Abstract
一種用於電光顯示器之背板,該背板包括一資料線;一電晶體;一像素電極,其經由該電晶體連接至該資料線,該像素電極被定位成與該資料線之一部分相鄰,以便產生一資料線/像素電極電容。該背板進一步包括一屏蔽電極(shield electrode),其配置成與該資料線之至少一部分相鄰,以便減少該資料線/像素電極電容。
Description
本申請案主張2016年5月31日所提出之美國臨時申請案第62/343,551號之優先權,在此以提及方式併入該美國臨時申請案之全部。
本發明係有關於電光顯示裝置,更具體地,係有關於包括薄膜電晶體陣列之顯示背板。
本發明係有關於電光顯示器之背板。更具體地,本發明係有關於可以有效降低像素電極串擾(crosstalk)之顯示像素設計。
術語「電光」應用於材料或顯示器,在此用以以其成像技術中的傳統含義提及具有在至少一種光學性質上不同的第一及第二顯示狀態之材料,材料藉由施加電場至材料而從其第一顯示狀態改變至其第二顯示狀態。雖然光學性質通常是人眼可感知的顏色,但它可以是另一種光學性質,例如,光透射、反射率、發光亮度或者在意欲用於機器讀取的顯示器之情況下,是可見範圍外之電磁波長的反射率變化之意思的偽色
(pseudo-color)。
術語「灰色狀態(gray state)」在此用以以其成像技術中之傳統含義提及在像素之兩個極端光學狀態間的狀態,以及沒有必定暗指這兩個極端狀態間之黑白轉移(black-white transition)。例如,下面所提及之數個E Ink專利及公開申請案描述電泳顯示器,其中,極端狀態為白色及深藍色,以致於中間「灰色狀態」實際上是淺藍色。更確切地,如所述,光學狀態之變化可能根本不是顏色變化。術語「黑色」及「白色」在下面可以用以提及顯示器之兩個極端光學狀態,以及應該了解到,通常包括完全不是黑色及白色之極端光學狀態,例如,前述白色及深藍色狀態。術語「單色(monochrome)」在下面可以用以表示在不具有中間灰色狀態下只將像素驅動至它們的兩個極端光學狀態之驅動方案。
術語「雙穩態(bistable)」及「雙穩性(bistability)」在此用以以該項技藝中之傳統含義提及顯示器包括具有在至少一種光學性質上不同的第一及第二顯示狀態之顯示元件,以及在以有限持續時間之定址脈波驅動任何一既定元件,以呈現它的第一或第二顯示狀態後及在終止該定址脈波後,那個狀態持續至少數次,例如,至少4次;該定址脈波需要最短持續時間來改變該顯示元件之狀態。公開的美國專利申請案第2002/0180687號(亦參見對應的國際申請案公開第WO 02/079869號)顯示具有灰階(gray scale)能力的一些以粒子為基礎之電泳顯示器不僅具有穩定的極端黑色及白色
狀態,而且具有穩定的中間灰色狀態,以及一些其它類型的電光顯示器亦同樣是如此。此類型之顯示器可適當地稱為「多穩態(multi-stable)」而不是雙穩態,但是為了方便起見,在此可以使用術語「雙穩態」來涵蓋雙穩態及多穩態顯示器。
術語「脈衝(impulse)」在此以電壓相對於時間的積分之傳統含義來使用。然而,一些雙穩態電光介質充當電荷轉換器(charge transducer),以及對於這樣的介質,可以使用脈衝之替代定義,亦即,電流相對於時間之積分(等於所施加之總電荷量)。應該根據介質充當電壓-時間脈衝轉換器或電荷脈衝轉換器,使用脈衝之適當定義。
讓渡給Massachusetts Institute of Technology(MIT)及E Ink Corporation或在它們的名義下之描述膠囊化電泳介質的許多專利及申請案最近已被公開了。這樣的膠囊化介質包括許多小膠囊,每一膠囊本身包括一個包含懸浮在液體懸浮介質中之電泳移動粒子的內相(internal phase)及一個包圍該內相之膠囊壁。通常,膠囊本身保持在高分子黏著劑中,以形成位於兩個電極間之黏著層(coherent layer)。在這些專利及申請案中所述之技術包括:
(a)電泳粒子、流體及流體添加劑;參見例如,美國專利第7,002,728及7,679,814號;
(b)膠囊、黏著劑及膠囊化製程;參見例如,美國專利第6,922,276及7,411,719號;
(c)包含電光材料之薄膜及次總成(sub-assemblies);參見例如,美國專利第6,982,178及7,839,564號;

許多前述專利及申請案認知到,包圍在膠囊化電泳介質中之離散微膠囊的壁可以連續相(continuous phase)來取代,因而產生所謂的高分子分散電泳顯示器(polymer-dispersed electrophoretic display),其中電泳介質包括複數離散液滴的電泳流體及高分子材料的連續相,以及縱使沒有離散膠囊薄膜與每一個別液滴結合,可以將在這樣的高分子分散電泳顯示器中之電泳流體的
離散液滴視為膠囊或微膠囊;參見,例如,前述2002/0131147。於是,為了本申請案之目的,將這樣的高分子分散電泳介質視為膠囊化電泳介質之亞種(sub-species)。
一種膠囊化電泳顯示器通常不會受到傳統電泳裝置之群集(clustering)及沉降(settling)失效模式的影響,並提供另外的優點,例如,在各種柔性及剛性基材上印刷或塗佈顯示器的能力。(文字「印刷」之使用意欲包括所有形式之印刷及塗佈,其包括但不侷限於:預計量式塗佈(pre-metered coatings)(例如:方塊擠壓式塗佈(patch die coating)、狹縫型或擠壓型塗佈(slot or extrusion coating)、斜板式或級聯式塗佈(slide or cascade coating)及淋幕式塗佈(curtain coating));滾筒式塗佈(roll coating)(例如:輥襯刮刀塗佈(knife over roll coating及正反滾筒式塗佈(forward and reverse roll coating));雕型塗佈(gravure coating);濕式塗(dip coating);噴灑式塗佈(spray coating);彎月形塗佈(meniscus coating);旋轉塗佈(spin coating);手刷塗佈(brush coating);氣刀塗佈(air knife coating);絲網印刷製程(silk screen printing processes);靜電印刷製程(electrostatic printing processes);熱印刷製造(thermal printing processes);及噴墨印刷製程(inkjet printing processes));以及其它相似技術。)因此,結果的顯示器係具有彈性的。再者,因為可以(使用各種方法)印刷顯示介質,所以顯示器本身可以便宜地製造。
一種相關類型的電泳顯示器係所謂的「微細
胞電泳顯示器(microcell electrophoretic display)」。在微細胞電泳顯示器中,沒有將帶電粒子及懸浮流體裝入微膠囊中,但是取而代之,將其保留在載體介質(carrier medium)(通常是高分子薄膜)內所形成之複數個空腔(cavities)中。參見,例如,國際申請案公開第WO 02/01281號及公開的美國申請案第2002/0075556號,兩者皆被讓渡給Sipix Imaging Inc.。
前述類型的電光顯示器係雙穩態的且通常使用於反射模式中,但是如某些前述專利及申請案所述,這樣的顯示器可以操作於「光柵模式(shutter mode)」中,在光柵模式中,電光介質係用以調整光的穿透,以致於顯示器操作於穿透模式中。包括高分子分散液晶的液晶當然亦是電光介質,但是通常不是雙穩態的且操作於穿透模式中。下面所述之本發明的某些實施例被侷限用於反射型顯示器,而其它實施例可以使用於反射型及穿透型顯示器,其包括傳統液晶顯示器。
不論顯示器係反射型或透射型且不論電光介質是否係雙穩態的,為了獲得高解析度顯示,顯示器的個別像素必須是可定址的,而不會受到相鄰像素的干擾。一種用以達成此目的之方法提供非線性元件(例如,電晶體或二極體)陣列且至少一非線性元件與每一像素相關連,以生產一種「主動矩陣(active matrix)」顯示器。一個定址像素電極用以定址一個像素,該定址像素電極經由相關非線性元件連接至適當電壓源。通常,當非線性元件為電晶體時,像素電極連接至電晶體之汲極,以
及在下面敘述中將採用此配置,但是它本質上是任意的,因而像素電極可以連接至該電晶體之源極。傳統上,在高解析度陣列中,像素係以列與行之2維陣列來配置,以致於任一特定像素係由一指定列與一指定行的交點來唯一界定。在每一行中之所有電晶體的源極連接至單一行電極,而在每一列中之所有電晶體的閘極連接至單一列電極;再者,源極至列及閘極至行的分配係常規的,但是本質上是任意的,以及如果需要的話,可以是顛倒的。列電極連接至一個列驅動器,列驅動器本質上確保在任何既定時間只選擇一列,亦即,施加電壓至被選列電極,以確保在被選列中之所有電晶體係導通的,而施加電壓至所有其它列,以確保在這些未被選列中之所有電晶體保持未導通。行電極連接至行驅動器,行驅動器將電壓施加至不同的行電極,其被選來驅動在被選列中之像素至它們期望的光學狀態。(前述電壓係相對於一共同前電極,該共同前電極在傳統上係設置在電光介質之與非線性陣列相對的一側且延伸橫跨整個顯示器。)在稱為「行定址時間(line address time)」之預選間隔後,取消被選列、選擇下一列及改變在行驅動器上之電壓,以寫入顯示器之下一行。重複此程序,以便以一列接一列方式寫入整個顯示器。
製造主動矩陣顯示器的製程已經很成熟。例如,可以使用各種沉積和微影技術來製造薄膜電晶體。電晶體包括閘極、絕緣介電層、半導體層以及源極和汲極。對閘極施加電壓提供橫跨介電層之電場,這顯著增
加了半導體層的源極-汲極導電率。此變化允許源極和汲極間之電導。通常,閘極、源極及汲極被圖案化。一般地,半導體層亦被圖案化,以便最小化在相鄰電路元件間之雜散傳導(stray conduction)(亦即,串擾)。
液晶顯示器通常使用非晶矽(「a-Si」)薄膜電晶體(「TFT」)作為顯示像素的切換裝置。這樣的TFT通常具有底閘極構造。在一個像素內,薄膜電容器通常保持由切換TFT傳輸的電荷。電泳顯示器可以使用具有電容器之類似TFT,但是電容器的功能與液晶顯示器中之那些電容器的功能略有不同;參見前述審查中申請案序號第09/565,413號以及公開第2002/0106847及2002/0060321號。可以製造薄膜電晶體,以提供高性能。然而,製造程序可能導致顯著的成本。
在TFT定址陣列中,像素電極在行位址時間期間透過TFT來充電。在行位址時間期間,藉由改變施加的閘極電壓,將TFT切換至導通狀態。例如,對於n型TFT,閘極電壓被切換至「高」狀態,以將TFT切換至導通狀態。
其中Cgp係閘極像素電容,Cp係像素電容,Cs係儲存
電容,△係TFT係有效地處於空乏時閘極電壓偏移的部分。此電壓偏移通常稱為「閘極饋通」。
可以藉由將上極板電壓(被施加至共用前電極的電壓)移位有一個量△Vp來補償閘極饋通。然而,難題出現,因為由於Cgp因像素而異,△Vp亦因像素而有所不同。因此,即使當使上極板移位,以補償平均像素電壓偏移時,電壓偏差可能持續下去。電壓偏差可能造成像素的光學狀態錯誤,並使電光介質劣化。
Cgp的變化例如係由用以形成TFT之閘極及源極-汲極位準的兩個導電層間之未對準;閘極介質厚度的變化;以及線蝕刻的變化(亦即,線寬誤差)所引起。
再者,額外的電壓偏移可能由在向顯示像素提供驅動波形的資料線與像素電極之間發生的串擾所引起。與上述的電壓偏移相似,即使當顯示像素沒有被定址(例如,相關的像素TFT處於空乏中)時,資料線與像素電極之間的串擾可能由兩者之間的電容耦合所引起。這樣的串擾可能導致不期望的電壓偏移,因為這可能造成諸如影像條紋的光學偽影。
可以藉由改變像素電極和/或數據線之幾何尺寸,減少資料線與像素電極之間的電壓偏移。例如,可以縮小像素電極的尺寸,以擴大電極與資料線之間的間隙。在一些其它實施例中,可以改變像素電極與資料線之間的材料之電性,以減少串擾。例如,可以增加像素電極與其相鄰資料線之間的絕緣薄膜之厚度,以減少電容耦合。然而,這些方法在實現上可能是昂貴的,並
且在某些情況下,由於諸如裝置尺寸限制的設計限制而變得不可能。因此,需要以簡單且便宜實現方式來減少顯示像素中的串擾。
本發明提供用以減少可以合宜地應用至當前可用顯示器背板之顯示像素中的串擾及電壓偏移之裝置。
本發明提供一種用於電光顯示器之背板,該背板可以包括一資料線;一電晶體;以及一像素電極,其經由該電晶體連接至該資料線,其中該像素電極可以被定位成與該資料線之一部分相鄰,以便產生一資料線/像素電極電容。該背板可以進一步包括一屏蔽電極(shield electrode),其配置成與該資料線之至少一部分相鄰,以便減少該資料線/像素電極電容。

如上所述,本發明提供一種用於電光顯示器之顯示背板,其中減少在像素電極與資料線之間的串擾。這樣的背板可以包括顯示像素,其中由電容耦合所引起的串擾可被額外的屏蔽電極來遮蔽。在一些實施例中,屏蔽電極可以位於與資料線相同的裝置層上及/或像素電極與資料之間的間隙中。
應該理解到,在此所述之背板可以擴展到包括設置在背板上且覆蓋像素電極的電光介質層之電光顯示器。這樣的電光顯示器可以使用先前論述之任何類型的電光介質,例如,電光介質可以是液晶、旋轉雙色構件(rotating bichromal member)或電致變色介質(electrochromic medium)或者電泳介質,優佳的是膠囊化電泳介質。在一些實施例中,當使用電泳介質時,複數個帶電粒子可以在電場的影響下移動通過懸浮流體。當與液晶顯示器相較時,這樣的電泳顯示器可以具有良好的亮度和對比、寬視角、狀態雙穩性及低功率消耗的特性。
第1A圖說明使用TFT作為切換裝置之顯示像素100的上視圖。像素100可以包括用以作為至顯示像素之源極線且配置成向像素電極104提供切換信號之閘極線102。資料線106可以電耦合至像素電極104及閘極線102,以便提供驅動信號(例如,波形)至像素電極104。此外,另一資料線108可以位於與像素電極104相鄰且在遠離資料線104之相對側上,以便提供驅動波形至鄰近的
像素電極(未示出)。根據第1A圖所示之上視圖,資料線106及108分別以間隙空間116及118與像素電極104隔開。現在參考第1B圖,第1B圖顯示第1A圖中呈現之顯示像素100的剖面圖。如圖所示,顯示像素100可以包括三個以上裝置層110、112、114。在一些實施例中,像素電極104可以位於第一裝置層110上,以及資料線106,108可以位於第三裝置層114上,其中第一裝置層110與第三裝置層114係由第二裝置層112來絕緣。第二裝置層112可以包括像氮化矽之介電材料或或其它可相比的電介質材料,以致於第一及第三裝置層彼此電絕緣。在操作中,例如,當顯示像素100被定址(亦即,像素TFT處於導通中)時,將驅動電壓信號(亦即,波形)從資料線106傳送至像素電極104。然而,當顯示像素100未被定址(亦即,相關的像素TFT處於空乏中)且資料線106、108與像素電極104之間的電容耦合仍然促使像素電極104之電壓值偏移時,可能會出現問題。如第1B圖所示,電場可以透過第二介電裝置層112耦合於資料線106、108與像素電極104之間。
如上所述,資料線106、108與像素電極104之間的電場耦合產生不期望的串擾,並且這樣的串擾可能造成不需要的光激過渡(optical transitions)。用以降低這樣的串擾並在下面作更詳細討論的一種方法係將屏蔽電極定位在資料線106、108與像素電極104之間。
第2A及2B圖說明TFT像素200之另一個實施例,其中可以藉由將一個以上屏蔽電極212、214放置在
間隙空間208及210中,減少資料線202、204與像素電極206之間的電容耦合。
在此配置中,屏蔽電極212、214可以放置在資料線202、204旁邊並且連接至電壓源(例如,接地),其中屏蔽電極212、214可以在主動矩陣掃描期間大致保持固定的電壓值。如第2A和2B圖所示,屏蔽電極212、214可以位於資料線202、204附近且在與資料線202、204相同的裝置層上。再者,即使只要可達成串擾的減少,可以合宜地採用其他幾何形狀,屏蔽電極212、214可以實質上具有相同的幾何形狀,或者甚至相對於資料線202、204成鏡像。以這種方式,資料線202、204之位置比較靠近相鄰的屏蔽電極212、214,而不是像素電極206,以及取而代之,來自資料線202、204之電場的較大部分將耦合至屏蔽電極212、214。在一些實施例中,電場的這種轉向可能是由於在資料線202、204與屏蔽電極212、214之間具有較少的介質材料的事實所引起,以及因此,電場從資料線202、204至屏蔽電極212、214比至像素電極206具有更容易的行進路徑。換句話說,像素電極206與附近的資料線202、204之間的互電容因屏蔽電極212、214的存在而減少。結果是,當資料線電壓偏移時,由於屏蔽電極的存在,附近的像素電極透過電容耦合將經歷較小的電壓變化。
應該理解到,只要減少像素電極與資料線之間的漏電容,可以改變屏蔽電極的放置及幾何尺寸。例如,不同於第2B圖所示,其中屏蔽電極212、214的部分
與像素電極206重疊或延伸於像素電極206的下方,在一些實施例中,屏蔽電極可以整個位於像素電極與相鄰的控制資料線之間的間隙空間中,以致於在像素電極與資料線之間沒有垂直重疊。
在一些實施例中,屏蔽電極可以位於不同於資料線之裝置層中。再者,如第3圖所示,屏蔽電極的尺寸可能足夠大(例如,比資料線寬),以在垂直方向上完全遮蔽資料線與像素電極。第3圖顯示像素電極300的剖面圖,其中屏蔽電極302、304位於第二裝置層306上,其完全遮蔽在第三裝置層312上之下方的資料線308、310與像素電極314。
在第4圖所示的又另一個實施例中,顯示像素400可以包括與閘極線406平行設置的額外資料線402、404。額外資料線402、404可以位於與資料線408、410不同的裝置層上,並且可以經由一個以上介層412、414連接至資料線408、410。在這種配置中,屏蔽電極(未顯示)可以任選地放置在額外資料線402、404與像素電極416之間,以減少串擾。
應該理解到,即使在先前實施例中所述的屏蔽電極可以在主動矩陣掃描期間耦合至固定電壓(例如,接地),以維持大致固定的電壓值,在一些其它實施例中,屏蔽電極可以配置成對其它大致固定電壓電極具有強電容耦合。以這種方式,屏蔽電極將仍然能夠保持足夠穩定的電壓,並且減少串擾而不被外部電子裝置主動驅動。
從上述可以看出,本發明可以提供一種用以減少顯示像素電壓偏移的背板。對於該項技藝人士將顯而易見的是,在不脫離本發明之範圍的情況下,可以對上述本發明的具體實施例進行許多改變及修改。於是,整個前面敘述將以說明性而不是限制性的意思來解釋。
