STM32F429 / 439 LTDC TFT-LCD PCB design guidelines and TFT selection

Question asked by dimopoulos.stavros on Sep 26, 2014
I want to design a PCB that uses the embedded LCD-TFT controller of the STM32F4x9.
Are there any guidelines available for the PCB design for the traces from the MCU to the LCD-TFT connector?
Is a specific trace impedance required ?


Do the TFT displays have strong electromagnetic emissions? Is there any compliance certification that I should look for then I search the market for a display for my project?
