Hello,
i have question about your DT028ATFT and DT028BTFT display. I ask about non touchpanel displays versions. Is there any migration note between those two display? If not what's the difference between those displays?
Where am I?

Thanks for your patience. These displays are very similar and use different IC's (ILI9340 vs ILI9341). There are also differences in backlight module construction. More details below:

SPI InteracesSee ILI9341 datasheet sections 7.1.8-7.1.10, 7.6.1 and 19.3.3See ILI9341 datasheet sections 7.1.8-7.1.10, 7.6.2 and 19.3.4Thanks for your response. In accordance with information form website of that displays they both working with ILI9341.

I ask question because after change DT028ATFT to DT028BTFT in one of ours device we observe problem with noise. Everything was display properly but with additional noise on DT028BTFT. After increasing clock frequency noise on DT028BTFT was reduce and both display work properly. Displays in our devices are connected with FT800 engine.
Yes, there can be minor differences in performance between modules even when using the same IC.
