For many customers, video wall installations that include hardware and services are an ideal fit.
Front and rear service access
For easier installation and low-cost maintenance, video wall panels should have front and rear access.
Cost
LCD panels are less expensive than LED panels; however, the gap is narrowing. Pixel pitch is the primary contributor to the higher cost of LED displays; therefore, it is important to work with the equipment supplier to ensure the installation’s pixel pitch matches the client’s budget, image quality expectations, and content type.
Long-life
LED panels have lengthy longevity ratings. For example, models rated at 80,000 hours of use will provide more than 13 years of service. When a client chooses a video wall panel, it is important to ensure the display can be colour calibrated. The main reason for this is usually due to repairs when new LED panels are installed to replace older units. Having the ability to calibrate each display to closely match other panels can help avoid/eliminate square sections of the video wall being brighter or darker than others. Ultimately, calibration will make the video wall look like new and enable the content to look its best. It can also prove to be essential in the later years of the LED’s lifespan.
Turnkey
For many customers, choosing a video wall installation that is a complete, end-to-end solution that includes hardware and services will be an ideal fit.
The big picture
Thanks to recent advances in dvLED technologies, customers considering an indoor video wall installation now have options beyond the traditional choice of LCD displays. To steer clients in the right direction, it is important to decide whether the use of LCD or dvLED panels is the best choice for the project at hand. This decision depends on many factors; however, by matching the client’s needs with the benefits of the different technologies available, a cost-effective, long-term signage solution can be discovered.
