Clarification on Time-of-Flight Cover Glass

Hi, 

 

I was reading @John E KVAM excellent post on Time of flight sensor glass:

https://community.st.com/t5/mems-and-sensors/time-of-flight-cover-glass/ta-p/49259

and this documentation

https://www.st.com/content/ccc/resource/technical/document/application_note/group0/9d/93/be/33/13/be/46/19/DM00326504/files/DM00326504.pdf/jcr:content/translations/en.DM00326504.pdf

 

And was just wondering, how important is the IR coating:

Our application will have a large sheet of glass, shared by a display (see image for reference)

And it would be cost prohibitive to IR coat the whole glass. For reference the glass will be ~ 1.1 mm thick. 

Is this likely to cause problems?
