Duntai IC debugging for interference source

In many cases, Duntai IC will be interfered, leading to TP automatic jumping point (such as ft6306, etc., which may come from LCD noise interference or motherboard electrostatic interference). In view of this phenomenon, the original IC factory will debug the software algorithm to cover the interference source to solve the problem. I want to know what kind of data this method is mainly used to debug, And what other adverse consequences will appear after the cover is finished. Please point out the confusion. Thank you!!#O5 e x) g% s - \, | 5 A.

Duntai IC debugging for interference source

I think what he adjusted should be the sensitivity.
it can be understood as follows: for example, if the base of a real screen is 0, and the change of finger touch is 50 ~ 100, you can set the screen to recognize the signal whose change is greater than 50, it will think that there is touch action, and if some noise is greater than 50, it will cause the screen to detect touch action, This is what you call the phenomenon of point adjustment.
at this time, the sensitivity of the adjustment screen is greater than 70.
at this time, if noise between 50 and 70 is detected, the screen still performs well, and there will be no disorderly point adjustment * g% @ + w9 K + ^ 9 {"?The bad result is that the touch of the screen is not sensitive, but I believe the IC factory should balance the noise and the real touch to the best, otherwise it will find out the interference source and improve the root cause of noise from the hardware.

thank you for sharing 3 N (y + e $s) J4 T.
generally speaking, it is to raise the threshold.

in this paper, we introduce the concept of sharing 3 N (y + e $s) J4 t
