高穿透式 (HLT) 觸控面板
一般觸控式面板的透光度以全光譜的測試儀器或以光波長550nm 的儀器測量出來為78% – 81%,這是過去十幾年一般電阻式觸控面板產(chǎn)品規(guī)格。若放在某些亮度較低的LCD 面板前,或是在比較亮的環(huán)境中,往往造成使用者看不清楚LCD 螢?zāi)坏挠嵪ⅰ?br>AMT 高穿透式觸控面板(High Light Transmission, HLT) 可以讓光穿透度增高為85%,其原理是在ITO 玻璃與ITO 膜鍍上AR (Anti-Reflective) 層來增加光穿透度的效果,讓低照度的LCD 訊息可以被看清楚一點(diǎn)。而在高穿透率的觸控面板上依照不同的玻璃厚度及鍍的AR膜程度,可以決定光的穿透度。
高穿透式觸控面板其不同的光穿透度,使用不同厚度的玻璃,穿透率如下表:
Glass Thickness | Light Transmission Rate |
1.1 mm glass | 85% |
1.8 mm glass | 84.5% |
