HM185WX1-400 panel datasheet


The HM185WX1-400 is a color active matrix TFT LCD module using amorphous silicon TFT’s (Thin Film Transistors) as an active switching devices. This module has a 18.5 inch diagonally measured active area with diagonally measured active area with WXGA resolutions ( resolutions (1366 horizontal by horizontal by 768 vertical vertical pixel array). Each pixel is divided into RED, GREEN, BLUE dots which are arranged in vertical stripe and this module can display 16.7M colors. The TFT-LCD panel used for this module is adapted for a low reflection and higher color type. […]
