Hi,all

   My device is imx53 + DA9053 +wec7.0, TS controller is DA9053。There is a phenomenon when we choose 5.6-inch resistive screen + display : touch screen  close with the display, long press the touch screen, there will be Drift of the phenomenon ; the touch screen and display screen separated by a distance, will not have this phenomenon.   Also selected 6.5-inch and 3.5-inch screen did not appear。(Note: the replacement of other manufacturers touch screen, troubleshooting screen quality problems)

    Touch screen manufacturers FAE suspected to be due to touch screen and display signal interference caused this problem, modify the touch screen controller reg to adjust the touch screen configuration (measurement confirmation, the resistance of TS is not the same, 6.5-inch screen resistance were 525/406, There are drift problems 5.6 inch screen resistance were 533/366).

    Excuse me, is this question really caused by this reason? If yes, how to modify the driver (wince7.0), matching resistance? If not, what is the reason for that?
