A braille display, belonging to the technical field of blind people reading devices, uses a memory alloy material to realize recessing and protruding of a braille point array of the braille display. The braille display is mainly composed of any number of braille recessing-protruding dot arrays, each of which includes several individual point locations, an outer frame and signal boards. Each of the individual dots comprises upper and lower telescoping members, an upper conductive connecting member, an intermediate conductive connecting member, a lower conductive connecting member, external sleeve locks and guide rods. The recessing-protruding change of braille points is realized through specific connection of various specific components. By using the braille display, the endurance capability is improved, and the cost is reduced. Moreover, since the braille display has a relatively small volume, the braille display can be applied to a mobile portable device or a wearable device.
