Display | types of display

Types of Display:-

Today we gonna talk about the displays of smartphones. There are many types of displays to offer in a smartphone which creates a lot of confusion in consumers . That’s why it become important to know which display is good because when you go to buy a smartphone then the shop vendor or manufacturer may tell you that this particular phone comes with an AMOLED or OLED or IPS or TFT etc. in that particular situation you must know what is the difference between them. Many of you may know which display is or bad but I will tell you why that one is good or  why that one is bad. I will provide you a better approach in selecting a display for your smartphone. So, please read it up to down .

following are the types of display:-

1. L.C.D (Liquid Crystal Display)

LCD is a basic display . This Display is used in calculators and in old featured phones( phones with physical buttons ) black and white phones . This display was made-up by holding the six layer of some material . In this display we are not able see clearly under the sunlight and became its limitation .

  2. TFT (Thin Film Transistor) display:-

When LCDs became famous but due to unable see under the sunlight then to overcome this limitation LCDs under gone lot of research  then finally scientists comes with a different displays TFTs(Thin Film Transistor) as the Name suggests this displays contains a transistor which work like active – Matrix and as the TFTs contains transistor therefore they are able to generate color which makes them first colored display .

 3. IPS = In-Plane switching :-

IPS display’s was developed by L.G and Samsung but L.G. ‘s contribution is more in making IPS display. IPS displays are upgraded  version of LCD and TFT display ,TFT displays make us to see under the sunlight but its clearly upto when we look at it straight  but when we see at the mobile at different angles then the color fades and unable to see clearly that’s the limitation of TFT displays to overcome this IPS display’s were made it makes us able to see the display clearly even when tilted . IPS displays become famous very much. Now days screens of television were made of IPS display .

4. Retina Display :-

Retina display  was developed by “Apple” company . The specialty of this display is that its distance  between two pixel(the smallest unit of display)is very low . Which reduces the blurriness of image which produces excellent image quality and color contrast.

Backlight :-

Backlight are implanted under the display which is responsible for the Brightness of the display in a phone the backlight was installed in TFT displays .

5.OLED : Organic light emitting diode :

An OLED display works without a backlight : thus , it can display deep black level and can be thinner and lighter than a liquid crystal display (LCD). In low ambient light conditions (such as dark room) , an OLED screen can achieve a higher contrast ratio than an LCD .Regardless of whether the LCD uses cold cathode fluorescent lamps or an LED backlight.

6. AMOLED :- Active matrix organic light emitting diode

AMOLED is a display technology and stands for Active Matrix Organic Light emitting diodes .it is a type of OLED display and is used in smartphones . OLED display thus having clear quality it cannot produce deepest level of black which effects on battery backup . Therefore make the displays more efficient Active matrix was added in OLED display which results  in glowing the required pixel while keeping the unnecessary pixels off and also make it to generate the deepest level of black .

7. Super AMOLED display :-

Super AMOLEDs are works on the same  principal as the AMOLED’s works the only difference between them is that Super AMOLED’s display are 20% brighter than AMOLEDs and consumes 20% less battery .

 8.SLCD :- Super LCD

SLCD were developed by Sony and Samsung . SLCDs are  latest version of LCD .Its specialty is that it doesn’t have gap between the display and Outer glass due to which it looks like that videos or image were  playing on the outside of display . It gives very immersive view .

HTC used this display most in their smartphone . But it doesn’t become famous due to some reasons

9.Clear Black Display:-

Clear black display was used by Nokia in their some phones . Its specialty is that it don’t reflects sunlight which was falling on the phone under the sunlight due to which the brightness and contrast of the display remains same as in the indoor condition  able us to see in the sunlight clearly . Also its quality is very good.

Processor and core | types of core and processor company

Processor :-

Processor is a type of chip which is implanted in the mobile , computer , laptops etc.  Processors  are most important part in a mobile , computer and laptops and decides how will be the performances of that device . Processor handle’s and understands the processes between the hardware and software which will make the mobile or computer to understand what user wants to do and make the device to respond to the users command if the processor is not able to understand what a user want to do then it will give false output to a input . Processor is a communicating path way between the hardware and software . If the processor is not able or week in providing the pathway between software and hardware and it will not will gave the desired outcome . let’s see an example to understand this :-

Let assume that two people want to communicate but their native languages are different but have a second common language (like English) then they have to talk in second language to understand . processor is like the second(common) language which  help users to communicate with their devices.

Processors are  also called as the brain of computer /mobile . When we talk about a processor then we also want to know that how much cores that the processors has. Therefore let we understand about  cores .

What is core ?

In simple words cores decide the power of the processor . The ability and efficiency to do work can be decided with number of cores. If the processor comes with less number of cores like 2 or 1 then the cpu (processor) is not able to do heavy works and multi tasks simultaneously. Therefore expensive computers and smartphones comes with 4cores(Quadcore) and 8cores (Octacore) which make them able to do the task more efficiently. More the number of core more the efficiency  and more number of cores comes with more money.

Types of cores:-

1. Dual core processor : - processor with 2 cores.

2. Quad core processor: - processor with 4 cores.

3. Hexa core processor : - processor with 6 cores.

4. Octa core processor :-  processor with 8 cores.

5. Deca core processor : - processor with 10 cores.

How processor get measured their efficiency(power).

It is measured in units of gigahertz (GHz).Therefore the more number of core the larger number of GHz . Larger the numbers attached to  GHz more the efficiency processors has. Basically GHz decides how fast the hardware and software communicate with each other . therefore people purchases mobile and computer with good processor and the larger number with GHz.

Famous processor manufacturing companies :- 

There are lot of companies that manufacturers processors but the important and famous companies that produces reliable products are given below.

1. Intel

2. AMD

3. Qualcomm.

4. NVIDIA

5. IBM

6. Samsung

7. Motorola

8. Hewlett – Packard (hp)

Intel and AMD are most demanded companies in the computer industries because these companies make the most powerful and reliable processor .

what is an esim ? can you change it into another network operator ?

eSIM:-

eSIM stands for Embedded Subscriber Identification Module . The eSIM comes in some specific smartphone(for e.g. iphoneXs). This eSIM is mounted on the motherboard of your smartphone which can not be removed by the owner of that Smartphone and of course cannot be installed by owner . It get preinstalled by smartphone or smart watches manufacturer and they works on GSM technology which is also used by the normal SIMs.

esim

Which phones does comes with eSIM?

There aren’t many phones that comes with eSIM . The first phone that debuted the eSIM in the smartphones was Google’s pixel 2  followed by apple’s iphone X series(X,XS,XR) . eSIM also comes in smart watches like Samsung gears .

Some smartphones that support eSIM are :-

·        Apple iPhone  XS max.

·        Apple iPhone 11.

·        Apple iPhone 11 pro.

·        Apple iPhone 11 pro max.

·        Apple iPhone Xr.

·        Google Pixel 2, Pixel 2XL.

·        Google Pixel 3 , Google 3XL.

·        Google Pixel 3a , Google 3aXL.

·        Google Pixel 4 , Google 4XL. Etc.

(NOTE :- All the smartphone mentioned above have one SIM slot and a eSIM option).

FAST FACT :-In 2016 Samsung ‘s watch gear 2 was the first Iot( Internet of things) product that introduced eSIM.

There are more smart watches and smartphones that comes with eSIM facility and it is believed that in future eSIMs facility will be available to all the smartphones.

 

What are the Benefits of eSIM ?

eSIM benefits everyone like the device user , operator , distributers , device manufacturer and so on .

·        It stores multiple cellular profile and that why it works seamlessly across the world.

·        It doesn’t requires a dedicated slot unlike normal SIM cards. Hence it is ideal for the products that have small form factor (basically small in size like a watch ).

·        There is no possibility to lose the card as it is not within the reach of the owner.

·        It is equally secure as the removable SIM cards .It also supports integrity of billing process during roaming scenarios.

·        eSIM have simple management of subscription and connection .

 
What are the drawbacks of eSIM ?

·        If your phone or the device with eSIM some how get damaged or dead then it is not easy to retrieve data  as it is in case of removable SIM .  Therefore , users has to rely on cloud storage to retrieve the data such as messages, contacts and other important things.

·        I am not sure that this is disadvantage or advantage that a person may get in problem who do not want to be tracked when they using eSIM. But if he/she have removable SIM was able to remove the SIM and get safe from tracking.

·        User who like to use different mobile can  change its normal SIM  anytime but not in case of having eSIM.

How to use eSIM ?

To use eSIM  first you go to your network operator which can help you in converting your SIM in eSIM because you have to upload you sim info in your eSIM which can be done by the network operator by the way we can also change it by ourselves but just to be safe it is good to go to a network operator which know its work well.

Which Telecommunication will provide you eSIM facility?

In India Reliance Jio and Airtel  are the two companies which provides you eSIM facility.

Can we change the Network operator in eSIM?

The answer is yes , we  can switch it into any network operator which provides eSIM facility and we can also change the number. All you have to do go to network operator and he will make some changes in your settings  and he/she will provide a QR code which you have to scan and that’s all your network company or mobile number get changed.

It is very much easier than changing the company as in the case of primitive SIM cards.

eSIM and SIM doesn’t have lot of difference beside that it eSIM are preinstalled by the manufacturer and cannot be removed.

Therefore to get all the knowledge please read this to the end

WiFi Router:-

Router is a internet working smart device which connects 2 I.P. address .we can also call it as a smart device or a intelligent device . The routers that we use in are houses is based on ip address connection technology and delivers a high speed internet . The local area network provider(companies which provides internet) provides a wire to which make the internet accessible to us directly by connecting that wire to  our computers and laptops . But an individual wants to make it accessible to its all devices that he/she have but we can't connect that single wire to  our every devices at the same time . In this situation  a wifi router is very useful  . A wifi router make that internet accessible to our every devices wirelessly and then you can enjoy the high speed and seamless internet to your every devices  :)

(A wife router is called smart or intelligent device because it comes at very low price (online) and is very easy to install and it starts working as soon as the switch on and it keep on doing its work smartly until unless kept untouched its setting ).

wifi router

Router port:-

Routers comes with  5  ports of  which 2 ports are called line in and connect the internet wire provided by the local area network provider  . Port 3^rd is called as line out due to we will be able to connect our different devices at the same time with internet.

port

Router comes with antenna which provides wireless connection to our devices .Nowdays routers also comes with 6  antennas which provides very high speed internet and a steady connections to our devices.

wifi antenna

Modem :-

Modems are constructed with two thing a modulator and a demodulator .Modems work is to convert the analog signal coming from your landline into a digital signal because our devices are unable to understand the analog signals that why router have the modem to convert the analog signals into a digital signal(understandable by our devices(smartphones , computers , T.V.))and that type of particular data that uploaded to our computers converts it into analog system from digital signal .

modem

Broadband:-

Broadband are the type of telecommunication which transmits multiple frequencies in a wide range through optical fiber cable which will make us able to made the connection with broadband . Some common broadband which provide wire to our houses are Airtel broadband, BSNL broadband , Idea broadband  etc.

broadbrand cable

USB Dongle:-

USB dongle in which you have to insert SIM and than we can use the internet by connecting dongle though USB port of our computers and laptops and now you can use the internet of your SIM in your computer or laptop.

USB dongle

WiFi Dongle:-

Wifi dongle is similar to a USB dongle in many ways but the difference is that it connect to your devices wirelessly and can be used in different devices at the same time . To access the internet like the usb dongle we have to insert SIM into the slot given in the dongle . To power(switch on ) the wifi dongle we have to connect it to a charger adaptor and then connect that charger in the plug and then switch ON the button that’s all.
