AI Technical Summary

Technical Problem

In existing driving circuits, there is a parasitic capacitance between the switching circuit section that controls pixel brightness and color and the data voltage circuit section, which leads to a feedthrough effect, affecting the accuracy of the data voltage and thus affecting the display effect of the display panel.

Method used

In the driving circuit, by turning on the switching unit before the data voltage unit is turned off, the influence of the feedthrough effect on the displayed data voltage is avoided, and by turning on the switching unit during the data voltage unit's conduction period, the voltage fluctuation amplitude at the node of the switching unit is reduced, thus ensuring the accuracy of the displayed data voltage.

Benefits of technology

It effectively avoids the impact of feedthrough effect on the display data voltage, improves the accuracy and uniformity of the display, simplifies the modification process of the drive circuit, has strong applicability, and improves the overall display consistency of the display panel.
