Hello experts,

Is there any method to keep the POM tilt in ON state?

Unfortunately they are not designed that way. They are hardwired to land in the off state.

Are you wanting to use the optical path in the reverse direction?

Hello Fizix,

Indeed, we use the optical path in the reverse direction. So the On state POM will make stray light in the optical system.

Alex,

Is there a compelling reason to use the opposite direction?

The only option is to sacrifice a border of active pixels that you use as your own custom POM and make sure that your overfill does not reach the actual POM.

Hello Fizix,

Can we adjust the tilt angle(17°）with firnware? For instance, some colum the tilt angle is 16.8°; and some other column the tilt angle is 17.2°。

Hi Alex,

We may have to answer this come Monday, as TI is currently on holiday, and many key members (such as Fizix) have taken time off.

Thank you for your patience,
Michael Ly

Alex,

The tilt angles are fixed by mechanical structures and are not programmable in any way. Any variation in tilt angle is due to production variations which is already comprehended in the +/- specification.
