LED placement within the module also affects image quality. Daktronics manufacturing positions LEDs so the light of one is not distorted or hidden behind another LED when viewed from a certain angles. Inexact placement of LEDs, called “shouldering,” can result in a display’s image looking more magenta from one angle and more cyan from another.

The selection of high-quality LEDs alone does not ensure a uniform, non-grainy display image. Manufacturers such as Daktronics go a step further by performing a proprietary “full-depth” factory calibration of each module during the manufacturing process. Daktronics calibrates modules in a specially designed chamber to ensure the consistency of every LED.

Finally, ask your digital display manufacturer about their displays’ dimming capabilities. Every Daktronics digital display features a photocell to adjust the LED brightness according to ambient light. Without brightness control, a display’s intensity at night can be so bright that its content will be unreadable and possibly offensive to some travellers.

After Installation of your Digital Display

Choose a manufacturer with the resources to provide excellent service after the sale to maintain display image capabilities, if it’s not in your best interest to continue servicing the display.

Daktronics offers after-the-sale service guaranteed to help keep your customers happy with the same sharp, uniform content the display exhibited the first day. Daktronics developed a field calibration technique that keeps colours across the entire display face consistent.

All displays require ventilation to increase the life of the display dramatically. Daktronics recommends changing and/or cleaning the vent filters at least once a year and making sure that the fans are operating correctly. Your area Daktronics technician can guide you through this process.

Daktronics also offers display monitoring. Technical Services uses a diagnostic program to monitor your display with visual verification by web camera technology and an intelligent controller. Trained staff watches for critical and non-critical errors and dispatches a technician to resolve these errors before they cause a problem.

Daktronics technicians undergo extensive factory training prior to working on displays running diagnostics, monitoring different conditions that may cause module or data errors, and addressing brightness control issues and display temperatures. Where factory technicians aren’t available, Daktronics uses Authorized Service Companies (ASCs) whose staff also follows rigorous training, meeting stringent standards. A network of ASCs across Canada and the US are ready to keep your displays looking great, year after year.

Offer your customers the most effective advertising medium they will ever own that looks as great year after year as it did when first fired up. Start with a display designed and manufactured to provide superior image quality and see that it stays that way with comprehensive field service support.
