A circuit design method based on a split type. A guide slot on a bottom surface of an integrally designed input/output display end and a guide slot on an upper surface of an integrally designed power supply layer form an insertion cavity of an SIM smart card, a top surface of the integrally designed input/output display end is alternatively provided with a lens of an exhibition camera, and a front surface thereof is provided with a projection device and a circuit assembly. The projection device and the circuit assembly achieve display and imaging by means of a physical keyboard on the surface of the integrally designed input/output display end or a virtual keyboard of an AMOLED flexible display screen, so as to output a projected image for displaying. The upper side and the lower side of the SIM smart card are respectively provided with guide slots corresponding to the guide slots forming the insertion cavity, the upper-side guide slot being used to receive antennas, and the lower-side guide slot serving as a power switch and supplying power for the connected parts through a bus, thereby implementing data exchange among the parts. The insertion cavity and the guide slots of the SIM smart card can be applied to the circuit design of the computer, notebook, tablet, and mobile phone in the current hardware condition, so as to reduce incompatibility therebetween, and implement circuit universal replacement. |
