• High contrast ratio, high aperture structure

• Super wide Viewing Angle

• Fast Response Time

• Wide UXGA(1920 X 1200) resolution

• Low power consumption

• DE (Data enable) only mode.

• 3.3V LVDS Interface

• On board EDID chip

• Auto Recovery Function

• Green product (Complied with RoHS requirement)

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 te mperature 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.
