Is the response speed of LCD determined by the screen or the circuit?

It is mainly determined by the screen. It is difficult to improve the reaction time of liquid crystal, and it is easy to improve the speed of circuit. The disadvantage of LCD screen is "tailing", which manufacturers are studying, but this is determined by the nature of LCD screen. If it was a circuit problem, it would have been solved long ago. At present, there are 100HZ and 240HZ circuits, which have far exceeded 50 and 60HZ.
