OLED vs. LCD: The Evolution of Energy Efficiency in TVs
A decade ago, when OLED TVs first emerged, there was a common belief: LCD TVs seemed energy-efficient, but their backlights were always on, leading to constant power consumption. OLED TVs, on the other hand, appeared to consume more power, but only at peak levels. In reality, OLED power consumption could drop close to zero when displaying a completely black screen.
However, with the advent of HDR technology and the development of MINI LED backlighting, this narrative is becoming history. The 2025 CES showcased how companies like Hisense are embracing RGB-MINI LED backlighting, transitioning HDR local dimming from black-and-white to full-color control. This advancement significantly enhances the dynamic energy-saving capabilities of LCD displays, marking a major milestone beyond just picture quality.
RGB Local Dimming: The Big Three Converge
At the 2025 CES, Hisense unveiled its 116-inch RGB-Mini LED TV and introduced its RGB Local Dimming Display Technology, also known as TriChroma LED.
As Hisense's flagship technology for CES 2025, RGB-Mini LED is hailed as a groundbreaking innovation in color accuracy and energy efficiency. Industry experts believe that upgrading HDR local dimming from monochrome to full-color is the future. Hisense has overcome challenges in RGB-Mini LED chip design, AI-driven local dimming, and RGB 3D color control, securing its leadership in the RGB local dimming era with multiple "world-first" achievements.
Hisense plans to release more RGB local dimming TVs, forming a new flagship series. Additionally, the company aims to integrate RGB local dimming into medical and reference-grade displays, further solidifying its position as a global leader in display technology.
A day before CES, Samsung showcased its first 98-inch LCD display with RGB Micro LED backlighting. By switching from Mini LED to Micro LED, Samsung significantly increased the number of LEDs, enhancing brightness, dimming zones, and energy efficiency.
Meanwhile, TCL is rumored to launch RGB-LED backlit TVs in 2025, though details remain scarce. With Samsung, Hisense, and TCL—the top three global TV manufacturers—all converging on RGB backlighting, Hisense has already gained a competitive edge with its advanced LED chip manufacturing and proprietary AI image processing technology.
Color, Dimming, and Energy Efficiency: The Triple Advantage
Why RGB LED backlighting? Sony provided an answer back in 2008. As the first brand to experiment with RGB LED backlighting (though limited by the technology of the time), Sony highlighted the potential for higher color gamut and accuracy.
Hisense emphasizes that its RGB-Mini LED technology delivers a wider color gamut and more vibrant colors. The TV achieves 97% BT.2020 color gamut, 87% color volume, and high color purity levels of 99%/92%/100%, setting new benchmarks for flat-panel displays. Notably, the green spectrum has been refined using Hisense's narrow-spectrum epitaxial growth process, reducing the G-chip spectrum width by 27% and significantly improving color accuracy.
RGB local dimming also enhances control over brightness and color. Hisense's RGB-Mini LED TV features 3*26-bit color control precision, a threefold improvement over traditional black-and-white dimming. Advanced LED chips and high-quality driver ICs further boost dimming accuracy, ushering in a new era of RGB micro-dimming.
Moreover, RGB local dimming improves energy efficiency. Hisense claims its RGB-Mini LED technology achieves "super-first-class energy efficiency," with a light-color efficiency ratio four times higher than QD-OLED. Compared to QD-OLED and traditional Mini LED TVs, Hisense's RGB-Mini LED TVs save over 20% energy. By directly emitting light through RGB semiconductor chips without the need for phosphor or quantum dot conversion, RGB local dimming eliminates efficiency losses and dynamically adjusts brightness for each color, optimizing energy use.
In summary, RGB local dimming represents an upgrade in color, HDR content compatibility, and energy efficiency.
The Triple Significance of RGB Local Dimming
Industry experts highlight three key implications of RGB-Mini LED technology:
1. Superior Picture Quality: RGB local dimming breaks the color limitations of LCD TVs, a critical factor in high-end competition. However, some argue that while picture quality improvements are significant, they may not create a generational gap, making them less of a game-changer. [图片3]
2. Future Content Standards: Traditional HDR focuses on brightness adjustments. The emergence of RGB-HDR standards could reshape content creation. With LED cinema screens, conference displays, Micro LED, and OLED all adopting RGB local dimming, LCD's entry into this space completes the ecosystem, potentially driving the next generation of HDR content standards.
3. Energy Efficiency: RGB-Mini LED's energy-saving potential is substantial. Without phosphor or quantum dot conversion, RGB LEDs are inherently more efficient. As LED technology advances, their performance will only improve. Dynamic RGB local dimming further enhances energy efficiency by adjusting backlight power based on content needs.
Hisense's RGB-Mini LED TVs already save 20% more energy than traditional TVs, prompting discussions about revising energy efficiency standards and introducing dynamic energy consumption ratings.
The Future of RGB Local Dimming
Energy conservation and sustainable development are central to modern civilization. As displays grow larger and more ubiquitous, RGB-Mini LED's energy efficiency could be a game-changer. If energy standards and market entry thresholds evolve alongside RGB-Mini LED advancements, RGB local dimming will no longer be a luxury feature but a necessity for responsible, low-carbon products.
Similarly, if future high-end content adopts RGB-HDR standards, only RGB local dimming displays will fully realize its value, making RGB local dimming indispensable.
Looking ahead, LED backlighting may enter a "polarized" era. Since LCDs only process polarized light, traditional light sources waste 50% of their output. Advances in polarized LED research could lead to RGB-LED polarized light sources, further boosting LCD energy efficiency and driving sustainable industry upgrades.
For example, recent breakthroughs by Central South University and Oxford University have demonstrated significant improvements in LED polarization efficiency, paving the way for more energy-efficient displays.
In conclusion, while the market impact of RGB-Mini LED's triple advantages—picture quality, HDR content, and energy efficiency—remains to be seen, its status as a consensus among the top three TV manufacturers makes it a pivotal battleground for 2025. Will 2025 mark the explosive rise of RGB local dimming? Only time will tell!
