Raspberry Pi is a single board compute module, developed in the UK by Raspberry Pi Foundation for promoting teaching of computer science in school curriculum. When Raspberry Pi evolved it didn’t had a display unit attached to it. But, then Raspberry Pi Foundation and other display unit makers came to rescue of people and helped them enjoy their learning with this device. Encouragingly, Raspberry Pi can be connected to VGA, RCA and HDMI display units. Raspberry Pi TFT display unit is among the highly preferred display module for Raspberry Pi.

Now, that you have a Raspberry Pi display unit in market, your communication with your compute module will be more interactive. Apart from Raspberry Pi TFT version of Raspberry Pi Foundation, you can find many other brand display units for your computing machine. But, before you purchase a display screen for your device, you must know its key features, which will help you to choose best one available in market.

Features to watch out for while purchasing Raspberry Pi display unit

As Raspberry Pi is very fondly called as credit-sized compute module, one wouldn’t wonder ...
... to know that display units that are mounted on this Raspbian based compute module are just as big as some of mobile display units. Raspbian is the Operating System used in Raspberry Pi, which is said to have “Compute Module Aware” and its latest is recently launched in the market. Key features that you should look forward to while purchasing TFT display unit for Raspberry Pi is,

Resolution

This feature is important as it only decides what quality of videos and images your display unit will produce. Generally, standard 320 x 240 resolution display is recommended for Raspberry Pi display, which supports 65k colors in its display.

Touch screen

Most mobile and tabs are touch screen enabled, then how could this miniature computing model have stayed behind. Though, in market you will find display versions those are not touch screen enabled. You should look for Raspberry Pi TFT display screen that is touch screen enabled.

Push Buttons and its status update

Raspberry Pi display comes with push buttons on its surface, which can be used to assign function like printing. You can look for a 5 push button display screen as at this point of time, as it is the maximum push button display units that are available in the market. Display is connected through GPIO and SPI pins only, that powers these push buttons. You don’t have to plug any extra or separate pins to activate push button functionalities. You can also check status updates of each push button, which is read over SPI.

Mounting holes

As said earlier, TFT displays are mounted on Raspberry Pi separately, you should look for a display that is made for your Raspberry Pi version. Misplaced mounting holes will not allow mounting of your display on Raspberry Pi machine. Check that standard M3 size screw/blots are packed with your display.

There are various other controllers attached to Raspberry Pi device, you must check that your preferred display supports these controllers.
