Advantages: The color of the LCD is bright, and the screen resolution is high, and the outline of the edge is delicate. High static resolution, suitable for viewing scenes or colorful images. It also has low power consumption, no radiation, and flicker. At present, there are excellent products available on the market ranging from 5 inches to 82 inches.
Disadvantages: From the perspective of the imaging principle of liquid crystals, the smearing phenomenon of liquid crystal is impossible to cure. This makes the liquid crystal greatly reduced in dynamic resolution. Moreover, the all-black screen display of liquid crystals is not ideal. Since the backlight is always on, it is always incomplete in the dark. In terms of sense of hierarchy, LCD has no advantage at all. The main reason is the principle of liquid crystal back light imaging.
The Plasma Monitor (PDP) uses the principle of generating a color image by filling a mixture of two thin glass plates, applying a voltage to generate an ion gas, and then discharging the plasma gas and reacting with the phosphor in the substrate. A monitor made of plasma screens.
Advantages: The advantage of plasma monitoring is that products with large screens (32 inches or more) work well. High contrast, dynamic resolution, no smearing. Layering is better than LCD, and shading is excellent. Suitable for monitoring some very dynamic occasions, such as traffic, airports, entertainment and so on.
Disadvantages: It is also a technical problem to improve the plasma resolution. It is difficult to achieve on 42-inch products. At present, Hitachi, Samsung and some other manufacturers have related products listed in the domestic market. And the minimum plasma can only stay in the product specifications of more than 32 inches. Moreover, most of the plasma above 50 inches may reach the HD standard. Because the plasma emits light due to excitation of the silver powder, there is a burn-in and aging phenomenon, and it is not possible to view a still picture for a long period of time. Therefore, it is not suitable for monitoring.
LED monitoring refers to a monitor made of a liquid crystal panel having LightEmittingDiode (light emitting diode) as a light source; CCFL (cold cathode fluorescent lamp) is used as a light source for LCD monitoring. They use different backlights.
The main differences between these two backlight products are as follows:
a. LED display thinner;
b. LED more power saving;
c. LED life is longer;
d. LED has a wider color gamut;
Since e.LED is almost completely concentrated in the visible light frequency and has no ultraviolet rays and infrared rays, it has no heat and no radiation. It is a typical green light source. It can also be very clear under strong light and can work at minus 40 degrees at low temperatures.
f. Higher contrast.
Comparison of LCD Monitors and Other Similar Products
LCD Monitor LCD monitor: LCD monitor is also called LCDCCTVMonitor. Its imaging principle is that the liquid crystal in the display panel is controlled by the voltage to make the liquid crystal molecules rotate at different angles, and the light source is provided by the backlight tube to show red, Green, blue three colors. Through the different combinations of the three primary colors, the true color image is restored.
