NOTE:
Floating
1. Make sure that the ITO resistance of COM0 ~ COM69 is equal, and so is it of SEG0 ~ SEG293.
These Limitations include the bottleneck of ITO layout.
2. To avoid the noise in different power system affect other power system, please separate different power
source on ITO layout.
3. The V0, XV0 and Vg power circuits have output pins, input pins and a sensor input. To avoid the power noise
affects the sensor of the power circuits. The trace should be separated by ITO and should be connected
together by FPC.
