Different Displays 



Full Explained of the different types of displays in cell phones



hello everyone let's just agree that all of us use different kinds of gadgets in our daily life. out of these gadgets smartphones are the most popular and technologically most advanced. i believe that rather than being an user of technologies we should know the basic workings of the gadgets that we use right. i know you are very curious to know about the technologies that we use today.

And that's why you are probably i'll explain some technical terms that you should know as a smartphone users. so let's start with this place do you know what kind of display your smartphone has. you might have heard of lcd displays and led displays
but there are a lot more distinctions such as lcd amoled super amoled and so on. okay so let's start with lcd displays or liquid crystal displays.

LCD display

Lcd displays has an illuminating layer that is made to pass to liquid crystal layers that can convert light into a certain wavelength of colours. and it use some filters to ultimately get to us. smartphone uses a technology called ips lcd which provides better viewing angle and color reproduction.

IPS LCD

And the advantages of ips lcd displays are they are well known for their energy efficient properties and are also inexpensive. now let's look at amoled displays.

Amoled display

A few years ago led displays started becoming popular with high-end smartphones. nowadays they are available in mid-range smartphones too amoled displays are known for their punchy colors and deep black. amoled displays are superior because they use individual leds to create pixels that lights up to form images. 


 

Actually this is an over simplification as there is a lot more to it than just lighting up leds amoled displays looks much better than lcd displays and they consume less power. but they cost more and hence they are not available in budget phones you might have heard of super amoled well that is a marketing term samsung use in its advanced amoled displays.

Super amoled display

Super amoled is a more advanced version of amoled and in degree touch sensors and the actual screen in a single layer. super amoled is even better at this with a 20 percentage brighter screen 20 percentage lower power consumption and 80 percentage less sunlight reflection. now let's learn a parameter which helps the quality of visuals in a display called nits it is the measure of light

Emitted per unit area this unity sword is frequently used to specify the brightness of a display in devices basically this feature provides brightness keys to control the brightness of phone display. and about 600 to 700 nits are required for a proper brightness in a smartphone moving on to hdr displays hdr and smartphones stand for high dynamic range and it refers to a technology that let you see the incredible details

even in a very bright and dark area of a scene also for the efficient working of your smartphone there are some other elements called refresh rate and touch response rate. where the refresh rate is the number of times a display refreshes to show a new image and its unit is heads for an example if 144 heads is the refresh rate it means that the display refreshes 144 times per second to load a new image and normal smartphones are capped at 60 hits so if a display

has a higher refresh rate then the animations and graphics that we see in the display will appear to move smoother but the refresh rate will consume more battery power higher refresh rate was only available for high end smartphones and they have 90 hits 120 hits and even 144 hertz refresh rate displays but nowadays even mid-range smartphones come with high refresh rate displays the only difference is that while high-end phones use amoled displays with 90 or 120 heads refresh rate mid-range displays use ips lcd 90 or 120 hertz displays also there is something similar to refresh rate such as touch response rate.

Touch Response Rate




In simple words touch response rate is a frequency of a screen to register it touched by the user it means that how many number of times in a second the screen will look for touch input it is also measured in heads smartphones doesn't use chess processors they use something called system on a chip or soc which is equivalent to a computer motherboard including main

processors graphic processor and memory on a single ship in other words a system on a chip is an integrated circuit that integrates all over most components of a computer or other electronic system now lpddr or low power double data rate npdr is a type of double data rate synchronized dynamic ram that consumes less power and it is targeted for mobile computers the next one is

Ufs or universal flash storage

Universal flash storage provides standard specification for storage used by mobile phones and other consumer devices in 2018 the latest ufs 3.0 was announced it promises up to two times the bandwidth while using lower cover a single lan can carry 11.6 gps device worth ufs 2.1 standard could manage and ufs 3.0 is used in high-end smartphones the speed of a smartphone depends a lot on the storage speed of a smartphone also let's look at two more features

that act as a safety property of the smartphone first one is ip rating or endless protection rating it classifies and rate the degree of protection provided by mechanical casing and electrical enclosure against dust and water in the smartphone with this we can protect the inside of smartphone from water damage high-end smartphones have ip ratings such as ip67 ip68 etc from mid-range

smartphones are protected from water by using p2i nano coating now p2a nano coating is a hydrophobic coating that is applied on your smartphone's internal and external side this coating will not allow water to stick on the surface of your smartphone's part so that's it these are some of the technical terms that you should know about smartphones.
