The Rationale Behind TFT LCD Displays Superiority To CRT

By Alex Stein


In the earlier times, the monitor market was fully controlled by CRT displays, but during the current times TFT LCD displays have taken control of the markets. For this reason, the CRTs have currently diminished to mere freebies. The main cause of their preference difference is how the two models are. Some of the factors that have lead to TFTs being more preferred are stated below.

The initials CRT represent Cathode ray tube. It is mainly a large monitor screen with large features and it is usually very heavy. In addition, these systems are highly prone to damage when exposed to physical forces such as shock or vibration. They are also known as light tubes because they hit the phosphorous layer electron beam sequentially.

The articulate and strict safety and health regulations placed limits on how long one should sit on a computer because of the CRT monitor. These regulations were implemented in different workplaces. When using this monitor, you were exposing yourself to the electron beam drawing the picture hence limiting the time one could spend on a computer.

With technological advancements, the LCD monitors were introduced. LCD is the short form for liquid crystal display or thin film transistor in the case of TFT. They address individual spots, sub-pixels and pixels while being in a tight nutshell. This layer allows or blocks light to pass, by changing its crystal structure to either opaque or translucent.

The following features allow the TFT monitor to dominate the market over its predecessor. This monitor's LCD layer helps it controlling the light that goes through which greatly affects the color presentation, power consumption, picture quality and durability. The CRT monitor on the hand has a high power consumption, poor color presentation and limited durability. This is because of the cathode ray tube, which is an old technology.

LCD monitors are light and this makes them easy to transport and move around. They also save on usable space in the office or in a room due to its compactness. The cathode tube makes the monitor bulky and heavy therefore making it difficult to transport.

The new display version are capable of keeping pace with the ever changing market trends. The reason behind it being the presence of transistors that is changeable to improve performance. With the changes, the display is able to adapt to the multimedia applications that keep increasing.

With these new PC displays, there is a lot of demand and competition in the market, which tends to make them cheaper. This in turn makes people turn to using them because they are cheap and provide quality services. That is, the prices become achievable and reasonable for even the most casual PC user.

The final point is that TFT LCD displays are usually healthy to any user. Cathode ray tube monitors are usually harmful to human health, because they produce harmful light. The LCDs have a light control device known as liquid crystal display layer. What more is that they are usually resistant to both pressure and vibration hence making them more durable than their competitor is.
