Understand LED display Classification in an Easy Way

LED display classification that you may have not known



Man is a technology freak and wishes to evolve more and more. LED display market is no exception to the rule. Since the invention of LEDs, a continuous struggle is in progress for its smart usage. Today LEDs have successfully managed to become an integral part of our daily life. You can find LEDs in your smartphones, LED wallpapers, lighting solutions, and the most popular LED signage and LED billboards. Do you know that LEDs also have a cosmetic application? Yes! You heard it right. Today LED lashes and LED bionic contact lenses are available in the market too. Nowadays LED displays are available with a wide range of features and specifications. Always be specific about your requirements. For that matter, you need to explore LED display classification.


Let’s know the LED display classification


Like any other electronic product LED displays are also subject to innovation. You can find a variety of LED displays these days loaded with hi-end technology and sophistication. Actually, they are segregated and classified depending on a number of parameters and component material. The resultant display and pricing of the product are largely dependent on the selected class. To educate our readers further in this article we will be discussing LED display classification in detail.


Classification by placement


In terms of installation LED displays are classified into the following three categories


Outdoor LED signage: You will normally find these LED displays in the areas with maximum visibility. They have a larger surface area. Diluted pixel density gives a clear image quality from distances. They can work equally well in blazing sun and heavy rainfall. The screens of Outdoor LED signage are resistant to lightning and wind.


Indoor LED signage: These LED displays have relatively less surface area than outdoor LED billboards. The viewers are usually a few meters away. The pixel density is adjusted accordingly to make the visual content clear. It efficiency remains the same in ambient or bright lighting. The screens of the displays are neither waterproof nor weather resistant.


Semi-outdoor LED signage: These LED displays have characteristics middle way of both indoor and outdoor displays. The surface area is larger than indoor displays but lesser than outdoor signs. Featuring a sturdy luminous seal these displays function well under sunlight. The screen has a medium density. They are mostly installed on windows and roofs. It is an ideal way of smart utilization of space. Also, it imparts amazing aesthetics to the building.


Classification By LED Color


              led display classification



Depending upon the color of the light emitting diode, LED displays can be classified as follows


Single color or monochrome LED display: LEDs used in these displays contain only one color. Currently, we have five basic monochrome LEDs. These include single blue, single yellow, single red, single white, and single green. However, most clients prefer red LED due to its luminance. Red LED display screens are brighter. Text LED display screens normally use monochrome LEDs


Double color LED display: Each LED used in every pixel has red and green as base colors. Graphic displays usually work on double color LEDs.


Tri-color or full color LED display: This type of display contains three base colors which are red, blue, and green. Normally, video LED displays to constitute a full-color display.


Classification on portability basis


Depending upon movability LED displays are classified as:


Fixed LED display: Such displays are location point and do not move normally. Fixed LED display frames are usually made up of sturdy material like aluminum or steel.


Rental LED display: Businesses normally require such displays for a very brief period. They are ideal to present business in any exhibition. They are inexpensive as compared to fixed LED displays. Highlighting features of such displays include portability, quick mantling, and dismantling. They are light in weight to serve the purpose of easy transport and rapid installation. The cabinet and frame of rental Led displays mostly comprise of Die-cast aluminum.


Classification by control


On the basis of control, we have two types of displays.

Synchronous system display: In simple words, your LED signage will display what the computer display. This system display constitutes sending and receiving card along with related software. By inserting a sending card in the computer and a receiving card in screen a connection is established. Any changes required can be edited via software installed in the computer. Once you are satisfied with the content, transmit it via a sending card. Receiving card will receive the command thereby transferring to display screen automatically. Hence, the screen will telecast the program. A functioning computer is very important for synchronous system display. If any fault occurs or system crashes LED display screens will fail to operate.


Asynchronous system display: This display system is independent of a computer. An asynchronous display has both autoplay and storage function. It does not need a PC because the memory function is present in the sending card. This card is present in the cabinet and you can transfer content to a sending card through the computer. The whole process may or may not involve cables. Data transfer can take place over Wi-Fi, 3G, Ethernet cable, USB thumb drive or SD card. Programs once uploaded to the sending card will be transferred to a receiving card. The screens will show the content automatically. Even if the computer shuts there is no problem in running the content. Asynchronous system display possesses a unique feature of supporting multiple screen network.


Classification of LED displays according to distinct functions


On the basis of unique functioning LED displays are classified as follows


Strip Display: you will mostly find these LED displays for showing letters. There are several ways to input data. It can be done via a remote controller or simply by connecting with the computer. Data input is also possible under offline conditions. As the name indicate this LED signage is mostly in a strip shape.


Graph-text display: this form of LED display will display both graph and letters having no control for grey scale. For input purpose mostly they are connected to computers. It is slightly advantageous than conventional strip display. Why? Because it is capable of displaying a variety of fonts and graphs. Additionally, this graph text display works equally well in offline conditions. A single computer can control many graph text display simultaneously.


Digital mixed display: it is the most inexpensive form of LED business sign. Its major application is in financial institutions like banks and stock exchanges. It displays all relevant information including interest rates, currency exchange rates, price list, the market price of shares and much more. Strip displays when paired with the digital mixed display to show greeting remarks, important announcements and for advertising purpose. This type of display accepts input from a remote controller.


Video Display: The display elements of this class exactly corresponds to the pixels of the computer’s monitor. This computer is basically controlling the whole mechanism. It possesses 256 levels for the purpose of grey scale control. Hence, the expressive power is ample. At the same time, the display is aligned with multi-media cards. It is capable of playing video signals. There are plentiful advantages of video displays including software and system operation without limitation, open performance and reflection on the computer screen in real time.


Classification By Operating Current


            led classification



Depending upon operating current there are two classes of LED displays

Standard type: it runs at an operating current of 10mA to more than ten mA.

Low current LED: Such LEDs require a minimal operating current of less than 2mA (bear in mind that it offers the same brightness as standard LED).



Classification by luminous intensity


Based on luminous intensity we have

Standard brightness LED: the value of luminous intensity is lesser than 10mcd

High brightness LED: the luminous intensity ranges from 10mcd to 100mcd

Ultra-high brightness LED: The luminous intensity is greater than 100mcd


Classification by outer surface traits


Depending upon the outer surface characteristics of the diode LED can be classified into square LED, round LED, rectangular LED, surface mount miniature LED, side LED etc.


Classification by packaging


LEDs can be classified into glass packaging, full epoxy resin packaging, ceramic base epoxy resin packaging or metal base.


Classification by usage

To serve various purposes LED displays we have two types of displays


Conventional LED displays


Screen requirements: The conventional LED displays normally target less distant audience. So, their screen requirements are less. For indoor purposes P5 P4 models while for outdoors P10 and P16 work well.


Cabinet: the overall structure is quite heavy. The covering box will perform all waterproof treatments

Safety concerns: since these displays are not farthest and installed in a sturdy heavyweight frame it is less likely to get damaged.

Installation: Conventional LED billboards undergo fixed installation method. Their portability is very low. Hence, it is not easy to move them very often.


Surface mount LED displays

            led display


Screen requirements: Since the screen of such displays are installed at a high position, screen playback requirements are more stringent. The indoor version of surface mount displays normally use P3P4 model of the HD screen. Some conscious businesses even use P2.5P2. While for outdoor installation employ P6P5 models.


Cabinet: The box is normally in dismantled form. It is assembled as and when needed. Die- casting aluminum box is the chief ingredient of the cabinet.


Safety concerns: These display really demand sufficient measures for the safety of the screen. Although lighter than conventional LED displays yet it possesses enough weight. Because surface mount LED displays are installed high immense care is required while lifting and installing. Engineers are trying hard to further lean the structure keeping the screens light. Currently, it’s a die-casting aluminum box. Connections should be sturdy and reliable to prevent all safety threats while installation.


Resistance: Shipment of surface mount LED displays can occur by any medium i.e. through the plane, ship or by road. The edges of the display screens are very fragile. Bumps and jolts could possibly damage them. To counter this risk resistance level of surface mount LED displays are kept high. Slight damage to electrical components can ruin the normal display. Thus, the whole investment becomes zero.


Installation: Surface mount LED displays can be assembled on the go. Mantling and dismantling are super easy. For instance, a business can display its products in an exhibition. After the event, all screens are available for the next show at some other place.


Quick repair and replacement: Frequent transportation, assembly, and disassembly are the main reasons for recurrent wear and tear. The maintenance cost is high. So, it is advisable to quickly fix the screens to keep the repair cost low. Never delay repair and replacements because it can affect overall performance
