Hi,
okay... I'm now getting more and more LCDs which I could buy. This one would be 20,75 EUR (which is an awesome price).
The specs are similar to the BOE one, typ response rate is 25ms. The connector is a bit weird, but it could be we can get this changed.
I've attached the datasheet for both the display and the driver IC.
Nikolaus: Can we build the next display board as multi-LCD PCB, so adding connectors for these two displays (BOE and Success)?
Hm. That is a little difficult. Each panel needs a slightly different power supply. MIPI should be the same for all.
But I will check if these two are reasonably similar.
Yes, we are lucky. They are almost the same and the backlight has the same spec (2x6x3.0V @ 20mA)..
Both are a little better that they just needs a 1.8V for I/O and ~3.3V for supply. No special +/-5V converter like the LG panel (where I still wonder why they did require us to have it externally where we know that the Renesas chip could do it autonomously).
Both even use the same Hirose connector series FH26 - but the BOE uses a 27 pin variant FH26-27S-03SHW and the Spectrum a 31 pin variant FH26-31S-0.3SHW(05).
So it look as as if I can add both connectors for testing purposes :)
Then I'd order samples as well - and we could test and compare both together with the Solomon Chip and select the best one :)
