GENERAL DESCRIPTION

DESCRIPTION

LTN184KT01-A01 is a color active matrix TFT (Thin Film Transistor) liquid crystal display (LCD) that uses amorphous silicon TFT as switching devices. This model is composed of a TFT LCD panel, a driver circuit and a backlight unit. The resolution of a 18.4" contains 1680X945 pixels and can display up to 262,144 colors. 6 O'clock direction is the optimum viewing angle.

FEATURES

• High contrast ratio, high aperture structure

• 1680 X 945 pixels resolution (16:9)

• High Color Gamut (Typical 60%)

• Low power consumption

• Fast Response

• Single CCFL

• DE(Data enable) only mode

• 3.3V LVDS Interface

• Onboard EEDID chip

• RoHS Compliance

• Windows Vista Premium Logo compliance

APPLICATIONS

• Notebook PC

• If the usage of this product is not for PC application, but for others, please contact SEC

hard and rigid enough so that the Module would not be twisted or bent by the fixture.

(5) If product is used for extended time excessively or exposed to high temperatures for extended time,

there is a possibility of wide viewing angle film damage which could affect visual characteristics.
