The Backstories Behind OLED and LED Displays
Before evaluating OLED vs. LED display technologies on key features, let’s briefly cover what they are and where they originated…
A Quick History of OLED Displays
OLED stands for “organic light-emitting diode” – a reference to the carbon-based compounds that light up when electricity passes through them. The first observations of this electroluminescence in organic materials occurred back in the 1950s.
But it wasn’t until 1987 when researchers Ching W. Tang and Steven Van Slyke at Eastman Kodak built the first viable OLED device – a two-layer demonstrator with brightness levels sufficient for practical applications. This kicked off over a decade of advancement in materials, manufacturing techniques, and commercialization.
Fast forward to the early 2000s when major display makers like Toshiba, Sony and LG introduced the first consumer OLED screens and TVs. Their brilliant colors and inky blacks quickly set a new bar for video quality. Today, OLED usage continues increasing thanks to falling production costs and streamlined fabrication.
The Inception of LED Displays
Unlike OLED’s organic compounds, LED stands for “light-emitting diode”. This refers to a semiconductor component that releases photons when current passes through.
The first LED traces back to British experimenter Captain Henry Joseph Round who observed initial electroluminescence in silicon carbide and patented the first LED in 1907.
But it wasn’t until the 1960s when practical visible-spectrum LED displays entered the consumer electronics scene. They quickly gained popularity for their efficient illumination and durability. Continued development eventually enabled full-color LED screens through the 1990s and 2000s.
Today, LED-backlit LCD displays dominate applications like smartphone screens, computer monitors and affordable television options – especially as manufacturing costs drop. However, OLED retains a stronghold in high-end devices where visual performance takes priority.
How Do OLED and LED Displays Work?
Now that we’ve covered the origins of both display technologies, let’s contrast how they operate at a basic level:
OLED Display Composition and Function
OLED displays utilize thin films of organic carbon-based compounds that light up in reaction to electrical currents. These OLED materials are situated between two conductors – a positively charged anode and negatively charged cathode.
When voltage gets applied across the conductors, electrons migrate from the cathode into the organic layer where they combine with electron holes. This electronic excitement causes the organic particles to shed energy as photons – creating visible light.
So in summary: electricity flows into OLED panels → organic films react by emitting light → no backlight required.
Benefits of OLED Displays:
- Self-illuminating pixels switch off completely for true blacks
- Excellent color accuracy and contrast
- Fast response times for smooth motion
- Wide viewing angles without distortion
- Thin/flexible form factors
Downsides of OLED Displays:
- More prone to permanent burn-in vs. LED
- Peak brightness still trails best LED displays
- Generally more expensive than LED
LED Display Architecture
LED stands for “light-emitting diode” – basically a semiconductor chip that generates photons from current flow. An LED display uses a panel of these LED chips to provide background illumination – AKA backlighting.
This backlight shines through a layer of liquid crystals and color filters to produce the pixels that make up the screen’s overall image. Think of it as the LEDs serving as a replacing fluorescent bulbs behind the LCD matrix.
So in summary: LEDs generate backlight → liquid crystals manipulate light → forms image you see.
Benefits of LED Displays:
- Excellent peak brightness with HDR content
- Durable and energy efficient
- No risk of permanent burn in
- Lower manufacturing costs than OLED
Downsides of LED Displays
- Blacks appear gray due to ever-present backlight
- Light bleed around bright objects
- Colors wash out at wider viewing angles
| Display Attribute | OLED Display Capability | LED Display Capability |

| Peak Luminance | Up to ~800 nits | Up to ~2000 nits |
| Average Lifespan | 30,000 hours | 60,000 hours |
| Refresh Rate | Up to 240Hz | Up to 240Hz |
| Response Time | Under 1ms | 5-8ms |
| Peak Efficiency | Up to 100 lm/W | Up to 270 lm/W |
| Commercial Availability | 13-100 inch panels | 4-1,000+ inch |
Comparing Picture Quality: OLED vs. LED
Given the fundamentally different methods by which OLED and LED displays generate light, how do they compare when it comes to real-world video performance? Let‘s analyze the critical metrics:
Contrast and Black Level
Contrast ratio quantifies a display‘s ability to delineate light and dark areas – expressed numerically in a X:1 format. The higher the ratio, the more nuanced tones are reproduced. Deep blacks are crucial for realistic images.
OLED panels achieve essentially infinite native contrast since pixels produce their own light and can deactivate completely. This equates to rich, inky blacks. LED backlighting prevents full pixel deactivation so blacks appear more gray by comparison. Those deeper OLED blacks translate into a more refined, lifelike picture overall.
Winner: OLED
Peak Brightness
When it comes to showcasing the brightest elements in video content like specular highlights, outdoor scenes and HDR material, today’s highest-end LED televisions maintain an advantage over comparably sized OLED models – hitting upwards of 2000 nits. However, modern OLED TVs match or exceed the 500-600 nit peak brightness levels required for pleasing high dynamic range content.
Ultimately, side-by-side comparisons confirm that OLED’s pixels dimming completely to zero nits balances out this LED brightness advantage in most real-world viewing. But for exceptionally bright viewing environments like sunlit rooms, LED remains the better option.
Winner: LED
Color Accuracy
The ability to faithfully reproduce the full range of hues comprising video content comes down to color volume and gamut capabilities.
OLED panels curve along the horseshoe area of standard chromaticity graphs thanks to their per-pixel light emission control. LEDs depend on filtering and doping backlight output to achieve their color range. Both satisfy common video color space requirements like DCI-P3 and Rec. 2020.
So when comparing color accuracy, gamut coverage and volume are quite comparable. However OLED again excels due to its pixel-perfect control over hue and intensity. Vibrant reds, lush greens and bright blues simply appear more striking thanks to OLED‘s contrast.
Winner: OLED
Viewing Angle
For screens that need to maintain color fidelity and brightness when viewed from off angles – like multiple television viewers or collaboration video conferencing – viewing angles become vital.
OLED panels hold a significant edge here as well thanks to pixels directly emitting their own colored light. Colors remain consistent with minimal dimming even when viewed from severe horizontal or vertical angles on OLED screens.
Whereas LED backlighting projecting through LCD crystals tends to shift both brightness and accuracy considerably when viewed slightly off axis. So OLED is the superior option for wide viewing needs.
Winner: OLED
Motion Handling
The ability to cleanly resolve fast movement without distraction artifacts comes down to refresh rate and pixel response time.
The latest OLED and LED televisions now support up to 120Hz effective refresh rates thanks to backlight strobing, frame insertion and native panel speeds. This results in clear rendering of quick action scenes in video footage or gaming visuals.
And when considering pixel response – the time required to transition from one color/brightness to the next – OLED panels are inherently faster thanks to directly emitting light rather than waiting for liquid crystals to shift. But even LED response times have now dropped to levels sufficient for the majority of video applications outsideperhaps extremely competitive esports gaming.
Winner: Draw
