This version does not have touchscreen attached It’s exactly the same TFT display as PID 1596 but without the resistive touch panel so it is a little less expensive.
This is a «raw pixel-dot-clock» display and does not have an SPI/parallel type controller or any kind of RAM. The display is supposed to be constantly refreshed, at 60Hz, with a pixel clock, V sync, H sync, etc. There are some high end processors such as that used in the BeagleBone that can natively support such RGB TTL displays. However, it is extremely rare for a small microcontroller to support it, as you need dedicated hardware or a very fast processor such as an FPGA. Not only that, but the backlight requires a constant-current mode boost converter that can go as high as 24V instead of our other small displays that can run the backlight off of 5V
For that reason, we are carrying it only as a companion to the Adafruit RA8875 driver board in the store, which is a chip that can handle the huge video RAM and timing requirements, all in the background. That’s the best way to interface this display to just about any microcontroller (including Arduino & friends) If you are an advanced electronics enthusiast you can try wiring this directly to your processor, but it we don’t have any support or tutorials for that purpose.
- Dimensions with Screen Backing: 120mm x 75mm / 4.7″ x 3.0″
- Screen Dimensions: 110mm x 67mm / 4.3″ x 2.6″
- Weight: 61g
- There is no resistive touch screen so pins 37-40 are NC.
