The quarter-final between Ding and Trump was a match of high quality in terms of scoring, with seven of the nine frames containing a break of 70 or above.
Ding, the 2011 Masters champion, began in style with well-made contributions of 70 and 74 to take a 2-0 lead.
Left-hander Trump responded with a 75 to reduce the deficit but, when the two-time Masters winner missed an awkward red to the corner in frame four, Ding capitalised with a 72 clearance.
A 97 break brought Trump back within one frame at 3-2 and he knocked in a half-century following Ding’s error in frame six, after which the world number nine failed to pot another ball in the match.
The 2019 world champion was dominant from then on, with superb breaks of 125, 62 and 75 completing victory.
Trump told BBC Two: “I didn’t feel like I’d done a lot wrong [to be 3-1 behind].
“I was disappointed to lose the last frame before the interval, but it’s very fine margins at this level. Sometimes you finish perfectly and clear up, sometimes you miss and your opponent clears up.”
