I want to build a portable gaming console with the Raspberry Pi 3. The power source will be a LiPo battery.
Now I've been looking at some display on Digi-Key and I'm not really sure what to look for.
First, what type of connector? HDMI or parallel?
Second, the power supply of the display. For example on one display on Digi-Key it says this.
TFT Supply Voltage
min. 3.0 V
typ. 3.3 V
max. 3.6 V
Backlight Supply Voltage
min. 17.4 V
typ. 19.2 V
max. 19.8 V
And then there is this note: The LED of the backlight is driven by current drain; drive voltage is for reference only. Drive voltage must be selected to ensure backlight current drain is below MAX level stated.
I don't really understand what this means. My first guess was that the display requires a separate power supply with 17.4 -19.8 V which wouldn't really make much sense for such a small display? And then I read the above note and now I'm totally lost.

Looks like another Waveshare clone.rpiMike wrote: ↑Mon Nov 20, 2017 2:47 pmhttps://www.amazon.co.uk/Elecrow-Monito ... y+pi&psc=1
5 Volt power - same as Pi, mounts directly onto Pi, hdmi so no drivers for the display, also touch screen (although not the most accurate in my experience)
Yup, and for my fellow American Raspberry Pi users, this looks like yet another clone on Amazon USA for much less.
