Hisense unveils new RGB Mini LED TV range
Published on
With its new TV ranges featuring RGB Mini LED technology, Hisense introduces a novel approach to LCD backlighting, where colors are generated directly from the light source. Mr. Jobs, the engineer at Hisense responsible for developing the new RGB Mini LED ranges, explains the technology’s challenges, benefits, and limitations compared to OLED and QD-OLED.
Understanding RGB Mini LED Technology
How does RGB Mini LED work and what advantages does it offer over a traditional Mini LED?
The traditional Mini LED backlight emits white light, typically from blue LEDs combined with a Quantum Dot layer. This light then passes through the LCD panel, composed of sub-pixels responsible for filtering the light to recreate the displayed colors on the screen.
In contrast, RGB Mini LED uses individual red, green, and blue Mini LEDs to directly produce primary colors at the source. The LCD panel no longer creates the color alone but modulates light already colored to form the final image.
This architecture presents several key benefits, including improved overall light efficiency of the TV, purer and more accurate colors, and a much wider color gamut potential, with up to 100% coverage of BT.2020 in the most advanced models.
In practice, this technology brings LCD closer to emissive operation, providing richer, more nuanced, and better-controlled colors.
What were the main technical challenges in developing this technology?
The main technical challenge of RGB Mini LED lies in the complex control of the backlight. Unlike a traditional Mini LED system that manages only light intensity, RGB Mini LED needs to control the three color components simultaneously for each screen zone in real-time.
Hisense relies on the latest Hi-View Engine 7 chipset to analyze and adjust the image in real-time for precise control of RGB Mini LED backlighting.
Image Quality and Concrete Benefits
What measurable benefits does RGB Mini LED bring in terms of color volume and color precision?
RGB Mini LED outperforms other technologies in color volume capability, reaching beyond standard color spaces like DCI-P3 and covering the full BT.2020 spectrum. This technology delivers richer and more faithful colors, enhancing HDR content significantly.
Additionally, RGB Mini LED improves color precision, with some models achieving a Delta E below 1, ensuring high color fidelity.
In real-world applications, this translates to more realistic and nuanced images, especially in HDR content where brightness and saturation play a crucial role.
Does RGB Mini LED also improve blooming and contrast management?
RGB Mini LED does not directly affect blooming, which is more related to how the backlight is controlled spatially rather than the type of light used.
However, it indirectly contributes to better image control through precise color and brightness management.
Positioning Against Other Technologies
How does RGB Mini LED compare to traditional Mini LED, QLED, and OLED TVs?
RGB Mini LED represents a significant evolution in LCD technology, combining advantages of traditional Mini LED TVs with advanced color processing.
Compared to OLED displays, RGB Mini LED offers higher maximum brightness, enhancing HDR impact but still falls behind in absolute black level and perceived contrast management.
Against QD-OLED, RGB Mini LED goes further in color processing by directly managing colors at the light source, extending the color gamut potential even more.
In comparison to QLED TVs, RGB Mini LED stands out for its absence of white light filtering, improving light efficiency and color purity.
Overall, RGB Mini LED offers high brightness, wide color gamut, and increased color precision, making it a promising solution for enhancing LCD image quality.
Can this technology become a real long-term alternative to OLED?
RGB Mini LED doesn’t aim to reproduce OLED’s absolute black levels but rather redefine how LCD TVs produce images. The technology provides tangible improvements in color precision, richness, and HDR content management, complementing OLED in specific aspects.
Real-world Usage/User Experience
In which use cases does this technology offer the most benefits: cinema, sports, or gaming?
RGB Mini LED excels in applications requiring high brightness, color richness, and readability. It benefits movies, sports events, and video gaming in different ways.
For 4K HDR movies, the technology enhances color rendering and brightness intensity for a more immersive viewing experience.
In sports, high brightness aids visibility, while motion handling contributes to sharper movements.
In gaming, color accuracy and contrast contribute to a vivid and responsive gaming environment.
Does this architecture impact responsiveness or input lag for gaming?
RGB Mini LED’s complex backlight control doesn’t significantly impact input lag in gaming, as modern TVs optimize signal processing to reduce display delays.
Overall, RGB Mini LED provides a smooth and responsive gaming experience similar to high-end Mini LED or OLED TVs.
Is video processing and AI tailored specifically for RGB Mini LED?
Yes, video processing is optimized to leverage RGB Mini LED’s potential, ensuring precise color and brightness adjustments for accurate image reproduction.
Hisense’s Hi-View Engine 7 chipset uses AI to synchronize video signals, LCD panels, and RGB Mini LED backlighting for enhanced image quality.
Challenges/Future of the Technology
Does this architecture impact energy consumption or TV durability?
RGB Mini LED’s efficient light production can positively impact energy consumption. The technology limits light losses and maximizes light utilization, potentially reducing power consumption compared to OLED or traditional Mini LED TVs.
RGB Mini LED also boasts long-lasting LEDs, providing durability that exceeds the usual TV replacement cycle.
What are the main limitations of RGB Mini LED today?
RGB Mini LED still faces challenges in contrast management and blooming control, not achieving OLED’s absolute black levels and facing complexities in simultaneous RGB brightness control.
Work is ongoing to expand the color gamut and improve color precision and texture rendering.
Can we expect a rapid democratization of this technology in more accessible ranges?
Currently, RGB Mini LED remains in premium ranges due to complex implementation requirements and processing power. As with most TV innovations, the technology is expected to gradually move to more affordable models with industrial and technological advancements.
The goal is to progressively make RGB Mini LED more accessible in the coming years as optimization progresses.
