Description

顯示裝置
本發明係關於一種顯示裝置，更詳細而言，本發明係關於一種利用雙凸方式之三維顯示裝置。
作為不使用眼鏡之三維圖像顯示方式之一種，已知雙凸方式及視差屏障方式。所謂視差屏障方式，係指於所謂視差屏障之存在複數個縱向之細微狹縫之板之後方，設置有將來自右眼視野之圖像及來自左眼視野之圖像豎直地分割成帶狀並使其交替排列融合所成之圖像，藉由隔著配置於前方之視差屏障觀看該圖像，可對右眼與左眼提交不同圖像，從而顯示三維圖像。
另一方面，所謂雙凸方式，係指設置朝所謂雙凸透鏡之縱向延伸之半圓筒型之透鏡橫向排列所成者以取代視差屏障，藉由隔著雙凸透鏡觀看圖像，可對右眼與左眼提供不同圖像，從而顯示三維圖像。
日本專利特表2009-520231號公報揭示有利用液晶透鏡實現雙凸透鏡而顯示三維圖像之例。
圖13及圖14係對用於說明液晶透鏡610之原理之三維圖像顯示面板600進行顯示之圖。如圖13及圖14所示，液晶透鏡610係配置於液晶顯示裝置等顯示裝置620之顯示面上。液晶透鏡610具有：兩個玻璃基板611及615；包含密封於該等玻璃基板之間之液晶組合物之液晶層613；自液晶層613觀察時係跨越整個畫面而同樣地形成於顯示裝置 620側之相反側之玻璃基板611之透明電極，即面狀電極612；帶狀地形成於顯示裝置620側之玻璃基板615，且排列於顯示裝置之每兩個像素之透明電極，即帶狀電極614。
圖13顯示有二維顯示時之液晶透鏡610之液晶組合物之配向情況；面狀電極612與帶狀電極614為相同電位，液晶組合物之配向就液晶層613全體而言，皆為同一方向(平行配向)。藉由使該方向與自顯示裝置620出射之光之偏光方向一致，自顯示裝置620出射之光可於保持原偏光方向不變之情形下透過液晶透鏡610，從而可直接觀看顯示於顯示裝置620之二維圖像。即，自顯示裝置620之像素631及632發出之光分別被兩眼看到。
圖14係顯示三維顯示時之液晶透鏡610之液晶組合物之配向情況之圖，其揭示一面依照反相驅動週期變換極性，一面對面狀電極612及帶狀電極614施加不同電壓。如該圖所示般，由於面狀電極612與帶狀電極614之形狀之不同，而於液晶層中產生二維時為放射狀而三維時為圓柱狀之電場，藉由使液晶組合物沿著該電場進行配向，可形成雙凸透鏡，從而可實現三維顯示。即，如該圖所示，由像素631發出之光係被右眼看到，而由像素632發出之光係被左眼看到。
此處，將三維顯示時右眼用圖像進入左眼，或左眼用圖像進入右眼之現象稱作串擾，該串擾之比率越大，則三維顯示之顯示品質將越低。根據發明者等人之研究，可知，於圖14之構成中，如以L1及L3表示之光或以L2及L4表示之光般透過帶狀電極614之光所引起之串擾較大。該帶狀電極614上之液晶組合物在面狀電極612與帶狀電極614之電場之作用下，其長軸方向朝向液晶層613之厚度方向，導致透鏡效應幾乎消失殆盡，由於透過該部分之光並未受到來自透鏡之方向控制，而朝任意方向出射，而成為串擾之較大要因。
本發明係鑒於上述情形而完成者，其目的在於提供一種降低可 利用液晶透鏡進行三維顯示之顯示裝置之串擾之顯示裝置。
本發明係一種顯示裝置，其特徵在於包含：顯示面板，其具有配置成矩陣狀之複數個像素，且顯示圖像；液晶透鏡面板，其配置於上述顯示面板上，藉由切換而形成雙凸透鏡；及偏光板，其於上述液晶透鏡面板上，配置於與顯示面板相反側；上述液晶透鏡面板具備：液晶層，其具有液晶組合物；第1絕緣基板，其配置於上述液晶層之上述顯示面板側；第2絕緣基板，其配置於上述液晶層之上述偏光板側，具有與上述第1絕緣基板之配向膜之摩擦方向正交之摩擦方向之配向膜；帶狀電極，其係於上述第1絕緣基板及上述第2絕緣基板之任一者上，以朝一方向延伸之帶狀導電膜並排設置有複數個；且上述偏光板之偏光軸係與上述第2絕緣基板之配向膜之摩擦方向相同。
又，本發明之顯示裝置更包含面狀電極，該面狀電極係於上述第1絕緣基板及上述第2絕緣基板之任一另一者上，跨及整個顯示面而同樣地形成之導電膜。
又，於本發明之顯示裝置中，亦可為上述帶狀電極係形成於上述第1絕緣基板上之第1帶狀電極，且該顯示裝置更包含於上述第2絕緣基板上以朝與上述一方向正交之方向延伸之帶狀導電膜並排設置有複數個之第2帶狀電極。
又，於本發明之顯示裝置中，各帶狀電極亦可空開兩個像素份之間隔而並排配置。

以下，一面參照圖式，一面對本發明之第1實施形態及第2實施形態進行說明。另，於圖式中，對相同或同等要素附加相同之符號，而省略重複之說明。
[第1實施形態]
圖1概略性顯示本發明之第1實施形態之三維顯示裝置100。如該圖所示，三維顯示裝置100係由以夾於上框架110及下框架120間之方式固定之液晶模組130及未圖示之電源裝置等構成。
圖2中顯示液晶模組130之構成。液晶模組130包含：顯示面板即液晶顯示面板131，其藉由影像信號之輸入，使與影像信號之圖像對應之光透過而顯示二維圖像；背光單元132，其照射透過液晶顯示面板131之光；及液晶透鏡面板200，其為了在透過液晶顯示面板131後之光所形成之圖像上形成視差，藉由控制內部之液晶組合物之配向而可作為透鏡發揮功能；液晶顯示面板131與背光單元132構成進行通常之二維顯示之液晶顯示裝置135，液晶顯示面板131與液晶透鏡面板200係藉接著層133而接著。
另，於本實施形態中，雖將液晶顯示裝置135用作為顯示裝置，但亦可為不使用液晶之方式之有機EL顯示裝置、場發射顯示裝置(FED)等顯示裝置。
圖3係用於說明圖2之液晶透鏡面板200之電極配置之俯視圖。如該圖所示液晶透鏡面板200具有：遍布於顯示區域整體之導電圖案即面狀電極213；複數個帶狀導電圖案即帶狀電極215；用於對面狀電極213施加電位之端子208；及用於對帶狀電極215施加電位之端子206。
圖4係顯示圖3之IV-IV線之剖面之圖。如該圖所示，液晶透鏡面板200具有：液晶層214，其包含根據電場而改變配向之液晶組合物；玻璃基板(第1絕緣基板)216，其較液晶層214配置於更靠液晶顯示裝置135側，且形成有帶狀電極215；玻璃基板(第2絕緣基板)212，其自液晶層214觀察時係配置於與液晶顯示裝置135側相反側，且形成有面狀電極213；及偏光板211，其係配置於玻璃基板212之與液晶顯示裝置135側相反側。
此處，圖中之液晶顯示裝置135顯示有包含R(紅)G(綠)B(藍)三色且鄰接之像素141及142；帶狀電極215係空開兩個像素份之間隔而配置。另，帶狀電極215及面狀電極213亦可分別配置於作為相反側之玻璃基板之玻璃基板212及216。
此處，P1表示自液晶顯示裝置135出射之光之偏光方向，即液晶顯示裝置135之上偏光板之偏光方向；R1表示形成於玻璃基板216上之配向膜之摩擦方向。如該圖所示，偏光方向P1與摩擦方向R1一致。
又，P2表示偏光板211之偏光方向、R2表示形成於玻璃基板212上之配向膜之摩擦方向。偏光方向P2與摩擦方向R2一致，其方向為與偏光方向P1及摩擦方向R1之方向正交之方向。在該圖4中，經由端子206及208對面狀電極213及帶狀電極215施加有相同電位；由於液晶層214之液晶組合物係根據配向膜之摩擦方向而進行配向，故其於液晶層214內成為扭轉狀態。
圖5係就對面狀電極213及帶狀電極215施加有不同電位(交流電壓)之情形時之光之行進方向予以概略性顯示之圖。藉由施加不同電位，於液晶層214形成液晶透鏡，使自像素141發出之光到達右眼，自像素142發出之光到達左眼。此時，因靠液晶顯示裝置135之側之玻璃基板216之帶狀電極215上之液晶係朝液晶層214之厚度方向進行配向，故並未發揮出透鏡效應，而且，由於並未因液晶層214而進行旋光，自液晶顯示裝置135出射之光將維持原偏光。維持偏光而透過帶狀電極215上附近之光將被具有與自液晶顯示裝置135出射之時點之偏光方向P1垂直之偏光方向P2之偏光板211吸收。
因此，如上述般由於本實施形態之三維顯示裝置可屏蔽三維顯示時成為串擾原因之透過帶狀電極215上附近之光，從而可進行更清晰之三維顯示。
[第2實施形態]
對本發明之第2實施形態之可切換縱型顯示(直式)及橫型顯示(橫式)之三維顯示裝置進行說明。此處，因第2實施形態之三維顯示裝置之構成係與第1實施形態之三維顯示裝置之圖1及圖2之構成相同，故 省略重複之說明。
圖6係用於說明可切換進行縱型顯示及橫型顯示之液晶透鏡面板300之電極配置之俯視圖。如該圖所示液晶透鏡面板300具有：帶狀電極315，其於後述之下側玻璃基板301形成有複數個；平板狀電極316，其與帶狀電極315同層，且形成於各帶狀電極315之間；帶狀電極317，其形成於後述之上側玻璃基板302；平板狀電極318，其與帶狀電極317同層，且形成於各帶狀電極317之間；端子321，其用於對帶狀電極315施加電位；端子323，其用於對平板狀電極316施加電位；端子322，其用於對帶狀電極317施加電位；及端子324，其用於對平板狀電極318施加電位。
圖7係顯示圖6之VII-VII線之剖面之圖。如該圖所示，液晶透鏡面板300具有：液晶層304，其包含根據電場而改變配向之液晶組合物；絕緣基板即下側玻璃基板301，其較液晶層304配置於更靠液晶顯示裝置135側，且形成有帶狀電極315及平板狀電極316；絕緣基板即上側玻璃基板302，其自液晶層214觀察時係配置於與液晶顯示裝置135側相反側，且形成有帶狀電極317及平板狀電極318；及偏光板303，其係配置於上側玻璃基板302之與液晶顯示裝置135側相反側。
此處，P1表示自液晶顯示裝置135出射之光之偏光方向，即液晶顯示裝置135之上偏光板之偏光方向；R1表示形成於下側玻璃基板301上之配向膜之摩擦方向。如該圖所示，偏光方向P1與摩擦方向R1一致。
又，P2表示偏光板303之偏光方向、R2表示形成於上側玻璃基板302上之配向膜之摩擦方向。偏光方向P2與摩擦方向R2一致，其方向為與偏光方向P1及摩擦方向R1之方向正交之方向。在該圖7中，對帶狀電極315、平板狀電極316、帶狀電極317及平板狀電極318施加有相同電位；由於液晶層304之液晶組合物係根據配向膜之摩擦方向而配 向，故於液晶層304內成為扭轉狀態。
圖8係對與圖7相同之剖面中，以橫型顯示進行三維顯示之情形時之液晶組合物之配向情況予以概略性顯示之圖。該情形時，對帶狀電極315與其他電極，即平板狀電極316，帶狀電極317及平板狀電極318施加有不同電位(交流電壓)。圖9顯示有被施加至各個電極之交流電壓之時序圖。如該等之圖所示，藉由僅對帶狀電極315施加不同電位，而於液晶層304形成液晶透鏡，從而可如實施形態1之圖5所示般地進行三維顯示。此時，因帶狀電極315上附近之液晶係朝液晶層304之厚度方向進行配向，故並未發揮出透鏡效應，而且，因並未於液晶層304產生旋光，故自液晶顯示裝置135出射之光將維持原偏光。維持偏光而透過帶狀電極315上附近且偏光方向為P1之光將被具有與P1垂直之偏光軸方向P2之偏光板303吸收。藉此，可屏蔽成為串擾原因之透過帶狀電極315上附近之光。
圖10係表示圖6之X-X線之剖面之圖。在該圖中，對帶狀電極315、平板狀電極316、帶狀電極317及平板狀電極318施加有同電位；其與圖7僅剖面方向有所不同。
圖11係對與圖10相同之剖面中，以縱型顯示進行三維顯示之情形時之液晶組合物之配向情況予以概略性顯示之圖。該情形時，對帶狀電極317與其他電極，即帶狀電極315、平板狀電極316及平板狀電極318施加有不同電位(交流電壓)。圖12顯示有被施加至各個電極之交流電壓之時序圖。如該等之圖所示，藉由僅對帶狀電極317施加不同電位，而於液晶層304形成液晶透鏡，從而可如實施形態1之圖5所示般地進行三維顯示。此時，因帶狀電極317上附近之液晶係朝液晶層304之厚度方向進行配向，故並未發揮出透鏡效應，而且，因並未於液晶層304產生旋光，故自液晶顯示裝置135出射之光將維持原偏光。維持偏光而透過帶狀電極317上附近且偏光方向為P1之光將被具有與 P1垂直之偏光軸方向P2之偏光板303吸收。藉此，可屏蔽成為串擾原因之透過帶狀電極317上附近之光。
因此，如上述般由於本實施形態之三維顯示裝置可屏蔽三維顯示時成為串擾原因之透過帶狀電極315或317上附近之光，從而可進行更清晰之三維顯示。
雖然已描述當前被視為本發明之特定實施例之內容，但是應瞭解可對其作出多種修改，且希望隨附申請專利範圍涵蓋所有此等修改，如同此等修改落在本發明之真實精神及範疇內一般。
