Samsung SDI and LG Philips LCD separately announced
new active matrix organic light emitting diode (AMOLED) displays. LG
Philips announced the development of the world's first full-color, flexible
AMOLED that uses amorphous silicon (a-Si) technology, while Samsung announced
the mass production of its new ultra-thin displays.The Samsung AMOLED display touts a 2.2-inch screen at a 320x240
resolution, 262, 000 color reproduction, a 10,000:1 contrast ratio, with a 100%
NTSC color gamut, and a life span of around 50,000 hours when set at 200cd/m2
brightness. The display also has a thickness of 0.52-mm.
While the LG
Philips display holds the same resolution as the Samsung model, this model
can reproduce 16.77 million colors. This 4-inch display stands at a
thickness of 150-nm, barely thicker than a human hair. Its durability and
protection against heat is due to a stainless metal foil substrate, improving
the manufacturing process and product stability.
“This display capitalizes on the strengths of OLED technology and its image
quality is really something to behold,” said Hyunhe Ha, executive vice
president and the head of the Small & Medium Displays Business Unit at
LG.Philips LCD. “Although we are still in the initial stages with this
technology, we expect to make some exciting advances in the near future.
LG.Philips LCD is focused on customer-centered technology development to
introduce products that customers want.”
Using the a-Si backplane technology, LG is allows to use its existing TFT-LCD
production line for the AMOLEDs, making the product commercially viable.
Samsung is starting mass production on its displays, and LG will be showing its
display at the Society
for Information Display (SID) 2007 in Long Beach, California on May 20th.
