Hi,
as we don't know yet if our current display will ever be working with proper speed rotating it with TILER, I've searched for some solutions.
Solomon Systech offers a MIPI bridge chip that can do stuff like rotation, scaling, color corrections, power saving, etc. That would be rotating without using the main system, so without any loss.
I've contacted them (find the datasheet of the chip attached). The chip has a pin connection for the OMAP5 for tear-free rotation.
The downside is: That chip can only do rotation up to 720x1280, so our display would not work.
BOE (huge LCD manufacturer) are sitting in the same building (in Germany), and they already sent me a datasheet for a 5" 720x1280 display (has 35ms response time though).
I've checked Panelook and apparently they also have a 5" 720x1280 display with 25ms response time.
So that display together with the Solomon Systech IC should solve the rotation issue - in case we can't get it to work with the LG display.
The display also needs a touchscreen, but as it's very similar to the LG one in size and the touchscreen will not have a frame but will glued to the LCD, it should work fine with a minor modification.
Let me know what you think about that :)
