Hi,
wow, thanks a lot for that quick help and the suggestions, Tomi :)
I hope ED makes the right decision and at least uses lower resolution screen.
Well, I ordered 5 samples of that screen, here is my current plan:
- Let Nikolaus create a few new display PCBs for that display where we
can optionally add the Solomon Tech chip
Yes, should not be difficult.
Maybe the easiest solution would be to make a modified variant of the simple EVM adapter first.
I remember the data sheet of the Solomon chip was attached to some recent mail but I don't remember the one of the display.
- Test both displays with TILER for rotation. Check cpu and battery
usage as well as overall usefulness (i.e. as mentioned FireFox ignores dpi and is unusable with default settings, I will test multiple standard programs). 3. Test the BOE display incl the Solomon Systech rotation chip and compare the differences of CPU usage.
Right now, I'm in favour of the BOE LCD, for various reasons:
- Leadtime is 20 days (LG has 12 weeks and didn't even keep them last
time) 2. BOE offers all needed datasheets without any issues 3. MOQ of the BOE one is 5 pcs, LG has 5000. 4. Price! The LG display is about 65 - 70 EUR. Applying the touchscreen does cost 10 EUR, I don't know he price of the touchscreen yet, but it will probably be around 2 - 4 EUR. So in total: about 80 - 85 EUR. The BOE screen is 55 EUR when ordering samples - with 1k it will probably be about 35 EUR. The touchscreen can most probably be applied by BOE directly and will cost a few EUR. (I'll get these details within a few days). 5. The LG display can go EOL anytime.
They likely will have a successor with slightly modified specs. But it is very unlikely that they will not have a Full HD panel. 5 inch is "the standard" for smartphones and LG mobile is trying to follow on the heels of Apple and Samsung.
The BOE display is currently being used in many chinese smartphone displays, so it'll not go EOL anytime soon.
So our source is more reliable, I can buy 1000 for about 40,000 EUR (instead needing to get 400,000 EUR to be able to buy 5k of the LGs) and we have a better support as well and our system will be faster and probably more useful (as we don't need to fix so many apps to be usable on that high resolution)
Yes, the commercial side is much better. Well, there is more competition for this resolution. On the other side the display is one of the key components/ features of the Pyra and a higher resolution would be more outstanding and unique, even if more expensive.
But in the end you must decide the whole package ("ahead-ness", complexity, risk, cost, etc.).
So I want to test that, but it seems to me the BOE is the better choice.
