Japan Display has unveiled a groundbreaking new paper-like display that is capable of showing full video in color. This innovative display is an ultra-thin LCD screen, and you can see it in action in the video below.
“Ordinary liquid crystal displays have a backlight, and produce the picture by using a liquid crystal shutter. But this panel doesn’t have a backlight. It reflects light from above, and the liquid crystal shutter is used to produce a monochrome image. At the same time, color filters are used, to give a color picture.”
“This display has what’s called a Light Control Layer. When the display simply reflects light as usual, it looks metallic, like a mirror. When we add this layer, the display collects light to some extent, in the direction of the user’s eyes, making it look similar to paper. But the light returns efficiently in the direction of the eyes. By developing this layer, we’ve achieved good color, which couldn’t be done with ordinary digital paper. This display can show video, so we think it’ll lead to new solutions and applications.”
Innovative Technology Behind the Display
The technology behind this new display is truly revolutionary. Traditional LCDs rely on a backlight to illuminate the screen, which can often result in higher power consumption and less flexibility in terms of design. However, Japan Display’s new screen eliminates the need for a backlight by using ambient light. This not only makes the display more energy-efficient but also allows it to be incredibly thin and lightweight.
The key component of this display is the Light Control Layer. This layer is responsible for reflecting light in a way that mimics the appearance of paper. When light hits the display, it is directed towards the user’s eyes, creating a clear and vivid image. This is a significant advancement over previous digital paper technologies, which struggled to produce high-quality color images and videos.
Potential Applications and Future Prospects
The potential applications for this new display technology are vast. One of the most exciting possibilities is its use in e-readers and tablets. Current e-readers, such as the Amazon Kindle, use e-ink technology, which is excellent for reading text but falls short when it comes to displaying color images and videos. Japan Display’s new screen could revolutionize the e-reader market by offering a full-color, video-capable alternative that still maintains the paper-like readability that users love.
Another potential application is in the realm of wearable technology. The ultra-thin and lightweight nature of this display makes it an ideal candidate for smartwatches and other wearable devices. Imagine a smartwatch with a display that looks like paper but can show full-color videos and images. This could lead to more versatile and user-friendly wearable devices.
Additionally, this technology could be used in advertising and signage. Traditional digital billboards and signs consume a lot of power and can be quite bulky. A paper-like display that uses ambient light could offer a more energy-efficient and aesthetically pleasing alternative. This could be particularly useful in outdoor settings where sunlight is abundant.
There are no details as yet on when these new paper-like LCDs will be available in our future devices. However, the potential for this technology is immense, and it could lead to significant advancements in various fields. For more information, you can find out more details over at Japan Display’s official website.
In conclusion, Japan Display’s new paper-like display represents a significant leap forward in display technology. By eliminating the need for a backlight and using a Light Control Layer to reflect ambient light, this display offers a more energy-efficient, lightweight, and versatile alternative to traditional LCDs. With potential applications ranging from e-readers to wearable technology and digital signage, the future looks bright for this innovative new display.
