The Technical

LCD displays on EV charging station are custom made according to requirements like installation location, size, brightness, weather proof etc. They generally have following difference, when comparing with consumer or industrial LCD screen.

  • High brightness - most EV chargers are installed outdoor, TFT LCD screen needs to be a lot brighter than indoor used.
  • Low power consumption - high brightness usually means higher power consumption, EV charger screen needs to use high efficient LED backlight, to save energy and reduce heat.
  • Wide working temperature - outdoor temperature can be very cold and hot, charging process generates heat too. Therefore, the TFT LCD module needs to put up with a wide temperature range. 
  • Weather proof - nature throws all kinds of weather conditions on to charger. The LCD screen needs to endure rain, dust, UV light and external impact.
  • High electromagnetic compatibility - charging work brings serious electromagnetic interference. TFT LCD module has to work normally in such environment.
