Abstract: This patent describes magnetic Braille cell actuator structures which include Braille pin movement and latching mechanisms. In one example, the Braille pin can be kept at reading position all time by a small force spring and latching of Braille pin can be realized by controlling movement of a latching bar underneath the Braille pin by a combination of electromagnet and permanent magnets working together. In a second example, the Braille pin can be moved between reading and rest positions through the repulsive and attractive interaction between a programmable magnet and a permanent magnet; while the latching of Braille pin is through the jumping and tilting action of the Braille pin onto a latching stage through the horizontal and vertical interactive magnetic forces. The unique magnetic Braille pin movement and latching mechanism enables very low power consumption of Braille display while Braille pin matching the standard spacing.
