Hello everyone .... I have a question - is it possible to control the selective activation of a led lamp, which is divided into, for example, 3 (middle, left, right parts), depending on the size of the printed object, control it so that only the LED lamp under the current part is turned on displayed ??

Not sure if your question is hardware level or software. Not sure if anybody providing hardware supporting this but it should not be difficult.
Nanodlp does not support it but if there is good use case and benefit to add it, we can support it.

This would be very beneficial for the large printers we design. The point is that the LED lamp should be controlled, for example, from the 3 pins of RaspberryPi, but in NanoDLP there would have to be an option to enable these pins based on the image. If there is a small object and the currently displayed mask is in the center, then only one control pin is turned on ... if the object enlarges and overlaps an additional area on the left or right side, then additional pins controlling the left and right LED lamps are turned on .

It would have to be done on the basis of raster image analysis ... If the white pixels are in the right area, the appropriate pin is turned on in e.g. raspberry PI

There are many benefits, e.g. the amount of radiation absorbed by the LCD panel is radically reduced, which will increase its lifetime and this solution will significantly reduce electricity consumption.

I agree with technical details. But consider it would not be useful for the majority of our end users, so right now it is not something could be justified to be added to mainstream nanodlp build.
