VI. Virtual Pixel

PIXEL PITCH is the measurement from the center of one pixel to the center of the next pixel. Pixel pitch is measured in millimeter. 10mm, 12mm, 16mm, 20mm ,25mm, 31.25mm. 10mm is extremely close together you will have a clearer picture than compared to a 25mm. In the outdoor led world P10 is high definition with 928 pixels per square foot. Our most popular and economical display is our P20 with 232 pixels per square foot.

WHAT IS VIRTUAL PIXEL?
To explain what a Virtual Pixel is and how it works is difficult.We are going to look at 2 neighboring pixels. They are in a cluster of 2RGB. They are aligned in rows and columns. Virtual pixels allows one neighboring pixel to leverage (use) the neighboring pixel to help in making pictures and colors more smooth. Thus, reducing the pixilated look. A P20 will "look" like a P10, and a P16 will "look" like a P8.

Virtual pixel capabilities are enabled using better quality and more ICs on the module circuit board. The software must also communicate with the hardware to ensure optimal virtual resolution. See the image below.

THE MOST COMMON MISTAKE NEW LED USERS MAKE. is running their new led signs all day everyday. Remember ALL led screens need a break after running 72 straight hours. To preserve your investment every owner should schedule their digital led sign to AUTOMATICALLY turn off for a minimum of 4 hours after running 72 hours straight. Most customers schedule this down time every night (between the hours of 2-7am). Not only will this save money but, it will preserve the sign that much longer. This can be arranged using the software and users guide provided. We do this to prevent electrostatic discharge.

FREQUENT OR IMPUSE NEEDS
(compliments of ISA)

Businesses designed to meet frequent or impulse needs must reach out and pull people in on the spot. Examples of these include grocery stores, gas stations, hotels, video stores, restaurants, convenience stores, and car washes.

Many of these business's customers need to make a quick decision to stop. Therefore, their signage should be eye-catching with a brief, simple message that can be read and understood quickly. The businesses must be noticed and recognized at precisely the right time by those ready to buy. Often these businesses rely heavily on attracting tourists and need to be sure those unfamiliar with the business can tell right away what is sold there.

The typical McDonald's is a good example. The "golden arches" are such familiar icons that the McDonald's sign can be easily recognized long before the sign's lettering can be read. This gives a driver plenty of time to notice the sign, make a decision to stop, and safely maneuver through traffic. An independent fast food restaurant with a poorly-designed sign that is hard to see, hard to read, and hard to understand, will have great difficulty competing for the frequent need customer even if the food, service, and pricing are superior.

If your sign is going to convince the impulse customer to stop at your business, it must be designed so that the important information is easily recognized at a glance. People driving down the street can take in a great deal of information. Seventy-five percent will pick out the key word on a sign the first time they pass it. Make sure the first time someone reads your sign they immediately understand the most important information what you are selling. Any additional information should be designed to keep your repeat customers interested in your sign and your business so they remember to come see you again.

Because we read from the top down and left to right, the key word, graphic, or logo should be located at the top of the sign and read from left to right. Otherwise, the reader can get confused and take longer to understand the sign's message. This delay can mean the person who is seeing the sign for the first time is unable to read and react to it before driving past your business.

WIRELESS DATA TRANSMISSION

1. Radio Frequency

Perhaps the easiest and most cost effective way of data transmission. We install a little box inside the sign with and antenna. You then insert the mini modem drive into your usb port found on your laptop or desktop computer. This is designed to be a plug and play system. This form of data transmission is available with your full line of Bi Color and Monochrome-Red led signs.

2. Local Area Network (LAN)

We install a little box inside the sign with and antenna. You then insert the mini usb drive into your usb port found on your computer. With a little configuring you'll be up and running in no time.

3. Closed wireless network

We install a little box inside the sign with and antenna. You then insert the mini usb drive into your usb port found on your computer. With a little configuring you'll be up and running in no time.

DIRECT CABLE

CAT5 via RS232 plugs directly into the sign and into the usb port on your laptop or desktop computer. This is the most common and economical form of direct cable connection. Unless otherwise noted each digital led display will come with the cat5 RS232 interface. This method of data transmission is the most reliable, and capable of transmitting data up to 150 feet+.

VIEWING ANGLE VS READING ANGLE
Viewing a digital led display while standing directly in and in the middle of the sign this is the brightness and clearest the sign will appear. As one moves from the middle towards one side or the other the led display will appear dimmer and dimmer. As the angle becomes wider one will reach a point where the brightness is half of the initial brightness. This is the viewing angle.
