3D+ hard screen+smart LG LW9800 TV evaluation debut

IT 168 evaluation IPS hard screen panel can be regarded as the most recognized panel by consumers in TV industry in recent two years. Non-flash 3D TV can be regarded as the most advanced functional technology in TV at present, and smart TV can be regarded as a necessary condition for future TV. Now there is a TV product that combines these three excellent functional technologies. This TV is called LG LW9800.

Although LG LW9800 has not been officially launched, the author was lucky enough to get a 55-inch engineering prototype of this TV recently. From this engineering prototype, we can also appreciate the elegance of LG's latest flagship TV.

The width, height and thickness of LG 55LW9800-CA are/kloc-0 126.5x82.7x3.5cm Due to the side-entry LED backlight design, the thickness is small.

LG 55LW9800 adopts the traditional traceless injection crystal frame design. The 2.9cm frame feels very narrow against the 55-inch panel, but the overall design style lacks novelty.

The base of LG 55LW9800 is made of tempered glass, which has strong stability, but its overall mass is relatively large. Users need to find a sturdy table when placing it.

In terms of interface, LG 55LW9800 is divided into three parts, which are arranged on the side of the fuselage, the back of the fuselage and the back of the fuselage facing down. Interfaces on the side of the fuselage are: digital TV card slot x 1, USBx2 and HDMIx2. The interfaces on the back of the fuselage are: RS-232Cx 1, color difference component x 1, AVx 1, LANx 1, VGAx 1, audio x3, TVx2. The interfaces from the back of the fuselage downward are: color difference component x 1, AVx 1, LANx 1, VAX1,audio x3, and TVx2.

The LG 55LW9800 is equipped with dual remote controllers and dual 3D glasses.

LG 55LW9800 is a 3D smart TV, so the 3D glasses and smart TV remote control included in the accessories are essential.

In terms of remote control, the LG 55LW9800 is equipped with a conventional TV remote control and also comes with a special somatosensory remote control for smart TV. This somatosensory remote controller can not only perform simple routine operations, but also be used as a wireless mouse. Users only need to move this somatosensory remote control in the air to move the mouse arrow on the screen.

The somatosensory remote controller of LG 55LW9800 is also novel in appearance, and the curved design makes users feel very comfortable when holding it.

In terms of 3D glasses, since LG 55LW9800 adopts non-flash 3D technology, its 3D glasses are polarized 3D. The advantage of polarized 3D glasses is that they don't need power supply, so they are lighter and more comfortable to wear.

In addition, LG 55LW9800 also presented 3D lenses, which users wearing glasses can clip on their own glasses, avoiding the inconvenience of wearing two pairs of glasses.

The overall picture quality of LG 55LW9800 is excellent, but it is hard to say that it is top quality.

As a flagship TV, the performance of image quality is naturally better. The LG 55LW9800 has basically achieved this in terms of image quality. The dynamic definition of LG 55LW9800 has reached 1080 line, and the dynamic picture processing is very smooth, with almost no tailing phenomenon, which is very suitable for watching sports programs.

In contrast, the author measured that the ANSI contrast of this TV is 2 10: 1, which is an excellent level in LCD TV. The details are very delicate, the picture transition is very natural, and the performance of high-definition movie pictures is in place.

The color gamut of LG 55LW9800 is 77%. Although it is above the average level in LCD TV, it cannot be called the top level for a high-end flagship TV. Judging from the performance of the actual picture, the color of LG 55LW9800 is gorgeous, and the green picture is slightly yellow, but the overall feeling is quite comfortable.

When LG 55LW9800 is connected to PC through HDMI interface, it can be displayed point to point, with more accurate color reproduction and no color cast.

The LG 55LW9800 adopts IPS panel, and one of the advantages of IPS panel is its large viewing angle. I did see this from the actual performance of this TV, and its viewing angle is close to 180? .

It may be because of the engineering prototype. The light leakage of LG 55LW9800 under full black screen is better than that of glasses. I hope the product can be improved when it is officially launched.

▲ There is light leakage at the four corners.

LG 55LW9800 has exquisite HD picture and gorgeous cable TV.

From the data performance on the previous page, we can easily see that the overall performance of the image quality of this LG 55LW9800 is still excellent. Let's feel the picture quality performance of this TV more intuitively from the high-definition renderings.

From the renderings, we can see that the picture color of LG 55LW9800 is very gorgeous, and the outstanding contrast makes the picture transition more delicate and the details more clear. The overall color performance of LG 55LW9800 feels warmer, which is more suitable for China people's preference for color temperature.

Cable TV signal is still the main signal source we use to watch TV programs, so the author also tested the effect of this LG 55LW9800 cable TV signal.

As can be seen from the cable TV renderings, although the picture definition is slightly poor due to the low resolution, the overall color is as gorgeous as the high-definition renderings.

Non-flash 3D viewing is more comfortable. Up close, it looks jagged.

Non-flash 3D is a 3D technology jointly promoted by several major TV manufacturers such as LG, and its essence is the same as the polarized 3D or polarized 3D technology we introduced before. LG 55LW9800 This TV adopts non-flash 3D technology.

The advantage of non-flash 3D technology is that users will not feel flicker when watching it, so they get the name of non-flash 3D, and the 3D glasses used do not need power supply, so they are light in weight and more comfortable to wear. However, this technology is not perfect. In principle, polarized 3D technology divides images into two groups: vertically polarized light and horizontally polarized light, and then uses polarized lenses with different polarization directions on the left and right sides of 3D glasses, so that people's left and right eyes can receive these two groups of images, and then synthesizes stereoscopic images through the brain. So its resolution and brightness will be halved. The following four pictures are real shots of 3D images.

▲90? Deflection to watch 3D playback effect

From the 3D playback renderings of real shots, since the brightness of this LG 55LW9800 has reached 499.5cd/㎡, the attenuation of brightness has little effect on the image quality. But if you watch it at close range, the picture will have a slight sawtooth feeling.

In addition, LG 55LW9800 also supports the function of converting 2D to 3D, which alleviates the problem of insufficient 3D film sources to some extent.

▲ Support multiple 3D modes

The USB playback of LG 55LW9800 does not support RMVB format.

USB playback is an indispensable function of TV set at present, but the video format support of different TV sets is different. This LG 55LW9800 supports ts, MKV and MP4 video playback, but unfortunately it does not support the common RMVB format video. In addition, this product does not support audio tracks in TrueHD and DTS formats, so users still focus on watching when choosing to play videos.

Smart TV has a simple interface and is easy to apply and install.

Next, the author will introduce the biggest feature of this TV, the smart TV function. When it comes to intelligence, what do you think of? In fact, the so-called intelligence and? Smart phone? In the room? Smart? It is the same, that is, the product itself is an open platform, and users can install some interesting applications according to their own preferences.

Smart TV, like smart phone, is also divided into different system platforms. The intelligent platform adopted by this LG 55LW9800 is called smart TV platform. The author understands that LG is using this platform, and Sharp and Philips are also using this platform to develop smart TVs.

As a consumer, I think most people should be very concerned about the practicality of smart TV. If smart TV is just a gimmick, few people are willing to spend extra money to buy such TV. Below, the author will experience this LG 55LW9800 smart TV from the perspective of a consumer.

▲ Smart TV main interface

Open the main interface of smart TV, and the simple and clear design is pleasing to the eye. The main interface can be divided into four parts, namely the picture played by the current video source, the network video menu bar, the App library recommendation bar and the bottom row of shortcut items. As a smart TV, what naturally attracts me most is the application part. I clicked on LG Apps and first entered the application library. Enter the application library, where * * * is divided into six tabs: All, Games, Entertainment, Life, Education and News/Details. Each tab corresponds to a different type of application.

After browsing all the applications, I chose a software installation called RELAX. In the installation interface, I can see the introduction, version, size, rating and other information of this software. At the same time, I saw that the storage space of this LG 55LW9800 is 236 mm.

Application Experience of LG 55LW9800 Smart TV

After installing several product applications, I plan to experience them one by one.

Recently, many friends around me prefer to discuss horoscopes. Under their influence, I also got into the habit of looking up constellations every day. Turn on LG Smart TV before going out every day? Horoscope? It is necessary to read the horoscope every day.

It is common to go to a strange place. How do you usually solve it? Turn on the computer to check the map or use the mobile phone map to check it? With LG Smart TV, you can do it easily. Open it? I want a map? Application, a map with a big picture is presented in front of you.

LG Smart TV's post-application production is guaranteed.

A platform, no matter how excellent, can not be separated from rich applications. In the smart phone industry, Apple's ios and android systems are popular not only because of their powerful system platforms, but also because of their rich applications. The same is true for the smart TV industry. In the early stage of smart TV, the application of each platform is inevitably not rich enough, and the development of later programs is the key to the success of this platform.

Just recently, LG, Sharp and Philips announced that they would jointly create a set of software development tools for their smart TVs. This development tool will be based on open source languages such as HTML5, CE-HTML and HbbTV. Developers will receive a beta version of the tool in early 10, and the official version will be released at the end of this year. Successful examples of forming alliances through strong alliances are not uncommon. Compared with companies behind closed doors, alliance forms are easier to promote the growth of a new product. I believe that the application of this LG smart TV will be more abundant in the future.

Comprehensive performance and outstanding features are worth looking forward to.

In terms of appearance, the LG 55LW9800 has a small thickness due to the side-entry LED backlight design, which is very suitable for both wall hanging and desktop. However, the design of seamless injection crystal frame is a bit outdated and not innovative enough.

In terms of performance, the dynamic clarity and contrast of LG 55LW9800 are top performance, so it will have better performance for sports programs and high-definition movies. 77% color gamut restoration is not excellent for flagship models, but it will not be shameful in a high contrast background. The actual performance of warm colors is very pleasing to the eye.

In terms of functions, LG 55LW9800 not only has common functions such as USB playback, network video and 3D, but also is a smart TV. Among them, non-flash 3D is more comfortable to use, and it will not cause fatigue after watching for a long time. Random 3D glasses are more intimate for friends who wear glasses. Smart TV, as the hottest topic in the TV industry this year, has been receiving much attention. This LG 55LW9800 adopts a smart TV platform, and users can install rich applications.

Through this evaluation, I believe everyone has a certain understanding of this LG 55LW9800. As the flagship model of LG, LG 55LW9800 has very comprehensive performance, excellent picture quality and complete functions, covering almost all the best-selling technologies and functions in the TV industry. Judging from the current price of the 55-inch flagship TV on the market, the release price of this TV should be between 20,000 and 25,000. If the price can be reduced below 20 thousand in a short time, it will be a very suitable product for high-end users.
