What to look for when buying a mobile phone
(Part II)

Today we
Let's talk about the display
In the previous topic
There was a lot of technical talk about the processor
I deliberately left some incomplete so that the readers would not be burdened with difficult language
Especially the course
Most friends asked how good the processor was
Almost every mobile phone today has an Octa Core processor

Inside the processor are the cortex
There are usually two power full and six power efficient courses
Don't go too deep
Yeah Al that sounds pretty crap to me, Looks like Processor aint for me either
That is its manufacturing process
The mobile still has a processor built on seven nanometer process
It is rumored that Apple's A14 chip will be manufactured on a five nanometer process
Seven-nanometer processors are also available in flagship phones
The only Huawei Nova 7i in the budget range is the phone that comes with a budget of seven nanometer processor.
Otherwise, Xiaomi and RealMe are also offering eight nanometer processors in this range
Well, leaving the discussion of processors, we talk about displays
Display:
There are many types of displays
After the type, the resolution, then the pixel density and nowadays the refresh rate has also become an important thing in the display.
You in categories
Super emulated
Emold
IPS
اولید
Retina
TFT
Displays are visible
There are many more types but only two displays IPS and AMOLED are used more in mobile phones nowadays.
This question is usually asked
Which display is better?
Like the processor, there is no single answer
Each display has its advantages and disadvantages
Super emulated and emulated:
Basically both are OLED panels
But Samsung calls its OLED panel the Super AMOLED panel
According to Samsung, Super AMOLED is better than the difference of nineteen from Old
I am not going to tell you in this post what is the abbreviation of Super Emmold or what is the abbreviation of Oleid.
How many transistors are in it?
Or what is their working principal?
These things you can search on Google
The AMOLED or Super AMOLED display is generally considered to be the best because of its good colors and low battery consumption.
But for long-term use, Super AMOLED has problems with screen burn
There is also a problem with the use of direct sunlight
The AMOLED display is very thin, which helps keep the phone small
When the touch panel has been integrated in Samsung's Super AMOLED display
In that sense, Samsung's display is thinner but more expensive
LCD:
LCD (including IPS Retina etc.) panels are much cheaper than Super AMOLED
They are fat and consume more batteries
And also look good in sunlight
Because of their cheapness, these LCD panels are often used in the budget range
Apple names its IPS panel Retina Display to differentiate itself from other companies
A new technology with IPS
There is also LTPS which is 19 basis better than IPS
Better a poor horse than no horse at all
TFT:
This is the worst quality of the screen
Quality is not special with very low color range
Usually companies, Samsung etc. use it in very budget range phones
Like now Samsung's A21 has the same display panel
I would not advise you to buy a mobile phone with this display
Yeah Al that sounds pretty crap to me, Looks like BT aint for me either
So the answer is confusing
Super AMOLED where good color and battery saving
In direct sunlight, the viewing angles do not improve and the issue of screen burn also arises.
They are also very expensive
If the Super AMOLED display of a 34,000 phone breaks, it could cost you 7,000 to 10,000.
When IPS will be available in three to five thousand
The advantage of IPS is that its phones are cheaper
Can be used for a very long time
And if they break, they become cheaper
The disadvantage is the high battery consumption
And the colors don't look as good as they do on the AMOLED display
If I had to choose between the two, I would prefer Super Emold
But if a mobile is cheap and the performance is good, then there is no objection to the IPS panel
Brightons
The other thing we have to look at with the display is its brightness
In other words, if your display is bright enough that you can easily use your mobile in sunlight in a hot country like Pakistan, you will see the display clearly.
So the nut formula is used to measure brightness
Now good phones in the budget range
They have a brightness of 400 to 600 nuts
While expensive phones like flagship phones go from eight hundred to twelve hundred
And the mid-range lasts up to five hundred and six hundred
Try to have a phone with at least nuts should be above four hundred nits!
Along with the most important thing to look at in terms of your display
That is his
Resolution:
I think Budget Mobile should come with a full HD display
However, entry level phones are only coming in HD resolution right now
Samsung is sometimes offering budget range phones only in HD quality
Ok
Phone display resolution
HD 720 pixels
Full HD one thousand eighty pixels
Quad HD 1440 pixels
Four hundred and sixty pixels
Consists of
The quality of Four came in one or two phones
Especially in Sony Xperia 4K
While Quad HD is available in almost every flagship phone
While some in the budget and mid-range
The premium mid-range also has a full HD display
In Pakistan, at a price of less than Rs 25,000, almost every phone is being given 720 HD resolution.
Depending on the display resolution, you can watch Quad HD quality on the phone from HD Full HD on YouTube or Netflix.
Whenever you try to call, the resolution should be one thousand eighty pixels, ie prefer a phone with full HD resolution.
HDR:
Some premium mid-range phones, while most flagship phones also support HDR
HDR is called the High Dynamic Range
Simply put, the video quality on your screen improves
And some videos are only recorded in HDR
So you can see that on the screen too
The Pub G game also comes with the HDR option
People whose displays are HDR certified and whose GPU processors support HDR graphics can truly enjoy HDR graphics.
Pixel density:
Another thing in the display is the pixel density
Some screen quality is very low
Due to which we also see the result of a display with good resolution cracked
A pixel density above 400 is best
Anyway, it doesn't matter more than two and a half hundred pixel density
The PPI method is used to measure pixel density
Inch on pixels
It has a direct bearing on your display resolution
Normally, an HD display of 720 pixels has a density of less than 300 pixels
Refresh rate:
Sixty Hz refresh rate has been running in smartphones for almost ten years.
For the first time in OnePlus Seven Pro, OnePlus gave a refresh rate of 90 Hz, then Google gave a refresh rate of 90 Hz in Pixel Four devices.
And then the trend of higher refresh rate started
The Samsung S Base series now has a refresh rate of 120 Hz
While one of the ROG gaming phones has a refresh rate of 144 Hz.
The iPhone, on the other hand, is quietly using a 60 Hz display
And the good news is that the iPhone 12 series will have a refresh rate of 60 Hz
Because Samsung has refused to give Apple its 120 Hz display
Now you may be wondering what the refresh rate is
This is what is meant by refresh rate
How many times your screen pixels are refreshed per second
This makes your screen look very smooth and smooth
The higher the refresh rate, the better and smoother the display will look
The game also has forty frames in the budget range
But flagship phones with 90 Hz or more can enjoy high-frame games.
Fortnight, for example, can be played at 90 frames per second, provided you have a higher refresh rate display so you know the difference between frames.
All high refresh rate displays are expensive and carry extra load on the battery.
In the budget range in Pakistan
The Real Me Six and the Real Me Six Pro are the only phones offering a 90 Hz display at 40,000 to 50,000.
On top of that, the Real Me X3 Super Zoom is a phone of eighty thousand
And the PokÚ©Ùˆ F2 Pro is a 110,000 phone
And the Samsung S-Base series is offering a display of 120 Hz above 1.5 million
In the next section we will talk about camera, aperture, focal length, quality etc.
