LCD TV is now the leader of TV products, in the TV market occupies an absolute advantage, is the first choice of many families TV products. But LCD TV product types are very much, in the end which one is the most cost-effective and the most satisfactory? Don’t worry, before understanding what kind of good LCD TV, we should first know what LCD TV is good to make the corresponding measurement, let’s take a look at it.
First, what is LCD TV?
Liquid crystal is a kind of substance between solid state and liquid state. It is an organic compound with regular molecular arrangement. If it is heated, it will appear transparent liquid state, and if it is cooled, it will appear cloudy solid state of crystalline particles. It is because of this property that it is called liquid crystal. Liquid crystal displays (LCDS), whose molecular structure is similar to that of fine matchsticks, are called Nematic LCDS, and LCDS made from such LCDS are also called LCDS. LCD TV, on the other hand, adds voltage to the liquid crystal between two sheets of glass to reproduce the picture through the changes of molecular arrangement and twists and turns. The screen creates the picture through the collision of electron groups and forms the picture through the perspective reflection of external light. LCD TVS are now within the reach of most families, and as prices get lower and lower, many people want to replace their old TVS.
Two, LCD TV how to choose?
1. Test the color accuracy of the TV
One concept that is easily confused with gamut is the color depth of the TV panel. The mainstream LCD panel is each primary color of 8bit color depth, and some day manufacturers launched 10bit LCD panel driving technology, so there are always people will think that high color depth brings a wider gamut, and this is exactly a mistake. The benefit of having a higher bit is that the accuracy of the colors is greatly increased without increasing the gamut of the display device. Because flat-screen TVS are all digital processing circuits, each color will be represented by a variety of binary values. Take 8bit as an example, an 8-bit binary number can represent a total of 256 values from 0 to 255, that is, a certain color has only 256 levels of difference, while using 10bit, the value range will be extended to 0 to 1023, can describe 1024 color levels. So for the same original signal, using higher color depth is equivalent to describing the original signal in a more precise order of magnitude, without changing the original signal itself. Therefore, high color depth can only make the display device more accurate color performance, the transition between colors smoother, but has no effect on the color gamut.
2. Light control is really important
The structure of LCD TV is a bit like the film film, which is the backlight irradiation imaging after image, so the picture quality is good in addition to the panel, whether the backlight control is accurate enough is also very important. Buy LCD TV friends I am afraid will have a feeling of the above figure, if at night with an entry-level LCD TV to play dark picture, it is very easy to appear above the situation, we call it light leakage. It should be noted that, unless you turn off the backlight when you find a dark environment, as some brands do, there will be some light leakage. With the backlight off, there’s no way to guarantee the details of the dark side. Therefore, the light control performance of good TV on the market is very rare!
Three, a case: Hisense LED55EC760UC LCD TV evaluation
Hisense LED55EC760UC smart TV is equipped with 4-core Cortex A53 CPU, main frequency 1.2GHz, 6-core Mali 450 GPU and 4-core NEON coprocessor, combined with 1.5GB RAM and 8GB ROM, easily facing 4K video and large games. Ensure the smooth and comfortable experience effect. The new 2K to 4K correlation compensation technology, through the real-time analysis of 2K signal, so that 2K signal to 4K signal, image restoration rate also increased by 90%, the picture is more brilliant.
The general assessment is as follows:
1. Curved screens are really cool and look great from all angles.
2, the picture is clear and smooth, the resolution is very high, it is 4K quality;
3, the appearance of elegant atmosphere, ultra-narrow frame, feel that a few years will not be too outdated;
4, the most important price ratio, really good value for money, worth buying.
The above is about LCD TV what kind of good related introduction, hope to know what is LCD TV, and understand the LCD TV selection method, you can refer to our examples to choose the most suitable for their own LCD TV products oh.
