TFT Display, Its Kinds, Advantages and Disadvantages

The main objective of the display is to produce visual information. This information is visualized with the help of different technologies used in making monitors. There are many kinds of displays that are being used in various electronics devices across the world. It is also an observed fact that the wider and clearer displays increase the productivity of the person as well as business. With every passing day, the display technology is revolutionizing. The more compact display monitors with ultra high definition resolutions are becoming common. TFT Display is also a very common display which is being used in many display devices.  (TY for best 24 inch monitor article)

TFT Display

A thin-film-transistor liquid-crystal display (TFT LCD) is a variant of a liquid-crystal display (LCD) that uses thin-film transistor (TFT) technology to improve image qualities such as addressability and contrast. A TFT LCD is an active-matrix LCD, in contrast to passive-matrix LCDs or simple, direct-driven LCDs with a few segments. Wikipedia

Thin Film Transistor displays are the most common displays that are being used in LCD monitors. This kind of display first appeared in the laptops. Due to its efficient energy consumption, this has become very common. Nowadays, this display is being used in smartphones, televisions, LCD’s and many other devices. There are two kinds of TFT display. These are:

1. Twisted Nematic
2. The Super TFT
3. Multi Domain Vertical Alignment

Twisted Nematic

These TFT displays are the cheapest of all with only 6-8 bit color technology. These have a very little contrast ratio and angle. The maximum viewing angle of these displays is about 90 degree and the contrast ratio is 1000:1.

Multi Domain Vertical Alignment

These are the medium ranged TFT displays. These have wide viewing angles both horizontally and vertically. This is why these displays are also used on some mobile phones. The contrast ratio in these displays is 6000:1 which is a lot better than TN displays.

Super TFT

Super TFT displays are also called IPS displays which are commonly being used by many smartphone manufacturers. This kind of TFT display has a wide viewing angle with very high contrast ratio. Usually, the viewing angle of these displays is 180 degree and the contrast ratio is very great. These are the displays that are being used as rivals of Amoled displays.
Advantages
TFT displays have a lot of advantages and, therefore, are being used widely. Following are some of these advantages.

1-Energy Efficient
The very first advantage of TFT displays is that these are a lot efficient in energy consumption. Therefore, these are widely used in laptops and mobile phones.
2-Compactness
TFT displays are also famous for their compactness. These are much less in weight than CRT displays and are easily portable.
3-Better Colors and Contrast

TFT displays are also useful due to their vivid colors and good contrast ratios. This increased contrast ratio makes them fit for use in mobile phones.
Disadvantages
Along with many advantages, the TFT screens have many disadvantages also. These disadvantages are
1-Viewing Angles
Although TFT display has a wider viewing angle, yet the display does not look good when seen from some awkward angle. LED displays result in more perfect angles because of diodes accumulating at the edges.
2-Accuracy of Colors
TFT displays are also not much liked because these do not give perfect colors under certain conditions.
