Description
Technical field
The present invention relates to braille display application technical field, especially a kind of method and display device showing braille.
Background technology
Traditional blind person book protruding in the generation of hard paper upper punch pressure is with high costs, be easy to the reading machine meeting scarcity that the shortcomings such as damage cause blind person, make braille utilization rate low, today of humanistic care is more and more paid attention in this society, research and development one really can accept use by numerous blind persons, improve blind person reading theory and population of reading has become a vital problem.
Prior art is difficult to the productive life needs meeting people, in order to solve above-mentioned Problems existing, the present invention proposes the advantages such as a kind of cost is low, volume is little, lightweight; Change the concave-convex sense display mode of original braille for vibration sense display mode, have employed piezoelectric ceramics as vibrating elements; Unique vibrations chamber structure amplifies amplitude to distinguishable amplitude, reduces sense of touch tired out, be suitable for long-time reading while power saving; Mainly in blind person disadvantaged group, improve piezoelectric type braille display device and the method for blind person's reading environment.
For realizing this technical purpose, the technical solution used in the present invention is: a kind of method and display device showing braille, comprises top panel, lower panel, vibrations chamber, piezoelectric shock generator, contact and drive circuit board; The hole that on described top panel, a lot of applicable contact of hollow out is put into; Described contact and top panel combine and together constitute display panel; Described contact is arranged on pressure vibrations upper end, chamber; Described lower panel is arranged on drive circuit board, and vibrations chamber is connected with drive circuit board by lower panel.
As further technical scheme of the present invention: described vibrations chamber and the piezoelectric shock generator be placed in vibrations chamber form vibrations unit jointly.
As further technical scheme of the present invention: described vibrations chamber is metal cavity structure, and it is an electrode of piezoelectric shock generator; Simultaneously due to bottom fix can amplification piezoelectric vibration generating arrangement produce be vibrated to contact, make contact chatter distinguishable.
As further technical scheme of the present invention: described piezoelectric shock generator is made up of pressure point pottery and two electrodes, vibrations chamber is as an electrode, the other one side of piezoelectric ceramics is as a pole, at the sine wave of two-stage 5V to 20V in addition, and frequency is between 125hz-235hz, distinguishable vibration can be produced, and seismaesthesia is smoothly and not violent, be suitable for long-time reading, reduce energy consumption simultaneously.
Compared with prior art, the present invention has following beneficial effect: this piezoelectric type braille display device,
One, solve the problem of braille text importing difficulty on an electronic device; The power consumption of piezoelectric ceramics is lower, can use powered battery, and very large optimization has been done in the mobile for blind person's electronic reading device.
Two, can micro, piezoelectric ceramics can be made into quite little parts, and device, on panel, even without the need to shaking chamber, directly lies in panel surface.To such an extent as to blind person's electronic reading device can be microminiaturized, can make the mobile of blind person's electronic reading device.
Three, with low cost, piezoelectric ceramics, and the cost of miscellaneous part is very cheap, the cost of whole blind person's panel is considerable; Also mitigate the financial burden of these disadvantaged group of blind person simultaneously; One-piece construction is simple, novel in design, practical, is easy to promote the use of.
