Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a braille point display device applied to auxiliary interactive equipment for the blind. Background technique [0002] According to statistics, the number of visually disabled patients in my country reached more than 17 million in 2019, which is equivalent to one "walker in the dark" for every 80 people, and among these "walkers in the dark", there are even people without healthy hearing. There are huge difficulties in obtaining and exchanging information. Due to the defects of visual function or auditory function, blind people receive external information differently from ordinary people, and they mainly make up for it through tactile means. Braille is an information symbol formed by arranging contacts in a dot matrix. Blind people can perceive and receive Braille information through touch. [0003] With the rapid development of modern science and technology, a ser...
