What attentions need to be paid when using an led display screen

Led display screen is an emerging technology. Today, it can be used in every industry and organization to support their brand, services and operational business strategies. It brings a competitive advantage, increases conversions and improves business performance when used effectively.
Led display screen has the potential to give your business or organization a more rewarding environment. However, it is important to remember that in LED Displays etiquette still matters. Being a good neighbor is essential in making a positive impact on the community.


Here are the attentions need to be paid.
  1. Brightness level
The brightness level should be visible, readable and conspicuous enough to be effective. A digital LED sign should be easily viewable even when exposed to direct sunlight. Poor anti-reflective treatment and inadequate brightness will put an outdoor digital display solution to waste. On the other hand, having a screen that is too bright will be difficult for viewers, especially motorists, to see.
The brightness level of a digital sign at night is an issue that the sign industry and community deal with. It can be distracting, unreadable and ineffective when programmed to be too bright at night.
Using a signage software control system that allows a scheduling of brightness levels is key. Most LED signs are already using technology to ensure an appropriate brightness level. They are designed to produce sufficient brightness to ensure clear legibility during daytime and change its brightness settings during night time hours. You can use the program to set the time the sign brightens as well as the time that it should dim.
Other advantages of appropriate brightness levels include:
  • Legibility of display content
  • Energy conservation
  • Set community goodwill
  • Increase digital signage life expectancy
  1. Content strategy
It is important to use your digital signage to its full potential. Remember that your goal is to attract attention and deliver useful information. Your message can get lost in too much clutter on the display. It will create confusion and viewers may have a hard time understanding your message or just ignore it completely. Don't risk your signage sabotaging your marketing efforts.
What to avoid:
  • Too much text
  • Too much color, images and motion
  • Complex messages
  • No content hierarchy
Keep your content simple and appropriate. Be subtle with content and colors. Also take note of your slide timing. The recommended time is from six to 10 seconds per slide.
Limit your display content to one idea. For instance, instead of paragraph-length safety tips, show it in a brief sentence: "Caution! Construction in Progress"
Make your viewers focus on one idea or call-to-action. It is easier to digest a simple message than cramming multiple events in one slide. 
  1. Power On and Off
Digital LED signs that are used for traffic control, transportation information, emergency messaging or government use are required to run 24 hours a day. Business and commercial signage can operate on their own hours.
Businesses that are just in operation for certain hours don't need to have their signs on at all times. In some instances, it is advisable to leave the screen of an indoor signage in operation if it's visible through the windows. 


All digital displays have a limited lifespan. One of the best ways to extend this investment is to limit the hours of operation. Not only does it decrease maintenance costs, but also gives you major power savings.
How to do it:
  • Just like with the brightness level, you can use software controls. Set your displays to turn off and on each day to preserve its lifespan. The more up-to-date digital displays can be scheduled to turn themselves on and off automatically.
Hint: 
During the colder seasons, LED signs take more time than normal to boot up, so schedule the power on a little bit earlier. 
  • Dim the screen to zero nit intensity. This method keeps the LED sign and the computer on-line and powered-up. This does not require a full start re-boot.
Led display screen is a valuable addition for your business or organization. While using your digital signs, remember to be a good neighbor within your community.

Best strategies of selling led display

led display has become widely used - from restaurants to retail stores, banks, business offices, government institutions, churches and more.


Taking time to understand all information about a product is a great start to marketing that product. Obtaining an in depth perspective about how the product can be utilized when selling led display solutions ensures you are reaching all potential customers.


When selling led display, don’t think of yourself as just a sales person. You are selling more than just a sign; you are entering a long-term relationship.
The key to selling is to create solutions that add value to your customers.


Daily Dollar Cost Approach


When it comes to cost, new led display customers often think purchasing LED signs are too expensive. If you evaluate the ROI impact of how sales increase verses the cost of owning a digital sign in terms of dollars per day, LED signs can pay for themselves in less than one year based on your average daily sale!


For instance, the payment period for a $12,000 LED signage is 2 years or 24 months.


Cost per Month = $12,000/24 months = $500 per month


Cost per Day = $500/30 days = $16.66 per day 


Make the customer see that minimal amount they need to spend on their LED signage each day.


Current Advertising Budget Restructuring Approach


It is important that every business has budget allocations for marketing and advertising. However, some business owners see that purchasing an led display would be just an additional expense that adds to their advertising budget.


The solution here is to make the customer see that they can allocate the funds in their existing budget to their led display purchase. Ask your customers how they utilize their advertising budgets. Do they use traditional or broad-based advertising?


Ask follow up questions like, "May I ask how much you allocate per month advertising your business?"


The challenge here is to let the customer see that purchasing a digital sign more cost effective than their current advertising budget.


Return on Investment Approach


Business sales and revenue are likely to increase by using led display, since LED signage is an effective way to advertise. In general, it is possible to see an increase of about 25-30 percent, depending upon strategic content, the company’s current campaign, and the location of the sign. 


For instance, a small business does $300,000 yearly sales with 35 percent sales margin.


With the use of LED signage, the sales will most likely to increase to $375,000 per year. If income is projected to increase by 0.35, then profit before taxes is about (0.35 x 75,000) = $26,250.


If the total cost of the LED signage is $25,000, then your customer can still have additional $1,250 savings.


The challenge here is to make the client see the impact of having an led display - from driving more sales to paying the sign fully.

More Strategies to Sell LED Signage
  1. Up-Sell with Information. Don't just simply talk about the cost and the terms of your led display. Provide your clients with helpful information instead. Educate them on how they can effectively use their digital sign. Demonstrate the countless options they have with the types of images, graphics, fonts, and styles they can use to develop their brand.
  1. Demo It. Most clients know what they want, so give them a "proof of concept." For instance, a local coffee shop needs some help rebranding. Pull their menu or current promotions from their website and use it when you set-up a demo unit in the store. Make your client see the impact and effect it has on the coffee shop customers.
When selling to a client, it is important to build trust. As you guide them towards proper purchasing decisions, not only will your sales improve, but also their loyalty and your relationship as well.

Key points for a good full color led display


1. The full color led display surface roughness should be within + 1mm, to ensure that the display image does not distort. Partial convex or concave can lead to blind visual angle of the display screen. The flatness is mainly determined by the production technology.
 
2. Brightness and visual angle. Full color led display brightness need to be up to 800cd/m2 and outdoor display be up to 1500-10000cd/m2 to ensure that people could see clear and vivid images. The brightness is mainly determined by the LED chip, but too high brightness would shorten the lifetime of LEDs, so it’s not a must to improve the brightness excessively. Nowadays for indoor display require low brightness and high gray scale, generally brightness among 800-1000cd/m2, and gray scale 16bit. The visual angle of display decides the audience quantity, so the better visual angle, the better. The display visual angle is mainly determined by LED chip encapsulation method. So far, the SMD visual angle is up to 140°, compared with DIP, it has better visual effect.

3. White balance effect, is one of the most important indicators of full color led display. In color science, when red, green, bule colors ratio reach 1:4.6:0.16, it shows pure white color. If the actual ratio exists deviation, white balance will appear deviation. Normally we need to pay attention if it exists partial blue or partial green-yellow appearances. White balance is mainly determined by the control system.


4. Color reductibility, it means the color reductibility of the images. The screen displaying color need to keep highly congruent with the play source color, to ensure the authenticity of the image.

5. If there is mosaic and dead light. The mosaic means constant bright or black block in the display. It’s called led module necrosis. The main relevance is the display connector quality. The dead light refers constant bright or black point in the display screen. The quantities of dead light represent the quality of LED chip. TCB led display products have 72 hours aging test before shipment, eliminating dead light issue and show clients prefect products.


6. If there is color lump. It refers to the obvious color difference between adjacent modules,. Different batch of full color led display might exist tiny color difference.
