Other Parts Discussed in Thread: DLPC3437, DLPDLCR3310EVM, DLP3010, , DLP4710
The device datasheet specifies a mirror array of 1368x768 pixels, and in other messages in the forum it is stated that each mirror is used to display two unique pixels, thus allowing a true 1920x1080 display. For some of your DLP products, people obtain higher display resolution than the number of mirrors by using beam/pixel shifting devices, and indeed on the 3310 eval board schematic [sheet 14, connector J5] there seems to be a driver circuit for such a device, but I did not see one mentioned in the related documents.
Question #1: Does the 3310 eval unit use a pixel/beam shifter device, or does it double the pixels using only its own mirrors?
Question #2: If a beam/pixel shifter is required and used in the demo, could you disclose the vendor and part#?
Question #3: Is this pixel doubling performed in the DLPC3437 devices, or in the very expensive (and currently unavailable) Xilinx FPGA?
Question #4: Current supply chain issues are making many devices unavailable in the near-term, and I would like to standardize on a particular DMD. If a current application can live with the 3310's native 1368x768 image, can this (using the native resolution) be easily done on the 3310 chipset without the additional pixel shifting, preserving the possibility of later going to the full 1080P using the same DMD, controller pair and power manager, and adding the pixel shifting technique?
