3.2 Technology

The monitors are based on LCD Super MVA technology. The benefits of this technology are wide viewing angles, fast video response and high contrast ratio.

MVA stands for Multidomain Vertical Alignment.

3.2.1 Principle of LCD technology

These are the basics used in LCD technology:

•Light can be polarized

•Liquid crystals can transmit polarized light.

•Liquid crystals align themselves when a voltage is applied.

•Liquid crystals change the light's plane of vibration to match their own angle.

There are multiple operating principles of LCD's; one of them is the Multidomain Vertical Alignment which – not surprising – is based on the Vertical Alignment (VA) technology.

With this operating principle, the LC molecules are completely perpendicular when no voltage is applied, and thus they don't change the polarization of light. Light simply passes the LC, and is blocked by the front end polar- izer (since this polarizer is rotated 90° against the back end polarizer which allowed the incident light to pass).

Because the blockage is complete, the quality of black produced this way is excellent!

When voltage is applied, the molecules shift to a horizontal position, producing a white image: the polarization of the light is changed, and light can pass the front end polarizer.

Since the LC molecules are simply switched between vertical and horizontal alignment, response speeds are very fast.

As a further development of the VA technology, with MVA technology the LC cell is divided in sub domains where the molecules are oriented in opposite direction. This widens the viewing angles and enhances the performance.

The following picture shows the basic principle of VA technology:
