Abstract: A display surface for presenting information in tactile form by means of a grid-shaped array of tactile elements. It can be selectively caused to project into the space above the display surface by using lifting elements. According to the invention, there are a number of line slides (8) corresponding to the number of lines of tactile dots, and a number of column slides (3) corresponding to the number of columns of tactile dots. On the line slides a part (9) is allocated to each lifting element (7) in such a way that the lifting element is fixed in the plane of the line, although it is movable in the plane of the column. Similarly on the column slides a part (4) is associated with each lifting element to shift the latter in the plane of the column.
