汉英对照:
Chinese-English Translation:

电视参数主要有屏幕类型,屏幕是一台电视最主要的部分,占电视总成本的80%。电视屏幕直接影响着画质的优劣,是衡量电视质量的核心部分。其次是屏幕大小应该根据观看距离来定,三米左右的距离观看50英寸以上的电视。最后就是分辨率当然越高越好。

TV parameters mainly include screen type, and screen is the most important part of a TV, accounting for 80% of the total cost of TV. TV screen directly affects the quality of the picture, and it is the core part to measure the quality of TV. The second is that the screen size should be determined according to the viewing distance. You can watch more than 50 inches of TV at a distance of about three meters. Finally, of course, the higher the resolution, the better.

如果你在卧室或者比较小的客厅,那么选择 42 英寸或者更小的电视才是更好的选择。电视分辨率是屏幕图像的精密度,是指电视所能显示的像素有多少。现在市场中最为火热的莫过于 4K 超清分辨率的电视了,它能够提供 3840×2160 的四倍于 1080P 的分辨率,能够显示电视画面中更多的细节,显著提升画面的清晰度。

If you’re in a bedroom or a small living room, a 42 inch or smaller TV is a better choice. TV resolution is the precision of screen image, which refers to the number of pixels that TV can display. Now the most popular TV in the market is 4K ultra-high resolution TV, which can provide 3840 × The resolution of 2160 is four times that of 1080p, which can display more details in the TV picture and significantly improve the clarity of the picture.

分辨率:分辨率是衡量液晶电视性能高低的一个重要标准,目前市场主流的分辨率参数主要是 1366×768 和 1920×1080。高清平板电视机在水平和垂直方向上的清晰度要高于 720 线,简单来说就是真正的高清平板电视机必须要满足分辨率高于 1366× 768 这一条件。

Resolution: resolution is an important standard to measure the performance of LCD TV. At present, the mainstream resolution parameter in the market is 1366 × 768 and 1920 × 1080。 The definition of HD flat panel TV is higher than 720 lines in horizontal and vertical direction. In short, the resolution of real HD flat panel TV must be higher than 1366 lines × 768.

响应时间:响应时间也很重要,它会决定在显示高速动态画面时是否会出现模糊和拖尾现象,购伙伴的专家提醒大家:目前主流的 8 毫秒响应时间基本可以满足使用要求。一般来说反应时间越快,液晶电视就会越少出现拖尾、残影现象。最好在购买前看看实际播放动作片的效果。

Response time: response time is also very important. It will determine whether there will be blurring and tailing when displaying high-speed dynamic pictures. Experts from purchasing partners remind us that the current mainstream 8 ms response time can basically meet the use requirements. Generally speaking, the faster the reaction time, the less trailing and residual shadow will appear in LCD TV. It’s best to see the actual effect of playing action movies before buying.

亮度、对比度:其实可以直接忽略厂商提供的亮度和对比度参数,直接以自己的目测感受为主,方法为在 5 米以外的距离,查看屏幕显示亮度和对比度,注意一些黑暗场景中的细节表现,多做几款产品对比。

Brightness and contrast: in fact, you can directly ignore the brightness and contrast parameters provided by the manufacturer, and directly focus on your own visual experience. The method is to check the brightness and contrast of the screen display at a distance of 5 meters, pay attention to the details of some dark scenes, and do more product comparison.

尺寸:要了解摆放电视机的房屋大小,从而确定应该选购多大尺寸的电视。比如 42 寸液晶电视最佳的收视距离是 2.5 米到 3.3 米,47 寸液晶电视的是 3 米到 4 米,55 寸液晶电视的是 4.5 米到 5.5 米,这是一个可以根据自己家里面实际情况来选择电视机尺寸的大小。

Size: to understand the size of the house where the TV is placed, so as to determine what size of the TV should be purchased. For example, the best viewing distance of 42 inch LCD TV is 2.5 meters to 3.3 meters, that of 47 inch LCD TV is 3 meters to 4 meters, and that of 55 inch LCD TV is 4.5 meters to 5.5 meters. This is a TV size that can be selected according to the actual situation in your home.

HDMI 接口:HDMI 接口是可以同时传输音频和视频信号的数字接口,它不但可以简化连接,减少连线负担,而且可以提供庞大的数字信号传输所需带宽。强调这一接口的重要性主要在于现在新的和未来的碟机、电脑、家庭影院等设备,都会积极采用这一接口,而应用这一接口来与这些设备连接,无疑可以获得最好的效果。

HDMI interface: HDMI interface is a digital interface that can transmit audio and video signals at the same time. It can not only simplify the connection and reduce the burden of connection, but also provide huge bandwidth for digital signal transmission. Emphasizing the importance of this interface lies in the fact that the new and future CD players, computers, home cinemas and other devices will actively adopt this interface, and the application of this interface to connect with these devices will undoubtedly achieve the best results.

坏点:在购买之前一定要仔细地观察屏幕上是否有亮点和暗点。可以在白屏的时候寻找暗点,黑屏的时候寻找亮点,购伙伴的专家告诉大家一个辨别坏点的小窍门:在全绿屏的时候找暗点,全蓝屏的时候找亮点,一旦有亮点或者暗点非常容易就看出来了。另外,最好在付钱之前就坏点问题和商家达成协议,写进合同。

Bad points: before buying, be sure to carefully observe whether there are bright and dark spots on the screen. You can look for dark spots when the screen is white and bright spots when the screen is black. Experts from partners tell you a trick to identify bad spots: look for dark spots when the screen is all green and bright spots when the screen is all blue. Once there are bright spots or dark spots, it’s very easy to see them. In addition, it’s better to reach an agreement with the merchant about the bad points before paying, and write it into the contract.

音质:各个厂家在这方面都有自己的卖点,什么 Surround 三维空间环绕声、SRS 虚拟环绕声、BBE 立体声音效、分频扬声器、DDAS 数字动态声谷、各式各样的音频解码芯片和引擎,可谓花样繁多。但是这些东西除了部分专业人士和音乐发烧友可以看懂之外,对普通的消费者并没有带来实际的意义。无论其炒作得如何热闹,其实实际效果基本是大同小异。所以消费者挑选时应该拿定主意,听一听音质好坏最关键。

Sound quality: each manufacturer has its own selling points in this aspect, such as surround 3D space surround sound, SRS virtual surround sound, BBE stereo sound effect, frequency dividing loudspeaker, DDAs digital dynamic sound Valley, various audio decoding chips and engines, which can be described as various. But these things in addition to some professionals and music enthusiasts can understand, the ordinary consumers did not bring practical significance. No matter how lively the hype is, the actual effect is basically the same. So consumers should make up their mind when they choose to listen to the sound quality.

遥控器:挑选时最容易被忽视的就是遥控器。好遥控器回弹力强。好的遥控器入手给人很敦实的感觉,而差的遥控器通常显得很轻,其原因除了里面的元件做工实在以外,就是外壳采用的材质不同。遥控器上下外壳的结合紧密程度上,好的结合非常紧密,差的结合疏松。好的按键只要用适当的力度就可以按下,弹性好,回弹有力度。最后还可以敲敲听声音,差的遥控器听起来里面像是空的,而好的遥控器由于做工实在,听起来像是实心。

Remote control: the most easily overlooked is the remote control. Good, the remote control has strong resilience. A good remote control gives people a very solid feeling, while a poor remote control usually appears very light. The reason is that in addition to the actual workmanship of the components inside, the material used in the shell is different. The combination degree of the upper and lower shell of the remote control is very close, the good combination is very close, and the poor combination is loose. A good key can be pressed with proper force, with good elasticity and strong rebound. Finally, you can tap and listen to the sound. A poor remote control sounds like it’s empty, while a good remote control sounds like it’s solid because it’s really made.

设计:选择液晶电视机还需要关注人性化设计是否与自己使用需求合拍。如平板电视机外观与家居设计的融合眼下受到前所未有的关注,外形也不能不考虑。再比如像主动背光调节,无线耳机接收等功能都会影响到使用感受。

Design: the choice of LCD TV also needs to pay attention to whether the user-friendly design is in line with their own needs. For example, the integration of flat-panel TV appearance and home design has received unprecedented attention, and the appearance can not be ignored. For another example, functions such as active backlight adjustment and wireless headset reception will affect the user experience.

特别是音箱的设计尤其重要,因为听不好一定就会影响看的效果。与常见的传统两侧立式音箱设计相比,卧式渐渐开始流行。由于目前 16∶9 的液晶屏已经是液晶发展的主流,这使得液晶电视在纵向延伸了液晶电视机身长度,卧式液晶电视音箱设计使得 16∶9 显示屏的液晶电视整体布局更加协调。另外卧式音箱设计有利于人声对白的表现,让人更身临其境,其作用类似于环绕声系统中的中置音箱。在环绕声系统中,70%的声音都是发自中置音箱。

In particular, the design of the speaker is particularly important, because not listening well will certainly affect the effect of watching. Compared with the common design of traditional vertical speakers on both sides, horizontal speakers are gradually becoming popular. At present, the 16 ∶ 9 LCD screen is the mainstream of LCD development, which makes the LCD TV extend the length of LCD TV body longitudinally. The design of horizontal LCD TV speaker makes the overall layout of 16 ∶ 9 LCD TV more coordinated. In addition, the horizontal speaker design is conducive to the performance of human voice dialogue and makes people more immersive. Its function is similar to the center speaker in the surround sound system. In the surround sound system, 70% of the sound comes from the center speaker.

选择电视的 5 个技巧

Five tips for choosing TV

1.看画质,自己对电视的效果主观上的感觉,毕竟电视是用来看的,你看的时候有什么感受,清晰还是不清晰,这个是最终要的。

1. Look at the picture quality, my subjective feeling about the effect of TV. After all, TV is used to watch. What do you feel when you watch it, clear or not clear? This is the final thing.

2.看功能,电视现在炒作的很厉害,LED 电视 微博电视 云电视 等等。USB 网络电视电影播放等等。这些功能,有哪些是你真正想要的,我个人认为,LED 电视,省电,这个是比较好的。

2. Watch function, TV is now highly hyped, LED TV, microblog TV, cloud TV and so on. USB network, TV, movie and so on. These functions, which are you really want, I personally think, LED TV, power saving, this is better.

3.价格,价格因素没有人不考虑吧。

3. The price, the price factor nobody does not consider.

4. 所谓的屏指标,其实完全可以忽略,除了一点(分辨率)。全高清和高清,分辨率差了很多。还是值得的。至于软屏还是硬屏完全没有必要考虑。

4. The so-called screen index can be completely ignored, except for one point (resolution). Full HD and HD, the resolution is much worse. It’s worth it. As for the soft screen or hard screen, there is no need to consider.

5.其他的就是接口吧,有几个 HDMI 接口,对于追求品质的人来说 HDMI 是必备的,当然也许有时候需要三个以上。

5. The other is the interface. There are several HDMI interfaces. HDMI is necessary for people who pursue quality. Of course, sometimes more than three are needed.
