Abstract

The invention provides a basic display driving circuit driven by a conductive wire type artificial neuron, a conductive wire type artificial neuron component used for the display driving circuit is of a sandwich structure and sequentially comprises a bottom metal electrode layer, an insulating layer and a top metal electrode layer from bottom to top, the bottom metal electrode layer is made of an inert conductor material, and the top metal electrode layer is made of a conductive material. The insulating layer is made of an ion-migratable insulating material, and the top metal electrode layer is made of an active metal material. The light-emitting module is composed of a first light-emitting device, a second light-emitting device, a third light-emitting device and a fourth light-emitting device which are all unidirectional conductive devices.
