Electronic Paper Screen Module

Abstract

An electronic paper screen module, including a substrate provided with a first light-transmitting portion; a circuit board, at least part of which is stacked with the substrate; and a light-emitting element disposed on the circuit board and located opposite to the first light-transmitting portion, so that light emitted by the light-emitting element can pass through the first light-transmitting portion from one side of the substrate to the other side facing away from the circuit board. The present disclosure solves the technical problem that the size and the cost of the electronic paper screen are increased due to the disposing of an LED lamp.
