Sony Ericsson Xperia Play Stirs Users Sensibilities

The Sony Ericsson Xperia Play is having numerous interesting features that make it a great device to explore. Prominent among such features are a 4.2 inches capacitative touch screen of 480x854 resolution, LED-backlit LCD screen, Android 2.3 (Gingerbread) OS, a 1 GHz Qualcomm Snapdragon processor, Adreno 205 GPU 512MB RAM, microSD slot available, a 5 MP camera capable of HD recording, front facing camera also present, has a PlayStation suite for downloading PSP games.

The LED technology used on this handset is used in various fields and consists of easy to understand technology. Light-emitting diodes or LED is used in aviation lighting, automotive lighting (e.g. brake lamps, turn signals and indicators) apart from traffic signals. The compact size, narrow bandwidth, switching speed, and extreme reliability of LEDs have permitted new texts and video displays together with sensors to be developed, with high switching rates being used in advanced communications technology. Infrared LEDs are also used in the remote control units of devices such as televisions, DVD players, and other domestic appliances.

It is based on pretty straightforward technology in which electrons combine with electron holes within the device, to release energy. This effect is called electroluminescence with the colour of the light is based on the energy gap of the semiconductor. It is small in area (less than 1 mm2), and may use integrated optical components. LEDs are having many advantages over incandescent light sources which involves lower energy consumption, longer lifetime, improved robustness, smaller size, faster switching, together with greater durability and reliability. LEDs that are strong enough for room lighting are quite expensive and needing more precise current and heat management than compact fluorescent lamp sources of an equivalent output.

The development of LED technology has resulted in its efficiency and light output rising rapidly, with a doubling occurring about every 36 months since the 1960s The advances generally are due to the development of semiconductor technologies together with advances in optics and material science.

The Sony Ericsson Xperia pro represents an entirely different experience with the mobile audibly making sounds inside its plastic casing, and every single button is stiff and unresponsive. Holding it has been compared by some to being akin to holding the ancient fossil of a mobile device. The display is also placed rather low on the device with the buttons also not exactly being handy.It has three central command keys beneath the screen, dedicated buttons on the side of the phone for both camera and camcorder, volume keys, and a lock/unlock key situated behind the mobile, just above the camera. It is not easily detectable if you look at the front of the device as the control buttons are not easily viewable.

Sony Ericsson Yendo is a wholly different experience, being a touch screen walkman phone. It is having a 66mm (2.6-inch) touchscreen, with Sony Ericsson's own operating system together with a four-corner interface that enables the screen to dominate this device. It is ideal for social networking and is also having Walkman features that include an FM radio, Touch TrackID, describing the name of a sound track with a single touch, MediaGo for syncing with your PC, and PlayNow for quickly accessing music.
