24-RGB LTDC ESD Protection

[nman]

Hi. When utilizing a 24-RGB interface, should each individual signal line be equipped with ESD protection? This would demand a small army of TVS diodes/arrays, which is fine, just want to make sure that this is an industry-standard approach.

Thanks.

Dear @nman ,

Welcome in STCommunity .  Indeed this will depend on your application : industrial /consumer products and the level of ESD protection to reach on top of our GPIOs . You can see our reference demonstration boards and connected LCDs :
