Panasonic is here with an amazing "Invisible TV"
A kind of Television that turns into a transparent glass when not in use
OLED screen uses self-lighting pixels, while LED screen uses a backlight to illuminate its pixels.
HOW TRANSPARENT SCREENS WORK
OLED (organic light-emitting diode) screens produce light when electricity is applied through them.
They are used to create digital displays in devices such as TV screens, computer monitors, portable systems, handheld game consoles and smartphones.
This material does not need a backlight and filters, unlike LCD displays, which makes them more efficient, easier to make and much thinner.
It also means that they have the option to become transparent.
An OLED panel is made up of a layer of plastic sandwiched between two electrodes - the cathode and anode - all deposited on a glass substrate.
When electricity is fed through the plastic, it emits light on its own, which is why no backlight is needed.
The firm swapped out the LED screen for an OLED and now when in transparent mode, the set is completely undetectable allowing users to clearly see behind it.
Panasonic also improved the image to where it is ‘almost indistinguishable from existing televisions’
Another impressive concept design was an OLED TV with another OLED TV on the back. The 55 inch screen has a tiny bezel and 1080p imagery on both sides.Watch Video Below
