LG to launch 55-inch transparent OLED TV at CES 2021

LG along with other devices has showcased a transparent OLED TV titled the OLED Smart Bed during the CES 2021 week. According to the company, the new transparent OLED TV can be moved around the house with much ease and the TV is a complete reimagining of the past transparent LCDs.

The LG 55-inch OLED TV is a rollable TV that can be fixed at the foot of the bed which will rise up partially or in full according to the preferences of the user. The transparent TV can also maintain the view of the other side of the TV.

The new OLED TV comes with built-in speakers and is a better version of the past transparent LCD TVs that only managed to gain 10 percent transparency, while the new one has successfully achieved 40 percent transparency. The users will be able to see through the transparent TV even if the TV is displaying an image.

Jong-sun Park, senior vice president of LG display and the head of commercial business, said, “Transparent OLED is a technology that maximizes the advantages of OLED and can be used in various places in our daily lives, from stores, shopping malls, and architectural interiors to autonomous vehicles, subway trains, and aircraft…It will grow into a next-generation display that can change the existing display paradigm”.

The company quite clearly aims to sell the product to high-end consumers and has already launched the world’s first-ever rollable TV in South Korea in October, last year. The price of the rollable TV was $87,000 (INR 63,91,615).

The transparent OLED TV is said to be designed for public utility. The commuters can enjoy the view of the city while reading the information displayed on the screen. The transparent OLED display was seen being used on the subway, giving out information about the routes along with weather and time. 

The price of this product has not been announced yet. The transparent OLED TV or the 55-inch ‘Smart Bed’ can also analyze the sleep patterns of the user and act as an alarm clock.

How does transparent OLED TV work?

OLED TV has a single panel that has 8 million pixels lighting up the screen. Each of the 8 million pixels is capable of producing its own light. A transparent OLED TV, which also has a single panel, allows the TV to appear transparent when the pixels are turned off. When the pixels in a transparent OLED display is turned on, it is not as much ‘see-through’ anymore. The blacks in the transparent OLED allow around 40 to 50 percent transparency, however, the other colors in a transparent OLED TV do not give out much transparency which means that if the colors are vibrant not much can be seen what is taking place behind the screen.

The transparent OLED displays are constituted of only transparent components such as substrate, cathode, and anode. The transparent OLED display allows light to pass through in both directions when the transparent OLED TV is turned on.
