一种提升OLED显示面板显示效果的补偿方法
By introducing a detection compensation module into the OLED display panel, the data voltage or brightness gain value is dynamically adjusted, which solves the problem of uneven brightness caused by the TFT hysteresis effect and improves the display effect of the OLED display panel, especially the brightness uniformity at the edge of brightness abrupt changes in static display images such as white background with black text.

AI Technical Summary
When switching between high and low grayscale, OLED display panels experience uneven brightness and ghosting due to the TFT hysteresis effect, resulting in insufficient response time. This is especially noticeable at the edges of sudden brightness changes in static displays such as white backgrounds with black text.
Introducing a detection compensation module into the OLED display panel, by calculating the number of compensation rows and detecting the area to be compensated, dynamically adjusts the data voltage or brightness gain value to eliminate brightness deviation at the edge of brightness abrupt changes and ensure consistent display effect.
It improves the display effect of OLED display panels, eliminates brightness gradation mura at the edges of sudden brightness changes in static display images such as white background with black text, and improves display uniformity.
