Provided are a display substrate and a preparation method thereof, and a display apparatus. The display substrate includes a display region and at least one hole region located in the display region, the hole region includes a function hole and a partition region surrounding the function hole, the partition region is provided with at least one partition dam surrounding the function hole; the partition dam includes a first partition layer disposed on a base substrate and a second partition layer disposed on a side of the first partition layer away from the base substrate, at least one partition layer includes a second sub-layer and a third sub-layer disposed on a side of the second sub-layer away from the base substrate, the third sub-layer has a protrusion with respect to a sidewall of the second sub-layer, and the protrusion and the sidewall of the second sub-layer form an inwardly recessed structure.

Display substrate and preparation method thereof, and display apparatus each including partition region provides with at least one partition dam surrounding function hole

First, image data are converted to first tone data for primary color inks, and then converted to second tone data for primary color and black inks, by under color elimination. The combinations of the above tone data for primary color and black inks, in which bronzing occurs when images are printed on the printing medium, are recorded beforehand as the conditions under which bronzing occurs. The determination of whether or not the conditions under which bronzing occurs are present in the above second tone data is made according to these conditions under which bronzing occurs. If bronzing will occur, a part of the under color elimination is converted to primary color inks. In this way, it becomes possible to print images in which bronzing does not occur. This process may also be executed by using color conversion tables.
