LG Display ha annunciato l'avvio della produzione in volumi del primo display al mondo di tipo e-paper, e dunque progettato per la implementazione di ebook reader, in plastica flessibile, tipicamente indicato con l'acronimo di EPD (Electronic Paper Display).
In accordo al produttore, la nuova tecnologia è destinata a rivoluzionare il mercato dell'E-Book sia per il suo design che per le sue funzionalità: caratterizzato da una diagnale di 6-inch, il nuovo display vanta una risoluzione nativa pari a 1024 x 760 pixel e può essere piegato fino a formare un angolo di 40°, come se fosse un vero e proprio foglio cartaceo.
LG Display ha reso noto che il nuovo EPD sarà fornito prima agli ODM cinesi per poi arrivare sul mercato europeo, incluso in prodotti completi, nella prima parte di aprile.

LG Display [NYSE: LPL, KRX: 034220], a leading manufacturer of thin-film transistor liquid crystal display, announced today that it has started mass production of the world's first plastic electronic paper display (EPD) for use in E-Books. The 6 XGA (1024×768), e-ink, plastic EPD is expected to revolutionize the E-Book market with its advancements in functionality and design.
"With the world's first plastic EPD, LG Display has once again proven its reputation for leadership and innovation with a product we believe will help greatly popularize the E-Book market," said Mr. Sang Duck Yeo, Head of Operations for LG Display's Mobile/OLED division. "Based on our success in mass-producing plastic EPD, we are excited as we look toward applying concepts from this experience to future developments like plastic OLED and flexible displays."
Innovations in Functionality and Design
The world's first plastic EPD from LG Display offers users a paper-like reading experience with a plastic substrate that is as slim as cell phone protection film, and a flexible design that allows bending at a range of 40 degrees from the center of the screen. Compared to glass EPD of the same size and resolution, LG Display's plastic EPD realizes a super slim thickness of 0.7mm which is 1/3 slimmer than existing glass EPD; as well as a weight of 14g which is more than 1/2 lighter.
E-Book users have long expressed a desire for more durable EPD, since around 10% of them have damaged their product screens from accidentally dropping or hitting them. When LG Display's plastic EPD was put through repeated drop tests, from 1.5m above the ground or the average height of reading when standing, no damage resulted. When put through a break/scratch test involving hitting the display with a small urethane hammer, no scratches or breakage resulted.
As EPD gets thinner, lighter, and more durable with the introduction of plastic EPD, E-Books will be able to offer certain unique benefits compared to smart devices and tablets, including reduced eye fatigue and more efficient electricity consumption in addition to lower prices.
A Manufacturing Breakthrough
LG Display developed a unique technique to utilize the high TFT process, typically employed in general LCD manufacturing and with temperatures exceeding 350 degrees, in the production of its plastic EPD. By overcoming the obstacles associated with applying the existing production process to heat susceptible plastic, LG Display achieved a breakthrough with the successful mass production of plastic EPD able to maintain strong durability in high temperatures.
The world's first mass-produced plastic EPD from LG Display will first be supplied to ODM companies in China, followed by completed products to be released in Europe at the beginning of next month.
