LCD, LED, OLED—what’s the difference?

In an age when online merchants are offering so much, brick-and-mortar businesses are looking for exciting ways to communicate their value proposition clearly and effectively. Their products and services need to get noticed, and their brand equity must continually be reinforced to maintain customer loyalty. And in order to increase in-store traffic, a business needs to stand out more than ever.

When used strategically digital signage can be a strong differentiator, and now there’s a choice of display options to suit virtually any business. Let’s look at the technologies.

LCD (Liquid Crystal Display) panels offer bright, high-resolution images. LCDs require a light source to illuminate the screen pixels, and the first-generation displays used CCFL (Cold Cathode Fluorescent Lamps). CCFL backlights did a fine job but had a few drawbacks—their physical size required the overall panels to be thick, they used a lot of electricity, and they had a limited life expectancy.

In the next generation, LED (Light Emitting Diode) technology solved the challenges associated with CCFL. Using a LED light source to illuminate the pixels, the display panel could be thinner and use less power. LEDs also have a much longer life expectancy. NOTE: While commonly referred to as LED displays, these displays are actually LCDs that use a LED light source.

LCDs are great for picture quality, especially those with IPS (In-Plane Switching) screen technology. They are available in Full HD (1080p) or Ultra HD (4K) resolution. Full HD is beautifully crisp and sharp, and 4K is amazing for detail, ensuring that every element on the screen pops. 4K also makes it possible for customers to be closer to a big screen without noticing the pixels that make up the image.

Direct View LED displays are something different. These displays eliminate the LCD panel and use a surface array of LEDs as the actual display pixels. Direct View LED displays feature outstanding contrast, vibrant colors and brightness levels several times that of LCDs. They can also be made in virtually any size, including very large sizes of 100 feet or more, making them the perfect choice for outdoor spaces such as sports arenas.

Fast forward to now. Thanks to LG, businesses can display their best on OLED. OLED displays incorporate the most advanced display technologies, and yield an unprecedented combination of picture quality and installation flexibility. OLED (Organic Light Emitting Diode) displays eliminate the need for a separate light source—each pixel emits its own light, and can turn itself off, resulting in a more exact control of image quality.

OLED displays yield incredibly accurate color, perfect black and infinite contrast. They also provide wide viewing angles, a major advantage in larger environments. Fast action scenes are crisp, clear and free from blur, thanks to OLED’s extremely fast response time. It’s the same unrivaled picture quality that consumers recognize from LG’s state-of-the-art OLED televisions

LG’s amazing OLED displays are available in sleek, pencil-thin, open-framed designs that can also be curved and customized into convex or concave forms. Dual-sided OLED displays show images on the front and back of the panel, with the ability to swap and mirror content on either side. In the world of commercial displays, nothing else compares.

The effective use of digital displays can create the differentiation businesses need to better engage their customers, enhance presentations or provide valuable information in attention-grabbing ways.
