NEC Electronics Announces World's First Implementation of Mobile CMADS(TM) |
NEC Electronics has announced that its uPD161833M and uPD161605M LCD driver
ICs, based on its Mobile CMADS(TM) (Current Mode Advanced Digital Signaling)
high-speed serial data transmission method, will be employed in select NEC
mobile handsets from the fall of 2005. This marks the first successful
implementation of cutting-edge display drivers with integrated receiver
circuits, as well as the first use of NEC Electronics' Mobile CMADS technology,
designed to enhance data transmission speed, performance, and mobile handset
design.
With the growth of third generation (3G) handsets with high-definition
displays and video processing functions, the volume of information transmitted
between the display and the main terminal has multiplied dramatically. Data
transmission rates for 3G handsets now typically exceed 90 megabits per second
(Mbps) for quarter video graphics array (QVGA) and 460 Mbps for video graphics
array (VGA) displays. Moreover, this data must be passed through a narrow
connection using serial wiring between the display and the main terminal, but
there are several challenges associated with conventional serial technology
such as high power consumption and electromagnetic interference (EMI) noise.
NEC Electronics' advanced Mobile CMADS solves the problems of serial
interface technology. By decreasing the number of data transmission lines
between the narrow LCD and main handset to 4 lines (as compared to 18 lines
for parallel technology), circuit board design is simplified, facilitating
creative handset designs such as swivel-type models. Mobile CMADS also
reduces EMI noise by approximately 35%, and lowers power consumption levels to
the equivalent of parallel transmission levels, while still delivering the
fast data transmission rates that are only possible with serial technology.
NEC's implementation of the uPD161833M and uPD161605M LCD driver ICs is
expected to be the first step in a wider industry adoption of the Mobile CMADS
technology and products. NEC Electronics will continue to promote Mobile
CMADS by implementing it in the company's MP211 application processor, and
advancing it among mobile handset manufacturers and other semiconductor
companies as a global industry standard.
