Flexible Display Panel Symmetric Scanning Control

The patent implements dynamic scanning control by switching between two scanning modes: a first mode that scans from the first end portion to the second end portion, and a second mode that concurrently scans from both end portions toward a central portion. This dynamic adaptation allows the display panel to optimize its scanning behavior based on the desired display output, enabling symmetric image display when folded while maintaining simple single-direction scanning when unfolded.

The patent employs periodic action by implementing concurrent scanning from both end portions toward the central portion, where gate signals are alternately applied to corresponding gate lines in a synchronized manner. This periodic bidirectional scanning enables symmetric image display on both display areas simultaneously, with the scanning process proceeding in discrete steps from opposite ends toward the center.

The patent applies parameter changes by dynamically adjusting the gate signal pulse width based on the scanning mode. In the second mode, the pulse width is extended to accommodate the concurrent scanning from both end portions, while in the first mode, the pulse width returns to its original shorter duration. This conditional parameter adjustment enables symmetric display when needed while minimizing power consumption during normal operation.
