LG Display said Thursday that it started mass production of a thinner and lighter electric paper display.
The technology, termed EPD, Electronic Paper Display, utilises e-ink technology in combination with a plastic layer and, is capable of bending at an angle of up to 40 degrees from the centre of the screen. At the same time, it is up to one third thinner and half the weight (14 grams) of competing glass displays, at a thickness of 0.7mm and a weight of 14g, in a six inch form-factor. The 6" display will feature an XGA, 1,024 x 768 resolution, which works out at 213 pixels-per-inch.
LG added that the screen comfortably passed drop tests of 1.5 metres and would tackle the issue of screen damage, which the firm claims to affect 10 per cent of all e-reader users.
LG Display developed a 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 says it has achieved a breakthrough with the mass production of plastic EPD able to maintain strong durability in high temperatures.
The 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.
LG also plans to create flexible OLED displays in the near future.
