AI Technical Summary
In Long-H mode, the threshold voltage of the output transistors of the touch display panel drifts due to the fixed position of the stop hole, resulting in inconsistent driving characteristics between the stop hole rows and the non-stop hole rows, which can easily lead to H-line problems.
By determining the pit stop position of each frame within the dynamic pit stop cycle, offsetting it by the target number of lines, and generating timing control signals for display and touch control, the pit stop position corresponding to each frame is ensured to cycle within a larger area, balancing the additional bias voltage accumulation count borne by the output transistor.
It effectively improves the H-line problem in Long-H mode, enhances the driving capability consistency of output transistors, and avoids horizontal stripe defects on the panel.
