Or you can just check out the connections for the pins of the Raspberry Pi touchscreen LCD display module as shown below. In case you need to utilize other pins on your Raspberry Pi for the project, you can then use the Raspberry Pi's GPIO-to-breadboard connectors (male-to-female) like these. This will have to be the easiest step since you just need to take the LCD module and plug it in to your Raspberry Pi's GPIO pins as shown in the picture above. You can build head-mounted displays (like the SmartCap), a portable kiosk, or just add it to any of your existing projects where you need an LCD display with a touch interface. You can do a lot of things with these displays. As far as I could tell after research, it is the cheapest and the simplest LCD with a touch interface that can be added to Raspberry Pi projects. The screen I chose was the Waveshare SpotPear 3.2-inch LCD display with resistive touchscreen.

This TFT LCD display also has a resistive touchscreen and a stylus. In this Raspberry Pi touchscreen LCD tutorial, I will show you how to interface an extremely simple and cheap 3.2-inch LCD display. You could even make your own customized smartphone! However, most displays are not used because they are expensive and complicated to interface with the Raspberry Pi. You can build on a prolific number of applications using portable TFT LCD displays. Having a nice display always boosts the overall portability of your project. Touchscreen displays are one of the coolest things you can add to a Raspberry Pi.
