AI Technical Summary
Technical Problem
When existing foldable display panels switch from half-screen to full-screen display, there are differences in brightness and display effect between the two halves, resulting in an unsatisfactory display effect.
Method used
The display frame is divided into an upper half-frame and a lower half-frame. The pulse width of the drive signal is adjusted. By comparing the half-screen display duration with the standard duration, the display effect of the two half-screens is ensured to be consistent when displaying in full screen.
Benefits of technology
By adjusting the pulse width of the drive signal, the consistency of the display effect of the foldable display panel in different states was achieved, thus improving the overall performance.

Abstract
本申请实施例提供一种折叠显示面板的驱动方法及折叠显示面板。包括第一半屏和第二半屏，当对该折叠显示面板进行驱动时，将显示的每一帧划分为上半子帧和下半子帧，在半屏显示时，只有一个半屏正常显示，而当由半屏显示转换为全屏显示时，首先判断其在半屏显示时的时长，将其在半屏显示时的时长与标准时长进行比较，当半屏显示时的时长小于标准时长时，该驱动信号对应的第一脉冲宽度与第二脉冲宽度相同，当该半屏显示时的时长等于标准时长时，该第二脉冲宽度则调整为标准时长时对应的标准脉冲宽度。从而显示面板显示效果的一致性。
