Performance Analysis

Samsung Monitor MiniLED Odyssey Neo G9 visual performance and optical construction analysis

By Piseo — Dec 2022

With its claimed world’s-first curved MiniLED PC display, does Samsung succeed in reaching a high uniformity level over the entire display?

Report objectives

After several years and many announcements, Mini-LED backlights are coming to the market. According to manufacturers’ claims, they will allow LCD displays to offer a contrast similar to OLEDs, while providing high brightness. All this while offering reduced power consumption, a very thin form factor (thickness), and cost/price competitiveness with OLED.

With its MiniLED Odyssey Neo G9, Samsung announces a brighter image for better contrast – all in 8K.

To evaluate the benefits of this new type of backlight, DXOMARK and PISÉO – leaders in the assessment of consumer electronics quality and photonic system architecture, respectively – have teamed up to produce this report.

To evaluate the display quality of the Samsung Monitor MiniLED Odyssey Neo G9, DXOMARK carried out visual performance measurements. This report presents the test results and the performance comparison.

In order to understand the technology of the Samsung Monitor MiniLED Odyssey Neo G9 backlight, PISÉO analyzed the optical architecture of the unit. This report includes a description of the height of the optical films integrated between the MiniLED array and the LCD panel.

Based on their own analyses, DXOMARK and PISÉO carried out a cross-analysis to show the links between the user experience and backlight optical construction.

Approach to analysis

Tests and quality analysis of the performance of the Samsung Monitor MiniLED Odyssey Neo G9, based on DXOMARK protocol and covering:

Still content and video at high and standard dynamic range (HDR and SDR): brightness, contrast, EOTF, color, angular performance, halo
Artifacts: flicker, reflectance

To understand the technology of the Samsung Monitor MiniLED Odyssey Neo G9 backlight, PISÉO analyzed the optical architecture of the unit by:

Disassembling the Samsung Monitor MiniLED Odyssey Neo G9 to access the backlight unit
Delayering the optical stack
Analyzing the material and the mechanical structure of each layer
Analyzing the optical properties of each layer
Analyzing the LED emission characteristics and the local dimming features at LED board level

Main conclusions

MiniLED displays, and the future microLED displays, are clearly a disruption for the display industry. This is both in terms of performance, as analyzed in this report, and also in terms of supply chain. All the major consumer electronics manufacturers such as Apple, Samsung, TCL and Skyworth, and display device manufacturers, are testing the market with new products and adapting their supply chains. They are also trying to find differentiation in terms of design and choices of the right display architecture, as well as choice of the right components and modules.

This revolution is revealed by the YOLE Group’s different analysis capabilities. Teardown, supply chain, and reverse costing is done by YOLE System Plus. Performance analysis is done by PISÉO (e.g. measurement and analysis of the colorimetric deviation over the full screen, as illustrated in fig. 3). YOLE Intelligence studies company strategies and market evolution. Meanwhile, DXOMARK analyzes the visual performance of the display. Together, we have decided to launch a series of performance analysis reports to cover the most important MiniLED displays available on the market. Besides the Samsung Monitor MiniLED Odyssey Neo G9V, this year we have released studies of the following tablet and TVs:

Apple iPad Pro Mini-LED 12.9” – visual performance and optical construction analysis
Samsung TV MiniLED NEO QLED 65QN900A – visual performance and optical construction analysis
TCL 85X925 Pro 85” MiniLED 8K TV – visual performance and optical construction analysis

These reports are available and reveal the design differences of these displays, the supply chain choices, the key suppliers, and new technologies implemented.

Based on these reports, next year we will release an overview report with performance comparison and analysis of the four products.
