DLPC230-Q1: The dynamic range of R、G、B lights is inconsistent within one frame in our PGU

Hello Li,

I have notified the party who handles this chipset about your inquiry.  There is a lot to understand here.  Please allow a day or two for a response.

Hello - 

This allocation is intentional. Typically more time is allocated to green since it makes up more of the white light, resulting in a brighter projector.

However, this setting (RGB Duty Cycle) can be adjusted in the Composer project.

Hello,Ross! Thanks for your answer!

Truely, the ratio of drive time assigned to R, G, and B by LED_SEL drive signal is 30:45:25  (The ratio of the cumulative on-time of one frame)。

However, the dynamic range of a single lamp bead is the ratio between the total drives to the minimum drive time，as shown below:

As we asked at the beginning, we thought the dynamic range of the three lights should be consistent. But apparently not, we don't know why。Thank you!
