SAMSUNG Develops High-resolution LCD Mobile Display that Automatically Adjusts Brightness


Seoul, Korea - March 27, 2007: Samsung Electronics
Co., Ltd., the world’s largest provider of thin-film transistor, liquid
crystal display (TFT-LCD) panels announced today that it has developed
a 2.1” LCD panel for high-end mobile devices that will provide qVGA resolution
and comes equipped with sensors designed to adjust brightness to optimize
ambient lighting. Screen brightness is automatically adjusted to enhance
readability under any lighting condition.



Designed for use in high-end mobile phones, PDAs and portable media players,
the new panel also has a temperature compensation sensor embedded in its
LCD driver IC that maintains a steady operational mode regardless of any
temperature change in the surrounding environment.



The Samsung panel consumes 20-30 percent less electric power than other
displays with the same size and resolution.



To enable extremely slim mobile designs, the new LCD mobile display makes
use of a proprietary technology called Adaptive Brightness Control (ABC)
that is designed with an ultra-slim black matrix embedded within the display’s
structure that measures no more than a single millimeter. The ABC is part
of a unique, cost-saving architecture that consists of tiny, highly responsive
circuit sensors built into the display panel, which eliminates the need
for photo-sensors and complex signal processing circuits.



The signal processing function within the display driver IC converts ambient
light measurements from the sensors into pulse-width modulation signals.



Those PWM signals then automatically signal the LED controller in the
LCD backlight unit to adjust the screen brightness to provide optimal
readability as outside lighting conditions change.



Samsung’s LCD Business is planning to produce the new 2.1” qVGA LCD with
ABC capability in the second half of this year.
