How does transparent OLED display work?||Price||Uses

Transparent Display

A see-through display is a screen that allows users to see the information on the screen while still being able to see through it. In many Hollywood movies we have already seen this technology but is it real or it is just fiction? It is True as our technology is now that mature that we have Transparent Displays but we are not using them to a high extend.

History of Transparent Display

Transparent Display was practically developed and accelerated rapidly around the end of the first decade of the 21st century.

Samsung launched its first transparent LCD in 2011 and with that Planar published their report on Electroluminescent display in 2012. Many companies came together and improved the technology for Transparent display.

How does a transparent display Works?

Majorly there are Two Types of technology behind transparent displays that are LCD and LEDs. OLEDs are quite popular and newer than both the technologies and are used widely. TASSEL displays are also used as a transparent display which is a thin Electroluminescent display with a transparent electrode. So let's Know-how LCDs, LEDs, TASEL Display are made Transparent and what is their Limitation.

1) LCDs: LCD can be made transparent without applied voltage when a twisted nematic LCD is fitted with crossed polarizers. LCD has low transmission efficiency due to the use of a polarizer and appears somewhat dim in Natural Light. LED doesn’t have their light like LED they just modulate incoming Light.

Limitation:

•  They Key Limitation to transparent display efficiency is it is linear polarizing filter.

•  LCD also requires a removing diffuser layer to adopt them for use as a transparent display.

2)LED: LED has two layers of glass on both sides of addressable LEDs. OLED screens have emissive and conductive layers in which Electrical impulses travel through the conductive layer and emit light as an emissive layer.

Limitation:

•  LEDs have their light but they cannot show black.

3)Passive Transparent Display:- Passive transparent display is a cheap option developed by MIT researchers in 2019 using nanotechnology. It requires an integrated electronic module to process visual signals or to emit light. It uses an external light source to project images and videos onto a transparent screen embedded with resonance nanoparticles that selectively scatters the projected light.

4)TASSEL Displays: These displays are based on Electroluminescent display technology. TASSEL display glass consists luminescent phosphorous layer sandwiched between two transparent electrode layers. It displays its light and has transparency up to 80%.

Limitation:

•  TASSEL displays are Inorganic and can harm the environment.

• It is capable of displaying only one color.

Application of Transparent Display:

Transparent displays are used for Augmented Reality, Retail, Event Stage, and much other cool stuff. So here we will check how it works with a Transparent display.

Augmented Reality (A.R):- If you are a Tony stark Fan then give me 3000 Likes, but have you ever wondered? How tony in Iron Man’s suit get access to random people's information by scanning through the transparent screen in his eyes? That's allis AR using Artificial Intelligence which we have all used as Google Street, Google Lens, and Google Translator. This all may be possible in our upcoming decade.

2) Retail:- Many Retailers use this Transparent display to show Products and to advertise as it is way cheaper than other traditional options.

3) Event Stage:- Transparent display is used by event managers to realize creative holographic-like visual effects.

4)Refrigerator:- On a commercial refrigerator, a transparent door can function as digital signage to let the consumer see the product. The display can also show menus, recipes, health information, or ordering information.

5)Vending Machines:- A transparent LCD on the vending machine can be used by consumers to get the Product and it also facilitates the use of NFC and QR codes. This would help the owner of Vending machine and the consumers.

How much does a transparent screen cost?

Last Year Xiaomi launched Mi TV LUX their brand new transparent television in China with a price of 50k RMB (roughly Rs 5,74,983). It has a 55-inch transparent OLED panel with a 15000:1 static contrast ratio and an infinite dynamic contrast ratio, which offers a great experience. The screen has a 120 Hz refresh rate that provides a smooth experience and it also contains an AI master smart engine which is powered by a Mediatek 9650 custom Tv chipset. Television has more than 20 optimization algorithms and dedicated optimization for 5 major scenarios, the device refines graphic resolution to create vibrant images.

Currently, this Television is not available in every part of the world, but it will soon available.
