AI Technical Summary
In existing AMOLED display panels, the challenge lies in generating detection trigger signals that are valid only for the row to be detected and whose timing is controllable in order to achieve high-precision external compensation.
Through an integrated circuit design that incorporates cross-frame precharging, selective triggering, and periodic reset, a detection trigger signal is generated. This includes a precharging module, an output module, a coupling module, and a reset module, ensuring that the signal has strict row selectivity and timing controllability within the standard gate drive architecture.
It achieves the generation of detection trigger signals that meet high-precision external compensation requirements, improves the display uniformity and brightness accuracy of AMOLED display panels, reduces the risk of malfunctions, and enhances the stability and anti-interference capabilities of the circuit.
