HDR: The Illuminating Introduction
At its core, HDR is all about expanding the range between the brightest and darkest parts of an image, giving you richer colors, more detail, and an overall jaw-dropping visual experience.
Minimum Requirements
To join the HDR club, a display needs to meet certain minimum standards. We're talking about a minimum peak brightness of 1000 nits (that's really bright), a maximum black level of 0.05 nits (super dark), and a minimum contrast ratio of 20000:1 (high contrast). These numbers set the stage for the HDR spectacle.
Most edge-lit LED displays use global dimming, which is not capable of displaying the contrast level required in the HDR videos. As a result, most of the HDR-compatible displays you'll encounter would be OLED or AMOLED types.
As you might have guessed, the video source and the medium that plays the video (such as your disk-player or media streamer) must also support the HDR format; an HDR display won't automatically render everything thrown at it in HDR.
SDR vs HDR: The Showdown of Smartphone Display Tech
Before the HDR came about, there was SDR (Standard Dynamic Range). It was named that after HDR was conceived. Let's break down the nitty-gritty details of the epic battle between SDR and HDR, so you'll never look at your screen the same way again!
SDR: The Silent Hero
First, let's give a shout-out to SDR. It is like that reliable friend who's always there but doesn't seek the limelight. It's been around since the dawn of television, offering decent picture quality. But, compared to HDR, it's like the black and white movie in a world of Technicolor.
HDR: The Visual Maestro
On the other side of the ring, we have HDR, the champion of the present article. HDR is like the rockstar who rolled into town and stole the show. It cranks up the brightness, sharpens the details, and brings colors to life in a way that makes SDR look like a grayscale comic strip.
The Battle of Brightness
One of the key differences between SDR and HDR is brightness. SDR typically operates with a peak brightness of around 100 to 300 nits (and a black level of about 0.1 nit), which is like a flashlight in a dark alley. HDR, on the other hand, can hit peak brightness levels of up to a whopping 10000 nits. That's like turning on stadium floodlights during a nighttime football game. HDR practically bathes your eyes in radiance!
The Contrast Clash
Contrast is another battlefield where SDR and HDR duke it out. SDR has a modest contrast ratio, usually around 1000:1. It's like trying to spot a chameleon on a green leaf - not easy. Meanwhile, HDR boasts contrast ratios of 20000:1 or more, making it as clear as day to spot that camouflaged critter.
The Color Carnival
When it comes to color, SDR often sticks to the basic crayon box, offering 8-bit (per channel - each of R, G, and B) color depth. HDR, on the other hand, is an artist with a 10-bit or even 12-bit palette. It's like comparing a child's drawing to a masterpiece by da Vinci. HDR paints a richer, more nuanced visual canvas.
Dynamic Drama
One more thing to note: HDR often supports dynamic metadata, adjusting the picture scene by scene for optimal quality. SDR, unfortunately, doesn't have that level of adaptability. It's like HDR is a gourmet chef, while SDR is following a recipe book to the letter.
The Winner Takes All? In the battle of SDR vs HDR on smartphone displays, HDR emerges as the clear victor. It's the superhero of visual technology, giving you brighter, sharper, and more vibrant images. SDR, while a trusty companion of the yesteryear, just can't compete with the dazzling spectacle of HDR.

Before proceeding to describe the various HDR formats, let's take a behind-the-scenes look at the "metadata" used by them, and see why it's crucial and how it comes in two flavors - static and dynamic.
HDR Metadata Demystified: Static vs Dynamic Metadata in HDR Formats
Suppose you're a director making a blockbuster movie, and you want to ensure that every scene looks its absolute best on different screens. That's where metadata steps into the spotlight in the world of HDR formats like HDR10, HDR10+, and Dolby Vision.
Metadata: The Director's Notes for Your Display
First things first, what's metadata, and why do we need it? Metadata is like the director's notes for your display. It's a set of instructions that tells your TV or smartphone screen how to present the content optimally. Without metadata, it's like asking an actor to perform without a script - chaos would ensue!
Static Metadata
Let's start with static metadata, which is like a one-size-fits-all instruction manual. When you start watching a movie in HDR10, the metadata sets the display's capabilities right at the beginning of the content. It's like the director handing out the same script to all the actors and hoping it works for every scene.
Static metadata in HDR10 defines the peak brightness, color space, and other parameters that the entire movie will follow. While it's a good baseline, it does not adapt to individual scenes, and that can sometimes lead to scenes looking less than optimal.
Dynamic Metadata
Dynamic metadata is like having a director on set who can adjust the script for each scene. The metadata changes scene by scene (or even frame by frame), ensuring that your display shows each part of the movie at its best. It is used on the displays that lack the capability to render the HDR video in its fullest intended glory.
Imagine a movie where some scenes take place in a dimly lit cave and others in a sun-soaked desert. Dynamic metadata is like the director tweaking the lighting and set design for each location. It's a game-changer for visual quality on HDR-limited displays.
The Metadata Magic: In the world of HDR formats, metadata is the secret sauce that ensures you get the best visual experience possible. Static metadata, as seen in HDR10, sets the stage but lacks adaptability. Dynamic metadata, as found in HDR10+ and Dolby Vision, takes customization to a whole new level, making sure every scene shines.
Now, let's get down to the nitty-gritty of the HDR flavors.
HDR10: The Bold and The Beautiful
HDR10, an open HDR standard announced on the 27th August, 2015, is often hailed as the baseline for HDR, and delivers stunning visuals. It supports 10-bit color depth (for each of R, G, and B channels) and a brightness between 1000 and 10000 nits, though the HDR10 content is typically mastered with a maximum brightness of 4000 nits (blindingly bright).

HDR10: Static Metadata Star: HDR10 supports static metadata, which means that the display's capabilities are defined at the beginning of the content, and they don't change as the content plays. It's like a chef telling you exactly what ingredients are in your meal before you take your first bite.
Some smartphones that rock HDR10 include the Samsung Galaxy S21 and the Google Pixel 5. They're like the rockstars of the smartphone world, delivering vibrant, eye-popping visuals.
HDR10+: The Dynamic Dynamo
Announced on the 20th April, 2017 by Samsung and Amazon Video, HDR10+ is the HDR standard that takes things up a notch (or ten). It's like HDR10 but with a twist - dynamic metadata (developed by Samsung), which means the display can adapt and optimize the picture scene by scene (or frame by frame). Imagine a personal stylist who tweaks your outfit based on your location and mood - that's dynamic metadata! Additionally, it can have color depth of 10 bit or more (for each of the channels R, G, and B). It supports resolutions up to 8K.
Unlike Dolby Vision, HDR10+ is free to use for content creators; it only has an annual license of a maximum of USD 10000 for some manufacturers. This can be a factor pushing it to the top in its battle with Dolby Vision.
Smartphones like the OnePlus 9 Pro and the Xiaomi Mi 11 are flaunting HDR10+ support. They're like the cool kids in school who always have the latest trends.
HDR10+ Adaptive
This is an enhanced version of HDR10+ that adjusts the content according to the ambient light; that is, it instructs the display to set its properties, such as brightness and contrast, according to the light that it detects around the display. So if someone opens the door of the room while you're watching the TV, the TV will adjust its display settings automatically to compensate for the increased ambient brightness.
Dolby Vision: The Hollywood Standard
When it comes to HDR, Dolby Vision is the Hollywood A-lister. This technology, introduced in the year 2014, boasts 10-bit or 12-bit color depth (for each of the channels R, G, and B), which is like having a palette of a gazillion colors at your disposal. It supports a peak brightness of up to 10000 nits (hello, sunshine), black level of at most 0.005 nits, contrast ratio of 200000:1, and a maximum resolution of 8K.
Phones like the iPhone 13 Pro and the LG G8 ThinQ are in the Dolby Vision club. They're like the VIPs at the HDR party, offering cinematic visuals in the palm of your hand.
Dolby Vision: Dynamic Metadata Extravaganza
Like HDR10+, Dolby Vision also uses dynamic metadata, and it also sports 12-bit color depth. It's like the director working with a full spectrum of colors, creating a masterpiece with every frame.
Dolby Vision's dynamic metadata is like having a director who's not just on set but is fine-tuning every frame individually. It adapts to the specific capabilities of your display. It's the pinnacle of HDR quality, offering a visual feast like no other.

3D Lightfield Display
A 3D lightfield display is an advanced type of display technology that captures and projects light fields, enabling the presentation of images in three dimensions without the need for special eyewear. Unlike traditional 3D displays, which require glasses to filter separate images to each eye, a lightfield display recreates the way light interacts with objects in the real world, making the 3D experience more natural and immersive.
How Does a 3D Lightfield Display Work?
A 3D lightfield display works by emitting light rays at different angles to produce a 3D image. This involves complex optics and display layers that can direct light in such a way that each eye perceives different perspectives of the same image, thus creating the illusion of depth. Here's a simplified breakdown of how it operates:
- Multi-View Projection: The display generates multiple views of the same scene from slightly different angles. Each view corresponds to what one would see from that specific angle in real life.
- Directional Light Emission: Special optics, such as lenticular lenses or parallax barriers, guide the emitted light so that each view is directed towards the correct position relative to the viewer's eyes.
- Eye Tracking (Optional): Some advanced systems incorporate eye-tracking technology to dynamically adjust the angle of light projection, ensuring the best possible 3D effect as the viewer moves.
So, how does a display show 3D content without special eyewear? Well, displays employing technologies like 3D lightfield projection or parallax barriers achieve eyewear-free 3D viewing by controlling the direction of light emission. By carefully directing light to each eye, these displays ensure that each eye receives a slightly different image, creating the perception of depth.
This mimics natural binocular vision, where each eye sees the world from a slightly different angle, allowing our brain to process the images into a single 3D view.
Applications and Uses of 3D Lightfield Display
3D lightfield displays have a wide range of applications, including:
- Entertainment: Enhancing gaming and movie experiences with immersive 3D visuals.

The Neovision 3D Anytime display technology is a specific implementation of the 3D lightfield technology that incorporates stereoscopic eye-tracking for a dynamic and interactive 3D viewing experience. Essentially, it is a specialized version of the broader 3D lightfield display technology, tailored to enhance usability and comfort.
In simple terms, here is how the Neovision 3D Anytime display technology works:
- Stereoscopic Eye-Tracking: Neovision 3D Anytime relies on stereoscopic eye-tracking technology to deliver a 3D experience. It tracks the user's eye movements and adjusts the display accordingly to ensure the 3D effect is always optimal.
- Simulated Depth: Similar to the Nintendo 3DS, Neovision 3D Anytime projects images with simulated depth, creating a convincing 3D effect without the need for special glasses. This is achieved by projecting slightly different images to each eye, tricking the brain into perceiving depth.
- Viewing Angle: The technology supports a certain viewing angle (e.g., 60°), which means you can move your head within this range and still maintain the 3D effect. This flexibility makes it more comfortable and practical for extended viewing sessions.
In summary, whether you're watching videos or playing games, a display supporting the Neovision 3D Anytime provides an outstanding, eyewear-free 3D visual experience.
AI-Driven Real-Time 2D-to-3D Conversion
AI-driven real-time 2D-to-3D conversion is a technology that uses artificial intelligence (AI) algorithms to transform 2D content into 3D in real time. This means that videos, images, and other media can be viewed in 3D without having been originally designed for that format.
How Does AI-Driven Real-Time 2D-to-3D Conversion Work?
Here's how the technology works:
- Depth Estimation: The AI analyzes the 2D content to estimate the depth information for different parts of the image. This involves recognizing objects, their distances, and their spatial relationships.
- Parallax Creation: Using the depth information, the AI generates different perspectives (views) that simulate what would be seen from slightly different angles, similar to how our eyes perceive depth.
- Stereoscopic Output: The converted views are then displayed in a manner suitable for stereoscopic viewing on a 3D display. In the case of a 3D lightfield display that we described above, these views are emitted directionally to create the 3D effect without needing special eyewear like 3D glasses.
While AI-driven 2D-to-3D conversion and 3D lightfield displays can be complementary, they are not necessarily interdependent. A 3D lightfield display can show content that is already in 3D without needing AI conversion. Conversely, AI-driven 2D-to-3D conversion can be applied to standard displays that support 3D, such as those requiring glasses.
Combining these technologies enhances the user experience. The AI-driven conversion enables 3D content to be generated from any 2D source, while the 3D lightfield display provides a natural, glasses-free 3D viewing experience. This synergy maximizes the utility of both technologies.
AI Dual-Light Sensor
An AI dual-light sensor is an advanced technology integrated into display devices, including smartphones and tablets. It consists of two sensors - typically an ambient light sensor and a proximity sensor - that work together with AI (artificial intelligence) algorithms to optimize the display's performance based on the surrounding lighting conditions.
How Does AI Dual-Light Sensor Work?
The AI dual-light sensor works its magic using mainly three components:
- Ambient Light Detection: The ambient light sensor continuously measures the intensity of the surrounding light. This helps the device adjust the screen brightness in real-time to ensure optimal visibility and comfort.
- Proximity Sensing: The proximity sensor detects how close the device is to the user. This is particularly useful for actions like turning off the display when the phone is held up to the ear during a call.
- AI Algorithms: The AI component analyzes the data from these sensors to make intelligent adjustments. This includes fine-tuning the brightness, contrast, and color balance to match the ambient lighting, thus enhancing the overall viewing experience.
The AI dual-light sensor impacts multiple aspect of the device's display, including brightness, visibility, and color accuracy. It dynamically adjusts the screen brightness based on the ambient light levels. In bright environments, it increases the brightness to improve visibility, while in darker settings, it dims the screen to reduce eye strain and conserve battery life.
By optimizing the brightness and contrast, the AI dual-light sensor ensures that the display remains readable and clear under varying lighting conditions, from bright sunlight to dim indoor lighting. Some advanced implementations also adjust the color temperature and saturation to maintain consistent and accurate color representation, enhancing the visual quality of images and videos.
In summary, the AI dual-light sensor is a sophisticated feature that significantly enhances the display performance of devices by intelligently adjusting multiple aspects like brightness, visibility, and color accuracy, based on the surrounding light conditions. This technology not only improves the user experience by ensuring optimal screen readability and comfort but also contributes to energy efficiency by managing the display's power consumption.

Frequently Asked Questions (FAQs)
What is HDR10+?
HDR10+ is an HDR (High Dynamic Range) standard that supports dynamic metadata, which allows the display to adapt and optimize the video content scene by scene, or even frame by frame.
What is HDR10+ video?
A video encoded using the HDR10+ standard is called an HDR10+ video.
What is HDR10+ support?
When a display (or another device, such as a disk-player) has HDR10+ support, it means that that device is capable of handling the HDR10+ content. It may not have the full technical capability to display the HDR10+ content in all of its intended glory, but it can interpret it and follow the instructions provided by the HDR10+ metadata to provide a decent output.
HDR10 vs HDR10+: which is better?
HDR10+ being an improvement over (and being a superset of) HDR10 is better. In addition to the features supported by HDR10, it additionally supports color depth higher than 10-bit and dynamic metadata (as opposed to the static metadata of HDR10). However, it is a newer standard and HDR10+ content is not as widely available as the HDR10 content, though it is catching up. So keep that in mind while making the final decision.
What is the difference between HDR10 and HDR10+?
HDR10 supports a color depth of 10-bit, whereas HDR10+ can support color depths higher than that (such as 12-bit). HDR10 supports static metadata, whereas HDR10+ supports dynamic metadata. HDR10 is an older standard and has wide support, including easier availability of HDR10 content. HDR10+ is catching up in those departments.
What is Dolby Vision? What does Dolby Vision do?
Dolby Vision, introduced in 2014, is the oldest HDR standard. It is simply the best; it supports 10-bit and 12-bit color depths, black level of at most 0.005 nits, resolutions up to 8K, and dynamic metadata. Some of its profiles also feature dual-layer video, which offers great visual experience and is also good for compatibility with the other HDR standards. It has strong support and extensive content availability.
What is Dolby Vision IQ?
Dolby Vision IQ is an enhanced version of Dolby Vision that adjusts the content according to the ambient light. Just like HDR10+ Adaptive, it instructs the display to set its properties, such as brightness and contrast, according to the light that it detects around the display.
Dolby Vision vs HDR10: which is better?
Both are mature standards, widely supported and with great content availability. However, Dolby Vision supports color depths higher than 10-bit too (whereas HDR10 is limited to 10-bit), and it has dynamic metadata (whereas HDR10 has static metadata). This makes Dolby Vision the better and more future-proof choice of the two.
HDR10+ vs Dolby Vision: which is better?
Both have matching technical capabilities, and both support dynamic metadata. However, Dolby Vision is an older standard with wider support and more extensive content availability. As such, it may be a better choice. However, not only is HDR10+ catching up, but it is free to use for content creators and has an annual license of a maximum of USD 10000 for some manufacturers, which may help push it to the number one position in the future.
Which Samsung phones support HDR10+?
Some examples are Samsung Galaxy S20 FE 2022, S22 5G, S22+ 5G, S22 Ultra 5G, S23, S23+, and S23 Ultra; Samsung Galaxy Z Fold4 and Z Flip4. There are many other models.
