In 2023, the OLED market has become a major talking point. In the smartphone sector, Apple finally launched its first OLED-screen iPhone, while in the TV industry, Sony made a strong return to OLED with the launch of the A1 model at the start of the year. As these two industry giants push forward, the belief that "OLED is about to replace LCD" has grown louder. However, not everyone is convinced. Sharp, known as the "father of LCD," has taken a different approach by launching several flagship LCD models to defend its legacy.
To understand which technology will dominate the future, we tested two top-tier TVs: the Sharp AQUOS SU875A (LCD) and the Sony KD-65A1 (OLED). Both are flagship models from their respective manufacturers. How do they perform in terms of image quality?
**Black Level Performance: OLED Leads, but Sharp Surpasses Expectations**
The fundamental difference between LCD and OLED lies in their light-emitting properties. LCD panels rely on backlighting, typically using LED lights around the screen. These lights reflect off a backlight board and pass through polarizers, which can lead to light leakage or uneven brightness. In contrast, OLEDs are self-illuminating. Each pixel emits its own light, allowing for true black levels when pixels are turned off.
When displaying a pure black image, the SU875A showed impressive performance. Despite being an LCD, it managed to maintain a deep and uniform black without noticeable light leakage. The Sony A1, with its OLED panel, also delivered excellent black levels, but the SU875A proved that high-end LCDs can still offer exceptional performance.
**Static Comparison: Details Are Almost Indistinguishable**
Both TVs use 4K panels, and when testing high-resolution images, the differences were barely visible to the naked eye. The SU875A even features a Japanese-imported 4K screen, emphasizing its premium build. When looking at textures and edges, both TVs performed exceptionally well, preserving fine details with clarity.
However, the SU875A had some minor issues with viewing angles. When viewed from an extreme angle, color shifts occurred, though this is common for most LCD TVs. The Sony A1, on the other hand, maintained better color consistency even at wide angles.
**Color Performance: Sony Is More Vibrant, Sharp Offers Customization**
In terms of color accuracy, Sony’s A1 displayed more vibrant and intense colors, especially in red and blue tones. This made the image look more vivid and visually appealing. The SU875A, while slightly less saturated, offered a brighter and more natural appearance, particularly in scenes like nature and flowers.
Sharp also provided multiple color modes and manual adjustment options, giving users more control over the picture. Both TVs showed similar grayscale performance, indicating that neither was significantly better than the other in this aspect.
**Dynamic Video: SU875A Excels in Motion Handling**
During dynamic video playback, the SU875A outperformed the A1 in motion handling. Thanks to its MEMC chip, the SU875A reduced motion blur and improved clarity in fast-paced scenes. The A1, while offering sharper images, sometimes over-enhanced details, leading to overexposure and loss of texture.
**HDR Performance: A1 Shines, But SU875A Compensates Well**
Both TVs support 4K HDR, but the A1 demonstrated superior HDR performance, with better shadow detail and overall brightness. However, Sharp’s “Huang Cai†technology compensated for non-HDR content, enhancing brightness, contrast, and dark details. This makes the SU875A a practical choice for everyday viewing, where HDR content is limited.
**Conclusion: Sharp’s Practical Approach Wins the Day**
While the Sony A1 offers advantages in black levels, HDR, and viewing angles, the Sharp SU875A proves that LCD technology is far from obsolete. With advanced hardware and software optimization, the SU875A delivers a competitive image quality that rivals OLED in many aspects. Its practical and mature approach makes it a strong contender in the current market.
