Today, with the rapid iteration of display technologies, emerging technologies such as OLED and Mini LED have seized the high-end market with their ultimate experiences. While LCD (liquid crystal display) has been a "veteran player" in the industry for decades, it has not withdrawn from the historical stage. Instead, it continues to play a core role in various fields. It has both mature and stable inherent advantages, but also faces many challenges brought by technical bottlenecks. In the competition between old and new technologies, it presents a distinct feature of "strong advantages, obvious weaknesses".
The full name of LCD is liquid crystal display. By utilizing the polarization characteristics of liquid crystal molecules and combining with a backlight, it achieves image display. After years of development, it has formed a complete industrial layout. Its advantages are particularly prominent in mass consumption, commercial display, etc. The core competitiveness of LCD lies in its mature stability and outstanding cost performance. Compared with emerging technologies such as OLED, LCD has a mature production process, which significantly reduces its hardware costs. Whether it is a thousand-yuan mobile phone, home TV, or office monitor, LCD products can meet the basic display needs of the general public at an affordable price, which is the key reason for its long-term dominance in the mid-to-low-end market.
The absence of burn-in risk and long lifespan have further consolidated the application advantages of LCD. Unlike OLED pixels that self-emit light and are prone to aging and burn-in problems, LCD relies on a backlight to emit light, and the liquid crystal molecules only regulate the passage of light. Even when displaying a fixed image for a long time, there will be no permanent imprint, especially suitable for commercial scenarios such as industrial monitoring, traffic guidance, and electronic price tags that require 7×24-hour continuous operation. At the same time, the lifespan of LCD screens generally reaches 40,000 to 50,000 hours, far exceeding the 10,000 to 30,000 hours of OLED. The durability is more in line with the usage requirements of outdoor and industrial environments.
In terms of display effect and scene adaptation, LCD also has irreplaceable advantages. Mid-to-high-end LCDs use IPS panels, which can achieve 100% sRGB color gamut coverage, with excellent color accuracy and stability, capable of meeting the color requirements of professional scenarios such as design and photography; its high brightness feature enables it to remain clear and visible in outdoor strong light and office windowed environments, which is superior to OLED screens that tend to darken easily in low brightness. In addition, LCD products are diverse, covering various panel types such as TN, VA, and IPS, with sizes ranging from a few inches to several tens of inches, and can be widely adapted to mobile phones, tablets, TVs, vehicle displays, industrial boards, and other types of equipment, with extremely wide application scenarios.
Despite its significant advantages, under the dual pressure of technological upgrading and market demand upgrading, the inherent shortcomings of LCD displays have become increasingly prominent, becoming a "stumbling block" for its breakthrough into the high-end market. The lack of contrast is the most prominent drawback of LCD. Due to its reliance on backlight emission, the liquid crystal molecules cannot completely block the light, resulting in a dark gray color when displaying pure black, and the mainstream products have a contrast ratio of only about 1000:1, far inferior to the theoretically unlimited contrast ratio of OLED. This leads to insufficient color gradation and less pure black representation when watching film and TV content in low-light environments, affecting the viewing experience.
The limitation of viewing angles and slow response speed further restrict the improvement of LCD experience. The viewing angles of LCDs of different panel types vary greatly. TN panels show significant color and brightness degradation when viewed from the side, even the relatively better IPS panels may also have slight color deviation when viewed from the side. The physical rotation characteristic of the liquid crystal molecules leads to a relatively slow response speed, which is prone to ghosting and residual images when displaying high-speed moving images, unable to meet the extremely high requirements for picture smoothness in professional e-sports and other scenarios.
In addition, the structural characteristics of LCDs bring problems such as thickness and flexibility. Due to the need for multiple layers such as backlight and liquid crystal layer, LCD screens are thicker and heavier compared to OLED screens. They are difficult to adapt to the trend of lightness and flexibility pursued by current mobile phones and foldable devices. This is also one of the core reasons why mid-to-high-end mobile phones have abandoned LCD and turned to OLED. At the same time, LCD has inherent problems such as uneven backlight and light leakage. When displaying pure black images in dark environments, white spots may appear at the edges or corners of the screen, affecting the visual experience. Moreover, this problem is limited by production processes and is difficult to completely avoid.
Industry analysts point out that the advantages and disadvantages of LCD displays are intertwined, determining their future market positioning. In the short term, in mid-to-low-end consumer electronics, commercial displays, industrial control, etc., LCD will still dominate due to its cost-effectiveness and stability advantages. However, in high-end mobile phones, foldable devices, and other fields that pursue ultimate experience, its shortcomings are difficult to overcome and will gradually be replaced by emerging technologies such as OLED. In the future, with the continuous optimization of LCD technology by enterprises like BOE, high-resolution, low-power consumption, and high-brightness LCD products are expected to further tap into the potential of niche markets and achieve continuous breakthroughs in competitive differentiation, forming a complementary and symbiotic market pattern with emerging display technologies.
