DLP4710LC: DLP4710LC Tilt orientation question

Part Number: DLP4710LC

Hi,

I draw a graphical representation (see Figure1) to illustrate the tilt orientation between the micro-mirror and the DLP4710LC backplane after referring to the datasheet of DLP4710LC. It illustrates that the tilted axis is NOT coplanar with the DLP4710LC backplane. Is this correct?

If figure1 is correct, then what’s the logic behind illustrating the tilted axis with red dashed line that does not connect a vertex to another vertex? (Fig.2)

 

Thank You!

    This is correct. Your graphic demonstrates the concept well. A short animation for this same concept can be viewed in the How To Display Video & Control Light Using DLP®  Technology video from 0:45 - 1:00.

    The red dashed line shows the pivoting axis. This is the axis of the mirror that has minimal movement around which the mirror movement takes place. In other words, this is the center of the mirror movement.
