The leading growth area for
active matrix small/medium displays was in cellphones, driven largely by the growing demand for smartphones.
However, it still looks minute compared to the 1.75 billion units of small-sized
active matrix liquid crystal display units shipped in the same time period.
Active Matrix provides parallelism with more than 18,000 I/O pins and 4,000 programmable power supplies and a shortened signal path to pin electronics that improves signal integrity.
The Dell UltraSharp 2408WFP 24-inch widescreen flat panel TFT
active matrix LCD monitor provides excellent color accuracy and uniformity from a 3000:1 contrast ratio and 400 cd/[m.sup.2] brightness.
Another factor:
active matrix TFT-LCD displays found in many mobile and handheld products.
There are two kinds of OLEDs: passive matrix, and
active matrix. Passive matrix displays are far more limited than active displays, currently viable only for displays about2 inches in diagonal; whereas
active matrix OLEDs can be used in displays up to 70 inches in diagonal.
The portable unit weighs 25 pounds and contains all required cabling, a dual-processor Windows XP Pro x64 system, a 15-inch
active matrix display, keyboard and 1.5 TB total storage.--Network Instruments
CMEL plans to incorporate Kodak's
active matrix OLED display technology in small panel, mobile displays.
