Abstract
Брайловият дисплей представлява решетка (14) с отвори и поставена под нея върху основа (1) матрица от електромагнити, състоящи се от външен магнитопровод (2), намотки (3 и 5) с магнитопроводи (4 и 6), и подвижно в зоната между намотките немагнитно тяло (7), което носи немагнитна игла (9) и аксиално намагнитен постоянен магнит (8) с феромагнитни шайби (10 и 11) от двете му страни (отгоре и отдолу), съответно с цилиндрични полюси (12) за магнитопровода (4) и феромагнитна шайба (10), и с конични полюси (13) за магнитопровода (6) и феромагнитната шайба (11), като над електромагнитите е поставена решетка с отвори (14) (Брайлов дисплей), през които преминават иглите (9). Брайловият дисплей намира приложение за създаването на помощен текстово/графичен компютърен интерфейс при хора със зрителни увреждания.
