The invention relates to the technical field of blind person touch display, in particular relates to a touch display device which comprises a base, a contact and a driving structure corresponding to the contact, wherein the driving structure is arranged on the base and comprises a driving part and an eccentric wheel, the outer circumferential surface of the eccentric wheel is in contact with the contact, and the driving part can drive the eccentric wheel to rotate so as to drive the contact to do linear reciprocating motion. The driving part drives the eccentric wheel to rotate around the rotating center, and in the rotating process of the eccentric wheel, the contact does linear reciprocating motion in the direction perpendicular to the axis of the eccentric wheel, so that reciprocating rising and falling of the contact are achieved. When a plurality of contacts are arranged on the base, traditional braille alphabet can be displayed by adjusting the distance between the contacts, andwhen the braille alphabet display device is used in a large format, graphic display can also be formed, and the device becomes a display for the blind. The eccentric wheel rotating structure controlsrising and falling of the contact, the structure is simpler and more compact, and more electricity is saved in the control process due to addition of a mechanical structure.
Description
technical field [0001] The invention relates to the technical field of tactile display for the blind, in particular to a tactile display device. Background technique [0002] Touch reading is fast and highly recognizable, and it is the most important way for blind people to read and watch. However, the special paper for traditional Braille books is expensive, the production process is complicated, and it takes a long time. Moreover, there are few Braille books published, the variety is single, the information is lagging, the amount of information is small, the volume is heavy, and it is not easy to carry. There is no better form for Braille paintings. These factors lead to the fact that traditional Braille works are far from meeting the needs of blind people. Existing tactile display devices are large in size and bulky, and mostly use electronic components inside, which are expensive and consume a lot of power, making it difficult to be widely popularized and applied.
