Summary:	Global Demand Increasing Lead Times on ePaper Modules.
Description:	Due to increased global demand for AI chips, semiconductor fabricators are prioritizing AI chip production, which is sidelining display controller manufacturing. Crystalfontz is currently experiencing extended lead times of six months or more on products utilizing EPD display controllers. We request that POs are placed well in advance and forecasts are provided to us so that we plan accordingly. We are actively monitoring the situation and working to reduce the impact this may have on customers.
Reason:	Global semiconductor fabrication capacity constraints driven by AI chip demand have significantly reduced display controller production allocations across the industry. This is an industry-wide condition outside of Crystalfontz's control.
Impact:	Extended lead times of up to six months on affected EPD products Additional display controller types may be impacted as the situation evolves Product availability is subject to change
Availability:	Contact Crystalfontz Support for up-to-date information by emailing support@crystalfontz.com. Customers who can provide purchase forecasts or updated order projections are strongly encouraged to do so.
