Sažetak
The goal of this work is to investigate the interaction between electrostatic field of Video Display Units (VDU’ s) and human head in front of it. Special attention is given to the field at the surface of the face. The finite element model for assessment of the electrostatic field, by solving three dimensional Laplace equation for the electric potential, is implemented. The electrostatic field is calculated for two different faces and then compared with results obtained by the finite difference method. Furthermore, calculation is made for various parameters such as the distance between display and face, size of the display and electrostatic potential of the display. Detailed analysis of the field strength is made on the face of the operator as well as in the space between display and face as a function of display size and distance between face and display. Finally, results are compared with the available international standards and guidelines. The advantage of the presented finite element method is a high resolution.
