    China Mobile Touch Screen repair(with pictures)


    Touch Screen IC 4182A and MT6301 same. See X- X+ Y+ Y- reference my picture jumper.


    Touch Screen use of 4-wire resistance screen* four lines are: X1* X2* Y1* Y2

    X1* X2 in the horizontal direction for a change in the resistance* Y1* Y2 for the longitudinal resistivity.

    How do you know which line is a two x1 x2 y1 y2? Touch panel along the four lines above are facing their own look at the screen from top to bottom in the line is about on both sides of the x1 x2 is y1 y2. Established phone touch screens measuring four points of the voltage. Two 2.7V and two 0v . two voltage are measured after boot. 2.7 v is y. X is not the voltage.

    After corresponding with xy can generally be connected. If the touch panel screen and click position opposite or reverse. Swap contrast x-y reversed.
