The Result:

Our team worked with a major LCD maker and their engineering team to determine the best base LCD that would meet this application requirement. We designed a high brightness LED backlight system and changed the inside films that enabled a measurable brightness reading of 1500 nits but did so at low power and heat so we did not contribute to the heat gains inside our customers unit. Our custom backlight driver solution enables a very wide and smooth dimming of the backlight down to 1 nit of measurable brightness, perfect for nighttime usage.

Our custom touch panel was designed with high temperature, UV resistant materials and an Anti-Reflective front surface to further support outdoor viewability. With touch controller firmware fine tuned not to react to water droplets, support glove and finger use, the touch panel solution was properly designed for this application.

A full optical bond of the touch panel to the LCD was the logical assembly method to reduce reflective surfaces, increasing all light viewability, adding a layer of durability and eliminating the possibility of condensation build up between the LCD and touch panel.

We were able to meet the overall demand of this project with an understanding of the challenges, knowledge and great experience of the right materials and application techniques that would enable the use of display based solution in this harsh application.
