My screen is broken, phone still works. Can I remote view the screen?

Hi, I dropped my phone just right and damaged the top of the screen by the light sensor. The cracks propagated throughout the screen, over the coarse of 1 day the screen lost all visibility (as the liquid crystal leaked?). The touch doesn't work but the pen still does so I was able to control the phone as long as I could view some of the screen to activate screen mirroring and view on my TV. But now that the screen is completely black I can't see anything to activate screen mirroring. Is there any way to view the screen, HDMI or force to mirror through a remote of some kind? We will most likely scrap the phone but I need the data off of it. Any suggestions would be awesome.

Thanks -KB
