The present invention discloses a layered electro-magnetic refreshable braille display device and braille reader. The layered electro-magnetic refreshable braille display device includes three layers of braille display modules and a touch panel. Each braille display module includes 5 plates and a plurality of tactile pin driving mechanisms for driving the 'up' and 'down' of the braille dots. One or more lines of braille cells are arranged on the touch panel. Each line of braille cells displays a plurality of braille characters. A microprocessor is connected to a braille translation module, a voice playing module and an interaction controller respectively, wherein the interaction controller is connected to the braille display device, to form the braille reader. This device can display one or more lines of braille characters by relying on the electro-magnetic principle. It boasts real-time refreshing of the braille, synchronization of braille display and voice playing.
