Using Your LED Display
The possibilities are endless. Your electronic sign can be a source of information, pride and even extra revenue! Here are just a few examples of how you can use your LED message center.
The graphics and text capabilities of your LED display will depend on its matrix size and model.
Please contact us for more information on these options.
Show examples in: Special Occasion Announcements
Display birthday greetings or wedding and anniversary announcements complete with digital photos, special effects and customized messages.
Show video clips from local events, parades, community fundraisers, holiday celebrations, parks & recreation sporting events and community center activities.
Alert drivers of traffic conditions and special restrictions in effect. You can program your sign to display different messages during all hours of the day.
Sell advertising space or acknowledge contributors. There are several ways to utilize your LED display as a significant marketing tool.
Serve the Community
Broadcast important information such as Amber Alerts, natural disaster hotlines, weather reports, even current time and temperature!
Why Does Brightness Matter?
There are two important things to consider related to the brightness of your sign: how well and how long it will compete with the Sun.
How well a sign competes with the Sun
Ensuring that your sign is readable during the day is vital to the success of having passers by read your sign. The brighter the display, the better able it is to compete with the Sun.
How long a sign competes with the Sun
LEDs do not burn out, however they do grow dimmer with use. The closer an LED gets to 1500MCD, the less effective it is at competing with the Sun. Starting with a brighter display ensures that your investment will be readable for many years into the future.
Stewart LEDs are among the brightest available to provide you with a sign that will be visible 24 hours a day, and for years into the future.
A light-emitting diode (LED) is a semiconductor device that illuminates when electricity passes through it. LEDs do not contain filaments like regular light bulbs, and they do not have delicate parts that break or burn out over time. Industry standard LEDs are rated at 100,000 (11+ years) of constant use.
A pixel is a point of light. An LED display is made up of an array of pixels, multiple points of light appearing as dots. A pixel can be as small as one LED or it may contain a cluster of LEDs that act as a unit.
Pixel Pitch (Center-to-Center)
The pixel pitch or center-to-center measurement is the distance from the center of one pixel to the center of the adjacent pixel. Pixel pitch can be measured in inches or millimeters.
The matrix of a sign is the number of pixels vertically by the number of pixels horizontally. For example, if a sign has a matrix of 32x96, this means it has 32 pixels from top to bottom and 96 pixels from left to right. A larger matrix allows more text and more of a graphic to appear on the display at the same time.
A millicandela is a unit of measurement for the brightness of a single LED. A millicandela is equal to 1/1000 of a candela, which is comparable to a single candle's brightness.
A nit is a unit of measurement for the brightness over one square meter of a display. This value takes into account the number of LEDs per pixel, pixel pitch and millicandelas. Your sign's nit rating can help you determine which sign is a better value when comparing products and companies.
Viewing Angle & Viewing Cone
The viewing angle is the maximum angle that text and images can be seen on a display. A narrow viewing angle causes the text or image to "disappear" from the display as a viewer moves away from a position directly in front of the sign. The viewing cone is simply double the amount of the viewing angle.
We are very pleased with the sign and have appreciated the warm and caring way which you dealt with our church.
