As we all know, the core component in the television industry is the panel. Currently, the three major types of panels used in TVs are OLED, quantum dot, and LCD/LED liquid crystal panels. When it comes to the future of TV panels, which will dominate—OLED, quantum dots, or LCD? To answer this question, we first need to understand what OLED, quantum dots, and LCDs are, their differences, and their respective strengths and weaknesses.
OLED (Organic Light Emitting Diode) screens are made using organic electroluminescent diodes. Unlike traditional LCDs, OLEDs emit light on their own, eliminating the need for a backlight. This results in higher contrast ratios, thinner designs, wider viewing angles, faster response times, and greater flexibility in panel construction. Additionally, OLEDs work well across a wide temperature range and offer simpler manufacturing processes. The potential of China’s OLED industry is promising, and domestic players are actively working to enhance their technological capabilities. However, challenges remain in the domestic supply chain and the support infrastructure, which creates obstacles for many manufacturers.
Quantum-dot TVs utilize quantum dot technology for backlighting, making them a variant of LCD TVs. What sets them apart from conventional LCDs is the superior backlighting, which leads to noticeable improvements in picture quality, energy efficiency, and environmental friendliness. This has positioned quantum-dot TVs as a key direction for the future development of LCD TVs within the industry.
The third type, LED/LCD panels, are also widely used. LCD (Liquid Crystal Display) works by sandwiching a substance between a solid and liquid state, with molecules arranged in a specific order. When heated, this substance becomes transparent, and upon cooling, it forms a cloudy solid. In terms of visual appeal, LED screens provide softer colors, with the center and edges of the screen having similar light intensity, making them ideal for prolonged gaming sessions. On the other hand, LCD screens have higher light intensity, which might cause some eye strain over time. Yet, they display colors vividly, making them better suited for movie viewing. Despite slight variations in light intensity across the screen, the overall impact is negligible.
One of the standout advantages of LCD panels using LEDs as backlighting lies in their longevity, energy efficiency, and environmental friendliness. For instance, LED backlight systems can last up to 100,000 hours, equivalent to continuous use for 27 years at 10 hours per day. They consume 48% less power than traditional CCFL LCD panels and do not contain mercury, a harmful element present in CCFLs. Furthermore, LED backlighting supports 100% NTSC color gamut coverage, ensuring vibrant and accurate colors.
While the debate about the future of TV panels often centers around OLED versus quantum dots, the real competition is between OLED and LCD/LED panels. Most OLED panels are monopolized by global giants like Samsung and LG, leaving domestic industries somewhat constrained. In contrast, Sharp, once a leading LCD panel manufacturer, now benefits from its advanced technology under Foxconn's ownership, positioning it as a domestic competitor.
To compare OLED and LCD panels directly, OLEDs eliminate the backlight and liquid crystal layers, relying instead on organic self-luminous sources, allowing for thinner designs. In 2014, LG showcased this advantage by launching a 0.4 cm-thick OLED TV. Similarly, Sony introduced an ultra-thin LCD TV in 2015, just 0.09 cm thicker than the OLED model. However, pricing remains a significant factor, with OLED TVs costing roughly three times more than comparable LCD models. Consumers tend to lean toward LCD TVs due to their affordability and reliability.
Despite the high cost of OLED panels, they do offer unique advantages, particularly in flexibility and design innovation. OLED TVs can bend into various shapes, offering creative opportunities in both aesthetics and functionality. However, LCD panels continue to dominate due to their cost-effectiveness, durability, high brightness, excellent color reproduction, and energy efficiency. Sharp’s LCD-based technology represents one of the leading examples of this trend. It is anticipated that LCD panels will soon become the dominant choice for TV manufacturers and consumers alike.
