Since the birth of the Android smartphone
system, smart phones get into the touch era fully and with the mainstream mode
of operation and replace the keyboard with the touch operation. As a set of
operations, cell phone screen becomes more and more important, coupled with
consumer demand for multimedia features to improve the phone's screen began to
get bigger. Now 3.7 inches, 4.0 inches has been regarded as "small
screen", while 4.3 inches, 4.5 inches is not uncommon, HTC, Samsung's
annual high-end products is 4.7 inches, 4.8 inches this year, and such an increase in digital
electronic market, next year seems to be widely spread to 5.0 inches,
but so what?
When the screen size increases to more than
4.5 inches, one-hand operation becomes more difficult, and is reflected in the
Android system "drop-down notification bar", most people need to
change the palm of your hand posture before we can put your thumb on the top of
the screen ; In addition, as the body width also increases the thumb met the
left-most screen (to the right hand, for example) also need to change the palm
of your hand posture. But this time not only to operate the comfort will be
greatly decreased, and the palm of your hand can not firmly hold the phone
(almost phone in the palm of your hand, instead of being hold), if someone does
not hit you, I am afraid of your love machine will be carried out "one
meter freefall body damage is small, the screen cracking is a major event.
Resolution is also improved with the
increase of the screen from the first 240x320, 360x480, 480x800, 540x960 up to
1280x720, but when nearing limits of screen size, resolution is still a big
upgrade, can do 1440x900 or even are likely to 1920x1080, when the
sophistication of the phone's screen will usher in a new level.
Pixels arranged on deep-seated some of AMOLED family Super AMOLED using
a Pentile of pixel arrangement, compared to the traditional red, green, and
blue sub-pixels, Pentile only red, green, blue and green sub-pixel to
"borrow" the way to achieve the three primary colors, do so can
reduce power consumption, this is very important for the widespread power
shortages screen phone, but because this technology is not mature, the pixel
grainy than the traditional pixel arrangement a manner that, so the later Super
AMOLED PLUS to abandon Pentile pixel arrangement, but the technical
difficulties to believe in the future will be resolved.
Touch screen, as its name suggests, which
need the finger touch to operate, the development of early touch screen or
resistance type touch phone only supports single-touch. With the advent of the
capacitive touch screen, multi-touch was able to the development and
popularization of now several hundred dollars Android smart phone also has
multi-touch operation. This operation will change in the future.
Such as the new Samsung
I9300, it has a variety of gestures: the
palm of your hand from right to left slide to the screenshot function, rocking
back and forth two fingers to hold down the screen zoom, single finger to hold
down the screen from side to side page switching. There are equipped with the
Apple iPhone iOS 5 Intelligent Systems 4S: four fingers to hold down the
condensation can be achieved back to the desktop features four fingers to hold
down the left and right slide program switch, four fingers to hold down the
upward sliding adjustable multi-task management.
Walking down the street, sitting on the
subway, looking ahead, it seems that noone use the traditional keyboard phone,
and even some older people also began to use large touch-screen phone, and now
a few tens dollars can buy a nice touch smart phones, the popularity of the
touch operation has already reached a very thorough stage. Large screen seems
to have become a high-end flagship synonymous with those digital
gadgets products, but the phone's large screen already reached its
limit, although the screen size may not give us a surprise, but action played
by the screen is still worthy of us to expect .
