Samsung Electronics is set to show off new LCD displays for
mobile devices at an upcoming Symposium and Exhibition in San Francisco.
Among the new displays Samsung intends to showcase is a 3.5
inch LCD with embedded touch screen, and the first-ever 7 inch LCD driven by a
single chip.
The company will also use the 2006 Society for Information
Display International Symposium and Exhibition (SID) in San Francisco to unveil widescreen versions
of 24 inch, 27 inch and 30 inch monitors commercial applications and a 21.3
inch black-and-white monitor for applications such as viewing X-rays.
Likely to attract the most attention though is the 3.5inch hTSP
(hybrid Touch Screen Panel) screen. The technology reportedly avoids the need
for a separate printed circuit board (PCB) attached to the top of the LCD panel
that contains sensor circuitry for the touch panel.
What Samsung has done is to include all sensor circuitry
within the panel itself, which for the rest of us spells thinner, lighter and
possibly cheaper devices with touch screens because the touch screen circuitry is
created in the same way as the thin film transistors for the imaging part of
the device.
Also, given the interest in Origami-style ultra portable
computing devices, the 7 inch display Samsung intends to show off could get a
lot of interest. Driven by a single chip, the WVGA resolution (800x480 pixels) takes
a similar approach of building more technology into the actual display device.
In this case, the screen uses Samsung's proprietary
amorphous silicon gate technology, which allows the gate IC function to be
built directly onto the glass panel. The time controller function also is built
into the driver IC, reducing the circuitry footprint and the number of parts by
about one-third.
Again, this means mobile products that are simpler in how
they function and thinner in shape and will make it far easier for engineers to
design and develop devices such as potable media players and GPS navigation
systems.
