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 .
