Last week we got in touch with nearly 20 display suppliers from China listed on Alibaba. A few of them could offer us our display panel bound with a capacitive touch digitizer. If we order 100 pcs shortly, they are going to cost us around $35 each. We will get five samples in a few weeks. Those are going to be complete modules, with optically clear adhesive bound. No need to buy touch sensors separately anymore. We are also getting an HDMI-MIPI board that we can use to test the displays initially and as a reference, if something doesn't work right.

This looks like a promising endeavor. I've been searching for a display subsystem based on the CM4. Hoping to see this come to fruition.
