Panel makers show off AMOLED advances

PANEL MAKERS in the Far East are wandering around marking out
territory on their latest battleground.
Not content with the measly number of letters in the acronym OLED,
the Koreans and the Taiwanese are bringing out the artillery over
AMOLED.
Taiwanese firm Chi Mei EL Corporation (CMEL) reckoned its 25-inch
AMOLED TV panel was the dog's proverbials as it showed it off
proudly at the FPD International trade show in Japan. While on
further shores of the Yellow Sea, at the Korea Electronics Show,
Samsung bragged that its 17-inch AMOLED screen was only 12mm
thick.
Not only are Active matrix (AM) OLED panels crack-model thin, they
are also supposed to offer an ultra-wide viewing angle, ultra-high
contrast, and ultra-fast response times.
CMEL said it used low-temperature poly-silicon thin film transistor
(LTPS TFT) process technology from its mates at Chi Mei
Optoelectronics (CMO) together with its own organic light-emitting
diodes (OLED) to develop its 25-incher.
Samsung said its display commands a less-than-0.01ms response time
at 1,600 x 1,200 resolution with 400 nits of brightness and a
1,000:1 contrast ratio.
Samsung SDI presented 17-inch AMOLED TV set at KES 2006. The panel
is only 1.8mm thick and the TV set is just thin as 12mm. It
features a brightness of 400 candela, a contrast ratio of 1,000:1
and 170 viewing
angle.
