It is hard to think of an ITD sunlight readable touch screen that does not suffer from some form of deterioration. It seems that as soon as they are installed the problems of aging start to show. That is not surprising when one considers the fact that the human eye has a difficult time adjusting to poor quality displays. In addition, the sunlight causes the phosphor layer in the display to become unstable and degrade over time.
Fortunately ITD sunlight readable touch screen products can overcome many of these difficulties and provide a superior level of performance. The key is to know exactly what types of lighting conditions are prevalent where the ITD system will be installed. The most important consideration is to ensure that the display hardware itself provides a sufficiently bright display under sunlight. In many cases fluorescent lighting may be the only option, but even with fluorescent lighting there are inherent weaknesses that must be addressed. If fluorescent lighting proves problematic for any reason it is often possible to upgrade to a standard LCD flat panel monitor.
One type of outdoor advertising display that commonly requires ITD sunlight readable touch screen displays is a digital sign. Digital signs are generally used to offer advertisements in the form of billboards or text. Because the signals are analog, they are often less susceptible to deterioration from the lighting conditions experienced in the area where they will be placed. In addition, because the digital displays do not require display devices such as CRTs or liquid crystal displays they can be more easily setup and operated in unfavorable outdoor conditions.
Another type of outdoor display often requires ITD daylight viewable monitors. These products are often necessary for outdoor billboards and other forms of digital signage. With sunlight readable displays the words on the display do not have to be faded due to sunlight reflecting off the monitor. Even in areas of very poor sunlight, ITD daylight viewable monitors can often display the words clearly enough for those in the area to read them.
It is important to note that ITDs have many advantages over traditional touch screens. The most obvious advantage is that the sign is more touch sensitive than other types of outdoor displays. Touch screens have a short life span and must be replaced every few years due to chipping. In contrast, ITDs last for decades if not longer and do not have to be replaced. Touch sensitive outdoor monitors often utilize resistive or capacitive sensing technologies. Resistive displays allow a lighter touch than Capacitive sensing technology which results in a smoother and more responsive screen.
The final category of ITD sunlight readable monitors are LED. LED are considered the best for representing light in all lighting conditions. Because LED displays can be viewed outdoors in all lighting conditions, they are often used outdoors for signage. LED lcd displays have a sharp crisp resolution and a wider color spectrum when compared to regular LCD displays. Many businesses utilize an ITD type of display outside of the workplace for creating an easy to read graphic.
