HOW DOES A TFT MODULE WORK?
How does a TFT module operate? First, TFT stands for “Thin Film Transistor,” and it describes the control elements that actively control the pixels. Because of that, you hear a lot said about active matrix TFTs. How do the images get produced? It operates on a basic principle. You have the TFT LCD display, which has many pixels, and each pixel has the ability to reveal differing colors.
TFT displays also use a backlight that comprises fluorescent tubes to light a single pixel. When a small shutter gets opened, the light passes through. Of course, this technology is more detailed than what can fit in this article, but a simple explanation can give you an idea of how it works.
Just like LCD
Ever heard of an LCD monitor? LCD stands for a monitor technology based on liquid crystals that change in molecular structure as it is used. As a result of the liquid crystal changing their molecular structure, they allow for varying levels of light to pass through them, which is what gives the picture.
Every pixel on any screen is made up of three components: Red, green and blue. You might also sometimes see this stated as RGB, which means the same thing. Twisted Nematic TFTs are the most common device that employ this tech. Without voltage applied, the molecular structure will be in its natural state, but twisted by 90 degrees, which is why they call it a Twisted Nematic TFT. When the light gets emitted by the backlight, it passes through the structure. Once the voltage gets applied, it creates an electric field, and the voltage twists the liquid crystals so that they align vertically.
When it comes to the color filters of red, green and blue, each pixel will be made of the color cells. With a resolution of 1280×1024 pixels, you will have exactly 3840×1024 transistors. Pixels are decisive, and if you have a smaller spacing, it will give you the highest possible resolution, which means better picture quality. What happens if you have to switch to a lower resolution, which is often the case when playing video games? When that happens, the electronics scales the electronic size up to the maximum display panel size.

OLED vs LCD
An OLED display have the following advantages over an LCD display:
Improved image quality - better contrast, higher brightness, fuller viewing angle, a wider color range and much faster refresh rates.
Lower power consumption.
Simpler design that enables ultra-thin, flexible, foldable and transparent displays
Better durability - OLEDs are very durable and can operate in a broader temperature range
SOIC and TSSOP-packaged ICs can be great for finished products; they take up much less real estate and allow the end product to be more easily manageable from a size perspective. During the design phase, it's much more convenient to work with ICs without needing a magnifying glass. The SOIC/TSSOP-to-DIP adapter board has both footprints on either side of the board so that you can design with either package without needing to purchase another adapter board. It comes in 8, 16, and 28-pin footprints and can easily snap apart at your convenience.
If you look at the personal electronics market, you might assume that emissive displays such as organic LEDs (OLEDs) or micro LEDs are the best way to achieve the ideal automotive display. But numerous design and fabrication challenges – including lifetime, cost and peak brightness concerns – have delayed the implementation of OLED displays in automotive systems.
Outdoor LCD displays need also to cope with sunlight. Because of the sun’s brightness and its ability to make a standard screen unreadable, an outdoor LCD display is often several times brighter than an indoor LCD. LCD brightness is measured in nits (a unit of luminance) and most indoor screens have nit value of around 400; outdoor displays on the other-hand have a nit value exceeding 1200, giving them the power to cope with even the brightest of sunshine.
