LCD vs TFT vs AMOLED : Display Comparision

These days screen size of any mobile phone is benchmark to compare them. The more it will be big, more you will be impressed. But technology behind that screen in not much known for most of us. Even if the persons who know about LCD, TFT, IPS, AMOLED, SUPER AMOLED will be also confused that which one is better. 

These displays are generally having two main types. First one is LCD & second one is AMOLED. We know name LCD because it is used in the wide range of electronic products. But most of us are not aware about AMOLED. So let's discuss about it. 

LCD:

LCD, liquid crystal display is made of wondrous liquid crystals. In which these crystals are combined between two couple of glasses with the use of the light source. They produce most realistic colors, but they does not represent much wider contrast ratio if we compare them with AMOLED.

TFT & IPS are also based on same LCD technology. TFT which is Thin Film Transistor & IPS is In Plane Switching. 

TFT makes LCD much efficient by making it's wiring reduced and also reduces electrodes per pixel. TFT improves image quality of LCD display.

IPS is improved from TFT by offering much better color reproduction and more accurate viewing angles. 

LCD is used in most of Sony, HTC, iPhone., etc. 

AMOLED:

AMOLED stands for Active Matrix Organic Light Emitting Diode. 

It is old technology but gained popularity in recent days. In this technology, a thin layer is made from thin layers which is zapped by an electric current. One major advantage of this technology is, it can create much thin layers and also do not require back light. This means it can create much better black colors and reduces battery usage because the back light is not used. 

Here three major colors Red, Blue and Green are divided in sub category like RGBG color. This is called as a 'pentile display'. But this have a disadvantage also, they can represent lower resolution because of much larger and visible sub pixels. 

Now a days, Samsung is known for their Super AMOLED, HD Super EMOLED displays. But this is nothing but simple AMOLED which is used with just prefix 'super'. They are traditional EMOLED. So do not fooled by these type of names. 

These are the devices which uses AMOLED technology: HTC ONE S, Galaxy series by Samsung.

Conclusion:

Now let's come to the answer that which one is better? So my answer is both LCD and EMOLED have their own strength and weakness. So it is totally dependent on you which one is like by you personally. If you try and phone and you get good resolution, better color reproduction and good viewing angles, then definitely that display is good for you.

SEO TIPS #2 : Off Page SEO

This is my second article on SEO tips. Before I already written the first article which was based on On page SEO.  On Page SEO is based on some basic things like Title tag, Meta tags & SILO architecture. Now let me come to this Off Page SEO and start the article.

1. Back Links

Back Links are nothing but your blog's relation with other blogs and sites. It means linking of both of you by which visitors can jump to your blog from that link on other blog. Back links can be made by commenting on some other blog or website and putting our blogs link in that comment. So others can notice it and visit our blog also. This linking can be achieved in many ways, but more important thing is the quality of the link.

Quality of Back Links is having these much characteristics:

• Linking with higher Google Page Rank(PR) website: To link your blog with high PR sites you must have an account on top social networking sites like Google Plus, Facebook, Twitter with your respective blog name. By doing that post your articles on that sites so that visitors come from there and you will get very good quality of back links.

• No follow and do follow links: Whenever you link something with your post at that time maybe you have noticed that rel='nofollow' . Meaning of this code is,if you include this code then reputation of your blog will not be passed to the linked blog. This phenomena are called as 'no follow' links and these type of links are not much helpful. Bloogers use it for not flowing their reputation to other blogs.
  Generally most of the premium and reputed websites do not provide do follow options, so that you can build your reputation and fetch some visitors from those sites. But if you do some research and find out sites with do follow option then definitely you can get the good site linking and more visitors. 

• Similar kind of blogs & websites like yours: Just putting your link with a comment on other blogs is not as effective as you put them on correct blog or website. If your link contains article related to technology and gadgets, then you put it on an article of religion or mythological related. It's not going to work. By doing much activities like this and if Google notice it then they can ban your blog in their search results also. So always remember to put links on the right location.

2. Social Vote

This is very very important thing for Off Page SEO. It is also very easy to understand & implement for SEO.Always be an active member on social networking sites. Not for yourself but for your blog and building SEO. Whenever you write a new article then share that article with your Facebook, Twitter, Google Plus friends and groups. This is best and easiest way to drive  a tremendous amount of traffic to your blog. Become an active member of pages, groups and communities with similar niche and share your posts and ideas with others. Trust me, this will demand patience but give you a very good and genuine traffic.  

Introduce social bookmarking widgets on your blog like following you on twitter, facebook, G+, Stumbleupon, Flickr,.etc.  Put share widget on every post, so if a reader like that then he can share it with other friends also. 

Use and be a member of bookmarking site which will save your time to bookmark your blog on every social networking site.

Samsung Galaxy Gear Vs Sony Smart Watch 2

IFA 2013 which held in Berlin, Germany bring some exciting new electronic gadgets in our world. Most of the people are talking about new smart phones like Galaxy Note 3, Xperia Z1, Iphone 5S & iPhone 5C. But one another news was not much noticed that both Samsung & Sony launched wrist watch which is really exciting gadgets called Galaxy Gear & Smart Watch 2 respectively.

Design

First of all if you look at the basic dimensions and size, you will notice that Galaxy Gear is more rectangular, and Smart Watch 2 is square shaped gadget. Gear is weighted 74 gram and Smart Watch 2 is having 123 gram with a metal strip. Both gadgets are made from metals. Smart Watch 2 having an aluminium body whereas Gear have a stainless steel body.

Display & Processor

Both gadgets come with a 1.6 inch display. Gear having a 1.63'' inch  Super EMOLED display with a resolution of 320 x 320 pixels and 278 ppi density. Smart Watch 2 having 1.6 inch Transreflective display with 220 x 176 pixels and 176 ppi density. This means that Gear has much sharper and bright display very close to latest smartphones. 

I believe that processing power is not much important in these type of wrist watches. But if you are really looking for high power then Gear have 800 MHz Samsung Exynos processor while Smart Watch 2 have ARM cortex M3 processor with 200 MHz.

Battery Life

This is the department in which Smart Watch 2 over shadows its rival by a huge margin & for wrist watches this is the key factor. Gear having 25 hour plus batter life which is really bad for a gadget like this. Wheres Smart Watch 2 having 3-4 days of batter life as per company said. Thanks to its just 200 Mhz processor and display which improves its battery performance. So if batter life matters for you then you definitely have to go for Smart Watch 2.

Other Aspects

Gear having a facility to answer your phone call. Which is not available in Smart Watch 2. But one horror fact is that it is just compatible with Galaxy Note 3, which is not released in all the markets yet. On other side Smart Watch 2 is compatible with all Android powered smart phones and provide notification related your phone. Both gadgets are not compatible with any of the iPhone.

Gear have a 1.9 MP camera which is fitted on its wrist band whereas Smart Watch does not feature any camera. 

Smart Watch 2 is NFC facilitate & Gear does not have this facility. 

Price & Release Date

Both gadgets are plan to release in closing of September this year. 

Gear will be available at $299 in USA market & INR 21,000 in Indian market.

Smart Watch 2 will be available at INR 14,000 in Indian market & I am not sure about USA market but it will be available at around $220 as per my views. 

iPhone 5S & iPhone 5C : First Look

Its almost after one year when Apple released iPhone5 last year. There was too much curiosity in the market related to upcoming iPhone. The rumor was also there that Apple will launch two iPhone. Now its exactly same and all prediction become right. So, I will not get too much time and start our review. First of all we will talk about iPhone 5S. Because it is their flagship phone and having latest hardware. 

iPhone 5S

New iPhone 5S is the successor of iPhone 5. It has first ever in the world 64 bit processor. No other phone have 64 bit processor till date. 

• A7 Chip: It is 64 bit chip which is Apple's proprietary processor made specially for iPhone. This chip gives double performance then the previous A6 chip in CPU and GPU related tasks. There is another best combination with iOS7, because they specially made it for 64 bit chip.

• M7 co-processor: This new combination included in this iPhone 5S is like a master-slave combination. Because M7 co-processor works for some miscellaneous tasks like compass, accelerometer, gyroscope tasks. So all this will be done in M7 co-processor and it will directly reduce the burden from the A7 chip. Another huge pro is that, it will increase battery life.

• Camera:  There is no doubt that iPhone will have a great camera. Yes, again its much better improved then previous one. The iSight camera comes with 8 MP auto focus camera. It is basically a five element lens which have hybrid IR filter. The camera provides features like auto focus, tap focus, face detection, burst mode, panorama.,etc. 

• Display: This phone have 4 inch retina display having 1136 x 640 pixels resolution. It provides density of 336 ppi. One huge feature added in this display is this iPhone 5S can support 'finger print' scanning! So you can lock-unlock and even use finger print as password for phone and app store. 

After discussing these key features I must say that they did not invent or bring any hurricane in specification of this new phone. But as per company's brand value, iPhone 5S will also bring big success for Apple. iPhone 5S come with grey, gold and silver of bezel aluminium case. 

iPhone 5C

People were talking about that this time apple is going to unveil another 'cheap' iPhone for some economical users. So that's here. Again with this phone I am not that much impressed. Because the main aim of this phone was to gain good market share in Asian countries like China,India. So they have to keep the price of this phone as low as possible. But that does not practically happening. 

The configuration of this phone is same as one year before iPhone5. To reduce its price they put a poly carbonate cover like Samsung for this iPhone 5C. This phone comes in colors like green, yellow, blue, pink and white color. So this is its biggest plus point. Otherwise same hardware like iPhone5. So I do not want to discuss about it more. Just enjoy its colorful back cover pictures. One thing i noted in this phone is they made its edged with much sharp curve. So it looks really cool. 

Sony Xperia Z1

Last year when Sony released their flagship phone Xperia Z, it created a new path which have the waterproof feature and stunning looks. After almost one year there were rumors related to the new phone's name in the market. The phone would be named 'Honami' , 'i10' and 'Z1'. Now Sony has officially reveled the phone with name Xperia Z1 in IFA Berlin 2013.

Previously I had written an article with leaked pictures of this phone. The phone looks exactly same. I am writing the key features in points so every one can easily understand them.

• A groundbreaking camera with Sony's award winning G-lens. It is 20.7 MP camera with EXMOR RS sensor,CMOS image sensor and BIONZ mobile technology.
• Reinvented camera application which is very well synchronized with social networks. So you can share pictures and videos live.
• The technology which is used in Sony's BRAVIA televisions. It is used here called as TRILUMINUS display.
• Like other Xperia devices this phone is also dust and water resistant.

after all these heavy features we are comparing this phone on different basis.

Camera:

There is no doubt that this phone is world's best camera phone, and it even beats Nokia's 41MP phone. As I said before that in this phone Sony has included their technology used in digital cameras. So in one word I can say about camera performance is just 'awesome'.

Screen:

This phone comes with a 5.00 inch display which is same as previous Xperia Z. The new thing is that they had included new BRAVIA technology. 

Looks:

According to me, this phone is best looking phone even surpassing the Xperia Z. There are minimal physical buttons and the buildup is thin and elegant. Thanks to aluminium bazel which gives this phone a super premium finish.

Final verdict:

The exclusive Xperia Z1 in undoubtably one of the most advance and best phone. Even if you compare it with Samsung Galaxy S4, HTC One and Lumia 1020. If Sony manages to sell it with some good marketing and price point then it have potential to get a grand success.

 

Specifications:

Display:               5.00 inch

Processor:           2.2 Ghz Quad Core

RAM:                   2 GB,upto 64 GB expandable

Internal storage:   16 GB

Resolution:          1920 x 1080 pixels

OS:                          Android 4.2

Android KitKat : Next 'chocolaty' OS

There were too much speculations related with the name of upcoming android OS. Most of the people do not know, but these names are given in ABCD order of eating desserts.
Now Google has confirmed that their next android OS 4.4 will be called as KitKat.

Yes,you may be amazed that its an official name of Nestle's product which is world wide popular chocolate. But even Nestle is happy with all these things and they do not have any problem with using this name and even their official logo of KitKat. 

I just visited the official site of Android KitKat, and it was totally outstanding. They made it very very 'chocolatey' and I think the next Android is going to bring something very very surprising to us. Before this announcement, me and some other bloggers were talking about the next OS will be called 'key lime pie'. But from suggestions Google realized that it is not very popular product, and they must change the name.

In this conference about this announcement they also said that the next step will be promoting the Nexus 7 in US and UK regions. Even they also said that they are planning to do such promotions in Asia and Latin region. One exciting news is that, some lucky winners will get KitKat bar as a gift from Google.

After the first release of android OS in 2009,which was actually called 'cup cake' ,they are continuing their policy and now even bigger OS is coming. So be ready and till the release, take a taste of this KitKat.
