Understanding LED Signboard out of the Box




LED signboard




Defining in literal terms an LED sign or LED display comprises of flat panel display that displays video via light emitting diodes. Till now the definition is pretty simple but the scope, usage, and technicalities of this simple LED sign or LED display is beyond that.

Why not take an extra mile to discover the diversity of this sophisticated invention? But wait! We tend to educate the audience at large so we have tried to keep things both simple and understandable. Always remember choosing the right LED signboard partner is as important as choosing your life partner. Because both decisions can either make up or break up your life.


LED in simpler terms


An LED is an abbreviation of a light emitting diode. It is basically a semiconductor that radiates visible light while passing electric current. Mostly the light passing through LEDs is monochromatic i.e. taking place at a single wavelength. LED displays that embed single-bin LEDs of premium quality are trusted ones. Why? Because they are categorized via brightness or color value ensuring flawless and uniform content delivery throughout the operation.

LED signboard- fruitful investment


It is deemed that good quality LED billboard or digital display is one of the wisest investment business could ever make. Do you know that LED signboard can normally function for almost 11 years (approx. 100,000 hours)? Whooping figures isn’t it! Just imagine the business being marketed through LED billboards 24/7 without a gap. However, do keep in mind that the life span of LED displays could vary depending upon the manufacturing company. For instance, DAKCO is committed to delivering the best LED billboards and digital displays throughout the world. So do check out the safest possible option prior finalizing the deal.


Why LED signage is preferred?


Because of their operational efficacy. LED signage from a reliable source is energy efficient than conventional incandescent and fluorescent lights. Since LEDs do not employ filament in its working mechanism all energy is utilized in making light. No electric current is wasted in heat production. LED signboard can conserve up to 80%more energy than traditional signage. They convert 95% energy in light and waste only 5%. Previously incandescent signage used to have a recurring expenditure for changing bulbs. This costs almost an extra $200 or more monthly. LEDs, on the other hand, have comparatively longer operational life with minimal cost.


Digital displays impact the environment positively


An energy crisis is the modern world issue. It is also discussed that energy could be the main apple of discord among nations in the future era. So, efforts both at the individual and massive level are required to cut the power consumption. Since LED displays waste only 5% of energy, less power is required from the power plants to keep the operational activity. This in turn also affects the greenhouse gas emission. Precisely speaking LED display is the beneficial marketing solution impacting our environment in a friendly manner.


Digital display price


Finances have always been an important consideration in making choice. Same goes with buying an LED screen, digital display or LED billboard. Putting the right figures here is nearly impossible since prices vary according to the selected design, its working, structure, layout, dimensions and of course the source supplier. But to give you a hint it does cost in thousands of dollars or even more.

Never count this spending as an expense as this is your non-current asset. Why? Because it is going to reap economic benefits for years to come. One time investment but the right investment can skyrocket your business sales like anything.

Word of caution: you might get a low price quotation for your desired display, but recurring repair and maintenance cost could literally bore you tears. Finding the right LED signage provider like DAKCO is the real peace of mind. You can sit with peace of mind and enjoy materializing potential customers into actual buyers.


Let’s understand the digital display working


Every digital display constitutes three basic parts that work together to generate the output.

  1. Displays that are physically visible to the public or visitors and contain light-emitting diode. They are also termed as destination devices.
  2. External devices that continuously monitor and control the content being displayed at the screens or displays
  3. Microcontrollers that act as a link between both these parts i.e. displays and external devices. A smooth connection between all these parts ensures the correct presentation of the content.


Working mechanism


A light emitting diode is basically two-lead semiconductor light source. This diode is basically a p-n junction that radiates light when excited or activated. As soon as an appropriate voltage is applied to the leads, electrons get the potential to reunite with the electron holes of the display screen or device. The energy gets released in the shape of photons. This whole phenomenon is termed as electroluminescence. The viewer may be surprised to see the variation of color appearing on the display screens. The energy of photons dictate the colors of emitting light and it all depends on the energy band gap of the LED diode that comprises a semiconductor.


A quick summary of LED display working



  • The primary material used in display panels is Aluminum-gallium-arsenide (AlGaAs). In its organic form, a strong bonding is present between the atoms of this material. Now, as we all know that it is impossible to conduct electricity in strongly bonded atoms. Presence of electrons is mandatory for doing so.
  • The process of doping is carried out that actually means the addition of more electrons to AlGaAs. It is ensured that the balance of material gets effectively disturbed by doing so.
  • The stability of atomic distribution can be distorted either through injection or expulsion of electrons. Impurities added to aluminum-gallium-arsenide via doping possess the potential either to introduce electrons in the system creating an N-type or sucking out already present electrons creating a P-type, and forming holes in the orbits of the atom. The conductive properties are imparted to the material after doing all this procedure. Thus when exposed to electric current in N-type material electrons accomplish their journey from an anode to the cathode. The path becomes inverse for a p-type material.it is amazing to know that current never travels in the opposite direction in semiconductors.


A very simple known fact

  • when electron needs to gain position in higher orbital it requires energy push up to jump the orbit. Similarly, when it falls down it radiates energy. The phenomenon is well exploited in LED signage. By creating a p-type junction as a result of doping electrons fall from higher to lower orbitals thereby radiating photons of energy i.e. light. The distance among the orbitals is directly proportional to the intensity of light.
  • The striking, fluorescent or subtle colors appearing on the display panel owe their color appearance to varying wavelengths. Therefore genes of semiconductor play an important role in determining which light spectrum to emit. For instance,
  • Gallium Arsenide (GaAs) produces infrared light
  • Gallium-Phosphorus produces green or red light.
  • Gallium-Arsenide-Phosphorus produces yellow or red light



Separate LED signage for different visibility


Just as we use different power specs for far-sightedness and short-sightedness similarly client should be well aware of the exact make and model of LED billboards. Today, companies like DAKCO offers a free consultation to provide the most professional advice regarding LED displays. But to give the basic info, we will be discussing ‘’Optimal Viewing Distance’’. In simple terms, it means the point at which discrete pixels infuse or blend together such meticulously that it forms a uniform and meticulous image.

  1. For short distance viewership pixel to pixel distance should remain short. Normally 8mm Outdoor LED Digital Display devices are counted as finest for close viewership
  2. For large distances, wider pixel spacing is suited. 19mm models serve this purpose well. Remember that these digital signage need to be installed at a greater height to showcase the consistent image and target the public at large.


Homework before the final LED sign purchase


LED display board is not like a shoe that fits all rather it is purpose specific. Buyer should carefully work out the basic purpose of LED purchase. Of course, the LED display panel chosen for outdoors can’t be equally efficient for indoors. Similarly, wall mount displays will not do any good to outdoors. It is recommended first to identify where LED billboard is required. Pen down the requirements like pixel, pitch, and matrix.


Pixel is a cluster of LEDs grouped together. It may range from 1 – 25 in one pixel. However, the pixel count is determined by the pitch of the LED sign. Pitch is basically the distance between the centers of two pixels. The pitch largely defines the crispiness of the image appearing on displays. Knowing the exact pitch you need is really important for appropriate resolution. Just like a regular matrix that consists of rows and columns LED display matrix comprises of Pixel column (no. of pixel high) and Pixel row (no. of pixel width). The matrix tells the physical dimensions of any display panel. For instance, if the pixel height is 12 and pixel width is 48 then the matrix is 12*48.


LED density is another thing to watch for prior LED purchase. LED density is one of the key performance indicators for assessing LED display performance. The greater the number of LEDs per pixel the higher performance and brightness is delivered from the display panel. LED diodes drop 20% of initial brightness soon after first 2000 operational hours. After that, the deterioration rate slows down until the expiry of the product.



Perks of LED signs


  • LEDs can function well on very low current and voltage. A voltage range of mere 1 to 2 volts and 5 to 20 milliamperes of electric current are sufficient enough for LED working. Voltage or electric current requirement may vary for huge displays.
  • Rapid response time. The display device responds back in only 10 nanoseconds
  • Works well in every weather condition. Be it a blazing sun or heavy rain showers the display show never stops
  • An LED can survive for more than a decade. Some LEDs can even continue for up to 20 years
  • The digital signage does not need any bootup time
  • Visual, alphanumeric or any sort of content can be displayed via these digital billboards. Customization is easily available.


Digital signage- A quicker way to multiply your sales

Digital signage and LED displays are instrumental for any business. Public when choked in traffic usually spend their time viewing signboards. Since they don’t have the opportunity to change the channel like on TV, billboards usually get more viewer attention. Radio, TV and print media are bombarded with thousand products of a similar kind. It is harder for the reader to remember the exact brand and precise location of the business. Digital signage, on the other hand, stand alone and deliver the content in an optimal way. It is even easier for the viewer to retain the exact address and location of the outlet or brand store.



Dealing with the ferocity of the business world


Businesses that are new to the industry quickly reach out to the customer via LED displays installed at prime locations. Now the question arises why stable businesses require LED advertisement? The answer is pretty simple, to combat the competitors. Customer demand innovation and affordability, even for high priced products differentiation is required. The digital display is actually a communication medium between the seller and buyer. Businesses use this medium to continuously update public at large about their innovation, novel products, and reduced prices in short what make them different from others.



Flexibility of the LED sign


  • Whatever runs on the screen is completely under your control. There are no extra charges if you want to run your ad on the prime time slot.
  • Display screens market your business round the clock round the year with least cost
  • No middleman involved. The entire marketing process is hassle-free without salesman fee involved. Also, businesses can exactly communicate what they want to
  • Choose your own target audience
