Patent ID: 8588558

Claim:
A circuit for a cell phone comprising: a flexible circuit having an optical waveguide embedded therein; a video processor coupled to a first device via a first printed circuit board, the video processor configured to output a first electrical signal to the first device, the first device attached to the flexible circuit and configured to convert the first electrical signal to an optical signal, the first device positioned to emit the optical signal to an input end of the optical waveguide, wherein the flexible circuit is coupled to the first printed circuit board via a first connector at the input end of the optical waveguide; a second device attached to the flexible circuit and configured to convert the optical signal into a second electrical signal, the second device positioned to receive the optical signal from an output end of the optical waveguide, wherein the flexible circuit is coupled to a second printed circuit board, via a second connector, at an output end of the optical waveguide; a video display coupled to the second device and configured to receive the second electrical signal; and a test pad positioned on the flexible circuit separate from the first connector and the second connector, the test pad configured as a tester interface to test the flexible circuit during manufacturing separate from using the first connector and the second connector.
