Industrial and Medical Display
There are many kinds of LCD classification standards, which can be divided into passive matrix and active matrix according to the driving mode
Passive matrix: Passive matrix LCD can be divided into TN-LCD(TwistedNematic LCD), STN-LCD(SuperTN-LCD) and DSTN-LCD(Doublelayer STN-LCD).
Active matrix: Active matrix LCD, also known as TFT-LCD, is widely used at present. Tft-lcd is short for thin-filmliquid-Crystal Display
The TFT-thin Film Transistor
Liquid Crystal Display
Short for TFT-LCD Liquid-CrystalDisplay
Tft-lcd has been widely used in various display equipment due to its advantages of small size, light weight, low radiation, low power consumption and full color.
Functions of TFT-LCD structure
(1) Backlight plate module: provide the source of light;
(2) Upper and lower polarizing plates, TFT Glass Substrate, liquid crystal: forming polarized light, controlling the passage of light;
(3) Color filters: Provide TFT LCD red, green and blue (three primary colors of light) sources;
(4) ITO transparent conductive layer: provide transparent conductive path;
(5) Photo Spacer: Provide a fixed height for color filters and TFT Glass Substrate. As a space for liquid crystal infusion, and as a support for the upper and lower Glass layers.

Taking Sony Z9D as an example, it belongs to Sony's high-end brand series - BRAVIA, from the point of view of the use of the function, in fact, there is no very big difference with the ordinary smart TV. Whether it is smart operation or the use of television for large-scale games, screencasts, etc., this TV also has. But why can it buy 6 digits? This is actually related to its multi-definition technology and screen size. 
There are also some OLED TVs, because the TVs have lower panel yields and therefore prices are still high. In fact, currently television does not have a lot of breakthroughs in terms of functionality. The real difference lies in the quality of television.
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.
What is the function of a TV with a value of 500,000?
Although in the price war some time ago, TV prices once fell, giving consumers TV can actually evaluate the concept. But in fact, there are also some home appliances that are on the high end of the road and can even reach surprisingly high prices. I believe we all know that a few months ago, Wang Sicong bought the 499,999 yuan Sony Z9D TV, this kind of high-end TV exactly what kind of mystery? Judging from the picture quality, the Sony Z9D is equipped with 4K and HDR technology, and is equipped with an advanced version of the 4K HDR image processing chip X1 developed by Sony to control the brightness of the picture and create the most detailed picture effects. At the same time, the TV also has a Sony dynamic backlight system - the master version, this "black technology" can provide a long time effective light source, can be greatly improved twice, and the control is more accurate, so that the screen will not be blindly exposed, But it is closer to reality. Under the high light rendering effect, the picture will be more three-dimensional. The screen size of this TV has a very high impact on price. Sony Z9D itself uses dynamic backlight system - Master Edition, its backlight mode is not a direct type of ordinary TV backlight, but let each backlight can be independently controlled. To achieve this goal from the technical level requires very strong technical support, and if the picture is 100 inches, the technical difficulty required will increase exponentially. This is also the key to the current high price of large-screen televisions.
