补偿方法、补偿电路和显示面板
By detecting the voltage difference of the data lines in the display panel in real time and outputting a compensation voltage during the blanking period, the leakage problem of the display panel is solved, achieving a synergistic effect of real-time compensation and zero overhead, improving brightness uniformity and reducing power consumption.

AI Technical Summary
In the design of high refresh rate, low power consumption and long life, leakage problems in pixel circuits of display panels can lead to uneven brightness, ghosting, decreased contrast and increased power consumption at low gray levels, especially causing obvious flickering and display abnormalities when driving at low frequency or in standby mode.
Through the coordinated operation of jump detection, threshold filtering, time quantization and blanking period compensation, the voltage difference of the data line is detected in real time and a compensation voltage is output during the vertical blanking period. The compensation is performed using the idle time period of the display driver to match the total leakage current and offset the leakage effect.
It improves the leakage current problem of the display panel, eliminates vertical crosstalk, reduces system power consumption, and achieves a synergistic effect of real-time compensation and zero overhead.
