Transparent tv is a future of tv screen you many times see the transparent screen In science friction movies like an iron man and almost all Marvel movies.
But is this exists in the real-world so hear is the future.
LG is the first company
who represents a transparent tv this is possible due to the OLED
technology the difference between the
OLED and LCD displays are there are multiple layers required to show the image
but in OLED there is only one single later which carries an 8milion pixels on it.
In OLED each pixel produce light itself they don’t need any
external light sorce to make a picture
so that we can use the OLED technology to build a transparent screen.
In the LED display there are many layers required and the main layer
is backlight panel so we cant see true the screen but in OLED there is only
one layer but the material used in that has very less LTE mean light transmission
efficiency.
Light transmission efficiency is the property of a material to allows
light to pass true the material if the light transmission efficiency of
material is 100% then it’s turned into invisible but it is an ideal condition
there is no material on earth which has 100% transmission efficiency even glass
has 94%.
If we use the material which has a very high light transmission
efficiency then we can see true the screen this how transparent screen work.
The company’s like a
Samsung and LG thy make a working model of the transparent screen but this
screens are not 100% transparent.
The working models of the transparent screen are only 70% to75%
transparent and it does not work good in
darkness or when light availability is less at that time this screen does not
work good and its manufacturing cost is very high so we can’t make it at global
scale.

The Samsung tack a working model of transparent display tv in
2019 but it doesn’t for a home application it’s only for research this tv is not
available in the market.
But for a transparent screen lover, Samsung bulled a tv which
looks almost transparent on your home wall this is a QLED tv with 4k UHD the technology used in tv is a
AMBIENT MODE.
In this tv first, you need to tack a picture of the wall on which
you want to hang a tv it mean you need to tack a picture of tv background this
tv size is 88inch.
Then apply this picture as a wallpaper of that tv than this
tv will automatically adjust and after
this process tv looks grate it looks like tv is transparent its price is approx
19,999USD In India its approx1.50crore.

The LG transparent QOLED this is 55 inches full HD screen this screen will provide 70%
transparency its looks amazing.
This LG screen is
amazing but this screen need a backlight source this screen needs a light source so produce a good quality image so that this screen can not work good in darkness.
It's not applicable for home entertainment if you use it at
home than if you are watching a movie then due to the transparent screen due to
wall in the back or due to the background of tv screen quality and image on screen looks very bed and at some
time screen doesn’t work.
So due to these problems LG
could not release this tv for sell and they don’t give any specification
or any price for this tv.

some additional technology Panasonic
will overcome the problem of the requirement of light.

led pleased behind the screen so you can use it in dark areas but this led make
the screen bulky.
If we made a truly transparent display than there is a list
of applications which are as below.
