The Japanese electronics company Omron is developing a new technique for thin layer of backlit LCD screens of mobile phones.

Its subsidiary Omron Precision Technology has developed a light guide plate finer with a new manufacturing process. Usually, this piece is made with injection molding or a transfer of heat, but here the thin layer is formed by extrusion. The shape of the guide obtained is such that it acts like a lens at one end to bend light rays from the LED (light-emitting diodes).

The result is a light-guide of 0.23 mm thick, or half the thickness of those of liquid crystal displays current firm.

Combined with a layer of dispersion and a layer of prism, the light-guide system forms a backlight with a thickness of 0.59 mm record for an LCD screen mobile phone * 3 inches diagonal (7.62 cm ). This thickness represents a 30% relative to the backlight the thinnest currently produced by Omron.

This system backlight can be distorted, which will allow Omron to include it in the near future to its LCDs (Liquid Crystal Display) flexible.

Omron plans to launch mass production of the new LCD screen next spring.
