The full name of plasma TV is PlasmaDisplayPanel, which is called plasma TV in Chinese. It is a device that injects mixed gas between two ultra-thin glass plates and applies voltage to illuminate with phosphor. Compared with CRT tube display, it has high resolution, large screen, ultra-thin, rich color and vivid. Compared with LCD, it has high brightness, high contrast, large viewing angle, bright colors and rich interfaces.
Plasma display technology can be divided into two types: DC-type PDP with electrodes in direct contact with gas and AC-type PDP with electrodes covering the dielectric layer. There are three main types of color PDPs researched and developed: single-substrate (also known as surface discharge) AC PDP, dual (also known as counter-discharge) AC PDP and pulse storage DC PDP.
1, the color reproduction ability is good, the display color is natural;
2. The dark field has a large dynamic range and rich image layering;
3, the image tailing time is small, the dynamic definition is high;
4, the viewing angle is large, the brightness uniformity is good;
5, easy to achieve large screen.
Disadvantages:1, the screen size is small, there is no small size model;
2. Larger volume, larger weight and higher power consumption;
3, due to high temperature discharge, easy to burn phenomenon;
4, the screen brightness is low, the graininess is more obvious;
5, the heat is large, the noise is also obvious.
The panel of the plasma screen is mainly composed of two parts, one is a front process (FrontProcess) close to the user's surface, including a glass substrate (GlassSubstrate), a transparent electrode (Transparent Electrode), a Bus electrode (Bus-Electrode), and a transparent Dielectric layer, MgO film (MgOThinFilm). The other is the Rear Process, which includes a Phosphor Layer, a BarrierRib, a Dielectric Layer, an Address Electrode, and a Glass Substrate. . Therefore, the phosphor that is responsible for the luminescence is not on the side close to the user, but on the inner part. Since the control circuit must be sandwiched between the front plate process and the back plate process, during the panel assembly process, the front and rear plates need to be accurately aligned and matched with the control circuit to ensure that there is no problem in the illumination. In this step, you will find that the LCD panel needs a backlight module, but the PDP does not need it because it is self-illuminating. Only the panel is not enough, because there is a high-voltage drive circuit, and the control circuit with different functions can meet the basic requirements of the screen. If you buy a plasma TV, most of them will be equipped with a dedicated TV box, because most of the image input or Tuner is designed in the TV box, so a complete plasma TV, including plasma screen and TV box.
The liquid crystal display is referred to as LCD (Liquid Crystal Display), which uses an organic compound having a regular molecular arrangement between a substance of a solid state and a liquid state, and is heated to exhibit a transparent liquid state, and after cooling, a substance having a turbid solid state of crystal particles appears.
The liquid crystal molecular structure used for the liquid crystal display is similar to that of a fine match stick, and is called a NemaTIc liquid crystal. A liquid crystal display manufactured using such a liquid crystal is also called an LCD (Liquid Crystal Display). In the liquid crystal television, a voltage is applied to the liquid crystal between the two glasses, and the screen is reproduced by molecular arrangement change and zigzag change. The screen is created by the collision of the electron group, and the screen is formed by the perspective reflection of the external light.
