TFT which is short for thin-film transistors is a form of LCD flat panel display screen and it has different and every pixel controlled from a total of 1-4 transistors. This TFT technology is able to provide the very best of resolutions for different flat-panel techniques and it is safe to say that it is also quite expensive as well. TFT screens are usually known as active matrix LCDs.
This device is a combination that includes different overlay on touch technology present on your screen. Not only is it able to display content, but it can also act as an m interface device to whoever makes use of it. In this technology, TFT makes up more with the organic light-emitting diode screen which is known as the only worthy competitor.
TFT which is also called TFT screens with Arduino is very active forms of matrix LCD displays which can produce millions of high contrasts and in very clear and brighter color pixels too. TFTs place in HDTV sets, laptop monitors, computer monitors, tablets, smartphones, and personal media players and so on. TFT tech operates by brightness control in green, red and blue subpixels thriving the use of transistors for every pixel present on the screen. It is important to know that the pixels themselves do not produce any light but the screen makes use of backlight illumination. Not only does the TFT family LCD, include LEDs as well which are a form of LCD screens but with LED being the backlight.
The TFT LCD screen with Arduino is a backlit screen that has a micro SD card slot present at the back. With it, you can draw texts, shapes, imager and so much more to the screen of your TFT library.
The screen also shows up to 16-bit colors where the red and the blue possesses 5-bits of resolution respectively and thee are 32 levels of both. The green possesses 6-bits of resolution at 64 levels too. In order to remain consistent with a lot of other applications, the library has to deal with colors in 8-bit values for red, blue and green channels and does the scaling of colors appropriately.
Both the hardware and the software SPI interface are impressive as well. The screen should be configured in two different ways. One with the use of the Arduino hardware SPI interface while the other is to manually declare all pins. You should also know that it is no different in their functionality of screens in both methods but the use of the hardware SPI is better and faster when drawing. It is also important to note that if you plan on using the SD card on the TFT module, you require a hardware SPI.
There are a number of tutorials on how to set this up on the internet such as YouTube and articles and blogs to guide you in installing this technology. So why not give it a try today and control your TFT LCD with Arduino today.
