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.
4inch Slim Gimbal Led Downlight
Rhein Lighting has developed a line of 4 inch slim gimbal Led Downlight with a junction box. This led gimbal recessed light is IC rated, which is permitted to be in contact with insulations in ceilings.
The 4-inch led gimbal down light use the new generation of LED chips with higher lumen ouput and lower power. 750LM consumes 9 Watts, which equals to 75W incandescent lamp, saving you up to 88% in energy costs.
The ultra-thin gimbal smart downlight is only 0.47 inches and requires as small as 2 inches ceiling spaces, fits various ceilings, and around joists. 5%-100% smooth dimming meets kinds of needs in applications such as kitchen, living room, bedroom, bathroom and common areas in your home or office.
Rhein Lighting is a professional manuafacturer of slim LED downlight, LED panel down light, Led Panel Light, Led Strip Light and Led Grow Light etc.
