Is LED digital display the best choice for you?

By BizLED Bureau

June 2, 2017: When it comes to choosing the ideal technology for a digital display, there are a number of factors that need to be taken into consideration. Demand for digital display is gaining momentum as its applications are increasing as well. These displays are now becoming popular in airport, sports arena or stadium, hotel or church, etc. But consumers should be aware of the different display technologies available in the market, and choose the best one as per their requirements. Here, we give a comprehensive approach to the existing digital display technologies that the consumers can choose from as per their requirements.

How to choose the right technology

It is essential that consumers should have a good idea about their specific needs, and at the same time, should know as to how they will gain from a particular technology. Here, it becomes necessary to consider some aspects that include ambient lighting conditions, budget, viewing distance, service, maintenance, indoor or outdoor and installation conditions.

Types of digital display technologies

In addition to the above mentioned aspects, consumers should pay attention to hardwares as well. It is vital to know whether an LED display will be better or a laser projector. Let us have a look at the different digital display technologies available in the market.

  • Laser: A laser projector will give about 20,000 hours of illumination and its color rendition and brightness stay steady all through the 20,000 hours of its entire life span. The entire cost of ownership all through the life of a laser projector prevails over a lamp-based projector. No lamp replacement is required for a laser projector, thus helping to save about $2,000 on a yearly basis.
  • LCD: One of the widespread display technology used is LCD. Here, edge versus direct backlighting is a chief consideration. While direct backlighting allows for smaller bezel with deeper depth, edge backlighting allows for larger bezel with thinner depth.
  • LED: All LEDs are distinguished by pixel pitch, which is the space between active pixels. With direct LED, there is emissive display technology, where the pixels produce lights. On the other hand, surface mount device or SMD LED has all three colors that include red, blue and green, and every pixel contains one SMD LED to create a full color display. Direct LED is characteristically used for indoors. DIP LED, or dual in-line package, is mainly used for outdoor installations.

Cost and size factors

Projectors provide the biggest image at the lowest cost. LCD provides the best pixel pitch for value. Even though LED is the most expensive of the lot, it provides limitless size. While, an LCD is limited to 98 inches, projector and LED are virtually limitless.

Viewing distance

As far as the viewing distance is concerned, what the display will be used for is extremely important. For instance, common viewing of a display such as large outdoor signage does not require as close of a viewing distance as compared to analytical viewing like CAD or CAM design work.

If the viewing distance is usually close, LCD is characteristically the ideal technology choice. When viewing from a longer distance free of resolution, projectors are the ideal technology to use. If there is unrestricted budget with regards to pixel pitch and viewing distance, LED is the ideal technology option.
