CEATEC - Rohm shows tiny OLED for camera viewfinders

Rohm is showing off a prototype OLED display designed for use in camera viewfinders.

Rohm is showing off at this week's Ceatec exhibition a prototype full-color OLED (organic light-emitting diode) screen that's smaller than a fingernail, yet offers resolution of 320 pixels by 240 pixels.

The tiny display, which measures approximately 4 millimeters (mm) by 3 mm, is embedded in a prototype chip and is designed for use in a video-camera viewfinder, said Yasufumi Ueno, a Rohm spokesman.

The full-color image on the OLED display is barely visible to the naked eye and requires a magnifying glass to be seen clearly. Under a magnifying glass, the prototype screen showed a detailed image of a woman dressed in a kimono, standing outside a traditional Japanese home surrounded by trees with colorful Autumn foliage.

Plans to commercialize the prototype display are not yet confirmed, Ueno said.

The company is also developing a tiny OLED display with a resolution of 640 pixels by 480 pixels, but did not offer a date for when it will be ready.

OLED displays are produced using carbon-based materials that emit light when an electrical field is applied. They don't require a backlight, which makes them thinner than other displays. And they offer better colors and higher contrast than LCD (liquid crystal displays) and other technologies.

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.

Brainstorming, innovation, problem solving, and negotiation have all become much more productive and valuable if people can easily collaborate in real time with minimal friction.

The print quality also does not disappoint, it’s clear, bold, doesn’t smudge and the text is perfectly sized.
