Everyone should be familiar with the IPS hard screen. The highest user loyalty of the current mobile phone - Apple's iPhone is using this IPS hard screen, which is characterized by rich colors, viewing angle is very wide, almost can reach 180 degrees parallel. At the same time, because of its excellent color performance, IPS has achieved perfect performance for different colors, but there is a phenomenon of light leakage. Compared to VA screens, the performance of the black field may not be so pure, so each There are all good, every technology can not be perfect.
Second, soft screen
Let's talk about soft screens, soft screens are divided into MVA and PVA, which belong to the VA screen. Press the LCD panel by hand, the panel will have a small amount of water ripple or plum blossom.
MVA material screens are generally from Taiwan's panel makers, such as AUO, Chi Mei, etc. The panels they manufacture are generally used in middle and low-end TVs. Its advantages are low cost, color gamut, and color expressiveness. However, the disadvantage is that the viewing area is small. If you sit away from the front of the TV, you may see a large distortion in the TV viewing. In addition, the transparency is not as good as the other two screens.
PVA material screen compared with the same soft screen MVA, PVA brightness, contrast has a good performance, compared with MVA in the performance of the color and the performance of the black field is more perfect, wide viewing angle, not because of viewing position Oversaw and see the situation of distorted picture. Most of the Samsung TVs on the market today use PVA screens, which are also used by high-end products of other big brands.

Whether it's tangled up in TVs to watch best results or choose different kinds of LCD panels, as long as we feel comfortable in our experience, that is the TV we need. For flat-panel TVs, the larger the size of the TV in theory, the more powerful the visual impact, but it does not mean that the larger the screen size, the better the TV is for everyone. We don't have to worry too much about the size or texture of the screen. What you like is the best.
Why is the TV price gap of the same size so large?
The reason why smart TV prices vary so much is that the important reason comes from the panel. After plasma exits the historical stage, it depends on the LCD panels that are commonly used in smart TVs. The two most important aspects of the panel come from resolution and material. The higher the resolution, the better the viewing effect and the finer the picture. Panel materials are currently hard screens and soft screens in terms of large categories. The hard screen is represented by the IPS screen represented by LG. The manufacture of soft screens is divided into many parts. In general, it is divided into MVA and PVA screens. Today we come to chat about the smart TV screen.
