What is LED?
Using an array of tiny light-emitting diode (LED) modules as individual pixels to produce vibrant and crisp images, LED displays directly emit light without the need for a separate backlight. This technology not only makes LED TVs and LED monitors produce vividly dynamic imagery, but it also lowers power consumption and reduces the environmental impact. Other advantages of LED displays include:
- Color accuracy. Reproducing colors as faithfully and accurately as possible, LED displays offer excellent color accuracy.
- Brightness and visibility. Precise brightness control enhances comfort and optimizes the viewing experience.
- Longevity. LEDs have a longer lifespan than most other lighting and display technologies, saving on maintenance and repair costs.
With the ability to combine energy efficiency with breathtaking visuals, LED screens are the preferred choice for a variety of applications.
What is OLED?
Although they rely on similar technologies, what sets organic light-emitting diode (OLED) displays apart from traditional LED displays is their unique self-emissive property. In OLED TVs and OLED monitors, each individual pixel emits its own light when an electric current is applied, allowing for true blacks and infinite contrast ratios. Other advantages of OLED screens include:
- Vivid and accurate colors. Colors are reproduced with high accuracy and vibrancy, achieving a wider color range and providing excellent color saturation.
- Fast response times. Delivering lightning-quick pixel transition, fast response times help eliminate motion blur and promote crystal-clear images.
- High refresh rates. The display is updated more frequently with higher refresh rates that results in smoother motion while reducing input lag.
The superior picture quality of OLED screens does deliver better graphics, but they aren’t as widely available or popular as LED displays.
Differences between OLED and LED displays.
As you can see, both OLED and LED screens have their own set of characteristics and advantages. But, how is OLED different from LED, exactly?
Each pixel in an OLED display generates its own light. This self-emissive nature allows for individual pixel control, resulting in true blacks and high contrast ratios. This is different than the backlighting system used in LED technology, which is positioned behind a liquid crystal display (LCD) panel. The LCD panel modulates the light emitted by the LEDs to create an image.

Read More
New ways to attract, convert, and process potential customers develop every day and if you want to stay relevant in today’s competitive market, you need to be dynamic with your marketing efforts. Commercial digital signage offers a unique opportunity to impact your audience. It’s fluid in nature, allowing you to change your display throughout the day, and has been proven to attract more attention from those walking or driving by. Digital signage has limitless possibilities and can help you improve your business through insightful analytics in more ways than one. However, finding the right type of digital signage for your business needs isn’t as straightforward as you’d think. There are a few different types of signage options on the market, each with unique features. To help you choose which option is best for you, we’re here to answer a common question: what are the different types of commercial digital signage?
What is Commercial Digital Signage?
Choosing Between Consumer and Commercial Digital Signage
If you need digital signage for your business, the choice is fairly clear. Commercial digital signage offers more benefits than a consumer TV display. They’re made using minimal design features so they can seamlessly blend into the environment yet have the durability to run non-stop for long periods of time without burnout. Digital signage for commercial businesses also utilizes technology to improve readability under all conditions—especially when outside in direct sunlight. They have built-in media players, improved connectivity, and features that can be controlled without a remote.
Consumer displays, on the other hand, are essentially your standard family room TV. They’re meant to be used intermittingly as entertainment, not continuously for advertisement. To further your business’ marketing goals, commercial digital signage is a better option. However, there isn’t just one type of digital signage for commercial use, so it’s important to understand the differences to make the best choice for your business.
Different Types of Commercial Digital Signage
If you’re considering getting digital signage for your commercial business, you’ll want to research your options before making a purchase. While the different types of signage all use good technology, the application in which you’ll use them matters. Since they’re a larger upfront investment, choosing the right type of signage will help you avoid wasting money. Here are the primary types of commercial digital signage.
1. Commercial LED Digital Signage
Commercial LED digital signage uses a network of LED lights or “pixels” that, when viewed together, produce an image. The saturation of pixels in the display, also referred to as pixel pitch, influences the image resolution and clarity. Commercial LED displays can be made into different shapes using an interconnected network of panels. They can be constructed together for large-scale video since they aren’t limited by bezel lines, which create visible breaks in your image across screens. This provides a certain degree of flexibility as they can be wrapped around objects, curved, and configured into any size or shape. Some of the common challenges of LED digital signage include low resolution, high energy consumption, and light pollution.
2. Commercial LCD Digital Signage
LCD stands for “liquid crystal display“. LCDs are made of multiple layers which work together to produce an image. The base layer is comprised of the lighting technology, and the LCD cell sits atop. The LCD cell is made up of three layers: a bottom plate, liquid crystal, and a top plate. An additional layer of strengthened glass is added to provide protection and anti-glare/anti-reflective qualities. There are two primary types of commercial LCD signage: high-brightness LCDs and reflective LCDs. The primary difference between the two is within their lighting technology.
High-Brightness LCDs
Conventional LCDs are great for use indoors or in low-light environments, but become difficult to read when placed outdoors, especially in direct sunlight. To achieve sunlight readability, LCDs can be built using high-brightness backlights. This method provides good sunlight visibility, but causes some other challenges. High-brightness backlights require a lot of power (and cost) to operate. They also produce heat, which must be combatted with temperature control systems to prevent burnout. These temperature control systems increase the bulkiness of the display, making them less convenient for certain locations.
Reflective Color LCDs
Reflective color LCDs provide the same stunning imagery as other types of LCDs, but they utilize reflection to illuminate the display rather than a backlight. When ambient light passes through the LCD cell from the front, it’s reflected back to the viewer by the mirror-like layer and subsequent technology. This is incredibly beneficial in outdoor settings with lots of sunlight. The brighter the sun shines on the display, the brighter the display image gets. Furthermore, the absence of a backlight helps to drastically reduce power usage – less than 5 watts to be exact! In fact, Sun Vision Display’s 32″ reflective color LCD signs operate on 95% less power than similarly-sized high-brightness LCDs or LED signs. Other benefits of reflective color LCDs include reduced blue light radiation, low heat production, portability, and battery-operability.
Though reflective LCD technology has been around for several years, it has only recently become available in large enough sizes useful for digital advertising applications through brands like Sun Vision Display. If you’re interested in adding commercial digital signage to your outdoor marketing efforts, especially for areas with high sun exposure, contact BaoVision Display to learn more.
3. Electronic Paper Displays
Another low-power, sunlight readable solution are electronic paper displays, also referred to as e-paper or electrophoretic displays. Epaper signage utilizes a bistable, reflective LCD technology that creates a black and white image that appears similar to ink on paper. They only require power to change the image, making them an excellent low-power solution for sunlight visibility There are a number of types of epaper display technologies including E-Ink, ZBD LCDs, and more. Not all of them are available in large-format sizes suitable for advertising. And, they can’t produce the full spectrum of colors like other LCD technologies. But they are a great solution for many applications.
There are so many benefits to using commercial digital signage. While the initial upfront costs are going to be higher than traditional advertising methods, your return on investment is much higher. When choosing your signage, make sure that you weigh your options and find the best display for your needs. If you have any questions or would like to discuss options for your business, contact the professionals at BaoVision Display.

This article provides a detailed comparison of these two display technologies, helping you understand their strengths and weaknesses in outdoor environments, and offering professional advice for choosing the right display screen.
1. Basic Concepts of LED and LCD
LED (Light Emitting Diode) Display: An LED display uses LEDs (light-emitting diodes) as its light source. LED displays can be categorized into two types: direct LED displays (used in TVs, monitors, etc.) and LED backlit displays (used as a backlight for LCD panels). Outdoor advertising and large-screen displays usually refer to direct LED displays.
LCD (Liquid Crystal Display): LCD displays use liquid crystal technology, where the liquid crystal molecules are illuminated by a backlight to display images. LCD displays are widely used in TVs, mobile screens, computer monitors, etc. Although liquid crystals themselves do not emit light, brightness is provided by a backlight, typically using LEDs.
2. Performance of LED vs. LCD in Outdoor Environments
In outdoor environments, displays must endure intense sunlight, weather changes, temperature fluctuations, and prolonged usage. Therefore, the performance of LED and LCD displays in these conditions differs in several key aspects:
Brightness
- LED: LED displays generally have higher brightness, maintaining clear visibility even in direct sunlight. LED screens have adjustable brightness and can typically reach over 8000 cd/m², making them ideal for outdoor advertising, live sports events, and other high-brightness scenarios. This high brightness ensures clear visibility even under direct sunlight.
- LCD: LCD screens typically have lower brightness, usually ranging from 300-600 cd/m². While some high-end LCD screens can reach around 1000 cd/m², they still struggle to provide sufficient clarity in intense sunlight. As a result, LCD screens are more suitable for indoor or low-light environments, with poor visibility in direct sunlight.
Conclusion: LED outperforms LCD in terms of brightness, making it more suitable for outdoor environments with strong sunlight.
Viewing Angle
- LED: LED displays have a wide viewing angle, maintaining stable display quality from various angles. Even when viewed from large angles, the color and brightness remain consistent, making LED displays ideal for large outdoor billboards or sports venues.
- LCD: LCD displays have a smaller viewing angle, especially with traditional backlit liquid crystal displays, where the colors and brightness can shift significantly as the viewing angle changes. Although some high-end LCDs use IPS technology to provide a wider viewing angle, they still fall short compared to LED.
Conclusion: LED also excels in terms of viewing angle, offering a better viewing experience.
Weather Resistance
- LED: LED displays have strong weather resistance and can adapt to various harsh weather conditions, such as intense sunlight, high temperatures, low temperatures, and humidity. Most outdoor LED displays are designed with an IP protection rating, ensuring dustproof, waterproof, and moisture-resistant capabilities, making them suitable for long-term outdoor use.
- LCD: LCD displays have weaker weather resistance, particularly because the components of the backlighting system are generally not as durable as LEDs. Prolonged exposure to outdoor environments can cause damage from temperature differences, humidity, and rain, negatively affecting the display’s lifespan and performance.
Conclusion: LED displays outperform LCD displays in environmental adaptability, making them more suitable for unpredictable outdoor conditions.

- LED: LED displays are energy-efficient because they use high-efficiency light-emitting diodes, consuming less power than LCD screens. Additionally, LED displays typically have a longer lifespan, often exceeding 100,000 hours, significantly reducing maintenance costs.
- LCD: LCD displays have relatively lower energy efficiency since their backlighting system requires extra power. While modern LCD technology has improved, LCD screens generally have shorter lifespans compared to LED displays. High-brightness LCDs often experience faster light degradation, requiring more frequent maintenance.
Conclusion: While LED displays were initially more power-hungry, the gap between the two technologies has narrowed, and LED’s advantages in other areas outweigh this minor disadvantage.
3. Suitable Applications of LED and LCD
Based on the above comparison, it is clear that LED displays generally perform better than LCD displays in outdoor environments. Below is an analysis of the suitable applications for both technologies:
LED Suitable Applications
- Outdoor Advertising: LED displays are the best choice for outdoor advertising, particularly in high-brightness environments like billboards, storefronts, and traffic signs. The high brightness and weather resistance of LED screens ensure that the content remains clearly visible under strong sunlight and that the screen can function in all weather conditions.
- Sports Venues: LED displays are widely used in sports stadiums for scoreboards, advertising, and video playback. Due to their high brightness and wide viewing angles, spectators from any angle in the venue can clearly see the screen content.
- Large-Scale Events and Concerts: LED displays are commonly used at large outdoor events and concerts to showcase performance content, live video feeds, lighting effects, etc. Their high brightness, wide viewing angles, and flexible modular design make them the preferred choice for such events.
LCD Suitable Applications
- Indoor Displays: LCD displays are more suited for indoor environments such as conference rooms, exhibitions, and in-mall advertising. In darker environments, LCD screens can provide stable display performance, and they are usually more cost-effective.
- Low-Brightness Outdoor Applications: LCD displays are suitable for outdoor environments with low brightness requirements and shorter usage durations, such as information displays at outdoor bus stations or small street-side billboards.
Case 1: LED Advertising Screens in Times Square, New York
Times Square in New York is famous for its large LED advertising screens. These screens use high-brightness LED technology to ensure that the content remains clearly visible even under intense sunlight. The LED screens in Times Square offer high resolution, wide viewing angles, and strong weather resistance, making them perfect for extreme weather conditions.
Case 2: LCD Advertising Screens in Shanghai Metro
Shanghai Metro, one of the busiest subway systems in the world, has installed numerous outdoor LCD advertising screens in multiple stations and trains. These screens are used for displaying ads, announcements, real-time information, and entertainment content. The primary goal of the metro’s LCD screens is to showcase ads, commercial promotions, and real-time train information.
5. Conclusion
LED displays undoubtedly outperform LCD displays in outdoor environments. The high brightness, wide viewing angles, weather resistance, and energy efficiency of LED make them the top choice for outdoor advertising, sports events, concerts, and other large-scale events. On the other hand, LCD displays are more suitable for indoor environments or outdoor applications with lower brightness requirements. For outdoor scenarios that require clear visibility under strong sunlight and long-duration use, LED is the better choice.
When selecting an outdoor display, it is important to consider your specific needs, budget, and the requirements of the environment. By taking into account factors such as brightness, weather resistance, and visual performance, you can choose the display technology that best meets your needs.
