Electronic devices

Abstract

A novel electronic device is provided. The electronic device includes a housing and a display device. The display device includes a first layer, a second layer, and a third layer. The first layer houses a driving circuit section, a weight switching section, and a peripheral computing circuit section. The second layer houses a first pixel circuit section, a second pixel circuit section, a memory circuit section, and a summation circuit section. The third layer houses a light-receiving element and a light-emitting element. The memory circuit section has the function of maintaining weight values ​​set in the summation circuit section. The summation circuit section has the function of performing a summation operation on the weight values ​​set by an analog current signal and an input value based on a signal obtained from the light-receiving element, and outputting an output current corresponding to the summation operation. The peripheral computing circuit section has the function of performing calculations using the output current and outputting an output signal corresponding to the calculations. The weight switching section has the function of controlling the memory circuit section and updating the weight values ​​set in the summation circuit section according to the output signal.
