AI Technical Summary
Technical Problem
LED displays experience uneven brightness between video and text areas due to different refresh rates, leading to poor user experience.
Method used
A display panel compensation method involving a refresh control signal to configure different regions with varying initial voltages and ground voltages, adjusting supply voltage levels to maintain consistent brightness across the panel.
Benefits of technology
The method ensures uniform brightness across the display panel by compensating for brightness differences caused by varying refresh rates, improving visual quality and reducing power consumption.

Abstract
A method for compensating a display panel includes: providing a refresh control signal to configure a first region and a second region of the display panel; and providing an initial signal to the display panel. The initial signal includes a first initial voltage for initializing the first region before a first data operation, and a second initial voltage for setting the second region without performing any data operation.
