Refresh Rate – It is the number of times the Display updates its content (picture/frame) per second. It is measured in Hertz (Hz).
Touch Sampling Rate / Touch Response Rate – It is the number of times the screen registers, scans, or detects input in a second. It is also measured in Hertz (Hz). You can find out the exact time the screen looks for new input by dividing it by 1 sec (1000 ms). For example, if the touch response rate is 60Hz, then 1000/60 = 16.67. This means the screen looks for new input every 16.67 ms. You can refer to the table below for a higher-touch sampling rate. Also, you can know about Touch Sampling Rate in our detailed article here.
