Abstract: Disclosed are a method for driving a silicon-based driving back plate and a display apparatus. The method includes: acquiring a watch position of a user on the silicon-based driving back plate within one frame time; determining a watch region of the user on the silicon-based driving back plate according to the watch position; and controlling a sum of an analog modulation bit for analog scanning charging and a digital modulation bit for digital scanning charging performed on each row of pixels in the watch region to be greater than a sum of an analog modulation bit for analog scanning charging and a digital modulation bit for digital scanning charging performed on each row of pixels in a non-watch region.

Abstract: A display panel includes a base substrate and a plurality of sub-pixel groups. The plurality of sub-pixel groups includes a first sub-pixel group and a second sub-pixel group. The first sub-pixel group includes two adjacent sub-pixels with a first interval therebetween, and the second sub-pixel group includes two adjacent sub-pixels with a second interval therebetween. The first interval is different from the second interval.
