Abstract
Most people think that LCD monitors are low or zero in radiation. That is not true. The backlighting uses thousand volts for fluorescence and carries an electromagnetic field. Zero radiation LCD monitors use e.g. clear metallic grating in front of the display viewing area. The main goal of this contribution is optical properties analyze of radiation protected and no protected LCD displays. The analyze evaluates the display viewing angle which is one of the most important indicators for graphic information quality in the Human Computer Interface system.
