Display technology has rapidly evolved over the past decade. Three prominent types – OLED, LCD, and plasma, have specific strengths and weaknesses that determine their suitability for various applications. As an innovator in mall kiosk solutions, HeyKD utilizes cutting-edge display technology to create immersive retail experiences that attract and engage customers.

OLED Displays – The Pinnacle of Picture Quality

OLED (Organic Light Emitting Diode) displays have become renowned for their ability to produce true blacks and life-like picture quality unrivaled by any other display technology currently available. This is made possible as each pixel in an OLED display emits its own light. As a result, when a pixel is turned off, it produces a true black. This gives OLED displays an effectively infinite contrast ratio and allows them to render much deeper blacks than LCD or plasma displays.

The self-emitting nature of OLED pixels also ensures wider viewing angles with consistent color accuracy and image quality across the entire screen. Modern OLED panels have also overcome early challenges like high input lag, making them well-suited for gaming thanks to features like Game Mode and pixel refreshers that prevent permanent image retention.

With major manufacturers like LG and Sony continually improving OLED technology and reducing prices, OLED displays are becoming accessible for more applications where visual quality is paramount, including digital signage and kiosks.

LCD (Liquid Crystal Display) 

LCD (Liquid Crystal Display) technology has become ubiquitous largely due to its cost-effectiveness and ability to be produced in thin, lightweight form factors. Modern LCD panels are backlit using LEDs rather than traditional cold cathode fluorescent lamps (CCFL), providing increased brightness, better contrast, and reduced power consumption.

Additionally, LCD panels come in different types such as IPS, VA, and TN, each with their relative strengths and weaknesses in areas like viewing angles, color consistency, native contrast ratios, and response times. IPS panels offer the best viewing angles at the expense of contrast while TN panels have quicker response times. VA panels provide a balance between viewing angles, color reproduction, and response time.


Modern LCD technology has improved drastically over early iterations, with advancements like full array local dimming (FALD), quantum dots for wider color gamuts, and mini/micro LED backlights that allow for thinner displays with higher peak brightness and better power efficiency. As a result, LCD remains the dominant display technology for most applications where cost is a bigger concern than achieving the pinnacle of visual quality.

Plasma Displays – A Dying Technology

Plasma displays were once lauded for their incredible picture quality potential and rapid response times that made them well-suited for fast-motion content like sports. This was achieved by exciting phosphor cells using electrical charges to emit light.

However, plasma technology had some inherent weaknesses like increased power consumption, heat generation, reflective display surfaces, and permanent image burn-in that proved difficult to overcome. As LCD and eventually OLED matured with fewer drawbacks, consumer and commercial demand for plasma displays rapidly declined. As a result, plasma TV and panel production has been completely discontinued, effectively ending the technology’s relevance.

Enhancing Image Quality – Quantum Dots, Local Dimming & 4K HDR

Quantum Dots & QLED

Quantum dot technology enhances LCD image quality by providing increased brightness, a wider color gamut, better color accuracy and energy efficiency compared to traditional LED-backlit LCD panelsSamsung leverages this in their QLED TVs to great effect.

They have also introduced QD-OLED technology that infuses the benefits of quantum dots into self-emitting OLED pixels to increase peak brightness beyond what standard OLED panels can achieve while retaining the deep blacks and pixel-level control of OLED. As quantum dot technology continues maturing, it will become viable for more display applications where color accuracy is vital.

Local Dimming

Local dimming allows LED-backlit LCD displays to selectively dim or boost the brightness of specific areas of the screen to optimize contrast. This helps replicate the deep blacks of OLED panels. For best results that minimize blooming around bright objects, full-array local dimming (FALD) is recommended over edge-lit options.

4K Ultra HD and HDR

4K Ultra HD (also known as 2160p) provides a significant resolution bump over standard 1080p, with over 8 million pixels for increased clarity and sharpness. This allows more detailed and immersive visuals. Pairing 4K resolution with HDR (High Dynamic Range) enhances color depth, brightness, and contrast for vibrant, true-to-life picture quality. Most high-end OLED and LED LCD panels support these features, delivering a mesmerizing viewing experience.

Applications of Display Technology in Mall Kiosks

As an innovator in providing customized mall kiosk solutions globally, HeyKD utilizes cutting-edge display technology to create engaging, informative and entertaining retail experiences. Our kiosks employ large format displays to attract customer attention with vivid motion graphics and life-like visuals.

OLED and high-end LCDs with features like 4K Ultra HD, HDR and local dimming allow our kiosks to render bright, vivid colors and deep contrasts even in brightly lit mall environments. Their wide viewing angles also ensure engagement from broad sightlines.

For gaming and simulation kiosks, high refresh rate OLED panels provide smooth, tear-free visuals and rapid response for interactivity while QD-OLED technology offers increased peak brightness.

Cost-effective and energy efficient LCD solutions allow us flexibility in creating affordable kiosks without compromising too much on visual impact. Their slimmer profiles also help minimize kiosk footprint.

Curved display configurations are also commonly employed for enhanced immersion. Paired with responsive touch interfaces and motion tracking, our cutting edge kiosks effectively engage customers while showcasing products and services.

We also leverage display technology to create striking merchandising kiosks that encourage retail purchases and boost sales for our clients. This includes digital signage for pricing, promotions and advertisements displayed on LCD or OLED panels placed strategically to capture customer attention.

Our commitment to using the latest display innovations enhances our kiosk solution portfolio and allows us to better serve clients globally. As display technology continues advancing, we look forward to harnessing those improvements to take mall kiosk interactivity to new heights.

Conclusion – Choosing the Right Display Technology

Determining the most suitable display technology for kiosks and other applications requires balancing visual quality, cost, form factor, brightness requirements and usage scenarios.

OLED and QD-OLED displays are ideal for situations where true blacks, wide viewing angles and exceptional picture quality are necessities, such as digital signage or gaming. However, their premium pricing makes LCD technology a more practical choice for general retail and interactive kiosks.

Among LCD variantsIPS panels make the most sense for kiosks due to their color consistency from wide angles – essential for engaging passing shoppers. VA panels can be leveraged where deeper blacks are preferred for spotlighting products. For video walls, TN panels provide a good balance of response times and viewing angles.

High brightness, commercial-grade LCDs with HDR, local dimming and 4K resolution allow visually stunning kiosk implementations at reasonable costs. Mini LED backlighting produces slimmer profiles while improving contrast and peak brightness compared to traditional LED edge-lit LCDs.

Continued innovations like microLED with self-emitting pixels could potentially unify the benefits of OLED and LCD. However, OLED and high-end LCD technology available today can already enable exceptionally vibrant, vivid and immersive retail kiosk experiences bound to attract customers and boost sales.
