Autostereoscopic Display

Technology is ever evolving. A new technology comes in a particular field one day; the next day, we find it in the cold bag, substituted by a newer and better technology.

In the field of mobile displays, the above made statement stands as true as sunrise every morning. When new technologies including AMOLED, Super AMOLED and Super AMOLED Plus displays are incorporated in today’s smartphones, a unique autostereoscopic display has been introduced in a few smartphones to bestow the users with glass-free 3D effect for still images and videos.

Autostereoscopic Display is a technology that enables you to view stereoscopic (3D) images without the help of head gears or glasses designed especially for the purpose.  In simpler terms, it is 3D viewing without any additional hassles. At the present moment high end smartphones like HTC Evo 3D sports this feature as does the legendry gaming console called Nintendo 3D. 


There are two different methods to lend 3D effects for the viewers- Parallax barrier and Lenticular array.

In the parallax barrier technology, a second layer for LCD is placed above the main LCD display that acts like a light barrier, blocking certain pixel from reaching a particular eye of the user. The effect is precise only when the viewer’s face is located at a specific distance and angle from the screen. The exact position where, the parallax barrier gives best 3D viewing results is known as “sweet spot”. When the viewer moves away from the sweet spot, the wrong pixels get blocked, resulting in failure in 3D perception.

In Lenticular display, an array of lenticular lens is placed on the LCD. It is designed in such a way that different areas of screen are magnified and refracted in the direction of viewers’ eyes. This technology allows 3D perception at various viewing angles, that means, multiple “sweet spots’ are created along a horizontal viewing angle. Though HTC has not revealed the exact technology involved in the autostereoscopic display of Evo 3D, the product enables viewing 3D images and videos from multiple “sweet spots”, so it could be using lenticular array to enable stereoscopy.

The readers should note that the technology was pretty exorbitant in the past and continues to be the same at the present time. But as they say, quality never comes cheap!

Photo Sharing – You can easily share your photos on DLNA certified devices like HDTVs or even PCs. Moreover, you can store these pictures on the network attached storage drives. If you want to take print-outs of these images, simply connect the device wherein these pictures are stored to a DLNA certified printer.

Music Sharing – So, you have downloaded a new track on your DLNA certified mobile phone and want to listen to it on your music system. If your music system is also DLNA certified, you will just have to choose the track & select the option to play it on the music system.

DLNA Certified Devices Available in Market

Antivirus software includes auto-update feature to download profiles of new viruses so that it can check for the new viruses as soon as they are discovered and delete them. So, an antivirus is very essential for any device running on computer programs.

Mobile phones are just like computer. They also have processor and operating system. Mobile devices are connected to Internet and are susceptible to malicious programs such as viruses and malware threats. They can damage the applications as well as the operating system of the phone. Such programs can also enter the device through while Bluetooth and USB file transfer. Thus, installation of antivirus program is imperative.

Mobile antivirus is dedicated software programmed for detecting and deleting malicious programs such as viruses and malware from mobile devices. They are designed to run on mobile operating system and protect devices.

F-Secure, BitDefender Mobile Security v2, Kaspersky Mobile Security 8.0, Eset Mobile Antivirus, Norton Smartphone Security, and mcafee VirusScan Mobile are some popular antivirus software for protecting mobile devices.

What is Mobile Number Portability (MNP)?

Mobile Number Portability allows users to retain their mobile numbers when switching to another operator of choice.  MNP was launched In India from January 2011. However, MNP is applicable for porting between mobile operators in the same telecom circle only. Also, customers can port to another operator only if he/she has been with that operator for at least 90 days. Even, one can switch from GSM to CDMA network. So, users do not need to circulate the number after they switch from one operator to another – maintain contact consistency with one number for lifetime!

How to port number:

Type a text message PORT <Your Mobile Number> to 1900

Subscriber will receive an SMS with unique porting code. Please note, porting code has an expiry time. So, subscriber should apply to the new operator with that code within the specific time.

Submit required documents to the new operator.

New operator will provide you a new SIM card.

Once your number is ported, you will lose the network coverage from the previous operator. Insert the new SIM (which you got from new operator) in SIM slot of your phone and experience services of the new operator.

Why you need to provide porting code to new operator:

The new operator will communicate with existing operator and ask for permission using the porting code. When the request is approved from the old operator, new operator will set a time for porting and communicate this to MNP provider. On the decided date, the current operator will disconnect the number and pass the message to MNP provider. Now, the new operator will claim that number and MNP provider would maintain a central database with the new details.

You Must Know

The maximum charge for MNP is Rs.19.

Users can change operator multiple time after completion of at least 90 days with one operator.

Your number will be dead for about 2 hours when switching from old operator to new operator.

Prepaid balance cannot be carried forward to new operator.

MNP allows switching from CDMA to GSM.
