GENERAL DESCRIPTION

DESCRIPTION

LTN156AT03 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 15.6" contains
1366 x 768 pixels and can display up to 262,144 colors. 6 O'clock direction is the optimum

viewing angle.

FEATURES

• High contrast ratio

• HD (1366 x 768 pixels ) resolution

• High Color Gamut (Typical 60%)

• Low power consumption

• Fast response time

• LED Back Light with embedded LED Driver

• DE (Data enable) only mode

• 3.3V LVDS Interface

• Onboard EEDID chip

• Green product (RoHS compliance)

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.
