VarTech Releases New and Improved Series 3 All-Weather, All-Terrain, Submersible LCD Models
VarTech has released its 3rd generation series of Submersible, All-Weather, All-Terrain LCDs with screen sizes of 8.4", 10.4", 12.1", and 15.0".
Improvement Overview:
o Improved LED backlighting
o Improvements to the optical stack
o Improved mechanical design
Improved LED Backlighting:
Our newly released advanced LED Backlight technology utilizes the very latest in LED semiconductor technology and allows us to more precisely control the brightness of specific areas of the screen. True backlight luminance has been increased without compromises to thermal dissipation, power consumption and life expectancy. The results are a dramatically enhanced contrast with extended brightness and dynamic range.
Other improvements due to the new LED backlight technology are:
o Color stability through active feedback
o Adjustable white point in backlight
o Infinite dimming without color shifts
o Motion blur reduction
A VarTech LED backlight panel enhances the viewing experience of LCD display by providing better color, dynamic backlight control and VarTech's LEDs are environmentally friendly and safe.
Improvements to the Optical Stack:
VarTech's latest proprietary Optical Stack Enhancement (OSE) further advances the performance of the electronic LCD displays by making them brighter, clearer, whiter and more colorful. The difference, quite literally, must be seen to be believed.
As light passes through a liquid crystal display, much of it can be absorbed along the way to the viewer. In fact, in a typical LCD display a theoretical maximum of only 16% of the backlight's potential is realized, in practice, this number is much lower at 8 to 10%.
The new film enhancement technology is a unique optical design which boosts efficiency of the backlight's light utilization and minimizes the surface reflection of ambient light. The result is a transmissive enhancement that features higher contrast and a wider range of colors, even in bright outdoor light, than traditional reflective LCDs. This is accomplished by:
Recycling what would be wasted off axis light and then redirecting light towards the viewer;
Reflecting and recycling polarized light which under normal circumstances 50% of the backlight output would have been absorbed into the LCD and subsequently wasted;
The integration of an advanced polarizing film which can also make LCDs background whiter and brighter. This new film type offers increased reflective properties while maintaining transmissiveness. It nearly doubles reflected brightness across the complete viewing range which reduces the need for driving the backlight higher and brighter therefore extending the life expectancy of the LED backlight system and reducing battery charge.
Finally, the use of a multilayer, ultra-high reflectivity, mirror-like optical enhancement film that is used as a very efficient light guide and cavity reflector with a reflectivity of 98.5% across the visible spectrum which provides a brighter more efficient display.
Improved Mechanical Design:
New IP68 (NEMA 6P) Fully-Enclosed, Submersible design constructed of a Rugged Machined 6061 T6 Aluminum Enclosure.
Improved user controls: no more membrane but rather now sealed momentary push-button switches designed with a smooth tactile feel. These switches are sealed to IP68 standards with expected life of 500,000 cycles.
