2024年,全球LCD背光单元(BLU)市场IMARC Group达135亿美元。该市场正在经历显着增长,这主要是由量子点增强和迷你 LED 等技术进步、对高分辨率 4K 和 8K 显示器的日益青睐以及软包装使用的增长所推动的。汽车、医疗和消费电子等各领域的应用扩展也为市场成长做出了积极贡献。
LCD 背光单元 (BLU) 是液晶显示器 (LCD) 的关键组件,为萤幕提供必要的照明以使其可见。它负责将光线均匀分布在液晶面板后面,确保最佳的亮度和对比。 BLU 通常由多个组件组成。主要元件是光源,例如发光二极体 (LED) 或冷阴极萤光灯 (CCFL)。 LED 因其能源效率、更长的使用寿命和紧凑的尺寸而成为主要光源。 LED 产生的光线随后被引导通过漫射器,漫射器将光线均匀地散射到 LCD 面板上。反射器通常放置在漫射器后面,透过将任何杂散光反射回面板来提高光效率。在一些 BLU 设计中,采用光导和棱镜膜等附加组件来增强光分布和控制。光导有助于将光线引导至整个显示区域,而棱镜膜可用于改善视角并减少眩光。近年来,BLU 受到关注,因为它们是 LCD 的重要组件,直接影响整体显示品质。它还决定了萤幕的亮度、色彩再现和对比度水平。
推动市场的主要因素之一是液晶显示器在电视、电脑显示器、智慧型手机、汽车显示器和标誌系统等各种应用中的广泛采用。对 LCD 面板的需求直接转化为对 BLU 的需求,因为它们对于照亮 LCD 萤幕至关重要。此外,消费者对亮度、对比、色彩准确度和能源效率更高的高品质显示器的要求越来越高。 BLU 透过为 LCD 萤幕提供均匀且最佳的照明,在满足这些需求方面发挥着至关重要的作用。除此之外,汽车产业正在见证资讯娱乐系统、仪表板和平视显示器中 LCD 显示器的采用激增。这种成长是由先进驾驶辅助系统 (ADAS) 的整合以及对互动式和沈浸式车内体验的需求等因素所推动的。因此,由于对专为汽车显示器设计的专用 BLU 的需求不断增长,BLU 市场正在经历显着增长。除此之外,各行各业不断出现更薄、更轻的显示器趋势,这推动了纤薄紧凑的 BLU 的开发,这些 BLU 可以适应更薄的外形尺寸,同时保持高亮度和效率。除此之外,智慧型手机、平板电脑、笔记型电脑和便携式消费性电子产品等应用也推动了对具有纤薄外形和轻量化设计的 BLU 的需求。此外,背光技术的不断进步对BLU市场产生了重大影响。例如,更先进的LED背光解决方案(例如局部调光和量子点技术)的发展提高了LCD显示器的性能,从而推动了对相应BLU的需求。
The global LCD backlight unit (BLU) market size reached USD 13.5 Billion in 2024. Looking forward, IMARC Group expects the market to reach USD 20.3 Billion by 2033, exhibiting a growth rate (CAGR) of 4.4% during 2025-2033. The market is experiencing significant growth mainly driven by the technological advancements such as quantum dot enhancement and mini-LEDs, the rising preference for high resolution 4K and 8K displays along with the growing using flexible packaging. The expansion of application in various sectors including automotive, medical and consumer electronics is also contributing positively to the market growth.
The LCD backlight unit (BLU) is a key component in liquid crystal displays (LCDs) that provide the necessary illumination for the screen to be visible. It is responsible for evenly distributing light behind the LCD panel, ensuring optimal brightness and contrast. The BLU typically consists of several components. The primary element is a light source, such as light-emitting diodes (LEDs) or cold cathode fluorescent lamps (CCFLs). LEDs have become the predominant light source due to their energy efficiency, longer lifespan, and compact size. The light generated by the LEDs is then directed through a diffuser, which scatters the light uniformly across the LCD panel. A reflector is often placed behind the diffuser to enhance light efficiency by reflecting any stray light back toward the panel. In some BLU designs, additional components, such as light guides and prism films, are employed to enhance light distribution and control. Light guides help direct the light toward the entire display area, while prism films can be used to improve viewing angles and reduce glare. In recent years, BLUs have gained traction as they are an essential component for LCDs that directly impacts the overall display quality. It also determines the brightness, color reproduction, and contrast levels of the screen.
One of the primary factors driving the market is the widespread adoption of LCD displays in various applications such as televisions, computer monitors, smartphones, automotive displays, and signage systems. The demand for LCD panels directly translates to the demand for BLUs, as they are essential for illuminating LCD screens. Additionally, consumers are increasingly demanding high-quality displays with improved brightness, contrast, color accuracy, and energy efficiency. BLUs play a crucial role in meeting these demands by providing uniform and optimal illumination for LCD screens. Other than this, the automotive industry is witnessing a surge in the adoption of LCD displays for infotainment systems, instrument clusters, and head-up displays. This growth is fueled by factors such as the integration of advanced driver-assistance systems (ADAS) and the demand for interactive and immersive in-car experiences. As a result, the BLU market is experiencing significant growth due to the rising demand for specialized BLUs designed for automotive displays. Besides this, there is a continuous trend toward thinner and lighter displays across various industries, which is escalating the development of slim and compact BLUs that can fit into thinner form factors while maintaining high brightness and efficiency. Apart from this, the demand for BLUs that offer slim profiles and lightweight designs is fueled by applications such as smartphones, tablets, laptops, and portable consumer electronics. Moreover, continuous advancements in backlighting technologies have a significant impact on the BLU market. For instance, the development of more advanced LED backlighting solutions, such as local dimming and quantum dot technology, has enhanced the performance of LCD displays, thus driving the demand for corresponding BLUs.
