LED technology paved the way for the introduction of many innovative devices into the world, including LED Displays. And since their introduction, they have been part of people&#;s way of life, whether in the privacy of their residences or public spaces. There are different LED display types you will discover wherever you are walking or staying.
Many would usually associate LED display with a flat TV screen, which is why it is often confused with LCD displays. The truth is that they can come in a variety of items, from mobile phones and PC monitors to conference displays and gigantic commercial signages.
Light Emitting Diode or LED refers to the material that glows up when electricity touches it. These semiconductors are known to be long lasting and highly efficient compared to traditional lighting. For LED displays, this simply means that rows of LED semiconductors are installed to deliver backlight for the screen instead of the standard CCFL tubes in LCD displays. The efficiency and better light control also translate to the performance of the displays.
LED displays come in a variety of forms. The most common LED display types that you&#;ve probably come across are digital clocks and timers and even basic calculators. These are simple indoor LED message displays and there are more gigantic and complex setups than these like large-scale LED video walls and public information LED text displays.
LED displays have become ubiquitous in the market because of their variety of applications.
They may include different configurations, including alphanumeric versions and segmented displays. You can group the different types based on several factors, including based on their content, their technology, and the purpose of the screens. Let&#;s start with the different types of LED displays you can encounter based on content.
The different types of LED displays based on content are evident in what they display. Here are some of the LED display types under this category.

This LED Display type pertains to screens that are structured to show text and alphanumeric data. They are designed to be limited only to this type of content. They are customized and pre-programmed with the text you want to be shown on the screen. One of the most popular Text Display LEDs is the storefront OPEN/CLOSED label in restaurants. Since these displays are fixed, you cannot change them to other text info.
Image Display LED is a more complex setup compared to a text display. It has a pair of LED screens that allows the display to show both text and images at the same time. Both the text and images are stationary, which makes this type a popular choice for a simple billboard display.
This type of LED display shows both text and images (only stationary) at the same time. It&#;s possible because the LED lights are positioned in a row. The text can also move if that&#;s what you prefer. This is what makes it different from the text LED display.
These LED display types tend to show a variety of text in motion, making them different that the text LED display. Lattice LED displays are popular in airports and sports centers. For the former, they show flight details while the latter displays statistics and scores.
The Digital LED display can only show numbers. This limitation is what makes it varied from the text LED display. The LED lights are arranged around the screen. They are also all pointing toward the center.
The numbers are usually glowing in orange or red light, depending on how they are designed. The most common place you can see these displays is the bank with all their digital clocks and currency information.
The most trendy type used today, a video LED display is what you will see in tourist attractions like Times Square in New York. These LED displays feature high-pixel LEDs that offer high-resolution moving images.
With the continuous advancement of LED technology, different types have been introduced and are currently used for LED displays. Deciding which one is the best may be difficult to pinpoint since you would have to consider other factors like its usage and location for installation. To be able to decide on your own, here are some of the LED display types based on the technology they use.
The ELED display refers to a screen that uses edge-Lit LED technology. LED lights are arranged around the screen and point toward the center. The light is spread evenly across the screen.
Benefits
Downside
This LED display is one level better compared to ELED when it comes to evenly light distribution. This is due to the grid pattern that the LEDs are arranged in from one end to the other. The diffuser also receives light, which contributes to its even distribution. The technology in these LED display types is normally used in low-end to mid-range quality televisions.
Benefits
Drawbacks
A full-array LED display is a backlight screen notable for having its entire back covered in LEDs. These LED lights are arranged in groups and in different zones to allow better control of their functions. They deliver more robust color contrast and brightness compared to ELED displays.
Benefits
Drawbacks
RGB is popular nowadays because of the rise of eye-catchy gaming accessories you will see in avid gamers and streamers. R (red) B (blue) G (green) refers to the LED light colors that are installed on the screen. The red, blue, and green lights help make it possible to produce colorful and catchy images. The combination of these colors creates pure white that allows the truer shades on the board.
Among the different LED display types, RGB is known for its flexibility in colors that can be used to produce varied color component results. The red, green, or blue LEDs can be heightened depending on the chosen color.
Benefits
Drawbacks
Organic LED or OLED is another type of LED display where the screen itself can produce its light once the current hits the board. This is way different compared to the first LED display types with the LED light and the display separate from each other. Without fancy crystals and layers, each sub-pixel lights up once electricity is applied, producing different colors.
This type of LED display is known as organic LED because it uses organic compounds that include Triphenylamine or Polyfluorene. It also has HDR or High Dynamic Range programming to operate brightness and color levels.
Benefits
Drawbacks
Micro LED displays are LED display types that are designed based on OLED. Micro-LEDs use inorganic light-producing materials, which is its main difference from OLEDs. They are approximately 0.002 in size, which makes it possible to have the screens in small dimensions.
Benefits
Drawbacks
The Quantum Dot LED display uses the typical blue LED backlight of the standard LCD-LED screen which goes through a red and green quantum dots filter (semiconductor nanocrystals) and turns it white. Red, blue, and green are the LED colors you can find on the board.
Benefits
Drawbacks
Mini LED display is one of the two LED display types based on another type. If the micro-LED display is based on OLED, the mini-LED is based on the design of the standard QLED display. Mini-LED displays use numerous and significantly smaller LED lights than QLED, which makes them widely varied from the other.
Benefits
Drawbacks
There are two LED display types that are based on where you plan to use them. They are easy enough to understand since they are named based on the location they are found and installed in.
This type of LED display is usually found indoors and for private use, whether for your family&#;s usage or the company you work for. The most popular ones are the indoor LED screens installed inside a building like in the central reception hall, meeting rooms, and large conference spaces. They are also found in sports halls and complexes in the form of scoreboards and replay displays.
This is one of the LED display types that may be considered as catchy and grand in its installation. There are many different LED displays under this category primarily due to marketing activities and advertising efforts. They provide strong visibility perfect for a wider market reach. Here are some LED screens under this group.
There are many LED display types to consider and there are also many factors you have to take into account when deciding which one to choose. To give you a rundown, some of these factors include your budget, the purpose of the LED display application, and the location of the installation. Once you&#;ve considered them, you can make an informed decision on which LED display to invest in.
