AI Technical Summary

Technical Problem

In existing pixel circuits, the gate signal of the transistor in the first light-emitting control circuit requires a large voltage, resulting in a high risk of signal crosstalk.

Method used

The first light-emitting control circuit is set between the light-emitting element and the first voltage terminal. By setting the type of transistor, the source of the transistor is electrically connected to the DC voltage terminal, the gate voltage range of the transistor is narrowed, and the gate voltage is set to on-state and off-state around the voltage value of the voltage signal.

Benefits of technology

It reduces the risk of signal crosstalk, improves display quality, and reduces logic power consumption.
