Yup, sometimes by accident and sometimes by design. The system is programmed to start shutting-off non-essential electrical drains if it senses voltage is getting very low, e.g., it will disable the seat heaters. While I doubt that it is purposely shutting down the display for this purpose, I can tell you that when my battery was going bad, odd things started happening, like the HVAC fan not working for two days, the display coming-up solid red, etc.
