2017 The hottest properties of smart TVs, practicality can not bear to look straight!
In the first half of 2017, virtually all major smart TV manufacturers unveiled their flagship models for the year. These new releases typically emphasize HDR (High Dynamic Range), ultra-thin designs, OLED (Organic Light Emitting Diode) screens, and artificial intelligence as key features. It’s safe to say these four technologies and design elements represent the direction in which the smart TV industry is heading this year. However, how practical are these technologies and features for everyday users? In this article, we’ll take a closer look based on hands-on experience, evaluating the usefulness of these innovations using a five-star scale.
HDR:
High dynamic range technology enhances image quality by significantly boosting the contrast ratio of TVs. This results in richer color depth and improved visual fidelity. HDR has gained immense popularity partly because it caters to the human eye's preference for vibrant visuals, but also because it pairs well with 4K resolution, which focuses on improving picture clarity through higher pixel density. While 4K improves image quality at a hardware level, HDR optimizes it via contrast and brightness, offering a software-level enhancement.
Practicality:
At this point, the combination of HDR and 4K is becoming standard for mid-to-high-end smart TVs. However, the lack of HDR-compatible content remains a significant barrier. Most users still don’t have access to many HDR videos, making the practicality of this feature somewhat limited at the moment.
Ultra-Thin Design:
The trend toward ultra-thin TVs isn't just about aesthetics; it's also about engineering excellence and image quality. Ultra-thin TVs, often just a few millimeters thick, showcase advanced integration and manufacturing techniques. For instance, Xiaomi TV 4 and the Drunken A Series are notable examples with sleek, slim designs as a key selling point.
Practicality:
While a slimmer profile certainly gives TVs a modern look, the difference between a 10cm and a 1cm thickness in terms of wall-mounting is negligible. Additionally, achieving thinner designs often leads to lower yields and higher production costs, which can end up affecting the consumer price negatively.
OLED:
OLED technology, often referred to as the "organic light-emitting diode screen," has long been seen as a potential successor to LCD panels. Since its inception, OLED has been heralded for its superior image quality and deeper blacks compared to LCDs.
Practicality:
Despite being discovered nearly three decades ago, OLED hasn’t yet reached widespread popularity. The primary challenge lies in the immaturity of the production process, leading to high prices, especially for larger displays like TVs. Moreover, OLED screens tend to have shorter lifespans compared to LCDs. Consequently, for the average user, OLED technology remains impractical due to cost and durability concerns.
Artificial Intelligence Voice:
AI voice functionality combines speech recognition and natural language processing to enable TVs to understand and respond to user commands vocally. Features like playing, pausing, or switching channels are now commonplace in AI-powered TVs.
Practicality:
No matter how much manufacturers hype up AI capabilities, the reality often falls short. Current AI voice systems struggle with accurate speech recognition, especially in complex contexts or when dealing with regional accents. Furthermore, relying on voice commands feels cumbersome to many users who prefer traditional remote controls.
Summary:
The introduction of any new feature or technology in the TV industry signals potential advancements, but practical adoption takes time. For the average user, sticking to tried-and-tested configurations and technologies remains the wisest choice.
