- fig. 5, vedere de sus a modulului tactil rezistiv;FIG. 5, top view of the resistive touch module;

- fig. 6, secțiune parțială prin modulul ferofluidic.FIG. 6, partial section through the ferrofluidic module.

Ecranul tactil, destinat utilizării de către nevăzători pentru citirea de texte și imagini, conform invenției, are un corp 1 al ecranului pe care este prevăzut un ecran 2 tactil care are un strat superior elastic.The touch screen, intended for use by the blind for reading texts and images, according to the invention, has a body 1 of the screen which is provided with a touch screen 2 having an elastic upper layer.

între corpul 1 al ecranului și stratul 3 superior elastic al ecranului 2 tactil este prevăzut un modul 4 tactil electromagnetic, format dintr-o multitudine de elctromagneți 5 de presare, care sunt comandați prin intermediul unei unități de comandă și control, neredată în desene, care poate fi de exemplu un calculator personal.Between the body 1 of the screen and the upper elastic layer 3 of the touch screen 2 is provided an electromagnetic tactile module 4, formed by a plurality of electromagnets 5 pressing, which are controlled by means of a command and control unit, not shown in the drawings, which for example, it can be a personal computer.

Modulul 4 tactil electromagnetic este format din multitudinea de electromagneți 5 de presare, care au o bobină a de acționare și un miez b mobil.Module 4 electromagnetic touch consists of the plurality of electromagnets 5 pressing, which have an actuating coil and a movable core b.

Atunci când unitatea de comandă și control transmite semnale către modulul 4 tactil electromagnetic, miezurile b mobile se deplasează în sus formând litere,When the control and control unit transmits signals to the electromagnetic touch module 4, the mobile b cores move upwards forming letters,

A'2 ο 1 6 - - D ϋ7 Ο 6 - //A'2 ο 1 6 - - D ϋ7 Ο 6 - //

Ο 6 -10- 2016 caractere Braille sau imagini în relief, pe care o persoană cu probleme de vedere le poate detecta tactil.Ο 6 -10- 2016 Braille characters or embossed images, which a person with visual impairments can detect by touch.

într-un exemplu de realizare a invenției, ecranul tactil, destinat utilizării de către nevăzători pentru citirea de texte și imagini, este prevăzut cu un modul 6 tactil rezistiv, care este prevăzut cu o multitudine de rezistențe 7 de contact.
