Abstract
A device and associated PCB structure are provided in which a dedicated area of the device substrate is patterned, so that it can be contacted by a readout arrangement of the PCB. The pattern comprises an arrangement of contact regions. Interconnections and open circuits are used to encode information. A dotted contact area of the PCB is used to probe the pattern, and relay this to a driver which can then derive information about the type of device being driven. The driver can thus be controlled accordingly.
Claims16
A device for connection to a device driver, comprising:
- a substrate;
- a patterned area of the substrate comprising a set of device contact regions, wherein a network of interconnections is provided between the device contact regions, which network encodes information concerning the characteristics of the device
- wherein the patterned area comprises a set of pairs of device contact regions, wherein a short between a pair encodes one binary value and an open circuit between a pair encodes an opposite binary value.
A method of driving a device, comprising:
- testing for interconnections between a set of device contact regions on a substrate of the device, thereby to determine a network of interconnections provided between the device contact regions, which network encodes information concerning the characteristics of the device;
- and
- driving the device using a driver which is controlled in dependence on the encoded information;
- wherein the testing comprises connecting the device contact regions to contact pads of a PCB, and coupling the PCB to a device driver.
