A plasma display panel PDP is a type of flat panel display that uses small cells containing plasma : ionized gas that responds to electric fields. Plasma TVs were the first large over 32 inches diagonal flat panel displays to be released to the public. Since then, they have lost nearly all market share due to competition from low-cost LCDs and more expensive but high-contrast OLED flat-panel displays.
How Does an LED TV Work?
Modern televisions have a baffling array of acronyms, formats and tech jargon all designed to promote and explain their features. A liquid crystal display is a special flat panel that can block light, or allow it to pass. The panel is made up of segments with each block filled with liquid crystals. The colour and transparency of these blocks can be changed by increasing or reducing the electrical current. LCD crystals do not produce their own light, so an external light source like a florescent bulb is needed to create an image. These are far more efficient and smaller in size, meaning the TV can be narrower. These displays are backlit by an array of LEDs directly behind the screen.

One of the major difference between the LED and the LCD is that the LED uses the PN-Junction diode which emits light when the current passing through it, whereas LCD uses liquid crystal or plasma for visible light emission.

The liquid crystals are filled between the glass electrode and when the power is applied across it, the liquid crystal becomes energised and emits light. The LED using gallium arsenide and gallium phosphide which when heated emits visible light. The LED is used for showing the numeric and alphanumeric characters. On the other hand, the LCD has a thin layer of liquid crystal filamen t between the glass electrodes. When the power is applied across the electrodes they start emitting light energy in the form of photons.
RGB LEDs display is better among the three types of LED monitors as it uses red, green and blue diodes to produce the lifelike images with amazing contrast ratio. We all are familiar with the computer monitors. We spend time sitting in front of them for hours working, gaming or watching movies. A monitor is used to display the output of any computer system. A good display makes all the difference and no doubt enhances the user experience.
Introduction to Computing. Technology is evolving at an exponential pace while the outstanding gadgets of the past are becoming obsolete and the new technology is rapidly replacing the old one. The trend of change for computer users is more than the people belongs to any other field of life. The computer monitors have a special role in the use of the computer as the user gets every output on it. In order to give a better experience to the user, advanced technologies are being introduced and the new monitors are light in weight, better resolution, vivid colors and harmless to the eyes.
