Hi,Doug, Thank you very much for your suggestion. It seems that this
cannot be changed on the hardware(already discussed with vendor, TDDI's IC
design is this) we really want the touchscreen to power on and off
together with the panel, where the panel is in charge and the touchscreen
always powers on after the panel and powers off before the panel.=====>As
shown in T16 in the datasheet, the current TDDI IC not only depends on the
power supply (the 1.8V power supply uses the same power supply for the
touch driver and the panel driver)， also depends on the RST state of the
panel. Only when the RST state is high touch HID can ready.
