OLEDs offer several key advantages over other display technologies:
- Deeper blacks and higher contrast ratios: OLED pixels can be individually turned off, resulting in true blacks and contrast ratios of up to 1,000,000:1 or more.
- Wider viewing angles: OLED displays maintain consistent color and brightness from virtually any viewing angle.
- Faster response times: OLEDs can switch pixels on and off in less than a millisecond, eliminating motion blur.
- Energy efficiency: With no need for a backlight and the ability to selectively turn off pixels, OLEDs consume less power than LCD and LED displays.
The Rise of Transparent OLEDs
Building on the success of their OLED technology, LG has been pioneering the development of transparent OLEDs. These displays take the advantages of OLED a step further by allowing light to pass through from both sides, creating a see-through effect when the display is turned off.
Transparent OLEDs are constructed using transparent or semi-transparent materials for both the electrodes and the organic light-emitting layers. When powered on, the display functions like a regular screen, displaying vibrant images and videos. When turned off, the transparent nature of the materials allows the display to seamlessly blend into its surroundings.
LG has been refining their transparent OLED technology over the past few years. In 2019, they introduced a 55-inch transparent OLED display with a transparency of 40%, meaning 40% of light could pass through the screen. By 2021, they had increased the transparency to 55% while maintaining high image quality.
