TCL华星赵军自然光护眼显示技术访谈荣登《自然》Nature Custom Media报道
对话TCL科技高级副总裁、TCL华星首席执行官赵军
TCL华星作为全球领先的显示面板制造商，在SID2026行业盛会，展示了多款自然光护眼显示技术，Nature Custom Media深度对话TCL华星首席执行官赵军，全面阐述APEX自然光显示技术。TCL华星首席执行官赵军表示，随着人们在屏幕前停留的时间越来越长，开发能够产生更接近自然光、更符合人体视觉生理需求的显示产品至关重要。同时，他也指出，行业需要更科学的方法来评估显示技术的输出质量。
问：TCL华星为何提出“自然光显示技术”这一理念？
赵军：传统的显示屏开发往往陷入对单一参数的极致追求，如：蓝光发射、偏振或频闪。但人眼并非仪器，我们的视觉体验是由发射光线进入眼睛并被视觉系统处理的整个通路共同塑造的，而非由任何单一指标孤立地塑造。
为了更好地反映这一点，TCL华星一直致力于开发更接近自然光的显示技术，并将自然光用作显示产品设计和评估的输出参考基准。我们系统全面总结自然光及其光环境为参考基准，设计了六个维度的技术参数：宽光谱、无偏振、连续性、漫反射、节律性、空间性等。
问：您能否举例说明这一理念在实践中是如何应用的？
赵军：宽光谱就是一个很好的例子。由于日光质量随气候、地理和季节而变化，研究人员在将显示光与“自然光”进行对比时，需要一个统一的参考点。在实践中，通常使用“CIE D65标准光源”来代表典型日光的光谱功率分布。这使得我们能够设计出光谱分布更宽广、更连续的显示屏，避免了传统RGB显示屏幕(特别是在蓝光区域)中常见的窄峰现象。

TCL华星深耕这一技术路径，既顺应了显示领域科学证据的不断累积，验证了宽光谱对视觉生理的友好性，也精准回应了用户在阅读、校对等精细化作业场景下的护眼刚需。
除了光谱特性外，自然光在一天之中也会不断变化。显示屏可以通过调节亮度、色温甚至调整特定光谱段，来支持人体的昼夜节律。
另一个例子是偏振特性。自然光没有固定的偏振方向，而LCD屏通常为线偏振光。TCL华星正在研发一种能更接近自然随机非偏振状态的屏幕。通过设计研发消偏振光学层，将偏振光的振动方向随机化，使显示输出更接近自然光的偏振特性。

此外，显示屏幕调制光源时随时间波动，即“频闪”。即使人眼无法察觉，亮度的细微波动仍会导致视觉疲劳。TCL华星的研究人员正与温州医科大学附属眼视光医院的医生们合作，研究如何通过提高刷新率和改进调光方案来减轻视疲劳。
问：这一研究理念是如何通过产学研协作实现落地的？
赵军：自2005年以来，TCL华星便持续与多家医院、大学及标准机构开展合作，包括中山大学中山眼科中心、中国标准化研究院和北京同仁医院等，共同探究显示输出的各维度指标与视觉疲劳及眼健康之间的关联。
早期工作主要集中在偏振与视觉疲劳的关系上，而近期的研究则更多关注刷新率、OLED亮度调制以及宽光谱输出。这些科研合作为TCL华星制定“自然光相似度”的显示开发准则提供了坚实的理论支撑。
问：TCL华星未来的研究方向是什么？
赵军：我们的目标是更深层次地理解光与人眼的交互机制，找寻能够提升视觉舒适度的关键显示参数，并使屏幕输出更接近人们在现实自然世界的感知体验。我们期待与更多学术机构和临床专家合作，进一步验证并扩展我们在这一领域的发现。

Why did CSOT propose natural-light display technology?
Traditionally, the development of displays screens has optimized individual parameters, such as blue-light emission, polarization or flicker, one at a time. But our visual experience is shaped by the entire pathway through which emitted light enters the eye and is processed by the visual system, rather than shaped by any single metric in isolation.
To better reflect this, we have been developing display technology at CSOT that more closely resembles the experience of natural light, using that light as a reference for how display output can be designed and evaluated. Our approach considers several design parameters, including the spectrum distribution of light, polarization of emitted light, display flicker,adaptation to circadian lighting conditions, diffuse reflection on displays, and spatial viewing conditions, such as viewing distance.
Could you highlight examples of how this works in practice?
The spectrum distribution of light is one example. Because the quality of daylight changes with climate, geography and season, researchers need a consistent reference point when comparing display light with ‘natural’ light. In practice, they often use a standard called ‘CIE illuminant D65’ to represent typical daylight, based on how much light is distributed at different wavelengths. This allows display spectra to be designed with a broader and more continuous distribution, avoiding the narrow peaks typically seen in conventional RGB-based displays, particularly in the blue region.
Although direct evidence in display settings is still emerging, studies in lighting research suggest that broader, more daylight-like ranges of spectra may be more comfortable and provide better support for tasks such as reading and proofreading, which is why CSOT is pursuing this.
Beyond its spectral properties, natural light also varies over the course of the day, and displays can support circadian rhythms by adapting brightness and colour, even adjusting specific spectra.
Another example is the polarization of emitted light. Natural daylight does not have a fixed direction of polarization, whereas LCDs typically produce linearly polarized light, with waves vibrating in a single direction. CSOT is developing screens which produce light that is polarized in a more natural way through a depolarizing optical layer designed to randomize the vibration direction of polarized light, bringing display output closer to the polarization characteristics of natural light.
Light from displays can also fluctuate over time, a phenomenon known as flicker. Even when not consciously perceived, these subtle fluctuations in brightness may still contribute to visual fatigue over time. Working with scientists at the National Engineering Research Center for Ophthalmology and Optometry at Wenzhou Medical University, in Wenzhou, CSOT researchers have been studying how higher ‘refresh rates’ and improved dimming approaches may help reduce fatigue.
How has this idea been shaped by research and collaboration?
Since the late 2000s, CSOT has also worked with hospitals, universities and standards institutions, including the Zhongshan Ophthalmic Center at Sun Yat-sen University in Guangzhou, China National Institute of Standardization and Beijing Tongren Hospital, to examine how some aspects of display screen output relate to visual fatigue and health.
Early work focused on polarization and visual strain, while more recent studies have looked at refresh rate, OLED luminance modulation and broad-spectrum output. More recently, research collaboration has helped integrate this work with CSOT’s broader principles for developing displays that more closely align with natural light.
What’s next for your research?
Our goals are to better understand how light interacts with the eye, to identify display parameters that support visual comfort, and to bring screen output closer to people’s experience of ambient light in the real world. We are excited to work with more academics and clinicians to help test and extend our findings in this area.
