Do not know OLED, come and see it
Although the focus of this article is primarily on OLED TVs, OLED technology has already found widespread application beyond the TV industry. Apple’s use of OLED screens in the iPhone 8 has now become common knowledge. As the most promising next-generation TV display technology, the increasing popularity of OLED TVs was evident at CES 2017. Sony’s release of the OLED TV A1E for the consumer market further strengthened the OLED camp. It’s time to get acquainted with OLED TVs.
1. What is OLED?
OLED stands for Organic Light-Emitting Diode, which translates to an organic light-emitting diode. This material was accidentally discovered by Professor Deng Qingyun of Chinese descent in 1979. While heading home, he realized he had forgotten something in the lab and upon returning, he noticed a bright light in the dark. It turned out to be an organic battery he had been experimenting with, leading to further research into OLEDs.
2. How does OLED TV differ from LCD TV?
Currently, LCD TVs dominate the market, with attention mistakenly directed towards LED, which refers only to the backlighting system while the screen material remains LCD. The most noticeable difference between OLED and LCD TVs is the presence or absence of backlighting. OLEDs emit light themselves due to their organic light-emitting properties, eliminating the need for backlighting, unlike LCDs which require a backlight unit to produce light.
3. What are the main advantages of OLED TVs?
OLEDs possess self-luminous properties, offering high contrast, fast response times, and a wide viewing angle, making them a strong contender for the next-generation display technology. Traditional LCD TVs face inherent issues such as light leakage and motion blur, which OLEDs can solve effectively. OLEDs excel in producing true blacks since their self-emissive pixels remain unlit during a black scene, creating an infinite contrast ratio compared to LCD TVs, which often suffer from backlight bleed and halo effects.
4. What are the drawbacks of OLED TVs?
Despite their advantages, OLEDs aren’t without flaws. One major criticism has been their low yield rates, susceptibility to image retention, and lifespan concerns. However, technological advancements have significantly improved these aspects. LG Display's production yield increased by 40% in 2016, reaching 85% in November, a remarkable achievement given LCD panels took a decade to reach similar yields.
5. OLED vs QLED vs ULED: What’s the difference?
Although these technologies share similar names, they are distinct and should not be confused. QLED TVs utilize quantum dot technology to enhance color gamut and accuracy, though current implementations are limited to backlighting LCD TVs. ULED is a proprietary image quality enhancement technology developed by Hisense, which combines local dimming and advanced processing to improve brightness, contrast, and color accuracy.
6. What OLED TVs are available today?
At CES 2017, several brands joined the OLED TV lineup. Sony reintroduced OLED TVs with its XBR-A1E Bravia 4K model, while Panasonic launched the second-generation EZ1000 OLED TV. LG unveiled multiple series, including the ultra-thin W7. Domestically, Skyworth showcased various OLED models, including the S9-I and S9D, and announced plans for a wallpaper TV. Other brands like Konka and Changhong have also ventured into OLED TVs.
7. Why don’t all brands offer OLED TVs?
The high cost of materials and production challenges previously made OLED TVs prohibitively expensive. Brands like Sony, which initially invested in OLED, suspended their efforts until recent advancements made OLED more viable. Technical expertise is crucial, and not every company possesses the resources to adopt this new technology.
8. Are OLED TVs worth purchasing now?
While OLED TVs remain costly, prices have dropped significantly since their initial release. Prices for 55-inch OLED TVs on e-commerce platforms range from $2,000 to $6,000 for 65-inch models. Given the convergence of prices with premium LCD TVs, OLED TVs are a reasonable choice, though waiting for further price drops might be prudent.
9. When will OLED panel dominance end?
For a long time, domestic OLED TVs relied heavily on LG Display's panels. However, the launch of China’s first independently developed OLED TV signifies a shift towards self-reliance in core components. This development will not only boost competition but also drive down OLED panel prices.
10. Will OLED TVs replace LCD TVs?
Though OLED TVs show great promise, it’s premature to predict their complete replacement of LCD TVs. OLED technology continues to mature, addressing past limitations and paving the way for broader adoption. Both technologies coexist in today’s market, with OLED representing the future potential of TV display technology.
This analysis provides insight into the current OLED TV landscape, highlighting both its strengths and challenges.
