射的光線,光線的亮度可能比典型光源所放射的光線亮度 為低,因此影像之亮度改善受到限制。 為了解決上述問題,韓國專利申請案號2〇〇3 —〇28〇9揭 露一種表面光源(背光元件)及一種使用該表面光源之液晶 顯示器組件。 第3圖所示為韓國專利申請案號2〇〇3-〇28〇9所揭露之 表面光源及液晶顯示器組件。如第3圖所示,發光燈泡31 (、例如:螢光燈或發光二極體)係安裝於導光板3〇之一侧, 並且裝设一個調光元件(未顯示)於導光板3〇上表面或下表 面之至少一個表面上,以便改變照射至導光板3 〇之上表面 或下表面之光線莖。此外,將增強發光薄膜3 2安裝在導光 板30上表面或下表面之至少一個表面上。如此,由發光燈 泡31所發射之光線可能藉由增強發光薄膜32而共振 (resonate),因而能夠改善光線亮度。 雖然圖中並無顯示,但是光調整元件具有之蝕刻表面 其狀態為··藉由穿過光調整元件而照射向導光板3〇上表面 光線之透射比會與照射向導光板3〇下表面光線之透射比不 同。尤其,光調整70件能與增強發光薄膜3 2 一體成型。如 第4圖所示,增強發光薄膜32包括:一個共振層41以及在 #振層與擴散薄膜兩者間塗佈黏著劑43將擴散薄膜貼附於 共振層41之上表面及下表面。 此外,擴散板被安裝於帶有增強發光薄膜3 2之導光板 3J的上表面及下表面’ &且將内液晶顯示器及外液晶顯示 器33及34分別安裝於擴散板上。
第7頁 .200538821 五、發明說明(4) 依據上述表面光源及具有相同表面光源之液晶顯示器 組件,能夠以包含光調整元件之增強發光薄膜來調整照射 於内液晶顯示器上之光線量使其與照射於外液晶顯示器上 之光線量不同。此外,能夠以包含光調整元件之增強發光 薄膜增強光線,因而能夠改善光線之亮度。 然而,上述表面光源及具有相同表面光源之液晶顯示 器組件顯現一個問題,因為使用增強發光薄膜將光線增強 至所需求之程度會受到限制。尤其是,因為圓偏振光 (Circularly Polarized Light)被傳送至内液晶顯示器及 外液晶顯示器’不易改善液晶顯示器組件之視角。 _【發明内容】 因此,本發明主要在解決前述習知技術所發生之問 題,並且本發明之目的在提供一種能夠改善雙向顯示器視 角及亮度之雙向顯示器。 為達成上述之目的,本發明提供一種雙向顯示器,包 括:一個發光燈泡、一個導光板安裝於發光燈泡之一側以 便導引由發光燈泡照射至導光板上表面及下表面之光線、 一個擴散板安裝於導光板之上表面及下表面以便均勻地擴 散由導光板所輸出之光線、一對稜鏡片(Prism sheet)形 #於每個擴散板上以便將擴散板輸出之光線偏振 (polarize)、以及將裝設在稜鏡片上之内液晶顯示器及外 液晶顯示器安裝於導光板之上表面及下表面以便藉由使用 偏振光來顯示預設之影像。 依據本發明之較佳具體實施例,該發光燈泡包括:一
