The Prisma-4k-Controller is specified for a temperature range of -20 to +60°C and is equipped with a temperature sensor. At a temperature below -20°C the controller switches on the backlight one minute before the TFT display to reach the necessary operating temperature. At outside temperatures above -20°C, the backlight and TFT are switched on simultaneously. From 50°C case temperature, the TFT-controller halves the screen brightness and activates a fan signal so that the target temperature of 60°C is not exceeded.
Via an integrated brightness sensor, the Prisma-4K-Advanced also regulates the display brightness to match the ambient brightness. This ensures a perfect and glare-free readable display at all times while optimizing power consumption. With a wide viewing angle of 89° from all directions, the display easily delivers a true color image even when viewed from the side.
Except for the fan, the outdoor kit solution includes all necessary accessories and can be put into operation immediately. Samples will be available in June. Please contact us.
