Touchscreen Mobile Phones

                        A touchscreen is an electronic visual display that can detect the presence and location of a touch within the display area. The term generally refers to touching the display of the device with a finger or hand. Touchscreens can also sense other passive objects, such as a stylus. The touchscreen has two main attributes. First, it enables one to interact directly with what is displayed, rather than indirectly with a cursor controlled by a mouse or touch pad. Secondly, it lets one do so without requiring any intermediate device that would need to be held in the hand. Such displays can be attached to computers, or to networks as terminals. They also play a prominent role in the design of digital appliances such as the personal digital assistant (PDA), satellite navigation devices, mobile phones, and video games.

Most of the touch screen mobiles come with a TFT capacitive or resistive touch-screen. This model makes it very easy on the fingers as you wouldn't have to type on hard, plastic buttons. Any touch screen mobile phone would have a nice and great design. That has almost become a norm and over the years of development, many new and interesting designs and themes have emerged. The latest in the trend is the usage of flashy elements which are highly interactive. This is one of the greatest touch screen mobile features that make it all the more likeable. The user interface is mostly neat, with clearly arranged icons, clocks, calendars and other applications. Plenty of other touch screen mobile features are often talked about in every touch screen mobile phone review. A prominent one of the many touch screen mobile specifications would be the absence of a congested design. Almost every mobile phone has only a display and lacks any keypad, so the entire design is dependent on the touch screen. This is why they look clean and neat instead of filled and congested.

They are highly affordable today and make for a great personal and professional companion gadget!

--Disadvantages--

The touch screen mobile phone uses state-of-the-art technology. The manufacturers built this phone with a touch-activated screen which responds to your fingers. This convenience allows you to digitally operate your phone through the glassy interface. However, this innovative instrument poses some disadvantages.

--Scratching the Surface--

The touch-screen mobile, after months of usage, tends to get scratches more quickly. Fingernails and fingerprints on the screen are inevitable by-products. Although the touch screen comes with a stylus or pen-like instrument to select the icons, some users prefer to use fingers.

--Less Precision--

Depending on the size of the mobile phone and the screen, users may often find it a challenge to select specific icons. Finger sizes compared to the miniature icon sizes mean a high possibility that the user will touch the wrong command. To be exact, users need the stylus whose end is narrower to produce the desired effect.

--Environmental Risks--

Touch-screen mobiles are ultra-sensitive to weather. Due to the surface acoustic wave (SAW) technology, liquids can negatively affect the efficiency of the touch screen when they hit the screen and infiltrate the interior. As a result, the wiring and waves become short circuited and the touch screen mobile gets damaged, sometimes permanently.
