LED Video Wall vs. ProjectorPosted on Friday, January 29, 2016
Plenty of devices use light emitting diode technology to serve their objectives. Among them is LED billboard, commonly used for advertising in the Philippines. Another example of devices that use the LED technology is video walls. In corporate meetings or events, LED video walls can be useful in displaying high resolution infographics to a wide audience. Its function can be compared to that of a projector.
A projector is a small device that is used to project computer generated images onto a flat surface – like a wall or white board, for instance. Usually, you can find this in universities, professors use them during discussions or lectures. Some of you are probably wondering: if LED video walls and projectors have basically the same function, which is better? If you are torn between buying a projector or a video wall for office use, check the comparison below.
Comparing the brightness of LED video walls and projectors can be tricky. This is mostly because their lights are measured differently. The LED light is measured in NIT (measurement of direct light) while a projector’s light is measured in lux (measurement of reflected light).To help you understand, 1 NIT is equal to 3.426 lux. This means that a lot of LUX is needed to achieve the brightness that LED video walls provide.
In any case, a projector’s brightness fades faster than an LED video wall’s. In a year or so, its brightness would have gone down to 70% of its original illumination. Meanwhile, you can expect that an LED video wall’s brightness will remain in top condition even after a year. This is because LED video walls use only at least 20% to 30% of its brightness capability.
Both video walls and projectors can be used to display images, text, or videos. The question is, between the two, who can provide a better image quality? Almost every display device nowadays is capable of exhibiting high definition content. While this is true for both LED video walls and projectors, the latter is still limited with regards to this aspect.
Once the bulb of your projector starts to become obsolete, the quality of the images it projects starts to deteriorate as well. In comparison, an LED video wall can continually display high quality images, text, and videos without any worries.
When reviewing the costs of two devices, don’t just rely on the initial cost. If you want to know which product is a much better investment in terms of budget, you have to look ahead and factor in the costs that you might acquire for either of those gadgets in the future. Before anything else though, start with the initial cost. Upfront, an LED video wall will probably cost you more than a projector. This means that at first look, a projector might be the cheaper option between the two.
Now, start factoring in the added expenses, beginning with maintenance. As discussed above, the brightness of a projector starts to wear down around its first year. If you want to get it back to 100%, you’ll have to replace the bulb every year. In addition to that, you’ll probably have to replace the projector’s light engine after year 3; and then again on the sixth year.
On the other hand, you don’t have to replace any bulb or light engine when it comes to LED video walls. Instead, you have to replace its modules. Don’t worry though because this is not bound to happen until maybe year 4. The number of modules that you have to replace will increase by years 7 and 10. Despite this fact, it’s still cheaper to replace modules than bulbs and light engines.
The energy consumption will also fall under additional expenses. Between the two, you’ll probably save more money with video walls, in terms of this aspect. LED video walls only need half of the power that projectors need to be able to function. Lastly, don’t forget that the average life span of an LED video wall is 12 years. In comparison, a projector’s average life span is around 5 years.
Between projectors and LED video walls, the latter is a better option. LED video walls don’t just provide superior brightness and image quality, it’s also cost efficient. With its many advantageous features such as energy efficiency, long life span, and durability, you’ll surely find LED video walls the superior choice between the two.
