What is an LED monitor?

It is a monitor that gives a bright and colorful image. It is an upgraded form of LCD (liquid crystal display). These monitors play a perfect role in gaming, multimedia application, and workplaces. Moreover, it consumes less energy than other monitoring devices. In electronics, LED is a semiconductor device. It emits infrared and visible light when in contact with an electric charge.

LED Monitor and LED Display

Isn’t it surprising how monitor technology has been going forward over the years? No doubt, LED is a popular technology in monitor technologies.

You may wonder: What does an LED mean?

LED is a semiconductor that emits light when you apply a charge. To understand the LED symbol, you should know how current flows through a circuit.

In the circuit, the cathode is a negative terminal, and the anode is a positive terminal. Thus, this symbol contains anode and cathode terminals. It also includes arrows showing the emission of light.

What is an LED display?

It is a flat-panel display that works on the principle of diode light emission. It uses the same light-emitting diode technology. It is one of the advanced forms of display technology. It has the following characteristics:

  • Excellent display graphics
  • Low power consumption
  • Light in weight
  • Portability
  • High photoelectric conversion efficiency
  • Low driving voltage
  • Long service life and many others

There is a lot list of various types of these display screens. Moreover, these displays differ in different features and applications.

LED Monitor and LED Display

How does an LED monitor work?

The display consists of tiny red, green, and blue LEDs. They are closely packed together in a fixed pattern. These red, green, and blue colors combine to form a pixel.

It can create various colors by adjusting the intensity of the light-emitting diodes. Then, when you look at the LED monitor from a certain distance, you see the colored pixels as an image.

What is RGB?

RGB is a short form of red, green, and blue. We use these three colors to form all visible colors. We use this technology in almost all types of displays, including LEDs.

The edge-lit LED monitor:

In this type of monitor, LEDs are at the edges of the monitor. They are facing toward the center of a monitor to make an image. As the diodes are present on the edges, this edge-lit monitor only dims portions of the picture. It differs from the full dim you can obtain with full-array LED monitors.

But edge-lit monitors make it clean to view from various angles. Additionally, they’re the least expensive flat-panel displays.

The full array LED monitor:

In the case of a full array monitor, the diodes are present all around the screen. This kind of monitor gives you the following:

  • Brilliant colors
  • Richer images
  • Deeper blacks and whites.

Its dimming is finer. And you will notice that everything is like that; it is actual existence. As a result, these monitors are one of the best displays for gamers and film enthusiasts.

The direct-lit LED monitor:

It is different from the two displays that we have discussed above. First, it is because it has rows of light-emitting diodes behind it. Another feature that makes it different is that it does not use local dimming. As a result, it is unable to create absolute blacks. It provides grey tones instead. So, it is a low-quality monitor.

How does LED display work?

Now, let us look at the working of LED display screens. These displays work by using a vast collection of light-emitting diodes. We encapsulate these diodes into a flat panel. These diodes are either red, green, or blue. Each of these diodes is capable of emitting light of different brightness.

These LEDs then jointly form an image on display. Image formation depends upon the intensity of the individual LEDs. There is an array of pixels fixed on the panel.

DIP technology:

It is a Dual In-Line Package. It is a rectangular housing of an electronic component package. There are electrical connecting pins in two parallel rows. We can insert this package in a socket. It can also be through-hole mounted to a printed circuit board PCB.

DIP LED screens have separate light-emitting diodes for each color. For example, there are individual green, red, and blue diodes. You can recognize this technology from the two pins. They extend from the bottom of the LED display.

Power source:

It is one of the crucial components of the display screen. It plays an important role. More than 80% of the breakdown occurs due to power sources. So while selecting a display, you must consider its power source. Here the question arises of choosing a power source for your display screen.

Here is the answer to your question:

A. First, go for a good appearance. It means that it should have uniformity in its array. It should be excellent.

B. Second step is to check the efficiency of the power source. The energy-saving level of the power source depends upon its efficiency.

The efficiency must be higher than 80% for a suitable power source. We apply this condition when the power source is fully loaded.

C. The PFC value is also crucial in the case of efficiency. The low PF value will increase reactive power and cause huge power losses.

D. Forth step is to ensure the power stability of the power source. It will ultimately affect the working life of the LED display. We can relate it to the ripple and rise of temperature. The power source with good stability has a low surge and a slight temperature rise.
