TOKYO, SANTA CLARA, Calif. U.S.A, May 19, 2008-NEC LCD
Technologies,together with its sales and marketing channel in the
Americas, NEC Electronics America, Inc., today announced the successful
development of a manufacturing technology that enables more flexible
design of thin-
film transistor (TFT) liquid crystal display (LCD) panels.
The prototype design, a "heart-shaped," low-temperature poly-silicon
(LTPS) color TFT LCD module formed using two half-circular arcs and two
straight lines, has a display width of 4.0 centimeters (cm), height of
3.6 cm
and pixel pitch of 174 micrometers (146 pixels per inch). A
presentation about the new technology, titled "A Non-Rectangular Heart
-Shaped SOG-LCD," will be given at the Society for Information Display
(SID) Symposium on Friday, May 23, 2008, from 9:00 a.m. to 10:20 a.m.
in Petree Hall at the Los Angeles Convention Center. The module also
will be on display in the NEC Electronics America booth (#235) at the
SID ExhibitionMay 20 through 22.
NEC LCD Technologies' new technology enables optimal arrangement of
gate and data lines in the pixel array and minimizes the overlaps
between
gate and data driver circuitry (*1), when the module is non-rectangular
in shape. By applying its proprietary value-integrated
TFT (VIT) technology and integrating the driver circuits into the
module along the perimeter of the LCD glass, NEC LCD Technologies has
simplified the interconnection scheme and substantially reduced the
area needed to contain the wiring and interconnections between
external circuits, thereby yielding a bezel as slim as 2.0 millimeters
(mm) (*2).
Traditional display modules are rectangular in shape, since it is
thesimplest, most efficient and versatile shape for accommodating the
pixel arrays. Recently LCD suppliers have started to introduce fairly
simple non-rectangular LCD shapes, including circles, ellipses and
rectangles with trimmed corners.The shapes have been fairly simple
because the more complex the shape, the more difficult it is to
accommodate the wiring patterns, resulting in thicker bezels and
greater consumption of power. Displays with non-rectangular shapes are
generally targeted to replace mechanical instrument gauges-such as
the speedometers and tachometers found in cars-and other applications
that require simple shapes.
NEC LCD Technologies' new technology enables LCD modules to bedesigned
with varied, more flexible shapes that can be adapted to
embedded applications and also to nontraditional LCD applications. NEC
LCD Technologies believes this development will stimulate the
development of new and unique LCD applications.
