High Brightness Display 高亮面板

高亮面板 (High Brightness Display)液晶屏模組 三亞科技解析高亮度面板的構成及原理

高亮面板 介紹,眾所周知,液晶面板(TFT-LCD)是液晶顯示器的心臟,佔據了整個產品八成以上的成本,其品質會直接影響到顯示器的色彩、亮度、對比度、可視角度等等功能參數和顯示效果。但是,高亮度面板 (High Brightness) 的內部結構又是什麼樣的呢?這裡 三亞科技(3AScreen) 來做一個簡單介紹。 首先,我們先來瞭解一下顯示器的工作原理,簡單來說,顯示器的成像原理就是,通過施加電壓刺激液晶分子偏轉產生點、線、面的圖像,液晶分子便如閘門般地阻隔LED背光源發出光線的通過率,進而將光線投射在不同顏色的彩色濾光片中形成圖像。 液晶面板通常由液晶分子層、濾光膜和背光源等幾大部分組成,液晶分子層下方和金屬背板之間的構造中主要是反光板、折射板,還有三層的濾光膜。反光板的作用就是將光線反射回去,減少光線的損失。折射板的作用就是將光線在它的內部進行反射和折射,均勻的分佈在整個液晶螢幕中。濾光膜的作用就是除去某種波長的光線,三層的濾光膜均有自己的作用。在LED背光源中,除了發光源之外,與之配備的還有一層透明的濾光層和白色的反光板。其中濾光層上很多類似顆粒的東西,其目的是通過折射和反射,讓背光能夠更加均勻,而反光板則能夠增加LED背光源光線的亮度。   LED背光搭配上反光板、折射板和濾光膜,光源就可以比較均勻分佈在整個螢幕中,而目前很少有條形設計的LED背光源的光線能夠達到十分均勻分佈在整個螢幕,因此很多高端顯示器或者專業級顯示器採用了點陣式的LED背光源設計。
