Sony Single Wire Interface Technology Developed

Sony is working on a new technology that will allow facilitate both power and data transmissions through a single cable. The current method to connect up to an LCD screen for example is to use a series of cables in a ribbon format.

This technology enables the internal wiring of a mobile device to be streamlined through a single cable (copper wire). Conventionally, the video, audio and control signals as well as the power transmission were spread out over several dozen cables within the movable mechanisms of mobile devices, such as hinges or rotating parts. Sony aims to promptly implement this technology to improve design flexibility, reliability and durability for mobile devices with movable mechanisms.

Reasons for creating this technology is down to smartphones getting more advanced. By saving space with cables and squashing the signal down a a single wire, the problem of breakages is lowered. With higher resolution screens being launched all the time, more wires are also needed to get the signal to them. If Sony uses the technology it has created, even the higher resolution screens could use a single copper wire.

Sony’s newly-developed ‘single wire interface technology’ has achieved bi-directional transmission of several kinds of signals, including video, audio and control signals, by using time division duplex and multiplex. In addition, the DC power is supplied on the same signal cable. Sony’s unique encoding technology with DC balance enables both DC power supply and high speed data to be transmitted within a limited frequency bandwidth.

It isn’t clear when the technology will start being used, but Sony is keen on pushing it out quickly. More details can be found over at Sony.
