i3 window is the first company to offer full sunlight readable screens in the UK. We have selected a professional DID LCD panel, engineered for rugged and prolonged use while exposed to sunlight, especially UV rays. Our system uses various technologies and engages many elements in order to achieve high brightness (700 - 1.500 nit), contrast (2.500:1 - 4.000:1) and low reflectivity (less than 1%).
An outdoor display screen on a sun-readable LCD should be bright enough so that the display is visible under strong sunlight. Second, the display contrast ratio must be maintained at a 5 to 1 ratio or higher. A truly sunlight readable LCD display is typically considered to be with 700 nits or greater screen brightness with a contrast ratio greater than 5 to 1.
The combination of a professional LCD, with HVAC and antireflective glass makes it possible to see a clear picture under direct sunlight. The glass used in i3 window screens has a special anti-reflective coating, which minimizes the sunlight reflection rate below 1%.
Contrast ratio is the ratio of luminance between the brightest "white" and the darkest "black" that can be produced on a display. Contrast ratio is another major determinant of perceived picture quality. If a picture has high Contrast ratio, you will judge it to be sharper and crisper than a picture with lower Contrast ratio.
Luminance is the scientific term for Brightness which specifies the visual brightness of an object. Luminance is specified in candelas per square meter (cd/m2) or nits. Luminance or Brightness is a major determinant of perceived picture quality in an LCD. The importance of luminance is enhanced by the fact that the human mind will react more positively to brightly illuminated screens and objects. Users are typically more drawn to brighter displays that are more pleasing to the eye and easier to read.
An important fact of LCD display operation is of dependency of performance with levels of heat and humidity. This is extremely important, especially for outdoor LCD systems. i3 window delivers optimal environment for LCD operation within the enclosure: Constant optimal LCD and electronics temperature range between +20°C to +25°C & no air born particles entering the system.
