Description

具有整合式觸控螢幕的顯示裝置及其驅動方法
本發明涉及一種顯示裝置,尤其涉及一種具有整合式觸控螢幕的顯示裝置。
觸控螢幕為一種包括在影像顯示裝置如液晶顯示器(LCDs)、場發射顯示器(FEDs)、電漿顯示面板(PDPs)、電致發光顯示器(ELDs)、以及電泳顯示器(EPDs)中且允許使用者藉由施加壓力(即,按壓或觸摸)於觸控螢幕的觸控感應器來輸入資訊的輸入裝置。具有整合式觸控螢幕的顯示裝置如智慧手機以及平板電腦(PCs)的需求不斷增加。
下面將參考第1圖描述先前技術之具有內嵌式整合式觸控螢幕的顯示裝置。尤其是,第1圖為說明先前技術之具有內嵌式的整合式自電容觸控螢幕的顯示裝置的示意圖。
如圖所示,先前技術中的顯示裝置包括:面板10,具有複數個內建電極12;顯示驅動器IC(DD-IC)20,連接至外部系統並且控制面板10內部的複數個資料線13;以及觸控IC 30,用於驅動面板10內部的該等電極12。此外,交替地以顯示驅動模式和觸控驅動模式來驅動面板10,從而執行觸控功能和顯示功能。
當面板10的驅動模式為顯示驅動模式時,該等電極12經由連接線23接收共用電壓,以作為用於顯示驅動的複數個共用電極,並且該等資料線13接收自顯示驅動器IC 20的浮動電壓或接地電壓以驅動液晶顯示裝置。
此外,當面板10的驅動模式為觸控驅動模式時,該等電極12經由連接線23接收觸控掃描訊號,以作為複數個觸控電極。如第1圖所示,連接線23連接至該等電極12。
因此,在先前技術中的顯示裝置中,在觸控電極與資料線之間產生初始電容,並且該初始電容越高,觸控感應越低。原因如下。
觸控感應相當於訊雜比(SNR)的大小,其是經由將一訊號(不執行觸控時產生的)與一訊號(執行觸控時產生的)的平均值除以不執行觸控時產生的雜訊的最大值而得到的數值。因此,雜訊越大,SNR的尺寸就越小,因此初始電容越高,觸控感應越低。此外,雜訊值為初始電容值。
下面將參考第2圖詳細描述如上所述之降低觸控感應的初始電容。尤其是,第2圖為第1圖A部分的放大示意圖,第1圖為說明先前技術的顯示裝置。
如第2圖所示,2.85pF的初始電容形成於電極12之間,1.6pF的初始電容形成於資料線13之間。此外,98.5pF的初始電容形成於電極12與資料線13之間,其中資料線13形成為不與電極12重疊,以及25.3pF的初始電容形成於電極12與資料線13之間,其中資料線13形成以與電極12的底部重疊。
如第2圖所示,形成在電極12與資料線13之間的初始電容相對地大於形成在電極12之間的初始電容或者形成在資料線13之間的初始電容。因此,與形成在電極12之間的初始電容或者形成在資料線13之間的初始電容相比較,形成在電極12與資料線13之間的初始電容產生相對較大的雜訊。因此,觸控感應降低。
因此,即使在觸控驅動模式中浮動電壓或接地電壓施加於資料線,當浮動電壓在觸控驅動模式中施加於資料線時可能出現觸控失靈,並且當接地電壓在觸控驅動模式中施加於資料線時初始電容增加,從而導致雜訊增加。此外,觸控感應和觸控的準確性由於形成在電極與資料線之間的初始電容而降低。
因此,本發明的一個目的是提供一種具有整合式觸控螢幕的顯示裝置及其驅動方法,其基本上可以避免由於先前技術的侷限和不足導致的一個或複數個問題。
本發明的另一目的是提供一種具有整合式觸控螢幕的顯示裝置,用於最小化自電容式觸控螢幕中由於在資料線與電極之間產生的初始電容而導致的觸控感應的降低。
為了獲得這些和其他優點並根據本發明的目的,如這裡具體而廣泛地描述,在一方面,本發明提供一種具有整合式觸控螢幕的顯示裝置,該顯示裝置具有一顯示面板,該顯示面板包括被劃分為複數個區塊組的複數個電極、以及複數個資料線;一顯示驅動器IC,被配置以當該面板的驅動模式為一顯示驅動模式時施加一共用電壓於該等電極,並且當該面板的驅動模式為一觸控驅動模式時依序地施加一觸控掃描訊號於每一個區塊組,並且當該觸控掃描訊號施加於一對應的區塊組時將一資料訊號施加於與該對應區塊組關聯的該等資料線;以及一觸控IC,被配置以產生該觸控掃描訊號並且將該觸控掃描訊號施加於該顯示驅動器IC。
在另一方面,本發明提供一種控制具有整合式觸控螢幕的顯示裝置的方法,該方法包括:將包括在該顯示裝置的一顯示面板中的複數個電極劃分為複數個區塊組以及劃分複數個資料線;當該面板的驅動模式為一顯示驅動模式時經由該顯示裝置的一顯示驅動器IC將一共用電壓施加於該等電極;當該面板的驅動模式為一觸控驅動模式時經由該顯示驅動器IC依序地施加一觸控掃描訊號於每一區塊組,並且當該觸控掃描訊號施加於一對應區塊組時施加一資料訊號於與該對應區塊組關聯的該等資料線;以及經由該顯示裝置的一觸控IC產生該觸控掃描訊號並且將該觸控掃描訊號施加於該顯示驅動器IC。

現在參考所附圖式對本發明的示例性實施例作出詳細說明。無論如何,在所附圖式中使用的相同附圖標記用於表示相同或相似的部件。
在根據本發明一實施例之具有整合式觸控螢幕的顯示裝置中,複數個電極被劃分為n組,並且觸控掃描訊號依序地施加於該n組。為方便起見,下面的描述假定該等電極被劃分為3組。然而,本發明不限於將該等電極劃分為3組,該等電極可以被劃分為4組或更多組。此外,形成用於連接觸控驅動器和複數個電極的連接線以在資料線和該等電極之間重疊,並且該連接線連接至觸控驅動器和面板的該等電極以施加自觸控驅動器施加的複數個訊號於各自的電極。
更具體而言,第3圖為說明根據本發明實施例之具有整合式觸控螢幕的顯示裝置的方塊圖。如第3圖所示,該顯示裝置包括面板100,具有劃分為複數個區塊組110的複數個電極120、以及複數個資料線130,其中一偽資料線設置於各自的該等區塊組110之間的間隔中,並且在該等區塊組110的每一組(111,112,113)中都具有相同數量的該等電極120。
此外,該顯示裝置還包括顯示驅動器IC 200,用於當面板100的驅動模式為顯示驅動模式時施加共用電壓於該等電極120,當面板100的驅動模式為觸控驅動模式時施加觸控掃描訊號於每一組,並且施加直流(DC)電壓於該等資料線130;以及觸控IC 300,用於產生並且施加觸控掃描訊號於顯示驅動器IC 200。
此外,面板100可以包括形成在兩基板之間的液晶層。在面板100中,複數個資料線130與複數個閘極線彼此相交,並且複數個像素 由於在該等資料線130與該等閘極線之間的交錯而以矩陣形式排列,從而定義複數個像素區域。此外,每一個資料線130施加資料訊號於像素以驅動液晶面板,並且可以形成於該等電極120之下。
此外,該等組110為複數個區塊組。該等區塊組110有效地施加資料訊號僅於形成在接收觸控掃描訊號的一組之下的資料線。
因此,對於顯示驅動模式而言,每一個電極120接收自顯示驅動器IC 200的共用電壓以作為共用電極。對於觸控驅動模式而言,每一個電極120作為觸控電極,用於伴隨自觸控IC 300施加的觸控掃描訊號來感應觸控位置。此外,共用電壓和觸控掃描訊號經由連接線230施加於各自的電極。
此外,即使說明連接線230為經由面板100的兩側連接至該等電極120,連接線230實際上與資料線130重疊。換言之,在電極120與資料線130之間,連接線230與資料線130重疊,並且連接至該等電極120。
此外,顯示驅動器IC 200包括:觸控驅動器210,用於將共用電壓施加於電極120或者依組施加觸控掃描訊號;以及顯示驅動器220,用於施加DC電壓於資料線130。
更具體而言,顯示驅動器IC 200包括觸控驅動器210,用於當面板100的驅動模式為顯示驅動模式時將由包括在顯示驅動器IC 200中的共用電壓產生器產生的共用電壓施加於電極120,並且當面板100的驅動模式為觸控驅動模式時將電極120劃分為3組,以依地施加觸控掃描訊號於該3組。此外,顯示驅動器220施加DC電壓於形成在接收觸控掃描訊號的3組的任意一組之下的資料線130。
例如,如第3圖所示,當用於感測觸控位置的觸控掃描訊號自觸控驅動器210經由連接線230施加於第一組111時,DC電壓自顯示驅動器220施加於形成在包括在第一組111中的電極之下的料線131。當觸控掃描訊號施加於第二組112時,DC電壓施加於形成在包括在第二組112中的電極之下的資料線132。類似地,當觸控掃描訊號施加於第三組113時,DC電壓施加於形成在包括在第三組113中的電極之下的資料線133。
因此,DC電壓施加於形成在接收觸控掃描訊號的一組之下的資料線,其降低了在接收觸控掃描訊號的一組中的電極與形成在包括在該組中的電極之下的資料線之間形成的初始電容,從而防止觸控感應的降低。
這是因為電位差由於向包括在該組中的電極施加的驅動電壓而產生在包括在接收觸控掃描訊號的一組中的電極與資料線之間,這增加了用於降低觸控感應的初始電容。然而,經由將DC電壓施加於資料線而最小化電極與資料線之間的電位差,從而導致初始電容的降低。
觸控IC 300經由包括在顯示驅動器IC 200中的觸控驅動器210而將觸控掃描訊號施加於該等組110,然後感測電極的電容的變化,以確定電極是否被觸控。
現在參考第3圖詳細描述根據本發明實施例之具有整合式觸控螢幕的顯示裝置的驅動方法。在根據本實施例之具有整合式觸控螢幕的顯示裝置中,時間上地被劃分為顯示驅動和觸控驅動並且根據面板100的驅動模式來執行,並且顯示驅動器IC 200產生同步訊號以區分顯示驅動模式和觸控驅動模式。
當面板100的驅動模式為顯示驅動模式時,由包括在顯示驅動器IC 200中的共用電壓產生器產生的共用電壓同時施加於電極120,並且在顯示驅動器IC 200中產生的DC電壓或者自外部施加於顯示驅動器IC 200的DC電壓經由顯示驅動器220施加於資料線130。
隨後,電極120經由連接線230接收自顯示驅動器IC 200的共用電壓,以作為面板100的顯示驅動的電極,並且複數個像素經由資料線130接收用於驅動其數位邏輯的DC電壓以作為用於顯示驅動的像素。
然而,當面板100的驅動模式為觸控驅動模式時,用於在觸控IC 300中感測觸控而產生之3個劃分的觸控掃描訊號施加於觸控驅動器210,並且在顯示驅動器IC 200中產生的DC電壓或者自外部施加於顯示驅動器IC 200的DC電壓施加於顯示驅動器220。
隨後,施加於觸控驅動器210之3個劃分的觸控掃描訊號經由連接線230施加於形成在面板100中的各自的三組110。例如,在該3個劃分的觸控掃描訊號中,第一觸控掃描訊號經由連接線230施加於第一 組111,第二觸控掃描訊號施加於第二組112,以及第三觸控掃描訊號施加於第三組113。這裡,第一至第三觸控掃描訊號的每一個依序地施加於包括在對應組中的電極,其中每一組中的複數個電極連接至連接線230。
同時,DC電壓自顯示驅動器220依序地施加於形成在包括在接收面板100中的觸控掃描訊號的一組中的電極之下的資料線。例如,當觸控掃描訊號自觸控驅動器210施加於第一組111時,DC電壓自顯示驅動器220施加於形成在包括在第一組111中的電極之下的資料線131。當觸控掃描訊號為自觸控驅動器210施加於第二組112時,DC電壓施加於形成在包括在第二組112中的電極之下的資料線132。當觸控掃描訊號為自觸控驅動器210施加於第三組113時,DC電壓施加於形成在包括在第三組113中的電極之下的資料線133。
隨後,包括在該等組110中的電極120作為用於觸控驅動的電極,其經由連接線230接收自觸控驅動器210的觸控掃描訊號以檢測使用者的觸控位置,並且傳送觸控位置至觸控IC 300。
在本發明的實施例中,形成在接收觸控掃描訊號的該組之下的複數個資料線接收DC電壓,並且降低在一組(接收觸控掃描訊號的)中的電極與形成在該組之下的資料線之間形成的初始電容,從而防止觸控感應的降低。
在本發明的另一實施例中,下面將再次參考第3圖詳細描述一種降低在接收觸控掃描訊號的一組中的電極與形成在該組之下的資料線之間產生的初始電容的方法。
根據本發明另一實施例之具有整合式觸控螢幕的顯示裝置包括面板100,該面板100具有劃分為複數個區塊組110的複數個電極120、以及資料線130。此外,當面板100的驅動模式為顯示驅動模式時,顯示驅動器IC 200施加共用電壓於該等電極120,當面板100的驅動模式為觸控驅動模式時,施加觸控掃描訊號於每一組,並且施加資料訊號於資料線130。此外,該顯示裝置還包括觸控IC 300,其產生並施加觸控掃描訊號於顯示驅動器IC 200。除DC電壓產生器之外,本發明的其他實施例基本與本發明的該實施例相同,因此不提供重複說明。下面將重點描述顯示驅動器IC 200。
根據本發明其他實施例之顯示驅動器IC 200包括:觸控驅動器210,用於施加共用電壓於該等組110或者依組施加觸控掃描訊號;以及顯示驅動器220,用於施加資料訊號於資料線130。這裡,施加於資料線130的資料訊號為具有與觸控掃描訊號相同相位的訊號。
具體而言,根據本發明另一實施例的顯示驅動器IC 200包括:觸控驅動器210,用於當面板100的驅動模式為顯示驅動模式時,施加由包括在顯示驅動器IC 200中的共用電壓產生器產生的共用電壓於電極120,並且當面板100的驅動模式為觸控驅動模式時,將電極120劃分為3組以依序地施加觸控掃描訊號於該3組。此外,顯示驅動器IC 200還包括顯示驅動器220,用於當面板100的驅動模式為觸控驅動模式時,將具有與觸控掃描訊號相同相位的資料訊號施加於形成在接收觸控掃描訊號的3組的任意一組之下的資料線130。
例如,如第3圖所示,當用於感測觸控位置的觸控掃描訊號自觸控驅動器210經由連接線230施加於第一組111時,具有與觸控掃描訊號相同相位的資料訊號自顯示驅動器220施加於形成在包括在第一組111中的電極之下的資料線131。當觸控掃描訊號施加於第二組112時,具有與觸控掃描訊號相同相位的資料訊號自顯示驅動器220施加於形成在包括在第二組112中的電極之下的資料線132。當觸控掃描訊號施加於第三組113時,具有與觸控掃描訊號相同相位的資料訊號自顯示驅動器220施加於形成在包括在第三組113中的電極之下的資料線133。
尤其是,向包括在接收觸控掃描訊號的一組中的電極之下的資料線所施加的資料訊號可以為一訊號,其中自觸控IC 300施加於觸控驅動器220的觸控掃描訊號傳送至顯示驅動器210。
這裡,具有與觸控掃描訊號相同相位的資料訊號施加於形成在包括在接收觸控掃描訊號的一組中的電極之下的資料線,這降低了在接收觸控掃描訊號的一組中的電極與形成在該組之下的資料線之間形成的初始電容,從而防止觸控感應的降低。
如上所述,這是因為電位差由於向包括在該組中的電極施加的觸控掃描訊號而產生於包括在接收觸控掃描訊號的一組中的電極與資料 線之間。然而,經由向資料線施加具有與觸控掃描訊號相同相位的資料訊號來最小化電極與資料線之間的電位差,從而導致該初始電容的降低。
現在參考第3圖詳細描述根據本發明其他實施例之具有整合式觸控螢幕的顯示裝置的驅動方法。
根據本發明的實施例,當面板100的驅動模式為顯示驅動模式時,由包括在顯示驅動器IC 200中的共用電壓產生器產生的共用電壓同時施加於電極120,並且電極120接收自顯示驅動器IC 200的共用電壓以作為面板100的顯示驅動的電極。
然而,當面板100的驅動模式為觸控驅動模式時,在觸控IC 300中用於觸控感測而產生的3個劃分的觸控掃描訊號施加於觸控驅動器210,並且在顯示驅動器IC 200中產生的資料訊號經由顯示驅動器220施加於資料線130。這裡,該資料訊號可以為由觸控驅動器210產生且施加於顯示驅動器220的訊號,尤其是可以為觸控掃描訊號。
隨後,向觸控驅動器210施加的3個劃分的觸控掃描訊號均經由連接線230施加於形成在面板100中的各自的三組110。例如,在該三個劃分的觸控掃描訊號中,第一觸控掃描訊號經由連接線230施加於第一組111,第二觸控掃描訊號施加於第二組112,以及第三觸控掃描訊號施加於第三組113。這裡,第一至第三觸控掃描訊號的每一個均依序地施加於包括在對應組中的複數個電極。在每一組中的複數個電極也連接至連接線230。
同時,資料訊號自顯示驅動器220依序地施加於接收形成在包括在面板100中的觸控掃描訊號的一組中的電極之下的資料線。這裡,分別施加於形成在包括在接收觸控掃描訊號的該組中的電極之下的資料線的資料訊號為具有與觸控掃描訊號相同相位的訊號。
例如,當觸控掃描訊號自觸控驅動器210施加於第一組111時,具有與觸控掃描訊號相同相位的複數個資料訊號分別自顯示驅動器220施加於形成在包括在第一組111中的電極之下的資料線131。當觸控掃描訊號自觸控驅動器210施加於第二組112時,具有與觸控掃描訊號相同相位的複數個資料訊號分別施加於形成在包括在第二組112中的電極之下的資料線132。當觸控掃描訊號自觸控驅動器210施加於第三組113 時,具有與觸控掃描訊號相同相位的複數個資料訊號分別施加於形成在包括在第三組113中的電極之下的資料線133。
在本發明的另一實施例中,形成在接收觸控掃描訊號的該組之下的複數個資料線分別接收具有與觸控掃描訊號相同相位的複數個資料訊號,並且降低在接收觸控掃描訊號的一組中的電極與形成在包括在該組中的電極的資料線之間形成的初始電容,從而防止觸控感應的降低。
這是因為電位差由於向包括在該組中的電極施加的觸控掃描訊號而產生於包括在接收觸控掃描訊號的一組中的複數個電極與資料線之間。然而,經由將具有與觸控掃描訊號相同相位的資料訊號施加於資料線而最小化電極與資料線之間的電位差,從而導致初始電容的降低。
根據本發明的實施例,在自電容式觸控螢幕中,當觸控掃描訊號施加於一組時,經由將DC電壓施加於包括在接收觸控掃描訊號的該組中的電極之下的資料線,使該組的電極與該組的底部資料線之間的初始電容達到最小,從而能夠產生更精確的觸控感應。
此外,根據本發明的實施例,在自電容式觸控螢幕中,當觸控掃描訊號施加於一組時,經由將具有與觸控掃描訊號相同相位的資料訊號施加於包括在接收觸控掃描訊號的該組中的電極之下的資料線,使該組的電極與該組的底部資料線之間的初始電容達到最小,從而能夠產生更加精確的觸控感應。
顯而易見的是,所屬領域中的具有通常知識者在不脫離本發明的精神或範圍的情況下,可以對本發明作出各種修改及變換。因此,本發明涵蓋所附申請專利範圍及其等同的範圍內所提供的本發明的修改及變換。
