Raspberry Pi Display 5 Inch HDMI Touch Screen can even power the entire display from a USB port. With the default 5″ 800 x 480 display and 50 mA back-light current, the current draw is 500 mA total.
You can reduce that to 370 mA by running the backlight at half-brightness (25 mA). With the backlight off, the decoder and display itself draw 250 mA. If you want more backlight control, there’s a PWM input, connect that to your microcontroller or other PWM output and you can continuously dim the backlight as desired. 5 inches, HDMI, LCD, Raspberry Pi, and TFT are available in Embedded Studio
In particular, we suggest it for use with single-board computers (or desktops/laptops!) with DVI/HDMI output like the Raspberry Pi or BeagleBone Black. You can power the driver over USB if your computer can supply 500mA on the USB port, and then feed it video via the HDMI port.
It’s a mini panel-mountable HDMI monitor with a built-in touchscreen! So small and simple, you can use this display with any computer that has HDMI output, and the shape makes it easy to attach to a case or rail. This backpack features the TFP401 for decoding video and includes the attached display so it’s plug-n-play.
The TFP401 is a beefy DVI/HDMI decoder from TI. It can take unencrypted video and pipe out the raw 24-bit color pixel data – HDCP is not supported! The 5″ display is 800×480 resolution, which is just enough to run most software, but still small enough that it can be used in portable or embedded projects without the bulk.
