4.3" 40-pin TFT Display - 480x272 with Touchscreen Product ID: 1591
Description
This 4.3" TFT screen has lots of pixels, 480x272 to be exact, an LED backlight and a resistive touchscreen overlay. Its great for when you need a lot of space for graphics or a user interface. These screen s are commonly seen in consumer electronics, such as miniature TVs, GPSs, handheld games car displays, etc. A 40-pin connector has 8 red, 8 green, and 8 blue parallel pins, for 24 -bit color capability .
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 suppor t 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 tha t can go as high as 24V instead of our other small displays that can run the backlight off of 5 V 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, b ut we don't have any support or tutorials for that purpose .
