LCD TV is now the leading TV product, occupying the absolute advantage in the TV market, is the first choice of many families TV products. But the LCD TV product variety is very much, in the end which is the most cost-effective and the most satisfactory? Don’t worry, before understanding what kind of LCD TV is good, we need to know what LCD TV is in the end to make the appropriate measurement, let’s take a look below.
First, what is the LCD TV?
Liquid crystal is a substance between the solid and liquid state, is an organic compound with regular molecular arrangement, if it is heated will present a transparent liquid state, it is cooled will appear crystalline particles of cloudy solid state. It is because of this property that it is called liquid crystal. The molecular structure of liquid crystal used in liquid crystal displays is similar to that of a thin matchstick, and is called Nematic liquid crystal, and the liquid crystal displays made with such liquid crystal are called LCD. picture. Most families can afford to buy LCD TVs, and with the price of LCD TVs getting lower and lower, many people want to update their old TVs.
Second, the LCD TV how to buy?
1. Measure the TV’s color accuracy
A concept that is easy to confuse with the color gamut is the color depth of the TV panel. Mainstream LCD panels are used for each primary color 8bit color depth, and a Japanese manufacturer and launched a 10bit LCD panel drive technology, so there are always people will think that the high color depth brings a wider color gamut, and this is precisely a misconception. The benefit of using high bit is that the color accuracy will be greatly increased, and will not enhance the color gamut of the display device. Since flat-panel TVs have digital processing circuits inside, each color is represented by various binary values. Take 8bit as an example, an 8-bit binary number can represent a total of 256 values from 0-255, which means that a certain color has only 256 levels of difference, while with 10bit, the range of values will be extended to 0-1023, which can describe 1024 color levels. So for the same original signal, using high color depth is equivalent to describing the original signal with more precise order of magnitude, without changing the original signal itself. Therefore, high color depth can only make the display device performance of the color more accurate, the transition between colors more smooth, and the color gamut is not much to enhance the role.
2. Light control performance is really important
LCD TV structure is a bit like film movies, are backlight irradiation imaging layer out of the image, so the picture quality is good in addition to look at the panel, whether its backlight control is accurate enough is also very important. I’m afraid that friends who buy LCD TVs will be quite sensitive to the above chart, if you use an entry-level LCD TV at night to play a darker picture, it is easy to appear the above situation, we call it light leakage. It should be noted that, unless the backlight is turned off like some brands find all black environment, otherwise there will be a certain amount of light leakage. And turn off the backlight, the dark details and no way to ensure. Therefore, the light control performance of good TV sets on the market is a rare thing!
Third, an example: Hisense LED55EC760UC LCD TV review
Hisense LED55EC760UC smart TV is equipped with, 4-core Cortex A53 CPU with 1.2GHz, 6-core Mali 450 GPU and 4-core NEON co-processor, with the combination of 1.5GB RAM and 8GB ROM, easily facing 4K video and large games, ensuring a smooth and comfortable experience effect. The new 2K to 4K correlation compensation technology enhances the 2K signal to 4K signal through real-time analysis of the 2K signal, and the image restoration rate is also increased by 90% for a more colorful picture.
The overall evaluation is as follows.
1, curved screen is really cool, from all angles of the TV visual effects are great.
2, the picture is clear and smooth, the resolution is very high, and it is really 4K quality.
3, the appearance of elegant atmosphere, bezel super narrow, think more years will not be too outdated.
4, the most important value for money, really value for money, worth buying.
The above is a good introduction to what kind of LCD TV, I hope that after knowing what is LCD TV, and understand the purchase method of LCD TV, you can refer to the examples we cited to choose the most suitable for their LCD TV products Oh.
