If you‘re looking to upgrade to a new high-end TV, you‘re likely considering two display technologies – OLED and QD-OLED. Both deliver amazing picture quality and performance. But what exactly sets them apart?

In this comprehensive guide, I‘ll explain the crucial differences between OLED and QD-OLED televisions. I‘ll go over how they each work, compare picture quality, viewing experience, pricing, and more – so you can determine which is better for your needs. Let‘s dive in!

Tracing the Development History of OLED Displays

To start, it helps to understand where OLED technology originated. OLED stands for "organic light-emitting diode." Rather than requiring a backlight like LCD displays, OLED pixels directly emit their own colored light.

This enables revolutionary picture performance. But it took years to make OLED feasible for television.

1960s-1990s – Early OLED Research

  • OLED research began in the 1960s, with pioneering work done at Eastman Kodak on power-efficient organic electroluminescent materials. This laid the groundwork for future OLED development.

  • Throughout the 1970s to 1990s, efforts continued to refine OLED materials and device architectures, yielding improvements in luminance, efficiency and lifetime.

Early 2000s – First Commercial OLED Products

  • In the early 2000s, OLED technology progressed to the point where commercial products could be manufactured:
    • In 2002, TDK released the first OLED display in a commercial product – the VP4 electronic dictionary.
    • Other portable devices with small OLED screens followed from Sony, Samsung, Motorola and others.
    • But the manufacturing challenges of large OLED panels delayed OLED TV development.

2008 – OLED TVs Arrive

  • Finally, in 2008, the first OLED TV entered the consumer market:
    • LG introduced a 15" OLED TV priced at $2500, with only 200 produced.
    • Reviews were amazed by OLED‘s:
      • Perfect black levels and high contrast
      • Vibrant colors
      • Wide viewing angles
      • Stylish, razor-thin form factor
    • But mainstream adoption was hampered by OLED‘s high prices and small screen sizes at the time.

2010s – OLED TV Technology Maturing

  • During the 2010s, LG invested heavily in OLED manufacturing capabilities. This expanded OLED TV screen sizes and reduced prices:
    • In 2013, LG launched the first 55" OLED TV.
    • By 2016, their OLED TV lineup extended to 65" and 77" models.
    • Prices dropped from $10,000+ for early 55" models to under $2000 by the mid 2010s.
  • Other brands like Sony, Philips and Panasonic also began offering OLED TV models, further boosting OLED‘s profile.

After major investments and refinements, OLED TVs by the late 2010s delivered outstanding picture quality at sizes and prices accessible for high-end consumer TV buyers. Next came the emergence of QD-OLED…

The Road to QD-OLED TV Commercialization

While LG pioneered OLED TVs, Samsung spearheaded development of QD-OLED displays:

Early 2000s – Quantum Dot Research

  • Quantum dots are semiconductor nanocrystals that produce pure colored light. Research into their usage for displays began in the early 2000s.
  • Key advantages were identified, like high color purity and tunable emission wavelengths. This made quantum dots promising for enhancing LCD TVs.

2010s – First Quantum Dot LCD TVs

  • In 2015, LG released the first QD LCD TV using quantum dot film in the backlight – the EF9500.
  • But quantum dot LCD backlights had limitations, unable to match OLED contrast and black levels.

2010s – Samsung Develops QD-OLED Concept

  • Recognizing this limitation, Samsung researched combining quantum dots directly with self-emissive OLED tech, rather than LCD:
    • In 2019, they unveiled the first QD-OLED prototype.
    • It used blue OLED pixels with quantum dots creating the red and green, boosting brightness and efficiency.
  • This hybrid quantum dot OLED approach aimed to merge the benefits of both technologies.

2022 – First QD-OLED TVs Launch

  • After years of development, the first consumer QD-OLED TVs arrived in early 2022:
    • Samsung launched their S95B series QD-OLED TVs in March 2022, in 55" and 65" sizes.
    • They touted exceptional color, brightness, and contrast from this new display technology.
  • The age of QD-OLED TVs had finally come, presenting an alternative high-end option to standard OLED.

QD-OLED leverages the self-emissive capabilities of OLED at higher brightness levels enabled by quantum dots – a best-of-both-worlds combination. But how exactly does QD-OLED stack up against traditional OLED? Let‘s compare.

QD-OLED vs. OLED: Side-by-Side Technology Comparison

While both utilize OLED pixels, QD-OLED and conventional RGB OLED panels have distinct designs:

Display Architecture QD-OLED OLED
Pixel Structure Blue OLED + Quantum Dot Layer RGB OLED
Blue OLED Yes Yes
Red & Green OLED No Yes
Quantum Dots Yes No
Color Filters No Yes
Blue Light Usage High Efficiency Medium Efficiency

Key Differences:

  • In QD-OLED, blue OLED light passes through a quantum dot layer. The quantum dots convert some blue to pure red and green.

  • OLED uses dedicated red, green and blue OLED materials to emit all colors directly. Color filters enhance the palette.

  • QD-OLED creates red/green through color conversion, leading to higher light efficiency and intensity compared to OLED.

So while both leverage OLED pixels, QD-OLED‘s quantum dot component makes its underlying structure fundamentally distinct from conventional RGB OLED panels.

This difference in light generation translates into divergent display performance…

QD-OLED vs. OLED TV Picture Quality Showdown

On paper the technology varies. But in real-world usage, picture quality is what matters. So how do QD-OLED and OLED TVs compare for visual performance?

  • Here, they‘re equal. Both use self-emitting OLED pixels that can turn off completely to produce infinite blacks and contrast ratios.

  • Scenes with bright highlights against dark backgrounds will look stunning regardless of your OLED or QD-OLED choice.

Peak Brightness

  • QD-OLED wins. Quantum dots give QD-OLED TVs 60-100% higher peak brightness compared to traditional OLED.

  • QD-OLED can reach 1500-2000 nits for searing highlights. OLED tops out around 800 nits.

  • So HDR content can deliver more spectacular bright visuals on QD-OLED.

Color Volume

  • Thanks to higher luminance, QD-OLED also outperforms on color volume – the combination of color gamut and brightness.

  • QD-OLED produces 80-90% of the expansive BT.2020 color space. OLED lags at 70-80% BT.2020.

  • This wider palette at higher brightness makes QD-OLED the winner for vivid, realistic colors.

Viewing Angles

  • Both offer nearly 180-degree off-angle viewing without color shifting or contrast loss.

  • QD-OLED initially struggled a bit here but has been dramatically improved through optical film stack enhancements.

  • So excellent viewing angles are now a tie between OLED and QD-OLED – perfect for wide seating arrangements.

By leveraging quantum dots, QD-OLED TVs outpace OLED in brightness and color while matching their perfect contrast and viewing angles. But what about the ultimate criteria – the viewing experience?
