持分请教：关于LCD电视请教3D,高清，LED等意思

snowbird

现在的电视机，看说明五花八门，价格也是五花八门。请给我这个很落伍的人士科普一下？
LCD, LED, 3D,等等

持分请教。
另请推荐：中等尺寸的液晶电视中比较不错的牌子。或者某个牌子不错的系列。
多谢多谢。

led更轻更薄更省电，当然也更贵

LCD vs Plasma vs LED
Which is better to buy? LCD, Plasma, or LED TV? It can be a difficult decision, and one not helped by having to decide between remarkably similar features and qualities. But let us take you through some of the qualities of each that might make your choice a little easier.

Plasma technology was originally invented in monochrome in 1964. However, it has come a long way since then - developing into the key competitor in today’s flat-screen TV market. Plasma screen technology is basically many tiny cells containing gases, all cushioned between two layers of glass. These gases become plasma when electricity is applied, eventually emitting light to transmit your favourite shows and games.

LCD technology, however, involves a series of filters over a layer of liquid crystal molecules. This is contained within two glass plates. The images you see are controlled by the filters which twist when electricity is applied to allow fluorescent light through in varying degrees.

LED technology is the latest emerging technology in flat screen TVS. LED TVs are known as a much more energy efficient and compact option than LCD TVs, offering screens only 1 inch thick. In fact, LED TVs are composed of a hybrid of LCD technology, with LED backlighting instead of fluorescent backlighting, bringing brighter contrast, more powerful colours and deeper blacks. LED TV technology is also incredibly energy efficient, currently using 40% less energy than many LCD models.

Plasma screens are seen as bulkier or heavier than LCD and LED screens, though some manufacturers have introduced thinner models. LCD and LED screens are generally thinner than Plasmas, making them easy to mount on a wall. Plasmas do well in terms of contrast and ‘blackness’, in that they are more capable of producing a darker black than LCD screens. While LCD screens have made leaps and bounds with this problem, their darkest blacks do not hold up when looking at your picture from the side, or off axis. However, the technology used in LED TVs means that even the improved LCD colour is enhanced, meaning a much bigger gamut of colours and blacks in every image.

LCD and LED screens hold up in terms of glare on the screen, whereas Plasma TVs can face problems with it. However, some Plasmas are being produced with anti-glare glass installed to reduce this. Plasma screens also face a problem of image burn – if you leave a bright image paused on your monitor for a long period of time, that image will be imprinted on your TV. Though this fades with time, LCD and LED TVs face no such problem. Not only this, but LCDs are also designed to have more connectivity with PCs than Plasmas do.

Plasmas also win with response times, meaning that the image is received and broadcast slightly faster than LCDs. This makes Plasmas a good choice if your preference is high speed action, or sport.

Besides all of this, LCD, LED and Plasma screen TVs have several points in common. All are capable of delivering up to 60,000 hours of performance, or 8 hours per day for 20 years. There are many, many models available at similar prices and sizes. With many of the above mentioned problems, there are just as many models designed to combat the issues – meaning the best you can do when buying is to come to a store and check out the physical attributes of your potential purchase.

3D要解释的。
是否要带眼镜， 是否电视节目出来也是3D效果了。之类的。买有3D效果的，是否不值得。当前来说。

不好意思。我点评分要去加分，怎么出来了个报告？

因为你手抖了。

尺寸：越大越好
面板类型：Plasma是等离子，LCD是液晶，LED是发光二极管当背光的LCD。
Plasma动态画面表现好，但是耗电量大，机身厚。显示固定画面久了有点残留的影子。价格很便宜了，慢慢淘汰中。
不过发现LG的新一代plasma电视耗电量显著下降。机身也很薄，适合放在客厅里看球赛，看电视。
LCD也逐步淘汰中，背光是灯管，画面偏暖色。
LED背光比较白，画面冷艳，颜色更准确，稍贵一点。
分辨率：像素点，越高越好，HD是高清分辨率1280x720，FULL  HD全高清是1920x1080，达到标称分辨率的视频显示效果最好，点对点显示。
倍频技术：LCD和LED用的。倍频低的动态画面有拖尾，100hz的电视可以让动着的东西没有拖影，更清晰。
3D：不是很清楚，大概屏幕上同时显示两个视角的画面，观看者需要戴眼镜，让左右眼分别看到不同的画面，立体感就出来了。
亮度会显著下降，有人看久会头晕。效果肯定没有imax电影院好，自己看看是否喜欢吧。

我觉得性价比最好的应该是LG的电视，其次松下。品质不好说，现在大屏幕电视生产已经很成熟了，坏了是运气问题。
选电视要眼见为实，去电器店看，看好了要报价。然后去另外一家砍价，跑3家就差不多买到合理价格了。
