Motorola

The Motorola MCVVQ111 is a driver-chip for this display, generating the timing and voltages our of a Composite-video-signal (RS170) and 2 power-supplies (2.5-5.5V and 11V). The RS170-eval-board from Tekgear uses a similar IC, the MCVVQ110 which runs off a single supply (but is no longer in production?).

• Justin has a layout as shown below:
• 2 PCBs were constructed based on this design. The first was a little flaky (just bad soldering) and encountered overheating problems which eventually damaged the IC. The second was constructed somewhat more robustly and works perfectly.

Kopin ASIC

Kopin sells an ASIC, that can drive the display. The Mototola-part is much better.
