Sony patents daisy-chained display wiring for car dashboards

Sony describes a method for connecting multiple display components in a line, known as a daisy chain, using a specific type of data connection called a serial peripheral interface. This setup allows a single data source to send information to several screens or panels sequentially rather than requiring separate wires for each one.

Why it mattersThis simplifies the internal wiring in vehicles with multiple screens, potentially making dashboard assembly easier and reducing the number of cables needed inside the car.

In the filing’s own words

A communication apparatus according to an embodiment of the present disclosure includes: a transmission device including a serial peripheral interface; and a plurality of reception devices configured to receive a data signal and a clock signal from the transmission device. The plurality of reception devices are coupled in a daisy chain via a signal line configured to communicate a chip select signal.

What exactly they claim (claim 1)

1. A communication apparatus comprising: a transmission device including a serial peripheral interface; and a plurality of reception devices configured to receive a data signal and a clock signal from the transmission device, wherein the plurality of reception devices are coupled in a daisy chain via a signal line configured to communicate a chip select signal.
