One of the most compelling claims made by Screen Technology is that their unique ITrans display technology is fully viewable in bright sun or artificial light. This claim has now been verified to the demanding standards of the National Physical Laboratory (NPL) after a number of tests were carried out on brightness and contrast levels.

An ITrans 62” screen underwent four days of vigorous testing by the highly regarded independent standards and test house in Teddington, Middlesex. The results concluded that even under the extreme test of 110,000 lux, equivalent to a bright day in the Sahara, the screen still gave excellent image colour, brightness and contrast and so remained fully viewable.

ITrans achieves this impressive performance through the combination of two key features – high brightness and sunlight rejection technology.

Carefully designed backlights give 2000 cd/m² of illumination, whilst the unique ITrans tile gives the display its unique sunlight rejection qualities. Each ITrans fibre throws the desired image light forward, however undesirable sunlight which hits the front face at an angle is steered away into contrast enhancing strips before it hits the underlying LCD panel. LCD’s without an ITrans tile would suffer from surface reflections, significant loss of contrast (so called ‘wash out’) and in extreme cases the energy from the sunlight can cause the LCD panel to black out completely. Only with ITrans ‘sunlight rejection technology’ can these problems be avoided.
