4.3 Panel Specification  
4.3.1 General Features 
HannStar Display model HSD190MEN4-A* is a color active matrix thin film transistor (TFT) liquid crystal display 
(LCD) that uses amorphous silicon TFT as a switching device. This model is composed of a TFT LCD panel, the 
voltage reference, common voltage, DC-DC converter, column, and row driver circuit. This TFT LCD has a 19-inch 
diagonally measured active display area with SXGA resolution (1024 vertical by 1280 horizontal pixel array).
