Common Applications of QLED Displays
How to Choose a Quantum LED Display
QLED Compared to Other Displays
Continuous innovation is important in any technology field, and the display sector is no different. There are many key factors to consider when choosing the right display for you or your business, but one of the most important is the quality of the visuals. Over time, display technologies have evolved to produce images that are as realistic as possible in depicting the world as we see it. One of the emerging technologies that has been instrumental in creating high-quality displays is Quantum Dot Light Emitting Diode (QLED) technology. Read on to find out what differentiates this technology from other flat-panel displays.
Quantum Dot LED technology was developed by Samsung as early as 2020. The technology was intended to improve upon existing LED displays. Samsung discovered that when Quantum Dots are illuminated, they emit light at a specific wavelength. This led to research on how these dots could be illuminated to display the three primary colors (red, blue, and green). In 2020, Samsung made a breakthrough by developing blue Quantum LED technology. Since then, there has been continuous advancement in the technology, leading to the production of displays with deeper images and better quality.
To understand how QLED works, it’s important to understand the technology behind it: Quantum Dots. A Quantum Dot is an artificial nanoparticle with semiconductor properties. They come in a variety of sizes, ranging from two to 10 nanometers. The size of these particles dictates the wavelength each particle emits, and thus the color.
Quantum Dots are usually created on a film sheet and then sandwiched behind an LED backlight that illuminates an LCD. This way, the technology enables the LCD display to show a wider range of more saturated colors that would otherwise be impossible.
The primary characteristic that makes Quantum LED a preferred display is its ability to produce bright images while maintaining good color accuracy, even in areas with plenty of natural light. This makes the technology ideal for either indoor or outdoor use, especially in areas where lighting conditions vary significantly.
Their versatility and superior image quality have made Quantum LED the preferred display in different sectors. One of its most notable applications is in creating digital signage. With advertising becoming increasingly important, creating a high-quality sign has become essential for effective information dissemination. Quantum LED displays produce high-quality signs with vibrant colors and sharp contrast, making it easy to convey the message to current and future customers. The crisp display of this technology makes advertisements more eye-catching, capturing more attention.
Another major application of this technology has been in the creation of video walls. In corporate events, entertainment venues, and control rooms, Quantum LED technology is used to create an immersive and seamless visual experience. The wide range of colors displayed by Quantum LED and its high brightness levels ensure that each detail is accurately represented, regardless of the lighting conditions.
In large businesses and public spaces like shopping malls, stadiums, and airports, QLED technology has been used to create reliable and durable displays that are well-suited for continuous operation.
There are several factors to consider when choosing a Quantum LED display to ensure you get value for your money. First, consider the intended use of the display. Understanding what the display will be used for is important in determining the size and specifications required.
Brightness level is another crucial factor. Depending on the environment, you may require a display with different nit levels. For outdoor use or in a well-lit environment, select a display with high nit levels. Display placement could also determine the model you choose.
Lastly, consider the resolution. Depending on your needs, you can choose either a 4K display or a 1080p display. Higher resolution displays are essential in areas where detailed images are crucial, such as professional presentations or high-end retail shops.
As the name suggests, the main difference between the two displays is the quantum layer in Quantum Dot LED displays. The additional layer allows Quantum LED displays to have a wider color gamut and better brightness levels compared to LED, resulting in enhanced visual performance and more vibrant images.
OLED is one of the most advanced display technologies often compared to Quantum Dot LED. The key difference is that Quantum LED uses a backlight for illumination, while OLED uses organic compounds to emit light for each individual pixel. As a result, OLEDs have an infinite contrast ratio and deeper blacks. However, QLEDs offer higher brightness levels and color volume, making them more suitable for outdoor environments.
Many people believe that high-resolution displays are effective in bright conditions regardless of the technology, but this is not entirely true. 4K resolutions produce stunning, detailed images, but the brightness of those images will depend on the underlying technology. 4K Quantum Dot LED displays offer images with more vibrant colors than other displays of the same resolution.
LCDs are by far the most widely used display technology across various industries due to their affordability. However, Quantum Dot LED outperforms LCD in brightness, color accuracy, and viewing angles, making the images more vivid and lifelike. The Quantum Dot layer ensures a more immersive viewing experience compared to traditional LCDs.
Quantum LED technology is continuously transforming the visual experience, and not just for large-screen TVs. Its application in digital signage, video walls, and large public displays shows the potential of this technology to revolutionize the display sector with better and more vivid images.
