LCD flat panel displays engineered specifically for
use in direct sunlight or very high
ambient light conditions. These robust systems are designed
to survive 24/7/365 constant usage throughout demanding
applications where rain, snow, high humidity, vibration,
dust, dirt, and/or extended operational temperatures
who merely add higher wattage bulbs to the backlight
box certainly make the screen brighter. But the inherent
contrast ratio between white and black will only ‘washout’
and make the video image unreadable once an LCDs brightness
level is driven up beyond the panels designed capabilities.
More ‘nits’ is simply a “selling point”. The true sunlight
readability of a display is mostly dependant on the
amount of light that is being reflected off the display.
Increasing the luminance level is important, but definitely
not the driving factory. VarTech meets this problem
head-on with its proprietary Optical Bonding (VBOND)
process. Additionally, boosting the intrinsic light
utilization and efficiency of the backlight's light
is crucial. Simply adding brighter bulbs doesn’t address
this situation. VarTech takes another step toward achieving
the Most Sunlight Viewable systems on the market today.
We incorporate a unique transmissive film enhancement
technique to the optical stack (our OSFE).
