Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] See figure 1 , an electronic book for the blind, including a display module 11 for displaying Braille characters, an array valve module 12, a drive module 14 and a control module 15; wherein:

[0033] The display module 11 includes at least two rows of display units for displaying Braille characters, and each display unit includes basic points for displaying Braille characters. Since different countries and regions may have different requirements for the spacing between the basic dots of Braille characters, the display of Braille characters complies with the corresponding standards.

[0034] The array valve module 12 is placed under the display module, and the array valve module includes several valve groups, and the valve groups correspond to the basic points on the display module one by one. The on-off is used to control wh...

Abstract

The invention provides an electronic book for blind people, which comprises a display module used for displaying Braille characters, an array valve module, a driving module and a control module, wherein the display module comprise basic points for displaying Braille characters; the array valve module comprises a plurality of valve sets, wherein on-off of the valve sets is used for controlling projection and not projection of the corresponding basic points; the driving module is used for generating power for the display module to display Braille characters; the control module is used for controlling the on-off of corresponding valve set of each basic point by switch tube through longitude control line and latitude control line according to the received electronic data, and controlling the driving module to work. By employing a technical scheme of the invention, when displaying multiple lines of Braille characters, quantity of required switch tube is greatly reduced, production cost of the electronic book for blind people is greatly reduced. The electronic book for blind people is convenient for large scale production, which facilitates visual impairment people to enjoy the pleasureof reading.

Description

technical field [0001] The invention relates to an electronic book for the blind, in particular to an electronic book for the blind based on electrorheological fluid. Background technique [0002] With the popularization of computer and network technology, the information age has come. However, for the visually impaired, they mainly use electronic information through listening, and it is difficult to enjoy the joy of reading. [0003] In order to establish a harmonious society with "information barrier-free" and meet the reading needs of the visually impaired, it is necessary to convert electronically stored data into Braille character display, that is, e-books for the blind. Each character of a Braille character is arranged in a rectangle with 6 dots by 1 to 6 raised basic points. To display Braille characters, it is necessary to solve how to control the protrusions of the basic dots, the size of the e-book for blind use, and heat dissipation And other issues. [0004] In...
