In the ever-evolving world of display technologies, two terms often come up: LCD and dvLED. These technologies, while sometimes used interchangeably, have distinct characteristics, each with its own set of advantages and disadvantages. In this blog, we will dive into the differences between LCD and dvLED displays, exploring the technology behind each and weighing their pros and cons.
In partnership with Fluid Sound, PixelFLEX added a captivating dvLED display in Sharp Healthcare‘s lobby area.
LCD Technology: A Detailed Look
LCD technology, which stands for Liquid Crystal Display, relies on a unique method of manipulating light to display images. It uses a backlight, typically made of fluorescent or dvLED lights, that shines through a layer of liquid crystals. These crystals can be aligned or twisted to allow varying levels of light to pass through them. This light then passes through a series of color filters to produce the final image that appears on the screen. The ability of the liquid crystals to block or allow light through in response to an electric current is what makes the display possible.
Advantages of LCD
Ideal for Smaller Areas
LCDs are great for smaller spaces where viewing distance is not an issue. The panels are typically very thin and have a flat design. This makes them space-efficient and ideal for small rooms where larger displays might not fit well.
Resolution
Pixel pitch resolution becomes less critical when viewing up close with LCD screens because, at a close distance, individual pixels become less noticeable to the human eye.
LCD screens typically have high pixel densities, meaning there are numerous pixels per inch, resulting in finer details and smoother images. When viewed up close, the small pixel gaps between individual pixels blend together, creating a cohesive and visually pleasing image.
Software and OS Compatibility
LCD screens often come with software, a mini player, and are usually compatible with Android, Tizen, or WebOS operating systems.
The software enables content management, easy updates, and customization, while the mini player and OS compatibility ensure seamless operation, app support, and a user-friendly interface, making LCD screens versatile and user focused.
Cost-Effectiveness
Generally, LCDs are a lower-cost solution than dvLED for close-up viewing needs. This is beneficial when the screen size can be minimized, and bezels are not an issue for stacked displays.
Durability
LCD screens are less likely to get damaged when touched. They are also a durable option due to their solid-state design, which lacks moving parts that can be prone to wear and tear, increasing longevity.
Warranty
Standard 3-year warranty.
A collection of LCD screens cluster together to create a larger image. Patrons can see the bezels of the screens, which take away from the overall visual appeal.
Disadvantages of LCD
Size and Weight:
LCD screens often feature heavy glass and large cabinet designs, making them bulky. This becomes a significant issue for large displays (86” to 100”), which are difficult to fit in elevators for installation.
Installation Challenges
Due to their weight, installing LCD video walls can be complex. They require stronger mounting supports, which leads to higher costs.
Inconsistencies in Video Walls
When used in video walls, each screen can have different color and brightness calibration, leading to inconsistencies in content viewing.
Limited Lifespan
Typically, LCDs are rated at 50,000 hours to half-life. Over time, LCD screens experience a slow and gradual loss of vibrancy in colors, referred to as “color fading,” which occurs at a gradual pace, maintaining acceptable display quality for an extended period.
Shipping and Installation Risks
LCD screens can be prone to cracking during shipping and installation due to their relatively thin and fragile glass panels. Handling errors, impacts, or rough transportation can lead to structural damage, resulting in cracks or breakages, highlighting the need for careful packaging and installation procedures.
Bezels
A bezel is the frame or border surrounding the active display area of an LCD screen.
LCDs have noticeable bezels between screens, which can be distracting, because these bezels create physical gaps between multiple screens when they are arranged in multi-monitor setups, interrupting the seamless flow of content and causing visual discontinuity, which can be distracting to viewers.
Image Quality and Viewing Angles
Compared to newer technologies like that of dvLED or Quantum Dot displays, LCDs generally have lower contrast ratios and limited viewing angles, which can affect the visibility and vibrancy of the content displayed.
Energy Efficiency
While LCDs with dvLED backlights are more energy-efficient than their older CCFL counterparts, they still lag behind newer display technologies in terms of energy consumption and heat generation.
Response Time and Refresh Rates
LCDs typically have slower response times and lower refresh rates compared to newer technologies, which can result in motion blur and less smooth rendering of fast-moving images – a downside for dynamic advertising or interactive applications.
dv LED Technology: A Modern Approach
dvLED, or Direct View LED, represents a more modern approach. dvLED technology, which stands for Light Emitting Diode is fundamentally different from LCD.
In dvLED displays, each pixel is its own tiny LED light. These LEDs emit light directly when an electric current passes through them, eliminating the need for a backlight and liquid crystals used in LCDs. This direct light-emitting process allows for higher brightness, more vivid colors, and greater energy efficiency.
Curved LED panels that be be created with products, such as PixelFLEX’s FLEXMod, can provide an elevated viewer experience at venues and events.
Advantages of dvLED
Ease of Installation:
dvLED displays are easier and less costly to install than LCDs because they are typically lighter and thinner, reducing the structural requirements and installation complexity. Additionally, dvLED displays can be custom-sized and easily assembled into large screens, minimizing installation time and labor costs.
Longevity
These solutions are rated at 100,000 hours of operation, which is significantly longer than LCDs, ensuring extended lifespan and durability. Moreover, dvLED displays maintain their vibrancy over time, as they do not suffer from color fading, providing consistent and vibrant visuals throughout their extended lifespan.
Outdoor Visibility
Brighter solutions are possible with dvLED displays that are most suitable for outdoor environments. This is due to their ability to emit high-intensity light, even in direct sunlight.

Birmingham, Ala., April23, 2013— Student Life, an inter-denominational ministry offering Gospel-centered, high energy summer camps and youth conferences, has taken PixelFLEX’s ultra-flexible and lightweight LED curtain video wall on the road during its Be Last Conference celebrating Mark 9:35: If anyone would be first, he must be last of all and servant of all.
On the tour, Student Life uses 16 PixelFLEX panels across the stage as an accent to the production’s main 17’ projection screen. The PixelFLEX panels run a variety of content throughout the show, including a series of flags from various countries, to provide different looks and feels on stage. For organizers of Student Life’s Be Last Conference, ease of use and set-up are the primary benefits to using the PixelFLEX solution.
“They are extremely easy to use,” said Jake Brantley, producer for Student Life. “Being able to change the look and feel of our stage at the drop of a hat is invaluable. When we have more of an upbeat sound on stage, we can use fast moving graphics and bright colors to add energy. If we’re trying to create a more serious tone, we can add darker blues and slower motion graphics without having to change the backdrops. All of this can be done simply with a click of a button.”
Flexible in all directions, PixelFLEX LED Curtains are able to bend and shape around structures for a more creative display effect and can be stored in a single road case to simplify shipping. This flexibility is critical to Brantley and his team during the Be Last Conference – both during and after the performance.
“With the way we’re using the LED panels on stage, having the ability to shape the panels as we need to is crucial – in one or two places we use them to create a nice arch or 90 degree bend around a corner,” Brantley stated. “On top of that, it only takes two people to load the panels in and out before and after the show, which means we can be done with set up and tear down more quickly. Finally, the fact that you can fold and store the panels in travel cases is a tremendous cost saver for a small tour like ours.”
Videos and images can be sent to PixelFLEX’s screens using any computer with a DVI-D connection. Each typical screen panel is approximately 8×4, but modifications can be made easily to meet specific needs of the consumer – panels can be attached together with PixelFLEX’s proprietary quicklock system.
“PixelFLEX’s panels give us a ton of versatility with regard to the custom content we’re able to incorporate into the tour,” Brantley remarked. “We have an unlimited amount of options as to what our stage can look like and that is cool.”
