1374309 九、發明說明 【發明所屬之技術領域】 本發明係關於光電裝置及電子機器，特別是關於直接 或者間接保持光電面板的保持體之至少一部份係以金屬板 構成的場合之適切的光電裝置的構成。 【先前技術】 φ 一般而言，作爲光電裝置之液晶顯示裝置，把液晶顯 示面板安裝於合成樹脂零件或金屬板所構成的框架者係屬 已知，透過此框架而把液晶顯示面板搭載於電子機器。作 爲框架，有由下方支撐液晶顯示面板的下框架或者支撐框 架（收容構件），與由觀察側保持液晶顯示面板的上框架 或者保持框架（安裝構件）：作爲液晶顯示裝置，藉由這 些之上下的框架而挾持著液晶顯示面板狀態之構成係屬已 知（例如，可以參照以下之專利文獻1及2 )。 Φ [專利文獻1]日本專利特開2〇〇5-99616號公報 [專利文獻2]日本專利特開2005 - 283826號公報 - 【發明內容】 [發明所欲解決之課題] 然而，近年來’行動電話或可攜式資訊終端等電子機 器對於小型化、薄型化的要求越來越強，其結果使得被搭 載於前述電子機器的前述液晶顯示裝置等之框架構造也不 得不薄型化，使得爲了確保耐衝擊性等之框架強度的維持 -4- 1374309 變得比較難達成。因此，框架構造越來越多使用由金屬板 所構成的金屬框。 然而，在使用由金屬板所構成的金屬框的場合也還是 扭轉不了薄型化與耐衝擊性兩個對立的要求的狀況，所以 伴隨著最近的光電裝置的薄型化的發展，即使使用金屬板 的場合也越來越難確保充分的剛性。 此外，在以金屬板構成的框架，例如切斷金屬板的一 • 部份或是折曲以形成卡合突起，或者是I受置卡合於其他構 件的卡合突起的卡合開口部等的場合相當多，因爲這樣的 卡合構造會使框架強度降低，所以確保充分的剛性變得越 來越難。 進而，以金屬板構成的保持體與以樹脂成型形成的樹 脂框架相比形狀上的限制很多，所以設計的自由度很低， 會有液晶顯示面板的保持功能、支撐功能、定位功能等難 以改善的問題點。 • 在此，本發明係爲了解決前述問題點，藉由改善框架 構造，而在不違反小型化、薄型化的要求下提供可以得到 充分強度的光電裝置。 [供解決課題之手段] 有鑑於相關的實際情況，本發明之光電裝置，特徵爲 ‘具備：光電面板、及直接或者間接保持該光電面板之保持 體；前述保持體之至少一部份以金屬板構成，該至少一部 份，具有由前述金屬板之基部折返而成的折返範圍，前述 -5- 1374309 折返範圍之先端形成段部，藉由該段部保持其他構件。 根據此發明，在保持體之以金屬板構成的部分，於該 金屬板被形成由基部折返而成的折返範圍，在此折返範圍 的先端與基部形成段部，藉由此段部保持其他構件，而在 兩者間設置屈折部的緣故可以提高該部分的剛性，同時以 折返範圍的先端與基部構成的段部的卡合強度，與金屬板 的厚度無關而可因應於折返範圍的長度而提高。進而，以 折返範圍的先端與基部形成段部，所以即使在金屬板不設 置缺口或開口也可以設置卡合構造，所以可以提高在金屬 板至少一部份構成的保持體的設計自由度。亦即，作爲光 電裝置的耐衝擊性可以確保而且可以因應於小型化、薄型 化的要求。 於本發明，較佳者爲前述其他構件，具有被保持於前 述保持體之第1被保持構件與第2被保持構件，前述第1被 保持構件藉由前述保持體之前述段部被保持於前述保持體 ，前述第2被保持構件藉由前述第1被保持構件保持著。在 此場合，作爲其他構件而使其爲具有第1被保持構件與第2 被保持構件的構成的場合，可以用一個段部保持第1被保 持構件與第2被保持構件。因此，可以容易組裝收容光電 面板的外殼構造。 於本發明，較佳者爲前述金屬板被配置於與前述光電 面板平面重疊的範圍之至少一部份，被設有由該至少一部 份屈折立起設置而被配置於前述光電面板的側方之側壁， 前述折返範圍於前述側壁構成前述段部。藉由構成在側壁 1374309 設置折返範圍的段部，可以提高側壁的剛性，同時其他構 件的保持也變得容易。 於本發明，前述其他構件由樹脂所形成，前述其他構 件以被一體成形於前述金屬板而成者較佳。藉由在側壁使 用金屬板可以提高機械強度以外，藉由在其他構件使用樹 脂可以使引起其他構件之彈性變形，可使構件更緊密地卡 合。 於本發明，前述金屬板，最好具備被一體成形於該金 屬板的外側之樹脂。藉由具備被一體成形於側壁外側的樹 脂可以提高收容構件的強度。 於本發明，以在對應於該保持體之前述段部的區域， 設置開口部較佳。藉由在對應於段部的區域設置開口部， 可以提高供產生對應於側壁的厚度份之配合餘地（margin) 之階差形狀或配置的自由度。 本發明之光電裝置，特徵爲具備：光電面板、收容前 述光電面板之具有底面與側壁之收容構件、被形成於前述 收容構件的側壁之段部、以及被配置於前述收容構件內而 被配置於前述段部與前述收容構件之底面之間的支撐前述 光電面板之支撐構件。 根據本發明，在段部與底面之間，被配置支撐光電面 板的支撐構件。因此，光電面板的位置，依照段部與底面 之配置而根本地被保持，與其他的固定手段相比光電面板 的定位精度可以提高。 於本發明，前述段部最好是折返前述側壁而形成。因 1374309 爲藉由折返側壁增加了側壁的實際厚度，所以可提高收容 構件的強度。 本發明之光電裝置，特徵爲具備：光電面板、由表面 背面之一方側收容前述光電面板之具有底面與側壁的收容 構件、由表面背面之另一方側收容安裝前述光電面板於前 述收容構件之具有底面與側壁之安裝構件、被形成於前述 收容構件的側壁或者前述收容構件的側壁與前述安裝構件 之間之至少一方的段部、以及被配置於前述收容構件內， 被配置於被形成於前述收容構件的側壁之段部或者被形成 於前述收容構件的側壁與前述安裝構件之間的段部與前述 收容構件的底面之間，支撐前述光電面板之支撐構件。 根據此發明，收容構件、安裝構件、支撐光電面板的 支撐構件係透過段部而被固定。因此，即使被施加應力的 場合也可以抑制前述構件的位置偏移。 於本發明，最好是段部被形成於前述收容構件，而在 前述收容構件的底面與前述段部之間，被配置前述安裝構 件之一部份與前述支撐構件。藉由在段部與底面之間配置 安裝構件之一部分與支撐構件，決定固定收容構件、安裝 構件、與支撐構件的位置關係，即使被施加應力的場合也 可以抑制前述構件的位置偏移。 於本發明，前述段部最好是折返前述側壁而形成。因 爲藉由折返側壁增加了側壁的實際厚度，所以可提高收容 構件的強度。 本發明之光電裝置，特徵爲具備：光電面板、由表面 1374309 背面之一方側收容前述光電面板之收容構件、被形成於前 述收容構件的側壁之段部、以及於前述段部與前述收容構 件之底面之間至少被配置一部份之，由前述光電面板之表 面背面之另一方側收容安裝於前述收容構件之安裝構件。 根據此發明’收容構件與安裝構件被直接卡合而固定 。此場合’收容構件與安裝構件不透過其他構件而直接卡 合，與包含其他構件使其卡合的場合相比，可以減少產生 尺寸誤差的餘地’即使加上外部擾亂因素也可以不鬆弛地 固定安裝構件與收容構件。 於本發明，前述段部最好是折返前述側壁而形成。因 爲藉由折返側壁增加了側壁的實際厚度，所以可提高收容 構件的強度。 接著，本發明之電子機器，特徵爲具備前述之任一所 記載之光電裝置，及該光電裝置之控制手段。作爲這樣的 電子機器，特別是適用於行動電話、可攜式資訊終端、車 載用顯示裝置等被要求小型化、薄型化者的場合，可以確 保高的耐衝擊性。 【實施方式】 〔第1実施形態〕 其次，參照附屬圖面詳細說明本發明之實施型態。圖 1係顯示相關於本實施型態之光電裝置（液晶顯示裝置） 100之槪略分解立體圖。此光電裝置100具備構成背光之照 明單元1 1 0、及被配置於該照明單元1 1 〇的前面側（觀察側 1374309 )之光電面板（液晶顯示面板）120，同時還具備具有作 爲收容這些的收容構件之支撐框架130、作爲支撐構件之 內側框架1 40、以及作爲安裝構件之保持框架丨5 0之保持體 〇 照明單元1 10具備：led (發光二極體）、以冷陰極 管等構成之光源Π1 '以及使由光源111放出的光由光入射 面（端面）112a導入而由光射出面（表面）112b射出之 導光板112。此處，於配線基板（可撓印刷電路板）113上 被實裝複數光源1Π，沿著前述光入射面112a的長邊方向 (與側壁1 1 3平行的方向）排列。此外，於導光板1 1 2的背 後被配置反射片114。進而，雖未圖示但光學片最好是被 配置於前述光射出面112b。此處，導光板11 2被構成爲平 面俯視矩形狀。 光電面板1 20，係由玻璃等所構成的透明基板1 2 1與 1 2 2被貼合，而於其間被配置未圖示之光電物質（液晶） 者。於基板121設有由基板122伸出之基板伸出部121T，於 此基板伸出部121T上被實裝驅動電路123或訊號輸入用之 配線基板（可撓印刷電路板）124。又，因應需要在基板 1 2 1、1 2 2的外面上被配置（貼附）偏光板1 26 (基板1 2 1側 之偏光板省略圖示）》光電面板121被構成爲平面俯視矩 形狀，其顯示區域120A也被構成爲矩形狀。 支撐框架13 0被構成爲平面俯視矩形狀，具有底面131 、立設於此底面1 3 1的側方之4個側壁1 3 2,1 3 3。側壁1 3 2被 設至3個於一邊開放之矩形狀，剩下的一個側壁1 3 3的上緣 -10- 1374309 被形成爲比其他的側壁1 3 2之上緣稍微低些，如後所述以 即使安裝於保持框架150的場合前述配線基板113、124之 導出口也被確保的方式構成。支擦框架130的內部被收容 有內側框架1 4 0，於此內側框架1 4 0之內側，被收容配置照 明單元110。此外，光電面板120因應必要中介著雙面膠帶 127等，被支撐於設在內側框架140的周圍的面板支撐面 140a 上。 保持框架150在圖示例的場合，以由上方覆蓋光電面 板120的方式被安裝。保持框架150被構成爲下部開口，而 可安裝於前述支撐框架130，於上部具備可由觀察側（圖 示上方）視覺確認光電面板12〇的顯示區域120A地構成之 顯示窗150a。保持框架150具備開口出顯示窗150a而成的 上面部151、及朝向比此上面部151的周圍更下方而被立起 設置的側壁152，1 53。保持框架150平面俯視爲矩形狀，被 構成爲對應於前述支撐框架130的平面形狀，亦即在圖示 例的場合比支撐框架130稍微小些，於支撐框架130的側壁 132，133的內側其側壁1 52,1 5 3被插入的尺寸》3個側壁152 與支撐框架130之側壁132對應被構成爲一邊開放的矩形狀 ，剩下的1個側壁1 5 3的下緣被形成爲比其他側壁1 5 2的下 緣更低，以於組裝狀態在與前述支撐框架〗3 0之側壁1 3 3的 上緣之間確保前述導出口的方式被構成。 (第1構成例）圖2係顯示前述實施型態之具體的第1 構成例之槪略部分剖面圖。本構成例之場合，作爲一例’ 設有供卡合固定支撐框架130與內側框架140之用的卡合構 -11 - 1374309 造。此卡合構造，例如圖2所示，被形成於支撐框架130的 側壁132的內面，與內側框架140的外周面之間。支撐框架 130的側壁132具有由底面131立設的基部132a、在設於此 基部132a的上端之屈折部132b被折返至內側，被重疊配 置於前述基部132a的內面上之折返範圍132c。此折返範 圍132c的先端被配置於基部13 2a的高度方向途中，此先 端之端面在基部132a的內側構成段部132d。 於內側框架140的外周面被形成突出部141，此突出部 141的上面構成段部141a。將內側框架140插入支撐框架 130的內部時，內側框架140的前述突出部141抵接於側壁 132的內面上的折返範圍132c，使側壁13 2稍微往外側變形 同時導入支撐框架130之內，藉由在被形成於此支撐框架 130的內部的前述段.部132d的下方收入段部141a，內側框 架140被段部13 2d與底面131挾持，被保持於支撐框架130 。接著，光電面板120被夾持於保持框架150之側壁152、 153與內側框架140之間。 在此圖2所示之例，可以用金屬板構成支撐框架130, 此外，可以用白色聚乙烯等合成樹脂構成內側框架140。 在此場合，主要藉由支撐框架130的彈性變形而可以得到 圖示的卡合狀態。但是，構成內側框架1 40的材料不限於 合成樹脂，例如亦能夠以與支撐框架1 3 0同樣的金屬板構 成。 在此例，使成爲支撐框架130的側壁132於上部具有屈 折部132b，而折返範圍132c重疊於基部132a的狀態’所 -12- 1374309 以可提高側壁1 3 2自身的剛性，同時段部丨3 2 d的剛性與金 屬板的厚度無關而因應於折返範圍132c之由屈折部132b 起至先端爲止的長度而增大，所以卡合強度也可以大幅提 高。進而’在折返範圍132c的先端被形成段部132d，所 以不需要在側壁132被形成卡合用開口部或缺口而且設置 被折曲形成的卡合片等，也沒有使側壁132的剛性降低之 虞。 (第2構成例）圖3係顯示相關於第2構成例之一例之 槪略部分剖面圖。在此構成例，如圖3所示，支撐框架130 與保持框架150直接卡合著。支撐框架13〇與圖2所示的場 合同樣以金屬板構成，同時使側壁1 3 2折返至內側以形成 屈折部132b，經此屈折部132b折返範圍132c重疊於基部 132a的內面上，該折返範圍132c之先端構成段部I32d。 另一方面’保持框架150雖未特別限定，在圖示例的場合 ’與支撐框架130同樣以金屬板構成。於保持框架15〇的側 壁152的下緣被形成往外側折曲的卡合突起152a，此卡合 突起152a的先端與前述段部132d卡合而被保持。又，亦 可以使此卡合突起152a，與前述段部132d同樣，使金屬 板在折曲部往外側折返，藉由將折曲部分重疊於基部的外 面上而形成的折返範圍的先端所構成的段部。 在本構成例，保持框架150不僅對支撐框架130被卡合 保持，保持框架150之前述卡合突起152a之折曲部i52b與 設於內側框架140的外周之突出部141的段部l4〗a抵接， 藉此內側框架140成爲對支撐框架130及保持框架15〇被卡 -13- 1374309 合保持的狀態。 在本構成例，以前述支撐框架1 3 0全體係以金屬板構 成爲前提而進行了說明，但是亦可係支撐框架130之一部 分以金屬板構成之，例如金屬板與合成樹脂被一體化者。 此外，在本構成例，係於支撐框架130被形成折返範圍 132c而被構成段部13 2d，但亦可將同樣的構造適用於內 側框架140或者保持框架150。適用於內側框架140的場合 φ ’能夠以以替代圖3而適用圖10所示的構造來對應。在此 場合，取代突出部141而以段部141a卡合。進而，在前述 卡合構造係藉由折返至側壁1 3 2的內側而形成折返範圍 1 3 2 c ’但是把折返範圍折返至外側，在側壁1 3 2的外面上 設置段部亦可。在折返至外側的場合，保持框架150係在 支撐框架1 3 0的外側被卡合，所以保持框架1 5 0在平面俯視 具有比支撐框架130更大的形狀，成爲以卡合突起152a朝 向內側的方式被構成。 Φ 此外，在本構成例於支撐框架130形成段部132d，在 段部132d保持其他構件，但段部I32d可以作爲保持種種 構件之用的保持構造來使用。例如，亦可使用於將光電面 板120的周緣部保持於支撐框架130的內部之用途。 此外，在本構成例，係爲使折返範圍1 3 2 c沿著支撐 框架130的側壁132的延伸方向（圍繞底面131的周圍的方 向）伸展的形狀。藉此，可以更爲提高側壁1 3 2的剛性同 時保持力也可以增強。此處，關於卡合階差的形成，僅將 折返範圍132c形成於側壁132的延長方向之—部分，或者 -14- 1374309 是在該延長方向的不同位置形成爲不同高度亦可。例如， 如圖4所示，相對於折返範圍132c所致之段部132d位於高 的位置’其他場所的段部132d’位於比此還低的位置。此 外’折返範圍13 2c的先端幾乎抵接於底面131而未被形成 段部的場所132d’也被設置。如此般段部i32d，132d，的位置 限定於局部，或者隨著場所而設於不同的位置的場合，也 因爲於側壁132的上部被設置屈折部這一點，與在基部存 在重疊的折返範圍1 32c這一點與前述相同，所以提高側 壁13 2的剛性同時卡合構造的強度也可以提高。 (第3構成例）圖8(a)，（b)係顯示其他之第3構成例之 槪略部分剖面圖。在此構成例，如圖8(a)所示，支撐框架 130與保持框架150直接卡合著。接著保持框架150之折曲 部152b與支撐框架130之底面131直接接觸。 支撐框架13 0與圖2所示的場合同樣以金屬板構成，同 時使側壁1 3 2折返至內側以形成屈折部1 3 2 b，經此屈折部 132b折返範圍132c重疊於基部132a的內面上，該折返範 圍（安裝區域）132c之先端構成段部I32d。另一方面， 保持框架150雖未特別限定，在圖示例的場合，與支撐框 架130同樣以金屬板構成。於保持框架150的側壁152的下 緣被形成往外側折曲的卡合突起1 5 2 a，此卡合突起1 5 2 a 的先端與前述段部132d卡合而被保持。接著，藉由折曲 部152b與支撐框架130的底面131直接接觸使得保持框架 150被保持於支撐框架130上。 此外，如圖8(b)所示，亦可替代在保持框架1 50的側 -15- 1374309 壁152的外側被折曲的卡合突起152a的構成，而改爲在保 持框架50的側壁152貼附金屬或樹脂形成階差，或於保持 框架150的側壁152形成將金屬或樹脂一體成形而形成階差 之階差區域154。因爲可以省略施加供形成折曲部15 2b之 用所必要的大的應力之步驟，所以可以抑制保持框架1 5 0 的變形。 此外，在本構成例，因爲保持框架150與支撐框架130 係被直接卡合固定，所以尺寸誤差的發生源很少，可以更 精密地定位。 在本構成例，以前述支撐框架130全體係以金屬板構 成爲前提而進行了說明，但是亦可係支撐框架130之一部 分以金屬板構成之，例如金屬板與合成樹脂被一體化者。 (變形例）在第1實施型態所記載之圖2、圖3之內側 框架140適於使用插入成形法來製作。藉由使用插入成形 法形成內側框架140，與使支撐框架130卡合於內側框架 140的場合相比，可以提高與內側框架140之密接性。因此 ，內側框架14〇可以做爲支撐框架130的補強材料而發揮功 能，可以提高被邀求薄型化的光電裝置100的強度。此外 ，如圖9 (a)所示，以插入成形法形成內側框架1 4 0，進而 於側壁1 3 2,1 3 3的外側形成外側樹脂部1 6 0亦可。圖9 (a)係 對圖2所示之構造形成外側樹脂部1 6 0者。此場合同樣，對 圖3所示的構造同樣可以設置外側樹脂部1 6 0。藉由設置外 側樹脂部1 6 0可以補強支撐框架1 3 0。又，設置外側樹脂部 1 60的場合具有內側框架140不是必須的，例如於圖9(b)所 -16- 1374309 示的構造以插入成形法配置外側樹脂部160亦可，於此場 合，也可以得到使對光電面板1 20施加的應力以外側樹脂 部160分散的效果。 [第2實施型態] 其次，參照圖5說明相關於本發明的第2實施型態 。在此實施型態的光電裝置，因爲具有與前述圖1所示的 全體構成相同的構成，所以同一部份賦予相同符號，省略 其說明。 如圖5所示，在本實施型態，由側壁132的基部132a 中介著屈折部l32b而被折返設置折返範圍l32c，折返範 圍132c的先端構成段部132d的這一點與第1實施型態相同 ，該段部1 32d的用法也如第1實施型態所說明的。 在本實施型態，以臨於折返範圍1 3 2c的先端之段部 132d的方式於基部132a被形成開口部132e。亦即，開口 部132e係以折返範圍132c的先端於平面上被配置於開口 範圍內的方式被構成。在圖示例，折返範圍132c的先端 被形成於與開口部1 3 2 e的上側之開口緣平面上一致的位 置。 在本實施型態，藉由在基部132a設置開口部i32e， 使段部132d的卡合深度不僅有折返範圍132c的厚度，可 以充分確保。因此，可以謀求卡合狀態的安定化或卡合構 造的設計自由度的增大。在圖5，設於保持框架1 50的側壁 152的卡合突起152a，卡合於折返範圍132c的先端與開口 1374309 部132e之開口緣層積而成的段部I32d，比圖3所示的構成 例的場合更能大幅確保卡合突起1 52a的卡合深度。亦即 ’卡合突起15 2a的卡合狀態可以確實保持更爲安定，同 時卡合突起152 a的形狀/尺寸的自由度也增大。 [電子機器] 最後，參照圖6及圖7，說明搭載相關於前述各實施型 態之光電裝置的電子機器之實施型態。此電子機器200， 係將前述光電裝置10 0搭載於顯示部而成之電子機器，圖6

路，此顯示控制電路決定光電裝置1 〇〇的顯示態樣。 又，於電子機器200，前述保持體之至少一部份可以 藉由被固定於電子機器200側的框架、電子機器200的筐體 自身來構成。如此一來，對顯示部202的開口形狀可以在 高精度整合的位置設定顯示畫面。 圖7係顯示電子機器之對光電裝置1〇〇之控制系（顯示 控制系）之全體構成之槪略構成圖。此處所示之電子機器

。此驅動電路123，如前所述以直接實裝於光電面板120的 電子零件所構成，但除了前述態樣以外，也可以藉由被形 成於光電面板120的基板表面上的電路圖案，或者，被導 電連接於光電面板120的電路基板、被實裝於前述配線基 板124等之其他電子零件上之半導體1C晶片或者電路圖案 等而構成。 顯不資訊輸出源291，具備：ROM (Read Only Memory )或RAM ( Random Access

Description of the Invention [Technical Field] The present invention relates to an optoelectronic device and an electronic device, and more particularly to a suitable optoelectronic device in which at least a portion of a holder for directly or indirectly maintaining a photovoltaic panel is formed of a metal plate. The composition of the device. [Prior Art] φ Generally, as a liquid crystal display device of a photovoltaic device, a liquid crystal display panel is mounted on a frame composed of a synthetic resin component or a metal plate, and the liquid crystal display panel is mounted on the electron through the frame. machine. As the frame, there are a lower frame or a support frame (accommodating member) that supports the liquid crystal display panel from below, and an upper frame or a holding frame (mounting member) that holds the liquid crystal display panel from the observation side: as a liquid crystal display device, by means of these The constitution of the state in which the liquid crystal display panel is held by the frame is known (for example, refer to Patent Documents 1 and 2 below). Φ [Patent Document 1] Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. No. Hei. No. 2005-283826. An electronic device such as a mobile phone or a portable information terminal is becoming more and more demanding for miniaturization and thinning, and as a result, the frame structure of the liquid crystal display device or the like mounted on the electronic device has to be reduced in thickness, so that It is difficult to achieve the maintenance of the frame strength of impact resistance, etc. -4- 1374309. Therefore, the frame construction is increasingly using a metal frame composed of a metal plate. However, when a metal frame made of a metal plate is used, the two opposite requirements of the reduction in thickness and impact resistance are not reversed. Therefore, with the recent development of thinning of photovoltaic devices, even metal plates are used. It is also increasingly difficult to ensure sufficient rigidity in the occasion. Further, in the frame made of a metal plate, for example, one portion of the metal plate is cut or bent to form an engaging projection, or the engaging opening portion of the engaging projection that is engaged with the other member is placed. There are quite a few occasions, because such a snap-fit structure will reduce the strength of the frame, so it becomes more and more difficult to ensure sufficient rigidity. Further, the holding body made of a metal plate has a much more limited shape than the resin frame formed by resin molding, so the degree of freedom in design is low, and the holding function, the supporting function, the positioning function, and the like of the liquid crystal display panel are difficult to be improved. The problem point. In order to solve the above problems, the present invention provides an electro-optical device capable of obtaining sufficient strength without compromising the miniaturization and thickness reduction by improving the frame structure. [Means for Solving the Problem] In view of the related actual situation, the photovoltaic device of the present invention is characterized by having: a photovoltaic panel, and a holder for directly or indirectly holding the photovoltaic panel; at least a part of the holder is made of metal The plate is configured such that at least a portion thereof has a folded-back range formed by folding back the base portion of the metal plate, and a tip end of the folding back range of the -5-37479 is formed as a segment portion, and the other portion is held by the segment portion. According to the invention, in the portion of the holding body formed of the metal plate, the metal plate is formed with a folding-back range formed by the base portion, and the tip end of the folding-back range forms a segment portion with the base portion, whereby the other members are retained by the segment portion However, the rigidity of the portion can be increased by providing the inflection portion therebetween, and the engagement strength between the tip portion of the folding end portion and the base portion can be made irrespective of the thickness of the metal plate depending on the length of the folding back range. improve. Further, since the tip end portion of the folding-back range forms a step portion with the base portion, the engagement structure can be provided even if the metal plate is not provided with a notch or an opening, so that the degree of freedom in designing the holder formed of at least a part of the metal plate can be improved. That is, the impact resistance of the photovoltaic device can be ensured and can be made to meet the requirements of miniaturization and thinning. In the above-described other members, the first member to be held and the second member to be held are preferably held by the holder, and the first member to be held is held by the step of the holder. In the above-described holding body, the second held member is held by the first held member. In this case, when the first member to be held and the second member to be held are configured as the other members, the first member to be held and the second member to be held can be held by one step. Therefore, the outer casing structure accommodating the photovoltaic panel can be easily assembled.

By forming the section where the folded-back range is provided on the side wall 1374309, the rigidity of the side wall can be improved while the maintenance of other members becomes easy. In the present invention, the other member is formed of a resin, and the other members are preferably integrally formed on the metal plate. In addition to the mechanical strength can be improved by using a metal plate on the side wall, the member can be more tightly engaged by causing elastic deformation of other members by using a resin in other members. In the invention, it is preferable that the metal plate has a resin integrally formed on the outer side of the metal plate. The strength of the housing member can be improved by providing the resin integrally formed on the outer side of the side wall. In the present invention, it is preferable to provide an opening portion in a region corresponding to the above-mentioned segment portion of the holding body. By providing the opening portion in the region corresponding to the segment portion, it is possible to increase the degree of freedom in the step shape or arrangement for generating the margin of the thickness portion corresponding to the side wall. An optoelectronic device according to the present invention includes: a photovoltaic panel; a housing member having a bottom surface and a side wall that accommodates the photovoltaic panel; a segment formed on a side wall of the housing member; and is disposed in the housing member and disposed A supporting member for supporting the photovoltaic panel between the segment and the bottom surface of the receiving member. According to the invention, a support member for supporting the photovoltaic panel is disposed between the segment and the bottom surface. Therefore, the position of the photovoltaic panel is fundamentally maintained in accordance with the arrangement of the segment and the bottom surface, and the positioning accuracy of the photovoltaic panel can be improved as compared with other fixing means. In the present invention, the segment is preferably formed by folding back the side wall. Since 1374309 increases the actual thickness of the side wall by folding back the side wall, the strength of the receiving member can be increased. An optoelectronic device according to the present invention is characterized in that it includes a photoelectric panel, a housing member having a bottom surface and a side wall of the photovoltaic panel, and one side of the front and back surfaces, and the photoelectric panel is housed in the housing member on the other side of the front and back surfaces. a mounting member of the bottom surface and the side wall, at least one of a side wall formed between the side wall of the accommodating member, a side wall of the accommodating member, and the mounting member, and a partition portion disposed in the accommodating member are disposed in the front side A segment of the side wall of the accommodating member or a support member formed on the photovoltaic panel between the segment formed between the side wall of the accommodating member and the mounting member and the bottom surface of the accommodating member. According to the invention, the accommodating member, the mounting member, and the supporting member supporting the photovoltaic panel are fixed by the segment portion. Therefore, the positional deviation of the aforementioned members can be suppressed even when stress is applied. In the invention, it is preferable that the segment portion is formed in the accommodating member, and one of the mounting members and the support member are disposed between the bottom surface of the accommodating member and the segment portion. The positional relationship between the fixed receiving member, the mounting member, and the supporting member is determined by arranging one of the mounting members and the supporting member between the segment portion and the bottom surface, and the positional displacement of the member can be suppressed even when stress is applied. In the present invention, the segment is preferably formed by folding back the side wall. Since the actual thickness of the side wall is increased by folding back the side wall, the strength of the housing member can be improved.

In this case, the accommodating member and the attachment member can be directly engaged without passing through other members, and the space for occurrence of dimensional error can be reduced as compared with the case where the other member is engaged with the other member, and the external disturbance can be fixed without looseness. The mounting member and the receiving member. In the present invention, the segment is preferably formed by folding back the side wall. Since the actual thickness of the side wall is increased by folding back the side wall, the strength of the housing member can be improved.

[Embodiment] [First embodiment] Next, an embodiment of the present invention will be described in detail with reference to the attached drawings. Fig. 1 is a schematic exploded perspective view showing a photovoltaic device (liquid crystal display device) 100 according to the present embodiment. The photovoltaic device 100 includes a lighting unit 110 that constitutes a backlight, and a photovoltaic panel (liquid crystal display panel) 120 that is disposed on the front side (observation side 1374309) of the illumination unit 1 1 ,, and also has a storage unit a support frame 130 for accommodating members, an inner frame 140 as a support member, and a holding body 保持50 for holding the frame 作为50 as a mounting member. The illumination unit 110 is provided with a led (light emitting diode) and a cold cathode tube. The light source Π1' and the light guide plate 112 that introduces the light emitted from the light source 111 from the light incident surface (end surface) 112a and is emitted from the light exit surface (surface) 112b. Here, a plurality of light sources 1 实 are mounted on the wiring board (flexible printed circuit board) 113, and are arranged along the longitudinal direction of the light incident surface 112a (direction parallel to the side walls 1 1 3). Further, a reflection sheet 114 is disposed behind the light guide plate 112. Further, although not shown, the optical sheet is preferably disposed on the light exit surface 112b. Here, the light guide plate 11 2 is formed in a rectangular shape in plan view. The photovoltaic panel 1 20 is bonded to a transparent substrate 1 2 1 and 1 2 2 made of glass or the like, and a photoelectric substance (liquid crystal) (not shown) is disposed therebetween. A substrate extending portion 121T extending from the substrate 122 is provided on the substrate 121, and a driving circuit 123 or a wiring substrate (flexible printed circuit board) 124 for signal input is mounted on the substrate extending portion 121T. Further, the polarizing plate 1 26 is disposed (attached) on the outer surfaces of the substrates 1 2 1 and 1 2 2 (the polarizing plate on the side of the substrate 1 2 1 is omitted). The photovoltaic panel 121 is formed in a rectangular shape in plan view. The display area 120A is also formed in a rectangular shape. The support frame 130 is formed in a plan view in a rectangular shape, and has a bottom surface 131 and four side walls 1 3 2 and 1 3 3 which are erected on the side of the bottom surface 133. The side wall 133 is provided to three rectangular shapes which are open on one side, and the upper edge -10- 1374309 of the remaining one side wall 133 is formed to be slightly lower than the upper edges of the other side walls 133, as after In the case where the holding frame 150 is attached to the holding frame 150, the outlets of the wiring boards 113 and 124 are secured. The inside of the squeegee frame 130 is housed with an inner frame 1400, and the inner side of the inner frame 1400 is housed and arranged with the illumination unit 110. Further, the photovoltaic panel 120 is supported by a double-sided tape 127 or the like as needed, and is supported by a panel supporting surface 140a provided around the inner frame 140. In the case of the illustrated example, the holding frame 150 is attached so as to cover the photovoltaic panel 120 from above. The holding frame 150 is configured as a lower opening, and is attached to the support frame 130, and has a display window 150a which is formed on the upper side (the upper side of the drawing) to visually confirm the display area 120A of the photovoltaic panel 12A. The holding frame 150 includes an upper surface portion 151 that opens out of the display window 150a, and side walls 152, 153 that are raised toward the lower side than the upper surface of the upper surface portion 151. The holding frame 150 is rectangular in plan view and is configured to correspond to the planar shape of the support frame 130, that is, slightly smaller than the support frame 130 in the example of the figure, on the inner side of the side walls 132, 133 of the support frame 130. The size of the side wall 1 52, 1 5 3 is inserted. The three side walls 152 are formed in a rectangular shape with one side open corresponding to the side wall 132 of the support frame 130, and the lower edge of the remaining one side wall 153 is formed to be larger than the other. The lower edge of the side wall 152 is lower, so that the assembled state is configured to ensure the aforementioned outlet between the upper edge of the side wall 133 of the support frame 1300. (First configuration example) Fig. 2 is a schematic partial cross-sectional view showing a specific first configuration example of the above-described embodiment. In the case of this configuration example, as an example, an engaging structure -11 - 1374309 for engaging and fixing the support frame 130 and the inner frame 140 is provided. This engagement structure, for example, as shown in Fig. 2, is formed between the inner surface of the side wall 132 of the support frame 130 and the outer circumferential surface of the inner frame 140. The side wall 132 of the support frame 130 has a base portion 132a that is erected from the bottom surface 131, and a folded-back portion 132c that is folded back to the inner side of the bent portion 132b provided at the upper end of the base portion 132a and that is overlapped and disposed on the inner surface of the base portion 132a. The leading end of the folded-back range 132c is disposed in the middle of the height direction of the base portion 13 2a, and the end surface of the leading end constitutes the segment portion 132d on the inner side of the base portion 132a. A protruding portion 141 is formed on the outer peripheral surface of the inner frame 140, and the upper surface of the protruding portion 141 constitutes a segment portion 141a. When the inner frame 140 is inserted into the inner side of the support frame 130, the protruding portion 141 of the inner frame 140 abuts against the folded-back range 132c on the inner surface of the side wall 132, and the side wall 13 2 is slightly deformed outward while being introduced into the support frame 130. The inner frame 140 is held by the segment 13 2d and the bottom surface 131 by the segment portion 141a below the aforementioned segment portion 132d formed inside the support frame 130, and is held by the support frame 130. Next, the photovoltaic panel 120 is sandwiched between the side walls 152, 153 of the holding frame 150 and the inner frame 140. In the example shown in Fig. 2, the support frame 130 may be formed of a metal plate, and the inner frame 140 may be formed of a synthetic resin such as white polyethylene. In this case, the illustrated engagement state can be obtained mainly by the elastic deformation of the support frame 130. However, the material constituting the inner frame 1400 is not limited to the synthetic resin, and can be formed, for example, by the same metal plate as the support frame 130. In this example, the side wall 132 which becomes the support frame 130 has the inflection portion 132b at the upper portion, and the folded-back range 132c overlaps the state of the base portion 132a -12 - 1374309 to increase the rigidity of the side wall 1 3 2 itself, and the section 丨The rigidity of 3 2 d is increased irrespective of the thickness of the metal plate, and the length of the folded-back region 132c increases from the bent portion 132b to the tip end, so that the engagement strength can be greatly improved. Further, since the segment portion 132d is formed at the tip end of the folding-back region 132c, it is not necessary to form the engaging opening portion or the notch in the side wall 132, and the engaging piece or the like which is formed by bending is not provided, and the rigidity of the side wall 132 is not lowered. . (Second Configuration Example) Fig. 3 is a schematic cross-sectional view showing an outline of an example of a second configuration example. In this configuration example, as shown in FIG. 3, the support frame 130 is directly engaged with the holding frame 150. The support frame 13A is formed of a metal plate as in the case shown in Fig. 2, and the side wall 133 is folded back to the inner side to form a folded portion 132b, and the folded portion 132b is folded over the inner surface of the base portion 132a. The leading end of the folded-back range 132c constitutes the segment I32d. On the other hand, the holding frame 150 is not particularly limited, and is exemplified by a metal plate in the same manner as the support frame 130. The lower edge of the side wall 152 of the holding frame 15 is formed with an engaging projection 152a which is bent outward, and the leading end of the engaging projection 152a is engaged with the above-mentioned segment 132d to be held. Further, similarly to the step portion 132d, the engaging projection 152a may be formed by folding the metal plate outward at the bent portion and by folding the bent portion over the outer surface of the base portion. Segment. In the present configuration example, the holding frame 150 not only engages and holds the support frame 130, but also the bent portion i52b of the engaging projection 152a of the holding frame 150 and the segment portion 144a of the protruding portion 141 provided on the outer periphery of the inner frame 140. When the inner frame 140 is abutted, the inner frame 140 is held by the support frame 130 and the holding frame 15 by the card-13-1374309. In the present configuration example, the entire structure of the support frame 130 is assumed to be a metal plate. However, one of the support frames 130 may be formed of a metal plate, for example, a metal plate and a synthetic resin are integrated. . Further, in the present configuration, the support frame 130 is formed with the folded portion 132c and the segment portion 13 2d is formed. However, the same structure may be applied to the inner frame 140 or the holding frame 150. When applied to the inner frame 140, φ ' can correspond to the configuration shown in Fig. 10 instead of Fig. 3. In this case, instead of the protruding portion 141, the segment portion 141a is engaged. Further, in the above-described engagement structure, the folded-back range 1 3 2 c ' is formed by folding back to the inner side of the side wall 133, but the folded-back range is folded back to the outside, and the step portion may be provided on the outer surface of the side wall 133. When the outer frame is folded back to the outer side, the holding frame 150 is engaged with the outer side of the support frame 130, so that the holding frame 150 has a larger shape than the support frame 130 in plan view, and the inner side of the engaging projection 152a is oriented inward. The way is constructed. Φ Further, in the present configuration example, the segment portion 132d is formed in the support frame 130, and the other members are held in the segment portion 132d. However, the segment portion I32d can be used as a holding structure for holding various members. For example, it can also be used for holding the peripheral edge portion of the photovoltaic panel 120 inside the support frame 130. Further, in the present configuration example, the folding-back range 1 3 2 c is extended along the extending direction of the side wall 132 of the support frame 130 (the direction around the circumference of the bottom surface 131). Thereby, the rigidity of the side wall 133 can be further increased and the holding force can be enhanced. Here, regarding the formation of the engagement step, only the folded-back range 132c is formed in a portion in the extending direction of the side wall 132, or -14-1374309 may be formed at different heights at different positions in the extending direction. For example, as shown in Fig. 4, the segment portion 132d with respect to the folded-back range 132c is located at a high position. The segment portion 132d' of the other location is located at a position lower than this. Further, the front end of the 'returning range 13 2c is also abutted against the bottom surface 131 and the portion 132d' where the segment portion is not formed is also provided. The position of the segments i32d, 132d is limited to a local portion, or is set to a different position depending on the location, and the folding portion of the upper portion of the side wall 132 is provided with a folding portion 1 overlapping with the base portion. This is the same as the above, so that the rigidity of the side wall 13 2 is increased and the strength of the engagement structure can be improved. (Third Configuration Example) Figs. 8(a) and 8(b) are schematic cross-sectional views showing the third configuration example. In this configuration example, as shown in Fig. 8(a), the support frame 130 is directly engaged with the holding frame 150. The bent portion 152b of the holding frame 150 is then brought into direct contact with the bottom surface 131 of the support frame 130. Similarly to the case shown in Fig. 2, the support frame 130 is formed of a metal plate, and the side wall 133 is folded back to the inner side to form a bent portion 1 3 2 b, and the folded portion 132b is folded over the inner surface of the base portion 132a. The tip end of the turn-back range (mounting area) 132c constitutes the segment portion I32d. On the other hand, the holding frame 150 is not particularly limited, and in the case of the illustrated example, it is formed of a metal plate similarly to the support frame 130. The lower end of the side wall 152 of the holding frame 150 is formed with an engaging projection 15 2 a that is bent outward, and the leading end of the engaging projection 1 5 2 a is engaged with the step 132d and held. Next, the holding frame 150 is held on the support frame 130 by the direct contact of the bent portion 152b with the bottom surface 131 of the support frame 130. Further, as shown in FIG. 8(b), instead of the configuration of the engaging projection 152a which is bent outside the side -15 - 1374309 wall 152 of the holding frame 150, the side wall 152 of the holding frame 50 may be replaced. The metal or resin is attached to form a step, or the side wall 152 of the holding frame 150 is formed with a stepped region 154 in which a metal or a resin is integrally formed to form a step. Since the step of applying a large stress necessary for forming the bent portion 15 2b can be omitted, the deformation of the holding frame 150 can be suppressed. Further, in the present configuration example, since the holding frame 150 and the support frame 130 are directly engaged and fixed, the source of the dimensional error is small, and the positioning can be performed more precisely. In the present configuration example, the entire structure of the support frame 130 is described as a metal plate structure. However, one of the support frames 130 may be formed of a metal plate. For example, the metal plate and the synthetic resin are integrated. (Modification) The inner frame 140 of Figs. 2 and 3 described in the first embodiment is suitably produced by an insert molding method. By forming the inner frame 140 by the insert molding method, the adhesion to the inner frame 140 can be improved as compared with the case where the support frame 130 is engaged with the inner frame 140. Therefore, the inner frame 14A can function as a reinforcing material for the support frame 130, and the strength of the photovoltaic device 100 which is invited to be thinned can be improved. Further, as shown in Fig. 9 (a), the inner frame 1 400 is formed by insert molding, and the outer resin portion 1 60 may be formed outside the side walls 1 3 2, 1 3 3 . Fig. 9 (a) shows the outer resin portion 160 formed in the structure shown in Fig. 2. Also in this case, the outer resin portion 160 can be provided similarly to the structure shown in Fig. 3. The support frame 130 can be reinforced by providing the outer resin portion 160. Further, when the outer resin portion 1 60 is provided, it is not necessary to have the inner frame 140. For example, the outer resin portion 160 may be disposed by insert molding in the structure shown in Fig. 9(b)-16-1374309.
