An O-paper display has the appearance of ordinary ink on paper, for it reflects light like ordinary paper. Unlike conventional LCD displays, which emit lights, the O-paper display is highly readable, not only indoors but also in direct sunlight, and the image on it is clear and modest, without flickering, and the viewing angle is near 180°. Therefore, It's very suitable for reading.
O-paper Vs. paper
Compared to a traditional LCD display (LEFT) , the O-paper display(RIGHT) is easily readable in sunlight.
The O-paper display has higher contrast ratio, reflectance and viewing angle than TN LCDs.
Compared to LCD displays, the O-paper displays have obvious advantage in thickness and weight, and due to the polymer film based structure, it's flexible in shape and size. What’s more, O-paper is durable and reliable. The flexibility feature of O-paper enables its various application, even for some extreme requirements that other types of display technology cannot meet.
The ultra-thin and flexible O-paper display
Thanks to the ultra-thin and flexible feature, the O-paper can be used on the smart card as a display showing balance and transaction record information.
The O-paper display is energy efficient due to two advantages it has.Frstly, it doesn't use a back light which consume most power,but rather, it mimics the picture by reflecting ambient light. Secondly, it's bi-stable, which means no power is needed to hold a static picture. This makes the O-paper display consume much less power than conventional displays, such as LCD displays. We know that less power consumption means longer lasting battery life. Therefore, O-paper displays are highly suitable for the products which are limited to the size or require extreme battery condition.
The bistable O-paper display
The power consumption of O-paper is so low that it can be powered by a solar cell battery.
