GENERAL DESCRIPTION
DESCRIPTION
Preliminary
LT121SS-121 is a color active matrix TFT (Thin Film Transistor) liquid crystal display (LCD) that uses amorphous silicon TFT as a switching devices. This model is composed of a TFT LCD panel, a driver circuit and a backlight system. The resolution of a 12.1 contains 800x600 pixels and can display up to 262,144 colors. 6 o'clock direction is the optimum viewing angle. FEATURES • Thin - Light weight • High contrast ratio • SVGA (800x600 pixels) resolution • Low power consumption • DE (Data enable) only mode. • 3.3V LVDS (FPD Link) Interface with 1 pixel / clock : NS DS90CF384
APPLICATIONS • Notebook PC and desktop monitors • Display terminals for AV application products • Monitors for Industrial machine • If the usage of this product is not for PC application, but for others, please contact SEC.
