TDK’s ‘UEL476’ see-through screen, now in mass production, was designed specifically for use in mobile devices

japanese electronics company TDK has just begun mass production of the world’s first near-transparent, passive matrix organic electroluminescent (EL) display.

organic EL displays use organic materials that emit light in response to an electric current, offering the benefits of a wide viewing angle and high brightness with a see-through screen. the ‘UEL476’ screen being produced is a 2.4-inch QVGA (320 x 240) display designed for mobile devices, and thus constructed to obscure light transfer through the device, preventing content from being visible from the opposite side. operable in temperatures ranging  from -20 to 85 degrees celsius (-4 to 185 degrees fahrenheit), it features 40% transmittance and no colour shifting  over the course of its life.

the development opens up numerous design possibilities for mobile devices, especially in the field of augmented reality.
