產品敘述

WF0840ASWAMLNB0型號模組是具有廣溫、高亮度、廣視角等特性的TFT液晶模組,顯示器對角線尺寸為8.4吋,解析度1024x768 像素,搭載投射電容式觸控螢幕 (PCAP)。模組尺寸為199.5 x 149.0 mm;有效尺寸為170.8032 x 128.1024 mm。此模組使用支援LVDS介面的ST5821AH和ST5084AA驅動IC。LVDS 技術運用在 TFT 顯示器上越來越受歡迎,此技術適合需要高速數據傳輸的 TFT LCD 模組,它在提供高資料傳輸率的同時會有很低的功耗。搭載的PCAP觸控螢幕內建EXC81W32 IC支援介面為USB(I2C可用),支援2個觸控點。

WF0840ASWAMLNB0採用IPS面板技術(In-plane Switching)此面板技術可以解決視角問題讓顯示器視角更寬廣,模組視角可達左:80/ 右:80/ 上:80/ 下:80(典型值),具高亮度為800 nits(典型值),對比度為1000:1(典型值)。邏輯電源電壓(VDD)為3.0V~3.6V,典型值為3.3V。此型號為廣溫TFT工作溫度範圍-30℃~+80℃;儲存溫度範圍-30℃~+80℃。此8.4吋1024x768 TFT模組適合應用在戶外設備,自動販賣機、自動繳費機以及醫療設備、測試儀器等。
