AI Technical Summary
Technical Problem
Increasing the refresh rate of an LCD monitor shortens the pixel charging time, leading to voltage instability and image retention issues.
Method used
The subpixels of the liquid crystal display are driven by positive and negative driving signals respectively. The voltage conversion rate of the positive driving signal is greater than that of the negative driving signal. By adjusting the rise time, fall time and voltage difference of the driving signals, the charging efficiency of the pixel capacitor is kept consistent under the positive and negative driving signals.
Benefits of technology
It improves the image retention problem of LCD monitors at high refresh rates, ensuring the stability and consistency of display effects.
