The TV industry used to be the most popular industry in Japan. Externally, due to the impact of price wars of Korean and US brands, internally due to the sluggish local economy in Japan, most of the one-ticket manufacturers such as Toshiba, Hitachi, and Panasonic only stayed in the local business in Japan . In the domestic market, Japanese manufacturers who can maintain normal update iterations may save Sony. Moreover, the configuration of the sales models of the international version and the national bank version of Sony is basically the same. In the past two years, some flagship models, domestic licensed products have a certain price advantage over the international version.
· Resolution
Sony has clear grading in this regard. Among the 32-48-inch models, only 43X8000E is 4K resolution, and other models are 1366 * 768 (720P) or 1920 * 1080P level. Most of these models are positioning entry. From 49 inches, 4K resolution is used without exception. In other words, Sony's high-end models have completed the layout of 4K ultra-clear resolution. Although the current 4K video resources are scarce, Sony has been doing a good job in optimizing low-resolution signals. Whether it is a broadcast signal or a 1080P video signal, viewing on a 4K panel, the performance is still the same outstanding.
· Backlight
The liquid crystal is divided into a direct type backlight and a side entry type backlight. OLED does not have this problem because of its self-luminous properties. The direct-lit backlight provides the light source directly behind the LCD panel. The side entry type adds light sources from both sides of the fuselage. In terms of thickness, the side entry type is better than the direct type. In terms of picture quality, some direct-lit TVs are not as strong as mainstream side-entry TVs if they use fewer LED light sources and have fewer backlight areas. The core key is the number of backlight partitions. If there are enough direct-lit backlight partitions, the limit of picture quality is naturally higher.
Last year, Sony's high-end model Z9D's elite light control Pro technology was decentralized, divided into a standard version and an enhanced version. Another X9300E adopts a new design of side-entry backlight, and the light guide plate is added from top to bottom. The peak brightness and peak brightness maintenance time of both SDR and HDR images are higher than that of the X9000E with direct backlight.
· HDR
Full-name high dynamic range image, this technology can improve the performance of the picture, mainly reflected in the control of brightness, the contrast of the light and dark of different light is more directly reflected, the dark part is richer in details, and more accurate colors will bring More real feelings.
It should be pointed out that because HDR also has high requirements for the TV's backlight system, some low-end TVs can only achieve smart chip support for HDR, but the backlight system has difficulty supporting HDR's brightness requirements, and the effect is relatively poor. Most models currently on the market only support the lower threshold HDR 10 standard, in addition to the HLG broadcast signal standard and the highest standard Dolby Vision . The difference is mainly that there are different requirements on brightness level and color depth (bit).
· Dynamic compensation
The vast majority of the original signal is transmitted at 24 frames per second, and human eyes think that a smooth picture is 30 frames per second. In order to make viewing more comfortable, manufacturers will provide dynamic compensation technology, that is, adding white frames to the two frames to compensate, making the picture smoother and smoother. For those who like to play games or watch intense sports events, this function is very important. Sony named the dynamic compensation technology XR200, 400, 800, etc. Since most domestic and Internet brands do not have independent image quality optimization chips, all are processed by intelligent modules, and some CPUs have built-in MEMC dynamic compensation
· Image quality processing chip
Sony has already sold the LCD production line, which was a joint venture with Samsung, which means that Sony currently does not have the ability to produce large-size LCD panels, and all are obtained through external procurement. However, the quality of LCD panels is not much different now. The key to the quality of the image quality is the image quality processing chip, which is precisely Sony's biggest advantage.
Xunrui image processing engine Pro has a built-in database to reduce the occurrence of noise and burrs on the picture, and to calibrate the color to improve the clarity. At the same time, the resolution of low-resolution signals is optimized. For 4K HDR images, X1 processing chip is additionally configured, which is also divided into standard and advanced versions. It is used to enhance the performance of color and contrast, use the double-influence database, dynamically reshape the picture, and smooth 14bit gradient.
· Teri Charm Technology
In the W950A series launched in 2013, Sony has already used this technology. In principle, special materials are added to the LCD panel to change the performance of color gamut coverage. At the same time, with the addition of accurate color rendering technology, the color reaches its proper saturation without color cast, which brings rich Color gradation. It is very similar to the quantum dot technology currently promoted by Samsung.
· smart system
TV intelligence is the main direction of industry development. Although the system will become obsolete with configuration, the operating efficiency will gradually decrease. The advantage is that it brings convenience of obtaining applications and rich content of network video resources. At present, only the entry-level models of Sony retain non-smart TVs, and the mid-range models are equipped with Android-based smart systems. The MTK smart chip combination is used, which is usually a combination of 2GB running memory + 8G storage. The system's response speed can only be said to be basic pass. In terms of detailed UI optimization, it is not as good as domestic manufacturers do. There is no obvious shortcoming in the recognition of external devices and video decoding capabilities. In terms of network resource licenses, in addition to the previous Huashu TV, in 2017, it will gradually increase the proportion of more diversified Tencent video resources. Unlike other Internet brands that seize traffic entrances, Sony TVs have not been plagued by advertisements implanted in similar forms such as switching machines.
