The newly announced stretchable display was unveiled at the LG Science Park in Seoul, South Korea. The prototype shown at the event was a 12-inch display with a resolution of 100 pixels per inch and full RGB color, and could be stretched to 18 inches by pulling it.
The maximum elongation rate in 2022 was about 20%, but the stretchable display announced this time has an improved maximum elongation rate of about 50%. According to LG Display, the display is based on a 'special silicone material substrate used in contact lenses,' and by improving its properties, it has improved its elasticity and flexibility.
LG Display also claims that by adopting micro LED light sources up to 40 micrometers in size, the display is more durable and can be stretched and retracted more than 10,000 times. It also claims that the display can maintain clear image quality even in harsh environments, such as exposure to low and high temperatures and external impacts.
Stretchable displays are expected to have a variety of uses, including displays for foldable smartphones, displays mounted on clothing, and touch displays that fit into extruded car panels.
In fact, a demonstration was given at the venue of the concept of sewing a new stretchable display onto a firefighter's uniform, allowing real-time information to be shared among the team.
'We will continue to work closely with Korean industry, academia and research communities to build a sustainable display ecosystem for the future,' said Yoon Soo-young, chief technology officer at LG Display.
