I'm search for compatible 4-6" touchscreens with the Raspberry Pi (Zero W, but I think it's the same for all of them) with capacitive digitizer. My questions are:

  1. Does DSI support the touch digitizer or I'll have to buy/connect it externally?
  2. What I have to look for in a datasheet to see if a screen is compatible? (for example is Nexus 5 screen/digitizer compatible?)

Just to be clear: I want to connect a screen DIRECTLY to the DSI. Not with a "daughter board" that breaks out HDMI.

If you have any recommendations for a (touch) screen please add them to the comments, but that's not the main question.


The Pi Zero W only has CSI for connecting to a camera module, but it hasn't a separate DSI for connecting a display. The DSI connector is only present on the A/Bs (and CM, if I'm not mistaken). The GPIO header only optionally carries DPI (used, for example, by the HyperPixel display).

  • so for a 4-6" high res capacitive touch screen I'm out of luck huh? – dzervas Aug 27 '17 at 18:11

    Yes, if you want to use a Pi Zero W. – TheDiveO Aug 27 '17 at 18:37

Is use of DSI a must ?

As @TheDiveO says, the Pi Zero hasn't a separate DSI for connecting a display.

BUT, there are 7" touch screens with HDMI input available on Amazon US for $77 (that's the first one I found, but WaveShare have a great rep for displays).

The same display costs GBP £74 on Amazon UK This is a rip-off, as usual for the UK, using a 1:1 exchange rate. However, there are good alternatives for £45 (non-touch ) and for £53 (touch screen).

You can find similar, cheaper on Ali Express.

I would recommend buying a mini to standard HDMI cable, rather than using a converter with a standard cable.
