AI Technical Summary

Technical Problem

In the display panel, due to a voltage difference between the driving voltage corresponding to the touch signal and the driving voltage corresponding to the vacant signal, the parasitic capacitor is charged and discharged during the transmission of the display signal by the display circuit, resulting in uneven display problems.

Method used

By controlling the first driving voltage in the off state when the touch signal circuit is in the driving state, and driving the touch signal circuit through the second driving voltage, or driving the touch voltage through the second driving voltage when the touch signal circuit is in the driving state, the touch voltage is driven by the second driving voltage when the touch signal circuit is in the driving state. Control signals and vacant circuits to avoid parasitic capacitance discharge caused by voltage differences.

Benefits of technology

It effectively avoids the impact of parasitic capacitors on the display of the display panel after the touch state is completed, and improves the display effect and user experience of the display panel.
