Temperature and Humidity Resistant LCD Modules – Display Solutions for Solar Inverter or EV Charging Applications

Application Spotlight, October 2018

LCD display on solar inverter , AZ Displays LCD panelAZ Displays has integrated high-end polarizers and liquid crystal fluid into a select list of LCD monochromatic modules, capable of passing stringent 85C /85% RH (Relative Humidity) 1000 hours reliability test conditions. These LCD modules have an enhanced operating temperature of -30C to 80C.
At low temperatures, the liquid crystal fluid maintains its viscosity, allowing the IC to refresh the data logic without any latency in the response time. At the high extreme of the operating temperature spectrum, the polarizer and adhesive materials are able to withstand the heat without warping the film and damaging the optical performance of the LCD module.
Application Example: Solar Inverters and/or EV Charging Stations
In the recent past, AZ Displays has supported a range of design activities in the Solar application and Electric Vehicle charging markets.
These applications call for compact and robust designs at competitive prices, which are supported by AZ Displays with the following LCD modules:

Series Description
Viewing Area
ACM1602KW 16 x 2 alphanumeric LCD module 64.5 x 16.4 mm
ACM2004D 20 x 4 alphanumeric LCD module 76.0 x 25.2 mm
AQM2416 240 x 160 dot matrix LCD module 78.5 x 47.5 mm

In addition to meeting the stringent quality requirements to withstand high temperature and humidity exposure, our displays also support “smart management” features, in form of a visual interface designed to help control the overall PV or EV application.
