FEATURES

• High contrast ratio, high aperture structure

• 1680 X 945 pixels resolution (16:9)

• Color Gamut (Typical 45%)

• Low power consumption

• Single CCFL

• DE(Data enable) only mode

• 3.3V LVDS Interface

• Onboard EEDID chip

• RoHS Compliance

APPLICATIONS

• Notebook PC

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