Embodiment Construction

[0022] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0023] Please refer to figure 1 , figure 2 A plurality of groups of holes 100 are formed on the display panel of the electronic book for the blind according to the present invention. Each group of holes generally includes 6 holes arranged in a rectangle for corresponding to a Braille. Multiple groups of holes are arranged in an array on the panel.

[0024] In addition to the above-mentioned display panel, the e-book for the blind of the present application may also include other modules required by existing e-books, such as an earphone jack, a USB interface, a power switch, a page-turning button, and the like.

[0025] More preferably, the Braille e-book of the present application further includes a playback module, so...

Abstract

The invention discloses an electronic book for a blind person. The electronic book comprises a display panel, a plurality of sticks, a plurality of electroactive polymer materials, a current control component, a control component and a braille conversion component, wherein a plurality of holes are formed in the display panel, each stick is arranged below each hole correspondingly, the sticks are arranged on the electroactive polymer materials, the current control component is electrically connected with the electroactive polymer materials, the braille conversion component is capable of converting braille data into received electronic data, the control component controls the current control component to output current according to the braille data, and output current of the current control component enables the electroactive polymer materials to deform so as to let the sticks on the materials to protrude out of the holes. The electroactive polymer materials drive the sticks to protrude out of the holes so as to display the braille, without a complicated mechanical driving and resetting mechanism, convenience of the electronic book for the blind person can be improved by powering on or off the electroactive polymer materials.

Description

technical field [0001] The invention relates to the technical field of products for the blind, in particular to an electronic book for the blind. Background technique [0002] E-books for the blind refer to e-books for the blind, which convert electronically stored data into Braille characters for display. Each character of Braille characters consists of 1-6 prominent basic dots. To display braille characters, it is necessary to solve how to control the raised braille dots. [0003] Existing e-books for the blind, such as the Chinese patent "an e-book for the blind" with the publication number CN102222430A, controls the protrusion of the Braille dot characters through the electrorheological fluid single valve and the drive module. This method must The use of electrorheological fluid single valves and complex drive mechanisms make the overall structure of Braille e-books bloated. [0004] Another example is the Chinese patent "A Braille Tactile Display System" with publica...
