Start-up develops thin Light Paper lighting




US start-up Rohinni light technology has developed in which very small LEDs with ink can be printed in a thin layer on all kinds of materials. The company claims that its Light Paper technology is widely applicable, for example in electronics.

Light Paper In the first implementations of Light Paper LEDs are the size of a red blood cell, together with ink on a printed conductive layer. Over it is still placed a transparent layer to cover the complete assembly. By voltage to put on the Light Paper can light are produced.

The very thin material is pliable and light, can be printed in many forms and can be applied to all kinds of material. Alternatively, it could be easily produced on a large scale. Currently still the company has struggled to bring equal to the LEDs, which may generate less bright spots within a Light Paper. Rohinni wants his own words to try to fix this problem in future versions of its luminous material.

Several companies, including Rohinni not want to reveal the names, Light Paper would already are testing. The technology could be used, for applications in consumer electronics, such as smartphones, and new ways of lighting indoors. Also, the display of brand logos is mentioned.

Compared OLED Light Paper displays would be thinner, the LEDs have a longer life span, better bendable. However, It is still unclear how much the technique used in practice.
