From winning the CES 2026 Best of Innovation Award to being named one of TIME magazine’s “Best Inventions of the Year,” Samsung’s Micro RGB TV has earned global recognition. Building on its debut as the world’s first Micro RGB TV, Samsung Electronics is expanding the lineup this year with a 130-inch ultra-large model, setting a new benchmark for next-generation television technology.
From adopting micro-size RGB (red, green and blue) LEDs as a backlight unit to pursuing enhanced color expression and integrating AI technology for ultra-large displays, the development of the Micro RGB TV was a continuous series of firsts — with virtually no reference points to guide the process.
Samsung Newsroom spoke with Insang Hwang of the Visual Display (VD) Business Division’s Product Planning Group to learn more about how this new category of the Micro RGB TV was developed.
▲ Micro RGB TV recognized for its technological excellence in the global market.
Creating a New Category With No Reference
The Micro RGB TV began as a project to create an entirely new category in the TV market. Hwang recalled, “Because the mission was to create a category that didn’t previously exist, every department — from development to sales and marketing — had to work together with a shared sense of urgency and responsibility.”
One of the biggest challenges was the absence of any reference point. The team had to develop new technologies and products from scratch while simultaneously defining the value they could deliver to consumers. “We went beyond simply applying RGB light sources,” he said. “We developed a proprietary concept called ‘Micro RGB,’ which miniaturized even the backlight unit itself to the micro level.”
Pursuing 100% BT.2020 — The “Ultimate Color Gamut”
At the core of the Micro RGB TV is its color reproduction. By applying RGB LEDs as the backlight unit, the display achieves wide and highly accurate color reproduction.
“Although the Micro RGB TV started with the goal of delivering richer color reproduction, there was no clearly defined industry standard at the time,” Hwang said. “We felt a strong sense of responsibility, believing that the conditions we set could become the new standard for the market. That’s why we set the ambitious goal of achieving ‘100% BT.2020’ — the ultra-high-definition color standard defined by the International Telecommunication Union (ITU) and often referred to as the ‘ultimate color gamut.’”
▲ Micro RGB TV achieves 100% BT.2020 — the “ultimate color gamut” — setting a new standard in the TV market. Achieving 100% BT.2020 means that a level of color reproduction once limited to professional monitors can now be experienced on TVs — one of the most widely used displays in everyday home environments. It also marks a significant advancement in the technical standards of the display industry.
The journey, however, was far from easy. “In the early stages of development, we struggled to reach the target values,” Hwang recalled. “However, through persistent efforts to achieve perfect color reproduction, the development team was ultimately able to meet its goal.” He added, “It wasn’t just about developing new technology. We also worked to establish measurable standards to validate its performance.”
Bringing Cutting-Edge Technology Into Everyday Viewing
For product planners, the top priority is to convert advanced technology into an experience that users can easily perceive in everyday life. “We continuously thought about how to translate Micro RGB’s powerful hardware performance into a practical viewing experience,” Hwang said. “We focused on making its key strength — color — something users can feel naturally in everyday content while delivering an immersive viewing experience.”
“While Micro RGB achieves one of the highest color gamuts available in TVs today, only a limited amount of content fully utilizes it,” he noted. “So we enhanced software capabilities to ensure users can experience the difference across a wider range of content — from HDR content to everyday content such as OTT streaming and sports.”
One of the key features is Micro RGB Color Booster Pro. Hwang explained, “Leveraging a high-performance neural processing unit (NPU), AI analyzes content in real time to enhance color expression with precision. This allows users to enjoy Micro RGB’s vivid color performance not only in HDR content but also in everyday viewing.”
▲ Hwang explained that Micro RGB Color Booster Pro enhances color for a richer and more vivid viewing experience. He added, “For example, in soccer — one of the sports most frequently watched on TVs — the newly introduced AI Soccer Mode Pro automatically detects the content and enhances colors such as the grass and team uniforms. With the global football season kicking off in June, it’s a feature worth noting for those seeking a more immersive viewing experience.”
In addition, the TV incorporates a Glare Free feature designed for real-world viewing environments. “We applied glare-free technology so users can consistently enjoy Micro RGB’s exceptional color performance regardless of lighting conditions,” Hwang explained. “Whether in a dark room or a brightly lit space, viewers can stay fully immersed without reflections interfering with the screen.”
Scaling Immersion With a 130-Inch Display
The newly introduced 130-inch ultra-large model delivers an overwhelming sense of immersion, as if the entire wall comes to life. As screen size increases, maintaining image detail becomes increasingly critical.
Hwang said, “We equipped the TV with Supersize Picture Enhancer, an AI-powered picture quality technology optimized for ultra-large displays. Thanks to this, viewers can enjoy Micro RGB’s rich colors and sharp image quality without distortion or pixelation.”
The sound experience and design were also significantly enhanced. “With a 160W 10.4.2-channel speaker system, the TV delivers immersive sound that fills the entire space without the need for external speakers,” he added.
▲ Micro RGB TV features a wall-mount design that integrates seamlessly with the space, enhancing immersion. The Micro RGB TV’s signature wall-mount design further reinforces immersion by blending the display seamlessly into its surroundings. “We developed a proprietary pocket structure and wall-mount bracket1 so the TV can sit flush against the wall with virtually no gap,” Hwang explained. “We focused on delivering an optimized viewing experience for ultra-large screens across picture quality, sound and design.”
Toward the Next-Generation Screen Experience
The Micro RGB TV goes beyond technological advancement — it expands the boundaries of how users experience screens in everyday life while setting new standards for the industry.
“Samsung TVs are evolving into screens that seamlessly integrate into users’ lifestyles and living spaces, understanding their preferences through data and enabling interactions,” Hwang said. “They will go beyond content consumption to become powerful platforms that connect limitless experiences and services.”
As the Micro RGB TV continues to push the boundaries of innovation, Samsung is paving the way for the next generation of screen experiences.

Samsung Wallet provides an e-wallet service to its customers through wallet cards, as well as offering features designed to enhance user engagement and drive business growth for partners. Sending push notifications to users is such a feature. Partners can send push notifications to users' wallet cards directly, using pre-approved message templates.
These notifications can be used to send promotional messages or alert users about important updates. This article demonstrates a complete implementation of the Send Notification API.
In the example scenario, we send a notification to a user's wallet card from a partner's server using this API.
System requirements
The Notification API has the following prerequisites:
Complete the onboarding procedure to obtain the required security certificates if you are new to Samsung Wallet.
Now create your wallet card. Follow the Step 1 - Create Wallet Card Template section of the documentation.
Create your notification template and request for approval. Follow the Notification Workflow Overview to complete this step. Remember to check the template to detect prohibited content. No additional approval is required if it passes.
Get permission from Samsung to use the Send Notification API. Reach out to Samsung Developer Support for further support. API fundamentals
As an authorized partner, you can send notifications to the users linked to your card, using the Send Notification API from your server.
Endpoint: The endpoint below processes the notification requests.
URL https://tsapi-card.walletsvc.samsung.com/{cc2}/wltex/cards/{cardId}/notifications/{templateId}/send Headers: Header information is required to ensure secure communication between the Samsung server and the partner server.
Authorization: Bearer token for authentication. Refer to JSON Web Token documentation for specifications. x-smcs-partner-id: Unique partner identifier required for API access. x-request-id: A unique UUID string that identifies each request. Body: A payload including a parameter named ndata possessing a JWT token that contains the relevant data to identify the card user.
See the official documentation for detailed API specifications.
API implementation process
The Send Notification API allows you to send personalized push notifications to users. Download the sample source code and follow the step-by-step process below for a better understanding of the implementation of the API.
Step 1: Managing cryptographic keys
Cryptographic keys are needed for authorization purposes. In this step, use the certificate you obtained during the onboarding process to extract the necessary keys. These keys are needed for JWT token generation.
Extracting the public keys
Extract the public keys from the partner.crt and samsung.crt certificate files.
def getPublicKey(crt_path): try: with open(crt_path, "rb") as f: crt_data = f.read() certificate = x509.load_pem_x509_certificate(crt_data, default_backend()) public_key = certificate.public_key() public_key_pem = public_key.public_bytes( encoding=serialization.Encoding.PEM, format=serialization.PublicFormat.SubjectPublicKeyInfo ) return public_key_pem except Exception as error: print(f"Error reading public key from {crt_path}: {error}") return None Extracting the private key
Extract the private key from the .pem file generated during the onboarding process.
def getPrivateKey(pem_path): try: with open(pem_path, "rb") as data: private_key = serialization.load_pem_private_key( data.read(), password=None, backend=default_backend() ) return private_key except Exception as error: print(f"Error reading private key from {pem_path}: {error}") return None Step 2: Constructing the authorization token
An authorization token is needed to validate the API request. Construct an authorization header with AUTH as the payload content type and include the certificate and partner IDs. Retrieve these IDs from My account > Encryption Management in the Wallet Partner Portal, then build the payload and construct the authorization token.
The following code snippet implements the actions described.
def generateAuthToken(partnerId, certificateId, utcTimestamp, privateKey, cardId, cc2, templateId): auth_header = { "cty": "AUTH", "ver": 3, "certificateId": certificateId, "partnerId": partnerId, "utc": utcTimestamp, "alg": "RS256" } auth_payload = { "API": { "method": "POST", "path": f"/wltex/cards/{cardId}/notifications/{templateId}/send" }, } auth_token = jwt.encode( payload=auth_payload, key=privateKey, algorithm='RS256', headers=auth_header ) return auth_token Step 3: Constructing the notification data token
The request payload requires the ndata parameter, which is a JWT token that contains information about the notification data and the cards’ identifiers. Follow these steps to construct the ndata token.
Defining the notification object
The notification object is a JSON structured data object containing a list of reference IDs and the data. The reference IDs identify the specific cards to send the push notification to. You can use a list of reference IDs to send the push notification to multiple recipients at a time. The data contains the name-value pairs used in the notification template. In our sample notification template, we used two name-value pairs (name and insert_end_date).
notifcationObject = { "refIds": [ "4afb049c-efef-43ca-8f03-1df55243477c" ], "data": { "name": "Premium", "insert_end_date": "12/12/2026" } } Constructing the notification data JWT token
Next, construct the JWT token for notification data (ndata). You can get more information about the JWT format in the "Card Data Token" section of this documentation.
def generateCDataToken(partnerId, samsungPublicKey, partnerPrivateKey, certificateId, utcTimestamp, data): jwe_header = { "alg": "RSA1_5", "enc": "A128GCM" } jwe_token = jwe.encrypt( data, samsungPublicKey, encryption=jwe_header["enc"], algorithm=jwe_header["alg"] ) print(f"jwe_token: \n{jwe_token}\n") jws_header = { "alg": "RS256", "cty": "NOTIFICATION", "ver": 3, "certificateId": certificateId, "partnerId": partnerId, "utc": utcTimestamp, } jws_token = jws.sign( jwe_token, key=partnerPrivateKey, algorithm='RS256', headers=jws_header ) print(f"jws_token: \n{jws_token}\n") return jws_token Step 4: Building and executing the POST request
Construct the HTTP POST request to send the push notification using the following code structure.
# --- Prepare JSON body (Python dictionary) --- payload = { "ndata": nData } # --- Build HTTP Request --- headers = { "Authorization": "Bearer " + authToken, "x-smcs-partner-id": partnerId, "x-request-id": requestId, "Content-Type": "application/json" } # --- Execute HTTP Request --- try: response = requests.post(endpoint, json=payload, headers=headers) response.raise_for_status() print("Wallet Card Template Notificatiom: " + json.dumps(response.json())) except requests.exceptions.RequestException as e: print("Failed to notify the Wallet Card user:") print(f"Error: {e}") if response: print("Response body:", response.text) Running the sample application
Once the four steps described above are implemented, open the sample project and do the following:
Update the partner_id, certificate_id, card_id, and template_id values in src/main.py with your actual values. Place your partner.crt, samsung.crt and private_key.pem files in the /cert directory. Install all dependent libraries listed in the requirements.txt file. Run the main script in the terminal. After the script is executed successfully, a push notification is sent to the user's wallet.
Conclusion
Now that you have implemented the Send Notification API sample application successfully, you can implement this API with your server to send customized push notifications.

The Galaxy Watch has a built-in accelerometer sensor that measures movement or acceleration forces in three dimensions (X,Y, and Z axes). This data is commonly used for tracking movement, detecting gestures, and enabling fitness-related features like sleep tracking, fall detection, step counting, running, and workout tracking.
The accelerometer measures acceleration along three axes:
X-axis: Side-to-side movement.
Y-axis: Forward-and-backward movement.
Z-axis: Up-and-down movement.
Figure 1: Axis directions for the accelerometer sensor
Acceleration is typically measured in meters per second squared (m/s²) or gravity units (g), where 1g = 9.81 m/s².
This article describes how to read accelerometer sensor data from a Galaxy Watch running Wear OS powered by Samsung and also shows the conversion procedure for the raw data.
Environment Setup
Android Studio IDE is used for developing Wear OS applications. The examples in this article use Java, but Kotlin can also be used. Going forward, this article assumes you have already installed the latest Android Studio version on your PC.
Read Accelerometer Data from Galaxy Watch
To get accelerometer data, we need to use Android Sensor APIs from the SensorManager library.
To retrieve accelerometer data from your Galaxy Watch:
Create a new Wear OS project in Android Studio by selecting File > New Project > Wear OS > Empty Activity > Finish. Set the minimum SDK version to API 30 or higher.
Add permission to access the sensor into the manifest file (AndroidManifest.xml):
<uses-feature android:name="android.hardware.sensor.accelerometer" /> You do not need to manually set the runtime permission to access the accelerometer. This permission is granted by default.
Design your preferred layout (.xml file) to show accelerometer data on the Galaxy Watch screen. This example uses three TextViews in a Constraint Layout to show the output of the three axes of the sensor. You can also check the result in the Logcat window in Android Studio. <TextView android:id="@+id/textViewX" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="8dp" android:text="X" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintHorizontal_bias="0.207" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toBottomOf="@+id/textView2" /> For more detailed code, check the sample application.
Use the SensorManager library and SensorEventListener to read accelerometer data. To implement them: Initialize the SensorManager library globally: private SensorManager sensorManager; To retrieve android.hardware.SensorManager for accessing sensors, you have to use getSystemService(). sensorManager = SensorManager.getSystemService(Context.SENSOR_SERVICE); As our target is the accelerometer sensor specifically, it is set as the default sensor here. It is recommended to always check the sensor availability before using it in the code. The procedure to do so is explained in this guide.
To make the accelerometer the default sensor:
Sensor sensor = sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER); To get continuous data from your Galaxy Watch, you need to register a listener to notify you if there is new data. This is done using a SensorEeventListener in Android’s Sensor API. sensorManager.registerListener(listener, sensor, SensorManager.SENSOR_DELAY_NORMAL); The listener method onSensorChanged() is called whenever new data is available. The new data is processed in the listener. private SensorEventListener listener = new SensorEventListener() { @Override public void onSensorChanged(SensorEvent sensorEvent) { // for absolute values X = Math.abs(sensorEvent.values[0]); //0 -> X Axis 1-> Y Axis 2 -> Z Axis Y = Math.abs(sensorEvent.values[1]); Z = Math.abs(sensorEvent.values[2]); Log.e("--MainActivityTag--", "X: " + X + "\n" + "Y: " + Y + "\n" + "Z: " + Z); // do whatever you want to do with the data } @Override public void onAccuracyChanged(Sensor sensor, int i) { } }; Here, onAccuracyChanged(Sensor sensor, int i) is a part of the SensorEventListener interface. It is triggered when the accuracy of a sensor changes. However, for the accelerometer, it is called rarely, as the accelerometer data accuracy usually remains constant.
Unregister the listener when the data collection is over. Otherwise, it can cause unusual battery consumption. Test the Code Sample
You can check out the sample app (download it using the link below) and try it out on your Galaxy Watch 4 and later.
AccelerometerDataExample.zip (332.2 KB)
Run the sample project on your Galaxy Watch. You will see the following screen.
Figure 2: Output of the sample project (accelerometer data on Galaxy Watch)
Accelerometer Data Units and Conversion for Galaxy Watch
In the application end, raw accelerometer data from Galaxy Watch is converted into meters per second squared (m/s²).
Equation
raw data * 9.80665 (gravity force) / 4096 (8g rescale)
Example
Assume,
raw_x = raw data received from the sensor
acc_x = accelerometer data in application end
if raw_x = 100
acc_x = 100 * 9.80665 / 4096
After this, acc_x is received by the application, containing the Acceleration value in m/s².
Convert the Data into G-Force Units
The conversion from m/s² to g is: 1 / 9.80665
So 1 m/s² =0.10197g
Information about the Accelerometer Sensor
The accelerometer provides the 3 axis values separately. The sampling rate of the accelerometer is usually a multiple of 50 Hz, but 100 Hz is also supported. The range of the accelerometer is +- 8G. Sampling rate:
#Maximum Delay: https://developer.android.com/reference/android/hardware/Sensor#getMaxDelay() // 160 msec
#Minimum Delay: https://developer.android.com/reference/android/hardware/Sensor#getMinDelay() // 10 msec It is always recommended to read calibrated data to avoid unnecessary noise. To get the result in g-force units, you need to divide the accelerometer values by 4096 (along every axis). It is recommended to use a filter while reading any sensor data. Make sure to always unregister the listener and stop all the services after using. Failure to do so can cause excessive battery drain. There are some restrictions of using background services for Galaxy Watch. Conclusion
For a Galaxy Watch running Wear OS powered by Samsung, accelerometer data is widely used in fitness tracking, fall detection, gesture recognition and motion analysis. Moreover, data conversion enables precise tracking for applications.
In this article, we’ve seen one of the ways of reading accelerometer sensor data on a Galaxy Watch running Wear OS powered by Samsung. You can also read sensor data using the Samsung Health Sensor SDK. For more details on Samsung Health, check here.
