Braille display is a display for the blind, but instead of LEDs it is composed of a matrix of dots that are mechanically operated with rising and falling capability. The matrix of one dot (or pin) consists of 8 dots, placed in 4x2 form. The combination of the dots with some risen and some in passive mode, i.e., fallen, gives us a chance to express all the possible ASCII symbols. There is a challenge among the scientific and production personnel to construct the cheapest and more reliable system for the blind to gain digital information and our team of engineers is a part of it and this thesis work is only a part of a bigger project carried out by.
