• WXGA (1280 x 800 pixels ) resolution
• Low power consumption
• Fast Response
• Single CCFL
• DE(Data enable) only mode
• 3.3V LVDS Interface
• Onboard EEDID chip
• Pb-free product
APPLICATIONS
• Notebook PC
• If the usage of this product is not for PC application, but for others, please contact SEC

Note 5) After stabilizing and leaving the panel alone at a given temperature for 30 min , the measurement
should be executed. Measurement should be executed in a stable, windless,and dark room.
30 min after lighting the backlight. This should be measured in the center of screen.
