Shortage of decent monochrome display panels
Posted: Fri Dec 06, 2019 1:34 pm
Hello everybody,
Wanted to talk about the situation we have in the industry.
With each year we have less and less cheap panels that can be directly driven by MCUs or being driven by a simple driver ICs that have connectivity options for MCUs.
The shortage is especially acute in mid-size panels, and panels in above of VGA resolution may well cost you more than true-color LCD panels with MIPI interface.
Pretty much the only option available in above xga resolution are e-paper panels, or very old stock speciality panels. Both cost a lot.
The few remaining options to connect a MCU with a higher end panel are things like custom FPGA bridges, or using a way more performant SoCs to do conversion. This makes little sense to use an IC more expensive and more powerful than the main MCU to just drive the panel.
I would like yo hear your opinions. How do you deal with that?
Espressif reps, what do you think about that?
