Abstract

描述一種發光組件。在一個實施例中,一或更多個發光二極體(LED)裝置及一或更多個微控制器接合至基板的相同側面,其中一或更多個微控制器開關及驅動一或更多個LED裝置。

Description

智能像素照明及顯示之微控制器
本發明係關於發光二極體(light emitting diode;LED)微控制器。更特定而言,本發明的實施例係關於供顯示或照明應用中使用的LED微控制器。
使用LED裝置的平板顯示器在寬廣的電子裝置範圍(從小的手持電子裝置至大的戶外顯示器)中變得流行。高分辨率LED顯示器(諸如現代電腦顯示器、智慧型電話及電視機中使用的彼等LED顯示器)通常使用主動矩陣顯示器結構。在主動矩陣顯示器中,主動驅動電路系統附接於每一像素或子像素,以允許針對缺乏被動矩陣顯示器的單獨的像素的準確電壓開關。準確電壓開關允許相較於被動矩陣顯示器改良的圖像品質及回應時間。在習知的主動矩陣顯示器中,使用驅動發射元件的薄膜電晶體(thin-film transistor;TFT)背板實施每一像素處的開關電路系統。發射主動矩陣顯示器中使用的典型TFT開關電路為2T1C電路,該2T1C電路包含二個電晶體及一個電容器,但是更先進的TFT電路亦為可能的。
使用TFT背板允許關於被動矩陣顯示器的改良的準確度,然而,使用薄膜電晶體背板不是沒有缺陷。高品質TFT製造為昂貴的。由於製造製程中涉及高溫,故最高品質的TFT要求在石英基板上製造。較低溫度製程可用於玻璃基板,然而,所得電晶體可遭受低載子移動性,減少電晶體的導電性。電流洩漏及功率消耗亦可成為問題,及均勻性問題可出現在製造製程期間的各點處。
描述用於控制發光二極體的智能像素微控制器。智能像素微控制器可用於替代用於LED及LCD顯示技術中的TFT背板及可增加之前在顯示器中使用薄膜電晶體作為開關及驅動元件時不可能的新功能。在一實施例中,發光組件包括一或更多個發光二極體(LED)裝置及一或更多個微控制器,該一或更多個微控制器開關及驅動該一或更多個LED裝置。該一或更多個LED裝置及一或更多個微控制器接合至基板的相同側面。在實施例中,使用材料(諸如銦、金、銀、銅或以上各者的合金)將LED裝置及微控制器接合至基板。
在一個實施例中,智能像素積體電路經配置用於類比輸入及具有包含電子設備的輸入塊及輸出塊。在此實施例中,使用施加至掃描線路及資料線路的電壓控制智能像素微控制器,類似於主動矩陣顯示器。在類比形式中,智能像素微控制器可接受至少一個類比資料輸入以控制至少一個LED裝置,但是亦可使用單個微控制器控制多個LED裝置。在一個實施例中,智能像素微控制器使用數位儲存補充類比電路 系統,從而促進適應性刷新速率及顯示自我刷新。在一個實施例中,電容儲存用於儲存類比輸入。
在一個實施例中,智能像素微控制器經配置用於數位輸入,及具有包含數位邏輯的輸入塊及輸出塊以及具有嵌入記憶體的儲存模組。數位輸入可由數位匯流排或點至點資料鏈路的方式獲得。可使用單個微控制器控制多個LED裝置或感測器裝置。在一個實施例中,適應性顯示更新由每一積體電路中的資料儲存促進。
在一個實施例中,複數個LED裝置接合至如微控制器接合的基板的相同側面及與微控制器電性連接。LED裝置可用作顯示器中的子像素及可以紅色、綠色、藍色(red,green,blue;RGB)子像素佈置配置。其他子像素佈置及方案亦為可能的。在一實施例中,發光組件包括接合至基板的相同側面的LED裝置陣列及微控制器陣列。微控制器陣列中微控制器的數目小於LED裝置陣列中LED裝置的數目。在一實施例中,每一微控制器與複數個像素電性連接以驅動每一像素中的複數個LED裝置。
除了控制顯示器的發射元件之外,微控制器可與一或更多個光學、電性或熱感測器耦合。替代地,微控制器可包括一或更多個感測器。在一個實施例中,智能像素微控制器與一或更多個壓力感測器耦合,該一或更多個壓力感測器可用於當觸摸顯示器時在顯示器上提供視覺顯示反饋,或在觸摸顯示器時傳送使用者輸入。在一個實施例中,感測器可用於偵測顯示器的白點隨時間的漂移,及可不時再校正顯示 器以維持持續的白點。
亦揭示使用接收基板、一或更多個傳輸頭及一或更多個載體基板製造顯示或照明裝置的方法的一個實施例。可藉由在接收基板上放置微尺度子像素陣列製造照明或顯示裝置,其中接收基板經製備具有分配線路以耦合微尺度子像素陣列的部件。在一實施例中,製造發光組件的方法包括以下步驟:在承載複數個LED裝置的基板上方定位一傳輸頭陣列,拾取複數個LED裝置及在接收基板上放置複數個LED裝置。針對承載其他複數個LED裝置(例如,具有不同的發光特徵)的個別基板可重複此製程。可使用相同或不同的傳輸頭陣列。相同或不同傳輸頭陣列隨後定位在承載複數個微控制器的基板上方,拾取複數個微控制器及將微控制器放置在如複數個LED裝置放置的接收基板的相同側面。根據本發明的實施例,傳輸頭陣列可根據靜電原理操作。複數個LED裝置及微控制器亦可接合至接收基板。在一實施例中,藉由使用各自的傳輸頭陣列加熱複數個LED裝置及複數個微控制器實現接合。藉由使用傳輸頭陣列熱壓接合亦可實現接合。此外,一或更多個感測器裝置亦可使用靜電傳輸頭放置在接收基板上。

藉由舉例而非限制的方式在隨附圖式之諸圖中圖示 實施例,在該等隨附圖式中:第1圖為根據一個實施例的智能像素微矩陣的電路圖;第2圖為根據一個實施例的智能像素微控制器結構的方塊圖;第3圖為根據一個實施例的替代智能像素微控制器結構的方塊圖;第4圖為根據實施例的智能像素微控制器輸入塊的方塊圖;第5A圖、第5B圖為根據實施例的另一智能像素輸入塊的替代的方塊圖;第6圖為根據實施例的又一智能像素輸入塊的方塊圖;第7圖為圖示根據實施例的智能像素輸出塊的方塊圖;第8圖為圖示根據實施例的另一智能像素輸出塊的方塊圖;第9圖圖示根據實施例的示例性智能像素顯示系統;第10圖為圖示根據實施例的示例性像素更新時序的時序圖;第11圖為根據實施例的智能像素訊框更新訊號的時序圖;第12A圖、第12B圖及第12C圖為圖示根據實施例 的各種示例性微矩陣配置的方塊圖;第13圖為根據實施例的具有感測器輸入的替代智能像素微控制器結構的方塊圖;第14圖為根據實施例的具有資料中繼器的替代智能像素微控制器結構的方塊圖;第15圖為根據實施例的產生智能像素微矩陣顯示或照明基板的一個方法的流程圖;第16圖為根據實施例的將微裝置的微裝置基板處理為接收基板的圖示;以及第17圖為根據實施例的由在顯示或照明基板上組裝的智能像素陣列產生的智能像素顯示組件的圖示。
本發明的實施例提供用於發光裝置的「智能像素」微控制器。智能像素微控制器利用基於晶圓的微控制器裝置的效能、效率及可靠性替代用於形成TFT背板的薄膜電子設備。在一個實施例中,一或更多個發光裝置與智能像素微控制器耦合以產生智能像素發光裝置。智能像素發光裝置的發射元件可為一或更多個發光二極體(LED)裝置、一或更多個有機LED(organic LED;OLED)裝置或一或更多個微LED(μLED)裝置。由於基板沒必要經歷TFT製造製程,故缺少TFT製造製程允許使用一系列基板(包括剛性的、半剛性的或撓性基板、玻璃基板、塑性基板或任何應用適當的基板)製造智能像素「微矩陣」。
智能像素裝置可由傳輸一或更多個LED裝置及一或 更多個智能像素微控制器至接收基板上產生,該接收基板已經製備有分配線路以耦合每一智能像素微控制器至該智能像素微控制器各自的LED裝置、其他智能像素控制器及/或外部裝置及電路。除了一或更多個LED裝置以外或代替一或更多個LED裝置,智能像素裝置亦可包括一或更多個感測器。微控制器(μC)、LED裝置及感測器裝置接合至基板表面的相同側面。接合可使用各種連接進行,諸如但不限於,引腳、導電墊、導電凸塊及導電球。金屬、金屬合金、焊料、導電聚合物或導電氧化物可用作形成引腳、墊、凸塊或球的導電材料。在實施例中,μC、LED裝置或可選的感測器裝置上的導電觸點經熱壓接合至基板上的導電墊。以此方式,接合可用作與μC、LED裝置或感測器裝置的電性連接。在實施例中,接合包括合金接合導電觸點與導電墊。舉例而言,導電觸點或導電墊可包括用於接合的材料,諸如銦、金、銀、錫或銅。在實施例中,當接合在一起時,導電觸點及導電墊形成合金,諸如銦-金、錫-金、錫-銀-銅。可與本發明的實施例一起使用的其他示例性接合方法包括但不限於,熱接合及熱超聲接合。在實施例中,μC、LED裝置或感測器裝置接合至與基板上的分配線路電性連接的著陸墊以電性耦合一或更多個LED裝置至智能像素μC。接收基板可基於智能像素微矩陣的應用變化。在一個實施例中,使用顯示基板以形成智能像素微矩陣LED顯示裝置,其中智能像素被用作高分辨率顯示器中的圖片元素。
在一個實施例中,智能像素微矩陣在適合用於照明 裝置中的接收基板上構建。智能像素微控制器可用於維持發射光的準確亮度、均勻性及顏色控制。在一個實施例中,針對液晶顯示器(liquid crystal display;LCD)裝置,智能像素微矩陣用作LED背光。與黃色、藍色-黃色或白色熒光體組合的藍色或UV LED可用於為LCD顯示器提供白色背光。白光亦可由使用或不使用熒光體之單個顏色LED裝置的不同組合產生。除了白光照明之外,額外的單個顏色LED裝置(例如,紅色、琥珀色、綠色、藍色等等)亦可用於提供比其他可能使用白色背光的裝置更寬的色域及顯色指數。
一或更多個智能像素微控制器亦可耦合以形成微控制器網路。可使用微控制器層級,其中分層佈置存在於微控制器之間。多個類型微控制器可用於各種應用,及微控制器每一者可連接至共用資料匯流排,以菊鏈耦合或可無線通訊。微控制器網路可賦能故障容限及可用於決定智能像素微矩陣的狀態。
在一個實施例中,賦能智能像素微矩陣中智能像素微控制器及其他裝置之間的雙向通訊。一或更多個感測器可與智能像素微控制器以及發射元件耦合。感測器可為環境光感測器、光學感測器、電性感測器或熱感測器。在一個實施例中,使用壓力感測器(例如)以當觸摸顯示器時在顯示器上提供視覺顯示反饋或在觸摸顯示器時傳送使用者輸入。在智能像素微矩陣顯示器中,感測器可用於偵測顯示器的白點隨時間漂移,及可不時再校正顯示器以維持持續的白點。
在一個實施例中,智能像素元件為藉由耦合微尺度 子像素控制器(μC)裝置與微LED(μLED)裝置產生的微尺度裝置。「微尺度」、「微LED裝置」、「μLED裝置」、「μC裝置」及「微尺度像素控制器」中的術語「微」皆代表尺度1至100μm。舉例而言,每一μLED或每一μC裝置可具有1至100μm的最大(x,y)大小。然而,將理解,基於應用,本文描述的實施例可適用於更大的及可能更小的尺寸尺度。在一個實施例中,微尺度感測器裝置伴隨μLED裝置一起使用。根據一些實施例可用作微尺度微控制器裝置的示例性μLED裝置及微晶片在美國專利申請案第13/3711,554號中描述。然而,實施例不受此限制及美國專利申請案第13/3711,554號中描述的μLED裝置及微晶片意謂示例性的及非限制性的。相較於針對LCD或OLED發射的5至10瓦特,此類微LED裝置在發光方面為高效率的及可消耗極少的功率(例如,針對10吋顯示器為250mW)。在一個實施例中,使用OLED作為發射部件產生智能像素。在一個實施例中,無機LED用作智能像素的發射部件。然而,應理解,智能像素微尺度微控制器亦可與標準LED耦合,及應用不特定受限於微尺度LED。在一些實施例中,智能像素內部的μLED裝置及μC的尺寸由顯示器的像素間距及分辨率尺寸決定。示例性顯示尺寸在以下表格1中描述。
描述智能像素裝置的各種方法及配置,包括各種尺寸尺度的顯示、照明及背光照明配置。然而,某些實施例可在無需揭示的特定細節中的一或更多者的情況下實踐,或結合其他已知的方法及配置實踐。為了提供徹底的瞭解,闡明 許多特定細節,諸如特定配置、大小及製程。在一些情況下,沒有以特定細節描述眾所周知的技術及部件以避免不必要地模糊論述。
遍及此說明書,引用「一個實施例」及「實施例」等等指示關於實施例描述的特定特點、結構、配置或特徵包括在本發明的至少一個實施例中。因此,遍及此說明書各處的用語「在一個實施例中」、「在實施例中」等等的出現不一定代表本發明的相同實施例。此外,在一或更多個實施例中,特定特點、結構、配置或特徵可以任何適當的方式組合。
如本文使用的術語「在…上方」、「至」、「之間」及「在…上」可代表一個層關於其他層的相對位置。「在另一層上方」或「在另一層上」或接合「至」另一層的一個層可與另一個層直接接觸或可具有一或更多個介入層。層「之間」的一個層可直接接觸該等層或可具有一或更多個介入層。
如此說明書中關於裝置狀態使用的術語「打開」代表裝置的啟用狀態,及術語「關閉」代表裝置的停用狀態。如本文關於裝置接收的訊號使用的術語「打開」代表啟用裝置的訊號,及此關聯中使用的術語「關閉」代表停用裝置的訊號。裝置可由高電壓或低電壓啟用,取決於實施裝置的下層電子設備。舉例而言,由低電壓啟用PMOS電晶體裝置時由高電壓啟用NMOS電晶體。因此,將理解,用於PMOS電晶體裝置及NMOS電晶體裝置的「打開」電壓對應於相對的(低對高)電壓位準。亦將理解,當圖示或描述Vdd及Vss時,Vdd及Vss亦可指示一或更多個Vdd及/或Vss。舉例而言,數 位Vdd可用於資料輸入、數位邏輯、記憶體裝置等等,同時另一Vdd用於驅動LED輸出塊。
第1圖為根據一個實施例的智能像素微矩陣的電路圖。在一個實施例中,智能像素微矩陣100以微尺度智能像素微控制器(μC)積體電路裝置110代替習知主動矩陣顯示器的發射元件及TFT層,以開關及驅動一或更多個LED裝置115。在一個實施例中,智能像素微矩陣100在接收基板上被製造,該接收基板已經經製備具有分配線路125以耦合各種μC裝置110及LED裝置115。在一個實施例中,分配線路包括掃描線路及資料線路,該等掃描線路耦合一或更多個掃描驅動器V選擇,該等資料線路耦合一或更多個資料驅動器V資料。如所圖示的,LED裝置115耦合共用接地但每一者可具有分離的接地。在此圖中及在以下圖中,圖示的每一LED裝置115可代表單個LED裝置或可代表串聯、並聯或兩者組合佈置的多個LED裝置,使得多個LED裝置可根據相同控制訊號驅動。儘管第1圖中的示例性電路圖示三個控制輸入及六個LED輸出,然而實施例不受此限制。單個μC 110可控制顯示器上的多個像素或照明裝置的多個LED裝置115群組。在一個實施例中,單個μC 110可控制五十至一百個像素。
在一個實施例中,μC裝置110耦合一或更多個紅色、綠色及藍色LED裝置115,該等裝置發射不同顏色的光。在紅色-綠色-藍色(RGB)子像素佈置中,每一像素包括三個子像素,該三個子像素分別發射紅色、綠色及藍色光。RGB佈置為示例性的及彼等實施例不受此限制。額外的子像素佈置 包括紅色-綠色-藍色-黃色(red-green-blue-yellow;RGBY)、紅色-綠色-藍色-黃色-青藍色(red-green-blue-yellow-cyan;RGBYC)或紅色-綠色-藍色-白色(red-green-blue-white;RGBW)或其他子像素矩陣方案,其中像素可具有不同數目的子像素,諸如以商標名PenTile®製造的顯示器。
在一個實施例中,針對LCD裝置,智能像素微矩陣用於LED照明解決方案中或用作LED背光。當用作光源時,與黃色或藍色-黃色熒光體組合的藍色或UV LED可用於為LCD顯示器提供白色背光。在一個實施例中,使用一或更多個藍色LED裝置(諸如氮化銦鎵(indium gallium nitride;InGaN)LED裝置)的智能像素微矩陣與來自鈰摻雜的釔鋁石榴石(YAG:Ce3+)熒光體的黃色發光組合。在一個實施例中,紅色、綠色及藍色熒光體與近紫外線/紫外線(nUV/UV)InGaN LED裝置組合以產生白光。熒光體可接合至LED裝置表面或可使用遠端熒光體。除了白光發射,額外的紅色、綠色及/或藍色LED裝置亦可用於提供比另外可能使用白色背光的裝置更寬的色域。
第2圖為根據一個實施例的智能像素μC結構的方塊圖。在一個實施例中,智能像素μC裝置110具有輸入塊215及輸出塊225。在一個實施例中,智能像素μC裝置110具有額外的資料儲存模組210,該資料儲存模組210可為具有一或更多個電容器的類比資料儲存模組或可為由靜態隨機存取記憶體(static random access memory;SRAM)、動態隨機存取記憶體(dynamic random access memory;DRAM)或非揮發性記憶 體(諸如快閃記憶體)組成的數位資料儲存模組。輸入塊210與用於功率Vdd及接地Vss的輸入引腳以及一或更多個輸入引腳V資料(1)至V資料(n)耦合。智能像素μC 110為可配置的以接受至少一個輸入,該至少一個輸入可控制至少一個LED裝置或串聯、並聯或兩者組合的至少一組LED裝置,諸如可用於白色光源中的一或更多個LED裝置。在一個實施例中,三個輸入控制訊號控制具有紅色、綠色及藍色輸出的高達三個LED裝置(例如,LED1、LED2及LED3),以產生RGB子像素佈置。在一個實施例中,可控制三個以上LED裝置,以允許以下子像素佈置:諸如紅色-綠色-藍色-黃色(RGBY)、紅色-綠色-藍色-黃色-青藍色(RGBYC)或紅色-綠色-藍色-白色(RGBW)或其他子像素方案,其中像素可具有不同數目的子像素。在一個實施例中,智能像素μC 110具有耦合掃描驅動器輸入的V選擇輸入引腳,以提供一列選擇訊號。在一個實施例中,省略明顯的列選擇輸入,有利於使用資料輸入上的資料更新訊號。
在一個實施例中,輸出塊225配置為輸出電流至耦合至μC 110的各種發射裝置。在使用傳統的類比驅動技術的配置中,來自輸入資料線路的輸入電壓訊號經轉換為適當的電流以驅動耦合的子像素的每一者。舉例而言,V資料(1)的電壓輸入可驅動LED照明裝置中的LED1輸出。若μC 110輸入模組具有多個輸入,諸如V資料(1)至V資料(n),則輸出塊225可輸出LED1至LEDn的多達n個控制線路。串聯、並聯或串聯、並聯組合的一或更多個LED可耦合至一或更多個LED輸出。
在一個實施例中,智能像素μC 110具有資料儲存模組220以當接收輸入時儲存資料值。資料儲存模組220(該資料儲存模組220可為類比或數位儲存模組)儲存與每一顯示更新相關的資料。在一個實施例中,資料儲存模組220包含一或更多個電容器以儲存來自類比輸入塊的輸入的類比電壓。在一個實施例中,資料儲存模組220包含隨機存取記憶體(RAM)(諸如靜態RAM(SRAM)或動態RAM(DRAM))中的至少一個單元以儲存數位值。在一個實施例中,資料儲存模組220包含快閃記憶體。當賦能資料儲存模組220時,智能像素μC 110儲存每一像素的輸入資料及可以最低要求或無要求連續顯示資料,以供定期刷新靜態資料。代替地,像素可繼續顯示儲存的資料直至顯示控制器指示更新事件。此外,像素資料的多個訊框可以叢發方式傳送至智能像素μC 110及儲存在儲存模組220中。智能像素μC 110可隨後以特定更新速率或基於來自顯示控制器的更新訊號,經由多個訊框循環。
第3圖為根據一個實施例的替代智能像素μC的方塊圖。在一個實施例中,智能像素μC 310具有輸入塊315、資料儲存模組320及輸出塊325。如在第2圖圖示的類比變體110中,數位變體310具有Vdd及Vss電壓輸入以及可選的掃描線路或列選擇輸入V選擇205。在一個實施例中,數位智能像素μC 310的輸出(例如,LED1至LEDn)耦合LED照明裝置中或LED背光中的一或更多個LED裝置。在一個實施例中,三個或更多個LED裝置可以紅色-綠色-藍色(RGB)子像素 佈置或供智能像素微矩陣顯示裝置中使用的某一其他子像素矩陣控制。輸入採用數位輸入305的方式,數位輸入305可為至數位資料匯流排、數位資料鏈路或差分訊號介面的連接。
在一個實施例中,資料儲存模組320緩衝輸入塊315接收的輸入供輸出塊325後續使用。資料儲存模組325可包含記憶體(諸如DRAM、SRAM或快閃記憶體)以緩衝刷新循環之間的輸入資料。在一個實施例中,用於顯示訊框的所有輸入資料作為叢發訊息個別地發送至每一智能像素μC 310,該智能像素μC 310儲存用於附接的LED的像素或子像素資訊。輸出模組325可讀取儲存的資料及以標準更新速率或依賴內容的更新速率驅動附接的LED。
第4圖為根據一個實施例的智能像素μC輸入塊的方塊圖。在一個實施例中,輸入塊215耦合資料輸入405及列選擇或掃描輸入205。輸入塊215可使用取樣維持電路406的一或更多個變體。示例性取樣維持電路406具有一個電晶體T1 402及一個電容器Cs 404,但亦可使用更複雜的取樣維持電路。開關電晶體402可為任何類型的絕緣閘極場效電晶體,諸如n型或p型半導體電晶體。在此配置中,開關電晶體T1 402具有耦合掃描輸入205的閘極以及耦合資料輸入305的第一源極/漏極及耦合電容器Cs的第二源極/漏極。在一個實施例中,電壓位準掃描訊號賦能儲存電容器Cs 404充電,該儲存電容器Cs 404最終賦能電流流動至耦合輸出模組的LED裝置。在一個實施例中,輸入模組耦合包含驅動電晶體的輸出模組。在此實施例中,μC產生類似於主動矩陣顯示 器的2T1C電路的電路,但額外電路配置為可能的。在一個實施例中,輸入模組充電儲存模組220中的一或更多個電容器。代替一或更多個電容器或除一或更多個電容器以外,儲存模組220亦可包含數位儲存,及類比數位轉換器(analog-to-digital converter;ADC)430用於儲存類比輸入的數位表示。
