壓取消掉，液晶分子仍會因為 其特性被破壞而無法再因應電場的變化來轉動，以形成不 同的灰階’而造成面板上有殘留影像。所以每隔一段時 間，就必須改變電壓準位，以避免液晶分子的特性遭到破 壞。 為了避免上述情況，目前在顯示面板中係應用了圖框 極性反轉（Frame Inversion，FI )、線極性反轉（Line Inversion, LI)和點極性反轉（Dot Inversion，DI)的驅動 方式來驅動顯示面板。 線極性反轉又可以分為欄極性反轉（Column Inversion， CI)及列極性反轉（R〇w Inversion, RI)，雖然有這麼多 種的極性反轉，但它們都具有一個共通點，就是在下一次 201028982 更換晝面資料（Frame)的時候會改變極性。以60Hz的更 新頻率來說，在時間上約每16ms更改一次畫面的極性。 也就是說，對於同一點顯示畫素（Pixel)而言，它的極性 是每間隔16mS就會變換一次，並且隨著時間不停地變 換。而相鄰的點是否擁有相同的極性，那可就依照不同的 極性反轉來決定。 以下將簡單說明各種極性反轉。首先是圖框極性反轉 (FI)，其整個畫面上所有相鄰的畫素，都是擁有相同的 • 極性。 線極性反轉（LI)，則在晝面上的同一資料線是同一 極性，或者是在晝面上同一掃描線是同一極性。 點極性反轉（DI)，則是晝面上的每個點與自己上下 左右相鄰的四個點，是不一樣的極性。 上述的三種極性反轉的效能比較，將敘述如下：圖框 極性反轉最省電，但顯示品質最差。點極性反轉最耗電， ©但相對的顯示品質最好。線性極性反轉的效能處於圖框極 性反轉與點極性反轉的兩者中間。 現行的驅動方式皆只能在一個顯示裝置中使用一種 極性反轉來驅動顯示面板，而只能在節省電力或加強顯示 品質中作一取捨。 因此，如何提供一種顯示裝置、顯示模組及其顯示驅 .. 動方法，能夠取其各極性反轉的優點，並根據顯示晝面的 - 不同而使用不同極性反轉，將其整合運用在顯示面板上， 正是當前的重要課題之一。 201028982 【發明内容】 有鑑於上述課題，本發明之目的在於提供一種能夠提 升顯示品質和節省電能之顯示裝置、顯示模組及其顯示驅 動方法。 為達上述目的，本發明提供一種顯示裝置，其具有一 顯示模組，而顯示模組包含一顯示面板、一極性反轉控制 單元及一共同電壓輸出單元。 極性反轉控制單元，控制顯示面板操作於各種極性反 ® 轉和各種極性反轉組合。 . 共同電壓輸出單元，分別與顯示面板及極性反轉控制 單元電性連接，且共同電壓輸出單元具有一共同電壓產生 器及一多工器。 為達上述目的，本發明提供一種顯示模組，係包含一 顯示面板、一極性反轉控制單元及一共同電壓輸出單元。 極性反轉控制單元，控制顯示面板操作於各種極性反 Φ 轉和各種極性反轉組合。 共同電壓輸出單元，分別與顯示面板及極性反轉控制 單元電性連接，且共同電壓輸出單元具有一共同電壓產生 器及一多工器。 為達上述目的，本發明提供一種顯示模組的顯示驅動 方法，其中顯示模組包含一顯示面板、一極性反轉控制單 - 元及一共同電壓輸出單元。顯示驅動方法包含下列步驟： - 步驟一：於第一時間，由極性反轉控制單元以一第一 極性反轉驅動顯示面板，並由共同電壓輸出單元輸出一第 201028982 一共同電壓至顯示面板； 步驟一.於第二時間，由極性反轉控制單元以一第二 極性反轉驅動顯示面板，並由共同電壓輪出單元 二共同電壓至顯示面板。 為達上述目的，本發明提供—種顯示裝置的顯示驅動 法’其中顯示裝置包含一顯示模組，而顯示模組包含一 貝:面板、一極性反轉控制單元及一共同電壓輪出單元。 . 顯示驅動方法包含下列步驟： 步驟一 ··於第一時間’由極性反轉控制單元以一第一 極性反轉驅動顯示面板，並由共同電壓輸出單元輸出一第 ~共同電壓至顯示面板； 步驟二：於第二時間，由極性反轉控制單元以一第二 極性反轉驅動顯示面板，並由共同電壓輸出單元輸出一第 二共同電壓至顯示面板。 —承上所述，因依本發明之顯示裝置、顯示模組及其顯 © :驅動方法係在同—顯示裝置中以複數極性反轉驅動顯 不面板’配合不同的顯示畫面或使用需求，而可選擇以不 同的極性反轉來驅動顯示面板，以取其各極性反轉的優點 以提升顯示品質及節省電能。 【實施方式】 —u下將參照相關圖式，說明依本發明較佳實施例之顯 示驅動方法、顯示模組及顯示裝置。 請參照圖1所示，本發明較佳實施例之顯示裝置1〇〇 201028982 具有一顯示模組110，而顯示模組110包含一顯示面板 120、一極性反轉控制單元130及一共同電壓輸出單元140。 極性反轉控制單元130，輸出複數極性控制訊號SP、 一資料訊號及一切換控制訊號Sw，並控制顯示面板120， 使顯示面板120操作於複數極性反轉之其中之一。 在本實施例中，資料訊號係為顯示面板120中複數晝 素所欲顯示的灰階訊號，另外極性反轉例如但不限於點極 性反轉、線極性反轉、兩線（two line )極性反轉或圖框極 • 性反轉。其中，線極性反轉又可分為欄極性反轉及列極性 反轉。 另外，在本實施例中，極性反轉控制單元130係可設 置於時序控制器（Timing Controller, TCON)中，當然亦 可為單獨的晶片。 共同電壓輸出單元140分別與顯示面板120及極性反 轉控制單元130電性連接。共同電壓輸出單元140具有相 ^ 互電性連接之一共同電壓產生器141及一多工器142。 譬 其中，共同電壓產生器141係接收極性控制訊號SP， 並據以產生複數共同電壓 VcOMl' VC〇M2及 VC〇M3 ° 在此， 不同的共同電壓係對應於不同的極性反轉所需要的共同 電壓。 本實施例中，資料訊號可包含一第一資料訊號D i及 • 一第二資料訊號D2，其中第一資料訊號Di係與共同電壓 Vc〇Ml 相互配合，第二資料訊號D2係與共同電壓V COM2才目 互配合以驅動顯示面板120。 201028982 M2係接收切換控制職輸出共同 性反轉、線 =二_、VC_及VC_之其中之-至顯示面板12〇, 資料訊號使得顯示面板120操作於點極 極丨生反轉及圖框極性反轉。 · * ⑽2照圖2所示’本發明較佳實施例之一種顯示裝置 和驅動方法，係包含步驟S1⑽和步驟s2〇〇。請 同夸 > 照圖1和圖2，並配合圖3所示。 以一7 S1〇o係於第-時間tl，由極性反轉控制單元13〇 〜極性反轉驅動顯示面板12〇,並由共同電壓輸出 早輪出-第一共同電壓Vc〇M1至顯示面板120。 以一笫驟S200係於第二時間t2’由極性反轉控制單元130 时元〜極性反轉驅動顯示面板120，並由共同電壓輸出 〇輪出一第二共同電壓vCOM2至顯示面板120。 其中，第一時間與第二時間t2，係可為相鄰或不相 之時間，於此並不加以限制。 ❹ 一 本實施例中，第一極性反轉係可為線極性反轉，而第 第極座反轉係可為圖框極性反轉。當然，第一極性反轉及 極I·生反轉亦可分別為圖框極性反轉、線極性反轉或點 極性反轉之其中之二。 、& 5兒明的是’在此係以兩種極性反轉為例說明，然其 f非為限制性。意即，顯示裝置100可依據其實際顯示所 而而可有更多的極性反轉之選擇。 一 另外’由於顯示模組及其顯示驅動方法已於上述之顯 厂、襄置及其顯示驅動方法中一併敘述，故於此不再加以贅 201028982 述。 綜上所述，極性反轉控制單元以複數極性反轉驅動顯 示面板，共同電壓輸出單元依據各極性反轉而輸出相對應 之共同電壓至顯示面板。此種複數極性反轉的顯示驅動方 法，可以避免單一極性反轉所產生的問題，進而可在提升 顯示裝置之顯示品質的同時，也能夠達到節省電能的目 的。 以上所述僅為舉例性，而非為限制性者。任何未脫離 • 本發明之精神與範疇，而對其進行之等效修改或變更，均 應包含於後附之申請專利範圍中。 【圖式簡單說明】 圖1為顯示依據本發明較佳實施例之顯示裝置之一方 塊圖； 圖2為顯示依據本發明較佳實施例之顯示裝置之顯示 ©驅動方法之一流程圖；以及 圖3為顯示依據本發明較佳實施例之顯示裝置之顯示 驅動方法之資料訊號及共同電壓之一波形示意圖。 【主要元件符號說明】 100 :顯示裝置 . 110 :顯示模組 120 :顯示面板 130 :極性反轉控制單元 201028982201028982 VI. Description of the Invention: [Technical Field] The present invention relates to a polarity inversion driving method, and more particularly to an integrated polarity inversion display device, display module and display driving method thereof. [Prior Art] Since the liquid crystal display device has the advantages of thinness, light weight, low power consumption, no light pollution, and compatibility with semiconductor process technology, it has been widely used in various electronic products, so its technical and functional requirements. It is getting higher and higher. Liquid crystal molecules have a characteristic 'that is impossible to operate at a fixed voltage. For a long time, even if the voltage is cancelled, the liquid crystal molecules will not be able to rotate according to the change of the electric field because of their characteristics, so as to form different grays. Stage ' has a residual image on the panel. Therefore, at regular intervals, the voltage level must be changed to avoid damage to the characteristics of the liquid crystal molecules. In order to avoid the above situation, the frame inversion (FI), line inversion (LI) and dot inversion (DI) driving modes are currently applied in the display panel. Drive the display panel. Line polarity reversal can be divided into Column Inversion (CI) and Column Inversion (RI). Although there are so many polarity reversals, they all have a common point. The polarity will change when the next 201028982 is replaced. At the 60 Hz update frequency, the polarity of the picture is changed approximately every 16 ms in time. That is to say, for the same point display pixel (Pixel), its polarity is changed every 16mS interval, and it is constantly changing over time. Whether adjacent points have the same polarity can be determined by different polarity inversions. The various polarity inversions will be briefly explained below. The first is the frame polarity inversion (FI), where all adjacent pixels on the entire screen have the same • polarity. Inverted line polarity (LI), the same data line on the top surface is the same polarity, or the same scan line on the top surface is the same polarity. Point polarity inversion (DI) is the difference between each point on the face and four points adjacent to each other. The comparison of the above three polarity reversal effects will be described as follows: The polarity reversal of the frame is the most energy efficient, but the display quality is the worst. Point polarity reversal consumes the most power, but the relative display quality is the best. The performance of linear polarity inversion is intermediate between the polar inversion of the frame and the inversion of the polarity of the points. The current driving method can only use one polarity inversion to drive the display panel in one display device, and can only make a trade-off between saving power or enhancing display quality. Therefore, how to provide a display device, a display module, and a display driving method thereof can take the advantages of reverse polarity of each polarity, and use different polarity inversion according to different display surfaces, and integrate them in On the display panel, it is one of the current important topics.
