CRT Displays have been popular in the market for a very long time until recently when the TFT LCD Displays took over from them. This domination has reduced the value of CRT to the extent where they are being offered as freebies. The massive difference between these two display types is what brings about the dominance of former. TFT Displays are dominant because of the reasons 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.
Using a CRT monitor exposes the user to the electron beam that draws the picture. For this reason, strict, articulate and safety regulations were implemented at the place of work ton protect workers eyesight. This regulation stated the duration one is supposed to sit on a computer beyond which it becomes a health threat.
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.
Another great advantage is that these LCD monitors are compact and hence they help to minimize the space consumed in any office. The cathode ray tube monitor is normally very large and hence it consumes a lot of space. In addition, it is usually very heavy hence it is very difficult to move it from one place to another. Other modern monitors are usually very light and can be easily relocated.
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.
Market competition has made the PC displays cheaper for most people to afford. With the cost and quality services, more users are coming up including the most casual user. This means that even the low income earners can afford them.
TFT LCD displays do not emit dangerous light to the environment since it is controlled by a display layer with liquid crystal. The safety and health boards have given them a green light based on this fact. They are also more long lasting than the CRT displays due to their resistance to vibrations and pressure shock.
