“A liquid crystal display (LCD) is a thin, flat display device made up of any
number of color or monochrome pixels arrayed in front of a light source or
reflector. It is prized by engineers because it uses very small amounts of electric
power, and is therefore suitable for use in battery-powered electronic devices.”
An active matrix liquid crystal display (AMLCD) is a type of flat panel display,
currently the overwhelming choice of notebook computer manufacturers, due to
light weight, very good image quality, wide color gamut, and response time.

“The most common example of an active matrix display contains, besides the
polarising sheets and cells of liquid crystal, a matrix of thin-film transistors
(TFTs). These devices store the electrical state of each pixel on the display while
all the other pixels are being updated. This method provides a much brighter,
sharper display than a passive matrix of the same size. An important
specification for these displays is their viewing-angle.”

The Road to Convergence: In the Digital Era, TVs Act More Like Computers

Set Back
“Until recently, monitor technology presented an obstacle to the convergence of
televisions and personal computers. Several attempts were made to combine
computing functions with TV, but all failed because text was unreadable on
standard tube TVs”(1).

“As inherently digital devices, LCDs do not require picture tubes or digital to
analog converters to show digital TV programming. Consequently, they can be
made very thin and light. LCDs can easily be hung on walls or placed on a
small stand on top of a table, desk, dresser, or cabinet. LCD panels require less
power to operate than other TV technologies, so they can be used for seat-back
entertainment in cars and airplanes. No other technology can claim that

LCD Monitors
It’s Happening Now
“AMLCD displays are the changing the face of consumer electronics and
computer display products right before our very eyes.”

Technology of Choice
“Success is breeding success with manufacturing capacity increasing, prices
decreasing, and adoption for good reason continues to explode. AMLCD is the
technology of choice for an ever growing range of display applications.”

“One of the great advantages of AMLCD technology is its scalability…Displays
are readily available in sizes as small as 2cm, even in high resolution…And,
manufacturers have developed the skills to scale this technology up to
dimensions approaching 1 meter. No other mature technology covers this
spectrum of form factors as well.”

Thin & Portable
“An additional benefit of AMLCD is the other dimension: its thin. This enables the
integration of a high resolution, high quality, display into virtually any application
so long as the XY display space is available. Depth has been reduced to almost
a non issue. And along with a trim format comes low weight, a significant
consideration in portable applications.”

AMLCD Applications
-Laptop Computer Display
-Computer Monitor Replacement
-Flat Panel TV/HDTV
-Small Format Portable Appliances
In the last year hundreds of consumer electronic products have emerged with
small format, high quality, AMLCD displays. These include color PDAs, digital still
cameras, new 3G cell phones, video phones, portable TVs, portable DVD
players, etc. All of these products leverage the small thin format, light weight, and
low power advantages of AMLCDs to enable products that have never existed
before. The day of Dick Tracey’s 2-way writst TV is upon us!

Digital Video Convergence
“AMLCD is an enabling technology. It gives designers the flexibility to use digital
video images to make products easier to use, deliver video content, and
communicate in ways that have never existed before. As such it is a digital
convergence technology, finding itself deployed in an ever increasing range of
products and applications.”
The Convergence of Monitors and Televisions
Tuesday, 08 November 2005

LCD Technology Trend
“Though some people have resisted the move to LCD computer monitors it is
becoming increasing clear that within a few year's time, they will be practically be
the only option available. The cathode ray tube has really begun to show its age
and is now barely a factor in consumer purchasing. In the ever increasing
performance and dropping prices of LCD monitors have caused this rapid, but
certainly not premature, shift”(1).

“With the increasing options and quality of connectivity the stage is set for the
convergence of the LCD monitor and television”(2).

Convergence |b| TVs & Monitors
The growing similarities of televisions and monitors has much to the with the use
of computers as media equipment and also the pressure to move to digital
interfaces. Both of these factors are only going to increase in the upcoming
years, but the convergence of monitors and televisions will probably never be

Increasing Adoption of Unconventional, Innovative Offerings
Phone Service Through Cable Companies and 'Pure-Play' VoIP Providers Is
Beginning to Make Inroads; the Number of Wireless-Only Households
Continues to Grow

“As for consumers who have not only abandoned traditional land-line phone
service, but all land-line service completely, the study found that 12 percent of
cell phone households today are wireless-only, up from seven percent in 2004
and five percent in 2003. This trend is further intensified in the 18-29 age group,
where over one-third of all cell phone households are wireless-only, according to
the study.”

“Consumers are also beginning to show shifts in the way they experience
entertainment content, including videos, television, photos and music.
Underscoring the increasing popularity of portability and convergence of
electronics for entertainment, the study shows that just over 30 percent of
households are viewing video content on their PCs, 29 percent are watching
video with a portable video player, and 13 percent of households are viewing
video content on their cell phone.”

 Swiss army knife

I read your article and really like what that have been described there. Although I
think that PDA will end up as a digital swiss army knife... that is it will be able to
do all the things ... but a dedicated device will do it better. a lot better. Inteface
wise that is.
No one in is right mind would like to navigate while driving a car with its
cellphone/pda while a dedicated device with 10" monitor could be used instead.
Nintendo DS will be a better *gaming* device as those need to be broad
(remeber the n-gage I say). and so on...

Editorial: the Killer Gadget? Convergence Is the Key

Five years ago analysts were predicting that cellphones and PDAs will eventually
merge. Many laughed at these predictions (especially PalmOS users of that time)
but today we know that the future of PDAs already lies with smartphones.
"Convergence" seems to be the key element of all new cellphones, even the
ones that are not in the "smartphone" category: they all playback mp3 for
example. It's obvious that convergence will move even further: music & video
players and recorders will eventually give in much of their marketshare in favor of
a one-device-does-it-all type of informational, entertainment & communication
product. And Apple is definitely aware of this trend.

convergence, but sheer elegance!

Though its most prominent design element is its dual-screen display, the most
compelling gameplay feature of the new Nintendo DS handheld, which hit stores
earlier this week, is its touch-screen control. And although not all of the software

the feature that makes the Nintendo DS a unique and fun gadget.,1452,63663,00.html

Future LCD use
 SEATTLE -- A television sewn into your shirtsleeve. A dashboard screen to
monitor the kids in the backseat. A 3-D computer monitor sharp enough to make
a hardcore gamer's heart stop -- or help a surgeon start one.

Another big focus: making the cutting-edge technology very low cost. While some
tech enthusiasts are willing to shell out thousands of dollars for the next new
thing, whether and how soon more mainstream versions of these gadgets will
appear in your living rooms -- or even clothing -- will depend largely on the price.

Korea's Samsung is working at what might appear to be cross-purposes. Its
massive 80-inch plasma screen is designed to provide high resolution at a low
cost, while its tiny 1.8-inch LCD screen aims to wow users with little regard to

History of LCD
John West, director of the Liquid Crystal Institute at Kent State University, has
been working on LCD technology since 1984. He says the market for flat screen
LCDs grew rapidly during the '90s with the huge success of laptop computers.
"Even with this rapid growth, it has been slower than predicted at matching the
market share of the traditional CRT," he said.

History of the Handheld

For some it was Game Boy Advance, for others it was the original Game Boy.
And for those old enough to remember “Just Say No,” Rubik cubes and Cabbage
Patch dolls – it was probably the Game & Watch. But, whichever handheld was
the first to de-virginize you from the standard, fixed console…it was most likely
from Nintendo.

Nintendo’s “games on the go” have been around for over 20 years. Some you
might remember, so you might not. So, let’s take a look to refresh your memory.
