"PLACE IN THE SUN" - OPTICAL ENVIRONMENTS

Most computer users have experienced direct sunlight causing viewing problem, even for office computer users. The indoor user has options to shade or change the computers position to lessen the effects of sunlight and reflections, whereby improving the readability of the display. In many vehicles this is not an option as direct sunlight or reflections are nearly impossible to avoid.

Designers of mobile computers struggle with the trade-offs between daylight requirements and power/heat consumption of the unit. In addition, the display must offer a wide viewing angle and pleasant sights both in direct sunlight and in complete darkness.

Viewing from a small angle is crucial in order to look well
Wide viewing angles and significant increases in backlight technology have helped us make some of the best "daylight viewable" displays in the industry. Brightness levels are 2 to 3 times higher than standard laptop computers.

A wide viewing angle is important in many applications such as public safety, information kiosks, machine guidance and medicine. Certain applications require several people to view the screen at once, making a wide viewing angle critical. Viewing angles for our screens are normally 120 degrees

Night and day
Anti-reflective filters and high brightness backlighting makes our computers ideal for outdoor use. Direct sunlight, high or low ambient lighting is not a problem. We can incorporate transreflective technology into our computers resulting in “the stronger the light, the brighter the image.” These screens use reflective light in bright environments and transmissive backlighting in dark environments.

Dim ability
Another difficult task in display control is dimming because it is very difficult to obtain even brightness levels in all dimming levels across a display. This is the reason why many other computers have only one or two levels of dimming capability. The JLT solution supports dimming with 64 levels of luminance from complete dark to full bright.
