LED Screens have gotten a lot of media coverage over the past several months. They have been used to replace traditional CRTs for high-resolution digital signs, such as in traffic directions, weather forecasts, and in cinema theaters. The main problem with LEDs, however, is their rather limited range of applications, making them unsuitable for outdoor use. They are also quite expensive when compared with competing technologies like LCD and plasma displays.
The first problem is that LED displays are not a true ‘flat’ display as they must be ‘flatter’ than a cathode ray tube screen. A pixel is essentially a dot on a screen, but because of the electron orbitals, there are a finite number of such dots per pixel. This means that there are only so many pixels per square inch, or frequency of display, meaning that if you have a larger screen, then the number of LED pixels per frame is correspondingly lower. This is referred to as the’pixel pitch’. The problem with using LED displays for outdoor applications is that they cannot be used as flat panels with any consistency.
Secondly, the cost of LED screens is still fairly high relative to LCD and plasma displays. In fact, the difference between the highest and lowest priced LCD monitors is roughly four times as large as the gap between normal lcd and led screens. Add to that the price of shipping and installation and you still end up with very large gaps in pricing between the top brands. The result is that while companies like Dell, HP, Sony, and Apple are able to produce LED-based televisions at prices competitive with LCDs, consumers are largely limited to buying from companies like LG, Samsung, and Acer – all of whom outsell the competition substantially.
The final major disadvantage of using LED screens is their power consumption. LED diodes consume a great deal of power, which makes them unsuitable for use in applications where the power consumption needs to stay at a stable level. Even in their high power consumption state, lcd and led screens are still more expensive than ordinary flat panel displays. They also have a shorter life span, making it more expensive to replace the display panel in the future.
So, overall, there are many advantages of using transparent LED technology over normal LCD or plasma televisions. One of the primary reasons is because these devices are able to display full color imagery at full resolution, something that normal LCD displays cannot achieve. Additionally, LED screens do not have to have an active backlighting system like most lcd and plasmas do, which also reduces power consumption. Finally, the fact that these devices have a very short lifetime and consume a great deal of power make them unsuitable for outdoor applications.
The decision between lcd or transparent led screens will likely come down to your overall viewing habits, the amount of power you need to operate the unit, and the types of content you will be displaying on the unit. If you are someone who rarely uses computer screens and spend most of your time viewing media, then the obvious benefit of one of these devices would be a substantial increase in the amount of information you can view. However, if you are somebody who works frequently on a computer screen and would like to add extra colours to the screen, then purchasing one of these devices might not be worth the purchase. As with most things in life, it is often a matter of prioritizing what is important to you and how much you are willing to spend.
