Touch position drift.

Touch position drift.
Update Time:2012-06-06
Touch position drift. A. Conduct calibration.*1 Drift may occur if the surrounding environment changed. Ground the metal materials in the structure. Adjust sensitivity of the sensor on the driver screen. The gap between the sensor and LCD may not be enough. Make the gap greater than 0.7mm. Make sure that the tail is fixed. Do not touch the touchscreen upon starting (until the LED on the controller board lights up twice) because the controller board is checking the surrounding environment. Make sure that there is no scratch on the surrounding patterning. Scratches on patterning may cause drift. Make sure that the tail is not coming off or damaged. Touchscreen will not work at all in those cases.
