[screen type]
At present, only the screen types of televisions are roughly classified into high-end OLED screens, mainstream IPS screens, and VA soft screens. 
High-end OLED screen:
1. OLED screens are flexible, bendable, and so on, which makes curved TV come into being. Nowadays, more and more users are pursuing larger-sized TVs, which also allows curved screens to exert their natural advantages, enabling the users to have a visual sense of being surrounded and providing a better visual experience. (Now there are LCD panel curved TV, but the screen display effect is not as good as OLED curved TV)
2. Compared with LCD, OLED has self-luminous characteristics. Due to its unique structure, it can emit light by itself without requiring a backlight, thereby reducing the screen backlight and the thickness of the light guide plate, which is why OLED TVs are usually very thin.
3, due to the self-luminous OLED characteristics, can effectively reduce the color deviation caused by the light source, can better reflect the deep black and bright white, while the color is more delicate and full.
4, OLED response faster, watching sports events, movie high-speed dynamic picture does not appear afterimages.
5, OLED color gamut is wider, OLED screen NTSC can reach 100%, and the general LCD screen NTSC floats between 72%-85%. Compared with LCD screens, OLEDs provide users with the most intuitive experience that the screen is more colorful and colorful.
Main IPS screen and VA soft screen: 
Overall performance of IPS screen is better than VA soft screen
1. The viewing angle is large, and the viewing angle of the IPS screen panel can reach 178 degrees, which means that the effect of viewing the screen from the front or the side is the same.
2, the color is true, IPS screen because of the color flip and brightness conversion and other performance, so that you appreciate from any angle, you can see the bright, saturated and natural high-quality images.
3, IPS screen screen can appear dynamic HD picture, especially suitable for moving image reproduction, no residual image and smear, is to watch digital high-definition video and fast motion picture, such as game, race game box action movie a good carrier.
However, IPS has some shortcomings compared to VA screens.
1. Serious light leakage: As the IPS screen adopts horizontal liquid crystal molecular arrangement, the viewing angle is increased, but the light penetrability is reduced. To better display bright colors, the luminance of the backlight is increased, so the light leakage phenomenon is extremely high on the IPS screen. In general, with the increase of screens, the problem of large-area edge light leakage has always been the criticism of IPS.
2, can not achieve high contrast: because IPS screen can not improve the penetration of the backlight to enhance the practice also let it lose the high-contrast competitive advantage, the general IPS static contrast between 2000: 1--3000:1. The static contrast of the AV screen can easily reach 5000:1.
However, considering the technical features of the integrated IPS and VA screens, IPS still has the upper hand. 
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
When it comes to the purchase of smart TVs, many small partners think that CPU, resolution, etc. are very important, and there are many online shopping guides for our reference. However, TV shopping is not so simple. Most of the purchase Raiders mention the screen resolution, memory size, picture quality engine, the number of CPU cores. Although these indicators are also very important, the fundamentals of picture quality - screen types - are not covered.
