The driver’s built‑in frame‑difference detector compares the current frame to the previous one; if the accumulated difference exceeds this threshold, it triggers a switch to the high‑frequency mode. | Sets sensitivity for automatic mode change. | | DSS_TIMER | 0x3C | 7:0 – Minimum time (in 10 ms units) the driver must stay in the low‑frequency mode before it can switch again. Prevents “chattering” when the display constantly toggles between static and dynamic content. | Controls hysteresis. | Whether you are a hardware engineer searching for
In the world of embedded electronics and display technology, having access to precise technical documentation is the difference between a successful prototype and a costly failure.
