We have demonstrated in the previous work that the negative capacitor can effectively prevent the signal delay due to the parasitic capacitance in the current programmed OLED display. However, there were some problems in the real panel application. Therefore, we discussed the difference between the simulation and measurement results and proposed the methods to improve the negative capacitor performance. We also analyzed the stability of negative capacitor considering the parasitic resistance as well as the capacitance. Especially in the case of large display where the data line has large parasitic resistance, the negative capacitance value should be smaller than that of parasitic capacitance or the delay components should be inserted in negative capacitor for stability.
