On June 27th, the discussion of rivers and lakes - TV high-end tasting was held in Beijing. More than 30 netizens and experts from the forum, including experts in operation and TV engineering, discussed the form and characteristics of high-quality television. The whole discussion of tasting activities was carried out in accordance with the three major parts of the "Dispute between Disagreements", "Contestation of Quality of the Picture," and "Intelligent Controversy." They respectively analyzed the appearance, quality, and intelligence systems of TVs and helped them consume. Easy to buy quality television.
Curved surface display has long appeared in scenes such as amphitheatre and multi-screen splicing. However, with the increase of curved TVs in the past two years, the problem of surface and plane is getting more and more attention. Although the appearance of the two have their own merits, but in terms of visual experience, or surface is more suitable for human eyes. TV engineers introduced the use of curved technology on TV screens to create cinematic immersion, super-wide viewing angles and a comfortable visual experience.
Surface ergonomically more comfortable viewing
When we watch a flat TV, the distance between the glasses and each point on the screen is different. When you look at both sides in the middle, there is a situation where the viewing angle is too large, the contrast decreases, and the color shifts. Looking at the center point of the curved surface TV is closer to each part of the screen, which will reduce the distortion of the viewing angle. And the large-screen curved TV can often create a three-dimensional surround, creating an immersive feeling.
It is known that the human eye is a spherical structure, and the retina located on the back side of the eyeball also has a curved shape. The image of the circumscribed plane in the retina will be distorted due to the curved surface, and it needs to be processed by the brain to correct the posterior in order to feel the normal image. The curvature of the screen of the curved surface is closer to the human eye, and the projection of the screen on the retina will not be distorted. No visual processing is required, and the viewing is more comfortable.
Curved surfaces are not more stable than flat surfaces
Since the advent of curved television, there has been a kind of skepticism that curved LCD TVs are artificially curved, which will cause some bad influences on the quality and reliability of the screen. In fact, curved TVs are not subject to bending. It should be said that LCD TVs are natural songs. Senior TV engineers introduced that the LCD panel can be thought of as a piece of glass. It is inherently tough, especially when the thickness of the glass is only a few millimeters. When the area reaches a diagonal of 60 inches, the screen itself will naturally appear curved. The situation can be said to have curved properties. To make a curved TV, you only need to design the structure of the backplane first, so that the bending of the LCD backplane can be maintained, and there is no need to deliberately bend the glass.
The curved screen is not only bent, but also more stable than the plane. Just like a piece of paper, it is difficult to stabilize vertically in a plane state, and it is natural to stand in a curved state. For ultra-thin TVs, which are now popular in the market, if the workmanship and the reinforcement are not in place, after a period of use, the screen may be bent. The curved structure of the curved TV is inherently more stable and less deformable.
Focus 2: Quality Controversy
The principle of the backlight has always been to restrict the bottleneck of LCD TV picture quality improvement. Since the LCD panel itself does not emit light, the display of the images needs to rely on the illumination of light, which makes LCD TVs display, contrast, and contrast in the black field compared to self-illuminated display devices. Motion picture fluency, color and other aspects have been difficult to improve. Although the technology for improving the quality of LCD TVs emerges in an endless stream, most of them are adjusted from the image computing, color correction and other software aspects. It can be described as a temporary solution, and it is difficult to break through the bottlenecks of LCD TVs.
LCD TV backlighting has become the biggest bottleneck in image quality improvement
However, in recent years, technology that has broken through LCD TV barriers has finally emerged. ULED's multi-zone dynamic backlight control technology achieves contrast and smoothness comparable to that of self-illumination technology through flexible control of backlight. Quantum dot technology replaces traditional phosphors. LED backlight light source, the color purity and richness greatly improved, breaking the LCD TV gamut coverage limit.
ULED and OLED picture quality dispute
Since 2013, the debate between OLED and LCD technology has been fierce. Although organic self-luminous OLEDs have certain advantages in the principle of image development, after two years of development, the problems of low OLED yield and short life time have not been resolved so far. In addition to the high investment cost, OLEDs have not been popularized.
Compared with OLED TVs, Hisense ULED based on the liquid crystal principle provides better than 4 times the white field, 2 times the contrast, while providing twice the brightness of the visible range, the higher the level of picture detail. In terms of high color gamut, ULED TVs use nano-quantum dot technology, which increases the color performance range by 10% over OLEDs.
According to television engineers, the core of ULED technology is multi-zone dynamic backlight control, which significantly improves high peak brightness, black performance, contrast and layering. ULED TV divides the backlight into many independent controllable units. Through fine calculation and control, the backlight of each area will be adjusted according to the brightness and level of the screen. The bright and transparent part will enhance the backlight brightness of the area, while the black The field and shadow areas attenuate or turn off the backlight of the section, allowing high peak brightness, clean black performance, and higher contrast and gradation.
Quantum Dot Technology Breaks LCD Color Limits
As a relatively new topic in this year's TV industry, quantum dot technology is used by many brands in its latest flagship product. The so-called quantum dot is actually a kind of nanometer-sized particle that emits a single, pure light when irradiated with energy. Ordinary TVs rely on fluorescent powder to emit light. The spectrum of backlights is overlapping and mixed. The color performance is not pure enough and the color is difficult to control. Quantum-dot TVs, on the other hand, rely on nano-particles to emit light with a higher purity of color and a wider range of color gamuts that can express even richer colors.
It is reported that Hisense conducted research on the weak links of LCD TVs and finally developed ULED TV with multi-zone dynamic backlight control technology at the beginning of 2014. ULED technology has been developed to the second generation, and the display effect has been greatly improved compared with 1.0 and 1.5. Hisense's flagship XT910 series, which is newly launched this year, combines curved surfaces, ULEDs, and quantum dots, and is particularly good in image quality.
Focus 3: Smart Dispute
In the past two years, smart TVs have seen an explosive growth. Both market share and user familiarity have reached unprecedented heights. Among the products newly launched by major brands, there are few non-smart TVs. In particular, flagship products are equipped with the latest operating systems. It can be said that an outstanding smart system is an essential element of a good TV.
Many manufacturers have hit the "rich function" signs and tried to win by volume. However, like mobile phones and tablets, the user experience of smart TVs is the core competitiveness of the system. In the TV platform, users of different ages and occupations face only simple, easy-to-use, fast and efficient systems to gain more popularity.
System UI control simple and efficient is king
At present, most smart TVs use the design of a multi-page homepage. The icons are designed using a magnetic block or net format, and the overall effect is relatively simple. However, in order to simplify the content of each page, it increases the number of menus and pages, often watching a video from the main page to enter at least five pages, the steps are more cumbersome.
The VIDAA 3 smart operating system with four-button direct access and instantly switching to the main features adopts a homepage-less design, and provides users with four key functions such as live TV, network video, home media center, and APP. In what page, click one of the four buttons to directly switch to the specified function.
Functional and resource aggregation is more abundant
Hisense's VIDAA 3 system features a number of online video-on-demand platforms, and works with a number of video sites to create a legitimate, integrated video library for Hisense users. Operational experts introduced at the scene, Hisense VIDAA 3 gathers good-looking pages, adopts a shelf-like design, browses and finds videos more efficiently, and also more in line with the curve of the curved TV screen.
The converged film and television platform can provide more abundant resources
With the rise of TV shopping, Hisense also independently developed a shopping platform - enjoy the purchase, create a large-screen video shopping, product display in the form of video, the main concept of high quality and authentic, providing maternity and child products, South Korean first-line brand products, Unlike small-screen mobile phone shopping, large-screen shopping is not only more convenient for product viewing, but also increases the communication between users and their families.
Through cooperation with Tencent Games, VIDAA3 provides a multi-playing function with a high-quality game library. It also includes two game platforms, Love Game and Grape Game Hall, providing a wide range of game content. Compared to other systems that use a single gaming platform, there is a huge increase in the amount and quality of resources.
to sum up:
The items purchased for television are nothing more than appearance, quality, and system. Therefore, the tasting will have important guiding significance for television purchases based on the conclusions drawn from the “contestation of merits and demeritsâ€, “contention disputes,†and “intellectual disputes.†First of all, the curved TV is ergonomic, comfortable to watch, provides a shocking presence, and the structure is also more stable. In terms of picture quality, the combination of ULED and quantum dot technology can achieve superior image quality over OLEDs, while there are no issues such as low yield and short lifetime. In terms of intelligent systems, it is the most ideal form of smart TVs with a simple and efficient control and a rich resource aggregation platform.
As the leader in domestic TV, Hisense's recently launched flagship XT910 series will use advanced technologies such as curved surfaces, 4K ultra clear, ULED2.0, Quantum dots, etc., and is equipped with a minimalist operation and six major polymerization functions. The VIDAA 3 operating system has achieved industry-leading standards in terms of image quality performance, viewing experience and smart control.
