The invention discloses a
Braille display and writing integrated electronic module, and belongs to the technical field of read-write auxiliary equipment for blind people. The module comprises a
braille touch, a telescopic driving mechanism, an upper / lower PCB, a magnetic sensor and a shell. The telescopic driving mechanism adopts an
electromagnet and a permanent
magnet which are oppositely arranged up and down to form a bistable structure, and the
braille touch points are driven to stretch out or retract by controlling the electrifying polarity to form a
braille dot matrix; the magnetic sensor is used for detecting a point position state; an induction
electrode is arranged on the upper surface of the module and used for detecting
capacitance changes caused by finger approaching, module-level braille writing input and touch position detection are achieved, and multi-mode interaction is supported. The portable electronic braille terminal is compact in structure and low in cost, has display and writing functions, can feed back touch information, and is suitable for multi-module spliced portable electronic braille terminals. In addition, the invention further provides a universal module-level capacitive touch
interaction device which can be independently applied to various man-
machine interface devices.
